Detailed ways

In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

It should be clear that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the present application. The singular forms "a", "said" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.

It should be understood that the term "and/or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and/or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character "/" in this article generally indicates that the associated objects before and after are in an "or" relationship.

Referring to FIG. 1 , a schematic diagram of the structure of a communication system provided by an embodiment of the present application is shown. As shown in FIG. 1 , the communication system includes an electronic device 10 and a target device 20. When the electronic device 10 establishes a communication connection with the target device 20, it can be achieved through some services. For example, when the target device 20 needs to establish a communication connection with the electronic device 10, it can be achieved through the Bonjour service. The Bonjour service here is a name given based on the open zero-setting network standard of the multicast domain name service, which can automatically discover computers, devices and services on the IP network. Bonjour uses the industrial standard IP protocol to allow devices to automatically discover each other without entering an IP address or configuring a DNS server. That is, the target device 20 can send a Bonjour service request message through the Bonjour service, and the request message carries the identification information of the device that needs to establish a communication connection. At this time, when the electronic device 10 receives the Bonjour service request message, it can obtain the response data of the Bonjour service and send the response data to the target device 20, and the target device 20 can establish a communication connection with the electronic device 10 according to the response data. In some technologies, in order to meet the low power consumption requirements of the electronic device 10, a low power consumption mode is usually provided in the electronic device 10. In the low power consumption mode of the electronic device 10, some functional modules in the electronic device 10 need to enter a dormant state, which may result in that some functions of the electronic device 10 may not be implemented in the low power consumption mode. In some technologies, when the electronic device 10 is in the low power consumption mode, since the processing module of the Bonjour service needs to switch to a dormant state, the electronic device 10 cannot respond to the Bonjour service when it is in the low power consumption mode, thereby making it impossible for the target device 20 to establish a communication connection with the electronic device 10, reducing the user experience. Of course, in the embodiment of the present application, the Bonjour service can also be replaced by other services with the same functions as the Bonjour service, and the embodiment of the present application does not limit this.

The electronic device 10 may be an image forming device, including but not limited to a printer, a copier, a fax machine, a scanner, and a multifunctional peripheral that performs the above functions in a single device. The target device 20 includes but is not limited to a mobile phone, a laptop, a personal digital assistant (PDA), a smart watch, a netbook, etc.

In response to the above problems, one embodiment of the present application provides a communication method, when the electronic device 10 is in low power mode, after receiving the target service request message, it can obtain the response data corresponding to the target service request message, that is, the target data, and send the target data to the target device 20, so that the target device 20 can establish a communication connection with the electronic device 10 through the target data. That is, the electronic device 10 can obtain the target data in advance when it is not in low power mode. In this way, when the electronic device 10 is in low power mode, it can also respond to the target service request message, so that the target device 20 can establish a communication connection with the electronic device 10 through the target service, thereby achieving the purpose of meeting the low power consumption requirements of the electronic device 10 while also establishing a communication connection with the target device 20 through the target service. The following is a detailed description.

Referring to FIG2 , a flow chart of a communication method provided in an embodiment of the present application is shown. The method is applied to an electronic device 10, as shown in FIG1 , and the method includes:

Step S201 : When the electronic device 10 is in a low power consumption mode, in response to a target service request message, target data is sent to the target device 20 , so that the target device 20 can establish a communication connection with the electronic device 10 according to the target data.

The target device 20 is a device that sends a target service request message.

In an embodiment of the present application, when the target device 20 needs to establish a communication connection with the electronic device 10, it can be achieved through the target service. At this time, the target device 20 can send a target service request message to the electronic device 10. In order to establish a communication connection with other devices through the target service even in low power consumption mode, the electronic device 10 can pre-acquire target data in non-low power consumption mode. In this way, in low power consumption mode, when the electronic device 10 receives the target service request message, it means that the target device 20 wants to establish a communication connection with the electronic device 10 through the target service. At this time, the electronic device 10 can send the target data to the target device 20 in response to the target service request message, so that the target device 20 can establish a communication connection with the electronic device 10 according to the target data after receiving the target data.

As a possible implementation, as shown in FIG3 , the method further includes:

Step S202: before entering the low power consumption mode, storing the target data in the first storage area.

In an embodiment of the present application, the electronic device 10 needs to obtain the target data before entering the low power mode, so that the target data can be sent to the target device 20 when the target service request message is received in the low power mode. In some feasible implementations, the above-mentioned target data can obtain real-time network parameters from the network module of the electronic device 10 when the network identification information of the electronic device 10 changes, and generate the target data according to the target format of the above-mentioned target data and the real-time network parameters. Among them, the network module here refers to the component in the software module independent of the hardware module and the firmware module in the electronic device 10, which provides network services for the electronic device 10. Since the electronic device 10 may not use the target data immediately after obtaining it, the electronic device 10 needs to store the target data first. Based on this, in an embodiment of the present application, the electronic device 10 is used to store the target data in the first storage area when it is in a non-low power mode, so that the electronic device 10 can obtain the target data by directly or indirectly accessing the first storage area in the low power mode, so that the electronic device 10 can establish a connection with the target device based on the obtained target data.

That is, in order to be able to respond to the target service request message in low power mode, the electronic device 10 can obtain the target data when it is not in low power mode. At this time, when the electronic device 10 is in non-low power mode, the electronic device 10 can first obtain the data corresponding to the target service as the target data. After the electronic device 10 obtains the target data, since the target data is not used immediately, it can be stored in a storage area first. In order to be able to obtain the target data in the storage area when the electronic device 10 is in low power mode, the storage area that can be read by the electronic device 10 in low power mode can be used as the first storage area, and the target data can be directly stored in the first storage area.

In some embodiments, the electronic device 10 can store the data corresponding to the target service directly as the target data in the first storage area. Alternatively, in order to reduce the occupied storage space, some data can be extracted from the data of the target service as the target data. In some embodiments, only the data related to the target service in the data of the target service can be used as the target data. For example, the data of the target service includes the IP address information, name information, functional attribute information of the electronic device 10, and the service name of the electronic device 10 in the target service. At this time, since the IP address information and name information of the electronic device 10 will also be used when the electronic device 10 implements other functions, the functional attribute information of the electronic device 10 and the service name of the electronic device 10 in the target service are only related to the target service. At this time, the functional attribute information of the electronic device 10 and the service name of the electronic device 10 in the target service can be used as target data and stored in the first storage area.

As a possible implementation, before entering the low power consumption mode, storing the target data in the first storage area includes:

Before entering the low power mode, if the network identification information of the electronic device 10 changes, the target data corresponding to the target service is stored in the first storage area. Alternatively, if the electronic device 10 is restarted, the target data is stored in the first storage area; or, if the electronic device 10 determines that it needs to enter the low power mode at the same time or after, the target data is stored in the first storage area; if the electronic device 10 determines that it needs to perform the system initialization required to enter the low power mode, the target data is stored in the first storage area; or, the electronic device 10 stores the target data in the first storage area during the process of performing the system initialization required to enter the low power mode.

That is, in order to reduce the power consumption of the electronic device 10, the target data can be reacquired only when the target data changes, and the reacquired target data is stored in the first storage area. Because the target data is generated based on the identification information of the electronic device 10. Generally, the network identification information in the electronic device 10 may change due to the implementation of certain functions or the user's settings. For example, the user sets the IP address and other information of the electronic device, resulting in a change in the network identification information. Therefore, the electronic device 10 can determine whether the target data has changed by directly identifying whether the network identification information in the electronic device 10 has changed. If it has changed, it is necessary to acquire the target data and store the target data in the first storage area. Or when the electronic device 10 is restarted, the electronic device 10 can reacquire the target data and store the target data in the first storage area.

In some embodiments, the electronic device 10 can detect in real time or periodically whether the network identification information of the electronic device 10 has changed. For example, the electronic device 10 can periodically obtain the network identification information of the electronic device 10, compare the network identification information of the electronic device 10 currently obtained with the network identification information of the electronic device 10 obtained last time, and determine whether they are the same. If they are the same, it means that the network identification information of the electronic device 10 has not changed. If they are different, it means that the network identification information of the electronic device 10 has changed. At this time, the electronic device 10 needs to re-acquire the target data from the network module 1021, and re-store the target data to the first storage area to update the target data in the first storage area.

Alternatively, in some embodiments, when the electronic device 10 is restarted, the data stored in the first storage area may be released, or the network identification information of the electronic device 10 may change due to the restart of the electronic device 10. In this case, the electronic device 10 needs to reacquire the target data after the electronic device 10 is started and store the target data in the first storage area.

Alternatively, since the electronic device 10 stores the target data in the first storage area in order to obtain the target data when the electronic device 10 is in a low power mode, so as to respond to the target service request message. Therefore, the electronic device 10 can store the target data in the first storage area before entering the low power mode if the network identification information of the electronic device 10 changes; or, if the electronic device 10 is restarted, the target data is stored in the first storage area; or, if the electronic device 10 determines that it needs to enter the low power mode at the same time or after, the target data is stored in the first storage area; if the electronic device 10 determines that it needs to enter the system initialization required for the low power mode, the target data is stored in the first storage area; or, if the electronic device 10 is in the process of executing the system initialization required for entering the low power mode, the target data is stored in the first storage area. In this way, the utilization rate of the first storage area when the electronic device 10 is in a non-low power mode can be improved.

As a possible implementation, since not all storage areas in the electronic device 10 are in a readable and writable state in the low power consumption mode. That is, when the electronic device 10 is in the low power consumption mode, only some storage areas are readable and writable. The electronic device 10 can be used to store the acquired target data in the first storage area first. The first storage area can be a storage area that the electronic device 10 can read in the low power consumption mode. At this time, before the above step S201, as shown in FIG4, the method further includes:

Step S203: Acquire target data from the first storage area.

In an embodiment of the present application, after the electronic device 10 stores the target data in the first storage area in a non-low power consumption mode, the electronic device 10 can read the target data in the first storage area when it needs to obtain the target data. In some embodiments, the electronic device 10 can be in a low power consumption mode, and when receiving a target service request message, the electronic device 10 can read the target data from the first storage area because it needs to respond to the target service request message.

Alternatively, in some embodiments, for ease of use, the electronic device 10 may also read the target data from the first storage when it is not switched to the low power mode. In this way, when it enters the low power mode, if it receives a target service request message, it can directly send the acquired target data as response data to the target device 20.

That is to say, in the embodiment of the present application, the electronic device 10 can obtain the target data in the low power consumption mode, and can also obtain the target data when not switching to the low power consumption mode, as long as the target data is obtained before sending the target data to the target device. The embodiment of the present application does not limit the timing of the electronic device 10 obtaining the target data.

As another possible implementation, the electronic device 10 may be used to store the acquired target data in a first storage area. The first storage area may be a storage area that the electronic device 10 can read in a low power consumption mode. At this time, before the above step S201, as shown in FIG5 , the method further includes:

Step S204: Store the target data stored in the first storage area in the second storage area, and obtain the target data from the second storage area.

Among them, the second storage area is a storage area that can be read when the electronic device 10 is in low power mode. That is, when the first storage area where the electronic device 10 stores the target data is not the data that the electronic device 10 can read in low power mode, it means that the electronic device 10 cannot directly obtain the target data in the first storage area in low power mode. At this time, the electronic device 10 needs to first store the target data stored in the first storage area to the second storage area that can be read in low power mode. That is, the electronic device 10 can read the target data stored in the first storage area and store it in the second storage area.

After storing the target data in the second storage area, the electronic device 10 can read the target data from the second storage area when it needs to obtain the target data. In some embodiments, the electronic device 10 can be in low power mode, and when receiving a target service request message, the electronic device 10 can first read the target data from the second storage area because it needs to respond to the target service request message.

The aforementioned implementation states that the first storage area is not an area that the electronic device 10 can read in low power mode, and the target data stored in the first storage area must be stored in the second storage area before the target data is sent to the target device. It should be supplemented that in other implementations, the first storage area can also be an area that the electronic device 10 can read in low power mode, and before the target data is sent to the target device, the electronic device 10 stores the target data stored in the first storage area in the second storage area, so that the target data can be obtained from the second storage area when the electronic device 10 is in low power mode.

As a possible implementation, as shown in FIG6 , the above step S201 sends the target data to the target device in response to the target service request message, including:

Step S2011: Obtain a service request message.

Step S2012: Determine whether the service request message is a target service request message.

Step S2013: If the service request message is a target service request message, the target data is sent to the target device 20 in response to the target service request message.

That is, since other devices can usually send service request messages by broadcasting, the service request message received by the electronic device 10 may not be a request message for establishing a communication connection with the electronic device 10, but for realizing other functions. Based on this, when the electronic device 10 receives a service request message, it is necessary to first determine whether the service request message is a target service request message for establishing a communication connection with the electronic device 10. When it is determined that the received service request message is a target service request message, the electronic device 10 determines that it needs to respond to the target service request message, and at this time the electronic device 10 can send the target data as a response message to the target device 20.

In some embodiments, the service request message generally includes service information, which is used to indicate the service requested by the service request. When the service information indicates that the service request message is used to establish a communication connection with the electronic device 10, the electronic device 10 can determine that the received service request message is the target service request message.

In a possible implementation manner, the service information includes: at least one of: service name information and service device identification information.

That is, when the service information includes the name information of the service, it means that the service request message contains the name of the service requested by the target device. At this time, the first chip 101 can determine whether the service requested by the target device 20 is a service that the electronic device 10 can provide based on the name information of the service in the service request message. When the name information of the service in the service request message matches the service that the electronic device 10 can provide, it can be determined that the service request message is a target service request message. At this time, the electronic device 10 needs to respond to the target service request message, and the electronic device 10 can send the target data as a response message to the target device 20. Alternatively, if the name information of the service in the service request message does not match the service that the electronic device 10 can provide, it means that the service request message is not a target service request message, and the electronic device 10 does not need to respond to it.

Alternatively, when the service information includes the device identification information of the service, the electronic device 10 can determine whether the service request message is a target service request message based on the device identification information of the service in the service request message. In some embodiments, the electronic device 10 can determine whether the service message is a target service request message by detecting whether the device identification information of the service in the service request message is the identification information of the electronic device 10. If the device identification information of the service in the service request message is the identification information of the electronic device 10, the electronic device 10 determines that the received service request message is a target service request message, and the electronic device 10 needs to respond to the service request message. At this time, the electronic device 10 can send the target data as a response message to the target device 20. Otherwise, the electronic device 10 determines that the received service request message is not a target service request message, and the electronic device 10 does not need to respond to it.

As a possible implementation, the device identification information of the service may include at least one of the name information of the device and the service name information of the device. That is, the device identification information of the service may be the name information of the device, or the service name information registered by the device in the target service, or other information of the device that can uniquely identify the device, which is not limited in this application.

When the device identification information of the service includes the name information of the device, the electronic device 10 can detect whether the name information of the device contained in the service request message is the name information of the electronic device 10 when receiving the service request message. If the name information of the device contained in the service request message is the name information of the electronic device 10, it is determined that the received service request message is a target service request message. At this time, the electronic device 10 needs to respond to the target service request message, and the electronic device 10 can send the target data to the target device 20.

Alternatively, if the device name information included in the service request message is not the name information of the electronic device 10, the electronic device 10 may determine that the received service request message is not the target service request message, and the electronic device 10 does not respond to the service request message.

When the device identification information of the service includes the service name information of the device, the electronic device 10 can detect whether the service name information of the device contained in the service request message is the service name information registered by the electronic device 10 in the target service when receiving the service request message. If the service name information of the device contained in the service request message is the service name information of the electronic device 10, it is determined that the received service request message is the target service request message. At this time, the electronic device 10 needs to respond to the target service request message, and the electronic device 10 can send the target data to the target device 20.

Alternatively, if the service name information of the device contained in the service request message is not the service name information of the electronic device 10, it is determined that the received service request message is not the target service request message, and the electronic device 10 does not respond to the service request message. As a possible implementation, when the electronic device 10 is an image forming device, the service name information includes at least one of a printer service, a scanning service, and a fax service. At this time, when the electronic device 10 receives the service request message, it can detect the service name information contained in the service request message. If the service name information includes at least one of a printer service, a scanning service, and a fax service, it means that the received service request message is a target service request message for establishing a communication connection with the image forming device, and the electronic device 10 can send the target data to the target device 20.

Of course, the electronic device may also comprehensively determine whether the aforementioned service request message is the target service request information based on the device identification of the aforementioned service and the name information of the service, and the embodiment of the present application does not limit this.

As a possible implementation, the electronic device 10 is used to establish a communication connection with the target device 20 through the target service. At this time, the above-mentioned sending of the target data to the target device 20 includes:

The target data in the target format are encapsulated according to the data format of the target service to obtain the target data in the target format; the target data in the target format are network encapsulated, and the network-encapsulated target data are sent to the target device 20 .

That is, the target service has its own data format. When the electronic device 10 sends the target data to other devices, it is necessary to encapsulate the target data according to the data format of the target service, so that when other devices receive the target data, they can parse the target data according to the data format of the target service and obtain the relevant data of the electronic device 10 they need. Based on this, when the electronic device 10 sends the target data to the target device 20, it is necessary to first encapsulate it into data in the data format of the target service. At this time, after the electronic device 10 obtains the target data, it can first encapsulate the target data according to the data format of the target service to obtain the target data in the target format. In some embodiments, if the target data is only part of the data of the target service, when the target data is encapsulated according to the data format of the target service, the electronic device 10 also needs to supplement the content that is not in the target data according to the data format of the target service. For example, the data format of the target service contains IP address information, name information, functional attribute information of the electronic device 10 and service name information of the electronic device 10. At this time, if the target data only includes the functional attribute information of the electronic device 10 and the service name information of the electronic device 10, when the target data is encapsulated according to the data format of the target service, the electronic device 10 needs to first obtain the IP address information and name information of the electronic device 10. The IP address information, name information, functional attribute information of the electronic device 10, and service name information of the electronic device 10 are encapsulated according to the data format of the target service. After the encapsulation of the target data is completed, the target data in the target format can be obtained. In order to reduce the storage space used by the target data, when the electronic device 10 is in low power consumption mode, after receiving the target service request message, when it needs to send the target data to the target device 20, it can perform the above-mentioned encapsulation process of the target data according to the data format of the target service.

After obtaining the target data in the target format, when the electronic device 10 needs to send the target data to the target device 20, the electronic device 10 can transmit the target data to the target device 20 through network transmission. Therefore, in order to be able to transmit the target data to the target device 20, the electronic device 10 needs to first perform corresponding network encapsulation on the target data in the target format, and then transmit the network-encapsulated target data to the target device 20 through the network. At this time, when the electronic device 10 performs network encapsulation on the target data in the target format, it can determine the data encapsulation format according to the transmission protocol it adopts, and then encapsulate the target data in the corresponding format.

In some embodiments, the electronic device 10 can perform network transmission of the target data through TCP (Transmission Control Protocol). At this time, the electronic device 10 can encapsulate the target data in the target format according to the data format of TCP to form a TCP data packet, and transmit the TCP data packet to the target device 20 through the network.

In some embodiments, the electronic device 10 may also perform network transmission of the target data via UDP (User Datagram Protocol). At this time, the electronic device 10 may encapsulate the target data in the target format according to the data format of UDP to form a UDP data packet, and transmit the UDP data packet to the target device 20 via the network.

Of course, the electronic device 10 can also perform network transmission of the target data through other transmission protocols. At this time, the electronic device 10 can perform corresponding network encapsulation of the target data according to the transmission protocol, and the embodiment of the present application does not limit this.

As a possible implementation method, when the electronic device 10 needs to send the target data after network encapsulation to the target device 20, the target data can be transferred to the output interface of the electronic device 10 through DMA (Direct Memory Access), and the encapsulated target data can be sent out through the output interface.

Referring to FIG. 7, a schematic diagram of the structure of another electronic device provided in an embodiment of the present application. Different functions of the electronic device 10 can be implemented by different chips therein. As shown in FIG. 7, the electronic device 10 includes a first control unit 101 and a second control unit 102. Among them, the first control unit 101 and the second control unit 102 can be two different chips in the electronic device 10. In some feasible embodiments, the first control unit 101 and the second control unit 102 can be MCUs (microprocessor units) to provide different combination controls for different application scenarios. Optionally, the first control unit 101 and the second control unit 102 can be integrated on the same SOC (System on Chip) to provide hardware support for the electronic device 10. Optionally, in some feasible embodiments, the first control unit 101 and the second control unit 102 can also be integrated in the same MCU to provide different combination controls for different application scenarios. Of course, in other embodiments, the first control unit and the second control unit can also include the aforementioned MCU and the corresponding peripheral single channel, which is not limited in the embodiment of the present application. Among them, the power consumption of the first control unit 101 is relatively small, and the electronic device can also work normally when it is in a low power consumption mode without switching to a sleep state. The second control unit 102 has a relatively large power consumption and can establish a communication connection with the target device 20 through the target service. That is, when the electronic device 10 receives the target service request message sent by the target device 20, the second control unit 102 can determine the response data when determining that the target service request message is a request to establish a communication connection with the electronic device 10, and send a response message to the target device 20 based on the response data, so that the target device 20 can establish a communication connection with the electronic device 10 based on the response message when receiving the response message.

In some embodiments, the target service may be a Bonjour service. The Bonjour service here is a name given by an open zero-setting network standard based on a multicast domain name service, which can automatically discover computers, devices and services on an IP network. Bonjour uses an industrial standard IP protocol to allow devices to automatically discover each other without entering an IP address or configuring a DNS server. Therefore, the target device 20 can establish a communication connection with the electronic device 10 through the Bonjour service. The target device 20 sends a Bonjour service request message to the electronic device 10, and the request message may carry the service information requested by the target device 20, and the service information is used to indicate the relevant information of the service requested by the target device 20. When the second control unit 102 in the electronic device 10 receives the Bonjour service request message, when determining that the Bonjour service request message is a request to establish a communication connection with the electronic device 10, the second control unit 102 may first determine the response data of the Bonjour service, and send the response data as a response message to the target device 20. At this time, the target device 20 can establish a communication connection with the electronic device 10 based on the received response message. Of course, in the embodiment of the present application, the Bonjour service can also be replaced by other services with the same functions as the Bonjour service, and the embodiment of the present application is not limited to this.

In order to meet the energy consumption requirements, the electronic device 10 needs to switch to a low power consumption mode in a non-low power consumption state. However, the power consumption of the second control unit 102 is relatively large. When the electronic device 10 is in a low power consumption mode, the second control unit 102 needs to switch to a dormant state and cannot work. At this time, if the electronic device 10 receives a Bonjour service request message, the electronic device cannot respond to the Bonjour service request message if the second control unit 102 is not awakened. When the second control unit 102 is awakened, the electronic device cannot meet the low power consumption requirements.

In an embodiment of the present application, the second control unit 102 may pre-acquire the target data and store the target data in the first storage area. The first storage area is a storage area that the second control unit 102 cannot read when in low power consumption mode, and is also a storage area that the first control unit 101 can read when in low power consumption mode. The first control unit 101 may acquire the target data from the first storage area before the electronic device 10 sends the target data to the target device. When the electronic device 10 is in low power consumption mode, the second control unit 102 switches to a dormant state. When the electronic device 10 receives a target service request message, the first control unit 101 sends the target data as a response information of the target service request message to the target device 20, so that the target device 20 can establish a communication connection with the electronic device 20 according to the target data. That is, when the electronic device is in low power consumption mode, the first control unit 101 can acquire the target data by directly accessing the first storage unit. In other embodiments, the first control unit 101 can also acquire the target data indirectly through the first storage unit. Referring to the above description, it can be seen that, for example, the electronic device stores the target data stored in the first storage area in the second storage area, and the first control unit 101 acquires the target data by accessing the above second storage area. Of course, in other embodiments of the present application, the first storage area may also be an area that is not readable by the second control unit 102 in the low power consumption mode, and the embodiments of the present application are not limited to this.

Thus, in the embodiment of the present application, when the electronic device 10 is in the low power consumption mode, it can also respond to the target service request message, so that the target device 20 can establish a communication connection with the electronic device 10 through the target service, thereby achieving the purpose of meeting the low power consumption requirement of the electronic device 10 and establishing a communication connection with the target device 20 through the target service. The following is a detailed description.

Referring to FIG. 7 , it is a schematic diagram of the structure of an electronic device provided in an embodiment of the present application. The electronic device 10 includes:

The second control unit 102 is used to obtain target data and store the target data in the first storage area.

The target data is the data required when the electronic device 10 establishes a communication connection with other devices through the target service.

The first control unit 101 is configured to obtain target data from a first storage area before the electronic device 10 sends the target data to a target device.

The second control unit 102 is further configured to switch the electronic device to a sleep state when the electronic device is in a low power consumption mode.

The first control unit 101 is further configured to send target data to the target device 20 in response to the target service request message when the electronic device 10 is in the low power consumption mode, so that the target device 20 can establish a communication connection with the electronic device 10 according to the target data. The target device 20 is a device that sends the target service request message. In some optional implementations, the target device 20 may be a PC terminal or a mobile phone terminal, in particular, a PC terminal loaded with an IOS system and a mobile phone terminal loaded with an IOS system.

In an embodiment of the present application, since the electronic device is in a low power consumption mode, the second control unit 102 needs to switch to a sleep state and cannot work normally. In order to ensure that the target service request message can be responded to when the electronic device 10 is in a low power consumption mode. The second control unit 102 or the first control unit 101 can obtain the target data in advance before sending the target data to the target device, and store the target data of the target service in the first storage area. The first storage area is a storage area that can be read and written by the second control unit 102 and the first control unit 101. Since the first control unit 101 is a chip that can work normally without switching to a sleep mode when the electronic device 10 is in a low power consumption mode. Therefore, when the electronic device 10 is in a low power consumption mode, the target service request message needs to be responded to by the first control unit 101. In this way, the first control unit 101 needs to obtain the target data first. Since the second control unit 102 cannot read the first storage area when the electronic device 10 is in low power mode, in order to ensure that the first control unit 101 can obtain the target data, the second control unit 102 or the first control unit 101 needs to store the target data in the first storage area before the electronic device 10 enters the low power mode, so that the first control unit 101 can obtain the target data from the first storage area. In this way, when the electronic device switches to the low power mode, the second control unit 102 switches from the working state to the dormant state. At this time, if the target device 20 sends a target service request message to the electronic device 10, after the electronic device 10 receives the target service request message, the first control unit 101 responds to the target service request message. At this time, the first control unit 101 can obtain the target data, use the target data as the response data of the target service request message, and send the target data to the target device 20, so that the target device 20 can establish a communication connection with the electronic device 10 according to the target data.

That is, when the electronic device 10 switches to the low power mode, the second control unit 102 needs to switch to the dormant state. That is, in the low power mode of the electronic device 10, in order to reduce power consumption, the second control unit 102 with large power consumption needs to switch to the dormant state and no longer perform data processing. However, due to the low power consumption, the first control unit 101 can perform normal data processing without switching to the dormant state when the electronic device 10 is in the low power mode. At this time, if the target device 20 needs to establish a communication connection with the electronic device 10 through the target service, a target service request message is sent to the electronic device 10. Since the electronic device 10 is in the low power mode, the second control unit 102 switches to the dormant state, so the first control unit 101 needs to respond to the target service request message accordingly. Since the first control unit 101 obtains the target data in the first storage area before the electronic device 10 sends the target data to the target device, the first control unit 101 can send the acquired target data as a response message of the target service request message to the target device 20 after receiving the target service request message. When receiving the target data, the target device 20 may establish a communication connection with the electronic device 10 according to the received target data.

That is, in the embodiment of the present application, when the electronic device 10 is in the low power consumption mode, if a target service request message is received, it is not necessary to wake up the second control unit 102 from the sleep state to the working state, but the first control unit 101 in the working state responds. Since the first control unit 101 has obtained the target data from the first storage area and responded to the target service request message, the first control unit 101 can send the target data as response data to the target device 20, so that the target device 20 can establish a communication connection with the electronic device 10 according to the received target data.

Since the second control unit 102 needs to switch to a dormant state when the electronic device is in a low power consumption mode. Therefore, the second control unit 102 cannot send the data of the target service as response data to other electronic devices. Therefore, the second control unit 102 or the first control unit 101 stores the data of the target service in the first storage area before the electronic device 10 runs in a low power consumption mode. At this time, the second control unit 102 or the first control unit 101 can store the data of the target service as target data in the first storage area. It is also possible to extract part of the data of the target service as target data in order to reduce the occupied storage space. In some embodiments, the data related to the target service in the data of the target service can be used as target data. For example, the data of the target service includes the IP address information, name information, functional attribute information of the electronic device 10, and the service name of the electronic device 10 in the target service. At this time, since the IP address information and name information of the electronic device 10 are also used when the electronic device implements other functions, the functional attribute information of the electronic device 10 and the service name of the electronic device 10 in the target service are only related to the target service. At this time, the functional attribute information of the electronic device 10 and the service name of the electronic device 10 in the target service may be stored in the first storage area as target data.

In some embodiments, before the electronic device 10 operates in low power consumption mode, the second control unit 102 or the first control unit 101 can periodically obtain target data and store it in the first storage area, so that the target data stored in the first storage area can be updated in time when the target data changes.

In some embodiments, in order to reduce the power consumption of the electronic device 10, the target data can be obtained only after the electronic device 10 is started, or when the network identification information of the electronic device 10 changes, and the obtained target data is stored in the first storage area. Since the target data is generated based on the identification information of the electronic device 10, in general, the network identification information in the electronic device 10 may change due to the implementation of certain functions or user settings. For example, the IP address of the electronic device, etc. Therefore, it is possible to determine whether the target data has changed by identifying whether the network identification information in the electronic device 10 has changed. Based on this, the second control unit 102 or the first control unit 101 is specifically used to: if it is identified that the network identification information of the electronic device 10 has changed or the electronic device 10 has been restarted, the real-time network parameters are obtained from the network module of the electronic device 10, and the target data is generated according to the target format and real-time network parameters of the target data, and the target data is stored in the first storage area. Alternatively, when the electronic device 10 determines that the system initialization required to enter the low power consumption mode is required or the electronic device 10 is in the process of executing the system initialization required to enter the low power consumption mode, the real-time network parameters are obtained from the network module of the electronic device 10, and the target data is generated according to the target format and real-time network parameters of the target data, and the target data is stored in the first storage area. The network module here refers to a component of a software module in the electronic device 10 that is independent of the hardware module and the firmware module, and provides network services for the electronic device 10.

That is, the second control unit 102 or the first control unit 101 can detect in real time or periodically whether the network identification information of the electronic device 10 has changed. In some embodiments, the second control unit 102 or the first control unit 101 periodically obtains the network identification information of the electronic device 10, compares the network identification information of the electronic device 10 currently obtained with the network identification information of the electronic device 10 obtained last time, and determines whether they are the same. If they are the same, it means that the network identification information of the electronic device 10 has not changed; if they are different, it means that the network identification information of the electronic device 10 has changed. At this time, the second control unit 102 or the first control unit 101 re-acquires the target data, and re-stores the target data to the first storage area to update the target data in the first storage area.

When the electronic device 10 is restarted, the data stored in the first storage area may be released. At this time, the second control unit 102 or the first control unit 101 obtains real-time network parameters from the network module of the electronic device 10 after the electronic device 10 is started up, generates target data according to the target format of the above target data and the real-time network parameters, and stores the target data in the first storage area.

In a possible implementation, the second control unit 102 is specifically configured to: before the electronic device 10 sends the target data to the target device, obtain the target data and store the target data in the first storage area.

That is, since the second control unit 102 or the first control unit 101 stores the target data in the first storage area, it is to enable the first control unit 101 to obtain the target data from the first storage area when the electronic device 10 is in a low power mode, so as to respond to the target service request message. Since when the electronic device 10 is in a non-low power mode, the target service request message is directly responded to by the second control unit 102, even if the target data is stored in the first storage area, the first control unit 101 will not use it. Therefore, the second control unit 102 can obtain the target data and store the target data in the first storage area before the electronic device 10 sends the target data to the target device. In this way, the utilization rate of the first storage area when the electronic device 10 is in a non-low power mode can be improved.

Of course, in other implementations, the first control unit 101 may be specifically configured to obtain the target data and store the target data in the first storage area before the electronic device sends the target data to the target device.

As a possible implementation method, the second control unit 102 is specifically used to: before the electronic device 10 sends the target data to the target device, obtain real-time network parameters from the network module of the electronic device 10, generate target data according to the target format of the above target data and the real-time network parameters, and store the target data in the first storage area.

As a possible implementation, after the first control unit 101 obtains the target data from the first storage area, since the first control unit 101 usually does not immediately receive the target service request message, the first control unit 101 may first store the target data in the second storage area. Based on this, the first control unit 101 is further configured to: store the target data obtained from the first storage area in the second storage area.

The second storage area is a storage area that can be read by the first control unit 101 when the electronic device is in the low power consumption mode.

As a possible implementation method, after the second control unit 102 obtains the target data from the first storage area, it can store the target data obtained from the first storage area in the second storage area, wherein the second storage area is an area that can be read by the first control unit 101 when the electronic device is in low power consumption mode.

At this time, when the electronic device 10 is in the low power consumption mode, in response to the target service request message, sending the target data to the target device 20 includes:

When the electronic device 10 is in the low power consumption mode, in response to the target service request message, the target data is acquired from the second storage area; and the target data is sent to the target device 20 .

That is, since not all storage areas in the electronic device 10 are in a readable and writable state in the low power consumption mode. That is, when the electronic device 10 is in the low power consumption mode, only part of the storage area is readable and writable. The first storage area is a storage area that can be read by the first control unit 101 and written by the second control unit 102. When the electronic device 10 is in the low power consumption mode, there is a possibility that the first storage area is a storage area that cannot be read and written. Therefore, the first control unit 101 can read the target data from the first storage area before the electronic device 10 sends the target data to the target device. After reading the target data, the first control unit 101 can store it first. At this time, the first control unit 101 can store the target data in the storage area where the first control unit 101 can perform read and write operations when the electronic device 101 is in the low power consumption mode, that is, the second storage area. That is, in order to obtain the target data when the electronic device 10 is in the low power consumption mode, the first control unit 101 can store the target data obtained from the first storage area in the second storage area.

At this time, if the electronic device 10 receives the target service request message, the first control unit 101 can read the target data stored therein in the second storage area, and send the target data to the target device 20 as a response message.

In one possible implementation, the first control unit 101 is specifically used to: when the electronic device 10 is in a low power consumption mode, if a service request message is received, determine whether the service request message is a target service request message; if it is determined to be a target service request message, obtain the target data from the second storage area and send the target data to the target device 20.

That is, since other devices can usually send service request messages by broadcasting, the service request message received by the electronic device 10 may not be a request message for establishing a communication connection with the electronic device 10, but for realizing other functions. Based on this, when the first control unit 101 receives a service request message, it is necessary to first determine whether the service request message is a target service request message for establishing a communication connection with the electronic device 10. When it is determined that the received service request message is a target service request message, the first control unit 101 determines that it needs to respond to the target service request message. At this time, the first control unit 101 can obtain the target data from the second storage area and send the target data as a response message to the target device 20.

In some embodiments, the service request message generally includes service information, which is used to indicate the service requested by the service request. When the service information indicates that the service request message is used to establish a communication connection with the electronic device 10, the first control unit 101 can determine that the received service request message is the target service request message.

In a possible implementation manner, the service information includes: at least one of: service name information and service device identification information.

That is, when the service information includes the name information of the service, it means that the service request message contains the name of the service requested by the target device. At this time, the first control unit 101 can determine whether the service requested by the target device 20 is a service that the electronic device 10 can provide according to the name information of the service in the service request message. When the name information of the service in the service request message matches the service that the electronic device 10 can provide, it can be determined that the service request message is a target service request message. At this time, the first control unit 101 needs to respond to the target service request message, the first control unit 101 obtains the target data from the second storage area, and can send the target data as a response message to the target device 20. Alternatively, if the name information of the service in the service request message does not match the service that the electronic device 10 can provide, it means that the service request message is not a target service request message, and the first control unit 101 does not need to respond to it. In other possible implementations, when the first storage unit is a storage area that the first control unit 101 can access when the electronic device is in low power consumption mode, the first control unit 101 can also directly obtain the target data from the first storage area, and the embodiment of the present application is not limited to this.

Alternatively, when the service information includes the device identification information of the service, the first control unit 101 may determine whether the service request message is a target service request message based on the device identification information of the service in the service request message. In some embodiments, the first control unit 101 may determine whether the service message is a target service request message by detecting whether the device identification information of the service in the service request message is the identification information of the electronic device 10. If the device identification information of the service in the service request message is the identification information of the electronic device 10, the first control unit 101 determines that the received service request message is a target service request message, and the first control unit 101 needs to respond to the service request message. At this time, the first control unit 101 can obtain the target data from the second storage area. Otherwise, the first control unit 101 determines that the received service request message is not a target service request message, and the first control unit 101 does not need to respond to it.

As a possible implementation, the device identification information of the service may include at least one of the name information of the device and the service name information of the device. That is, the device identification information of the service may be the name information of the device, or the service name information registered by the device in the target service, or other information of the device that can uniquely identify the device, which is not limited in this application.

When the device identification information of the service includes the name information of the device, the first control unit 101 can detect whether the name information of the device contained in the service request message is the name information of the electronic device 10 when receiving the service request message. If the name information of the device contained in the service request message is the name information of the electronic device 10, it is determined that the received service request message is a target service request message. At this time, the first control unit 101 needs to respond to the target service request message, and the first control unit 101 can obtain the target data from the second storage area and send the target data to the target device 20.

Alternatively, if the device name information included in the service request message is not the name information of the electronic device 10, the first control unit 101 may determine that the received service request message is not the target service request message, and the first control unit 101 does not respond to the service request message.

When the device identification information of the service includes the service name information of the device, the first control unit 101 can detect whether the service name information of the device contained in the service request message is the service name information registered by the electronic device 10 in the target service when receiving the service request message. If the service name information of the device contained in the service request message is the service name information of the electronic device 10, it is determined that the received service request message is a target service request message. At this time, the first control unit 101 needs to respond to the target service request message, and the first control unit 101 can obtain the target data from the second storage area and send the target data to the target device 20.

Alternatively, if the device service name information included in the service request message is not the service name information of the electronic device 10, it is determined that the received service request message is not the target service request message, and the first control unit 101 does not respond to the service request message.

As a possible implementation, when the electronic device 10 is an image forming device, the service name information includes at least one of a printer service, a scanning service, and a fax service. At this time, the first control unit 101 can detect the service name information contained in the service request message when receiving the service request message. If the service name information includes at least one of a printer service, a scanning service, and a fax service, it means that the received service request message is a target service request message for establishing a communication connection with the image forming device. At this time, the first control unit 101 can obtain the target data from the second storage area and send the target data to the target device 20.

Of course, the electronic device may also comprehensively determine whether the aforementioned service request message is the target service request information based on the device identification of the aforementioned service and the name information of the service, and the embodiment of the present application does not limit this.

As a possible implementation manner, the second control unit 102 is specifically used to: obtain target data, encapsulate the target data according to the data format of the target service, and store the encapsulated target data in the first storage area.

The target format is the data format corresponding to the target service.

The first control unit 101 is specifically used for: when the electronic device 10 is in low power consumption mode, if a target service request message sent by the target device 20 is received, network encapsulation is performed on the target data obtained in the second storage area, and the network encapsulated target data is sent to the target device 20.

That is, the target service has its own data format. When the electronic device 10 sends the target data to other devices, it needs to encapsulate the target data according to the data format of the target service, so that when other devices receive the target data, they can parse the target data according to the data format of the target service and obtain the relevant data of the electronic device 10 they need. Based on this, in order to reduce the computational complexity of the first control unit 101, after obtaining the target data, the second control unit 102 can first encapsulate the target data according to the data format of the target service, and then store the target data in the first storage area. In some embodiments, if the target data is only part of the data of the target service, when encapsulating the target data according to the data format of the target service, the second control unit 102 can also supplement the content that is not in the target data according to the data format of the target service. For example, the data format of the target service contains IP address information, name information, functional attribute information of the electronic device 10, and service name information of the electronic device 10. At this time, if the target data only includes the functional attribute information of the electronic device 10 and the service name information of the electronic device 10, when the target data is encapsulated according to the data format of the target service, the second control unit 102 needs to first obtain the IP address information and name information of the electronic device 10. The IP address information, name information, functional attribute information of the electronic device 10, and service name information of the electronic device 10 are encapsulated according to the data format of the target service. After the encapsulation of the target data is completed, the encapsulated target data is stored in the first storage area. At this time, before the electronic device 10 sends the target data to the target device, the first control unit 101 can obtain the encapsulated target data from the first storage area, and store the obtained target data in the second storage area.

When the electronic device 10 is in low power consumption mode, if a target service request message sent by the target device 20 is received, the first control unit 101 needs to send target data in a target format to the target device 20. At this time, the first control unit 101 can transmit the target data to the target device 20 through network transmission. Therefore, in order to be able to transmit the target data in the target format to the target device 20, the first control unit 101 needs to first perform corresponding network encapsulation on the target data in the target format, and then transmit the network-encapsulated target data to the target device 20 through the network. At this time, when the first control unit 101 performs network encapsulation on the target data in the target format, it can determine the data encapsulation format according to the transmission protocol it adopts, and then encapsulate the target data in the target format in a corresponding format.

In some embodiments, the first control unit 101 can perform network transmission of the target data through TCP (Transmission Control Protocol). At this time, the first control unit 101 can encapsulate the target data in the target format according to the data format of TCP to form a TCP data packet, and transmit the TCP data packet to the target device 20 through the network.

In some embodiments, the first control unit 102 may also perform network transmission of the target data via UDP (User Datagram Protocol). At this time, the first control unit 101 may encapsulate the target data in the target format according to the data format of UDP to form a UDP data packet, and transmit the UDP data packet to the target device 20 via the network.

Of course, the first control unit 101 can also perform network transmission of target data through other transmission protocols. At this time, the first control unit 101 can perform corresponding network encapsulation of the target data in the target format according to the transmission protocol, and the embodiment of the present application does not limit this.

As a possible implementation method, when the first control unit 101 needs to send the network-encapsulated target data to the target device 20, it can transfer the target data to the output interface of the electronic device 10 through DMA (Direct Memory Access), and send the encapsulated target data out through the output interface.

As a possible implementation method, since the target data encapsulated according to the data format of the target service needs to add information, the storage space occupied by the encapsulated target data will become larger. In order to reduce the occupancy of the storage space, the second control unit 102 may not encapsulate the target data according to the data format of the target service, but directly store the acquired target data in the first storage area. At this time, when the first control unit 101 needs to perform system initialization when the electronic device enters the low power consumption mode, the target data acquired from the first storage area is the target data that is not encapsulated according to the data format of the target service. The first control unit 101 stores the target data acquired from the first storage area in the second storage area. When the electronic device 10 is in the low power consumption mode, if a target service request message is received and a response is required through the target data, the first control unit 101 needs to first encapsulate the target data according to the data format of the target service and then send it. That is, the first control unit 101 is specifically used to encapsulate the target data obtained in the second storage area according to the data format of the target service to obtain the target data in the target format if a target service request message is received from the target device 20 when the electronic device 10 is in the low power consumption mode; perform network encapsulation on the target data in the target format, and send the network encapsulated target data to the target device 20.

In an embodiment of the present application, when the electronic device 10 is in low power consumption mode, if the first control unit 101 receives a target service request message sent by the target device 20, the first control unit 101 needs to obtain the target data from the second storage area. Since the target data is data that is not encapsulated according to the data format of the target service, in order for the target device 20 to correctly parse the target data, the first control unit 101 needs to first encapsulate the target data according to the data format of the target service to obtain the target data in the target format. Since the target data in the target format needs to be transmitted to the target device 20 via the network, the first control unit 101 also needs to perform network encapsulation on the target data in the target format according to the network transmission protocol, and transmit the encapsulated target data to the target device 20 via the network.

In some embodiments, the target service may be a Bonjour service. In this case, the target data is the data of the Bonjour service. That is, the target data is the data that the electronic device 10 needs to send to other devices when the other devices establish a communication connection with the electronic device 10 through the Bonjour service.

In this way, in an embodiment of the present application, when the electronic device 10 is in a low power consumption mode, it can also respond to the target service request message so that the target device 20 can establish a communication connection with the electronic device 10 through the target service, thereby achieving the purpose of meeting the low power consumption requirements of the electronic device 10 while also establishing a communication connection with the target device 20 through the target service.
