Description

Method, device and system for accessing WLAN by WiMo sending terminal

technical field

The present invention relates to the field of wireless communication, in particular to a method, device and system for a mobile terminal wireless multimedia transmission technology (WiMo) sending end to access a wireless local area network (WLAN).

Background technique

WiMo technology is a standard for point-to-point wireless audio and video transmission of mobile terminals. It can realize multi-screen sharing and interaction between mobile terminals and home TVs, projection devices, and display devices, and realize the "three screens in one" service experience centered on mobile terminals. As shown in Figure 1, WiMo technology realizes the wireless transmission of high-definition audio and video, and establishes a bridge between mobile terminals such as mobile phones and large-screen display devices such as TV screens.

In order to ensure interoperability, reduce equipment costs, and fully reuse the existing Wireless Fidelity (WiFi) infrastructure, the WiMo protocol is to reuse the WiFi Media Access Control (Mac) layer and the following protocols at the bottom layer.

In WiMo usage scenarios, mobile terminals such as mobile phones are generally used as WiMo transmitters, while large-screen display devices such as TV screens and their WiMo accessories are used as WiMo receivers. As shown in Figure 2, a typical WiMo system is described. It can be seen from Figure 2 that the WiMo technology communicates with the WiMo receiving end through the original WiFi chip of the mobile terminal. screen display, that is, the data displayed on the display screen of the WiMo sending end is displayed on the display screen of the WiMo receiving end synchronously.

Based on WiMo's existing working mode and system design ideas, in order to solve the problem that the existing WiMo sending end cannot use WiFi to access the Internet when it uses WiMo to realize the same screen display with the WiMo receiving end, WiMo sending is adopted in the existing WiMo solution. The end mixes WiMo and WiFi Internet access data. While establishing the connection for realizing the same screen display between the WiMo sending end and the WiMo receiving end, it also establishes the connection between the WiMo sending end and the WiMo receiving end for realizing the WiMo sending end accessing the Internet. Through the transfer of the WiMo receiving end, the relay transmission of WiFi Internet access data is realized, and the specific scheme can be shown in FIG. 3 .

In the actual application of WiMo, such as conference application, there is a scene where multiple users take turns to realize the same screen display on the same WiMo receiving end through their own WiMo sending end. It will exit the same-screen state (disconnect the connection with the WiMo receiving end to realize the same-screen display), but usually it will not disconnect the WiFi connection of the WiMo sending end to access the Internet, and continue to use the WiMo receiving end to connect to the Internet. When multiple users realize the same screen display of the WiMo sender and WiMo receiver, there will be discontinuous WiMo screens (frame skipping due to insufficient processing power), the core reason is that too many users use the WiMo receiver as Internet access The access point (AP) realizes the relay transmission of WiFi Internet data, which causes the Internet data to occupy too many processing resources of the WiMo receiving end, which affects the core function of the WiMo receiving end to realize the same screen display.

At present, the following solutions are mainly used to solve the above problems:

Use screen prompts to remind users to manually disconnect the WiFi connection between the WiMo sender and WiMo receiver to access the Internet after the end of the same screen display of the WiMo sender and WiMo receiver, and then choose to join other wireless local area networks (WLANs) that can access the Internet. ), but this solution is complicated for users to operate, and the user experience is poor;

To sum up, due to the WiMo point-to-point working mode, when there are too many users connected to the WiMo receiving end, the overload of Internet data will affect the stability of the data displayed on the same screen. If it is required to forcibly switch the WiFi connection of the WiMo sender that is in the state of exiting the same screen to access the Internet, the most feasible way is to manually switch, the user experience is not good, and it may be because some users forget to operate that the switch is not timely, resulting in the WiMo receiver. The cumulative load is too heavy, even paralyzing.

detailed description

It can be seen from the existing schemes that when the WiMo sending end uses WiMo to realize the same screen display with the WiMo receiving end, and at the same time accesses the Internet through the WiMo receiving end, the WiMo receiving end is simultaneously connected to two SSIDs that can be identified separately. Indicates the WLAN network. Assuming that the SSID of the WLAN network used to realize the same screen display with the WiMo sender is "WiMo", and the SSID of the WLAN network used to realize the WiMo receiver's access to the Internet is "Internet", then in the prior art, the device connection diagram can be As shown in Figure 4.

For the WiMo receiving end, it works in the AP mode in the network with the SSID "WiMo", and works in the client (client) mode in the network with the SSID "Internet". "The connection parameters of the WLAN network, the connection parameters include but are not limited to include: SSID information, authentication method, authentication parameters, the authentication parameters can be user name, password and so on.

In order to ensure that the user can disconnect the connection between the WiMo sending end and the WiMo receiving end for the same screen display, it can not only ensure the Internet connection, but also no longer occupy the processing resources of the existing WiMo receiving end, the core idea of the present invention is that the WiMo sending end When confirming normal communication between the WiMo receiving end and the WLAN network used for Internet access by the WiMo receiving end, when disconnecting the connection between the WiMo sending end and the WiMo receiving end for the same screen display, disconnect the WiMo sending end and the WiMo The WiFi connection between the receiving ends for accessing the Internet is automatically configured to access the WLAN network using the connection parameters from the WiMo receiving end, and the WLAN network is used to achieve Internet access, and the user realizes an automatic WLAN network without perception after finishing the same screen display connection scheme. A schematic diagram of device connection provided by the present invention may be shown in FIG. 5 .

Of course, the solution provided by the embodiment of the present invention is not only applicable to the scenario of realizing the same screen display through WiMo, but also applicable to other scenarios of the same screen based on WLAN or other specific data transmission applications.

The solutions of the present invention will be described below in conjunction with the accompanying drawings and various embodiments.

Embodiment one,

Embodiment 1 of the present invention provides a method for a WiMo sender to access a WLAN. The steps of the method may be shown in FIG. 6, including:

Step 101, the WiMo sender receives connection state information and connection parameters.

In this embodiment, while the WiMo sending end and the WiMo receiving end are displaying on the same screen, the WiMo receiving end can also be used to relay and access the Internet through the WLAN network built by the WiMo receiving end. In order to ensure that the WiMo sender can still access the Internet normally after disconnecting the WiFi connection between the WiMo receiver and the WiMo receiver for accessing the Internet, in this step, the WiMo receiver needs to send back to the WiMo sender the WiMo Connection status information and connection parameters of the WLAN network accessed by the receiving end to the Internet.

The connection status information is used to indicate whether the communication between the WiMo receiving end and the WLAN network is normal, which may be, but not limited to, whether the communication between the WiMo receiving end and the WLAN network is normal, or whether the communication between the WiMo receiving end and the WLAN network is normal. Communication between networks is abnormal. The connection parameters are parameters required for access authentication between the WiMo receiver and the WLAN network. The connection parameters include but are not limited to: the SSID, authentication method, and authentication parameters of the WLAN network. The authentication parameters may include usernames , password, etc.

Step 102, the WiMo sending end determines whether the connection state is a specified connection state.

In this step, the WiMo sending end judges the received connection state information to determine whether the WiMo receiving end communicates normally with the WLAN network, and if it is determined that the received connection state information indicates that the WiMo sending end and the The WLAN network connection is successful, that is, it is determined that the WiMo receiving end communicates normally with the WLAN network, and it is determined that the WiMo sending end has sent a request to disconnect the first connection to the WiMo receiving end, or has received a disconnection request sent by the WiMo receiving end. If the first connection request is opened, step 103 may be executed. Otherwise, if it is determined that the received connection state information indicates that the connection between the WiMo sending end and the WLAN network is unsuccessful, the connection state information of the WLAN network sent by the WiMo receiving end may be received again, and step 102 may be continued.

The WiMo receiving end sends the connection state information of the WLAN network again when the WiMo receiving end determines that the connection state information sent last time from the current moment indicates that the connection between the WiMo sending end and the WLAN network is unsuccessful. . It may also be that the WiMo sending end requests the WiMo receiving end to send again when it determines that the connection status information received last time from the current moment indicates that the connection between the WiMo sending end and the WLAN network is unsuccessful.

Of course, in this step, if the WiMo sending end determines that the received connection status information indicates that the WiMo sending end is successfully connected to the WLAN network, it may save the received connection parameters. And after saving the received connection parameters, continue to execute step 103 .

Step 103, the WiMo sending end disconnects the first connection and the second connection.

The first connection is a data and control connection between the WiMo sending end and the WiMo receiving end for realizing the same screen display, and the second connection is between the WiMo sending end and the WiMo receiving end Data connection for internet access. That is, in this step, the WiMo sending end simultaneously disconnects the connection with the WiMo receiving end for displaying on the same screen, and the WiFi connection with the WiMo receiving end for accessing the Internet.

Step 104, the WiMo sender sends a connection request to the WLAN network.

In this step, the WiMo sending end may send a connection request to the WLAN network according to the received connection parameters. Specifically, the WiMo sending end may actively search for and identify the WLAN network represented by the SSID in the connection parameter, and send a connection request to the corresponding AP.

Step 105, the WiMo sender performs access authentication with the WLAN network.

In this step, the WiMo sending end may perform access authentication with the WLAN network according to the received connection parameters. Specifically, the WiMo sending end may use the authentication parameters in the received connection parameters, such as user name and password, to perform access authentication with the WLAN network according to the authentication mode in the received connection parameters.

After the access authentication succeeds, step 106 can be continued, otherwise, this procedure can end.

Step 106, the WiMo sending end accesses the WLAN network.

After successful access authentication, the WiMo sending end may establish a WLAN data connection with the WLAN network, the data connection includes a connection from a physical layer to a network layer, and access the WLAN network.

Preferably, in this embodiment, in order to prevent the WiMo sending end from reconnecting to the WiMo receiving end, the connection parameters sent by the WiMo receiving end to the WiMo sending end may also include the AP corresponding to the WiMo receiving end. When the WiMo receiving end performs WLAN network access, it may be prohibited to access the WLAN network according to the AP corresponding to the WiMo receiving end. In this way, it is further ensured that the WiMo sending end does not affect the stability of the WiMo receiving end realizing same-screen display.

It should be noted that, in this embodiment, when disconnecting the connection between the WiMo sending end and the WiMo receiving end for the same screen display, it not only ensures the Internet connection, but also no longer occupies the processing resources of the existing WiMo receiving end. Therefore, this embodiment also includes a step of sending or receiving a request for disconnecting the first connection at the WiMo sending end, and this step may be performed before step 101:

Step 101', the WiMo sender sends or receives a request to disconnect the first connection.

In this embodiment, the request to disconnect the first connection may be initiated by the WiMo sending end, or may be in the mutual kick mode (that is, when there are other WiMo sending ends that need to realize the same screen display on the WiMo receiving end) ), initiated by the WiMo receiving end.

In this embodiment, after the WiMo sending end sends or receives the request to disconnect the first connection, the WiMo sending end receives the WLAN network connection status information and connection parameters sent by the WiMo receiving end, so that it can After the network is connected, access the WLAN network according to the received connection state information and connection parameters. Since the connection state information is received after the WiMo sending end sends or receives a request to disconnect the first connection, it can be guaranteed that the connection state information can reflect whether the WiMo receiving end and the WLAN network communicate normally at the current moment, according to the The connection state information realizes WLAN network access, which can effectively guarantee the success rate of WLAN network access.

Of course, in order to ensure the timeliness of WLAN network access, step 101' can also be performed after step 101 and before step 102:

That is, in this embodiment, the WiMo sending end may receive connection state information and connection parameters after the first connection and the second connection are established. And when sending or receiving a request to disconnect the first connection subsequently, the received connection state information and connection parameters may be used to access the WLAN network.

However, when step 101' is executed after step 101 and before step 102, the connection status information can reflect whether the current WiMo receiving end communicates normally with the WLAN network, and further improve the success rate of WLAN network access. After step 101', before step 102, further include step 102':

Step 102', the WiMo sender receives the connection status information again.

In this step, the WiMo sending end can receive the connection state information of the WLAN network sent by the WiMo receiving end again, so that the connection state information reflecting whether the current communication between the WiMo receiving end and the WLAN network is normal can be received.

Step 102' may be performed by the WiMo sender after performing step 101' and requesting the WiMo receiver to resend, or by the WiMo receiver actively resending after the WiMo sender performs step 101'.

For the WiMo receiving end, after sending a request for disconnecting the first connection to the WiMo sending end or receiving the request for disconnecting the first connection sent by the WiMo sending end, disconnect the first connection with the WiMo sending end.

Further, after step 102, the WiMo sending end determines that the connection status information indicates that the WiMo sending end is successfully connected to the WLAN network, and can send an indication message to disconnect the first connection to the WiMo receiving end, and the WiMo receiving end can be in When receiving the indication message, disconnect the first connection with the WiMo sending end.

Assuming that the connection status information determined by the WiMo sending end indicates that the WiMo sending end is successfully connected to the WLAN network, and it is determined that the WiMo receiving end communicates normally with the WLAN network whose SSID is "Internet", then the WiMo sending end can save the described WLAN network. connection parameters, and proceed to step 204.

Step 204, the WiMo sender sends an indication message.

In this step, the WiMo sending end can send an indication message to the WiMo receiving end, confirming that the received connection status information indicates that the WiMo sending end is successfully connected to the WLAN network (and the connection parameters have been saved), and instructing the WiMo receiving end to disconnect. Open the first connection, that is, disconnect the connection with the WiMo sender to realize the same screen display.

Step 205, the WiMo sending end disconnects the first connection and the second connection.

The WiMo sending end can disconnect the connection with the WiMo sending end to realize the same screen display as in the prior art. At the same time, in this step, it is also necessary to disconnect the WLAN network with the SSID "Internet" for accessing the Internet Since the connection is realized through the WLAN network with the SSID of "WiMo" and through the WiMo receiving end, in this step, the WiFi used to access the Internet is actually disconnected from the WLAN network with the SSID of "WiMo" connect.

At this time, the WiMo receiving end may disconnect the first connection. The WiMo receiving end disconnects the first connection, and the WiMo sending end disconnects the first connection and the second connection. It can be executed at the same time. It can be executed after the WiMo sending end disconnects the first connection and the second connection, or it can be executed before the WiMo sending end Disconnect the first connection and the second connection execution.

Step 206, the WiMo sender sends a connection request to the WLAN network.

In this step, the WiMo sender can send a connection request to the WLAN network whose SSID is "Internet" according to the SSID in the received connection parameters.

That is, the WiMo sender can actively search for and identify the WLAN network whose SSID is "Internet" in the connection parameters, and send a connection request to the corresponding AP.

Step 207, the WiMo sender performs access authentication to the WLAN network.

In this step, the WiMo sender performs access authentication with the WLAN network whose SSID is "Internet" according to the authentication information in the connection parameters, including but not limited to authentication mode and authentication parameters.

Step 208, the WiMo sender accesses the WLAN network.

After successful access authentication, the WiMo sender can establish a data connection with the WLAN network whose SSID is "Internet" and access the WLAN network.
