detailed description

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, but not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

As shown in FIG. 1 , the current SAE system architecture in 3GPP can implement management of background traffic resources. The system includes an Evolved UMTS Territorial Radio Access Network (E-UTRAN) for implementing functions related to the wireless evolved network. The Mobility Management Entity (MME) is responsible for the mobility management of the control plane, such as user context and mobility state management, and assigning user temporary identity. A Serving Gateway (S-GW) is a user plane anchor between 3GPP access networks. A packet data network gateway (PDN GW, P-GW) is a user plane anchor between a 3GPP access network and a non-3GPP access network, and an external packet data network (PDN, Packet Data Network). )Interface. Policy and Charging Rule Function (PCRF) for policy control rule formulation and flow-based charging. The Home Subscriber Server (HSS) is used to store user subscription information. User Equipment (UE), a user terminal device that interacts with the user plane through the E-UTRAN and the SAE. UMTS Terrestrial Radio Access Network (UTRAN, UMTS Terrestrial Radio Access Network), GSM/EDGE Radio Access Network (GERAN), used to implement all wireless-related functions in existing GPRS/UMTS networks. The Serving GPRS Supporting Node (SGSN) is used to implement functions such as routing and forwarding, mobility management, session management, and user information storage in the GPRS/UMTS network.

In addition, industry users (which may be users of government-enterprise-related industries) use their application servers (ie, the three-party server in the figure) to connect with the carrier network through the operator's network capability open layer. The RPSF (the RP payload schedule function) is connected to the mobility management element (Policy and Charging Rule Function) through the Np interface, and is connected to the mobility management network element through the Nq interface. The RPSF is used for collecting, analyzing, and predicting network status information (real-time information and historical information), and supports resource scheduling and load control for access services (such as background traffic services) of the application server. The network capability open layer connects the internal network element of the operator to the external application server to implement the opening of the carrier network capability. The application server can be a three-party server, such as a government, public security, fire, traffic, or other enterprise dedicated server.

Many user terminals within a user group under one application server may have the same background traffic download requirements. The background traffic downloading in the embodiment of the present invention may be an upgrade terminal application, an update terminal database, and the like. Since most background traffic download services are non-emergency communication requirements, they do not require strong real-time performance, so they can be performed during network idle periods. By way of example, the process is as follows:

1. The user terminal sends a background traffic download request to the application server, and the application server forwards the request of the user terminal to the network, and the application server can provide the expected background traffic size and the expected download time.

2. The PCRF formulates a background traffic downloading policy for the user terminal, including: an allowed background traffic download time window (time window), a maximum allowed rate, and a corresponding charging policy.

3. The application server requests to enable the background traffic service for the user terminal, and the PCRF determines the background traffic download for the user terminal according to the established background traffic download policy. Policy and billing control.

4. Finally, the policy and charging control execution device allocates bearer resources for the background traffic download of the user terminal according to the policy and charging control, so that the application server can transmit data for the user terminal.

Generally, in a region, there are many user terminals that need to download background traffic, and the PCRF will formulate a background traffic download policy for each user terminal. The data requested by each user terminal may be the same, and the time window of the request may be the same. This means that the PCRF needs to respond repeatedly (develop multiple multiple background traffic download strategies) and increase network overhead. In addition, if the download time windows determined by the network side for each user terminal are the same, the network side simultaneously initiates background traffic transmission to each user terminal. If there are a large number of user terminals in the adjacent area, and the network side transmits data to each user terminal at the same time, it is likely to cause congestion of the network in the area.

The method provided by the embodiment of the present invention aims to prevent the PCRF from repeatedly responding to requests from the application server while avoiding network congestion caused by the background traffic download service.

Example 1:

The embodiment of the invention provides a background traffic downloading method, and the execution entity is an application server. As shown in FIG. 2, the method includes the following steps:

101. The application server obtains the requirement information of the user group for background traffic download.

The requirement information includes: X location areas corresponding to each user terminal in the user group, IP addresses of user terminals in each of the X location areas, and at least the following information. One: a time window required for the user group to perform background traffic download, and a maximum bandwidth required for the user group to perform background traffic download. The user group is a user group that needs to perform background traffic download among a plurality of user groups corresponding to the application server. At least one user terminal is included in the user group. And multiple users or all users in the user group will receive background traffic from the application server. The background traffic may be system information of the group application, may be periodic information that the group user subscribes to, or may be any type of information with the same content.

It should be noted that any one of the X location areas is a range of areas selected by the application server to provide services under the background traffic, and may be a GPS coordinate location area or other information that can express the location. One location area corresponds to one or more of an operator defined tracking area, an area covered by an evolved base station eNB, a routing area, and a cell. That is to say, the user group corresponds to X location areas, but does not necessarily correspond to X carrier location areas.

In the prior art, the network-side policy-making unit creates a background traffic download policy for the user terminal that initiates the background traffic download request. In fact, the background traffic download request of each user terminal in a group may be the same, thus causing the network. The policy-making unit on the side responds repeatedly to the same request, and generates a background traffic download policy multiple times, which increases network overhead. In the background traffic downloading method provided by the present invention, the application server determines a demand message for the group to perform background traffic download, so that the network-side policy making unit formulates a background traffic downloading policy for the group, and avoids the network-side policy-making unit to the same Requesting a repeated response saves network overhead.

The present invention utilizes the policy and charging device to formulate a background traffic downloading policy for the user group. It is noted that the policy and the charging device cannot know the region corresponding to the user group, so the application server needs to determine the corresponding user group. The area information of each area, so that the policy and charging setting device generates a background traffic downloading policy for each area of the user group. The policy and accounting setting device in the implementation of the present invention may be a policy and charging determining unit PCRF, which is not limited herein.

102. The application server generates a background traffic download request that carries the requirement information, and sends the background traffic download request to an open platform.

The open platform may be an open platform of an operator (the network capability open layer Exposure layer), and implement communication between the application server and the operator network. The open platform may have a protocol conversion function, and may convert a protocol from an interface in the operator domain with a protocol of an interface used by an external server (for example, an application server described in the embodiment of the present invention).

103. The application server receives a response message sent by the policy and the charging and formulating device, and obtains a policy identifier included in the response message.

Here, the policy and charging setting device is only one of a plurality of policy and charging setting devices corresponding to the user group. Since the device performs the same action for the respective policy and charging, the application server receives the response message. Here is a description of a policy and billing device. In addition, the policy identifiers in the response message may be the same or different, because the policy and the charging device may have the same background traffic downloading policy as the corresponding operator location area. Not the same. If the background traffic download policy of each operator location area is the same, the policy identifier of each background traffic download policy is also the same. Corresponding to the application server, the policy identifier obtained in the response message sent by the policy and the accounting device is the same.

Generally, the user terminals in one user group correspond to X location areas, and the X location areas may correspond to Y carrier location areas, and the Y operator location areas may correspond to Z policy and charging formulating devices, and each policy The charging device sends a response message to the application server, so the application server may receive multiple response messages. For example, if the user group corresponds to three location areas, the three location areas correspond to four carrier location areas (the one location area corresponds to two operator unknown areas), and the four operator location areas correspond to two strategies. With the billing device, if the application server currently only requests the background traffic download service for the user group, the application server will receive two response messages, which are respectively sent by the two policies and the accounting device. It should be noted that, in the implementation of the present invention, a response message of a policy and a charging formulation device is used for explanation.

The application server sends a bearer setup request to the policy and charging execution device, so that the policy and the charging execution device initiates the policy and charging according to the background traffic download policy corresponding to the policy identifier in the response message. The background traffic download service of each user terminal in the operator location area corresponding to the device is set; the bearer setup request carries the policy identifier in the response message.

Here, the application server sends the policy identifier in the response message to the policy and charging execution device, where the policy and the charging execution device can initiate the policy and charging according to the background traffic download policy corresponding to each policy identifier. Develop equipment-specific operations The background traffic download service of each user terminal in the merchant location area.

In a specific implementation, the policy and the charging device may generate the policy and charging control of each operator's location area according to the background traffic downloading policy of each operator's location area, and then implement the policy and charging control of each operator's location area. The corresponding policy identifier is sent to the policy and charging execution device. The application server sends a bearer setup request to the policy and the billing execution device, and the policy and the billing execution device initiates the policy and the billing control device according to the policy and the billing control corresponding to the policy identifier in the bearer setup request. The background traffic download service of the user terminal in the location area.

In the embodiment of the present invention, the response message may or may not include timing information, which is determined by a policy and a charging setting device that sends the response message. The response message includes the timing information, indicating that the policy for sending the response message fails to generate the background traffic download policy for the first background traffic download in one or more carrier location areas in the operator location area corresponding to the billing device. If the response message does not include the timing information, it indicates that the policy and the accounting device that sends the response message can generate a background traffic download policy for each corresponding carrier location area.

Preferably, in a preferred embodiment of the present invention, before the application server acquires the policy identifier included in the response message, the method further includes:

The application server determines whether the response message includes timing information.

Preferably, in a preferred embodiment of the invention, the method further comprises:

If the response message includes timing information, it is determined whether the response message includes area information.

If it is determined that the response message includes the area information, send a background traffic download request to the open platform, requesting to establish a background traffic download service for the operator location area corresponding to the area information; and to the policy and charging execution device Sending a bearer setup request, requesting the user terminal corresponding to the policy and the charging device, except the zone The user terminal outside the user terminal corresponding to the domain information starts the background traffic download service.

Here, the policy and billing device corresponding to the response message may correspond to multiple operator location areas, and the policy and charging device may generate an operator location for all (or part of) the plurality of operator location areas. The background traffic downloading policy corresponding to the area, for the operator location area where the background traffic downloading policy is generated, the policy and charging setting device carries a timing message in the response message sent to the application server, so as to inform the application server which carrier location The background traffic download policy generation for the zone failed.

For example, the policy and the charging device are used as the PCRF. If the application server receives the response message sent by the PCRF1, it includes a timing message, and the timing message includes the area message of the corresponding carrier location area 1. This indicates that the background traffic downloading policy for background traffic downloading in the operator location area other than the operator location area 1 is successfully generated in the multiple carrier location areas corresponding to the PCRF1. The time window is included in each background traffic downloading strategy. It is assumed that the time windows in each background traffic downloading policy are the same, and the application server can send a background traffic download request to the open platform within the time window, and again request to establish a background traffic download service for the operator location area 1. At the same time, the bearer setup bearer request is sent to the core network, and all the user terminals except the user terminal corresponding to the operator location area 1 request to establish a bearer in each user terminal in the user group that needs to download the background traffic.

In addition, if the application server receives the response message A sent by the PCRF1, it includes a timing message, and the timing message does not include the area message of its corresponding carrier location area. In this way, the application server cannot know which carrier location areas in the operator location area corresponding to the PCRF1 have failed to generate the background traffic download policy for background traffic download. The application server needs to send a background traffic download request to the open platform, and request to establish a background traffic download service for each operator location area corresponding to the PCRF1 (that is, each operator location area corresponding to the response message A).

Preferably, in a preferred embodiment of the present invention, after the application server determines that the response message includes area information, the method further includes:

The application server monitors the movement of the user terminal in the operator location area corresponding to the area information.

Generally, for a policy and charging device, the application server sends a bearer setup request to the policy and charging enforcement device, where the bearer setup request includes the IP of each user terminal in the operator location corresponding to the policy and the charging device. The address, the request policy, and the charging execution device start the background traffic downloading service of each user terminal in each operator location area corresponding to the policy and the charging setting device. The application server may simultaneously transmit data to each user terminal in the operator location corresponding to the policy and charging setting device. If the bearer setup request includes the IP address of each user terminal that needs background traffic downloading in the operator location corresponding to the billing-making device, the policy and the charging execution device initiates the policy corresponding to the billing-making device. The background traffic download service of each user terminal that needs to perform background traffic download in each operator location area. The application server simultaneously transmits data to each user terminal that needs background traffic downloading in the operator location corresponding to the policy and charging setting device, which can alleviate network congestion to a certain extent.

Or the application server acquires a unit traffic value required for background traffic downloading by a single user terminal in the user group, and a number of user terminals in the user group, and the unit traffic value and the user group. The product of the number of user terminals in the user is used as the maximum bandwidth required for the background traffic download by the user group, wherein the bandwidth required for each user terminal to perform background traffic download is the same.

In addition, the location area determined by the application server may be the area of the area where the application server provides the background traffic information download service, and may be a GPS coordinate area or other form that can express the location information, which is not limited herein. One location area corresponds to one or more of an operator defined tracking area, an area covered by an evolved base station eNB, a routing area, and a cell. In this way, X location areas do not necessarily correspond to X operators. Location location area.

502. The application server generates a background traffic download request that carries the requirement information, and sends the background traffic download request to the open platform.

The background traffic download request includes requirement information of the user group for performing the first background traffic download. Generally, the RPSF is connected to the MME (Mobility Management Entity), because the MME is responsible for mobility management of the control plane, such as user context and mobility state management, and assigning the identity of the user. The PCRF is not connected to the MME. Therefore, the identity information of the user in the group cannot be perceived, and the area information of the carrier location area corresponding to the group cannot be perceived. In a system without RPSF, the PCRF needs to set the background traffic download for the group, and the application server needs to send the user group's background traffic download request information to the open platform through the background traffic download request, so that the open platform will locate the user group. Map to the carrier location area.

In addition, if the application server obtains the IP addresses of the user terminals that need to perform background traffic download in each of the X location areas after the step 501, the background traffic download request needs to carry the needs in each location area. Download the IP address of each user terminal of the background traffic.

The open platform is a platform for connecting the operator network element and the external third-party server in the operator domain. The platform may have a protocol conversion function, and can convert the protocol from the interface of the operator domain with the protocol of the interface used by the external server.

503. The open platform receives a background traffic download request sent by the application server.

The background traffic download request includes a time window required for the user group to perform background traffic downloading and demand information for the user group to perform background traffic download.

504. The open platform maps the X location areas into Y carrier location areas, and acquires network status information of each of the Y carrier location areas.

The network status information of the operator location area includes: the number of user terminals in the carrier location area that need to perform background traffic downloading, and the maximum total bandwidth of the operator location area.

If the application server also acquires each of the X location areas after step 501 The IP address of the user terminal that needs to perform the first background traffic download in the location area, and the background traffic download request received by the open platform carries the IP address of the user terminal in each location area that needs to perform the first background traffic download. Then, the open platform here also needs to obtain the IP address of the user terminal that needs to perform the first background traffic download in each operator location area.

It should be noted here that one location area corresponds to one or more of the tracking area defined by the operator, the area covered by the evolved base station eNB, the routing area, and the cell. Therefore, the X location areas do not necessarily correspond to the X operator location location areas. For example, in step 501, the application server determines that the user group corresponds to four location areas, and if one of the location areas corresponds to two carrier location areas, and the other three location areas respectively correspond to one carrier location area, the user group It corresponds to 5 operator location areas.

In addition, for each operator location area, the open platform also needs to determine the maximum total bandwidth of the operator location area and the number of user terminals corresponding to the user group in the carrier location area that need to download background traffic. In a specific implementation, the open platform maps each location area information to a corresponding operator location, generates an operator location information list, and counts the number of user terminals that need to be in the background traffic in each operator location area in the list (user group) The corresponding user terminal of the group) and the maximum total bandwidth in the area. Since the background traffic download request received in step 503 carries the IP address of the user terminal that needs to download the background traffic in each of the X location areas, the open platform maps the X location areas corresponding to the user group into Y operations. When the location area is located, the IP address of the user terminal that needs to download background traffic in each operator location area can be obtained accordingly.

In addition, if the requirement information of the user group determined in step 501 includes the maximum bandwidth required for the user group to perform background traffic download, and the maximum bandwidth is the number of user terminals in the user group that need to download background traffic, and a single user terminal. The two parameters required for the first background traffic download are determined. Here, for an operator location area, the open platform may use, as the operator, the product of the bandwidth required for the single user terminal to download the background traffic and the number of user terminals in the carrier location area that need to download the background traffic. The maximum total bandwidth of the location area. Of course, the operator The obtaining of the maximum total bandwidth of the location area is not limited thereto. If the status information of the user group determined in step 501 does not include the traffic value of the user group download background traffic, the open platform may also determine the maximum location area of each operator. Total bandwidth.

505. The open platform determines Z PCRFs corresponding to Y operator location areas.

Specifically, the corresponding PCRF can be determined by confirming the PCRF domain information. The PCRF domain information may be the domain ID of the operator. In the routing process of the PCRF, the open platform may determine the corresponding PCRF by using a DRA (Diameter Routing Proxy) or according to the domain identifier of the operator corresponding to the operator's location area.

Here, one PCRF may correspond to multiple operator location areas, so the Y carrier location areas do not necessarily correspond to Y PCRFs. For example, if the user group corresponds to the four carrier location areas, respectively, A, B, C, and D, where the operator location areas A and B correspond to PCRF1, and the operator location areas C and D correspond to PCRF2.

506. The open platform sends the network state information of each of the operator location areas to the PCRF corresponding to the operator location area, and sends the PCRF to the Z PCRFs. The time window required to send a user group for background traffic download.

As described in step 505, the open platform needs to send the network status information of the operator location areas A and B to the PCRF1, and send the network status information of the operator location areas C and D to the PCRF2.

Here, since the requirement information that the step 501 has defined the first background traffic download by the user group includes the time window required for the first background traffic download, the open platform sends the network status information of each operator location area to the In addition to the PCRF corresponding to the location area of the carrier, the time window required for the download of the first background traffic needs to be sent to each PCRF, so that each PCRF determines whether the time window required for the first background traffic download can satisfy the location area of each carrier. Background traffic download request.

In addition, if the open platform obtains the IP address of the user terminal that needs to perform the first background traffic download in each operator location area in step 504, the open platform also needs to perform the first in each operator location area. The IP address of the user terminal that is downloaded by the background traffic is sent to the PCRF corresponding to the location area of the carrier.

507. The PCRF1 receives network status information of each operator location area corresponding thereto, and a time window required for the user group to perform background traffic download.

Here, for convenience of understanding, PCRF1 in the Z PCRFs corresponding to the Y operator location areas is taken as an example, and a specific procedure flow corresponding to the PCRF as the execution subject in the method of the present invention is introduced.

508. For an operator location area corresponding to the PCRF1, the PCRF1 determines whether the network status in the operator location area meets the background traffic download request of the carrier location area in the time window required for the user group to perform background traffic downloading. .

If it is determined that the background traffic download request of the operator location area is satisfied, step 509 is performed; if it is determined that the background traffic download request of the carrier location area is not satisfied, step 510 is performed.

509. The PCRF1 generates a background traffic download policy of the operator location area according to the network status information of the operator location area, and generates a policy identifier of the background traffic download policy.

The policy identifier may further include identifier information of the user group. Since the application server may correspond to multiple groups, the background traffic download service may be requested for multiple groups. Therefore, the determined policy identifier of the background traffic download policy may further include the group identification information.

510. The PCRF1 generates timing information corresponding to the location area of the operator.

If the response message sent by the PCRF1 to the application server further carries the area information of the operator location area corresponding to the timing information, the application server may be notified of which carrier location area's background traffic download policy generation fails.

The response message sent by the PCRF1 to the application server may not carry the area information of the operator location area corresponding to the timing information, so that the application server cannot know which carrier location downloading background background traffic downloading policy fails. The background traffic download service is re-requested to the open platform for all the operator location areas corresponding to the PCRF1.

511. For the remaining operator location areas corresponding to PCRF1, PCRF1 performs steps 508-510.

In this way, PCRF1 generates a background traffic download policy or a timing information for each carrier location area corresponding thereto. For example, if the PCRF1 corresponds to three carrier location areas, the background traffic download policy of one of the operator location areas fails to be generated, and the background traffic download policies of the other two operator location areas are successfully generated, so that the PCRF generates a timing information. Two background traffic download strategies.

512. The PCRF1 sends a response message to the application server through the open platform.

If the PCRF1 generates a background traffic download policy for each of the corresponding operator location areas, the response message includes: a policy identifier of the background traffic download policy of each operator location area corresponding to the PCRF.

If there is an operator location area in which the background traffic download policy fails to be generated in the operator location area corresponding to the PCRF1, the response message includes: a policy identifier of the background traffic download policy and timing information; or a policy of the background traffic download policy Identification, timing information, and area information corresponding to the timing information. For example, if the PCRF1 corresponds to the three carrier location areas, the background traffic download policy of one of the operator location areas fails to be generated, and the background traffic download policies of the other two carrier location areas are successfully generated, so that the response message sent by the PCRF1 includes : A timing message, and a policy identifier for two background traffic download policies.

Each of the PCRFs performs steps 507-512, and the application server can receive the response message corresponding to each PCRF. Here, it should be noted that the allowed download time window in the background traffic download policy formulated by each PCRF may be the same time window.

It should be noted that if the application server sends the background traffic download request to the open platform, the IP address of each user terminal that needs to download the background traffic in each location area needs to be carried, and the open platform acquires the needs in each operator location area. The IP address of the user terminal that downloads the background traffic. When the PCRF sends a response message to the application server through the open platform, the open platform converts the IP address of the user terminal that needs to perform background traffic download in each operator location area. The IP address of the user terminal that needs to perform background traffic download in each location area, so that the application server requests the user terminal in each location to request the bearer resource.

513. The application server determines whether the response message includes timing information.

It should be noted that the method for analyzing the response message of each policy and the accounting device is the same as that of the application server. For the sake of easy understanding, the response message sent by the PCRF1 is taken as an example.

The application server determines whether the timing information is included in the response message. The status information of the user group determined in step 501 includes a time window required for the user group to perform background traffic downloading. Therefore, each PCRF determines whether the background of each operator location area is met. Traffic download request. If the PCRF cannot meet the background traffic download request of a certain operator's location area, the application server needs to re-request the background traffic download service for the carrier location area. In addition, the application server may determine, by using the timing information in the response message, whether there is an operator location area where the background traffic download policy generation fails.

If it is determined that there is no response message in the response message, proceed to step 514; if it is determined that the time information exists in the response message, proceed to step 515.

514. The application server acquires a policy identifier in the response message, and sends a bearer setup request to the policy and charging execution device.

The bearer setup request carries a policy identifier in the response message.

Here, the policy and charging execution device receives a bearer setup request sent by the application server, and starts the operation corresponding to the policy and billing device (PCRF1) according to the background traffic download policy corresponding to the policy identifier in the response message. The background traffic download service of each user terminal in the merchant location area.

In addition, the bearer setup request may include an IP address of the user terminal that needs to perform the background traffic download in each user terminal corresponding to the PCRF1, so as to request that the policy and the charging execution device are each user terminal corresponding to the PCRF1, The user terminal that downloads the background traffic starts the background resource download service. Generally, the bearer setup request includes the IP addresses of all user terminals in the operator location area corresponding to the PCRF1. Therefore, the application server may simultaneously transmit data to each user terminal corresponding to the PCRF1, which may cause network congestion. If the bearer setup request includes the IP address of the user terminal that needs to perform the background traffic download in each user terminal corresponding to the PCRF1, the application server only needs to perform the user terminal of the background traffic download in each user terminal corresponding to the PCRF1. Transmitting data can alleviate network congestion to a certain extent.

The premise of the step 514 is to determine that there is no timing information in the response message, that is, in the operator location area corresponding to the PCRF1, there is no operator location area where the background traffic download policy generation fails, because the user group corresponds to the Y carriers. In the location area, a total of Y policy identifiers are included in each response message received by the application server.

515. The application server sends a background traffic download request to the open platform, requesting to establish a background traffic download service for the operator location area corresponding to the area information, and sending a bearer setup request to the policy and the charging execution device, where the request is PCRF1. In the corresponding user terminal, the user terminal other than the user terminal corresponding to the area information starts the background traffic download service.

Here, the application server needs to re-request the background traffic download service for the operator location area corresponding to the timing information (that is, the operator location area where the background traffic download policy is generated fails, which may be multiple). At the same time, the application server needs to send a bearer setup request to the policy and charging execution device for the operator location area (ie, the operator location area where the background traffic download policy is successfully generated). In the corresponding user terminal, all the user terminals except the user terminal corresponding to the area information start the background traffic download service.

Of course, the timing information may not include the area information, and the application server sends a background traffic download request to the open platform, and requests to establish a background traffic download service for each user terminal corresponding to the charging and setting device.

This is because the response message sent by the PCRF1, if only the timing information does not include the area information, the application server cannot determine which carrier location downloading area of the operator location area in the corresponding location area of the PCRF1 fails. Therefore, it is necessary to re-download the request to the open platform background traffic, and request the background traffic download service for all the operating location areas corresponding to the PCRF1.

The background traffic downloading method, device and system provided by the embodiment of the present invention, the application server determines the demand information of the user group, and sends a background traffic download request carrying the demand information to the open platform. The open platform determines an operator location area corresponding to the user group and a policy and charging device, and each operator location area The network state information of the domain is sent to the policy and charging device corresponding to the carrier location area, so as to formulate a background traffic downloading policy of the carrier location area. In the prior art, the application server forwards the background traffic download request of each user terminal in the group to the policy and charging device, and the policy and charging device generates background traffic for each user terminal in the group. Download strategy. The network side of the present invention sets a background traffic downloading policy for each operator location area corresponding to the user group, and does not need to formulate a background traffic downloading policy for each user terminal in the group, that is, avoiding the network side from the same type of application server. Request a duplicate response. In addition, the application server determines the IP address of the user terminal in the group that needs to download the background traffic, so that the request policy and the charging execution device initiates the background traffic download policy for the user terminal that needs to download the background traffic, and finally the application server needs to download the background traffic. The user terminal transmits data. Avoid network congestion due to simultaneous transmission of data to each user terminal in the group.

Example 3:

The present invention also provides a background traffic downloading method, which is different from the method provided in Embodiment 2:

After step 515, the following steps are further included:

516. The application server further monitors the movement of the user terminal in the operator location area corresponding to the area information.

517. The application server deletes the timing information, and determines that the operator area corresponding to the area information needs to be downloaded, when the number of the user terminals whose location changes is greater than the preset value in the operator area corresponding to the area information. The user terminal of the background traffic is configured to request the background traffic download service for the user terminal that needs to download the background traffic in the operator area corresponding to the area information.

The background traffic downloading method, device and system provided by the embodiment of the present invention, the application server determines the demand information of the user group, and sends a background traffic download request carrying the demand information to the open platform. The open platform determines an operator location area corresponding to the user group and a policy and charging device, and sends network status information of each operator location area to a policy and charging device corresponding to the operator location area. In order to develop a background traffic download strategy for the carrier's location area. Existing In the technology, the application server forwards the background traffic download request of each user terminal in the group to the policy and charging device, and the policy and charging device generates a background traffic download policy for each user terminal in the group. . The network side of the present invention sets a background traffic downloading policy for each operator location area corresponding to the user group, and does not need to formulate a background traffic downloading policy for each user terminal in the group, that is, avoiding the network side from the same type of application server. Request a duplicate response. In addition, the application server determines the IP address of the user terminal in the group that needs to download the background traffic, so that the request policy and the charging execution device initiates the background traffic download policy for the user terminal that needs to download the background traffic, and finally the application server needs to download the background traffic. The user terminal transmits data. Avoid network congestion due to simultaneous transmission of data to each user terminal in the group.

Example 4:

The embodiment of the present invention provides a background traffic downloading method, which is applied to a background traffic management system, where the background traffic management system includes: an application server, an open platform (an operator's network capability open layer exposure layer), an operation management device, and a policy. Develop equipment with billing. As shown in FIG. 7, the method includes the following steps:

601. The application server obtains the requirement information of the user group for background traffic download.

It should be noted that, in the fourth embodiment of the present invention, the policy and charging setting device is used as the policy and charging formulating unit PCRF as an example to describe the background traffic downloading method.

In addition, after determining that the user group performs the first background traffic downloading requirement information, the method further determines the IP address of the user terminal that needs to download the background traffic in each location area, so that the application server needs to download the background to the user group. The user terminal of the traffic sends data. Unlike the prior art, each user terminal in the default group of the application server needs to perform background traffic downloading, and then to each user group. The user terminal transmits data, which may cause network congestion.

In addition, the location area determined by the application server may be the area of the area where the application server provides the background traffic information download service, and may be a GPS coordinate area or other form that can express the location information, which is not limited herein. One location area corresponds to one or more of an operator defined tracking area, an area covered by an evolved base station eNB, a routing area, and a cell. Thus, the X location areas do not necessarily correspond to the X operator location location areas.

602. The application server generates a background traffic download request that carries the requirement information, and sends the background traffic download request to the open platform.

The background traffic download request includes a user group to perform first background traffic. Download the demand information. Generally, the RPSF is connected to the MME (Mobility Management Entity), because the MME is responsible for mobility management of the control plane, such as user context and mobility state management, and assigning the identity of the user. The PCRF is not connected to the MME. Therefore, the identity information of the user in the group cannot be perceived, and the area information of the carrier location area corresponding to the group cannot be perceived. In a system without RPSF, the PCRF needs to set the background traffic download for the group, and the application server needs to send the user group's background traffic download request information to the open platform through the background traffic download request, so that the open platform will locate the user group. Map to the carrier location area.

In addition, if the application server obtains the IP addresses of the user terminals that need to perform background traffic download in each of the X location areas after the step 601, the background traffic download request needs to carry the needs in each location area. Download the IP address of each user terminal of the background traffic.

603. The open platform receives a background traffic download request sent by the application server, and sends the background traffic download request to the operation management device.

604. The operation management device maps the X location areas into Y carrier location areas, and acquires network status information of each of the Y operator location areas.

If the application server obtains the IP address of the user terminal that needs to perform the first background traffic download in each of the X location areas after step 601, the background traffic download request received by the open platform carries each location area. The IP address of the user terminal that needs to perform the first background traffic download, then open the flat here. The station also needs to obtain the IP address of the user terminal that needs to perform the first background traffic download in each operator location area.

It should be noted here that one location area corresponds to one or more of the tracking area defined by the operator, the area covered by the evolved base station eNB, the routing area, and the cell. Therefore, the X location areas do not necessarily correspond to the X operator location location areas. For example, in step 601, the application server determines that the user group corresponds to four location areas, and if one of the location areas corresponds to two carrier location areas, and the other three location areas respectively correspond to one carrier location area, the user group It corresponds to 5 operator location areas.

In addition, for each operator location area, the open platform also needs to determine the maximum total bandwidth of the operator location area and the number of user terminals corresponding to the user group in the carrier location area that need to download background traffic. In a specific implementation, the open platform maps each location area information to a corresponding operator location, generates an operator location information list, and counts the number of user terminals that need to be in the background traffic in each operator location area in the list (user group) The corresponding user terminal of the group) and the maximum total bandwidth in the area. Since the background traffic download request received in step 603 carries the IP address of the user terminal that needs to download the background traffic in each of the X location areas, the open platform maps the X location areas corresponding to the user group into Y operations. When the location area is located, the IP address of the user terminal that needs to download background traffic in each operator location area can be obtained accordingly.

In addition, if the requirement information of the user group determined in step 601 includes the maximum bandwidth required for the user group to perform background traffic download, and the maximum bandwidth is the number of user terminals in the user group that need to download background traffic, and a single user terminal. The two parameters required for the first background traffic download are determined. Here, for an operator location area, the open platform may use, as the operator, the product of the bandwidth required for the single user terminal to download the background traffic and the number of user terminals in the carrier location area that need to download the background traffic. The maximum total bandwidth of the location area. Of course, the acquisition of the maximum total bandwidth of the operator location area is not limited thereto. If the status information of the user group determined in step 601 does not include the traffic value of the user group download background traffic, the open platform may also determine each carrier. The maximum total bandwidth of the location area.

605. The operation management device determines Z PCRFs corresponding to the Y operator location areas.

606. The operation management device sends the network status information of each of the Y operator location areas and the information of the Z policies and the charging establishment device to the open platform.

607. The open platform sends the network state information of each of the operator location areas to the PCRF corresponding to the operator location area, and sends the PCRF to the Z PCRFs. The time window required to send a user group for background traffic download.

As described in step 605, the open platform needs to send the network status information of the operator location areas A and B to the PCRF1, and send the network status information of the operator location areas C and D to the PCRF2.

Here, since the requirement information that the user group performs the first background traffic downloading in step 601 includes the time window required for the first background traffic download, the open platform sends the network state information of each operator location area to the In addition to the PCRF corresponding to the location area of the carrier, the time window required for the download of the first background traffic needs to be sent to each PCRF, so that each PCRF determines whether the time window required for the first background traffic download can satisfy the location area of each carrier. Background traffic download request.

In addition, if the open platform obtains the IP address of the user terminal that needs to perform the first background traffic download in each operator location area in step 604, the open platform also needs to perform the first in each operator location area. The IP address of the user terminal that is downloaded by the background traffic is sent to the PCRF corresponding to the location area of the carrier.

608. The PCRF1 receives network status information of each operator location area corresponding thereto, and a time window required for the user group to perform background traffic download.

609. For an operator location area corresponding to the PCRF1, the PCRF1 determines whether the network status in the operator location area meets the background traffic download request of the operator location area in a time window required for the user group to perform background traffic downloading. .

If it is determined that the background traffic download request of the operator location area is satisfied, step 610 is performed; if it is determined that the background traffic download request of the carrier location area is not satisfied, step 611 is performed.

610. The PCRF1 generates a background traffic download policy of the operator location area according to the network status information of the operator location area, and generates a policy identifier of the background traffic download policy.

611. The PCRF1 generates timing information corresponding to the location area of the operator.

612. For the remaining operator location areas corresponding to PCRF1, PCRF1 performs steps 609-611.

613. The PCRF1 sends a response message to the application server through the open platform.

Each of the PCRFs performs steps 608-613, and the application server can receive the response message corresponding to each PCRF. Here, it should be noted that the allowed download time window in the background traffic download policy formulated by each PCRF may be the same time window.

614. The application server determines whether the response message includes timing information.

The application server determines whether the timing information is included in the response message. The status information of the user group determined in step 601 includes a time window required for the user group to perform background traffic downloading. Therefore, each PCRF determines whether the background of each operator location area is met. Traffic download request. If the PCRF cannot meet the background traffic download request of a certain operator's location area, the application server needs to re-request the background traffic download service for the carrier location area. In addition, the application server may determine, by using the timing information in the response message, whether there is an operator location area where the background traffic download policy generation fails.

If it is determined that there is no response message in the response message, proceed to step 615; if it is determined that the time information exists in the response message, proceed to 616.

615. The application server acquires a policy identifier in the response message, and sends a bearer setup request to the policy and charging execution device.

The bearer setup request carries a policy identifier in the response message.

The premise of the step 615 is to determine that there is no timing information in the response message, that is, in the operator location area corresponding to the PCRF1, there is no operator location area where the background traffic download policy is generated, because the user group corresponds to the Y carriers. In the location area, a total of Y policy identifiers are included in each response message received by the application server.

616. The application server sends a background traffic download request to the open platform, requesting to establish a background traffic download service for the operator location area corresponding to the area information, and sending a bearer setup request to the policy and the charging execution device, where the request is PCRF1. In the corresponding user terminal, the user terminal other than the user terminal corresponding to the area information starts the background traffic download service.

Example 5:

The present invention also provides a background traffic downloading method, which is different from the method provided in Embodiment 4:

After step 616, the following steps are also included:

617. The application server further monitors the movement of the user terminal in the operator location area corresponding to the area information.

618. The application server deletes the timing information, and determines that the operator area corresponding to the area information needs to be downloaded, when the number of the user terminals whose location changes is greater than the preset value in the operator area corresponding to the area information. The user terminal of the background traffic is configured to request the background traffic download service for the user terminal that needs to download the background traffic in the operator area corresponding to the area information.

Example 6

The embodiment of the present invention provides a background traffic downloading method, which is applied to a background traffic management system, where the background traffic management system includes: an AS, an open platform (operator's network capability open layer exposure layer), PCRF1, PCRF2, and CN ( Core Network, core network). As shown in FIG. 8, the method includes the following steps:

701. The AS obtains a requirement information of the user group for background traffic downloading.

The requirement information includes X location areas corresponding to each user terminal in the user group, an IP address of each user terminal in each of the X location areas, and at least one of the following information. Item: a time window required for the user group to perform background traffic download, and a maximum bandwidth required for the user group to perform background traffic download. In this embodiment, the process information of the background traffic downloading method provided by the present invention is introduced by taking the time window required for the background traffic downloading by the user group as an example.

702. The AS sends the background traffic download request to the open platform.

First, the AS generates a background traffic download request, where the background traffic download request includes the demand information of the user group.

703. The open platform receives a background traffic download request sent by the AS, and determines a PCRF corresponding to the user group.

Here, it is assumed that the user group corresponds to two PCRFs, which are PCRF1 and PCRF2, respectively.

Specifically, the open platform first maps the X location areas corresponding to the user group into Y carrier location areas, and determines network status information of each of the Y operator location areas. Next, the Z PCRFs corresponding to the Y operator location areas are determined. In the present embodiment, it is assumed that Z is equal to 2.

704. The open platform sends network state information of the operator location area corresponding to the PCRF1 to the PCRF1.

705. The open platform sends network state information of the operator location area corresponding to the PCRF2 to the PCRF2.

706. PCRF1 and PCRF2 perform policy judgment.

Specifically, the specific steps of the above policy determination are introduced by taking PCRF1 as an example. The PCRF1 receives the network status information of each operator location area corresponding thereto, and the time window of the user group request.

For a carrier location area corresponding to the PCRF1, the PCRF1 determines whether the network status in the operator location area satisfies the background traffic download request of the operator location area within the time window requested by the user group.

In addition, if the PCRF1 determines that the network status in the operator location area does not satisfy the background traffic download request of the operator location area within the time window requested by the user group, the timing information is generated, and the operation may also be included in the timing information. The area information of the merchant location area, so as to inform the AS that the background traffic download policy generation of the operator location area fails.

707. PCRF1 and PCRF2 send a policy decision to the AS.

The policy decision sent by the PCRF contains the policy identifier of the background traffic download policy, and may also contain timing information.
