BRIEF DESCRIPTION OF THE DRAWINGS The technical solutions in the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative work are within the scope of the present invention.

Embodiment 1 of the present invention

A service control method is provided, which is mainly applied to a communication network system as shown in FIG. 1, and includes a radio access network, a service node, a gateway device, and a PCRF and an Application Function (AF) entity. The PCC architecture (only two devices in the PCC architecture are shown in Figure 1). The radio access network can access the user equipment to the network; the service node is mainly responsible for control plane functions such as routing forwarding and mobility management, in the general packet radio service technology (GPRS) or the universal mobile telecommunications system (Universal Mobile Telecommunications System) In the network of UMTS, the service node may be a Serving GPRS Supporting Node (SGSN), and in the wireless evolved network, the service node may include a Mobility Management Entity (MME); It is mainly responsible for data interaction with the user equipment and the uplink network device. In the wireless evolved network, the gateway device may include a Packet Date Network Gateway (PGW), and in the GPRS/UMTS network, the gateway device may be GPRS. The Gateway GPRS Support Node (GGSN); the PCC architecture can control and bill the data flows transmitted by the user equipment.

As shown in FIG. 2, the PCC architecture mainly includes a PCRF, a PCEF, a User Profile Repository (SPR), an application function entity, and a TDF. The PCRF is mainly based on an operator policy and accesses user equipment. The network policy is based on the restrictions of the network, the user subscription data, and the service information of the data stream currently being transmitted by the user equipment. The PCEF mainly performs the rules established by the PCRF to perform user plane detection and measurement on the data stream of the user equipment. In other words, the PCEF is set in a gateway device (such as a PGW or a GGSN) as a module of the gateway device, and the PCRF and the gateway device are connected through the interface Gx; the SPR mainly provides the user subscription data to the PCRF through the interface Sp; The AF entity dynamically provides application layer service information to the PCRF through the interface Rx. The TDF mainly performs content detection on the data stream of the user equipment, and reports the detection result to the PCRF through the Sd interface for policy decision. The TDF can be deployed in the gateway device. As a module in a gateway device (such as a PGW or GGSN). The PCC architecture may further include an online charging system and an offline charging system. The online charging system is respectively connected to the PCRF and the gateway device through the interface Gy, and the offline charging system is connected to the gateway device through the interface Gz.

The service control device in the PCC architecture, such as TDF or PCEF, or a gateway device (such as PGW or GGSN) that integrates TDF or PCEF functions, can perform service control according to the following steps. The flowchart is as shown in Figure 3, including:

Step 101: Receive a control policy for a data flow sent by a policy control and charging rule function entity PCRF, where the control policy includes type attribute information of the data flow and a corresponding control rule, where the type attribute information of the data stream includes data. The instance ID and/or instance-specific information of the stream, and the control rules corresponding to different types of data streams under the same service type are different.

The PCRF can actively trigger the process of the embodiment, and obtain the information required for the control policy corresponding to a certain user equipment, such as obtaining the user subscription information from the SPR, obtaining the service information from the AF entity, and formulating the control policy according to the information. The PCRF can also passively accept information of other devices, such as an AF entity or a gateway device, passively requesting the PCRF to formulate a corresponding control policy and then send it to a service control device such as TDF or PCEF. Or gateway devices to policy control the data flow.

In the control strategy, the type attribute information of the data stream refers to attribute information that distinguishes different types of data streams, and the control rules corresponding to the data streams of different service types are different, and the control rules of different types of data streams are different under the same service type. The different types of data streams can be distinguished by the unique information of the data stream, that is, the instance-specific information, or by the identifier that uniquely identifies the data stream, that is, the instance identifier, and the instance-specific information and the instance identifier are data. The type attribute information of the stream. For example, a file transfer protocol (FTP) service of a user equipment may use a destination address identifier of a data stream, such as a Uniform I Universal Resource Locator (URL), to distinguish different types of data streams under the FTP service. The destination address identifier is an instance of the data stream. Dedicated information; For a video service, the video coding rate of the data stream can be used to distinguish different types of data streams under the video service, and the video coding rate is instance-specific information of the data stream.

The control rule corresponding to a certain type of data stream refers to a parameter of the user equipment when transmitting the data stream of the type, and may generally include control information of quality of service (QoS) corresponding to the type of data stream, such as QoS. QoS Class Identifier (QCI), or Allocation and Retention Priority (ARP), or Maximum Bit Rate (MBR), or Guaranteed Bit Rate (GBR), etc. Parameters, and the control rules may also include parameter information such as network bandwidth.

Step 102: Perform corresponding policy control on the data flow of the user equipment according to the control policy received in step 101.

Specifically, if the control policy received in step 101 includes the first instance identifier of the data flow and the corresponding first control rule in the service type, the service control device performs the first control according to the first control. The rule controls the data flow indicated by the first instance identifier; if the control policy received in step 101 includes the first instance specific information of the data flow and the corresponding second control rule in a certain service type, the service control device When performing this step, it is determined whether the first instance specific information is included in the data flow of the user equipment, and if so, the data flow is controlled according to the second control rule; if the control policy received in step 101 includes a certain service If the second instance of the data flow, the second instance identifier, and the corresponding third control rule, the service control device determines whether the data stream indicated by the second instance identifier is included in the data flow. The second instance proprietary information, if any, controls the data stream or the like in accordance with a third control rule.

It can be seen that, when the service control is performed in the embodiment of the present invention, after receiving the control policy for the data flow sent by the PCRF, the service control device, such as the TDF or the PCEF or the gateway device, performs corresponding data flow on the user equipment according to the control policy. Policy control. In this embodiment, the type attribute information of the data stream and its corresponding control rule are included in the control policy, so that different types of data streams under the same service type can be controlled differently, and the control precision of the data stream is improved.

The service control process shown in FIG. 3 is a method in which the PCRF actively sends a control policy to control the data flow. In other specific embodiments, the service control process may also be triggered by the service control device, specifically, the service. The control device may perform the following steps 103 and 104 to trigger the process of the service control before performing the foregoing step 101. The flowchart is as shown in FIG. 4, and includes: Step 103: When receiving a data stream transmitted by the user equipment, determining a service type of the received data stream, and assigning an instance identifier to the received data stream and/or acquiring instance specific information of the received data stream, where the data stream The instance-specific information is information that distinguishes the data stream from other data streams, such as destination address or video encoding rate, and the instance identifier of the data stream refers to information that uniquely identifies the data stream.

Step 104: Report the type attribute information and the service type of the received data stream to the PCRF, where the type attribute information includes an instance identifier and/or instance specific information.

In this way, the PCRF does not blindly send the control policy to the service control device. When the PCRF receives the type attribute information and the service type of the data flow reported by the service control device, the data flow corresponding to the type attribute information of the service type is determined. Control rules are returned to the business control device. The PCRF can be configured according to the policy preset in the PCRF when the control rule is formulated. For example, the bandwidth of the first FTP service of the user equipment corresponding to a user identifier is higher in the PCRF, and the bandwidth of the user equipment is higher. The bandwidth of the second and third FTP services is reduced in sequence, so that the user equipment does not use too much FTP service and wastes resources. The PCRF can also obtain the user subscription information of the user equipment from the SPR, and sign the information from the user. Extract the corresponding control rules.

The service control device receives the control rule corresponding to the type attribute information of the reported data flow for the service type reported in the above-mentioned step 101.

Embodiment 2 of the present invention

The method for controlling the data flow transmitted by the user equipment by using the PCRF in the PCC architecture shown in FIG. 2, which is deployed in the communication network system shown in FIG. It is a method performed by the PCRF. The flow chart is shown in Figure 5. It includes:

Step 201: Formulate a control strategy for the data flow, where the control policy includes the type attribute information of the data flow and the corresponding control rule, where the type attribute information of the data flow includes an instance identifier and/or instance specific information of the data flow. And the control rules corresponding to different types of data streams under the same service type are different.

Step 202: Send a control policy of the data flow to the service control device, to instruct the service control device to perform corresponding policy control on the data flow of the user equipment according to the control policy.

The PCRF can actively trigger the process of the embodiment, and first obtain information required for formulating a control policy corresponding to a user equipment, for example, acquiring user subscription information from the SPR, and obtaining a service letter from the AF entity. Interest rate, and according to the information to develop a control strategy and then sent to the service control device such as TDF or PCEF or gateway device; PCRF can also passively accept information from other devices such as AF entities or gateway devices, passively request the PCRF to develop appropriate control The policy is then sent to a service control device such as a TDF or PCEF or gateway device to policy control the data flow. The method for controlling the data flow of the service control device is as described in the foregoing first embodiment, and details are not described herein.

It can be seen that, when performing service control in the embodiment of the present invention, the PCRF determines a control strategy for the data flow, and sends the control policy to a service control device, such as a TDF or a PCEF or a gateway device, and the service control device pairs the user according to the control policy. The data flow of the device is controlled by the corresponding policy. In this embodiment, the type attribute information of the data stream and its corresponding control rule are included in the control policy, so that different types of data streams under the same service type can be controlled differently, and the control precision of the data stream is improved.

It should be noted that the service control process shown in FIG. 5 is a method in which the PCRF actively sends a control policy to control the data flow. In other specific embodiments, the service control process may also be triggered by the service control device. Specifically, after receiving the data stream transmitted by the user equipment, the service control device may determine a service type of the data stream, allocate an instance identifier to the data stream, and/or obtain instance-specific information of the data stream, and The type attribute information (including instance identification and/or instance-specific information, etc.) and the service type of the data stream are reported to the PCRF.

In this way, the PCRF does not blindly send the control policy to the service control device according to the above steps 201 and 202, but performs the above steps 201 and 202 after the PCRF receives the type attribute information and the service type of the data flow reported by the service control device. . In this case, when performing the above step 201, the PCRF obtains a control rule corresponding to the type attribute information of the reported data stream under the reported service type.

Embodiment 3 of the present invention

The service control method of the embodiment of the present invention is specifically described. The flowchart is as shown in FIG. 6, and includes:

Step 301: The user equipment accesses the AF entity of the video to watch the free video.

Step 302: The AF entity notifies the PCRF that, under the video service, the user equipment accesses the instance-specific information of the video stream (such as the address information of the AF entity) transmitted during the process of the AF entity, and transmits the QoS requirement corresponding to the video stream. . Step 303, in the process of the user equipment accessing the AF entity of the video, when the service control device detects the video stream of the user equipment, and detects instance-specific information of the video stream (such as the address information of the AF entity that provides the video stream), An instance identifier is assigned to the video stream, and the service type and the instance identifier and the instance specific information of the video stream are reported to the PCRF.

Step 304: The PCRF receives the information reported by the service control device, and compares the instance-specific information of the video stream in the reported information with the instance-specific information obtained in step 302. If they are consistent, the PCRF obtains the information obtained in step 302. The QoS requirement is to set a control rule that is consistent with the QoS requirement for the video stream represented by the instance-specific information, and may specifically include parameters such as a QoS class identifier, or an ARP, or an MBR, or a GBR.

Step 305: The PCRF sends the formulated control policy to the service control device, where the type attribute information of the video stream and its corresponding control rule are included.

Step 306: The service control device performs policy control on the corresponding video stream according to the control policy received in step 305, for example, limiting the bandwidth.

It should be noted that, in this embodiment, the PCRF formulates a control policy according to the information reported by the service control device and the information sent by the AF entity. In other specific embodiments, the PCRF receives the foregoing step 302 and receives the control policy. After the instance-specific information and the QoS requirement are sent by the AF entity, the information of the control policy is not required to be executed, and the foregoing step 304 is performed to determine the control policy. Specifically, the instance-specific information directly sent by the AF entity is represented. The video stream formulates control rules that are consistent with this QoS requirement.
