Problems solved by technology

However, the AF in the existing PCC architecture is mainly for IMS applications, and the application service information sent by the AF to the PCRF through the Rx interface is mainly designed for the needs of IMS applications. Sending data application service information to PCRF makes PCRF unable to make policy decisions, thus failing to meet the network's requirements for policy control such as QoS and charging of data application services in non-IMS
[0062] Moreover, in the prior art, when the PCRF makes policy decisions, it does not consider that different service providers may adopt different strategies when providing the same service

Embodiment 1

[0169] Embodiment 1: Song-on-Demand

[0170] Song-on-demand usually uses RTSP as the flow control protocol, and data application service data flow is transmitted in RTP mode. Through RTSP signaling, the user terminal can implement operations such as start, pause, and termination of on-demand broadcasting. The following table shows an example of RTSP signaling for the on-demand process:

[0171]

[0172]

[0173] Among them, process 1 shows that the user terminal requests the media server to extract the service flow description, and the media server returns information according to the request; process 2 shows that the user terminal and the media server respectively set the port numbers used for transmitting the service stream; process 3 shows that the user terminal starts The process of ordering songs; process 4 indicates that the user terminal requests to suspend the on-demand service; process 5 indicates that the user terminal requests to terminate the on-...

Embodiment 2

[0220] Embodiment 2: FTP download.

[0221] FTP download is the most commonly used data application service. When users perform FTP services, they only need to negotiate the transmission port number, and there is no SDP negotiation process. In addition, because the service provider or network operator for the FTP download service adopts a web-based protocol, it is considered that when the data application service information is delivered in this embodiment, XML description is used to deliver the information, and the HTTP protocol is used to transfer the information.

[0222] The FTP download service carried out on the telecommunications network can be provided by Sohu (ASP1) and NetEase (ASP2), but there are differences in the charging methods adopted by ASP1 and ASP2 for providing FTP downloads. The billing method is based on the downloaded content. Therefore, when implementing policy control on the FTP download service, the issued application service information should...

Embodiment 3

[0247] Embodiment three: FTP download. see Figure 10 shown, including the following steps:

[0248] 1) The FTP application negotiation is completed between the client and ASP1;

[0249] 2) ASP1 sends the application service information corresponding to the download service to PCRF, and the sent information includes the ASP-Identifier, indicating that the FTP download service is provided by ASP1;

[0250] 3) PCRF receives the application service information issued by ASP1, and ASP1 provides FTP download service according to ASP-Identifier perception, and combines application service information and other information (operator policy, user subscription information, access network type) to formulate the service Corresponding policies, such as allocating QoS for the FTP download service provided by ASP1, formulating billing policies, gate control policies, etc.;

[0251] 4) PCRF sends the policy to PCEF for execution;

[0252] 5) According to the policy, the PCEF ...

Abstract

The invention discloses a strategic control method and a device of an application, which aims at performing different strategic decisions according to different services provided by different application service providers while the strategic control of the application can be realized. The strategic control method of the application comprises the following steps that: a policy charging rules function (PCRF) obtains a mark of an application service provider; and the PCRF performs the decision making according to the mark of the application service provider. A strategic control and charging rules function entity comprises an obtaining unit for obtaining the mark of the application service provider, and a decision-making unit for decision making according to the mark of the application service provider obtained by the obtaining unit.

Description

technical field [0001] The present invention relates to the communication field, in particular to an application policy control method and device. Background technique [0002] 1. During the evolution of the communication network to all-IP, in order to provide services that satisfy customers, it is necessary to solve the end-to-end QoS (Quality of Service) problem. IP network can provide a variety of services (such as VoIP, video on demand, file download, web browsing, etc.), different services have different requirements for QoS, and the requirements for charging are also different (for example, online accounting can be used) billing or offline billing, billing based on traffic or billing based on time, etc.). In order to solve the above-mentioned QoS and charging-related problems, 3GPP defines a PCC (Policy Control and Charging) architecture to meet different QoS control and charging requirements for different services. The PCC architecture is defined in TS 23.203, see ...
