Problems solved by technology

[0020] In the prior art, when the network performs PCC control processing on user equipment services, if the V-PCRF does not accept the authorized QoS issued by the H-PCRF, and the AF authorization fails, the AF will repeatedly request authorization from the H-PCRF, that is, repeatedly Request PCC request control from the network, causing unnecessary Rx interface signaling interaction

Embodiment 1

[0064] A method for processing policy and charging control. In this embodiment, the user equipment moves from HPLMN to VPLMN, and the access network of the user equipment is VPLMN. The signaling flow chart is as follows Figure 4 shown, including:

[0065] Step 101, user equipment registers with AF;

[0066] Step 102, the AF sends a subscription message to the PCRF through the Rx interface, and the subscription message is used to subscribe to the PCC control capability information of the VPLMN;

[0067] It can be understood that the capability information of the VPLMN to perform PCC control on the service of the user equipment includes at least one of the following: whether the VPLMN can perform QoS authorization on the service of the user equipment, flow-based charging, dynamic resource allocation, that is, end-to-end QoS authorization, Operations such as QoS authorization based on user subscription information.

[0068] Here, the AF can subscribe through the authentication...

Embodiment 2

[0088] A method for processing policy and charging control. In this embodiment, the user equipment moves from HPLMN to VPLMN, and the access network of the user equipment is VPLMN. The flow chart is as follows Figure 5 shown, including:

[0089] Step 201, the user equipment registers with the AF and initiates a service request;

[0090] Step 202, the AF sends the media message of the service to the PCRF, requesting the VPLMN to perform PCC control;

[0091] Step 203, after the PCRF receives the media message of the service, determine the PCC control capability of the VPLMN, the PCC control capability indicates whether the VPLMN can perform PCC control on the service requested by the user equipment, if it is found that the PCC control capability of the VPLMN to the user equipment is limited , then return a rejection message and carry the restricted PCC control capability information to the AF; it can be understood that when the VPLMN has no restrictions on the PCC control of ...

Embodiment 3

[0100] This embodiment provides a policy and charging control processing method. When the user equipment roams, it returns to local access. VPLMN does not deploy PCC, and HPLMN deploys PCC. Refer to Figure 6 Shown is the architecture diagram of returning home access when the user equipment roams (the network equipment related to the embodiment of the present invention is taken as an example in the figure), wherein:

[0101] The PCRF (h-PCRF) in the home network of the user equipment is connected to the PCRF (v-PCRF) in the network visited by the user equipment through the S9 interface; the packet data network gateway (PDN Gateway, P-GW) is the gateway that provides services for the connection , which also embodies the function of the PCEF; the serving gateway (Serving Gateway, S-GW) is responsible for relaying the user service flow between the user equipment and the P-GW, and also embodies the function of the PCEF. Among them, PDN Gateway obtains QoS and charging policy from ...

Abstract

A method, system and device for processing policy and charging control apply to communications technology. In the embodiment of the invention, a Policy and Charging Rules Function (PCRF) sends to an Application Function (AF) an information which indicates whether a network is capable of processing Policy and Charging Control (PCC) on the service of a user equipment, the AF sends a media message according to the reported PCC control capability, and instructs the network to process the PCC control on said user equipment service; alternatively, the AF instructs the user equipment to initiate a resource request. In embodiments of the invention, the network triggers the policy and charging control on the service of the user equipment according to the PCC capability of the actual access network; it does not occur that the AF repeatedly requests the PCC control because of a difference between the PCC capability requested by the AF and the PCC capability of the actual network, thus the interaction of the Rx interface is reduced, and the influence of the network on the session of the user equipment in the application layer is reduced.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a processing method, system and equipment for policy and billing control. Background technique [0002] In the current field of communication technology, when a user equipment is running on a network, the network needs to perform policy and charging control (PCC) on the user equipment. The 3rd Generation Partnership Project (3rd Generation Partnership Project) , 3GPP) defines a PCC architecture, such as figure 1 shown, where: [0003] The Policy Control and Charging Rules Function (Policy Control and Charging RulesFunction, PCRF) is connected to the Application Function (Application Function, AF) through the Rx interface, and obtains the current service information of the user equipment from the AF; through the Sp interface, it communicates with the user A subscription database (Subscription Profile Repository, SPR) is connected, and user subscription data is obtained fro...
