[0023] In the prior art, the PCRF determines the PCC rules based on the user's subscription information, service information, and bearer information, and cannot implement policy and charging control based on the user's service traffic. The traffic is B1. When the user's business traffic exceeds B1, the corresponding policies and charging rules cannot be regenerated

Embodiment 1

[0056] image 3 Shown is the method for implementing policy and charging control in Embodiment 1 of the present invention. In this embodiment, when a user goes online, the PCRF obtains the user's service flow and accumulated usage flow from the OCS, including the following steps:

[0057] 301: User X sends a bearer request message to the PCEF to request establishment of a service bearer, where bearer information is carried in the bearer request message;

[0058] 302: After receiving the bearer request message, the PCEF sends a policy rule request message to the PCRF to request delivery of the PCC rule, wherein the policy rule request message carries the bearer information in the bearer request message;

[0059] 303: After receiving the policy rule request message, the PCRF learns that the user is online, sends a subscription information request message to the SPR, and requests the SPR to issue the subscription information of user X;

[0060] 304: After receiving the subscript...

Embodiment 2

[0079] Figure 4 Shown is the method for implementing policy and charging control in Embodiment 2 of the present invention. In this embodiment, when a user goes online, the PCEF obtains the user's service flow and accumulated usage flow from the OCS, and reports it to the PCRF through a policy rule request message, including the following steps :

[0080] 401: User X sends a bearer request message to the PCEF, requesting to establish a service bearer, where the bearer information is carried in the bearer request message;

[0081] 402: After receiving the bearer request message, the PCEF sends a traffic request message to the OCS, requesting the OCS to deliver the user's service traffic and accumulated usage traffic;

[0082] 403: After receiving the traffic request message, the OCS sends the user's service traffic and accumulated usage traffic to the PCEF;

[0083] The service traffic of user X for service B is C1, and the accumulated usage traffic is C2.

[0084] 404: Afte...

Embodiment 3

[0100] Figure 5 Shown is the method for implementing policy and charging control in Embodiment 3 of the present invention. In this embodiment, when a user subscribes to a service flow, the PCRF is notified of the user's service flow, which includes the following steps:

[0101] 501: When signing up service traffic for user X on the contracting device, the OCS or the operator's operation and maintenance support system notifies the PCRF of the service traffic of user X, and the PCRF stores or updates the service traffic signed by user X;

[0102] Whether to use the OCS or the operation and maintenance support system to notify the PCRF of the service flow can be actively selected by the operator.

[0103] 502: User X sends a bearer request message to the PCEF to request to establish a service bearer, where the bearer information is carried in the bearer request message;

[0104] 503: After receiving the bearer request message, the PCEF sends a policy rule request message to the...

Abstract

A method for realizing Policy and Charging Control (PCC), includes that: the Policy and Charging Rules Function (PCRF) receives a policy and charging rules request message sent by the Policy and Charging Enforcement Function (PCEF), then compares acquired service flow of user with accumulative used flow, and according to the comparing result, constitutes PCC rule in term of local configured or acquired flow control policy. PCRF of the present invention makes PCC rule decision according to acquired service flow of user, accumulative used flow and flow control policy, and transmits PCC rule to the PCEF to execute. And, PCEF reports to PCRF when the service flow of user arrives at a threshold, PCRF makes PCC rule decision again and transmits to PCEF to execute, consequently the purpose of policy and charging control according to the service flow of user is achieved.

Description

technical field [0001] The invention relates to a mobile communication system, in particular to a method for realizing policy and charging control. Background technique [0002] The whole network IP is the future development direction of the telecommunication network. With the widespread development of multimedia services in the IP network, how to charge different multimedia services correctly has become a topic that operators generally pay attention to. For this reason, many standardization organizations have proposed the concept of FBC (flow-based charging). At present, the 3GPP (3rd Generation Partnership Project) standard organization organically combines Qos (Quality of service) policy management and flow charging, and proposes a PCC (Policy and Charging Control, policy and charging control) system architecture. The PCC system architecture can be applied to both offline charging and online charging application environments. figure 1 Shown is the PCC system architectu...
