Problems solved by technology

[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

The invention discloses a method for realizing policy and charging control, which comprises the following steps: after the Policy and Charging Rules Function (PCRF) receives policy rules request message transmitted by the Policy and Charging Enforcement Function (PCEF), comparing the acquired traffic flow of a user with the cumulative flow, determining the Policy and Charging Control (PCC) rules based on the comparison result according to the locally configured or the acquired traffic control policy. The PCRF performs the PCC rules decision based on the acquired traffic flow of the user, the cumulative flow and the flow control policy, and delivers the PCC rules to the PCEF to execute. Moreover, the PCEF reports to the PCRF when the traffic flow of user reaches to a threshold, the PCRF re-performs the PCC rules decision and delivers the PCC rules to the PCEF to execute, so as to achieve the policy and charging control based on the traffic flow of the user.

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...
