Method for implementing limited policy and charging control and system thereof

摘要

The present invention provides a method and system for implementing limited policy and charging control. The method comprises a PCRF determining whether a visited network where a UE roams supports PCC, and sending a message containing an identifier indicating the limited policy and charging control deployment to an AF. After receiving the message containing the identifier, the AF performs no subscription of the event trigger and/or cancels the subscription of the event trigger based on the identifier. Using the method and system in accordance with the present invention, the AF can be notified more conveniently and accurately of the current policy and charging control deployment situation when the limited policy and charging control is implemented (i.e., when the visited network does not support the PCC). Moreover, the AF may perform the corresponding operations according to the current policy and charging control deployment situation, thereby saving system resources.

主权项

1. A method for implementing limited policy and charging control comprising:
a policy and charging rules function (PCRF) device that determines whether a visited network where a user equipment (UE) roams supports policy and charging control (PCC), and notifying an application function (AF) of a limited policy and charging control deployment if the visited network does not support the PCC; and when the PCRF device detects that the UE moves to a network supporting the PCC, the PCRF device then sending a limited policy and charging control deployment recovery indication identifier to the AF.
