METHOD, APPARATUS AND SYSTEM FOR IMPLEMENTING POLICY CONTROL
First Claim
1. A method for implementing policy control, comprising:
- by a Service-based Policy Decision Function (SPDF), receiving a service request that carries a service property of a session from an Application Function (AF), making a service policy decision according to the service property of the session and policy pre-configuration parameters to obtain authorized service parameters; and
determining a corresponding local network transmission Policy Decision Function (PDF) according to a type of an access network; and
sending, by the SPDF, an access network resource authorization request that carries the authorized service parameters to the determined local network transmission PDF, to enable the local network transmission PDF to generate a local network transmission policy according to the authorized service parameters and deliver the policy to a corresponding policy enforcement point for enforcing.

Abstract
A method, an apparatus and a system for implementing policy control are disclosed. The method includes: an SPDF receives a service request that carries service property of a session from an AF, makes a service policy decision according to the service property of the session and policy pre-configuration parameters to obtain authorized service parameters; and determines a corresponding local network transmission PDF according to a type of an access network; the SPDF sends an access network resource authorization request that carries the authorized service parameters to the determined local network transmission PDF, to enable the local network transmission PDF to generate a local network transmission policy according to the authorized service parameters and deliver the policy to a corresponding policy enforcement point for enforcing. Through the embodiments of the present invention, the converged policy control can be implemented for different types of networks.
