Policy information obtaining method, policy information providing method and communication system

Abstract

An embodiment of the invention provides a policy information obtaining method, a policy information providing method and a communication system. The policy information obtaining method comprises the steps of: receiving a first policy information request message sent by a broadband network gateway, wherein the first policy information request message carries identification information of a home base station policy module as well as a terminal identification and/or identification information of a broadband network where the terminal accesses; sending a second policy information request message to the home base station policy module according to the identification information of the home base station policy module, wherein the second policy information request message carries the terminal identification and/or the identification information of the broadband network where the terminal accesses; receiving a first policy information request response message returned by the home base station policy module, wherein the first policy information request response message carries the policy information; sending a second policy information request response message which carries the policy information to a broadband network gateway. The invention also provides a corresponding policy information providing method and a communication system.

Description

Technical field [0001] The embodiments of the present invention relate to communication technology, and in particular to a method for acquiring policy information, a method for providing policy information, and a communication system. Background technique [0002] In the 3rd Generation Partnership Project (3rd Generation Partnership Project, hereinafter referred to as: 3GPP) system, the policy and charging functions are implemented by the Policy and Charging Control (PCC) framework, and the PCC framework It is a system architecture that controls Quality of Service (QoS) and billing. The system architecture can be applied to different wireless and access network types. It can implement service flow-based QoS guarantee for user applications and in business User applications are billed at the stream level. [0003] The 3GPP terminal can access the 3GPP core network through WiFi AP devices connected to the non-3GPP access network, or access the 3GPP core network through the Femto cell...
