Policy control method and system for realizing BBF (Broadband Forum) access

Abstract

The disclosure provides a policy control method and a policy control system for accessing a fixed broadband access network. The policy control method includes: a FMC PF used for sensing the access of UE to a fixed broadband access network is set in a mobile network which a user requests to be accessed to; after the FMC PF receives a trigger message from an ePDG, the FMC PF requests a BPCF to establish a policy session, and the BPCF performs, policy control according to the information of the fixed broadband access network accessed by the UE. It can be seen from the method of the disclosure that when the UE is accessed to the 3GPP through the fixed broadband access network, the FMC PF senses a gateway control session establishment request message or a DHCP request message from the ePDG, so that a PCRF of the 3GPP access network accessed by the UE is triggered to send a policy session request to the BPCF. In this way, in the case that the fixed broadband access network fails to sense the access of the UE or that the fixed broadband access network does not support 3GPP-based access authentication in the conventional art where the UE is accessed to a 3GPP core network through the fixed broadband access network, QoS control is achieved for the access of the UE, and thus QoS guarantee is provided to the entire transmission path of data.

Description

technical field [0001] The invention relates to the interconnection and intercommunication between 3GPP and Broadband Forum (BBF, Broadband Forum), in particular to a policy control method and system for realizing BBF access. Background technique [0002] figure 1 It is a schematic diagram of the structure of the evolved packet system (EPS, Evolved Packet System) of the existing 3rd Generation Partnership Project (3GPP, 3rd Generation Partnership Project), in figure 1 The EPS network architecture shown in the non-roaming scenario includes an Evolved Universal Terrestrial Radio Access Network (E-UTRAN, Evolved Universal Terrestrial Radio Access Network), a Mobility Management Entity (MME, Mobility Management Entity), and a service gateway (S-GW, Serving Gateway), Packet Data Network Gateway (P-GW, Packet Data Network Gateway, also known as PDN GW), Home Subscriber Server (HSS, Home Subscriber Server), Policy and Charging Rule Function (PCRF, Policy and Charging Rules Functi...

Problems solved by technology

In this scenario, BPCF will not be able to actively initiate the establishment of an S9* session, thus failing to implement QoS control for UE access
