Embodiment Construction

[0069] image 3 A flow chart of the policy control method for implementing BBF access in the present invention, such as image 3 shown, including:

[0070] Step 300: Set an FMC policy function (PF, Policy Function) in the mobile network that the user currently requests to access.

[0071] The FMC PF can be used as an independent functional entity; the FMC PF can also be integrated in the PCRF.

[0072] When the user is not roaming, the mobile network that the user requests to access is the public land mobile network (PLMN) to which the user belongs; when the user is roaming, the mobile network that the user requests to access is the PLMN that the user visits.

[0073] Step 301: After receiving the trigger message from the ePDG, the FMC PF requests the BPCF to establish a policy control session.

[0074] After the UE accesses the BBF access system, the BBF access system will assign a local IP address to the UE; then, the UE initiates the Internet Key Exchange Version 2 (IKEv...

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...
