Problems solved by technology

[0023] However, in the current local IP access (LIPA, LocalIPAccess) technology, how to perform dynamic QoS control on the flow of the data stream accessed by the mobile user's local IP is not yet clear. When the mobile network and the fixed network belong to different operators, there will be In the event that this part of traffic cannot be precisely controlled, the transmission quality of these data streams cannot be guaranteed, affecting the normal development and operation and maintenance of network services

Embodiment Construction

[0084] The technical solutions of the present invention will be further elaborated below in conjunction with the accompanying drawings and specific embodiments.

[0085] In order to realize the dynamic QoS control of the traffic flow of the data flow accessed by the local IP of the mobile user, the present invention provides a policy control method for the local access of the mobile user. The policy decision-making entity of the local access network (IP-CAN, IP-ConnectivityAccessNetwork) session formulates policies for local access, and sends the formulated policies to the policy enforcement entity of the mobile network and the policy decision-making entity of the fixed network; The policy decision-making entity of the mobile network forwards the received policy to the policy enforcement entity of the fixed network; the policy enforcement entity of the mobile network and the policy enforcement entity of the fixed network install and execute the received policy.

Abstract

A policy control method for local access of a mobile user is disclosed in the present invention, and includes: a policy decision entity in a mobile network makes a policy for IP Connection Access Network (IP-CAN) session, and respectively transmits the made policy to a policy execution entity in the mobile network and a policy decision entity in a fixed network; the policy decision entity in the fixed network transmits the received policy to a policy execution entity in the fixed network; the policy execution entity in the mobile network and the policy execution entity in the fixed network install and perform the received policy. A policy control system for local access of a mobile user is also disclosed in the present invention. The method and system of the present invention realize the dynamic Quality of Service (QoS) control for the data stream flow of the mobile user local IP access.

Description

technical field [0001] The invention relates to the access technology in the field of mobile communication, in particular to a policy control method and system for local access of mobile users. Background technique [0002] The 3rd Generation Partnership Project (3GPP, 3rdGeneration Partnership Project) Evolved Packet System (EPS, EvolvedPacketSystem) consists of Evolved Universal Mobile Telecommunications System Terrestrial Radio Access Network (E-UTRAN, EvolvedUniversalTerrestrialRadioAccessNetwork), Mobility Management Unit (MME, MobilityManagementEntity), service Gateway (S-GW, ServingGateway), Packet Data Network Gateway (P-GW, PacketDataNetworkGateway), Home Subscriber Server (HSS, HomeSubscriberServer), 3GPP authentication, authorization and accounting (AAA, Authentication, Authorization and Accounting) server, policy and accounting rules It consists of functional entities (PCRF, Policy and ChargingRulesFunction) and other supporting nodes. [0003] Existing EPS syst...
