A distribution method and related equipment in a roaming scene

Abstract

The embodiment of the present application discloses a traffic distribution method and related equipment in a roaming scene, which are used to prevent the roaming user's subscription service traffic from looping back to the home location, reduce the traffic consumption between the networks, and realize the local traffic distribution capability of the terminal in the roaming location. Improved service quality. The method in the embodiment of the present application includes: the roaming core network control plane V-CP receives the first message sent by the home core network control plane H-CP, the first message includes the local offload LBO policy based on the subscription service, and the subscription The service is a service that the user needs to be distributed locally; the V-CP sends the LBO policy to the roaming core network user plane V-UP, so that the LBO policy is installed on the V-UP to implement the contracted service local offload processing.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a traffic distribution method and related equipment in a roaming scenario. Background technique [0002] At present, when a user uses a terminal, he will leave the home of the terminal. At this time, the terminal needs to access the roaming area where the user is located, so as to ensure that the terminal can access the network normally. In order to ensure the continuity of services in the case of user roaming switching, it is necessary to establish a network connection between the operator networks and reach a roaming agreement; operators follow the roaming agreements reached between them, configure roaming control policies, and control the network access of roaming users. Access control and corresponding operation management for roaming services. [0003] In the current 2 / 3 / 4 / 4.5G network architecture, when a user roams to another operator, the general use...

Problems solved by technology

[0004] When this technical solution is adopted, various application service (over the top, OTT) service providers or content providers (Content Provider) are provided to users through the Internet by deploying a content delivery network (content delivery network, CDN) server near the place of origin to realize local In the scenario where offloading is used to improve service access quality and reduce inter-network traffic consumption, all service traffic is looped back to the user plane (home user plane, H-UP) of the home core network, and then offloaded to the Gi side and looped back to roaming through the Internet Local CDN servers will consume a lot of Internet traffic and increase service access delays
