Method and system for redirection of trigger media of packet switching mobile access network

Abstract

The invention discloses a method for redirection of trigger media of the packet switching mobile access network. The method includes that a network control system NCS requests a target media switching system MSS to build first load bearing connection for a user terminal system (UTS). The target MSS transmits Internet protocol (IP) information to a business adaptation function SA. A source MSS transmits media data received from the first load bearing connection to the UTS, or the source MSS or a radio node system (RNS) transmits received media data transmitted to the UTS to a target MSS through the first load bearing connection. A system for redirection of trigger media of the packet switching mobile access network and achieved by the method is further disclosed. By means of the method, the UTS can be relocated timely, so that UTS access routing in an optimization PS mobile access network can be triggered timely, and circuity of multimedia business flow cannot be caused.

Description

technical field [0001] The invention relates to redirection technology, in particular to a method and system for triggering media redirection by a packet switching mobile access network. Background technique [0002] Packet (PS, Packet Switching) mobile access network includes Long Term Evolution (LTE, Long Term Evolution) network, Universal Mobile Telecommunications System (UMTS, Universal Mobile Telecommunications System) network, GSM EDGE Radio Access Network (GERAN, GSM EDGE radio access network), Code Division Multiple Access (CDMA, Code Division Multiple Access) network, etc., provide users with Internet Protocol (IP, Internet Protocol) access capabilities, so that users can access the Internet network. [0003] PS mobile access network mainly includes User Terminal System (UTS, User Terminal System), Radio Node System (RNS, Radio Node System), Network Control System (NCS, Network Control System) and Media Switching System (MSS, Media Switch System) and other network ...

AI Technical Summary

Problems solved by technology

[0005] In the existing PS mobile access network, when the UTS accesses the PS mobile access network, the PS mobile access network will select an IGW of the MSS to assign an IP address to it. When the UTS performs media exchange services, the IGW Provide media exchange service for this user all the time, even if the UTS moves to a far place, the PS mobile access network will not re-select a nearby IGW in the UTS, which will cause the media path in the PS mobile access network to be interrupted Serious detours, which affect the performance of the PS mobile access network to provide services, such as longer delays, etc.
