LOCAL INTERNET PROTOCOL (IP) ACCESS OR SELECTED INTERNET PROTOCOL TRAFFIC OFFLOAD ESTABLISHMENT METHOD AND SYSTEM

摘要

The present invention provides a Local Internet Protocol Access (LIPA) or Selected Internet Protocol Traffic Offload (SIPTO) establishment method and system. The method includes the following steps: a user terminal is handed over from a source base station to a target base station; an LIPA or SIPTO from the user terminal to a first local gateway via the target base station is released, and an LIPA or SIPTO from the user terminal to a second local gateway via the target base station is established. With the present invention, the network resource consumption and the user data transmission delay are reduced, and the user experience is improved.
