METHOD AND APPARATUS FOR IMPLEMENTING OPTIMIZED CHANGEOVER

Abstract

PROBLEM TO BE SOLVED: To provide a method and system for realizing optimized network changeover.

SOLUTION: In a connection establishment process in preparation for changeover from a source network to a target network when connection between an SGW and a PDN GW is set the SGW transmits to the PDN GW a message instructing the PDN GW not to change an uplink data path and a downlink data path of a user plane from the source network to the target network. After completion of preparation for the changeover from the source network to the target network the SGW instructs the PDN GW to change the uplink data path and the downlink data path of the user plane from the source network to the target network.
