WIPO Patent Application WO/2016/176952

Kind Code:

A1

Abstract:

A cellular network relocation method and base station. The method comprises: transmitting, by a source base station and to a relocation target base station, a relocation request message used to instruct the target base station to perform a main user plane function, the relocation request message carrying context information of a terminal in the source base station; receiving, by the target base station, the relocation request message, and then returning to the source base station a relocation request acknowledgement message used to acknowledge that the target base station itself is a main base station after the relocation, the relocation request acknowledgement message carrying a user plane address of the target base station for receiving a data package after the relocation; receiving, by the source base station, the relocation request acknowledgement message, then transmitting the context information of the main user plane function of said base station to the target base station, and terminating performing of the main user plane function; and receiving, by the target base station, the context information of the main user plane function transmitted from the source base station, and then performing the main user plane function.
