Document Type and Number:
WIPO Patent Application WO/2019/041142
Kind Code:
A1
Abstract:
Disclosed are a path switching method and a base station. The method comprises: after a terminal device completes switching from a source base station to a target base station, the target base station carrying out path extension based on a logic direct connection interface between the target base station and a first base station, so as to form a target path for transmitting service data between the terminal device and a core network, wherein anchor points of the target path are an anchor base station, directly communicating with the core network, in the target path; and by means of the target path, the target base station transmitting the service data received from the terminal device to the core network or sending, by means of the target path, the service data received from the core network to the terminal device. Therefore, no matter how a terminal device switches between base stations, anchor points of a target path for transmitting service data between the terminal device and a core network are all an anchor base station, thus preventing greater signaling overheads generated between the base station and the core network during path switching.
