Title: SWITCHING METHOD FOR TERMINAL, BASE STATION AND SYSTEM
Abstract:
A switching method for a terminal, a base station and a system. A first base station sends first switching request information to a second base station, wherein the first switching request information comprises identification information about a terminal in a first cell of the first base station; and the second base station sends second switching request information to a target base station, wherein the second switching request information comprises identification information about the terminal in the first cell. The target base station may judge whether ping-pong switching occurs for the terminal according to the second switching request information, and when the target base station is the first base station, the first base station may judge that ping-pong switching occurs for the terminal, or when the target base station is a third base station, the first base station learns that ping-pong switching occurs for the terminal through a switching report sent by the third base station. Since the first base station may recognize switching data stored in the first base station through identification information about the terminal where ping-pong switching occurs, a class of terminals where ping-pong switching occurs may be optimized, and requirements of mobility robustness self-optimization may be satisfied.
