Path Switch Control Method for Wireless Communication System, and Controller in that System

摘要

The present invention aims at carrying out earlier path switching control and suppressing any reduction in the communication efficiency of wireless communication.
For this purpose, in a wireless communication system (40) including a wireless terminal (30), a plurality of wireless base stations (2-1 and 2-2) that wirelessly communicate with the wireless terminal (30), and a controller (1) that changes the path used for communication with the wireless terminal (30) from a first path via a first wireless base station (2-1) to a second path via a second wireless base station (2-2), the controller (1) monitors the amount of remaining data to the wireless terminal (30) at the first wireless base station (2-1), controls to the timing to change to the second path according to the monitor result.
