HANDOVER METHOD, AS WELL AS CONTROLLER AND TERMINAL DEVICE USING THE METHOD

摘要

A receiving unit receives a first list showing base station apparatuses picked up by a terminal apparatus. The first list is attendant to a request for position registration sent from the terminal apparatus to a first base station apparatus. A selector compares the received first list with a second list showing base station apparatuses subscribed to by the terminal apparatus, and selects an already-subscribed second base station apparatus picked up by the terminal apparatus. An instruction unit has the first base station apparatus instruct the terminal apparatus to perform a handover to the second base station apparatus selected by the selector.
