<p>A second control apparatus (1B) is configured to be able to investigate handover possibilities of a plurality of cells including cells (41B, 42A, and 42C) in response to receipt of a handover request message transmitted from a first control apparatus (1A). The second control apparatus (1B) is configured to transmit an acknowledge response message indicating handover acknowledgment to the first control apparatus (1A) when at least one of the plurality of cells can accept a handover of a mobile station (3). As a result, extra signaling related to a handover procedure can be reduced.</p> |
