Abstract
A wireless communication terminal () which performs handover control of wireless base stations acquires a layer 2 address concerning a new wireless base station () from a wireless communication interface unit (A) before handover. A presence confirmation request transmitting unit (D) transmits a presence confirmation request message to the layer 2 address acquired by an address acquisition unit (B) via a currently connected wireless base station (). Based on the presence confirmation response message reception result of a presence confirmation response receiving unit (E), a subnet determination unit (F) determines whether the new wireless base station () belongs to the same subnet as that of the wireless communication terminal ().
