WIRELESS COMMUNICATION APPARATUS AND HANDOVER METHOD

摘要

A wireless communication apparatus capable of shortening the handover time and preventing the connection from being interrupted during telephone communication. In this apparatus, an HO part (109), when detecting an access point, outputs an handover control signal for performing a handover that is a process of switching from a communication using a third generation mobile communication system to a communication using a WLAN. A positional information acquiring part (112) receives a GPS signal transmitted from a GPS satellite and generates GPS information indicative of the position of the local apparatus. When the GPS information shows that the local apparatus approaches the area of the WLAN by a predetermined distance, a period deciding part (115) decides that the period be shorter than when the local apparatus is at the predetermined distance away from the area of the WLAN. When the local apparatus approaches the area of the WLAN by the predetermined distance, an AP detection period control part (116) controls the operation of access point detection to be performed in the period shorter than when the local apparatus is at the predetermined distance away from the area of the WLAN.
