Patent ID: 8626171

Claim:
A wireless communication apparatus connectable to plural wireless communication networks, comprising: a handover system selection unit for selecting one of a vertical synchronization system for performing simultaneous handover of vertical links, an up/down asynchronous system for performing asynchronous handover of the vertical links, a synchronization connection bandwidth complementary system for simultaneously connecting a terminal, while maintaining connection with one wireless communication network currently in use for communication, to another wireless communication network, and performing handover to the another wireless communication network so that an insufficient bandwidth is complemented, and an in-the-same-network switching system for performing handover from a base station or sector currently in use for connection to another base station or sector in the same wireless communication network; a handover control unit for controllably performing handover by using the handover system selected by the handover system selection unit; a latency storing unit for storing latency required for handover in each wireless communication network of the plural wireless communication networks, and allowable delay time prescribed for each application to be used for communication; and a time comparing unit for comparing latency stored in the latency storing unit with allowable delay time of an application in use for communication, wherein the handover system selection unit selects one of the handover systems on the basis of the comparison results by the time comparing unit with regard to whether or not the latency exceeds the allowable delay time.
