Abstract:
1. A wireless communication apparatus comprising: a wireless communication unit for executing wireless communication by connecting to a first wireless communication network and a second wireless communication network different from the first wireless communication network; an execution unit for executing an application for real-time communication via the wireless communication unit; a jitter buffer for absorbing jitter by temporarily accumulating packets of the application being executed by the execution unit received via the wireless communication unit; a communication quality obtain unit for obtaining communication quality of a wireless link in the first wireless communication network; a handover control unit for starting handover from the first wireless communication network to the second wireless communication network based on the communication quality obtained by the communication quality obtain unit; and a control unit for determining when a predetermined time has elapsed and thereafter controlling a reproduction speed of the application based on an accumulated packet amount in the jitter buffer when an average of a reception interval of packets of the application received via the wireless communication unit is less than a predetermined value, wherein the predetermined time is equal to a sum of a difference between delay times of the first and second wireless communication networks and a time to receive a few packets.
