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 communication quality obtain unit for obtaining communication quality of a wireless link of the first wireless communication network during execution of the application by connecting to the first wireless communication network; a determination unit for determining whether to start preparation for 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; an estimation unit, when the determination unit determines to start preparation for handover during execution of the application, for estimating a handover preparation time based on the communication quality obtained by the communication quality obtain unit, wherein the handover preparation time is the time from the determination of preparation for handover to the start of handover; a measuring unit for measuring a delay time of each of the first wireless communication network and the second wireless communication network when the determination unit determines to start preparation for handover; and a control unit for controlling a reproduction speed of the application by the execution unit based on the handover preparation time estimated by the estimation unit and the delay time of each of the first wireless communication network and the second wireless communication network measured by the measuring unit.
