In order to perform handover from a first wireless communication network to a second wireless communication network, a handover control unit obtains a handover preparation time to handover, and by receiving data via the first wireless communication network and the second wireless communication network separately obtains a delay time difference between the networks based on reception times of the same data. Based on such information obtained and an amount of the data in a jitter buffer at a point to determine to start handover preparation, the handover control unit controls a reproduction speed of an application being executed. Thereby, it is possible to perform handover to a different wireless communication network without deteriorating reproduction quality and real-time property and causing packet loss.
