PROBLEM TO BE SOLVED: To provide a radio communication device enabling handover to a different radio communication network without causing deterioration in the quality of reproduction sound, that in the quality of a call, or the like. SOLUTION: The radio communication device includes: radio communication sections 31, 32, 34 connected to first and second radio communication networks 15, 16 to execute radio communication; an execution section 33 of an application of a real-time communication system; a jitter buffer 47 for absorbing jitter of the packet of the application; a communication quality acquisition section 35 for acquiring the communication quality of a radio link in a first radio communication network 15; a handover control section 36 for starting handover to the second radio communication network 16 from the first radio communication network 15, based on the obtained communication quality; and a control section 33 for controlling reproduction speed of the application, based on the number of stored packets in the jitter buffer 47. Based on acquisition information, the reproduction speed of the application under execution is controlled. COPYRIGHT: (C)2009,JPO&INPIT
