COMMUNICATION TERMINAL, COMMUNICATION SYSTEM, HANDOVER PROCESS METHOD, AND PROGRAM

摘要

It is possible to provide a communication terminal, a handover process method, a communication system, and a program which can reduce a transmission delay accompanying a handover process in a mobile communication and perform a high-speed high-quality data communication. A mobile telephone (10) which can perform communication by establishing a plurality of sessions includes: an HO judgment unit (181) which judges whether to perform a handover (HO); and an HO process unit (182) which performs an HO process. The HO process unit (182) includes: a priority decision unit (1821) which decides priority of a session to be subjected to an HO when a plurality of sessions are performing communication if the HO judgment result shows that the HO process is to be executed; and an HO execution unit (1822) which executes an HO of the session according to the decided priority. The HO process unit (182) further includes an HO hold unit (1823) which holds a connection request or a disconnection request made during an HO process.
