PROBLEM TO BE SOLVED: To provide a mobile portable communication terminal device which is capable of very quickly and automatically switching an interface from one to another without affecting communication applications. SOLUTION: A portable communication terminal device is equipped with two physical interfaces 108 and 109 different in kind from each other. Furthermore, it is equipped with a switch watching control means 110 which watches whether the physical interfaces 108 and 109 are kept in a workable condition or not, and indicates that the connection is switched when a position at which the above two physical interfaces can be switched from one to another is detected, and a connection management section 102 which watches the start and cutoff of the connections of the two physical interfaces 108 and 109, switches the connection when a connection dividable position at which the connection can be cut off or restarted while data are received or transmitted without affecting the applications, and shifts the current physical interface to the designated physical interface when a switching indication is issued from the switch watching control means 110 at that time. |
