<p>There is provided a radio mobile terminal device which makes a connection via an interface automatically connectable to a transmission side or a reception side even when one of the interfaces of the reception side is disabled for connection. The radio mobile terminal device includes a telephone number management unit (112) for managing a telephone number and a terminal type of a partner registered in advance and a dual terminal judgment unit (113) for judging whether the terminal device of the partner is a dual terminal. When a user performs a transmission operation, the telephone number management unit (112) and the dual terminal judgment unit (113) judge whether the partner is a dual terminal and, if a dual terminal, they perform transmission to a telephone number corresponding to the two radio interfaces of the partner. On the other hand, upon detection of a reception request by a radio interface corresponding to a cellular mobile telephone system, it is judged whether the partner transmission is a dual terminal. If the partner is a dual terminal and if the radio interface corresponding to the radio LAN system can be connected, reception is performed by the radio interface.</p> |
