Abstract
A mobile communication terminal device which includes a plurality of different communication interfaces that are automatically switched for making a communication. The stable connection is ensured whether the terminal device remains at rest or is moving by monitoring positional information on the terminal device for a moving situation thereof to control a selection from a plurality of physical interfaces. This selection control involves selecting a connection to a narrow range communication such as wireless LAN which is inexpensive and stable when the terminal device remains at rest, and selecting a connection for a communication through a portable telephone which provides a connection over a wider range when the terminal device is moving. Also, a connection for a communication is automatically selected from the positional information, thereby permitting an automatic selection of a connection intended by the user.
