Mobile communication terminal device
DCFirst Claim
1. A mobile communication terminal device having a first physical interface for making a communication to the outside, a second physical interface different in scheme from said first physical interface, and a selection switching determination unit for selecting one from said first and second physical interfaces to switch to a selected physical interface, said mobile communication terminal device comprising:
- a communication determination unit for determining whether or not each of said first and second physical interfaces is available for a communication;
a movement determination unit for determining a moving speed of said mobile communication terminal device; and
a position detection unit for detecting a position of said mobile communication terminal device,wherein said selection switching determination unit makes a selection switching based on the communication availability determined by said communication determination unit, the moving speed determined by said movement determination unit, and the position detected by said position detection unit, andwherein said selection switching determination unit waits a longer time until switching of said physical interface when said movement determination unit determines the moving speed being faster.

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.
