A control unit obtains a current position of a mobile phone by using a GPS receiver during the operation of the navigation function, while detecting a style of a device body based on detection of an opening/closing sensor. The control unit determines whether to perform route guidance or to perform direction guidance based on the detected style of the mobile phone. When the mobile phone is in 'open style', the control unit displays a detailed navigation screen including route indicating map images on a main display, while displaying a simple direction guidance on a sub display when the mobile phone is in 'closed style'.

Mobile terminal device and program

A radio communication system includes a base station and a plurality of terminals including a new terminal. The system enables deletion of registration data relating to the new terminal when an end of communication between the new terminal and another terminal is detected or when one of the terminals is placed in a charger base. A new terminal is installed in the radio communication system by transmitting a system code of the base station from a terminal which has already been registered to the new terminal. In addition, communication between terminals is accomplished without sending a request signal to the base station.

Method and apparatus for expanding a radio communication system and

A radio communication system has a terminal which enables radio communication through a base station, and service condition of a radio communication terminal to register is registered together when the radio communication terminal is registered.
