Abstract
A compound information terminal, a mobile communications system and a control method thereof, which prevent the reception on a GPS terminal unit in operation from being affected by interference without turning off a 3GPP-compliant mobile telephone unit or disabling it for transmission. The compound information terminal comprises a user interface unit, a terminal control unit, a 3GPP-compliant mobile telephone unit and a GPS terminal unit. When the GPS terminal unit is activated, the terminal control unit switches the operation of the 3GPP-compliant mobile telephone unit to the compressed mode, in which the transmission is suspended at intervals of arbitrary period of time. Accordingly, the GPS terminal unit can be brought into action while the 3GPP-compliant mobile telephone unit suspends its transmission operation. With this exclusive operation control performed between the 3GPP-compliant mobile telephone unit and GPS terminal unit, it is possible to prevent the reception on a GPS terminal from being affected by interference.
