ABSTRACT:
A dual mode mobile terminal has a dual mode in which said mobile terminal can be connected to any of two different wireless communications systems (hereinafter referred to as systems1and2). The mobile terminal can be connected to optimum wireless communications system by considering conditions at which the mobile terminal is (moving speed, communication data rate) even if it is in the state of communicating using any of systems1and2. The mobile terminal (3) which can be connected to any of the system1having a wide service area and medium and low communication data rate and the system2having a local service area and high communication data rate determines whether or not it is in the service area of the systems1and2. Based upon the moving speed and/or the communication data rate of the current mobile terminal (3), the mobile terminal (3) is connected to the system1or2if the moving speed is higher or lower than a predetermined threshold, respectively, and is connected to the system2or1if the communication data rate is higher or lower than a predetermined threshold, respectively, irrespective of whether the mobile terminal is in the communicating state or not. Prior to connection, selection of the wireless system is informed to the user and the connection may be made in accordance with an instruction from the user.
