  • Dual-mode system and dual-mode wireless terminal
    Patent number: 8682386
    Abstract: A base station of a first mobile communication mode communicates with a terminal in the first mobile communication mode and transmits a radio signal in a second mobile communication mode, and a base station of the second mobile communication mode communicates with the terminal in the second mobile communication mode and transmits a radio signal in the first mobile communication mode. A first unit of a dual-mode portable terminal communicates with the base station of the first mobile communication mode in the first mobile communication mode, receives the radio signal of the first mobile communication mode transmitted from the base station of the second mobile communication mode and determines based upon this radio signal whether the base station of the second mobile communication mode exists. Similarly, a second unit of the dual-mode portable terminal determines whether the base station of the first mobile communication mode exists.
