ABSTRACT:
A cordless telephone system including a independent base station and a dual purpose mobile station which enables the mobile station to respond to an incoming call from a public base station while a first phone call is being conducted by the mobile station through the independent base station. During this operation, the first phone call is either put on hold or disconnected thus enabling the mobile station to shift to the call from the public base station. The independent base station is provided with a public reception antenna, a reception radio circuit, a mobile station reception channel CODEC, a public reception control section, and a public reception interface, enabling it to receive a call signal from the public base station intended for the dual purpose mobile station. Due to this constitution, the independent base station receives the call signal from the public base station intended for the dual purpose mobile station during the first phone call.
