Abstract
A mobile telephone unit belongs to a mobile telephone system with a mobile telephone system and a paging system which cover an identical service area, are independently operated, and are connected through an exchange. The mobile telephone unit includes a telephone set connected to a radio transmitter/receiver and an automatic pager calling circuit. The automatic pager calling circuit includes a circuit for detecting and storing that an incoming call is made for a mobile subscriber who carries a pager and is away from a vehicle, and a circuit for sending a signal representing a preset pager number to the radio transmitter/receiver. The pager number signal for the radio transmitter/receiver is automatically sent by the paging system to the pager through the exchange, thereby calling the mobile subscriber.
