A mobile communication apparatus includes a wide area receiver and a cell transceiver. The wide area receiver which is operable at relatively low power receives a selective calling signal from a wide area base station that forms a wide one-way communication area. The cell transceiver operable at higher power than the wide area receiver performs two-way communication with a nearest cell base station that forms a two-way communication area. The wide area receiver is caused to operate at all times. However, when the mobile communication apparatus exists outside the wide one-way communication area, the transceiver is caused to start operating. |
