Mobile communications system
First Claim
1. A mobile communication system comprising:
- a one-way communication system where a wide area base station forms a wide one-way communication area;
a two-way communication system having a cellular service area which is formed by a plurality of cell base stations each forming a cellular two-way communication area;
a plurality of mobile terminals each for communicating with the one-way communication system and the two-way communication system; and
a system controller connected to the one-way communication system and the two-way communication system, for controlling mobile communications in the wide one-way communication area and/or the cellular service area, wherein the system controller transfers to the mobile telephone data addressed thereto through a selected one of the one-way communication system and the two-way communication system.

Abstract
A mobile communication system includes a one-way communication system where a wide area base station forms a wide one-way communication area and a two-way communication system having a cellular service area which is formed by a plurality of cell base stations each forming a cellular two-way communication area. A mobile terminal can communicate with the one-way communication system and the two-way communication system. Further, a system controller connected to the one-way communication system and the two-way communication system controls mobile communications in the wide one-way communication area and/or the cellular service area. The system controller transfers data addressed to a mobile terminal to the mobile terminal through a selected one of the one-way communication system and the two-way communication system.

27. A mobile terminal in a mobile communication system including a wide one-way communication system and a cellular two-way communication system, comprising:
-
a wide area receiver operating at relatively low power, for receiving a selective calling signal from a wide area base station of the wide one-way communication system; a cell transceiver operating at higher power than the wide area receiver, for two-way communication with a nearest cell base station of the cellular two-way communication system; and a communication controller for causing the wide area receiver to operate at all times and causing the cell transceiver to start operating for data reception when a start-up signal is received from the wide base station. - View Dependent Claims (28)

29. A mobile terminal in a mobile communication system including a wide one-way communication system and a cellular two-way communication system, comprising:
-
a wide area receiver operating at relatively low power, for receiving a selective calling signal from a wide area base station of the wide one-way communication system; a cell transceiver operating at higher power than the wide area receiver, for two-way communication with a nearest cell base station of the cellular two-way communication system; and a communication controller for causing the wide area receiver to intermittently operate at all times and causing the cell transceiver to start operating for data reception when a start-up signal is received from the wide base station and further to transmit a data check signal to the mobile communication system, the data check signal causing the mobile communication system to search for data addressed to the mobile terminal. - View Dependent Claims (30)
