Abstract
A mobile communication system including a plurality of radiotelephone base stations respectively covering a plurality of cells to define in combination a service area, a mobile unit capable of communicating with the radiotelephone base stations, and a radiotelephone control unit for connecting together each of the base stations and an ordinary telephone network, setting up and releasing a speech path between the each radiotelephone base station and the mobile unit, and adding a speech path for communication with another radiotelephone base station which is able to communicate with the mobile unit as it moves. The mobile unit is adapted to transmit and receive a plurality of channels at the same time so that it is capable of communicating with a plurality of radiotelephone base stations and registering its position to these base stations. The mobile unit successively registers its position to radiotelephone base stations with which it can communicate as it moves, so that the mobile unit can communicate with a telephone set in the telephone network without instantaneous disconnection via all the base stations where it has registered the position.
