Abstract
A mobile radio communication system includes a plurality of base stations connected to a network through wire lines, and a plurality of mobile stations connected to the base stations through radio channels. The base and mobile stations share a plurality of radio frequencies and transmit at least one transmission signal at one of the shared radio frequencies. The transmission signal is arranged into time frames each having a plurality of time-division multiplexed slots. The base and mobile stations both include a control circuit having means for detecting unused time slots within the transmission signal and means for selecting one of the unused time slots. A radio channel establishing circuit establishes a channel between the mobile radio communication apparatus and the base station in accordance with the selected time slot.
