ABSTRACT:
According to the temporary address system in the radio communications system of the present invention, as a temporary address data, an identification number determined based on the number of repeated zones in which the pattern of the same frequency is repeated, is assigned to a radio base station, and a temporary identification number, which is valid temporarily in the area of the base station is assigned to a terminal device. Real address data, which corresponds to said temporary address data, and is used to specify a terminal device, is stored in a not-yet-used transmission data field during traffic of control data, which is conducted for setting up a radio link between a base station and a terminal device, and is transmitted. Thus, in the radio communication system, using an address field having a limited number of bits, more number of terminal devices than that is possible with the bit length, can be used in the area of a base station.
