Abstract
This invention relates to a radio base station equipment and a mobile station equipment in a mobile communication system that operate as determination stations adapted for a predetermined navigation or associate with other radio base station(s) or mobile station(s) to radio-determine the location of a desired mobile station. The mobile communication system achieves a radio determination economically and reliably while flexibly adapting itself to the substantial traffic distribution and transmission characteristics in individual wireless zones as well as the zone configuration, channel allocation, the procedure of channel control, and the structure of hardware.
