Mobile station registration with timing re-allocation and de-allocation

摘要

A wireless communication system includes a plurality of mobile stations and a base station which periodically receives a predetermined kind of information from one or more registered mobile stations registered in the base station among the plurality of mobile stations via a radio channel shared among the registered mobile stations. The base station determines a transmission interval of the information for the registered mobile stations in accordance with the number of the registered mobile stations, allocates transmission timings of the information for the registered mobile stations to be different among the registered mobile stations in the transmission interval, and notifies the registered mobile station of the transmission interval and the transmission timing. Each one of the registered mobile stations periodically sends out the information to the radio channel in accordance with the transmission interval and the transmission timing.
