发明名称 SYSTEM AND METHOD FOR STATE SYNCHRONIATION BETWEEN BASE STATION AND MOBILE STATION IN A BROADBAND WIRELESS ACCESS COMMUNICATION SYSTEM
摘要 <p>A system and method for the state synchronization between a base station and a mobile station in a BWA(Broadband Wireless Access) communication system are provided to enable an MS(Mobile Station) to match state synchronization with a BS(Base Station) as the BS, in case that the CPU is reset, sends a changed reset count value to the MS and the MS executes network re-entry procedures after comparing the present reset count value with the previous reset count value. A base station periodically transmits a downlink frame containing DLFP(Downlink Frame Prefix) information to an MS(702,704). Whenever DLFP information is received, the MS extracts a reset count value and compares the extracted present reset value with a previously stored old reset count value(706). If a CPU of the BS is reset(708), the BS increases the reset count value by 1(710). Then, the BS transmits DLFP information containing the increased reset count value to the MS(712). At this time, the MS compares the present reset count value contained in the received DLFP information with a previously stored old reset count value(714). If it is judged that the two values are different, the MS, recognizing that the CPU of the BS has been reset, executes network re-entry procedures for state synchronization with the BS(716).</p>
