Abstract: Disclosed is a method for controlling a base station which provides a service for a terminal having a low priority and a terminal having a high priority. When the terminal having a low priority and the terminal having a high priority perform initial ranging, a base station determines whether call congestion occurs. If the base station determines that call congestion occurs, the base station appoints the size of an initial ranging backoff window which is included in an information element of Secondary- Superframe Header SubPacket3 (S-SFH SP3) as a first size, and the size of an initial ranging backoff window for the second terminal as a second size in a system configuration message. The method allows to improve the possibility of success of the terminal having a high priority in initial ranging.

Abstract: A mobile relay station (RS) and a handover method for the same are disclosed. If the mobile RS determines handover from an upper base station (BS) to a target BS, the mobile RS receives information representing acceptance of the handover from the upper BS. Then, the mobile RS transmits a service unavailable section to a lower terminal and prevents the handover of the lower terminal which receives the service unavailable section through the mobile RS to the other BS or the other RS.
