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. [Reference numerals] (100) Base station;(AA) Terminal having a low priority uses the size of an initial ranging backoff window included in S-SFH SP3;(BB) Terminal having a high priority uses the size of an initial ranging backoff window included in AAI -SCD;(S200) Initial ranging;(S210) Determine whether initial call congestion occurs;(S220) Increase the size of an initial ranging backoff window inside S-SFH SP3 IE;(S230) Secondary Superframe Header (S-SFH SP3);(S240) Write the size of an initial ranging backoff window inside AAI-SCD;(S250) System configuration information message (AAI-SCD)
