FIELD: radio engineering, communication.
SUBSTANCE: method involves receiving secondary superframe header (S-SFH) information from a base station; determining whether the mobile communication system supports WirelessMAN OFDMA technology; obtaining ranging channel information for performing an initial ranging, a handover ranging and a periodic ranging from the S-SFH, when the mobile communication system supports WirelessMAN OFDMA technology; and performing at least one of the initial ranging, the handover ranging and the periodic ranging with the base station using the ranging channel information.
EFFECT: efficient control of mobile station ranging and reducing undesirable overheads.
