GROUP DETECTION AND INTER-GROUP MERGE METHOD AND ITS APPARATUS

摘要

PURPOSE: A group detecting and inter-group merging method and an apparatus thereof are provided to guarantee mobility support of a node, continuous service support and QoS(Quality of Service) of a real time traffic. CONSTITUTION: The BPST(Beacon Period Start Time) of a super frame is discriminated(S801). When the BPST belongs to a different group and BPST detection of a counterpart group is possible, a beacon interval of the counterpart group is detected in a signaling slot(S803,S805,S807). If the BPST detection of the counterpart group is impossible, the counterpart group is detected using CC(collision count)(S823). If the beacon interval is detected, a beacon slot is reset/merged(S811,S813). Resource reservation is performed using BCC(beacon collision count) and DCC(data collision count) according to a detection result of the counterpart group(S825).
