Abstract: PURPOSE: A communication method of a terminal is provided to execute an optimal base station role by avoiding mutual interference on a radio wave. CONSTITUTION: When a base station(100) is collapsed(S510) and a random back-off timer is terminated, a terminal(310) converts a mode(S540). After the mode is converted, the terminal is operated as a base station. A random back-off delay time calculated by the random back-off timer is determined according to the state information of the terminal. The state information includes the battery residual information of the terminal. The random back-off delay time is related to the mode conversion attempt.

Abstract: PURPOSE: A state management device of a mobile terminal considering a multicast service is provided to offer the multicast service of a single cell mode with high transmission efficiency. CONSTITUTION: Multicast data transmitted from a multicast service center is received(S100,S110). An error of the received multicast data is checked(S130). If the error is generated, an error count is increased(S150). If the increased error count arrives in a threshold(S160), a state of a mobile terminal is converted to an active state so that the mobile terminal transmits CQI(Channel Quality Information) to a base station(S170).

Abstract: PURPOSE: A scheduling method for an MBMS(Multimedial Broadcast/Multicast Service) is provided to receive a unicast service, a broadcast service and a multicast service at the same time. CONSTITUTION: If a scheduling request message is received(S100), an assignment priority of a plurality of RNTIs(Radio Network Temporary Identifiers) is decided according to a predetermined scheduling assignment priority(S110). If the assignment priority of at least one RNTI among a plurality of RNTIs is decided, whether radio resource is assigned to traffic of the decided RNT is checked(S130). If the assignment is possible, the RNT is assigned considering a service type of the RNT(S140).
