STATE MANAGEMENT METHOD OF A MOBILE TERMINAL FOR MULTICAST SERVICES

摘要

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).
