Abstract: According to an embodiment of the present invention, provided are a method for providing a broadcast service of an MBMS coordination entity (MCE) in a mobile communication system, and an MCE for performing the same. The method comprises the steps of: transmitting a terminal counting request message to at least one base station in a multicast-broadcast single frequency network (MBSFN) area; receiving a counting result message comprising the number of terminals receiving a multimedia broadcast multicast service (MBMS) session for each cell of the base station from the base station; and determining MBMS resource allocation for each cell in the MBSFN area on the basis of the counting result message. In addition, it is possible to provide a base station and a terminal operating together with the MCE, and a method for the operation thereof.

Abstract: The terminal supporting the public safety service based on the evolved multimedia broadcast multicast services (eMBMS) service needs to reselect a frequency providing the eMBMS service in the idle mode. The terminal may be configured to: receive a connection release message including priority information on frequencies for cell reselection; determine whether the terminal is in the idle mode; and perform, if the terminal is in the idle mode, cell reselection by selecting a cell to camp on based on the priority information. Here, the priority information may be configured so that the highest priority is assigned to the MBMS serving frequency used by the terminal to receive the MBMS service. In this way, the terminal supporting the public safety service may continuously receive the public safety service by selecting the current frequency during cell reselection.
