Abstract

The present invention relates to a method and device for receiving a multimedia broadcast multicast service (MBMS) in a mobile communication system. The method for receiving the MBMS of a terminal in the mobile communication system according to an embodiment of the present invention is characterized in that it includes: determining whether service area ID (SAI) information on a serving cell is broadcast during the MBMS; receiving the SAI information on the serving cell when it is determined that the SAI information is broadcast; determining, by using the received SAI information of the serving cell, whether an SAI of the MBMS matches the SAI of the serving cell; and changing the cell reselection priority of the frequency of the serving cell to the highest priority if it is determined that the SAI of the MBMS matches the SAI of the serving cell. According to the present invention, it is possible to efficiently receive MBMS services by enabling a terminal to select a proper frequency or cell when an MBMS service of interest starts.

obtaining MBMS information including at least one MBMS service area identifier (SAI);
receiving a service area identifier (SAI) of a serving cell through a system information block (SIB);
determining whether the SAI of the serving cell corresponds to an MBMS SAI included in the MBMS information;
configuring a cell reselection priority of a frequency corresponding to the SAI of the serving cell to a highest priority if the SAI of the serving cell corresponds to the MBMS SAI included in the MBMS information, and
performing cell reselection based on the cell reselection priority in a radio resource control (RRC) idle state.
