1. A method for receiving a broadcasting service in a user equipment (UE) in a mobile communication system where requested broadcasting services are provided to a plurality of UEs within a cell through a radio network controller (RNC), the method comprising the steps of:
- receiving a broadcasting status message containing information for ongoing broadcasting services by the cell from the RNC and determining whether the broadcasting service is included in the broadcasting status message in a UE that fails to receive control information for the broadcasting service;
requesting the control information for the broadcasting service to the RNC if the broadcasting service is included in the broadcasting status message; and
receiving the broadcasting service is included in the broadcasting status message after receiving the control information from the RNC.

Abstract
A control message transmitting/receiving method in an MBMS-supporting mobile communication system. In the present invention, an RNC periodically transmits control messages related to MBMS RB setup to UEs. Thus, although a UE initially fails to receive an intended MBMS service, it can set up an MBMS RB by receiving a related retransmitted control message. Also, the RNC periodically provides information about ongoing MBMS services on a cell basis so that a UE can decide whether its requested MBMS service is in progress and request information required to set up an MBMS RB for the MBMS service to the RNC by individual signaling.
