Method of transmitting/receiving control message in a mobile communication system providing multimedia broadcast/multicast service
First Claim
1. A method for providing a Multimedia Broadcast/Multicast Service (MBMS) to a User Equipment (UE) in a radio access network in a mobile communication system, the method comprising the steps of:
- transmitting a first message including information about a scheduling period and an offset indicating a start point of the scheduling period to the UE;
repeatedly transmitting a second message including information about ongoing MBMSs to the UE in every scheduling period, according to the information about the scheduling period and the offset; and
transmitting data of at least one of the ongoing MBMSs to the UE via an MBMS Radio Bearer (RB) established for the at least one of the ongoing MBMSs,wherein the information about the ongoing MBMSs includes service IDentifications (IDs) of the ongoing MBMSs.

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.
