Abstract
A method of performing random access procedure in a wireless communication system is disclosed. The present invention includes the steps of receiving a first message transmitted to count the number of user equipments attempting to receive the broadcast/multicast service from a network, transmitting a preamble for a random access to the network, receiving a second message including a user equipment identifier for identifying the user equipment and uplink (UL) radio resource allocation information in response to the preamble from the network, transmitting a third message to the network using the uplink radio resource allocation information, and stopping the random access in case of receiving a contention resolution message from the network.
