Claim:
A method for transmitting and receiving data by a user terminal in a communication system, the method comprising the steps of: receiving, from a base station supporting a plurality of communication services, an identifier of the base station; determining whether a dedicated random access channel of a communication service preferred by the user terminal, from among individually dedicated random access channels for each subframe to which each of the communication services is mapped, is scheduled; if the dedicated random access channel is scheduled, transmitting, to the base station, a random access message over the dedicated random access channel; if the dedicated random access channel is not scheduled, transmitting the random access message over a shared random access channel available regardless of a type of communication service provided by the base station; and receiving, from the base station, resource allocation information for a resource allocated to the user terminal based on the random access message; wherein the random access message includes the communication service preferred by the user terminal.
