A mobile communication system supporting an MBMS service includes a Node B having a plurality of transport channels and at least one UE communicating with the Node B. The Node B selects a transport channel for MBMS control information among a plurality of transport channels mapped to a secondary common control physical channel; transmits a system information block indicating the selected transport channel to a cell area where UEs are located, using a primary common control physical channel; and transmits the MBMS control information to the cell area using the selected transport channel. The UE receives a system information block indicating a transport channel selected to transmit MBMS control information among a plurality of transport channels mapped to a secondary common control physical channel, over a primary common control physical channel; receives the MBMS control information over the selected transport channel among the plurality of the transport channels, using the system information block; and receives the MBMS service using the MBMS control information.
