An apparatus and a method for changing a Multicast and Broadcast Service (MBS) channel of a terminal in a broadband wireless communication system are provided. In the method, an overall channel scheduling information message comprising group information for Connection Identifications (CIDs) of all channels in service is received from a base station. Transmission information of an MBS channel scheduling information message corresponding to a group to which a CID of a current channel belongs is extracted from the overall channel scheduling information message. A relevant MBS channel scheduling information message is received from the base station using the extracted transmission information of the MBS channel scheduling information message. Transmission information of an MBS MAP message for a relevant CID is extracted from the MBS channel scheduling information message. Therefore, an MBS channel change of a terminal can be easily performed.
