1. A method of a Mobile Station (MS) receiving Multicast Broadcast Service (MBS) in a wireless communication system, the method comprising:
- receiving a Dynamic Service Addition (DSA) message through a primary carrier, from a Base Station (BS);
switching from the primary carrier to a secondary carrier based on the DSA message;
receiving an MBS Configuration message through the secondary carrier, from the BS;
receiving MBS data through the secondary carrier based on the MBS Configuration message, from the BS; and
receiving a change indication indicating whether the received MBS Configuration message is identical with or different from an MBS Configuration message received before, and decoding the received MBS Configuration message if the change indication indicates that the received MBS Configuration message has been changed.

13. A base station (BS) for transmitting Multicast Broadcast Service (MBS) in a wireless communication system, the BS comprising:
-
a Radio Frequency (RF) unit configured to transmit and receive radio signals; and a processor connected to the RF unit, wherein the processor transmits a Dynamic Service Addition (DSA) message to a Mobile Station (MS) through a primary carrier, switches from the primary carrier to a secondary carrier based on the DSA message, transmits an MBS Configuration message to the MS through the secondary carrier, transmits MBS data to the MS through the secondary carrier based on the MBS Configuration message; and transmits a change indication indicating whether the transmitted MBS Configuration message is identical with or different from an MBS Configuration message transmitted before.
