1. A method for transmitting an emergency service message at a Base Station (BS) in a wireless communication system, the method comprising:
- allocating a Connection IDentifier (CID) used to transmit an emergency service message;
determining a Convergence Sublayer (CS) type for processing the emergency service message;
generating a Downlink Channel Descriptor (DCD) message which comprises at least one of the allocated CID and information relating to the determined CS type; and
transmitting the generated DCD message to a Mobile Station (MS).

8. A method for transmitting an emergency service message at a Base Station (BS) in a wireless communication system, the method comprising:
-
determining whether there exists an emergency service message to transmit in a Multicast and Broadcast Service (MBS) region; setting a field in an MBS_MAP Information Element (IE) according to the determination, the field indicative of the presence or absence of the emergency service message to be transmitted in the MBS region; and transmitting a DownLink (DL)-MAP message comprising the MBS_MAP IE with the set field to the MS. - View Dependent Claims (9, 10)

16. A method for receiving an emergency service message at a Mobile Station (MS) in a wireless communication system, the method comprising:
-
receiving a Multicast and Broadcast Service (MBS)_MAP Information Element (IE) through a DownLink (DL)-MAP message; confirming setting of a field in the received MBS_MAP IE, the field indicative of the presence or absence of the emergency service message to be transmitted in an MBS region; and when the field setting indicates the existence of the emergency service message to transmit in the MBS region, decoding an MBS MAP message. - View Dependent Claims (17, 18)
