A method for transmitting a traffic indication message for directing a mobile subscriber station (MSS) in a sleep mode to transition to an awake mode in a Broadband Wireless Access communication system supporting the sleep mode and the awake mode. This method includes the steps of individually allocating, to MSSs belonging to a corresponding base station, corresponding areas indicating traffic instructions for the MSSs in a traffic indication field in the traffic indication message, and indicating state transition instructions in the areas allocated to the MSSs, before transmitting the traffic indication message to the MSSs.

What is claimed is: 1. A system for receiving a traffic indication message in a Broadband Wireless Access communication system, the system comprising: a mobile subscriber station (MSS) for receiving the traffic indication message from a base station (BS), wherein the traffic indication message includes sleep identifiers (SLPIDs) and a number of positive indications, a number of the SLPIDs being identical to the number of the positive indications, each of the SLPIDs is uniquely assigned by the BS when a corresponding MSS is instructed to enter a sleep mode, and each of the positive indications represents that traffic is directed to a corresponding MSS. 2. The system of claim 1, wherein the MSS detects whether the SLPID of the MSS is included in the SLPIDs, and determines whether to state transition based on whether the SLPID of the MSS is included in the SLPIDs. 3. The system of claim 2, wherein the MSS state transitions to an awake mode when the SLPID of the MSS is included in the SLPIDs. 4. The system of claim 1, wherein the MSS receives a sleep response message from the BS before receiving the traffic indication message, and the sleep response message includes information on the SLPID of the MSS. 5. A method for transmitting a traffic indication message by a base station (BS) in a Broadband Wireless Access communication system, the method comprising: transmitting the traffic indication message to mobile subscriber stations (MSSs), wherein the traffic indication message includes sleep identifiers (SLPIDs) and a number of positive indications, a number of the SLPIDs being identical to the number of the positive indications, each of the SLPIDs is uniquely assigned by the BS when a corresponding MSS is instructed to enter a sleep mode, and each of the positive indications represents that traffic is directed to a corresponding MSS. 6. The method of claim 5, further comprising: transmitting a sleep response message to the MSS before transmitting the traffic indication message, the sleep response message including information on the SLPID. 7. A method for receiving a traffic indication message by a mobile subscriber station (MSS) in a Broadband Wireless Access communication system, the method comprising: receiving the traffic indication message from a base station (BS), wherein the traffic indication message includes sleep identifiers (SLPIDs) and a number of positive indications, a number of the SLPIDs being identical to the number of the positive indications, each of the SLPIDs is uniquely assigned by the BS when a corresponding MSS is instructed to enter a sleep mode, and each of the positive indications represents that traffic is directed to a corresponding MSS. 8. The method of claim 7, further comprising: detecting whether the SLPID of the MSS is included in the SLPIDs; and determining whether to state transition corresponding whether the SLPID of the MSS is included in the SLPIDs. 9. The method of claim 8, wherein determining whether to state transition corresponding the detecting result comprises state transitioning to an awake mode when the SLPID of the MSS is included in the SLPIDs. 10. The method of claim 7, further comprising: receiving a sleep response message from the BS before receiving the traffic indication message, the sleep response message including information on the SLPID of the MSS. 11. A system for transmitting a traffic indication message in a Broadband Wireless Access communication system, the system comprising: a base station (BS) for transmitting the traffic indication message to mobile subscriber stations (MSSs), wherein the traffic indication message includes sleep identifiers (SLPIDs) and a number of positive indications, a number of the SLPIDs being identical to the number of the positive indications, each of the SLPIDs is uniquely assigned by the BS when a corresponding MSS is instructed to enter a sleep mode, and each of the positive indications represents that traffic is directed to a corresponding MSS. 12. The system of claim 11, wherein the BS transmits a sleep response message to the MSS before transmitting the traffic indication message, and the sleep response message includes information on the SLPID.
