Method and apparatus for providing emergency communication service in a wireless communication system
First Claim
1. A method for providing an emergency communication service at a Mobile Station (MS) in a wireless communication system, the method comprising:
- receiving a Bandwidth Request (BR) index set for the emergency communication service from a Base Station (BS);
deleting the BR index when the MS transitions to an idle mode, wherein the BR index is changed when the MS performs handover;
transmitting a message requesting the emergency communication service using the BR index to the BS;
receiving a connection setup request message from the BS, the connection setup request message including a Service Flow Identifier (SFID) indicating that a service flow corresponding to the emergency communication service has been generated, a Flow Identifier (FID) between the BS and the MS for providing the emergency communication service, and an indicator indicating a connection request for the emergency communication service;
performing a setup procedure for using the service flow based on the SFID, the FID, and the indicator; and
upon completion of the setup procedure, transmitting a data packet for the emergency communication service to the BS.

Abstract
A method and apparatus providing an emergency communication service in a wireless communication system. A mobile station (MS) transmits a message requesting the emergency communication service to a base station (BS), receives a connection setup request message from the BS, the connection setup request message including a Service Flow Identifier (SFID) indicating that a service flow corresponding to the emergency communication service has been generated, a Flow Identifier (FID) between the BS and the MS for providing the emergency communication service, and an indicator indicating a connection request for the emergency communication service, performs a setup procedure for using the service flow based on the SFID, the FID, and the indicator and, upon completion of the setup procedure, transmits a data packet for the emergency communication service to the BS.

5. A method for providing an emergency communication service at a Base Station (BS) in a wireless communication system, the method comprising:
-
transmitting a Bandwidth Request (BR) index set for the emergency communication service to a Mobile Station (MS), wherein the BR index is deleted when the MS transitions to an idle mode and the BR index is changed when the MS performs handover; transmitting a message requesting generation of a service flow for the emergency communication service to a Base Station Controller (BSC), upon receipt of a message requesting the emergency communication service using the BR index from the MS; and transmitting a connection setup request message to the MS, upon receipt of a message indicating generation of the service flow from the BSC, the connection setup request message including a Service Flow Identifier (SFID) corresponding to the generated service flow, a Flow Identifier (FID) between the BS and the MS for providing the emergency communication service, and an indicator indicating a connection request for the emergency communication service. - View Dependent Claims (6, 7, 8, 9)

10. A Mobile Station (MS) configured to provide an emergency communication service in a wireless communication system, the MS comprising:
-
a transceiver configured to communicate with a Base Station (BS); a controller configured to; control the transceiver to receive a Bandwidth Request (BR) index set for the emergency communication service from the BS, delete the BR index when the MS transitions to an idle mode, wherein the BR index is changed when the MS performs handover, transmit a message requesting the emergency communication service using the BR index to the BS, and receive a connection setup request message from the BS, the connection setup request message including a Service Flow Identifier (SFID) indicating that a service flow corresponding to the emergency communication service has been generated, a Flow Identifier (FID) between the BS and the MS for providing the emergency communication service, and an indicator indicating a connection request for the emergency communication service, perform a setup procedure for using the service flow based on the SFID, the FID, and the indicator, and upon completion of the setup procedure, control the transceiver to transmit a data packet for the emergency communication service to the BS; and a memory configured to store the BR index, the SFID, the FID, and the indicator under control of the controller. - View Dependent Claims (11, 12, 13)

14. A Base Station (BS) configured to provide an emergency communication service in a wireless communication system, the BS comprising:
-
a transceiver configured to communicate with a Mobile Station (MS) and a BS Controller (BSC); a controller configured to; control the transceiver to transmit a Bandwidth Request (BR) index set for the emergency communication service to the MS, wherein the BR index is deleted when the MS transitions to an idle mode and the BR index is changed when the MS performs handover, control the transceiver to transmit a message requesting generation of a service flow for the emergency communication service to the BSC, upon receipt of a message requesting the emergency communication service using the BR index from the MS through the transceiver, and upon receipt of a message indicating generation of the service flow from the BSC, and control the transceiver to transmit a connection setup request message to the MS, the connection setup request message including a Service Flow Identifier (SFID) corresponding to the generated service flow, a Flow Identifier (FID) between the BS and the MS for providing the emergency communication service, and an indicator indicating a connection request for the emergency communication service; and a memory configured to store the BR index, the SFID, the FID, and the indicator under control of the controller. - View Dependent Claims (15, 16, 17, 18)
