METHOD FOR REQUESTING EMERGENCY SERVICE AT MOBILE STATION IN A WIRELESS COMMUNICATION SYSTEM

摘要

A method for requesting an emergency service to a base station and a mobile station using the same are disclosed. During initial network entry, a mobile station may transmit an emergency message to a base station using an emergency Flow Identifier (FID), and receive from the base station information about resources allocated according to a default service flow parameter predefined for the emergency service by the base station. The mobile station may transmit to the base station a ranging request message including an emergency service indicator indicating an emergency service request, and receive from the base station a ranging response message including an emergency FID allocated by the BS as a response to the emergency service request. The emergency FID is the emergency FID received in the ranging response message. If the default service flow parameter is not predefined for the emergency service, the mobile station may establish an emergency service flow by a Dynamic Service Addition (DSA) transaction with the base station.
