Based on three emergency call architecture models proposedby IETF Erict Working Group, how the models could be mapped on the WiMAX architecture is analyzed. Based on the WiMAX specific characteristics, such asLBS,we select the combined Model 2 and Model 3 as the best emergency service solution inWiMAX.At the end, some other key considerations are presented, such as emergency call in roaming case and unauthenticated emergency call.
