Abstract
A method for supporting an emergency call in a mobile communication system is provided, which comprises the steps of: receiving, at a radio resource management entity, a message from a UE indicating that there is an emergency call; setup a RRC connection between the UE and the radio resource management entity; transmitting, by the radio resource management entity, a message to its upper-layer node, the message containing an emergency service indication; and establishing, by the upper-layer node of the radio resource management entity, the emergency call for the UE. With the method for supporting an emergency service in a mobile communication system provided in the present invention, the access failure of an emergency service can be reduced, and the access speed of the emergency service can be increased.
