Abstract
When a user equipment accessing an access network transmits an emergency call initiating request message to an E-CSCF, the E-CSCF transmits a message requesting for retrieving a current location of the user equipment to a location retrieval unit and the location retrieval unit measures the current location of the user equipment using the access network and transmits a message including the measured location information to the E-CSCF. Then, the E-CSCF establishes a communication channel between the user equipment and an emergency center corresponding to the current location information of the user equipment using a location service response message. Accordingly, it is possible to efficiently provide an emergency location service regardless of structures of networks.
