Abstract
A method is disclosed of processing emergency call transfer requests by an entry server of an IMS core network. The method includes configuring a table associating at least one emergency call session transfer number with a plurality of emergency call session transfer nodes, each node being identified in the table by an address. Upon receiving a request to transfer an emergency call session from a first access network to a second access network, the request including an emergency call session transfer number, the table is used to determine at least one address of a transfer node associated with the transfer number contained in the request to transfer the request. The transfer request is then sent to the at least one determined address.
