Patent ID: 8655374

Claim:
A method of providing a core network with a current cell location of a User Equipment (UE) operating in a Circuit Switched Services over LTE Generic Radio Access Network having a plurality of LTE cells, so that when the UE registers with a Generic Access Network Controller (GANC), from a first LTE cell of the plurality of LTE cells, the GANC selects a first GAN Cell Global Identifier (GAN-CGI) being associated with a first LTE cell of the plurality of LTE cells for reporting the location of the UE to the core network, the method comprising the steps of: receiving by the GANC, a message from the UE reporting a current cell in which the UE is located whenever one of a group of triggering events is detected by the UE, the group of triggering events including each time the UE performs a tracking area update; selecting by the GANC, a second GAN-CGI associated with a second LTE cell of the plurality of LTE cells if the message indicates that the UE has moved from the first LTE cell of the plurality of LTE cells to the second LTE cell of the plurality of LTE cells; and reporting by the GANC, the second GAN-CGI to the core network.
