User Equipment and System Architecture for Voice over Long Term Evolution via Generic Access |
摘要 |
Some embodiments provide a communication system that includes (1) an evolved packet system (EPS) that includes an evolved packet core (EPC) and several evolved Universal Mobile Telecommunication System (UMTS) Terrestrial Radio Access Network (E-UTRANs) for communicatively coupling a user equipment (UE) to the EPC, where the EPC is not capable of providing circuit switched (CS) services for the UE and (2) a Voice over long term evolution (LTE) via Generic Access (VOLGA) network controller (VANC) communicatively coupling the UE through the EPS to a legacy circuit switched (CS) core network, where the legacy CS core network is capable of providing CS services to the UE.
