摘要: A method and apparatus for providing both Mobile Terminated, MT, Originated, MO, circuit switched (CS) services such as Short Message Service, SMS, in networks utilizing CS Fallback CSoLTE-I architectures. An extended SGs interface referred to SGs+ is implemented between a Mobility Management Entity, MME, an SAE core network Switching Center Server, MSC-S. The supports transmission of upper layer packet data units while either connectionless or connection-oriented Signaling Connection Control Part, SCCP, operation. non access stratum, NAS, signaling support the User Equipment, UE, MME provide MT SMS MO service.
