Abstract  Abstract

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