Abstract  Abstract

Claims use CS fallback and CSoLTE-I construction in the network used for providing mobile terminal MT and mobile originating MO circuit switched (CS) service (such as short message service (SMS) service method and device. Called SGs + (SGs interface extension of 63) in the SAE core network (11) mobile management entity (MME) (64) and the mobile switching centre server MSC-S (61). SGs + a. is connected by a connection-oriented signalling connection control part SCCP transmission is not supported by the upper-layer CS packet data unit. The non-access layer NAS signalling between the user equipment (UE) (27) and MME (64) support is extended to provide support for MTSMS and MO SMS service.

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+ (63) is implemented between a Mobility Management Entity MME (64) in an SAE core network (11) and a Mobile Switching Center Server MSC-S (61). 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 (27) and the MME (64) is extended to provide support for both MT SMS and MO SMS service.
