Abstract
A method of providing a circuit switching CS service to a User Equipment, UE, (27) through an SAE core network and an LTE radio access network, said method comprising the steps of: extension of an SGs interface to provide an SGs + interface (63) between a Mobility Management Entity, MME, (64) in the SAE core network and a Central Mobile Switching Server, MSC-S, (61) in where the SGs + interface supports the transmission of upper layer packet data units; transfer of CS service messages in SGs + messages sent between the MSC-S and the MME through the use of the SGs + interface, where the transfer step of the CS service messages includes sending from the MSC-S to the MME, including a downlink data transfer message SGs + the higher layer packet data units destined for a terminating UE or sending from the MME to the MSC-S, including a uplink data transfer message SGs + the upper layer packet data units originated by a source UE; and transfer of CS service message contents between the MME and the UE through the LTE radio access network in stratum messages without access, NAS, where the CS service is the Short Message Service, SMS , and the CS service message transfer step includes sending from the MSC-S to the MME, a downlink data transfer message SGs +, including said downlink data transfer message SGs + packet data units of SMS control plane and SMS message content destined for the termination UE.
