Abstract
This disclosure is related to a procedure of selecting an access stratum to send MT SMS when the UE (100) is registered to the core network via more than one access network.
Claims4
A method for communication in an Access and Mobility Management Function (AMF), the method comprising;
- receiving a Mobile Terminated Short Message Service (MT SMS) message from a Short Message Service Function (SMSF) to transmit to the User Equipment (UE);
- transmitting a Short Message Service (SMS) via a non-3rd Generation Partnership Project (3GPP) access using the SMS over a Non-Access Stratum (NAS) procedure to transmit a MT SMS in response to the AMF determining that the UE is in 5th generation Mobility Management (5GMM)-IDLE mode over a 3GPP access and 5GMM-CONNECTED mode via the non-3GPP access;
- and
- transmitting, in response to the AMF determining that the UE is in 5GMM-CONNECTED mode with a Radio Resource Control (RRC) Inactive indication over the 3GPP access and that the UE is in 5GMM-CONNECTED mode via the non-3GPP access in the AMF, the SMS via the non-3GPP access using the SMS over NAS procedure to transmit the MT SMS.

A method for communication in a User Equipment (UE), the method comprising:
- performing registration to an Access and Mobility Management Function (AMF) via a non-3rd Generation Partnership Project (3GPP) access and a 3GPP access;
- and
- receiving a Short Message Service (SMS) via the non-3GPP access using the SMS over a Non-Access Stratum (NAS) procedure to receive a Mobile Terminated Short Message Service (MT SMS) message in a case where the UE is in 5th generation Mobility Management (5GMM)-IDLE mode over the 3GPP access and 5GMM-CONNECTED mode via the non-3GPP access,
- wherein the UE is in a Mobile Initiated Connection Only (MICO) mode over the 3GPP access, and
- wherein the SMS over NAS procedure is used to transfer the MT SMS message from a Short Message Service Function (SMSF) to the UE.
