1. A method to be performed at an access and mobility management function (AMF) configured to provide mobile terminated (MT) data transport in a communication network, the method comprising:
processing a non-access stratum (NAS) message and a protocol data unit (PDU) session identifier (ID) from a session management function (SMF), the NAS message comprising downlink data from a function in the communication network;
generating an integrity protected and encrypted downlink NAS transport message comprising the PDU session ID and the NAS message from the SMF; and
forwarding the downlink NAS transport message to an access node for delivery to a user equipment (UE) associated with the PDU session ID;
wherein the PDU session is of an unstructured type, reliable data service (RDS) is enabled, and wherein the downlink NAS transport message includes an indication that RDS acknowledgement is requested.
