1. An apparatus of an access and mobility management function (AMF) configured to provide mobile terminated (MT) data transport in a communication network, the apparatus comprising:
a memory interface to send or receive, to or from a memory device, a protocol data unit (PDU) session identifier (ID); and
a processor to:
process a non-access stratum (NAS) message and the PDU session ID from a session management function (SMF), the NAS message comprising downlink data from a function in the communication network;
