摘要

A core network receives data from at least one of an Application Function (AF), a Data Network (DN), or a User Equipment (UE). A Session Management Function (SMF) processes the data for transport with a low overhead as a session management (SM) payload over a Non Access Stratum (NAS) protocol. The data may be received from an AF or DN external to the core network and may be processed to transport the data to the UE based as a SM payload. The data may be received as uplink data from a UE, e.g., in an SM payload. The SMF may processed the SM payload to obtain the data and may transport the data to the AF or DN. The SMF may perform IP header compression, data encryption based on an SMF encryption key, and/or buffering of data for a UE in an idle mode.
