Abstract
Systems and methods for efficient delivery of infrequent small data are provided. A system for providing communication infrequent small Protocol Data Units (PDUs) to/from a UE includes an Access Node (AN); a session management functions node; and a User Plane (UP) functions entity. The session management functions node receives a session setup request and selects the UP functions entity and a tunnel identifier associated with the UE. In case of an IP PDU session type, trigger an establishment of a UP. The UP functions entity creates a UE context for the UE; stores the UE context for the UE; completes an establishment in a Control Plane (CP); and provides the AN with uplink tunnel information. The AN stores the UE context and transmits a session setup response to the UE. In this way, an improved ratio of the signalling/user data relation may be obtained for devices sending infrequent small data.
