Claim 8:
9. A non-transitory computer readable medium having stored thereon executable instructions that when executed by a processor of a computer control the computer to perform steps comprising:
receiving, by a NEF from a session management function (SMF), a protocol data unit (PDU) session event change notification message associated with a UE;
establishing, by the NEF, a data delivery path between the UE and an application function (AF) via one of a plurality of data delivery planes that traverse the NEF in response to the PDU session event change notification message, wherein the plurality of data delivery planes includes a non-IP data delivery (NIDD) based data communication path established in a control plane between the UE and the AF via the NEF, an NIDD based data communication path established between the UE and the AF via the NEF and a UPF that are communicatively connected using an N6 point to point tunnel, and an Internet protocol (IP) data delivery based data communication path between the UE and AF that are communicatively connected via the NEF and the UPF using an N6 interface, wherein the NEF is configured to initiate listening servers to monitor for packet traffic from a UPF in response to receiving the PDU session event change notification message and based on a UPF in a data delivery path of the PDU session event change notification message; and
processing, by the NEF, messages communicated between the UE and the AF via the NEF over any of the plurality of data delivery planes using a single unified N33 interface supported by the NEF.
