Abstract

Methods are provided to operate an SMF node. A request to create a session for a wireless device is received. A communication establishment request is transmitted to an NEF node responsive to receiving the request to create the session for the wireless device, wherein the communication establishment request includes UPF node information for a tunnel between a UPF node and the NEF node to be used for the session for the wireless device. A communication establishment response is received from the NEF node, wherein the communication establishment response includes NEF node information for the tunnel between the UPF node and the NEF node to be used for the session for the wireless device. A tunnel information update is transmitted to the UPF node after receiving the communication establishment response, wherein the tunnel information update includes the NEF node information for the tunnel between the UPF node and the NEF node.

Description

technical field [0001] The present disclosure relates generally to communications, and more particularly to communications networks and related methods and network nodes / entities. Background technique [0002] 3GPP has initiated the IoT research project for the fifth generation 5G through TR 23.724 (Reference [1]). One issue is how to handle data transfer from the core network to NEF nodes (eg NIDD; non-IP data transfer). Solution 35 in 23.724v1.0.0 is a method when the wireless device UE transmits data through the user plane. In this approach, UPF / NEF is a combined entity, and no specific interface is defined between UPF nodes and NEF nodes. However, such an approach may not provide sufficient flexibility. Contents of the invention [0003] According to some embodiments of the inventive concept there are provided methods for operating a Session Management Function SMF node of a wireless communication network. A request to create a session for a wireless device is rece...
