Techniques are described herein for helping the User Plane Function (UPF) to advertise Uplink Classifier (UL-CL), Branching Point (BP), and Protocol Data Unit (PDU) Session Anchor (PSA) functionalities towards the Network Resource Function (NRF) and Session Management Function (SMF) via an N4 interface. Accordingly, the SMF will be able to identify the appropriate UPF to insert UL-CL/BP functionality in the data path and also to better handle Session and Service Continuity (SSC) mode 3 User Equipment (UE). This also helps the UPF to advertise any newly developed functionalities (e.g., Information Centric Networking (ICN)).
