Abstract: A method comprises: at user plane functions (UPFs) of a network, creating a multicast group of the UPFs to enable inter-UPF communication between the UPFs in a multicast domain and, by each UPF: exchanging messages with peer UPFs of the UPFs in the multicast domain to learn peer attributes of the peer UPFs; reporting the peer attributes of the peer UPFs to a session management function (SMF) of the network; and at the SMF, selecting, for a data session, particular UPFs of the UPFs to be configured into a UPF chain of a data path for traffic from user equipment to a data network, based on the peer attributes of the peer UPFs as reported by the UPFs.

Abstract: Providing overload protection may include receiving, from a first NRF of two or more NRFs, a load metric and comparing the load metric to a threshold. Additionally, when the load metric is above the threshold, providing NRF overload protection may include sending a Network Function (NF) Discovery (NFD) message to a second NRF instead of the first NRF and sending a heartbeat signal to the first NRF.

Abstract: In one aspect, a method includes receiving, a serving gateway of a core network of a wireless communication system, a call request associated with an emergency service; assigning a Tunnel Endpoint Identifier (TEID) to the call, wherein the TEID has a plurality of bits and a first segment of the plurality of bits are set to identify the TEID as being associated with the emergency service; and establishing the call for the emergency service with a Packet Data Gateway (PGW) of the core network using the TEID, wherein the TEID enables the PGW to suppress deletion of a bearer associated with the call.
