Abstract

Methods, apparatus and systems for backward compatible multi-access protocol data unit session (PDU) registration and deregistration are described. One method of digital communication includes establishing, by a session management function operating in a communication network, a PDU session for a wireless device and transmitting, upon successfully establishing the PDU session, a registration request to a network-side function to register a context of a PDU session of the wireless device with the network-side function, wherein the registration request identifies a set of session management functions that includes the session management function.
