CONFLICT RESOLUTION FOR PROTOCOL DATA UNIT SESSION REGISTRATION AND DE-REGISTRATION

摘要

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 receiving, at a network function in a communication network, a request to establish a protocol data unit (PDU) session for a mobile station, wherein the request includes an identifier of the PDU session, making a determination that the identifier matches an identifier of an existing PDU session and that the identifier is not for a multi-access PDU session, and initiate, based on the determination, a release of the existing PDU session towards a session management function in the communication network, wherein the release includes an indication that the session management function is not to send a corresponding de-registration request to a unified data management function in the communication network.
