Publication number: 20230397281Abstract: Systems and methods for managing synchronization of protocol data unit (PDU) sessions between a user equipment (UE) and a network are disclosed herein. In some embodiments, a determination of whether a message comprising a PDU session status information element (IE) should be sent is based on previous messaging between peer entities of the network. In some embodiments, a determination that the peer entity is informed of a relevant PDU session status is made after expected reply messaging is received in response to prior messaging. In some cases, a reply message without a PDU session status IE is sent from one entity to a peer entity when it is determined that each entity has a matching PDU session status. Cases involving failures detected at the network, and cases where an entity activates a data radio bearer (DRB) of a PDU session that is inactive at its peer are also discussed.Type: ApplicationFiled: September 3, 2021Publication date: December 7, 2023Inventors: Nirlesh Koshta, Anikethan Ramakrishna Vijaya Kumar, Basant Kumar, Krisztian Kiss, Pradeep Pangi, Sridhar Prakasam
