Patent number: 12133277Abstract: A method and a system are disclosed for providing session continuity in a 5G system. A wireless transmit receive unit (WTRU) may receive, from a session management function (SMF), a first Non-Access Stratum (NAS) message indicating a Packet Data Unit (PDU) session re-establishment. Upon receiving the first NAS message, the WTRU may determine an old PDU session ID based on the NAS message and generate a new PDU session ID. The WTRU may transmit a second NAS message indicating a PDU session establishment request. The second NAS message may include the old and new PDU session IDs. Upon receiving the PDU session establishment request, the SMF may determine that the old PDU session ID is associated with an existing PDU session for which the PDU session re-establishment is requested. The SMF may also determine that the new PDU session ID is associated with a new PDU session to be established.Type: GrantFiled: November 2, 2021Date of Patent: October 29, 2024Assignee: InterDigital Patent Holdings, Inc.Inventors: Guanzhou Wang, Saad Ahmad, Mahmoud Watfa, Ulises Olvera-Hernandez, Xiaoyan Shi, Bartosz Balazinski
