  • Patent number: 11166334
    Abstract: 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.

  • Publication number: 20210266254
    Abstract: Systems, devices, and methods for addressing one or more approaches to path based forwarding is described. A packet frame format for a suitable layer may be used for the delivery of layer 2 packets across User Plane Functions (UPFs). Forwarding the packet frame format from an originating source wireless transmit receive unit (WTRU) over a first UPF to a second UPF, where the second UPF may then send the packet to a destination WTRU. The forwarding may be achieved by suitably swapping information for link-local layer 2 delivery at traversing UPFs. Further, path computation may be performed for registered layer 2 and above services in layer 2 forwarding. Also, forwarding HTTP/IP-over-ICN use cases for HTTP/IP communication over 5G native L2 bearer may be implemented.

  • Publication number: 20210259043
    Abstract: Current wireless networks do not allow machine type communication (MTC) devices to have long discontinuous reception (DRX) cycles or sleep lengths. A long DRX cycle may allow MTC systems and devices to operate with much longer DRX/Sleep cycles/periods. This may facilitate the MTC operations for infrequent system access or infrequent system reaching (e.g. paged once in a week) with no or low mobility and may allow MTC devices to sleep for a long time with low power consumption.
