Abstract: Methods and apparatuses for redirecting a wireless transmit/receive unit (WTRU) to a dedicated core network (CN) node are described. An apparatus is configured to initiate a Service Request with a non-dedicated network node. The apparatus is configured to receive a special identifier in response to the Service Request, which indicates the apparatus should be redirected to a dedicated CN node based on subscription information. Radio access network resources associated with the apparatus may be released and the apparatus may then perform a tracking area update (TAU) request which is then forwarded to the dedicated CN node.

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.

The attachment may be reestablished according to the MuSe functionality. A group communication bearer may have a first priority level for allocating resources to the group communication bearer, and a second priority level for allocating resources to the non-group communication bearer. The second priority level may be different from the first priority level.
