摘要： Systems and methods are described herein for enabling service continuity between standalone non-public network (SNPN) and a public land mobile network (PLMN). A wireless transmit/receive unit (WTRU) may enable service continuity, for example, by triggering a temporary leave of the WTRU from a serving SNPN to prepare a pre-established backup user plane (UP) connection in a PLMN. A network may enable service continuity, for example, by triggering a temporary leave of a WTRU from a serving SNPN to prepare a pre-established backup UP connection in a PLMN. A WTRU may switch back to SNPN from PLMN, for example, using an SNPN priority search mode and/or other WTRU behavior(s).

摘要： A wireless transmit/receive unit (WTRU) may establish a multi-access (MA) protocol data unit (PDU) in accordance with the examples described herein. The WTRU may establish a new packet data network (PDN) connection or identify a suitable existing PDN connection in an evolved packet core (EPC), establish a MA-PDU in a 5G core network (5GC), and associate the existing PDN with the MA-PDU. The WTRU may already have a MA-PDU session established in 5GC with both 3GGP access leg and non-3GPP access leg in 5GC, and the WTRU may replace the 3GGP access leg in 5GC with a suitable PDN connection in EPC. The WTRU may send a request for establishing a single-access PDU session in 5GC via non-3GPP access, and a 5GC network may upgrade a PDU session established for the WTRU to a MA-PDU with 3GGP access leg in EPC.

摘要： A method performed by a WTRU may comprise determining application layer information and receiving QoS policy configuration information. A QoS mechanism may be determined based on the application layer information and the received QoS policy configuration information. A QoS value applicable to the determined QoS mechanism may then be determined for a data packet. Subsequently, the determined QoS value may be transmitted to another WTRU over a PC5 interface, with or without the data packet. The QoS mechanism may be determined as one of a PPPP mechanism or a QFI mechanism. The QoS policy configuration information may be received via a gNB. In an embodiment, the application layer information may include an application identifier, a PSID or an ITS-AID. The QoS policy configuration information may indicate a mapping of V2X application IDs to respective QoS mechanisms.

摘要： Coordinated P-GW change for SIPTO may be provided. A WTRU may send and/or receive one or more flows via a first PDN connection and via a first P-GW. The WTRU may send an indication to the network that at least one flow of the first PDN connection is available for SIPTO. The indication may include one or more SIPTO preferences. The WTRU may receive a message from a MME. The message may trigger establishment of a second PDN connection via a second P-GW. The WTRU may move, while maintaining the first PDN connection, the at least one flow from the first PDN connection to the second PDN connection. The WTRU may deactivate the first PDN connection when the one or more flows have been moved to the second PDN connection and/or when no information has been received via the first PDN connection after a predetermined duration.

摘要： Methods, systems, and apparatuses for protocol data unit (PDU) session management over different access technologies (ATs) are disclosed. A wireless transmit/receive unit (WTRU) may receive a first message from a network over a first access technology. The first message may include an indication for the WTRU to reestablish resources for one or more protocol data unit (PDU) sessions over a second access technology. The WTRU may determine that a PDU session of the one or more PDU sessions is locally deactivated by the WTRU. The WTRU may determine that it is in a limited service state associated with the second access technology. The WTRU may send a second message via the first access technology. The second message may include a PDU session status information element (IE) indicating the PDU session is locally deactivated such that the network releases the PDU session.

摘要： Embodiments include methods and apparatuses for providing access to a network slice in a communication system. In an embodiment, a network server that implements a Control Plane (CP) Network Function (NF) may receive a Non-Access Stratum (NAS) message from a wireless transmit and receive unit (WTRU). The NAS message comprises a Mobility Management (MM) message for registration and a Session Management (SM) messages for a specific service provided by the network slice. After selecting the network slice, the network server may transmit the SM message to another CP NF in the network slice to establish a communication link between the WTRU and the network slice.

摘要： A wireless transmit/receive unit (WTRU) may establish one or more protocol data unit (PDU) sessions via a radio access network (RAN) node. The WTRU may transition to an inactive state. The WTRU may send a connection resume message to a RAN node that indicates a request to resume the established plurality of PDU sessions via the RAN node. The WTRU may receive a message from the RAN node. For example, the RAN node may send a message indicating a subset of the plurality of PDU sessions that are available upon resuming a connection with the RAN node. The WTRU may deactivate at least one established PDU session of the plurality of PDU sessions based on the received message from the RAN node that indicates at least one established PDU session not being included in the subset of the plurality of PDU sessions that are available.

摘要： A network control node (Main CTRL or CTRL N) may receive a service request by a WTRU, wherein the service information comprises one or more of a service class, a quality of service (QoS) requirement, or a mobility characteristic. The network control node may determine slice information associated with a plurality of network slices and may select at least a first network slice to serve the WTRU. The network control node may determine whether the network control node or another network control node should service the WTRU for accessing the first network slice. When the network control node determines that the another network control node should service the WTRU for accessing the first network slice, the network control node may send a request to the another network control node that indicates that the another network control node should service the WTRU for accessing the first network slice.
