摘要： Systems, methods, and instrumentalities are provided for a network control node for connecting a wireless transmit/receive unit (WTRU) to a network slice in a network. The network control node may receive service information associated with a service being requested by the 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, wherein the slice information comprises one or more of an identifier of the network slice, priority of the network slice, a service class served by the network slice, a target device class, a QoS target, mobility support, security service, charging information, and/or performance information. The network control node may determine subscriber information for the WTRU. The network control node may select at least a first network slice of the plurality of network slices to serve the WTRU, wherein the network control node selects the first network slice based on the service information, the slice information associated with the first network slice, and the subscriber information for 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. On condition that the network control node determines that the network control node should service the WTRU for accessing the first network slice, the network control node may provide at least one network service associated with the first network slice to the WTRU. Or, on condition that 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.

摘要： A network may implement a method to support a mobility of a wireless transmit/receive unit (WTRU). The network or network functions may identify the WTRU that is associated with one or more capabilities and one or more mobility properties. The network or network functions may determine subscription information and network policy information for the WTRU. The network or network functions may select a mobility pattern for the WTRU based on the one or more capabilities and the one or more mobility properties associated with the WTRU, the subscription information, and the network policy information. The mobility pattern may be associated with a mobility parameter and a value corresponding to the mobility parameter.

摘要： Methods, apparatuses, systems, etc. for handling mobility in connection with protocol data unit (PDU) sessions are provided. Among these is a wireless transmit/receive unit (WTRU) that may receive, from a source access network (S-AN), a handover command in connection with a handover involving a multi-access protocol PDU (MA-PDU) session having one of first and second access legs associated with the S-AN. The WTRU may determine that the second access leg should be associated to the S-AN for the handover. The WTRU may send a session modification message to request modification of the MA-PDU session to cause the second access leg to become associated with S-AN The WTRU may establish a radio resource control connection with a target AN (T-AN), and the first and second access legs (e.g., as a combined access leg) may be associated with the T-AN.

摘要： A system and apparatus for addressing the different types of mobility of a wireless transmit/receive unit (WTRU) in a network. A radio access network (RAN) may send a request for configuration information to a gateway device including a device ID of a WTRU, a service ID, and a RAN address. Once the RAN receives configuration information from the gateway device including a forwarding table, the RAN may be prepared to receive non-IP data from a WTRU including a routing tag. The routing tag may be based on the device ID of a WTRU and service ID. The RAN may transmit the non-IP data received from the WTRU to the gateway device over a routing path based on the routing tag and a forwarding table where the non-IP data is forwarded on to its detention, such as another WTRU or an Application Server.

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： 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： Systems, methods, and instrumentalities are disclosed that are associated with cellular communications for unmanned aerial vehicles and associated devices. A WTRU may initiate multiple PDU sessions. The WTRU may initiate a first protocol data unit (PDU) session. The WTRU may receive one or more session parameters for a second PDU session. The one or more session parameters for the second PDU session may be received via the first PDU session. The WTRU may initiate the second PDU session using the one or more session parameters (e.g., based on an authentication and authorization associated with the first PDU session being successful). The WTRU may send or receive an operation communication via the second PDU session. The operation communication may comprise an unmanned aerial vehicle command and control message or an unmanned aerial vehicle payload message.
