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 3GPP access leg and non-3GPP access leg in 5GC, and the WTRU may replace the 3GPP 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 3GPP access leg in EPC.

摘要： A user equipment, WTRU (401), may be provisioned on a stand-alone non-public network, SNPN. The WTRU registers with an on-boarding network, ONN (402). An indication that the WTRU is requesting to register with the ONN is received by a provisioning server, PVS (403), of the SNPN. An identifier associated with the WTRU is transmitted to the PVS. The PVS requests to subscribe to notifications related to the provisioning. For example, the notifications are sent/received via a network exposure function, NEF. A notification that the WTRU has successfully registered with the SNPN is transmitted (e.g., to the devices the requested to subscription notifications). After the WTRU has been successfully registered, the WTRU is de-registered from the ONN, and an indication that the WTRU has been de-registered from the ONN is transmitted (e.g., via the NEF).

摘要： A WTRU may initiate access for a PDU session over multiple access networks. The WTRU may register with two or more access networks. For example, the WTRU may register with a 3GPP access network (e.g., LTE Advanced) and a non-3GPP access network (e.g., Wi-Fi). The WTRU may determine to request a multi-access PDU session for a (e.g., at least one) PDU session. A multi-access PDU session may correspond to a PDU session where the WTRU communicates one or more PDUs associated with the PDU session over the 3GPP access network and one or more PDUs associated with the PDU session over the non-3GPP access network. The WTRU may receive a confirmation message indicating that a multi-access PDU session has been established. The WTRU may send uplink data over the 3GPP access network and the non-3GPP access network, e.g., in accordance with the established multi-access PDU session.

摘要： One or more systems, devices, and/or methods may address approaches and use techniques described herein to onboard a device when the device does not have a predetermined home network. The device may indicate, explicitly or implicitly, that it does not have a home network to an onboarding network. The onboarding network may authenticate the device, then provide the device with a provisioning server address. The onboarding network may initiate a unified data management service, and provide the provisioning server with a temporary identifier for the device. The device may establish a connection with the provisioning server, and provide the temporary credentials to the device. The device may use the temporary credentials to register with the onboarding network.

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： 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.

摘要： Procedures, mechanisms, methods, and techniques are provided that trigger power saving mode (PSM) functionality in the at least one wireless transmit receive units, group of WTRUs or subset of the group of WTRUs. The trigger may be in response to an application layer request to set one or more predetermined PSM settings, wherein the trigger originates from one or more application servers (APs) directed to a core network by way of an interface such as an SCEF that may be included on a device (e.g., a gateway, computing device, and/or the like) and may be configured for enabling the application server to request enabling and disabling PSM functionality.

摘要： A method of communicating using proximity services (ProSe) is disclosed. A base station receives at least one aggregate maximum bit rate (AMBR) parameter from a network entity. The at least one AMBR parameter comprises a maximum bit rate that a first wireless transmit/receive unit (WTRU) can use for data sent on one or more ProSe bearers. The base station receives a request from the first WTRU to establish the one or more ProSe bearers with a second WTRU. The request comprises priority information of the one or more ProSe bearers determined by the first WTRU. The base station sends an indication to the first WTRU to establish a ProSe communication over the one or more ProSe bearers based on at least the AMBR parameter and the priority information of the one or more ProSe bearers.

摘要： A wireless transmit/receive unit (WTRU) may receive from a network resource allocation information for device to device (D2D) communication. The WTRU may select, from the received resource allocation information for a transmission time interval (TTI), resources for a D2D channel. The WTRU may transmit, with use of the selected resources, data directly to another WTRU.
