    Abstract: A method performed by a wireless transmit receive unit (WTRU), of receiving a mobile terminated (MT) transmission using an ambient Internet of Things (IOT) service (AIS) is described. The method includes the WTRU receiving an activation signal from a radio access network (RAN) node and harvesting energy. The WTRU determines a format of the received activation signal and based on the format of the activation signal, determines to begin an MT Data procedure with the network. The WTRU receives system information broadcasted by the RAN node and determines to continue the MT data procedure with the network. The WTRU transmits a MT data request message to the RAN node; and receives a MT data container message from the RAN node. The MT data request may include an RRC part and NAS part. The MT data request may include a device identifier and an AIS ID.

    Abstract: An overall architecture to integrate multicast and broadcast service into a general 5G core network. The architecture may provide methods and systems to switch the delivery mode of transmitting messages to User Equipment (UE)s from a unicast mode to a multicast mode. The method includes triggering events at UE, network functions, content provider or RAN node to initiate the switch process; a procedure for UE initiated switch from unicast to multicast; a procedure for network-initiated switch from unicast mode to multicast mode; and a procedure for RAN initiated switch from unicast mode to multicast mode. The architecture may also provide methods to switch the delivery mode from multicast mode to unicast mode. These methods may include triggering events at UE, network functions, content provider or RAN node to initiate the switch process; a procedure for UE initiated switch from multicast mode to unicast mode; a procedure for network-initiated switch from multicast mode to unicast mode; and a procedure for RAN initiated switch from multicast mode to unicast mode.

    Abstract: Procedures, methods, architectures, apparatuses, systems, devices, and computer program products for a wireless transmit/receive unit (WTRU) to determine slice availability in tracking areas (TAs) of a registration area (RA). In a representative example, the WTRU may use determined slice availability to detect changes in slice availability among different TAs. For example, the WTRU may move from a first TA of a RA where access to a first slice is unavailable to a second TA of the RA where access to the first slice is available. The WTRU may receive information during a registration procedure in the first TA that indicates the first slice is available in less than all TAs of the RA. Upon moving to the second TA, the WTRU may (e.g., again) perform a registration procedure in the second TA of the RA in order to access the first slice in the second TA.

    Abstract: A wireless transmit/receive unit (WTRU) may receive parameters associated with a plurality of personal Internet of Things (IoT) network (PIN) gateways (GWs) connected to a PIN. The received parameters may comprise a PIN element type and one or more PIN policy parameters for each of the plurality of PIN GWs. The WTRU may determine a priority for each of the plurality of PIN GWs using the PIN element types and the one or more PIN policy parameters. The WTRU may generate, using the determined priorities, a prioritized list of PIN GWs available on the PIN. The WTRU may receive a connection request from a PIN element connected to the PIN. The WTRU may select one of the plurality of PIN GWs for the PIN element to use to establish connection to the core network.

    Abstract: A wireless transmit/receive unit (WTRU) may send to a network node a registration request message requesting to register with the network and indicating that the WTRU is capable of preserving, when the WTRU becomes unavailable to the network, context information associated with the communications between the WTRU and the network. The network node may indicate in a registration accept message that the network supports the preservation of context information when the WTRU becomes unavailable to the network. Based on a determination that the WTRU will become unavailable to the network, the WTRU may send to the network a message indicating a request to preserve the context information. The message may comprise an indication of a time period during which the WTRU will be unavailable.

    Abstract: A network node, e.g., an edge configuration server (ECS), associated with a first PLMN may receive a first message from a WTRU. The first message may indicate a request to be notified if a type of network node, e.g., an ECS, becomes available to be accessed by the WTRU. The network node may receive a second message from a second network node. The second message may indicate an identity of a second PLMN and may indicate that the WTRU has become registered with the second PLMN. The network node may determine that a third network node of the type of network node, e.g., an ECS, is available to be accessed by the WTRU in the second PLMN. The network node may determine local breakout (LBO) information for the WTRU to establish a LBO packet data unit (PDU) session in the second PLMN and access the third network node.

    Abstract: The device may be a multi-universal subscriber identity module (MUSIM) device. The device may send a first registration request to a first network, for example, to enable an unavailability period feature with the second network. The registration request may indicate a first unavailability duration. The device may determine that an unavailability event is triggered. The device may determine that the device will be unavailable for a period of time. The device may receive a first registration response, for example, a first registration accept message. The first registration response may indicate a first registration duration. The device may determine a second unavailability duration. The device may send a second registration request to a second network, for example, indicate the second unavailability duration. The device may receive a second registration response. The second registration response may be a second registration accept message. The second registration response may indicate a second registration duration.
