  • Publication number: 20230354457
    Abstract: 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 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.

  • Publication number: 20230308840
    Abstract: Systems, methods, and instrumentalities associated with providing and/or receiving a multicast-broadcast service (MBS) in a wireless communication system are described herein. A network relay may be used to facilitate the provision of the MBS to a remote wireless transmit/receive unit (WTRU). The network relay may request network authorization to join the MBS on behalf of the remote WTRU. The network relay may include an identifier of the remote WTRU and information regarding the multicast group that the remote WTRU desires to join in the authorization request. The network relay may inform the remote WTRU about an authorization response received from the network, and may forward MBS traffic to the remote WTRU if authorization is granted. The network relay may broadcast an MBS relay support indication to one or more remote WTRUs. The network relay may receive a group paging monitor request from a remote WTRU and may monitor group paging messages for the remote WTRU in response.

  • Patent number: 11737019
    Abstract: 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.

  • Patent number: 11716661
    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.

  • Publication number: 20230199594
    Abstract: A method addressing handover procedure failure or cancellation includes receiving, by a remote wireless transmit/receive unit (WTRU) connected to a source NodeB, a handover command to begin a handover procedure to establish a connection with a target NodeB on a network. A method may further include, on a condition that the handover procedure fails, transmitting, by a relay TRU, a handover failure/cancellation indication to the remote WTRU and cancelling, by the remote WTRU, the handover procedure. A method may also include initiating, by the remote WTRU, a radio resource control (RRC) re-establishment procedure to connect with the source NodeB or a new NodeB.

  • Publication number: 20220345894
    Abstract: Methods and apparatuses are described herein for registration and security for wireless transmit/receive units (WTRUs) with multiple universal subscriber identity modules (USIMs). Optimized registration and authentication procedures, that enable a WTRU to register and authenticate multiple USIMs during one registration and authentication procedure are described herein. The techniques described herein may eliminate the need for separate registration and authentication procedures for each USIM. A gateway device may inform the network in a Registration Request message that it is registering multiple devices (i.e., multiple WTRUs). The network and the gateway may then perform an authentication procedure with an aggregate challenge/response (i.e., a single challenge for each WTRU). A WTRU may inform the network in a Registration Request message that it is registering multiple USIMs. The network and the WTRU may then perform an authentication procedure with an aggregate challenge/response (i.e.

  • Patent number: 11438953
    Abstract: 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.

  • Publication number: 20220264522
    Abstract: A method for use in wireless transmit/receive unit (WTRU) which assesses both a first network and a second network to receive radio frames from each of the first network and the second network is disclosed. The method comprise: obtaining a first paging occasion (PO) as the first network's current PO and a second PO as the second network's current PO; determining whether there is a PO collision between the first PO and the second PO, on condition that there is the PO collision, selecting a network from the first network and the second network, and sending a request to the selected network; receiving, from the selected network, a collision avoidance parameter corresponding to the request; calculating a third PO for the selected network using the collision avoidance parameter, and using the third PO as the selected network's current PO.

  • Publication number: 20220256342
    Abstract: 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.
