  • Patent number: 10945302
    Abstract: Circuit switched fallback (CSFB) requests may be managed. A mobile management entity (MME) can detect one or more pending CSFB requests. In response to detecting the pending CSFB request(s), the MME can generate a message that indicates the one or more pending CSFB requests, and can communicate the message to one of a mobile switching center (MSC) and a virtual location register (VLR).

  • Publication number: 20200404734
    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: 20200389827
    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.

  • Patent number: 10856221
    Abstract: A wireless transmit/receive unit (WTRU) is configured to receive at least three sets of parameters associated with power saving. A first set of the parameters is associated with an idle state. A second set of the parameters is associated with a connected state. A third set of the parameters is associated with not being in a connected state and remains registered with a network and maintains a packet data network (PDN) connection. The WTRU is configured to enter active times based on the third set of parameters on a condition that the WTRU is not in the connected state and remains registered with the network. During the active times, the WTRU is configured to monitor physical downlink control channels (PDCCHs) for paging messages.

  • Publication number: 20200267616
    Abstract: Methods, apparatus and systems using Enhanced Dedicated Core Network (DCN) selection are disclosed. One representative method includes receiving, by the core network entity from another core network entity, information indicating that a DCN type is new or has change for a wireless transmit/receive unit (WTRU); and sending a message, by the core network entity to the WTRU, including a new or a changed DCN type.

  • Publication number: 20200178196
    Abstract: 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.

  • Patent number: 10536919
    Abstract: A method and apparatus are described for processing service layer detach commands and attach notifications. A services capability server (SCS) may request a core network to perform a network initiated detach of a device. This procedure may be used when the SCS knows that the device will not be needed for a long time or when the SCS detects some event that may warrant a detach, (e.g., theft, disallowed location, integrity validation failure). The SCS may be asked if the device may be allowed to attach at this time. If the SCS indicates that the attach may be rejected, the device may not be allowed to attach until a later time, thus avoiding additional activity on control and user planes. The SCS may be informed when a device is attached based on various subscription fields stored in a home subscriber server (HSS).

  • Patent number: 10531366
    Abstract: Disclosed herein are embodiments for Machine Type Communication (MTC). The techniques disclosed may reduce signaling by transmitting MTC data over control planes and avoiding a full cycle of connection procedures typically required for transmission. MTC data may be directly appended to a control plane message. In addition, in order to reduce the signaling load, a WTRU may autonomously release the connection without being told by the network. Techniques may be used to indicate a network provider's machine type communication (MTC) capability. The MTC services or capabilities that may be provided by a respective network operator may be communicated to a WTRU.

  • Publication number: 20190349852
    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.

  • Publication number: 20190124508
    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.

  • Patent number: 10231216
    Abstract: Methods and apparatus are described for transmitting and receiving data by a wireless transmit/receive unit (WTRU) over the control plane. The methods may receive data without the use of an Internet Protocol (IP) address. In an example method, a WTRU may enter an evolved packet system (EPS) mobility management (EMM)-registered control plane only (CPO) state after receiving an attach accepted message for CPO operation, and enter an EMM-deregistered state after receiving a detach message, a tracking area update (TAU) reject message or an attach reject message. In another method, a WTRU may switch between operational modes that use an IP address and a user plane to transmit and receive data, and the CPO mode.
