  • Patent number: 11751276
    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: 20230217365
    Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate and to a method to handle rejected NSSAI area. The method includes receiving a NAS message indicating registration accept or registration reject with a reject cause. The reject cause indicating a S-NSSAI is not available in a subset of a current registration area where the reject cause is applied for a S-NSSAI. In an example, the method includes storing the rejected S-NSSAI in a rejected NSSAI for the subset of the current registration area. In another example, the method includes deleting a current registration area based on the subset of the current registration area where the reject cause is applied for the S-NSSAI. The UE considers a S-NSSAI part of the requested NSSAI as not applicable to current tracking area and S-NSSAI part of the requested NSSAI is allowed outside current tracking area.

  • Publication number: 20230209395
    Abstract: Procedures, systems, and devices for addressing quality of service (QoS) during an inter-system change of a wireless transmit/receive unit (WTRU) are discussed herein. A WTRU may send a packet data unit (PDU) modification request to a network node, such as a session management function (SMF) device, indicating support for reflective quality of services (RQoS). In response to the modification request, the WTRU may then receive an acknowledgment, after which the WTRU may then be able to send data for a PDU of a specific RQoS. The RQoS may be specific to a single PDU or a plurality of PDUs. The modification request may include Session Management (SM) and/or Mobility Management (MM) information. The modification request may be included in an attach procedure or a tracking area update (TAU).

  • Patent number: 11683353
    Abstract: IoT service layer capabilities may be employed to automate and simplify the service enrollment process for IoT service subscribers/enrollees. These capabilities enable virtualization of a service subscriber and the physical IoT devices, applications, data and authorized users of the subscriber into a software profile that is representative of the subscriber. Once virtualized, a service subscriber may then delegate the complexities and burden of service enrollment to an automated IoT service enrollment software function.
