  • Patent number: 11956319
    Abstract: 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.

  • Patent number: 11950198
    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.

For example, a wireless transmit/receive unit (WTRU) may receive (e.g., receive from a network) a mapping of physical cell identifications (PCIs) to area identifications (AIDs). The WTRU may determine a first PCI associated with a first neighbor cell. The WTRU may determine, based on the first PCI and the PCIs to AIDs mapping, whether the WTRU is allowed to access the first neighbor cell. The WTRU may perform cell selection or reselection with the first neighbor cell as a cell selection or reselection candidate. The WTRU may perform cell selection or reselection based on the WTRU determining that the WTRU is allowed to access the first neighbor cell. The WTRU may determine that the WTRU is allowed to access the first neighbor cell based on the first PCI and the PCIs to AIDs mapping.

  • Publication number: 20240072393
    Abstract: A battery cell includes: a shell, including a first wall; an electrode assembly, disposed inside the shell; and a terminal assembly, including an electrode terminal and an elastic member. The electrode terminal includes a fixed portion for electrical connection with the electrode assembly and a movable portion for electrical connection with a current collecting component. The fixed portion is fixedly disposed on the first wall. The movable portion is movably disposed on the first wall, and has a first position in contact with the fixed portion and a second position separated from the fixed portion. The elastic member is used for applying elastic force to the movable portion to maintain the movable portion in the first position. The movable portion is configured to move from the first position to the second position against the elastic force when internal pressure of the battery cell reaches a threshold.

  • Publication number: 20240057214
    Abstract: 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.

  • Patent number: 11855892
    Abstract: A system and apparatus for addressing the different types of mobility of a wireless transmit/receive unit (WTRU) in a network. A radio access network (RAN) may send a request for configuration information to a gateway device including a device ID of a WTRU, a service ID, and a RAN address. Once the RAN receives configuration information from the gateway device including a forwarding table, the RAN may be prepared to receive non-IP data from a WTRU including a routing tag. The routing tag may be based on the device ID of a WTRU and service ID. The RAN may transmit the non-IP data received from the WTRU to the gateway device over a routing path based on the routing tag and a forwarding table where the non-IP data is forwarded on to its detention, such as another WTRU or an Application Server.
