  • Patent number: 12212957
    Abstract: A method for UE-to-UE (U2U) relay discovery security is disclosed. The method may comprise provisioning an end-UE with security material for a direct discovery set and a U2U discovery message and provisioning a U2U relay with security material for the U2U discovery message. The security material for the direct discovery set may comprise at least one of: A ProSe restricted code, associated key material, or an indicator associated with a relay service code (RSC) that indicates whether the RSC supports per ProSe direct discovery set protection. The method may comprise sending, by the end-UE to the U2U relay, a direct connection request (DCR) message. The DCR message may comprise at least one of: an RSC, and end-UE User info identification (ID), or a ProSe restricted code. The method may comprise sending, by the end-UE, an indication for direct discovery set protection.

  • Publication number: 20250030661
    Abstract: A relay node may detect conflicts regarding media access control (MAC) addresses. A source node may send a request to the relay node. The request may be a request to establish communications with a target node. The source may send, to the relay node, an indication of the MAC address of the source node. The source node may receive a reject message from the relay node. The reject message may comprise an indication of a conflict associated with the MAC address of the source node.

  • Publication number: 20240414020
    Abstract: In some cases, various advanced end-user devices, such as wireless transmit receive units (WTRUs), may be used for consuming content (e.g., watching/listening to pre-recorded content, interacting with content or others, watching/listening to live content, data, traffic, etc.). Accordingly, in order to satisfy these new use cases, there may be a single PDU session management procedure(s) that distributes a single PDU session among multiple devices over networks. In some cases, there may be the distribution of functions belonging to a single terminal over multiple terminals thereby improving efficiency of execution and improved user experience.

  • Publication number: 20240214458
    Abstract: The disclosure pertains to methods and apparatus for establishing and maintaining a single PDU session with multiple terminal devices, such as for transferring a terminal function between two WTRUs or distributing the performance of a terminal function amongst a plurality of WTRUs. Additionally, methods and apparatus for SLA mapping for terminal function distribution are provided. SLAs for a single PDU session may be mapped among multiple distributed WTRUs based on the function demands for network slice selection. A set of devices running functions of the same PDU session may be selected and registered to the suitable slices based on their required SLAs. A network assisted function distribution slice selection function may serve over multiple slices in the 5G Core for an ongoing single PDU session among the chosen set of WTRUs.

  • Publication number: 20240155722
    Abstract: A first policy control function (PCF) in a first network node may receive an indication from a session management function (SMF) that a protocol data unit (PDU) session is an alternative PDU session, and an indication of whether the PDU session is in a drop state. The first PCF may send a message with an indication to a second PCF in a second network node to indicate that the network node is serving a PDU session that is an alternative PDU session. In an example, the message with an indication to the second PCF may also identify the PDU session. The first PCF may receive a message from the second PCF with an indication that a second PDU session has experienced a fault or degraded performance. Further, the first PCF may send a message to the SMF to change the PDU session to a no-drop state.

  • Publication number: 20240114465
    Abstract: A wireless transmit/receive unit (WTRU) may receive a power reporting policy from a network node. The power reporting policy may include one or more triggers associated with sending a power status report. The WTRU may determine that a trigger of the one or more triggers associated with sending the power status report has been satisfied. The WTRU may send the power status report to the network node in accordance with the power reporting policy. The power status report may include power status information associated with the WTRU and/or an indication that indicates the determined trigger to send the power status report.
