  • Patent number: 12219625
    Abstract: A method of connection establishment through a relay UE for a remote UE is proposed. The remote and relay UEs first perform discovery and establish a PC5 radio resource control (PC5-RRC) connection. Upon receiving a request from the remote UE, the relay UE and a serving gNB perform a relaying procedure for establishment of the remote UE's signalling radio bearer 1 (SRB1). The relay UE configures PC5 RLC channels for relaying of SRB1 towards the remote UE. The remote UE then enters an RRC_CONNECTED state. The remote UE and gNB establish security. The gNB configures additional data radio bearers (DRBs) for relaying. The relay UE configures PC5 RLC channels for relaying of the additional DRBs towards the remote UE. The DRBs can then be used for exchange of data between the remote UE and the gNB.

  • Patent number: 12096222
    Abstract: This application provides a fake network device identification method and a communications apparatus. An uplink message sent by a terminal device is forwarded to a first network device via a second network device. After receiving the uplink message, the first network device generates a downlink message for the uplink message, performs security processing on the downlink message based on first time information, and/or sends the downlink message to the second network device. The second network device sends, to the terminal device, the downlink message on which the security processing is performed. The terminal device performs security verification on the received downlink message, and/or identifies whether the second network device is a fake network device. This helps improve communication security.
