Abstract: A route information update method includes: A second terminal generates route information of a first terminal, where a relay function of the second terminal provides a communication service for the first terminal and a first device based on the route information of the first terminal, and the first device includes a third terminal and/or a network device. The second terminal updates the route information of the first terminal to generate updated route information of the first terminal. The second terminal sends a second message to the first terminal, where the second message includes the updated route information of the first terminal. When the first device includes the third terminal, the second terminal sends the updated route information of the first terminal to the third terminal.

Abstract: Example authentication methods, devices, and systems are provided, where those example can be used to verify validity of access location information of a next generation-residential gateway (NG-RG) in a fixed-mobile convergence architecture. One example method includes a network device receiving first link information that is used to represent an access location of a residential gateway, and the network device obtaining second link information of the residential gateway. When the first link information matches partial or all information of the second link information, or when the first link information matches partial or all information of one link information of the second link information, the network device verifies validity of the access location of the residential gateway.

Abstract: A detection and communication system, a control apparatus, and a detection system are disclosed, and may be applied to fields such as augmented reality AR, virtual reality VR, or vehicle-road synergy. The detection and communication system includes: N radars, configured to: separately search for a target, and separately align with the target, where N is an integer greater than 1, K radars that are in the N radars and that align with the target are configured to communicate with the target, N-K radars other than the K radars are configured to track and point the target, and K is a positive integer less than N. The N radars separately align with the target, to help improve precision of alignment between the radar and the target. In addition, some of the N radars may communicate with the target.

Abstract: This application provides a key configuration method. A session management network element receives a request for end-to-end communication and obtains a security policy, where the security policy is determined based on at least one of: a user security requirement that is of the user equipment and that is preconfigured on a home subscriber server, a service security requirement from the user equipment, a security capability requirement supported by the user equipment, a security capability requirement from a carrier network, and a security requirement of a device on the other end of the end-to-end communication. The session management network element obtains a protection key used for protecting the end-to-end communication. The session management network element sends the security policy to the devices on two ends of the end-to-end communication.
