Abstract: This application provides a network verification method and apparatus. The method may include: A slice statistics network element (30) receives a slice registration request message (410) from a mobility management network element (20), where the slice registration request message (410) includes an identifier of a terminal device (10) and an identifier of a network slice. In response to the slice registration request message (410), the slice statistics network element (30) determines whether the terminal device (10) occupies a resource of the network slice. The slice statistics network element (30) determines, based on a determining result, whether to count the terminal device (10) into statistics about a terminal accessing the network slice.

Abstract: This application provides a secure communication method and apparatus. The secure communication method includes: A session management function network element receives first security capability indication information from a terminal device, where the first security capability indication information indicates that the terminal device supports to establish a secure connection between the terminal device and a server. The session management function network element determines, based on the first security capability indication information, a first server that supports to establish the secure connection. The session management function network element sends information about the first server to the terminal device to establish the secure connection. According to the method, a server that matches a security capability of the terminal device can be selected, to ensure security protection for communication between the terminal device and the server, avoid information leakage or tampering, and help improve information exchange transmission efficiency.
