An authentication result update method and a communications apparatus, where the authentication result update method includes: determining that an authentication result of a terminal device in a first serving network needs to be updated; and sending a first service invocation request to an authentication server, where the first service invocation request is used to request to update the authentication result stored in a unified data management device, where visited network spoofing can be prevented after authentication is completed, and where network security can be improved.

Authentication result update method and communications apparatus

A communication method and a communications device are provided. The communication method may include a service communication proxy (SCP) that receives a service request from a service consumer, where the service request carries a token, and the token includes a network function (NF) set identifier of a service producer. The SCP sends the service request to a service producer selected from a NF set of the service producer.

Communication method and communications device

A user plane integrity protection method sending, by a user equipment (UE), user plane integrity protection information of the UE to a first base station, wherein the user plane integrity protection information indicates whether the UE supports a user plane integrity protection, and enabling the user plane integrity protection according to a user plane integrity protection algorithm when the UE supports the user plane integrity protection.

User plane integrity protection method and apparatus, and device

A terminal device location determining method and a device. A core network device obtains location information of a terminal device reported by the terminal device and location information reported by a first base station. The core network device determines whether the location information of the terminal device matches the location information reported by the first base station, and if the location information of the terminal device does not match the location information reported by the first base station, the core network device sends a reject message to the terminal device. By determining, through comparison, whether the location information of the terminal device reported by the terminal device matches the location information reported by the base station, it can be determined whether a location of the terminal device is incorrectly determined.
