    Abstract: A user plane integrity protection method comprises sending user plane integrity protection information of a user equipment (UE) to a first network device, wherein the user plane integrity protection information indicates whether the UE supports a user plane integrity protection, and enabling, when the UE supports the user plane integrity protection and after receiving first information from the first network device, the user plane integrity protection according to a user plane integrity protection algorithm.

    Abstract: 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.

    Abstract: Embodiments of this application provide a data check method, a data check apparatus, and a storage medium. The data check method includes: obtaining a first counter value and a second counter value, where the first counter value is a value obtained by performing counting by UE during data transmission between the UE and a UPF entity, and the second counter value is a value obtained by performing counting by the UPF entity during the data transmission between the UE and the UPF entity; determining whether the first counter value matches the second counter value; and if the first counter value does not match the second counter value, sending a response message to a session management network element.
