The second network device performs UAS authentication on the first terminal device based on the UAS identifier, and sends a UAS authentication result of the first terminal device to the first network device. By implementing embodiments of this application, a terminal device manufactured by an unmanned aerial system device vendor that has not signed with an operator of a mobile communications network can be prevented from using the mobile communications network.

Identity authentication method and communications apparatus

A terminal device verification method and an apparatus are provided. The method includes: a first network device receiving a first message from a first terminal device. Then, the first network device verifies a pairing relationship between the first terminal device and a second terminal device. After the verification on the pairing relationship between the first terminal device and the second terminal device succeeds, the first network device sends a second message to the first terminal device, where the second message include first indication information, and the first indication information is used to indicate a pairing result of the first terminal device and the second terminal device. The pairing relationship between the first terminal device and the second terminal device is verified, so that the first terminal device and the second terminal device can be securely paired, to improve use security of the first terminal device and the second terminal device.

Terminal device verification method and apparatus

A communication method and apparatus are provided. The method includes: Second user equipment sends a second message, first user equipment sends a first message to a network device in response to the second message, to request to perform identity verification on the second user equipment, and the network device verifies whether an identity of the second user equipment is valid, and sends, to the first user equipment, a verification result indicating whether the identity of the second user equipment is valid. Alternatively, the first user equipment sends a third message for request the second user equipment to reply with information used for remote identification, and the second user equipment replies with a fourth message, where the fourth message includes the information used for remote identification on the second user equipment, and the third message and the fourth message are encrypted by using corresponding keys.

Communication method, apparatus, and system for verifying identity of user equipment by network device

Embodiments provide a communication method and a related product. The method includes: After primary authentication between a core network and a user equipment succeeds, a network function entity in the core network assists a data network in performing secondary authentication between the data network and the user equipment if the secondary authentication further needs to be performed between the data network and the user equipment; the network function entity obtains an authentication result of the secondary authentication and a restriction condition of the secondary authentication from the data network; and the network function entity stores the authentication result and the restriction condition into the core network. The restriction condition may be introduced for the secondary authentication, to make it possible that the authentication result is properly restricted for use, and to lay a foundation for effective management of the authentication result of the secondary authentication.

Communication method and related device

A terminal device obtains first slice selection assistance information, where the first slice selection assistance information is obtained by encrypting second slice selection assistance information, and the second slice selection assistance information is selection assistance information of a slice to which the terminal device is allowed to access. The terminal device sends a registration request message to an access network device, where the registration request message includes the first slice selection assistance information.

Communications method and apparatus
