Abstract
This application provides a network slice allocation method, device, and system, including a terminal device, a first core network device, a second core network device, and a third core network device. The terminal device encrypts NSSAI and an ID of the terminal device to obtain encrypted information, and sends a slice access request message to the first core network device. The first core network device sends the encrypted information to the second core network device. The second core network device decrypts the encrypted information to obtain the NSSAI and the ID of the terminal device, generates an authentication vector, and sends the NSSAI and the authentication vector to the first core network device.
