Title:
NETWORK SLICE ALLOCATION METHOD, DEVICE AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/004929
Kind Code:
A3
Abstract:
The present application provides a network slice allocation method, device and system. The system comprises a terminal device, a first core network device, a second core network device, and a third core network device. The terminal device encrypts a 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, so as to generate an authentication vector, and sends the NSSAI and the authentication vector to the first core network device. The first core network device determines the third core network device according to the NSSAI. If the first core network device is different from the third core network device, the first core network device sends the slice access request message, the NSSAI, and the authentication vector to the third core network device, such that the third core network device allocates a network slice for the terminal device, thereby reducing the security risks of a network communication system.
