摘要

Example authentication methods, devices, and systems are provided, where those example can be used to verify validity of access location information of a next generation-residential gateway (NG-RG) in a fixed-mobile convergence architecture. One example method includes a network device receiving first link information that is used to represent an access location of a residential gateway, and the network device obtaining second link information of the residential gateway. When the first link information matches partial or all information of the second link information, or when the first link information matches partial or all information of one link information of the second link information, the network device verifies validity of the access location of the residential gateway.

說明書

The communications device 400 may be a general-purpose device or a special-purpose device. During specific implementation, the communications device 400 may be a desktop computer, a portable computer, a network server, a palmtop computer (PDA), a mobile phone, a tablet computer, a wireless terminal device, an embedded device, or a device with a structure similar to that in FIG. 4. A type of the communications device 400 is not limited in the embodiment of this application.

The following describes in detail an authentication method provided in the embodiment of this application with reference to FIG. 1 to FIG. 4.

It should be noted that in the following embodiments of this application, names of messages between network elements, names of parameters in messages, or the like are merely examples, and there may be other names during specific implementation. This is not specifically limited in the embodiment of this application.

First, an example in which the authentication system shown in FIG. 1 or FIG. 2 is applied to the fixed-mobile convergence network architecture shown in FIG. 3 and the network device is a UDM network element is used. FIG. 5A, FIG. 5B, and FIG. 5C show an authentication method according to an embodiment of this application. The authentication method includes the following steps.

S501: An NG-RG sends a registration request message to a W-5GAN device.

Correspondingly, the W-5GAN device receives the registration request message from the NG-RG.
