Abstract:
Provided are a network authentication method, a network device and a core network device. The method comprises: a first network device receiving an access request message sent by a terminal device, the access request message comprising an identity identifier of the terminal device; the first network device judging, according to the identity identifier of the terminal device, whether the terminal device is allowed to be authenticated; if the first network device does not allow the terminal device to be authenticated, then the first network device sending the identity identifier of the terminal device to a core network device, so that the core network device performs network authentication according to the identity identifier of the terminal device; if the first network device allows the terminal device to be authenticated, then the first network device sending an authentication request message to the terminal device, so that the terminal device authenticates the first network device according to the authentication request message; and receiving an authentication response message sent by the terminal device, and authenticating the terminal device according to the authentication response message. As such, the problem of how to carry out network authentication can be effectively solved.
