Abstract:
A method and apparatus for authenticating a mobile terminal are provided. A list of potential Network Access Servers (NASs) corresponding to a NAS are maintained in a backend authentication server, authorization information corresponding to each of the potential NASs is transmitted, from the backend authentication server to each of the potential NASs, when the mobile terminal is authenticated via the NAS. The mobile terminal detects whether a new NAS is pre-authenticated, when the mobile terminal moves to a domain of the new NAS, the new NAS detects whether the mobile terminal is pre-authenticated, and the new NAS authenticates the mobile terminal via a Pre-Shared Key (PSK) method, when the mobile terminal and the new NAS are pre-authenticated.
