Abstract

The invention discloses a system and a method for preauthenticating a terminal switched among different management domains, which can reduce the switching time delay of the terminal switched among the different management domains during switching. The method comprises the following steps that: the terminal transmits a preauthentication request to a hometown authentication server after receiving a preauthentication initiating message sent by the original management domain or a destination management domain; the hometown authentication server and the terminal perform preauthentication interaction; and the hometown authentication server sends a preauthentication success message to the terminal and the destination management domain after the preauthentication succeeds. By the system and the method, after a user who is successfully preauthenticated switches the terminal, the authentication process of switching to the destination management domain is reduced, the time delay is reduced, and the service continuity is improved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a pre-authentication system and method for a terminal to switch between different management domains. Background technique [0002] In a mobile network, a terminal can switch between different access points. If two different access points belong to different management domains, a complete authentication process needs to be performed when the terminal switches between the original management domain and the target management domain. [0003] In the prior art, the complete authentication performed by the terminal switching between two management domains has at least the following technical defects: [0004] 1) The complete authentication process requires a longer delay than physical handover. [0005] 2) When the terminal performs handover in the roaming network, the time delay for the user to authenticate in the local domain is much greater than that when the user ...
