System and method for fast network re-entry in a broadband wireless access communication system
First Claim
1. A method for fast network re-entry of a mobile station in a broadband wireless access communication system, the method comprising the steps of:
- transmitting a first message requesting fast network re-entry to a base station when the mobile station detects that it is necessary to perform network re-entry to the base station in an idle state in which the mobile station stores final session information of a previous active state;
receiving a second message approving the fast network re-entry from the base station; and
performing the fast network re-entry with the base station.

Abstract
A system and method for fast network re-entry in a broadband wireless access communication system. A mobile station transmits a first message requiring fast network re-entry to a base station and performs the fast network re-entry together with the base station when receiving a second message approving the fast network re-entry from the base station. The base station receives the first message, authenticates the first message using final session information of the mobile station that is previously stored in the base station, transmits the second message to the mobile station when succeeding in authentication of the first message, and performs the fast network re-entry together with the mobile station.

8. A method for fast network re-entry of a mobile station in a broadband wireless access communication system including the mobile station, a serving base station that provides service to the mobile station, a target base station, which is different from the serving base station, and an ASA (Authentication and Service Authorization) server connected to the target base station, the method comprising the steps of:
-
storing final session information by the mobile station when transitioning into an idle state;
transmitting the final session information to the target base station so that the target base station and the ASA server store the final session information, when the mobile station detects that handover from the serving base station to the target base station is necessary, after the mobile station stores the final session information;
transmitting a first message requiring fast network re-entry to the target base station;
receiving a second message approving the fast network re-entry from the target base station; and
performing the fast network re-entry with the target base station. - View Dependent Claims (9, 10, 11, 12, 13, 14)

-
transmitting final session information from the mobile station to the target base station so that the target base station and the ASA server store the final session information, when the mobile station detects that handover from the serving base station to the target base station is necessary, after the mobile station stores the final session information while transitioning into an idle state;
receiving the final session information in the target base station;
storing the final session information in the target base station;
transmitting a first message requiring the fast network re-entry to the target base station;
receiving the first message by the target base station;
authenticating the first message by the target base station using final session information of the mobile station stored in advance in the target base station;
transmitting a second message approving the fast network re-entry to the mobile station, after authenticating the first message; and
performing the fast network re-entry by the mobile station and the target base station. - View Dependent Claims (30, 31, 32, 33, 34, 35)
