Claims17
An apparatus comprising:
- a storage medium to store one or more authentication key contexts for one or more authentication keys associated with authenticating one or more corresponding mobile subscriber stations to be serviced in a coverage area of an access network serviced by the apparatus, each mobile subscriber station to be serviced while the corresponding authentication key remains unexpired;
- and
- an authentication module coupled to the storage medium and configured to purge the authentication key context of a mobile subscriber station from the storage medium when handing off the mobile subscriber station to be serviced in another coverage area of the access network by another apparatus, even if the authentication key of the mobile service station has not expired.
A method comprising:
- handing off a mobile subscriber station from a first base station to a second base station of an access network;
- and
- purging an authentication key context stored in a storage medium of the first base station on or after said handing off, the authentication key context being associated with an authentication key for authenticating the mobile subscriber station for accessing service of the access network, and the purging is performed even if the authentication key has not expired.
A system comprising:
- one or more omnidirectional antennas;
- and
- a base station coupled to the one or more of the antennas, and configured to purge an authentication key context of a supplicant from a storage medium of the base station when the supplicant is handed off to another system to service, even if the authentication key has not expired.
