Patent ID: 7925259

Claim:
An access control method in a wireless communication network, wherein when a User Equipment (UE) is denied access to the network through a first access point, the UE stores on a list of forbidden LAIs in the UE, a location area identifier (LAI) utilized at the first access point, said method comprising the steps of: storing in an access point database in the network, by a radio network controller, the LAI stored by the UE on the list of forbidden LAIs; determining by the radio network controller whether the LAI stored by the UE on the list of forbidden LAIs is utilized at any other access point where the UE is allowed access, wherein the determining step includes querying the access point database by the radio network controller to extract a list of all of the allowed access points for the UE that are currently configured with the LAI stored by the UE; and when the LAI stored by the UE is utilized at another access point where the UE is allowed access, dynamically changing by the radio network controller, the LAI at the other access point to a second LAI that is not on the UE's list of forbidden LAIs, thereby enabling the UE to access the wireless communication network through the other access point.
