Abstract
A system, method, and arrangement for controlling access to a wireless communication network. When a User Equipment (UE) is denied access to the network through a first access point, the UE stores the Location Area Identity (LAI) utilized at the first access point on a list of forbidden LAIs in the UE. If the LAI stored by the UE is utilized at another access point where the UE is allowed access, the LAI at the other access point is dynamically changed to a second LAI that is not on the UE's list of forbidden LAIs. An access point database stores a table defining which UEs are allowed to utilize each access point. The database also stores a list of rejected LAIs for each UE. A radio network controller accesses the database to determine an allowed LAI, and changes the LAI at the other access points where the UE is allowed access.
