Abstract

A system and method for access control to a Femto cell network. The system prevents access for unauthorized user equipments (UE) to a Femto cell with a particular Location Area Code (LAC) by temporarily averting access to that particular FAP. If the Femto cell Access Point (FAP) gets a connection request from an unauthorized UE, the FAP fails the first authentication check for that particular UE. Upon authentication failure, the UE activate a first timer and checks if the FAP sends a second authentication request before expiry of the first timer. In an embodiment, FAP does not send second authentication request if the UE is found to be unauthorized. Then the UE activates a second timer and goes to idle state. Further, the UE will not scan for FAPs with that particular Location Area Code till expiry of the second timer.
