Abstract
A screening list for a specific location within a mobile telecommunications system is assigned to a mobile subscriber. If the mobile subscriber is served by a Mobile Switching Center of that location, all originating and terminating calls are screened against the allowed directory numbers that have been stored in the screening list. If there is a match, telecommunications service is selectively provided. Otherwise, access is denied. A single mobile station can have separate screening lists for different locations within a mobile telecommunications system. Accordingly, a different screening list can be assigned to a Local Access and Transport Area, Network Area, Location Area and Cell Area within a mobile telecommunications system.
