Abstract
The present invention relates generally to dividing a cellular mobile communications system into general geographic areas. The cellular system is logically divided into an access provider, having knowledge of and controlling access to the system over the air interface, and a core service provider having subscribers and providing services to those subscribers over the bearer services provided by the access provider. The core service provider chooses some general area within which a particular service is to be provided or within which access is to be restricted. This information is transmitted to the access provider who then maps this information onto the cellular system, thereby determining which cells within the network lie within the area designated by the core service provider.
