Abstract
An HLR Interface Facility (HIF) is disclosed which is disposed between the HLR and the different customer service data bases. The HIF resolves the two problems associated with the single HLR solution. It provides controlled access to the HLR, preventing secondary service providers from accessing or modifying each other'"'"'s subscriber records.
The HIF also offers interworking facilities, allowing to independently modify the interface into the HLR, and the new interface point between different customer service data bases and the HIF. Therefore, if a new feature is introduced in the MSC and only some of the secondary service providers wish to make use of it, only the interfaces between their customer service data bases and the HIF need modification while the other resellers need not change their own interfaces to the HIF.
In addition, a means for interfacing the billing output of the MSC to the multiple billing centers is disclosed.
