Abstract

A consistency verification tool performs a consistency check on subscriber data records stored in the cellular telephone system. One such consistency check analyzes subscriber data records in a home location register (HLR) and a billing system to determine the presence of duplicate records. Duplicate records can be stored in a duplicate record file for later analysis. During the duplicate record consistency analysis, the consistency verification tool creates a record list. The record list can be a linked list structure for storing main records and duplicate records in a manner that facilitates identifying families of duplicate records. The consistency verification tool can also perform inter-device consistency checks. For example, the subscriber data stored on the HLR can be compared to the subscriber data stored in the billing system to ensure that the two systems have consistent subscriber data.

Embodiment Construction

[0031]FIG. 1 is a schematic diagram illustrating a system for verifying subscriber data records in a cellular telephone system according to an embodiment of the present invention. A switch 102 is coupled to an IILR 103. HLR 103 comprises a disk 104. Disk 104 stores subscriber data. Preferably, disk 104 stores the subscriber data in a plurality of subscriber records. Disk 104 can be any data storage medium including, for example, disk, tape, CD-ROM or any other data storage medium. The subscriber records include data related to services available to each subscriber that is homed on switch 1 (12. Examples of services include local telephone service, long distance service, cellular service, paging service, and Internet service and other services, as well as features such as caller ID, call waiting, three-way calling, call forwarding and other features.
