Abstract

A common channel signaling system interconnects two home location registers. A data administrator responds to a network operator request by sending commands to a first (originating) home location register to have subscriber data extracted and formatted for communication over the common channel signaling system. Prior to communication, the first home location register verifies a common channel signaling system functionality level of a second (destination) home location register. If verified, the communication is sent, unformatted, and the included subscriber data stored. A data network and service management access layer further interconnect the two home location registers. The data administrator responds to a generic network operator migration request by generating home location register specific commands instructing the first home location register to extract subscriber data for transfer over the data network and through the service management access layer to the second home location register for storage. Transfer considerations are also evaluated to select either the common channel signaling system or data network for the migration.
