Methods, systems, and computer readable media for rebalancing subscriber location function (SLF) subscriber data

A non-transitory computer readable medium having stored thereon executable instructions that when executed by a processor of a computer control the computer to perform steps comprising:

• at a provisioning gateway, generating a rebalancing report and transmitting the rebalancing report to a provisioning system;
• receiving, at the provisioning gateway and from the provisioning system, a request to initiate re-provisioning of subscriber data among subscriber location function (SLF) instances, the request for re-provisioning identifying a first range of subscriber identifiers currently assigned to a first SLF instance to be re-assigned to a second SLF instance;
• and
• in response to the request to initiate the re-provisioning, signaling, by the provisioning gateway, transparently from the provisioning system, and with the first and second SLF instances to move subscriber database records having subscriber identifiers in the first range from a subscriber database maintained by the first SLF instance to a subscriber database maintained by the second SLF instance.
