Abstract: A method for rebalancing SLF subscriber data includes, generating, by a provisioning gateway, a rebalancing report and transmitting the report to a provisioning system. The method further includes receiving, at the provisioning gateway and from the provisioning system, a request to initiate re-provisioning of subscriber data among 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. The method further includes, 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.

Abstract: A method for supporting a migration of user profile and policy information includes receiving a 5G user profile addition request message associated with a subscriber entity, sending a user profile query message to a 4G subscription profile repository (SPR), determining that 4G user profile and policy information corresponding to the subscriber entity exists in the 4G SPR, and receiving 4G user profile and policy information corresponding to the subscriber entity from the 4G SPR and subsequently sending a 5G user profile creation message containing the 4G user profile and policy information to a 5G unified data repository (UDR) in response to determining that the 4G user profile and policy information is stored in the 4G SPR.
