Methods, systems, and computer readable media for providing scalable number portability (NP) home location register (HLR)
First Claim
1. A system for providing a number portability (NP) home location register (HLR), the system comprising:
- an NP front end node for receiving requests for routing information for ported-in and non-ported foreign mobile subscribers, for making portability determinations in response to the requests, for processing or routing the requests based on the portability determinations, and for receiving and responding to provide roaming number requests for ported-out mobile subscribers, wherein the NP front end node receives the provide roaming number requests for the ported-out mobile subscribers from donor HLRs and responds to the donor HLRs with routing numbers corresponding to networks to which the ported-out mobile subscribers have been ported; and
at least one HLR back end node for performing HLR functions for ported-in foreign mobile subscribers including receiving, from the NP front end node, the requests for routing information for the ported-in foreign mobile subscribers and for responding to the requests with the routing information for the ported-in foreign mobile subscribers.

Abstract
The subject matter described herein includes methods, systems, and computer readable media for providing NP-HLR functionality. According to one aspect, the subject matter described herein includes a system for providing scalable NP-HLR. The system includes an NP front end node for receiving requests for routing information for ported-in and non-ported foreign mobile subscribers, for making portability determinations in response to the requests, for processing or routing the requests based on the portability determinations, and for receiving and responding to provide roaming number requests for ported-out mobile subscribers. The system further includes at least one HLR back end node for performing HLR functions for ported-in foreign mobile subscribers including receiving, from the NP front end node, the requests for routing information for the ported-in foreign mobile subscribers and for responding to the requests with the routing information for the ported-in foreign mobile subscribers.
