LRN-Based Subscriber Cutover Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing technologies for subscriber cutover in telecommunications networks face challenges due to time delays in updating number portability databases and the need for expensive hardware upgrades to implement special cutover triggers, which are undesirable.
Innovation Solution
Implementing a Location Routing Number (LRN) based query and response mechanism to effect subscriber cutover, where a routing node intercepts and modifies number portability response messages to include a cutover switch LRN, allowing the switching office to route calls to the new end office without requiring immediate database updates or hardware upgrades.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the number portability database is updated with the new end office LRN, then call routing to the cutover subscriber is enabled, but there is a time delay between subscriber cutover and database population
Solution Approach 1:
The patent applies preliminary action by proactively inserting the cutover end office LRN into the number portability database before the subscriber's calls need to be routed. The system detects the cutover event and preemptively updates the database with the new LRN, ensuring that when calls arrive, the routing information is already in place, thereby eliminating the time delay between cutover and database population.
Solution Approach 2:
The patent implements feedback mechanisms where the system monitors cutover events and uses this information to trigger database updates. The feedback loop ensures that the database is continuously synchronized with actual subscriber location changes, allowing real-time detection and response to cutover events, thus resolving the time delay issue.
2Adaptability or versatility
If special cutover triggers are provisioned in each switching office, then subscriber cutover processing is enabled, but expensive hardware and software upgrades are required
Solution Approach 1:
The patent applies universality by making the existing number portability database and processing functionality serve dual purposes: traditional LNP processing and cutover management. Instead of provisioning separate special triggers in each switching office, the system leverages the universal LNP infrastructure to handle cutover events, eliminating the need for expensive hardware and software upgrades while maintaining full cutover processing capability.
Solution Approach 2:
The patent implements self-service by enabling the existing LNP system to autonomously handle cutover processing without requiring additional specialized triggers or infrastructure. The system uses its own existing resources (database, processing logic) to manage cutover events, thereby avoiding the need for external hardware and software upgrades.
3Ease of manufacture
If the number portability database is used for cutover processing, then existing processing functionality is leveraged, but the database must be populated via NPAC and local LSMS which causes time delay
Solution Approach 1:
The patent applies preliminary action by proactively inserting the cutover end office LRN into the number portability database before the subscriber's calls need to be routed. The system detects the cutover event and preemptively updates the database with the new LRN, ensuring that when calls arrive, the routing information is already in place, thereby eliminating the time delay between cutover and database population.

AI summary
A method for using an LRN based query and response mechanism to effect subscriber cutover includes receiving an LRN based response message including a communications service subscriber identifier. The method further includes determining a cutover switch LRN associated with the communications service subscriber identifier. The method further includes inserting the cutover switch LRN associated with the communications service subscriber identifier into the LRN based response message and routing the LRN based response message.
