Local Number Portability Database Disaster Recovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for redirecting telephone communications during disasters, such as floods, are time-consuming and inefficient, particularly when redirecting both direct dialed and toll-free numbers to alternative facilities.
Innovation Solution
A disaster recovery plan that involves changing the local number portability database to transfer communications from one switch to another, allowing for seamless redirection of calls by programming the second switch to terminate phone numbers from the first switch, thereby enabling quick recovery and service continuity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the local switch is disabled due to a disaster, then the call center facility at that location cannot serve customers, but redirecting direct dialed numbers to the alternative facility is time-consuming and complex
Solution Approach 1:
The patent pre-configures the local number portability database with routing information that automatically redirects calls to alternative facilities when a disaster occurs. This preliminary setup eliminates the need for manual reconfiguration during the emergency, enabling automatic and rapid service redirection while maintaining reliability.
Solution Approach 2:
The system uses the local number portability database to automatically handle number redirection without requiring manual intervention. The database self-updates routing information based on disaster conditions, allowing the system to redirect both direct dialed and toll-free numbers automatically, significantly reducing the time and complexity of service recovery.
2Reliability
If both direct dialed numbers and toll-free access numbers are redirected manually, then complete service redirection is achieved, but the process is time-consuming and cannot be completed quickly during a disaster
Solution Approach 1:
The local number portability database automatically handles the redirection of both direct dialed and toll-free numbers without requiring separate manual processes. The database self-updates routing information, enabling simultaneous redirection of all number types in a single automated operation, thereby achieving complete service redirection at high speed.
Solution Approach 2:
The patent uses a single automated mechanism that simultaneously redirects both direct dialed numbers and toll-free access numbers to the alternative facility. This universal approach consolidates multiple redirection tasks into one process, achieving complete service redirection efficiently without the time penalty of handling each number type separately.
3Adaptability or versatility
If the toll-free number translation is changed to redirect calls, then toll-free access is maintained, but direct dialed numbers require separate manual redirection which increases complexity and time
Solution Approach 1:
The local number portability database automatically manages routing for both toll-free and direct dialed numbers through a single self-updating mechanism. This eliminates the need for separate manual redirection processes, reducing operational complexity while maintaining the ability to redirect both number types effectively during disaster recovery.
Data Source
AI summary
A method and apparatus is disclosed that establishes a disaster recovery plan to recover from the occurrence of a predetermined event. The plan enables the transfer of communications for at least one phone number from one switch to another switch by changing the local number portability database and programming the second switch to terminate the phone numbers from the first switch.
