Solution Overview

Problem

The increasing volatility in demand for phone numbers and short codes as telephony endpoints, coupled with the lack of a central registrar and slow transfer processes between carriers, creates a need for an efficient system to manage telephony endpoint inventory in real-time.

Innovation Solution

A system comprising a telephony endpoint management service that interfaces between communication platforms and a repository, using an API to track and monitor inventory across various dimensions, and a distributed set of endpoint management service instances for scalability, enabling the tracking, analysis, and management of telephony endpoint inventory, including classification, quality evaluation, and transfer processes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If phone numbers are held for long time to ensure availability, then inventory stability is improved, but real-time demand responsiveness deteriorates

Engineering Contradiction:
Improveinventory stabilityVSAvoidreal-time demand responsiveness
Core Design Contradiction:
Stability of the object's compositionVSSpeed

Solution Approach 1:

The system dynamically adjusts phone number retention policies based on real-time demand signals. Instead of static long-term holding, the system monitors usage patterns and demand fluctuations, automatically releasing numbers that are not actively used and prioritizing retention of numbers with high demand, thereby achieving both inventory stability and real-time responsiveness

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system implements continuous feedback loops that monitor phone number usage, demand signals, and inventory status. This feedback mechanism enables the system to learn from past patterns and adjust retention decisions in real-time, balancing the need for stable inventory with the requirement to respond quickly to changing demand

Inventive Principle:
Principle #23Feedback

2Productivity

If centralized registrar is implemented to improve management efficiency, then inventory control is improved, but system complexity and transfer time between carriers deteriorates

Engineering Contradiction:
Improvemanagement efficiencyVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent introduces a centralized registrar as an intermediary layer between carriers and end users. This registrar manages phone number assignments, portability, and inventory coordination without requiring direct complex interactions between multiple carriers, thereby improving management efficiency while containing system complexity through standardized interfaces

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The centralized registrar is designed as a universal system that handles multiple functions including number assignment, portability management, inventory tracking, and carrier coordination through standardized protocols. This multi-functional approach improves overall management efficiency without proportionally increasing complexity, as a single system performs diverse registration tasks

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Speed

If phone numbers are transferred quickly between carriers to meet real-time demand, then demand responsiveness is improved, but transfer reliability and quality assurance deteriorates

Engineering Contradiction:
Improvetransfer speedVSAvoidtransfer reliability
Core Design Contradiction:
SpeedVSReliability

Solution Approach 1:

The system performs preliminary quality checks, validation, and provisioning setup before completing the actual phone number transfer. By pre-verifying carrier compatibility, number status, and routing configurations in advance, the system enables faster transfers while maintaining reliability through upfront quality assurance rather than post-transfer verification

Inventive Principle:
Principle #10Preliminary action

AI summary

A system and method for managing an endpoint repository of a communication platform that includes managing a set of telephone endpoints that can be in an allocated state or an unallocated state; classifying endpoints of the set of telephone endpoints with a set of classifiers; evaluating endpoint inventory across a set of endpoint classification groupings and detecting at least one classification grouping that, based in part on the allocated and unallocated state of corresponding endpoints, satisfies an inventory update condition; generating an endpoint transfer request that specifies the endpoint classifiers of the classification grouping; and selectively adding endpoints from the inventory source to the endpoint repository.
