Solution Overview

Problem

Existing call routing systems in telecommunications often result in call blocking due to maximizing profitability by focusing on the most profitable routes, which can lead to caller dissatisfaction and operational losses, while neglecting routes with lower profit margins that may still be cost-effective but plagued by quality issues.

Innovation Solution

The implementation of an enhanced route table generator and server that blends quality considerations into the route selection process, using metrics like answer-seizure ratio and answered-call duration to optimize route choices and call allocations, ensuring more calls are routed successfully while maintaining profitability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If call routing focuses on maximizing profitability by selecting only the most profitable routes, then profitability is improved, but call routing success rate deteriorates due to call blocking

Engineering Contradiction:
ImproveprofitabilityVSAvoidcall routing success rate
Core Design Contradiction:
Loss of energyVSReliability

Solution Approach 1:

The patent applies local quality by differentiating route selection based on quality metrics. Instead of treating all routes uniformly, the system evaluates each route's answer-seizure ratio and answered-call duration locally, allowing calls to be routed through lower-profitability routes when those routes meet quality thresholds, thereby improving overall call success rates while maintaining profitability optimization.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The system dynamically adjusts route selection by incorporating real-time quality metrics (answer-seizure ratio and answered-call duration) into the routing decision process. The route table generator dynamically evaluates multiple routes and selects appropriate routes based on current quality conditions, allowing the system to adapt between profitability maximization and call success rate improvement depending on route performance.

Inventive Principle:
Principle #15Dynamics

2Reliability

If multiple routes with lower profit margins are included to reduce call blocking, then call routing success rate is improved, but profitability deteriorates

Engineering Contradiction:
Improvecall routing success rateVSAvoidprofitability
Core Design Contradiction:
ReliabilityVSLoss of energy

Solution Approach 1:

The patent changes the parameters of route evaluation by introducing quality metrics (answer-seizure ratio threshold and answered-call duration threshold) as additional constraints. The route table generator modifies its selection criteria to include these quality parameters, allowing it to selectively include lower-profitability routes only when they meet the quality thresholds, thus balancing call success rate improvement with profitability maintenance.

Inventive Principle:
Principle #35Parameter changes

3Reliability

If quality metrics are incorporated into route selection, then call routing quality is improved, but system complexity increases

Engineering Contradiction:
Improvecall routing qualityVSAvoidroute table generator complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system performs preliminary action by pre-calculating and storing quality metrics (answer-seizure ratio and answered-call duration) for each route in advance. The route table generator uses these pre-computed metrics to quickly evaluate routes without performing complex real-time calculations, thereby improving call routing quality while minimizing the increase in system complexity.

Inventive Principle:
Principle #10Preliminary action

AI summary

A system and method blend particular quality considerations into the process of expanding the route choices in a route table, such that more calls can be successfully routed while maximizing certain objectives. The quality considerations drive how additional routes are chosen for the route table and how call volumes are allocated to the chosen routes so that overall profitability can be maximized within the governing constraints of quality targets, route quality, predicted traffic, and route capacity.
