Solution Overview

Problem

Current Average Handling Time (AHT) models in contact centers penalize agents for necessary periods of silence during calls, such as when customers are asked to perform actions that require putting the phone down, failing to account for calls with inherent non-communication periods.

Innovation Solution

A system that detects events in communication sessions, analyzes periods of non-communication, and flags them if they exceed a defined threshold, allowing for context-based evaluation of contact center agent performance, using a contact center comprising an event detector, communications analyzer, templates, and previous call history to differentiate between necessary and problematic silences.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If current AHT models are used to measure silence in contact center calls, then Average Handling Time can be managed and agent performance can be monitored, but agents are unfairly penalized for necessary periods of non-communication such as when customers need to perform actions like resetting a modem

Engineering Contradiction:
Improvesilence measurement accuracyVSAvoidagent performance evaluation fairness
Core Design Contradiction:
Measurement precisionVSReliability

Solution Approach 1:

The patent applies local quality by creating different silence threshold criteria for different call contexts. Instead of using a uniform silence measurement standard, the system establishes context-specific thresholds that account for the nature of the call, the agent's actions, and expected customer behaviors. This allows necessary silences (like when customers perform modem resets) to be distinguished from problematic silences, thereby improving measurement precision without compromising evaluation fairness.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The system performs preliminary action by proactively identifying and flagging necessary periods of non-communication before they are penalized in performance evaluations. The patent implements this by monitoring calls in real-time, detecting when agents prompt customers to perform actions that require phone placement, and pre-marking these silence periods as acceptable. This preliminary identification prevents unfair penalties from being applied to necessary silences.

Inventive Principle:
Principle #10Preliminary action

2Ease of manufacture

If all periods of silence are treated equally in AHT calculations, then the measurement process is simple and consistent, but it fails to account for calls with inherent non-communication periods that are necessary for service delivery

Engineering Contradiction:
Improvemeasurement system simplicityVSAvoidcontext-based evaluation capability
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The patent applies dynamics by making the silence measurement system adaptive rather than static. The system dynamically adjusts silence thresholds and evaluation criteria based on call context, agent actions, and customer behavior patterns. This allows the measurement system to remain relatively simple in structure while gaining the versatility to differentiate between necessary and unnecessary silences through context-aware dynamic threshold adjustment.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system implements feedback by using detected call patterns and outcomes to continuously refine silence measurement criteria. The patent incorporates feedback loops where flagged silence periods are analyzed, and the system learns from these patterns to improve future silence detection accuracy. This feedback mechanism enables the system to become more adaptable to different call types and scenarios while maintaining operational simplicity.

Inventive Principle:
Principle #23Feedback

AI summary

An event associated with a communication session between a first party and a second party is detected. The event is related to the communication session. For example, the event may be a phrase spoken in the communication session or a presentation of a call progression screen to a contact center agent. At this point, the communication session is analyzed for a period of non-communication that meets a defined threshold during a monitoring period associated with the event. If a period of non-communication is detected that is longer than the threshold during the monitoring period, the period of non-communication is flagged. The flagged period of non-communication can then be used to evaluate how a contact center agent is performing.
