Solution Overview

Problem

In call centers, customer requirements for quality of service (QoS) are often not matched with agent capabilities, leading to suboptimal communication due to factors like bandwidth and packet loss, affecting customer satisfaction, especially for video and audio transmissions.

Innovation Solution

A method and system for call routing that involves a routing server receiving customer media information, calculating customer requirement QoS, and matching it with an agent or IVR that can provide the necessary QoS by querying a database for quality of service data, ensuring that the service capability of the agent matches the network quality requirement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If calls are routed without considering QoS requirements, then call distribution speed is improved, but communication quality deteriorates due to bandwidth and packet loss issues

Engineering Contradiction:
Improvecall distribution speedVSAvoidcommunication quality
Core Design Contradiction:
SpeedVSReliability

Solution Approach 1:

The system performs preliminary QoS assessment by collecting agent network quality data beforehand and storing it in a database. When a call arrives, the routing server quickly queries pre-stored QoS data to match customer requirements with suitable agents, avoiding real-time QoS measurement delays while ensuring communication quality.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The routing server acts as an intermediary between the CTI system and agents, introducing a QoS matching layer that queries agent capabilities and customer requirements, then routes calls accordingly. This intermediary layer ensures both fast routing and quality matching without requiring direct real-time communication between CTI and agents.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If QoS matching is performed for every call, then communication quality is improved, but system complexity increases

Engineering Contradiction:
ImproveQoS matching accuracyVSAvoidrouting system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

Agent QoS capabilities are assessed and stored in advance in a database, eliminating the need for complex real-time QoS measurement and comparison systems. The routing server simply queries pre-stored data, significantly reducing system complexity while maintaining accurate QoS matching.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

Agents periodically self-report their network QoS status to the routing server, which automatically updates the database. This self-service mechanism eliminates the need for complex monitoring infrastructure, reducing system complexity while ensuring accurate QoS data for matching.

Inventive Principle:
Principle #25Self-service

3Adaptability or versatility

If remote agents access the network, then agent versatility is improved, but QoS reliability deteriorates due to access network limitations

Engineering Contradiction:
Improveagent remote access capabilityVSAvoidnetwork QoS stability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The system recognizes that different agents have different local network qualities (home broadband, mobile, corporate network). Instead of assuming uniform QoS, the patent collects and stores each agent's specific network characteristics, then matches customers with agents whose local network quality suits their communication requirements.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

Remote agents' network QoS characteristics are assessed and registered in advance with the routing server. This preliminary registration enables the system to account for remote access limitations when routing decisions are made, maintaining reliability despite agent versatility.

Inventive Principle:
Principle #10Preliminary action
