Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional call routing methods are used, then call routing is simple, but routing accuracy and efficiency deteriorate leading to errors and delays
Solution Approach 1:
The system performs preliminary analysis of call routing data, UE location information, and PSAP capacity metrics before actual call routing occurs. This proactive approach identifies potential routing issues and optimizes routing decisions in advance, improving accuracy without adding complexity to the real-time routing process
Solution Approach 2:
An intermediary call routing optimization system is introduced between the traditional routing method and the actual call connection. This intermediary layer analyzes multiple data sources including UE location, PSAP capacity, and historical routing data to make intelligent routing decisions, thereby improving accuracy while managing complexity through a dedicated intermediate component
2Reliability
If manual routing verification is performed, then routing errors are reduced, but response time increases
Solution Approach 1:
The system implements self-service automated verification mechanisms that continuously monitor and validate call routing decisions without requiring manual intervention. The automated system cross-checks routing accuracy, monitors PSAP capacity, and adjusts routing parameters in real-time, maintaining high reliability while eliminating time-consuming manual verification steps
Solution Approach 2:
A feedback mechanism is established where routing outcomes are continuously monitored and fed back into the routing decision system. This real-time feedback loop enables the system to learn from past routing decisions, automatically correct errors, and optimize future routing choices, thereby maintaining high reliability without manual intervention and minimizing delays
3Productivity
If more PSAPs are monitored for load balancing, then call distribution efficiency improves, but system complexity increases
Solution Approach 1:
The monitoring system is designed with multi-functionality to handle multiple PSAPs simultaneously using a unified monitoring framework. This universal system can scale to monitor any number of PSAPs without proportionally increasing complexity, as it uses standardized metrics and a single integrated platform to track load, capacity, and performance across all monitored PSAPs
Solution Approach 2:
The system dynamically adjusts monitoring parameters such as load thresholds, capacity metrics, and routing priorities based on current network conditions and PSAP performance. By changing these parameters adaptively rather than maintaining fixed complex configurations, the system achieves efficient call distribution across multiple PSAPs while managing complexity through flexible, condition-based parameter adjustment
