Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the location area is made large to enable location of mobile terminal with certain probability of success, then the location success probability is improved, but the resource consumption of the wireless telecommunication network increases
Solution Approach 1:
The patent implements dynamic location area adjustment by continuously monitoring mobile terminal movement patterns and adapting the location area boundaries accordingly. The system transitions from static radio planning-based location areas to dynamic, movement-adaptive location areas that expand when terminals move frequently and contract when terminals remain stationary, thereby resolving the contradiction between location success probability and resource consumption
Solution Approach 2:
The system employs feedback mechanisms by collecting location update information from mobile terminals and using this data to adjust location area configurations. The network monitors terminal movements and feeds this information back to the location area management system, which then optimizes location area sizes based on actual usage patterns rather than theoretical radio planning, achieving better resource efficiency while maintaining location success rates
2Loss of energy
If the location area is reduced to save resources of the wireless telecommunication network, then the resource consumption is decreased, but the location success probability deteriorates
Solution Approach 1:
The system dynamically adjusts location area sizes based on real-time mobile terminal movement behavior. When terminals exhibit stationary patterns, the system reduces location area sizes to save resources. When movement patterns indicate frequent transitions, the system expands location areas to maintain location success probability, thus resolving the trade-off between resource consumption and location reliability
3Device complexity
If a fixed location area is determined according to radio planning techniques, then the network configuration is simplified, but the location area determination is not adapted to each mobile terminal
Solution Approach 1:
The patent applies local quality by customizing location areas for individual mobile terminals based on their specific movement patterns rather than using uniform location areas for all terminals. Each terminal receives a tailored location area configuration that matches its local movement characteristics, achieving high adaptability while maintaining manageable network complexity through automated pattern recognition
Solution Approach 2:
The system enables mobile terminals to effectively define their own location areas through their movement patterns. By monitoring terminal movements and automatically generating personalized location area configurations, the system eliminates the need for manual radio planning adjustments while achieving adaptive, terminal-specific location optimization
