Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If edge computing service is provided to mobile UE, then data transmission efficiency is improved, but service reliability deteriorates due to location changes
Solution Approach 1:
The system implements a feedback mechanism where the edge enabler server continuously monitors the location of mobile UEs and compares it with the location information stored in the database. When location changes are detected, the system automatically updates the database and notifies relevant application servers, ensuring service reliability is maintained through continuous feedback loops.
Solution Approach 2:
The edge enabler server acts as an intermediary between the mobile UEs, application servers, and location database. It manages location information centrally, receives location requests from application servers, and coordinates updates across the system, thereby maintaining service reliability while enabling efficient edge computing operations.
2Reliability
If location information is continuously monitored, then service reliability is improved, but energy consumption increases
Solution Approach 1:
Instead of continuous monitoring, the system uses periodic location updates triggered by specific events such as UE location changes or application server requests. The edge enabler server checks location information periodically or on-demand, reducing unnecessary energy consumption while maintaining adequate service reliability.
Solution Approach 2:
The system enables self-service through automated location update mechanisms where UEs report their own location changes to the edge enabler server, and the server automatically updates the database and notifies relevant parties without requiring continuous active monitoring, thereby reducing energy consumption.
3Measurement precision
If detailed location information is provided, then location precision is improved, but information privacy worsens
Solution Approach 1:
The system applies local quality by providing different levels of location precision to different application servers based on their specific needs. The edge enabler server can selectively disclose location information, sharing only the necessary precision level with each application server, thereby maintaining privacy while satisfying diverse application requirements.
Solution Approach 2:
The system changes the parameter of location precision dynamically based on application requirements and privacy policies. The edge enabler server can adjust the granularity of location information provided, switching between precise coordinates and broader geographic areas, thereby balancing location precision with information privacy protection.
4Adaptability or versatility
If multiple application servers are managed, then service versatility is improved, but system complexity increases
Solution Approach 1:
The edge enabler server implements universality by designing a standardized interface and common location management mechanism that serves multiple application servers with diverse requirements. This single multi-functional system handles location requests, updates, and notifications for various applications, reducing overall system complexity compared to having separate management systems for each server.
Solution Approach 2:
The system applies segmentation by separating location management functions into distinct modular components: the edge enabler server, location database, and notification mechanism. This modular architecture allows multiple application servers to be managed independently through standardized interfaces, reducing system complexity while maintaining versatility.
