Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a universal access network is used for all users, then the network architecture is simple and easy to implement, but the network cannot meet the diverse requirements of different user types and network utilization is suboptimal
Solution Approach 1:
The access network is segmented into multiple dedicated access networks, each optimized for specific user types (e.g., C-MTC and M-MTC). This segmentation allows each network to be tailored to specific requirements while maintaining overall system functionality through standardized interfaces and protocols.
Solution Approach 2:
The network architecture enables dynamic selection of access networks based on user type requirements. UEs can be directed to appropriate dedicated access networks according to their service needs, allowing the system to adapt flexibly to different traffic patterns and requirements without requiring complete redesign for each user type.
2Productivity
If dedicated access networks are implemented for different user types, then network utilization and performance are improved, but the network architecture becomes more complex
Solution Approach 1:
While implementing dedicated access networks for different user types, the patent maintains universal interfaces and protocols that allow a unified core network to manage multiple dedicated access networks. This multi-functionality approach enables specialized service optimization while avoiding proportional increases in overall system complexity.
3Loss of energy
If signaling procedure is simplified for M-MTC users, then the control plane load is reduced, but the transmission delay may increase for C-MTC users who require low latency
Solution Approach 1:
Different signaling procedures are applied to different user types based on their specific requirements. M-MTC users receive simplified signaling procedures optimized for small data transmissions and reduced control plane load, while C-MTC users receive enhanced signaling procedures optimized for low latency and reliable connectivity. This localized optimization ensures each user type receives appropriate treatment without compromising others.
