Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If external servers are deployed to provide services to wireless users, then service functionality is improved, but latency increases and user experience deteriorates
Solution Approach 1:
The patent transforms the service delivery architecture from a centralized external server model to a distributed edge computing model. Service functions are migrated from remote external servers to optimization servers deployed at the network edge (co-located with base stations), fundamentally changing the spatial dimension of service delivery. This reduces packet transit delay by eliminating long-haul network traversal while maintaining full service functionality.
2Speed
If LTE networks are used to meet bandwidth demands, then data rates are improved, but inter-cell interference increases and system capacity is reduced
Solution Approach 1:
The patent introduces optimization servers as intermediary components between base stations and external networks. These servers aggregate traffic from multiple base stations, enabling coordinated resource allocation and interference management. The intermediary facilitates cooperative mechanisms that reduce inter-cell interference while maintaining high data rates through optimized resource utilization.
3Reliability
If backhaul facilities are deployed to connect base stations, then network connectivity is improved, but backhaul utilization becomes over-loaded and other services are affected
Solution Approach 1:
The patent segments the backhaul traffic by introducing optimization servers that locally aggregate and process sensor data before transmission over the backhaul network. This segmentation separates local sensor data processing from remote server communication, reducing backhaul utilization for sensor applications while maintaining full network connectivity. The segmentation enables parallel processing paths that prevent backhaul overload.
4Productivity
If sensor data is processed and distributed through external servers, then data processing capability is improved, but latency increases and real-time distribution is compromised
Solution Approach 1:
The patent implements preliminary action by deploying optimization servers that pre-process and buffer sensor data at the network edge before external server requests are made. This preliminary local processing reduces the time required for data distribution by having data ready in advance at strategically located servers, eliminating the need for long-haul data transmission when distribution is requested.
