Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If edge computing technologies are deployed to provide low latency services, then service quality and responsiveness are improved, but destination IP addresses change frequently causing service disruption
Solution Approach 1:
The base station continuously monitors destination IP addresses associated with data services and receives notifications about IP changes from the control plane. This feedback mechanism enables the system to detect IP changes in real-time and trigger appropriate responses to maintain service continuity.
Solution Approach 2:
When an IP change is detected, the base station proactively transfers updated address information to the UE before service disruption occurs. This preliminary action ensures that the UE can immediately update its routing information and maintain continuous data service without interruption.
2Adaptability or versatility
If destination IP addresses are frequently updated to support server mobility, then adaptability is improved, but service quality deteriorates due to lack of real-time update mechanisms
Solution Approach 1:
The system implements a feedback loop where the base station receives notifications about IP changes from the control plane and monitors destination IPs associated with active data services. This ensures real-time awareness of server mobility events.
Solution Approach 2:
The base station acts as an intermediary between the control plane and the UE. It receives IP change notifications from the control plane, processes this information, and transfers updated address information to the UE, ensuring seamless service continuation despite server mobility.
3Device complexity
If address information is not promptly transferred to UE, then network complexity is reduced, but service continuity is broken when server addresses change
Solution Approach 1:
The base station implements monitoring of destination IP addresses and receives notifications from the control plane about IP changes. This feedback mechanism ensures that the base station is immediately aware of address changes and can trigger prompt transfer of updated information to maintain service continuity.
