Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radio communication systems lack effective methods to predict and maintain quality of service (QoS) in industrial campus networks, leading to potential degradation and inefficiencies in network and application coordination.
Innovation Solution
A method and apparatus that utilize application-specific and radio access network information to predict future QoS, enabling proactive coordination and reaction to maintain QoS levels by exchanging coordination indicators between applications and networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If QoS prediction is implemented using existing radio communication methods, then future QoS can be estimated, but the prediction accuracy is insufficient due to lack of application-specific information
Solution Approach 1:
The patent implements a feedback mechanism where the predicted QoS is transmitted back to both the network side and application side. This feedback loop enables both parties to react proactively to maintain QoS levels, resolving the contradiction by utilizing available application-specific information effectively through the feedback channel.
Solution Approach 2:
The patent performs QoS prediction in advance before actual QoS degradation occurs. By determining the predicted QoS based on current operational parameters and transmitting this prediction proactively, the system enables preliminary reactions from both network and application sides to prevent QoS degradation, thereby improving prediction utility without requiring additional information.
2Reliability
If communication exchange between application and network sides is extended for coordination, then QoS can be maintained, but system complexity increases
Solution Approach 1:
The patent extends the communication exchange to serve multiple functions: transmitting QoS predictions, enabling coordinated reactions, and maintaining QoS guarantees. This multi-functional communication approach resolves the contradiction by making the extended communication exchange worthwhile through its diverse benefits, justifying the increased complexity.
Solution Approach 2:
The predicted QoS acts as an intermediary information element that mediates between the application side and network side. This intermediary enables coordinated reactions without requiring direct complex interaction between the two sides, as the prediction serves as a common reference point for both parties to independently determine their reactions.
3Reliability
If proactive reactions are implemented based on QoS prediction, then QoS degradation can be prevented, but response time requirements increase
Solution Approach 1:
The patent determines and transmits the predicted QoS in advance before actual QoS degradation occurs. This preliminary action enables both network and application sides to prepare and execute their reactions proactively, preventing QoS degradation before it happens. By acting in advance rather than reacting to degradation after it occurs, the system maintains reliability while managing time requirements through proactive timing.
