Wireless Network Slice Switching for Performance Degradation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication networks face inefficiencies in serving network slices to user devices and fail to effectively respond to network slice overloads.
Innovation Solution
Implementing a system that determines a first and second network slice for a user application, monitors performance, and switches user data exchange from the first slice to the second slice when performance thresholds are met, ensuring continuous service.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single network slice is used to serve user applications, then the network structure is simple, but the network cannot efficiently respond to performance degradation or overload conditions
Solution Approach 1:
The network is segmented into multiple network slices (first network slice and second network slice) that can independently serve user applications. Each slice operates as a separate service path, allowing the system to switch between slices based on performance conditions without affecting the overall network structure.
Solution Approach 2:
The system monitors performance parameters (such as service quality metrics) of the first network slice and dynamically changes the operational state by switching from the first slice to the second slice when performance degradation is detected, thereby adapting to changing network conditions.
2Reliability
If network slice performance is continuously monitored and switching is implemented, then service reliability is improved, but the system complexity increases
Solution Approach 1:
The system implements a feedback mechanism where the actual performance of the first network slice is continuously monitored and compared against expected performance levels. When performance degradation is detected through this feedback loop, the system automatically triggers a switch to the second network slice.
Solution Approach 2:
The second network slice is prepared in advance as a backup service path. When performance issues are detected in the first slice, the switch to the pre-prepared second slice occurs rapidly, minimizing service interruption without requiring complex real-time reconfiguration.
3Adaptability or versatility
If multiple network slices are implemented with performance monitoring, then the network can adapt to performance issues, but the operational complexity increases
Solution Approach 1:
The network system performs self-service through automated performance monitoring and slice switching. The system independently detects performance degradation in the first network slice and automatically switches to the second slice without requiring manual intervention, thereby maintaining ease of operation while achieving adaptability.

AI summary
A wireless communication system determines a first network slice and a second network slice to serve a user application. The wireless communication system identifies a performance level for the first network slice to serve the user application. The wireless communication system exchanges first user data using the first network slice to serve the user application. The wireless communication system determines actual performance of the first network slice to serve the user application. The wireless communication system compares the actual performance of the first network slice to the performance level for the first network slice, and in response, stops the exchange of the first user data to serve the user application using the first network slice and starts an exchange of second user data to serve the user application using the second network slice.
