Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in efficiently performing network slice specific cell selection, leading to issues such as loss of coverage and failure to initiate call setup.
Innovation Solution
The method involves a user equipment (UE) receiving information about network slice specific cell selection evaluation parameters, which include parameter values associated with the characteristics of the cell selection type to be performed. The UE then performs the cell selection based on these parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If network slice specific cell selection evaluation parameters are not used, then the cell selection process is simple, but coverage loss and call setup failures occur
Solution Approach 1:
The patent applies parameter changes by introducing network slice specific evaluation parameters (such as Qrxlevminoffset and Qqualminoffset) that modify the standard cell selection criteria. These parameters are adjusted based on the network slice type (e.g., eMBB, URLLC, mMTC) to optimize cell selection for different service requirements, thereby improving coverage reliability without requiring a complete redesign of the cell selection mechanism
Solution Approach 2:
The patent segments the cell selection process by introducing separate evaluation parameters for different network slices. Instead of using a single unified cell selection criterion, the system divides the selection process into slice-specific evaluations, allowing each network slice to have optimized parameters tailored to its specific requirements (e.g., low latency for URLLC, high throughput for eMBB)
2Adaptability or versatility
If different coverage deployments are not allowed for different network slices, then the network configuration is simple, but communication interruptions occur
Solution Approach 1:
The patent applies local quality by allowing different evaluation parameters to be configured for different network slices. Each network slice can have locally optimized parameters (such as different threshold offsets, measurement criteria, or reselection priorities) that are tailored to its specific quality requirements, enabling customized coverage deployments for different services while maintaining a unified network infrastructure
Solution Approach 2:
The patent introduces dynamics by enabling the network to dynamically assign and adjust slice-specific evaluation parameters based on service requirements, UE capabilities, and network conditions. The system can adaptively modify parameters such as cell reselection thresholds and measurement priorities for different network slices, allowing flexible response to changing communication demands without static rigid configuration
