Wireless Cell Selection by Resource Configuration Checks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cell selection in wireless communication systems often prioritizes signal quality without considering the configuration of the cell's ability to support specific wireless resources required by the device, leading to suboptimal service provision.
Innovation Solution
Wireless devices select cells based on their configuration to support necessary wireless resources, such as network slices, by evaluating frequency ranges and communication links before selection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If cell selection is based only on received signal quality, then the selection process is simple and fast, but the selected cell may not meet the device's specific wireless resource requirements
Solution Approach 1:
The patent applies preliminary action by evaluating cell configuration parameters (frequency range, network slice support, communication link configuration) before the actual cell selection is made. This allows the wireless device to pre-determine whether a cell can meet its specific service requirements before committing to selection, thus avoiding selecting cells that cannot fulfill required services while maintaining an efficient selection process
2Reliability
If cell selection considers both signal quality and configuration capability, then service requirement fulfillment improves, but the selection process complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the cell evaluation process into distinct components: signal quality assessment and configuration capability assessment. The configuration capability is further segmented into specific checkable parameters such as frequency range support, network slice availability, and communication link configuration. This structured segmentation allows the device to systematically evaluate multiple factors without creating an unmanageably complex selection process
3Reliability
If the wireless device evaluates multiple cell configurations before selection, then the suitability of selected cell improves, but the time required for cell selection increases
Solution Approach 1:
The patent applies partial action by evaluating only the specific configuration parameters that are relevant to the device's current service requirements. Rather than comprehensively analyzing every possible cell parameter, the device focuses on checking key configuration aspects (frequency range, network slice, communication link) that directly impact service suitability, thereby achieving adequate evaluation without excessive time consumption
