Cell Reselection Configuration Extraction for Terminal Power Saving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In current cell reselection processes, terminals need to read system information from both the serving cell and neighboring cells, which consumes computing resources and power, as they must obtain configuration information for potential cell reselection.
Innovation Solution
A method where a terminal receives system information from a serving cell, extracts configuration information related to cell reselection, and performs reselection based on this information and signal quality, without necessarily listening to system information from the neighboring cell, thereby reducing resource and power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the terminal reads system information from both serving cell and neighboring cells to obtain configuration information for cell reselection, then the cell reselection accuracy is improved, but the computing resource consumption and power consumption increase
Solution Approach 1:
The patent extracts only the necessary configuration information for cell reselection from the neighboring cell's system information and includes it in the serving cell's system information. This allows the terminal to obtain the required configuration data without reading the entire system information of neighboring cells, thereby reducing power consumption while maintaining cell reselection accuracy.
Solution Approach 2:
The access network device pre-processes and includes the configuration information of neighboring cells in the serving cell's system information before the terminal needs it. This preliminary action allows the terminal to directly use the pre-packaged configuration information without performing additional reading and processing operations on neighboring cell system information, reducing both power consumption and processing time.

3Loss of information
If the terminal listens to system information of neighboring cell to obtain configuration information, then the configuration information completeness is improved, but the time consumption increases
Solution Approach 1:
The patent merges the configuration information of neighboring cells with the serving cell's system information. The terminal can obtain both serving cell and neighboring cell configuration information from a single source (the serving cell's system information), eliminating the need to separately read and process neighboring cell system information, thus reducing time consumption while maintaining information completeness.
Solution Approach 2:
The access network device pre-processes and includes the configuration information of neighboring cells in the serving cell's system information before the terminal needs it. This preliminary action allows the terminal to directly use the pre-packaged configuration information without performing additional reading and processing operations on neighboring cell system information, reducing both power consumption and processing time.
