Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G networks, terminals often struggle with cell reselection due to a lack of network slice information, leading to suboptimal service quality and delayed or low-quality communication services.
Innovation Solution
A method and apparatus for cell reselection that involves receiving and utilizing network slice information in system messages, allowing terminals to perform informed cell reselection based on supported network slices, thereby ensuring access to high-quality communication services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If terminals perform cell reselection without network slice information, then cell reselection can be performed quickly and simply, but the accuracy of cell reselection deteriorates leading to suboptimal service quality
Solution Approach 1:
The base station performs preliminary action by including network slice information in system messages before the terminal needs to make cell reselection decisions. This allows the terminal to have advance knowledge of which neighbor cells support required network slices, enabling accurate cell reselection without complex real-time analysis.
Solution Approach 2:
Network slice information acts as an intermediary that bridges the terminal and neighbor cells. The base station transmits this information through system messages, allowing the terminal to indirectly understand which neighbor cells support its required network slices without direct interaction with those cells, thus improving reselection accuracy while maintaining process simplicity.
2Reliability
If terminals lack network slice information during cell reselection, then the cell reselection process remains simple, but communication service quality deteriorates
Solution Approach 1:
The base station provides network slice information in advance through system messages before the terminal performs cell reselection. This preliminary provision of information ensures that the terminal can make informed decisions about which neighbor cells to select, thereby maintaining high communication service quality without experiencing information loss during the reselection process.
3Productivity
If terminals perform cell reselection without network slice information, then cell reselection can be performed quickly, but service delay increases due to low-quality connections
Solution Approach 1:
By providing network slice information in advance through system messages, the terminal can quickly identify suitable neighbor cells during reselection without needing to perform complex real-time evaluations. This preliminary information provision maintains fast reselection speed while preventing service delays caused by connecting to inappropriate cells that don't support required network slices.
