Historical QoE Cell Selection for Reliable Terminal Network Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Network access experiences, such as network stalling or failure, occur frequently in terminal devices due to high demand during peak hours, affecting user experience.
Innovation Solution
A cell selection method for terminal devices that utilizes historical quality of experience (QoE) to enhance or suppress measurement results, allowing the device to select cells with better network performance, thereby avoiding poor network access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If terminal devices select cells based on direct measurement results (RSRP/RSRQ), then the selection process is simple and fast, but the terminal device may access cells with poor network performance causing network stalling or failure
Solution Approach 1:
The terminal device performs preliminary actions by collecting and storing historical QoE data for cells before actual cell selection. This advance preparation enables the device to use historical performance information to predict future network quality, thereby avoiding cells that are likely to cause network stalling or failure while maintaining a relatively simple selection process.
2Ease of operation
If terminal devices use historical QoE data to select cells, then network access experience is improved by avoiding poor network cells, but the device complexity increases due to additional data collection and processing requirements
Solution Approach 1:
The terminal device implements feedback mechanisms by continuously collecting QoE data from actual network usage, storing it in a database, and using this feedback information to guide future cell selection decisions. This closed-loop approach improves network access experience by learning from past performance while managing complexity through systematic organization of feedback data.
Solution Approach 2:
The device performs preliminary data collection and storage of historical QoE information before making cell selection decisions. This advance preparation allows the terminal to leverage past performance data to predict future network quality, improving user experience while organizing the complexity into a structured preliminary processing stage.
3Measurement precision
If the terminal device collects and stores historical QoE data for all cells, then the accuracy of cell selection is improved, but the data storage requirements and processing time increase
Solution Approach 1:
The terminal device applies local quality by collecting and storing historical QoE data selectively for cells that are relevant to the current situation, such as neighboring cells or cells in the current location area. This targeted approach improves selection accuracy for the specific context while reducing the overall data storage quantity compared to collecting data for all possible cells.

AI summary
A cell selection method and a terminal device. The method includes: A terminal device detects a plurality of cells. The terminal device obtains historical quality of experience QoE of each of N cells. The N cells are all or some of the plurality of cells, N is a positive integer, and the historical QoE is used to represent historical network use experience of the terminal device in each cell. The terminal device selects a first cell from the plurality of cells based on the historical QoE. The terminal device camps on the first cell.
