Cell Selection Method for Mobile Terminals Optimizing Throughput
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile communication standards do not allow mobile terminals to actively query the communication ability of cells before camping, leading to potential mismatch in performance, affecting data throughput due to factors like network resources and signal interference.
Innovation Solution
A cell selection method that evaluates candidate cells based on their communication abilities, network resources, and signal environment parameters to select the most suitable camping cell, involving sorting and prioritization of cells supporting technologies like 5G, carrier aggregation, and QAM, as well as considering bandwidth and signal strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If mobile terminal selects camping cell mainly according to signal strengths, then cell selection is simple and fast, but data service throughput may be poor due to mismatch in communication ability and network resources
Solution Approach 1:
The patent segments the cell selection process into multiple stages: first filtering cells based on communication ability (5G, 4G, 3G capabilities), then filtering based on network resources (bandwidth, frequency band), and finally selecting based on signal strength. This segmentation allows the mobile terminal to systematically evaluate multiple factors without overwhelming complexity, resolving the contradiction between throughput optimization and selection simplicity.
Solution Approach 2:
The patent applies preliminary action by pre-filtering candidate cells according to communication ability and network resources before final selection based on signal strength. The mobile terminal proactively queries and evaluates cell capabilities in advance, ensuring that the selected cell matches the terminal's communication requirements and available network resources, thereby improving throughput while maintaining a structured selection process.
2Productivity
If mobile terminal does not actively query communication ability of cells, then cell selection process is simple, but performance matching between terminal and cell is poor affecting throughput
Solution Approach 1:
The patent implements feedback mechanisms where the mobile terminal actively queries cell information including communication ability and network resources before camping. The terminal receives feedback about cell capabilities (5G support, carrier aggregation, QAM modulation) and network resources (bandwidth, frequency band) and uses this information to make informed selection decisions, ensuring performance matching while maintaining a manageable detection process through standardized query protocols.
3Productivity
If different cells support same communication technology, then technology compatibility is ensured, but network resources like bandwidth may differ affecting throughput
Solution Approach 1:
The patent applies local quality by evaluating specific network resource characteristics (bandwidth, frequency band) of individual cells rather than treating all cells of the same technology uniformly. The mobile terminal examines the specific qualities of each candidate cell's network resources and selects the cell that best matches both the terminal's capabilities and the available resources, optimizing throughput while adapting to the specific conditions of each cell.

AI summary
A cell selection method and user equipment (UE) are provided. The cell selection method is applied to the UE. The cell selection method includes the steps of obtaining a candidate cell group; selecting a first candidate cell sub-group from the candidate cell group according to the communication ability supported by each candidate cell of the candidate cell group; and selecting a camping cell of the UE from the first candidate cell sub-group.
