Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In a network environment with multiple cells, existing technologies face challenges in efficiently selecting or reselecting the optimal cell, particularly when dealing with unlicensed cells and non-terrestrial cells.
Innovation Solution
An electronic device is equipped with a processor that identifies supported frequency bands, receives system information from a base station, determines whether neighbor cells are unlicensed or non-terrestrial, and adjusts frequency priorities based on this information to select the most suitable cell.

Engineering Contradiction Analysis
1Reliability
If existing cell selection technologies are used in networks with multiple cell types, then cell selection can be performed, but efficient selection of optimal cells (particularly unlicensed and non-terrestrial cells) cannot be achieved
Solution Approach 1:
The patent implements dynamic frequency priority adjustment where the electronic device modifies frequency priorities based on real-time identification of cell types (unlicensed, non-terrestrial). The processor dynamically updates priority values in response to detected cell characteristics, enabling adaptive cell selection that optimizes network performance for diverse cell types rather than using static priority assignments.
Solution Approach 2:
The patent changes the parameter of frequency priority values based on cell type identification. When unlicensed or non-terrestrial cells are detected, the processor adjusts the priority parameters associated with their frequency bands, thereby optimizing cell selection for these specific cell types. This parameter modification enables the system to adapt to different network environments and cell configurations.
2Productivity
If frequency priority is determined without considering cell type, then simple selection is possible, but optimal network performance cannot be ensured in diverse network environments
Solution Approach 1:
The patent performs preliminary identification of cell types (unlicensed, non-terrestrial) and their frequency bands before final cell selection. By analyzing cell characteristics in advance and determining appropriate frequency priorities beforehand, the system optimizes network performance without adding significant complexity to the selection process. This preliminary analysis enables informed decision-making for cell selection.
