Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems struggle to efficiently select cells that align with the specific features and usage purposes of electronic devices, leading to suboptimal wireless communication performance.
Innovation Solution
An electronic device is equipped with communication circuitry and processors that scan multiple frequencies, configure priorities based on device features, and update these priorities to preferentially select cells that match the device's usage purposes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the electronic device selects a cell with priority based on historical connection frequencies, then the device can achieve relatively fast wireless communications, but the selected cell may be incompatible with the current usage purpose of the device
Solution Approach 1:
The patent applies dynamics by making the cell selection priority adaptive rather than static. The priority of frequencies is dynamically adjusted based on real-time detection of device usage purposes (e.g., voice call, video call, data transmission). When a usage purpose is detected, the system temporarily adjusts frequency priorities to favor cells compatible with that specific usage, then restores historical priority rankings after the usage session ends. This resolves the contradiction by allowing the system to switch between speed optimization (using historical priorities) and adaptability optimization (using usage-based priorities) as needed.
Solution Approach 2:
The patent changes the parameter of frequency priority ranking based on detected usage purposes. When usage purpose detection indicates a specific application (e.g., video conferencing), the system modifies the priority parameters of available frequencies to select cells optimized for that usage type. This parameter change enables the system to balance communication speed with usage compatibility, resolving the technical contradiction between maintaining fast communications and adapting to current device needs.
2Adaptability or versatility
If the electronic device performs comprehensive cell selection based on multiple frequency scans, then the device can identify the most suitable cell for its usage purpose, but the cell selection process becomes more time-consuming
Solution Approach 1:
The patent applies preliminary action by pre-establishing a frequency list and initial priority rankings based on historical connection data before actual cell selection is needed. When the device needs to select a cell, it starts with these pre-sorted frequency lists rather than performing a complete scan from scratch. The system only performs additional targeted scans for frequencies that need adjustment based on current usage purposes. This preliminary preparation significantly reduces the time required for comprehensive cell selection while maintaining high suitability.
Solution Approach 2:
The patent uses partial action by performing frequency scans selectively rather than comprehensively. Instead of scanning all possible frequencies, the system focuses scans on specific frequency ranges and cells that are most likely to be suitable based on historical data and current usage context. This partial scanning approach maintains adequate cell suitability while dramatically reducing selection time compared to exhaustive scanning of all frequencies.
3Loss of time
If the electronic device uses stored frequency lists for cell selection, then the device can quickly identify potential cells, but the selection may not account for changes in device features or usage requirements
Solution Approach 1:
The patent implements feedback by continuously monitoring device usage purposes and using this information to adjust frequency priorities in real-time. The usage purpose detection mechanism provides feedback about current device needs, which then feeds back into the frequency priority adjustment process. This closed-loop feedback system ensures that cell selection remains aligned with actual device features and usage requirements, resolving the contradiction between quick selection based on stored lists and adaptive selection based on current needs.

AI summary
An electronic device includes communication circuitry, one or more processors including processing circuitry, and memory storing instructions. The instructions, when executed by the one or more processors individually or collectively, cause the electronic device to perform a scan related to multiple frequencies included in a frequency list related to cell selection, configure priorities of the multiple frequencies based on a result of the scan, update the priorities of the multiple frequencies based on at least one feature of the electronic device, and perform the cell selection based on the updated priorities of the multiple frequencies.
