Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile communication systems face inefficiencies in frequency utilization and base station control due to the lack of specific methods for specifying operating frequency band positions for mobile stations with different frequency bandwidths, leading to increased communication congestion and reduced power consumption in mobile stations.
Innovation Solution
A method for efficiently mapping operating frequency bands in mobile stations based on their unique frequency bandwidths and identification information, allowing for reduced communication traffic and power consumption by grouping mobile stations and using specific frequency positions for paging and access, thereby improving frequency utilization and base station control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If mobile stations use different frequency bandwidths, then frequency utilization efficiency is improved, but base station control complexity increases
Solution Approach 1:
The frequency band is segmented into multiple frequency positions, and mobile stations are divided into different groups based on their identification information. Each group is assigned to a specific frequency position, allowing mobile stations with different frequency bandwidths to operate efficiently while simplifying base station control through structured grouping and assignment.
Solution Approach 2:
The patent changes the parameter of frequency position assignment based on mobile station identification information and frequency bandwidth characteristics. By dynamically assigning frequency positions according to these parameters, the system achieves improved frequency utilization while maintaining manageable base station control through rule-based assignment.
2Reliability
If mobile stations monitor all frequency bands, then paging reliability is improved, but power consumption increases
Solution Approach 1:
Instead of monitoring all frequency bands uniformly, mobile stations monitor only the specific frequency position assigned to their group. This localized monitoring approach maintains paging reliability for the target group while significantly reducing power consumption by avoiding unnecessary monitoring of other frequency bands.
Solution Approach 2:
The patent extracts the essential paging monitoring function from universal full-band monitoring and concentrates it on specific frequency positions. Mobile stations take out only the necessary frequency position monitoring required for their group, eliminating redundant monitoring activities and reducing power consumption while preserving paging reliability.
3Device complexity
If frequency band positions are not specifically assigned, then system simplicity is maintained, but communication congestion increases
Solution Approach 1:
The system segments frequency band positions and assigns them to different mobile station groups based on identification information. This segmentation prevents communication congestion by distributing traffic across multiple frequency positions while maintaining system simplicity through automated, rule-based assignment mechanisms that do not require complex centralized control.
Solution Approach 2:
Mobile stations automatically determine their assigned frequency position based on their identification information and frequency bandwidth characteristics without requiring complex base station control. This self-service approach maintains system simplicity while improving communication efficiency by eliminating the need for detailed frequency assignment negotiations and reducing control overhead.
