Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems struggle to efficiently manage multiple frequency band classes, leading to suboptimal allocation of wireless communication devices based on active and idle mode user loads, which can result in poor quality of service and resource inefficiency.
Innovation Solution
A wireless communication system that monitors active and idle mode users across multiple frequency band classes and selects the most suitable band class for each device based on load metrics, ensuring optimal resource allocation and quality of service by transferring band class instructions to wireless access nodes and devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wireless communication devices operate over multiple frequency band classes, then service coverage and flexibility are improved, but system complexity and resource allocation difficulty increase
Solution Approach 1:
The system dynamically changes the operating frequency band parameter based on monitored load conditions. The base station monitors active and idle mode user counts in each band class and selects the optimal band for device operation, transforming a static multi-band capability into a dynamic load-based selection mechanism that reduces system complexity while maintaining versatility
Solution Approach 2:
The system implements feedback by continuously monitoring the number of active and idle mode users in each frequency band class and using this information to make real-time band selection decisions. This closed-loop feedback mechanism enables automatic load balancing without requiring complex manual configuration, resolving the contradiction between versatility and system complexity
2Productivity
If devices are allocated to frequency band classes without load monitoring, then allocation speed is maintained, but quality of service and resource efficiency deteriorate
Solution Approach 1:
The base station performs preliminary monitoring of active and idle mode user counts in each frequency band class before device allocation. This advance preparation of load information enables rapid band selection when devices need allocation, maintaining high allocation speed while ensuring quality service through informed decision-making
Solution Approach 2:
The system automatically monitors load conditions and performs band selection without requiring external intervention or complex allocation algorithms. The base station self-manages the frequency band allocation based on monitored metrics, maintaining operational simplicity and speed while improving service quality through automatic load-aware decisions
3Reliability
If load-based band class selection is implemented, then resource utilization and quality of service are improved, but system complexity and monitoring overhead increase
Solution Approach 1:
The complex monitoring and decision-making function is extracted from individual devices and centralized at the base station. The base station alone performs the monitoring of active and idle mode users and makes band selection decisions, simplifying device complexity while maintaining quality of service through centralized intelligent control
Solution Approach 2:
The base station performs multiple functions including monitoring active users, monitoring idle users, and making band selection decisions within a single centralized entity. This multi-functionality consolidates what would otherwise require multiple separate systems, reducing overall system complexity while achieving load-based quality service
