Self-Organizing Network Resource Allocation for Frequency Congestion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Self-Organizing Networks (SON) face bandwidth constraints in certain frequency ranges due to increased network usage, particularly when public service entities utilize designated frequencies, leading to congestion and reduced user satisfaction.
Innovation Solution
A common Application Programming Interface (API) for SON tools enables multiple components to communicate and generate updated network configurations based on performance indicators, transitioning users from congested frequency ranges to less congested ones, while preventing return to the original range to ensure availability for public service entities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If public service entities use designated frequency ranges, then availability for public service is improved, but network congestion increases and user satisfaction deteriorates
Solution Approach 1:
The frequency spectrum is segmented into multiple frequency ranges, allowing the system to divide users across different segments. When public service entities occupy a designated frequency range, the system segments remaining users into other available frequency ranges, preventing congestion in any single segment while ensuring public service availability.
Solution Approach 2:
The network dynamically reallocates users between frequency ranges based on real-time conditions. When public service entities begin using a designated frequency range, the system dynamically transitions affected users to alternative frequency ranges, maintaining both public service reliability and overall network productivity through adaptive resource management.
2Productivity
If users are transitioned to different frequency ranges, then network congestion is reduced, but system complexity increases
Solution Approach 1:
The system implements a universal SON tool architecture that can perform multiple functions: monitoring performance indicators, determining congestion conditions, transitioning users between frequency ranges, and preventing return to congested ranges. This multi-functional approach reduces overall system complexity compared to having separate specialized tools for each function.
Solution Approach 2:
The system enables self-service through automatic user transition and prevention mechanisms. When congestion is detected in a frequency range used by public service entities, the system automatically transitions affected users to alternative ranges and implements prevention mechanisms to block return to congested ranges, eliminating the need for manual intervention and reducing operational complexity.
3Productivity
If congestion management mechanisms are implemented, then network performance is optimized, but ease of operation deteriorates
Solution Approach 1:
The congestion management system operates autonomously by automatically monitoring performance indicators, determining when congestion occurs in frequency ranges used by public service entities, transitioning affected users to alternative ranges, and implementing prevention mechanisms. This self-service operation optimizes network performance while maintaining operational simplicity by eliminating the need for manual management interventions.
Solution Approach 2:
The system continuously monitors performance indicators and uses this feedback to automatically adjust user allocations across frequency ranges. When congestion is detected, the feedback loop triggers automatic user transition and prevention mechanism activation, optimizing network performance through real-time adjustments without requiring manual operational intervention.

AI summary
A self-organizing network includes one or more tools. Such tools may be configured to determine, based on one or more performance indicators, that network usage in a first portion of a frequency spectrum satisfies a first usage threshold of the first portion. Such tools may also be configured to transition, in response to the determining, the plurality of users from the first portion to a second portion of the frequency spectrum different from the first portion. Such tools may further be configured to hinder the plurality of users from returning to the first portion from the second portion.
