Network Coordination Apparatus for SON Conflict Resolution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current network management in wireless communication systems, particularly in Self-Organizing Networks (SON), faces challenges in efficiently handling conflicts between dynamic and individual SON function instances, leading to potential interference and the need for manual, time-consuming, and error-prone operational management.
Innovation Solution
A method and apparatus for determining event criteria, impact, and interference with implemented function instances, generating a coordination output to avoid conflicts by acknowledging or modifying event requests, and applying coordination rules to manage spatial and temporal interferences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual and semi-automated management workflows are used for network configuration and optimization, then expertise and control can be applied, but the process becomes time-consuming, error-prone, and expensive
Solution Approach 1:
The system implements self-service through automated SON functions that autonomously perform network configuration, optimization, and troubleshooting without human intervention. The coordination apparatus enables these functions to self-manage by detecting conflicts between multiple SON functions and automatically resolving them through predefined coordination rules, eliminating the need for manual expert operations while maintaining high reliability
Solution Approach 2:
The system employs feedback mechanisms where the coordination apparatus continuously monitors the status and interactions of multiple SON function instances. When conflicts are detected between functions operating on the same network elements, the system uses feedback loops to trigger conflict resolution processes that adjust function parameters or execution timing, ensuring accurate network management through iterative self-correction
2Adaptability or versatility
If multiple SON function instances are deployed to handle complex network management tasks, then functionality and adaptability are improved, but conflicts and interferences between functions increase
Solution Approach 1:
The coordination apparatus serves as an intermediary layer between multiple SON function instances and the network elements they manage. It mediates conflicts by receiving status information from various functions, detecting potential interferences through coordination rules, and automatically resolving conflicts by adjusting function execution parameters or timing, thereby enabling multiple functions to operate simultaneously without harmful interactions
Solution Approach 2:
The system segments the network management functionality into distinct, independently manageable SON function instances, each responsible for specific tasks. The coordination apparatus further segments the conflict resolution process into discrete steps: detection, analysis, and resolution. This segmentation allows individual functions to be optimized for specific purposes while the coordination layer manages their interactions, preventing interference through structured separation of concerns
3Speed
If dynamic SON functions are executed individually and autonomously, then responsiveness to network changes is improved, but coordination and conflict avoidance become difficult
Solution Approach 1:
The coordination apparatus implements preliminary action by establishing coordination rules and conflict detection mechanisms before multiple SON functions are deployed. These pre-configured rules define acceptable interactions between functions and potential conflict scenarios. When functions are dynamically executed, the coordination system already has the framework in place to quickly detect and resolve conflicts, maintaining fast response times while managing complexity through pre-planned coordination strategies

AI summary
A method comprising determining at least one event criteria from a received event function request; determining an event impact from the at least one event criteria and a general function impact; determining whether the event impact interferes with at least one implemented function instance; and generating a coordination output based on the determination whether the event impact interferes.
