SON Function Selection via Capability Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In Self-Organizing Networks (SON), entities lack capability information of surrounding entities, leading to executing conflicts during function coordination, affecting cooperation and optimization.
Innovation Solution
A method and system where an SON function selection entity receives and acquires capability information of surrounding SON function entities, using this information and a selection policy to select appropriate SON functions, thereby preventing conflicts and enhancing cooperation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If SON functions are coordinated using conventional methods (conflict avoidance or conflict resolution), then conflict management is achieved, but entities cannot learn SON capability information of surrounding entities, leading to executing conflicts
Solution Approach 1:
The patent implements a feedback mechanism where SON function entities share their capability information with selecting entities. The selecting entity receives capability information from surrounding entities, processes it according to selection policies, and makes coordinated SON function selections. This feedback loop enables entities to learn about surrounding capabilities and avoid conflicts, resolving the information loss problem while maintaining coordination reliability.
Solution Approach 2:
The patent introduces an intermediary selecting entity that mediates between surrounding SON function entities. This intermediary receives capability information from multiple entities, applies selection policies to determine appropriate SON functions, and coordinates their execution. The intermediary acts as a central coordinator that prevents direct conflicts while enabling information sharing across the network.
2Productivity
If multiple SON functions are executed to address network problems, then network optimization is improved, but executing conflicts occur between SON functions of different entities
Solution Approach 1:
The patent applies preliminary action by having entities share their SON capability information before executing SON functions. The selecting entity receives and processes capability information in advance, determines appropriate SON functions based on selection policies, and coordinates their execution. This preliminary information exchange and function selection prevents executing conflicts before they occur, enabling multiple SON functions to be executed reliably for network optimization.
3Device complexity
If SON function entities operate independently with only local configuration knowledge, then system complexity is reduced, but coordinating conflicts arise between entities
Solution Approach 1:
The patent introduces an intermediary selecting entity that mediates between independent SON function entities. Each entity maintains its local configuration knowledge, but the selecting entity receives capability information from multiple entities, applies selection policies, and coordinates their execution. This intermediary approach maintains the simplicity of individual entities while achieving reliable coordination through centralized function selection.
