Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional Self Optimizing Network (SON) features and policy-based congestion control mechanisms operate independently, leading to potential over-compensation and instability in addressing network congestion.
Innovation Solution
A centralized self-optimizing network and policy server coordinates radio frequency congestion control mechanisms affecting all users within a cell with core network congestion control mechanisms associated with individual users, using user equipment measurements and performance indicators to optimize cell coverage and capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If SON features and policy based functions operate independently, then each can execute its congestion control mechanisms autonomously, but this leads to over-compensation and instability in addressing network congestion
Solution Approach 1:
The patent combines independent SON features and policy-based functions into a unified congestion control system. The coordination mechanism integrates radio frequency congestion control (affecting all users in a cell) with core network congestion control (affecting individual users) to work together harmoniously, preventing over-compensation and instability while maintaining autonomous operational capabilities.
2Productivity
If radio frequency congestion control mechanisms are applied to all users in a cell, then cell coverage and capacity can be optimized, but individual user needs and conditions cannot be addressed
Solution Approach 1:
The patent segments congestion control into two distinct layers: radio frequency congestion control that applies to all users in a cell for overall coverage and capacity optimization, and core network congestion control that operates on individual users to address specific user needs and conditions. This segmentation allows both collective and individualized congestion management to coexist effectively.
3Adaptability or versatility
If core network congestion control mechanisms are applied to individual users, then user-specific congestion can be managed, but overall cell coverage and capacity optimization is reduced
Solution Approach 1:
The patent merges radio frequency congestion control (for cell-level optimization) with core network congestion control (for user-specific management) into a coordinated system. The coordination mechanism ensures that both control layers work together synergistically, where radio frequency adjustments optimize overall cell performance while core network mechanisms provide user-specific congestion management, achieving both cell-wide and individual user optimization simultaneously.

AI summary
A centralized self optimizing network and policy server is configured to control congestion within at least one cell in a wireless network by coordinating application of radio frequency congestion control mechanisms affecting all users within the cell and application of core network congestion control mechanisms associated with individual users within the cell.
