C-SON Backhaul Bandwidth Management for Small Cell Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high cost of building and deploying small cell network backhaul infrastructure for 5G networks is exacerbated by the need for new infrastructure that differs from existing wireline networks, leading to inefficiencies in resource usage and bandwidth allocation.
Innovation Solution
A Centralized Self-Organizing Network (C-SON) automation platform is employed to monitor backhaul utilization parameters, adjust bandwidth, and manage backhaul infrastructure by mapping User Equipment to backhaul service flows, thereby optimizing bandwidth utilization and reducing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If new backhaul infrastructure is built for 5G small cells, then network performance and bandwidth are improved, but infrastructure cost increases significantly
Solution Approach 1:
The patent merges 5G small cell backhaul traffic with existing cable access network infrastructure, combining wireless and wireline networks to share physical resources. This allows utilization of already-deployed cable infrastructure for 5G backhaul, eliminating the need for separate dedicated infrastructure and reducing overall costs while maintaining required bandwidth performance.
Solution Approach 2:
The patent makes existing cable access infrastructure multi-functional by enabling it to serve both traditional cable access services and 5G small cell backhaul simultaneously. The cable network performs dual roles as both access network and wireless backhaul, maximizing resource utilization and avoiding redundant infrastructure investment.
2Quantity of substance
If wireline infrastructure is leveraged for backhaul, then infrastructure cost is reduced, but network architecture compatibility issues arise
Solution Approach 1:
The patent introduces network functions and interface adaptations as intermediaries between the 5G small cell network and the cable access infrastructure. These intermediary elements handle protocol translation and architecture bridging, enabling compatibility between the different network architectures while allowing direct use of existing wireline infrastructure for backhaul.
3Productivity
If bandwidth is allocated dynamically, then network efficiency is improved, but complexity of bandwidth management increases
Solution Approach 1:
The patent implements feedback mechanisms where the system continuously monitors backhaul utilization parameters and automatically adjusts bandwidth allocation in response to measured conditions. This closed-loop approach enables dynamic optimization of network efficiency while automating the management process to reduce operational complexity.
Solution Approach 2:
The system performs self-configuration and self-optimization of bandwidth allocation based on monitored utilization parameters. The automated bandwidth management operates autonomously without requiring manual intervention, reducing management complexity while maintaining high network efficiency through continuous adaptation to changing conditions.
Data Source
AI summary
A Centralized Self Organizing Network (C-SON) automation platform for managing a backhaul infrastructure in a telecommunication network. The C-SON automation platform monitors one or more backhaul utilization performance indicators corresponding to a backhaul infrastructure, which infrastructure transports data between one or more User Equipment (UE) connected to a small cell and a data network. The C-SON further receives subscriber data for at least one User Equipment (UE) and location data for the at least one UE from at least one Network Function (NF), and maps the at least one UE to a backhaul service flow and the small cell based on the subscriber data and the location data. The C-SON automation platform determines the backhaul utilization performance indicator exceeds a backhaul threshold limit for the backhaul service flow, and adjusts a bandwidth utilization of the backhaul infrastructure based on the backhaul utilization parameter exceeding the backhaul threshold limit.
