Edge Bandwidth Manager for Radio Access Network State Modeling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing optimizing solutions for 3G and 4G wireless networks lack accurate understanding of Radio Access Network (RAN) conditions, leading to inefficient video or data optimization, potentially causing underutilization or overutilization due to inaccurate modeling of user activity and bandwidth usage.
Innovation Solution
A method and system that intercept and parse control plane messages between the RAN and the core network to determine the current state of the RAN, including bandwidth utilization, user activity, and potential congestion, using an edge bandwidth manager to model the RAN and manage bandwidth dynamically.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If existing optimizing solutions are used for 3G and 4G wireless networks, then network optimization is performed, but accurate understanding of RAN conditions is lacking leading to inefficient optimization
Solution Approach 1:
The patent introduces an Edge Bandwidth Manager (EBM) as an intermediary component that sits between the RAN and core network. The EBM intercepts and parses control plane messages (such as RANAP, GTP, or S1AP protocols) to extract RAN state information including bandwidth utilization, user activity, and congestion status. This intermediary approach enables accurate RAN modeling without disrupting existing network elements, resolving the contradiction by providing precise measurements while maintaining network operation.
2Measurement precision
If control plane messages are intercepted and parsed to determine RAN state, then accurate RAN modeling is achieved, but additional network components and processing are required
Solution Approach 1:
The Edge Bandwidth Manager is designed as a multi-functional component that performs multiple tasks: intercepting control plane messages, parsing protocol data, determining RAN state parameters, modeling bandwidth utilization, and providing optimization decisions. By consolidating these functions into a single universal component, the patent reduces overall system complexity while achieving accurate RAN state measurement.
3Productivity
If dynamic bandwidth management is implemented based on real-time RAN state, then network optimization is improved, but continuous monitoring and processing of control plane messages is required
Solution Approach 1:
The Edge Bandwidth Manager implements selective monitoring by focusing on specific control plane messages and parameters that are most indicative of RAN state changes. Rather than processing all messages equally, the system identifies and analyzes only the critical information needed for bandwidth management decisions, reducing processing overhead and energy consumption while maintaining effective dynamic bandwidth management.
