Context-Aware Traffic Routing for Network Congestion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Service provider networks face challenges in dynamically handling network traffic based on its nature and conditions within the access network, limiting their ability to concurrently provide multiple services to users, such as content filtering and quality of service management.
Innovation Solution
A system and method that utilize a RAN modeling server to monitor and analyze traffic, detecting conditions like congestion, and a content distribution system to dynamically route traffic, adjust data rates, and apply content filtering, ensuring optimal network throughput and quality of service.

Engineering Contradiction Analysis
1Object-affected harmful factors
If service provider networks provide content filtering service to user devices, then content security is improved, but network throughput and service versatility deteriorate
Solution Approach 1:
The patent segments network traffic into different categories (e.g., voice, video, data) and applies different quality of service policies to each segment. This allows content filtering to be applied selectively to specific traffic types without blocking all traffic, thereby maintaining network throughput while ensuring content security for relevant services.
Solution Approach 2:
The patent implements local quality by applying different quality of service parameters to different traffic flows and user devices based on their specific needs and conditions. This enables tailored content filtering and throughput management for each user or service type, preventing blanket filtering that would reduce overall network productivity.
2Reliability
If service provider networks provide quality of service management to user devices, then service quality is improved, but device complexity and operational difficulty increase
Solution Approach 1:
The patent implements self-service by enabling user devices to autonomously report their service quality conditions (such as packet loss, jitter, or latency) to the network. The network then automatically adjusts quality of service policies based on these reports without requiring complex manual configuration or intensive operational intervention, thereby maintaining high service quality while reducing management complexity.
3Adaptability or versatility
If service provider networks dynamically handle traffic based on access network conditions, then network adaptability is improved, but measurement and detection difficulty increase
Solution Approach 1:
The patent implements feedback by establishing a mechanism where user devices continuously report their network conditions (such as signal strength, packet loss, or throughput) back to the network operator. This feedback loop enables the network to dynamically detect and respond to changing conditions in real-time, improving adaptability while simplifying detection through standardized reporting protocols rather than complex monitoring systems.
Data Source
AI summary
A server device may store policy information that includes subscription information associated with one or more user devices, and an indication of how to route traffic upon detecting traffic associated with the one or more user devices associated with the stored subscription information. The server device may receive information associated with a particular traffic flow, where at least some of the received information is derived from the particular traffic flow. The server device may compare the received information to the stored policy information. The server device may detect, based on the comparing, that the particular traffic flow is associated with a particular one of the one or more user devices associated with the stored subscription information. The server device may route the particular traffic flow based on the stored policy information.
