Wireless Terminal Device Multi-Gateway Packet Segregation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless terminal devices (WTDs) are limited by the 'at most one Internet Gateway at a time' policy, which restricts their ability to maintain internet access during outages or when multiple internet gateways are unavailable, leading to suboptimal Quality of Service (QOS) for different types of data streams.
Innovation Solution
Implementing a method in WTDs to classify packets as non-media-stream (NMS), audio, or video data and dynamically switch between multiple Wireless Internet-Access Gateways (WIAGs) based on their specific QOS capabilities, ensuring that NMS, audio, and video packets are transmitted through the most suitable WIAGs for optimal performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a WTD connects to only one Internet Gateway at a time, then device complexity and connection management are simplified, but reliability and continuity of internet access deteriorate during outages or gateway failures
Solution Approach 1:
The patent segments the single internet connection into multiple parallel connections to different Internet Gateways. Each gateway connection is managed independently with its own packet routing rules, allowing the system to maintain multiple simultaneous connections rather than switching between single connections, thereby improving reliability while distributing management complexity across standardized connection modules
Solution Approach 2:
The WTD is designed to perform multiple gateway connection functions simultaneously, making the device capable of maintaining connections to multiple Internet Gateways at once. This multi-functionality allows the device to switch between gateways or use them in parallel based on conditions, improving reliability without requiring separate dedicated systems for each gateway
2Device complexity
If all data packets are transmitted through a single Internet Gateway, then connection management is simplified, but Quality of Service for different data types (NMS, audio, video) deteriorates due to lack of optimized routing
Solution Approach 1:
The patent segments the packet routing system into specialized channels for different data types (NMS, audio, video). Each data type is routed through specific Internet Gateways based on QOS requirements, with separate routing rules and priority levels for each segment, thereby achieving precise QOS control while maintaining manageable complexity through standardized segmentation rules
Solution Approach 2:
The system applies local quality optimization by assigning specific Internet Gateways to specific data types based on their QOS capabilities. Each gateway connection is configured with tailored routing rules that optimize performance for particular data types (e.g., video gateways with higher bandwidth, audio gateways with lower latency), achieving precise QOS precision without requiring complete redesign of the entire routing system
3Reliability
If the WTD switches between multiple Internet Gateways, then reliability and QOS are improved, but device complexity and connection management overhead increase
Solution Approach 1:
The patent implements dynamic gateway selection and packet routing based on real-time conditions such as gateway availability, QOS requirements, and data type. The system can dynamically switch between gateways or adjust routing rules without manual intervention, improving reliability while managing complexity through automated dynamic adaptation rather than static complex configuration
Solution Approach 2:
The WTD incorporates self-service mechanisms that automatically monitor gateway status, classify packets, and route them through appropriate gateways without external control. The system self-manages the complexity of multi-gateway operations through automated classification, routing decisions, and failover protocols, reducing the burden of manual management while maintaining high reliability
