Dynamic Network Congestion Mitigation via Adaptive Message Formatting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Network congestion in packet-based mobile cellular networks leads to issues such as dropped calls, time-outs, and web access problems due to physical limitations like available spectrum and technology constraints at cell sites, especially during high usage.
Innovation Solution
A system that determines network congestion status and adjusts message formats and access based on the connection mechanism, granting full access if not congested and limited access if congested, using less resource-intensive formats for direct connections like 3G or 4G and more resource-intensive formats for indirect connections like Wi-Fi or femtocell.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If full access is granted to devices on the network, then network utilization and service quality are improved, but network congestion worsens due to physical limitations of cell sites
Solution Approach 1:
The patent implements dynamic access control by adjusting message formatting and delivery mechanisms based on real-time network congestion status. When congestion is detected, the system dynamically switches to more efficient message formats and prioritizes critical communications, allowing the network to adapt its capacity to current load conditions rather than operating at fixed capacity levels
Solution Approach 2:
The system changes message format parameters (such as compression level, detail granularity, and protocol overhead) based on network congestion status. By modifying these parameters dynamically, the network can maintain higher utilization during low-congestion periods while reducing resource consumption during high-congestion periods, effectively resolving the contradiction between productivity and reliability
2Loss of information
If resource-intensive message formats are used for indirect connections (Wi-Fi, femtocell), then message completeness and quality are improved, but network resource consumption increases
Solution Approach 1:
The patent applies different message formatting qualities to different connection types based on their characteristics. Indirect connections (Wi-Fi, femtocell) receive resource-intensive formatted messages with complete information, while direct connections (3G, 4G) receive optimized formats. This local differentiation ensures each connection type receives appropriate quality without unnecessarily consuming network resources
Solution Approach 2:
The system applies partial action by sending only the necessary level of message detail for each connection type. Rather than sending full-detail messages to all devices, the system sends compressed or summary formats to direct connections where bandwidth is more constrained, reserving resource-intensive formats only for indirect connections that can handle them, thus avoiding excessive resource consumption
3Productivity
If congestion monitoring and adaptive formatting are implemented, then network efficiency is improved, but system complexity increases
Solution Approach 1:
The patent implements feedback mechanisms where the network monitors its own congestion status and uses this information to adjust message formatting and access control decisions. This closed-loop feedback system automatically optimizes network efficiency without requiring complex manual intervention, as the monitoring and adaptation are integrated into the existing network infrastructure
Solution Approach 2:
The network system performs self-service by automatically monitoring its own congestion status and making adaptive formatting decisions without external control. The network entities themselves generate and process congestion information, and the formatting adjustments are made autonomously based on predefined criteria, reducing the need for complex external management systems

AI summary
Cell site congestion may result in dropped calls, time-outs on data sessions, web access problems, or the like. A network congestion status may be used to minimize network congestion. In an example embodiment, messages which are distributed via a network may be formatted based on the network's congestions status and a device's connection mechanism. Further, a network access may be based on the network's congestion status and on a device's connection mechanism.
