Distributed Proxy Cache for Mobile Network Signaling Load Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile networks face increased signaling challenges during high-traffic events like sporting events or elections, with LTE networks offering some relief but still struggling with signaling issues due to increased data demands and resource conservation needs, while existing solutions like traffic optimization can introduce bottlenecks or fail during equipment or capacity issues.
Innovation Solution
A distributed proxy and cache system with fault-tolerant architecture that categorizes and manages mobile traffic, applies caching strategies based on application behavior and network conditions, and implements failover mechanisms to ensure continuous service by reducing unnecessary network requests and optimizing bandwidth use across all service providers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If traffic optimization components are introduced to reduce signaling, then signaling load is reduced, but the system introduces a bottleneck and single point of failure
Solution Approach 1:
The patent segments the traffic optimization functionality into multiple distributed proxy servers instead of using a single centralized component. Each proxy server handles a portion of the traffic optimization tasks, eliminating the single point of failure while collectively reducing signaling load through distributed intelligence
Solution Approach 2:
The patent introduces proxy servers as intermediary components between mobile devices and the core network. These proxies cache content and manage traffic locally, reducing signaling to the core network while maintaining reliability through distributed architecture where multiple proxies can failover for each other
2Speed
If LTE networks are deployed to provide faster speeds and richer services, then network performance is improved, but signaling issues worsen due to increased data demands
Solution Approach 1:
The patent implements content caching in proxy servers before requests reach the core network. By pre-caching frequently accessed content and keeping it locally available, the system prepares data in advance, reducing the need for repeated signaling requests to the core network while maintaining fast access speeds
Solution Approach 2:
The patent creates copies of content in distributed proxy servers located closer to end users. These copies serve local requests without requiring communication with the core network, thereby reducing signaling load while maintaining the high-speed access characteristics of LTE networks
3Quantity of substance
If WiFi network overlays and new hotspots are deployed to prepare for high network use, then network capacity is increased, but device complexity and management overhead increase
Solution Approach 1:
The patent designs proxy servers with multi-functionality, handling content caching, traffic optimization, failover management, and load balancing within a single unified architecture. This universal approach increases network capacity while avoiding the complexity of managing separate systems for each function

AI summary
A mobile device and method to utilize the failover mechanism for fault tolerance provided for mobile traffic management are disclosed. One embodiment includes a method, which may be implemented on a system or a mobile device which responsive to detecting a failed attempt to connect to a proxy server, determines whether the proxy server is reachable In one embodiment, in response to determining that the proxy server is reachable, initiates a failover process by reconfiguring DNS routing rules.
