Solution Overview

Problem

Current wireless networks face challenges in optimizing mobile traffic, particularly in LTE networks, due to increased signaling demands from richer services and applications, which lead to resource conservation issues and inefficient bandwidth usage, especially concerning battery life and network signaling.

Innovation Solution

A distributed proxy and cache system is implemented on both the client and server sides, which categorizes mobile traffic, applies delivery policies based on application behavior, content priority, user activity, and network conditions, and caches content to reduce the need for frequent polling and radio activation, thereby optimizing network usage and conserving resources.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If LTE networks enable richer services and applications, then service functionality is improved, but signaling demands and network congestion increase

Engineering Contradiction:
Improveservice functionalityVSAvoidsignaling demands
Core Design Contradiction:
Adaptability or versatilityVSLoss of energy

Solution Approach 1:

The system performs preliminary classification of mobile traffic into public and private network destinations before transmission. By pre-identifying traffic destined for private networks and routing it accordingly, the system avoids unnecessary signaling exchanges with public network infrastructure, thereby reducing signaling demands while maintaining enhanced service functionality.

Inventive Principle:
Principle #10Preliminary action

2Loss of information

If mobile devices frequently poll for network updates, then data freshness is improved, but battery consumption increases

Engineering Contradiction:
Improvedata freshnessVSAvoidbattery consumption
Core Design Contradiction:
Loss of informationVSUse of energy by moving object

Solution Approach 1:

The system extracts and isolates traffic destined for private networks from the general mobile traffic flow. By separating private network traffic handling from public network protocols, the system eliminates the need for frequent polling mechanisms typically required in public networks, thereby maintaining data freshness for private networks while significantly reducing battery consumption.

Inventive Principle:
Principle #2Taking out (Extraction)

3Adaptability or versatility

If all mobile traffic is routed through public networks, then network compatibility is improved, but bandwidth efficiency deteriorates

Engineering Contradiction:
Improvenetwork compatibilityVSAvoidbandwidth usage
Core Design Contradiction:
Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The system segments mobile traffic into two distinct categories: public network traffic and private network traffic. Each segment is routed through appropriate network infrastructure - public traffic through public networks maintaining compatibility, and private traffic through direct private network connections improving bandwidth efficiency. This segmentation allows simultaneous achievement of network compatibility and bandwidth optimization.

Inventive Principle:
Principle #1Segmentation

AI summary

Systems and methods for cellular or WIFI mobile traffic optimization based on public or private network destination are disclosed. One embodiment includes a mobile device whose traffic is optimized based on destination IP network type where the mobile device includes a local proxy which detects outgoing traffic and determines whether the outgoing traffic is directed towards a public IP network or private IP network. In general, the outgoing traffic is categorized as optimizable for mobile device battery conservation and/or network resource conservation if the outgoing traffic is directed towards the public IP network. The optimization of the outgoing traffic can be performed by a native operating system of the mobile device or an application that is non-native to the native operating system of the mobile device. The optimization can also be in part or in whole performed by a remote proxy in communication with the local proxy on the mobile device
