Solution Overview

Problem

Conventional instant messaging protocols face challenges in maintaining accurate presence information for mobile devices in wireless networks due to intermittent connections, leading to reduced battery life and increased network traffic.

Innovation Solution

An intermediate presence server analyzes traffic between mobile devices and network nodes to differentiate between interactive and background messages, allowing for accurate presence information derivation without significantly increasing network traffic or battery consumption.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If conventional instant messaging protocols send dedicated presence information messages, then presence information accuracy is maintained, but wireless network traffic increases and battery life reduces

Engineering Contradiction:
Improvepresence information accuracyVSAvoidbattery life
Core Design Contradiction:
Measurement precisionVSLoss of energy

Solution Approach 1:

The patent combines presence information transmission with existing message traffic. Instead of sending separate dedicated presence messages, the system piggybacks presence information on regular message exchanges between mobile devices, thereby eliminating additional energy-consuming transmissions while maintaining presence accuracy

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent introduces an intermediary server that monitors and analyzes message traffic between mobile devices. This server derives presence information from the analyzed traffic patterns without requiring the mobile devices to actively report their status, thus reducing energy consumption while maintaining accurate presence information

Inventive Principle:
Principle #24Intermediary (Mediator)

2Measurement precision

If conventional instant messaging protocols send dedicated presence information messages, then presence information accuracy is maintained, but wireless network traffic increases

Engineering Contradiction:
Improvepresence information accuracyVSAvoidwireless network traffic
Core Design Contradiction:
Measurement precisionVSQuantity of substance

Solution Approach 1:

The patent merges presence information transmission with existing message traffic by piggybacking presence data on regular message exchanges. This approach eliminates the need for separate presence messages, thereby reducing overall network traffic while maintaining presence information accuracy

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The intermediary server monitors and analyzes existing message traffic to derive presence information, eliminating the need for additional presence-specific network traffic while maintaining accurate presence information through intelligent analysis of regular communication patterns

Inventive Principle:
Principle #24Intermediary (Mediator)

3Measurement precision

If the mobile device maintains continuous connection to report presence, then presence information accuracy is improved, but battery consumption increases

Engineering Contradiction:
Improvepresence information accuracyVSAvoidbattery consumption
Core Design Contradiction:
Measurement precisionVSUse of energy by moving object

Solution Approach 1:

The patent introduces an intermediary server that passively monitors message traffic to determine presence information. This eliminates the need for the mobile device to maintain continuous active connections or periodically report its status, significantly reducing battery consumption while maintaining accurate presence information through traffic analysis

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system uses the mobile device's own message traffic to automatically indicate its presence state without requiring additional active reporting mechanisms. The device's normal communication patterns naturally reveal its presence status, eliminating the need for extra energy-consuming presence maintenance activities

Inventive Principle:
Principle #25Self-service
