Solution Overview

Problem

Existing methods for real-time image data transmission between mobile communication terminals are inefficient, leading to inaccurate information transfer, especially in environments with poor communication sensitivity, as they rely on voice communication and do not effectively transmit visual data in a manner that mimics real-time drawing.

Innovation Solution

A method that establishes a Point-To-Point communication channel between mobile communication terminals using a Packet Data Serving Node through a Packet Data Core Network, enabling real-time transmission of image data by scanning and transmitting coordinates, color, and thickness information, allowing clients to display the drawing process in real-time.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If voice communication is used to exchange information, then communication can be established between mobile terminals, but information transfer accuracy deteriorates especially in environments with bad communication sensitivity

Engineering Contradiction:
Improveinformation transfer accuracyVSAvoidcommunication sensitivity
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces voice-based acoustic communication with visual image-based communication. Instead of transmitting information through sound waves that are affected by communication sensitivity, the system transmits information through images that can be clearly displayed and recognized even in poor communication environments, thereby improving information transfer accuracy

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent creates visual copies of information in the form of images that can be transmitted between terminals. By converting information into visual image representations and transmitting these images, the system enables accurate information transfer that is independent of voice communication quality and communication sensitivity

Inventive Principle:
Principle #26Copying

2Reliability

If real-time image data transmission is implemented, then information transfer accuracy improves, but data transmission complexity increases

Engineering Contradiction:
Improveinformation transfer accuracyVSAvoiddata transmission complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent segments the image data transmission process into distinct components: image capture, image processing, data encoding, and transmission. By dividing the complex task of real-time image transmission into manageable segments, the system achieves accurate information transfer while keeping the implementation complexity controllable through modular design

Inventive Principle:
Principle #1Segmentation

AI summary

Disclosed is a method for transmitting image data in real-time between mobile communication terminals in a mobile communication system, the mobile communication system including a host mobile communication terminal, at least one client mobile communication terminal, an SMS server, and a PDSN assigning IP addresses. The method includes when an IP address is received from the PDSN, transmitting by the host mobile communication terminal an invite message to the client mobile communication terminal via the SMS server; receiving by the client mobile communication terminal an IP address from the PDSN, and transmitting a register message to the host mobile communication terminal via the PDSN; updating by the host mobile communication terminal a buddy list, and transmitting the updated buddy list to the client mobile communication terminal via the PDSN; and exchanging by the host and the client mobile communication terminals the image data in real-time based on the updated buddy list.
