Real-Time Image Data Transmission Between Mobile Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for mobile communication terminals fail to accurately transmit information, especially in environments with poor communication sensitivity, as voice-based information transfer can be inaccurate and prone to errors.
Innovation Solution
A method for real-time image data transmission between mobile communication terminals using a mobile communication system with a host terminal, client terminals, an SMS server, and a Packet Data Serving Node (PDSN) via Point-To-Point (P2P) protocol connections, allowing for the exchange of image data through updated buddy lists and direct board applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If voice-based information transfer is used between mobile communication terminals, then communication simplicity is maintained, but information transfer accuracy deteriorates
Solution Approach 1:
The patent uses image capture to create a visual copy of information (text, numbers, location data) and transmits this visual representation between terminals. The captured image serves as an accurate replica of the original information, eliminating misinterpretation issues inherent in voice-based transfer while maintaining ease of use through simple camera-based input.
2Measurement precision
If real-time image data transmission is implemented between mobile terminals, then information transfer accuracy is improved, but system complexity increases
Solution Approach 1:
The patent introduces an image processing server as an intermediary that receives captured images from mobile terminals, processes them to extract information, and facilitates accurate transmission between terminals. This mediator handles the complex processing tasks centrally, allowing individual terminals to remain relatively simple while achieving high information transfer accuracy through the coordinated system.

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.
