USSD Short Data Message Transmission for Mission Critical Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cellular data communications for mission-critical messages often face delays or failures due to reliance on TCP/IP networks, which are not real-time and can be expensive, and traditional methods like SMS are slow and unreliable.
Innovation Solution
A wireless device equipped with a transceiver, sensors, and a processor that uses cellular signaling systems, such as GSM's USSD, to transmit and process short data messages in real-time, eliminating the need for TCP/IP headers and providing 128-bit encryption for secure, carrier-agnostic communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If TCP/IP communications over core IP network are used for Short Message Service, then data transmission capability is improved, but transmission reliability deteriorates due to failures and delays
Solution Approach 1:
The patent introduces an intermediary mechanism by transmitting data messages embedded within SMS signaling messages through the SMS infrastructure rather than direct TCP/IP communication. This intermediary approach leverages the established SMS network path to carry data payloads, thereby maintaining transmission capability while improving reliability by utilizing the proven SMS delivery mechanism.
2Adaptability or versatility
If store and forward technology is used for SMS transmission, then network coverage is improved, but real-time transmission capability deteriorates
Solution Approach 1:
The system performs preliminary actions by pre-establishing SMS signaling connections and preparing message pathways before actual data transmission is needed. The embedded data messages are ready to be forwarded immediately when signaling messages are exchanged, eliminating the delay associated with traditional store-and-forward approaches while maintaining broad network coverage.
3Adaptability or versatility
If dial-up data service is used, then connection availability is improved, but connection speed deteriorates due to slow sync time
Solution Approach 1:
The patent extracts the data transmission function from traditional dial-up protocols and embeds it within SMS signaling messages. This extraction eliminates the need for slow dial-up connection establishment and synchronization processes, achieving fast data transmission while maintaining the availability benefits of established cellular network infrastructure.
4Reliability
If point-to-point data circuits are used, then transmission reliability is improved, but cost deteriorates to prohibitively expensive levels
Solution Approach 1:
The system applies universality by using the existing SMS infrastructure for dual purposes: traditional text messaging and embedded data message transmission. This multi-functionality allows the patent to achieve reliable point-to-point data transmission without requiring dedicated expensive data circuits, as the SMS network already provides the necessary reliable delivery mechanism.
