Mobile Device Data-Only Emergency Reporting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional personal emergency response systems (PERS) and mobile PERS face communication failures due to sequential voice, text, and data transmission, leading to jammed channels and failed reporting when wireless signals are weak, preventing data transmission during voice calls.
Innovation Solution
Implementing a data-only communication method where a mobile device determines network conditions and prioritizes data transmission over voice calls, generating a data-only report to a remote server, which acknowledges the report and initiates a call-back phone call, ensuring reliable emergency event reporting even under weak signal conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If voice, text, and data are transmitted sequentially in traditional PERS, then circuitry can be simplified and device size reduced, but communication channel becomes jammed when one transmission fails, preventing subsequent transmissions
Solution Approach 1:
The patent segments the transmission process by separating voice calls from data transmission. When a voice call is detected, the system automatically suspends data transmission to avoid channel jamming. This segmentation allows each transmission type to operate independently without interfering with the other, resolving the contradiction between simplified circuitry and communication reliability.
Solution Approach 2:
The system dynamically adjusts its transmission behavior based on real-time conditions. When a voice call is detected, the system dynamically suspends data transmission; when the voice call ends, data transmission is automatically resumed. This dynamic adaptation ensures reliable communication without requiring complex static circuitry design.
2Ease of operation
If voice call is made first in sequential transmission, then voice communication is established, but data transmission cannot be initiated until voice call is terminated, causing delays in emergency reporting
Solution Approach 1:
The system performs preliminary detection of voice calls before data transmission begins. By monitoring for voice call establishment in advance, the system can preemptively suspend data transmission to avoid channel jamming. This preliminary action prevents the time loss that would occur if data transmission waited for voice call termination.
Solution Approach 2:
The system maintains continuous monitoring of transmission conditions and automatically resumes data transmission as soon as voice calls end. This continuous action ensures minimal delay in emergency reporting while maintaining the simplicity of sequential transmission architecture.
3Productivity
If data transmission proceeds during voice call, then data can be sent continuously, but communication channel becomes jammed and prevents subsequent transmissions
Solution Approach 1:
The system applies preliminary anti-action by detecting voice calls and preemptively suspending data transmission before channel jamming occurs. This preventive measure eliminates the harmful effect of channel jamming while maintaining high data transmission efficiency during periods when voice calls are not active.
Solution Approach 2:
The system converts the potential harm of channel jamming into a beneficial control mechanism. By monitoring for voice call conditions that would cause jamming, the system uses this information to automatically suspend data transmission, thereby preventing the harmful effect rather than reacting to it after occurrence.

AI summary
A method for data-only communication in emergency includes: receiving, by a mobile device, a press on an SOS button on the mobile device; generating, by the mobile device, a data alert in response to the receipt of the press on the SOS button; determining, by the mobile device, that data transmission is more reliable than voice call under a network condition where data transmission channel and voice transmission channel are sequentially arranged; and generating, by the mobile device, a data-only report to a remote server in response to a determination of the network condition, wherein the data-only report includes the data alert.
