Mobile Entity Emergency Call Sensor Data Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing emergency call systems struggle to accurately distinguish between high-priority and false emergency calls due to insufficient information provided by callers, leading to delays in response times that can be critical in life-threatening situations.
Innovation Solution
A method and system that utilize sensors, such as electronic nose, tongue, and eye, to collect additional environmental data during emergency calls, automatically activating these sensors if necessary, and transmitting the data to an emergency call center to enhance the operator's understanding of the situation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If traditional emergency call systems rely solely on caller-provided information, then the system is simple to operate, but the information completeness is insufficient leading to delayed response times
Solution Approach 1:
The system performs preliminary actions by automatically collecting sensor data from the mobile entity before the emergency call is even placed. Environmental sensors (temperature, humidity, light, sound, motion detectors) continuously monitor and store data in the buffer memory, so when an emergency call is initiated, the information is already prepared and ready for immediate transmission to the emergency call center, eliminating the need for the caller to manually describe the environment.
Solution Approach 2:
The mobile entity autonomously activates sensors and collects environmental data without requiring operator intervention or caller input. The processing unit automatically determines when sensor activation is needed, manages the data collection process, and prepares the information for transmission, making the system self-sufficient in gathering critical emergency information.
2Loss of information
If multiple sensors are activated to collect environmental data, then the information quality improves, but the energy consumption increases
Solution Approach 1:
The system dynamically adjusts sensor activation based on real-time conditions rather than continuously operating all sensors. The processing unit monitors environmental parameters and selectively activates only those sensors needed for the current situation, allowing the mobile entity to transition between different operational states (low-power standby vs. active data collection) to optimize energy consumption while maintaining information quality when needed.
Solution Approach 2:
The system changes operational parameters by adjusting sensor activation states based on detected conditions. When environmental anomalies are detected or during emergency calls, the processing unit modifies the activation status of various sensors (temperature, humidity, light, sound, motion detectors) to collect comprehensive data only when necessary, rather than maintaining constant high-energy operation.
3Loss of time
If sensor data is automatically collected and transmitted, then the response time improves, but the device complexity increases
Solution Approach 1:
The system merges multiple functions into integrated components: the processing unit handles both sensor control and data analysis, the buffer memory stores both sensor readings and call information, and the transmission unit sends consolidated packages of caller information plus environmental data. This integration reduces overall system complexity despite the advanced capabilities, as components work together as unified systems rather than separate independent units.

AI summary
The invention provides a method carried out at a mobile entity (100) connected to a cellular network (50), wherein it is deteremiend that an emergency call to an emergency call center (300) has been started at the mobile entity. At least one sensor (80, 81) connected to the mobile entity is selected in response to the determining, the at least one sensor (80, 81) being configured to collect sensor data other than audio data from an environment in which the mobile entity is located. The at least one sensor (80, 81) is activated and the collection of the sensor data is requested. Furthermore the requested sensor data is trasnmitted to the emergency call center (300).
