Listening-Side Radio Proxy Emergency Call System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radio apparatuses fail to ensure emergency calls can be made in situations where the device is unable to function, such as when the battery is removed or the device is dropped during an emergency, as they rely on the device itself to initiate the call through voice recognition.
Innovation Solution
A radio communication system where a listening-side radio apparatus can wirelessly communicate with a speaking-side radio apparatus to detect emergency situations and make an emergency call on behalf of the speaking-side apparatus using proxy call information, including identification ID and GPS position, even if the speaking-side device is incapacitated.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the radio apparatus relies on itself to initiate emergency calls through voice recognition, then the device structure remains simple, but the emergency call reliability deteriorates when the device is incapacitated
Solution Approach 1:
The patent introduces a listening-side radio apparatus as an intermediary that monitors the speaking-side radio apparatus. When the speaker is in danger, the listening device detects the scream through voice recognition and initiates the emergency call on behalf of the incapacitated speaker, thereby improving emergency call reliability without requiring the speaker's device to be fully functional
Solution Approach 2:
The patent implements preliminary action by having the listening-side radio apparatus continuously monitor the speaking-side apparatus during active calls. The system prepares for potential emergencies by maintaining voice recognition capabilities ready to detect screams and automatically initiate emergency calls before the speaker can act, thus improving reliability without adding complexity to the speaker's device
2Ease of operation
If the radio apparatus automatically initiates emergency calls through voice recognition, then the ease of operation is improved, but the reliability deteriorates when the device cannot function
Solution Approach 1:
The listening-side radio apparatus serves as a mediator that takes over the emergency call initiation function when the speaker's device fails. It monitors the call, detects screams through voice recognition, and automatically places emergency calls using the speaker's contact information, thereby maintaining ease of operation while ensuring reliability even when the speaker's device is incapacitated
3Reliability
If proxy call information is transmitted during communication, then the emergency call reliability is improved, but the loss of information increases due to additional data transmission requirements
Solution Approach 1:
The patent extracts only the essential proxy call information needed for emergency calls (contact information for emergency contacts) from the full communication data. This minimized information set is transmitted during active calls to the listening-side apparatus, improving emergency call reliability while minimizing information loss and transmission overhead by including only the critical data elements
Data Source
AI summary
A radio apparatus includes a communication unit configured to wirelessly communicate with a radio apparatus at the other end of the communication, a proxy call information acquisition unit configured to acquire proxy call information from the radio apparatus at the other end through the radio communication, the proxy call information being information that is required in case of an emergency of the radio apparatus at the other end, and a proxy call unit configured to make an emergency call on behalf of the radio apparatus at the other end based on the proxy call information.
