Emergency Call Redirection via Private Response Center
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In scenarios where calls to private assistance services fail to connect due to network outages or high call volumes, there is a need for a mechanism to quickly redirect users to emergency services like 911 without requiring complex input operations, especially for individuals with impairments or in emergency situations.
Innovation Solution
A communications device with a simplified input interface, such as a single button, that places an initial call to a private response center and, upon failure or rejection, automatically or upon user indication, places a call to emergency services like 911, using predefined signals or prompts, ensuring rapid access to emergency services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a simplified single-button interface is used to initiate calls, then ease of operation is improved, but the ability to distinguish between emergency and non-emergency situations deteriorates
Solution Approach 1:
The system performs preliminary actions by automatically attempting to connect to the private response center first before involving emergency services. The call redirection logic is pre-programmed to follow a specific sequence: attempt private assistance connection, detect failure, then automatically redirect to emergency services, eliminating the need for complex user input while preserving emergency detection accuracy
Solution Approach 2:
The system uses feedback mechanisms to detect call connection status and user responses. By monitoring whether the private response center answers the call or sends a rejection signal, the system gains information about the situation type. User feedback during the call (such as speaking or remaining silent) provides additional context that helps distinguish emergencies from non-emergencies
2Loss of time
If automatic call redirection to emergency services is implemented, then response time is improved, but the risk of unnecessary emergency calls increases
Solution Approach 1:
The system performs preliminary assessment by attempting connection to the private response center before activating emergency services. This preliminary action serves as a filter: if the private center can handle the situation, emergency services are not activated. The pre-programmed redirection logic ensures that only calls that fail to connect to private assistance or receive explicit rejection signals proceed to emergency services, reducing false alarms
Solution Approach 2:
The private response center acts as an intermediary between the user and emergency services. It receives initial calls and performs preliminary assessment, only rejecting calls that require emergency intervention. This intermediary layer filters out non-emergency situations (technical issues, informational needs, etc.) before they reach emergency services, while still enabling rapid escalation when genuine emergencies are detected
3Measurement precision
If the system monitors call connection status and user behavior, then detection accuracy is improved, but device complexity increases
Solution Approach 1:
The communications device leverages existing multi-functional capabilities already present in modern smartphones and telecommunication devices. The same hardware components (microphone, speaker, processor, network interface) used for normal communication are repurposed to monitor call connection status and user behavior during emergency calls. This universal use of existing components achieves detection functionality without adding dedicated hardware complexity
Solution Approach 2:
The system uses self-service mechanisms where the device automatically monitors its own call status and user interactions without requiring external assistance or complex additional systems. The processor continuously checks connection status, and the same interface components used for communication (microphone for voice detection, speaker for audio output) serve dual purposes of normal operation and emergency detection

AI summary
Systems and methods are provided for connecting a caller to an alternate telephone number, such as 911, when a call to a private response center does not result in immediate assistance. In one example, when the call to the private response center does not connect, the communications device used to make the call may prompt the user to indicate that the call relates to an emergency, and the communications device may call the emergency services telephone number. Failure to connect may result when the call does not connect to a receiving party, or upon failure to timely reach a customer service representative. In another example, the call to the private response center may connect, but the private response center may signal the communications device that the call will not be handled immediately. The communications device may then prompt the user to indicate whether an alternate telephone number should be called.
