Emergency Call Messaging Subsystem for PSAP Fallback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing emergency call systems fail to effectively handle call failures, leading to a lack of communication in critical situations, as they do not provide a reliable method for notifying authorities or assisting callers when a voice trunking path is unavailable, resulting in potential delays or misallocation of resources.
Innovation Solution
A messaging subsystem is launched to prompt callers for information about their emergency situation, generating a messaging object containing their location, identity, and emergency details, which is then forwarded to relevant entities via data or voice communication paths, ensuring that critical information is conveyed even if the initial call fails.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a voice trunking path is unavailable to a PSAP, then emergency call delivery fails, but implementing alternative messaging paths adds system complexity
Solution Approach 1:
The patent introduces a messaging subsystem as an intermediary component that bridges the gap between callers and PSAPs when voice trunking paths are unavailable. This mediator captures caller information through text-based messaging and forwards it to the PSAP, ensuring emergency communication continuity without requiring complete voice path availability.
Solution Approach 2:
The system performs preliminary actions by establishing alternative messaging paths in advance of voice path failures. The messaging subsystem is pre-configured to capture caller location, device identity, and emergency details before voice connectivity is lost, enabling seamless fallback to text-based communication when voice trunks become unavailable.
2Loss of time
If emergency call information is lost due to connection failure, then resource allocation is delayed, but implementing comprehensive information capture increases processing requirements
Solution Approach 1:
The messaging subsystem performs preliminary information capture by automatically collecting caller location, device identity, and emergency situation details before voice connectivity is lost. This pre-capture approach ensures critical information is preserved even when voice paths fail, eliminating delays in resource allocation without requiring complex post-failure information gathering.
Solution Approach 2:
The system implements self-service by automatically populating the messaging object with available caller information from network databases and signaling data. This automated information gathering reduces the need for manual data entry and minimizes processing requirements while ensuring comprehensive emergency details are captured and forwarded to the PSAP.

AI summary
An emergency call failure mitigation apparatus, system and method includes a messaging subsystem that may be launched, upon receiving a call signaling indication pursuant to an emergency service call from a calling party that has failed to reach a local Public Safety Answering Point (PSAP). The messaging subsystem is operative to prompt the calling party to provide one or more responses relating to the emergency situation and generate a messaging object including at least one of the calling party's location, identity of a call receiving device associated with the calling party, type of the calling party and priority of the emergency service call determined based on one or more responses of provided by the calling party. In one embodiment, the messaging object may be forwarded to an entity operative to reach the calling party.
