Emergency Call Routing via Ledger Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current emergency communication systems face challenges in routing calls from original equipment manufacturer call centers to public safety answering points, especially across different countries, due to varying laws and the lack of direct connections, leading to potential misrouting and inefficiencies in emergency response.
Innovation Solution
A method utilizing a ledger structure to facilitate emergency communications by initiating a normal call from user equipment to a service provider, which transmits data to the ledger and routes the call to the appropriate public safety answering point, ensuring reliable and robust emergency call handling across jurisdictions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a normal call is initiated from user equipment to a service provider for emergency communication, then the call can be routed across different countries and jurisdictions, but the routing complexity increases due to varying laws and lack of direct connections to public safety answering points
Solution Approach 1:
The patent introduces a service provider as an intermediary between the user equipment and public safety answering points. The service provider receives normal calls from user equipment, determines emergency situations, and routes calls to appropriate PSAPs. This intermediary resolves the contradiction by simplifying the routing process for users while handling the complexity of cross-border regulations and connections behind the scenes.
Solution Approach 2:
The system segments the emergency call handling process into distinct components: user equipment initiation, service provider mediation (including ledger structure verification), and PSAP termination. This segmentation allows each component to handle specific tasks independently, reducing overall routing complexity while maintaining cross-border adaptability.
2Productivity
If direct connections are established from original equipment manufacturer call centers to public safety answering points, then emergency response efficiency improves, but legal restrictions in certain countries prevent such direct connections
Solution Approach 1:
The service provider acts as a legal intermediary that complies with local regulations while enabling efficient emergency response. Instead of direct connections being blocked by law, the service provider mediates the connection, allowing OEM call centers to maintain legal compliance in restricted countries while still achieving efficient routing to PSAPs through the intermediary.
Solution Approach 2:
The service provider performs multiple functions: receiving normal calls, determining emergencies, querying the ledger structure for PSAP information, and routing calls. This multi-functional intermediary enables the system to adapt to different legal jurisdictions while maintaining efficient emergency response across all countries.
3Measurement precision
If a ledger structure is used to store public safety answering point information, then call routing accuracy improves, but the system requires additional data transmission steps between service provider and ledger
Solution Approach 1:
The ledger structure pre-stores PSAP information including contact details and routing data before emergencies occur. When an emergency call is received, the service provider only needs to query this pre-prepared information rather than searching or determining PSAP details in real-time, thus improving identification accuracy while minimizing additional time loss through efficient data retrieval.

AI summary
The present invention relates to a method for conducting an emergency communication using a user equipment in a country, or a geographic region within a country, being part of the coverage area of a mobile communication network, wherein, in case of an emergency situation, a normal specific normal call is initiated, by the user equipment, to a service provider, wherein an emergency communication is initiated, from the service provider and in dependency of the location of the user equipment, to a specific public safety answering point, wherein, in order for the emergency communication to be conducted to the specific public safety answering point, a ledger structure is involved and the method comprises the following steps: -- in a first step, the service provider transmits a first set of data to the ledger structure, -- in a second step and in response to receiving the first set of data from the service provider, the ledger structure transmits a second set of data to the service provider, -- in a third step, the specific normal call is routed to the specific public safety answering point and the specific public safety answering point receives at least a third set of data comprising at least part of the first set of data and/or of the second set of data.
