Enterprise Emergency Call Routing via Location Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for determining the precise location of a mobile communication device within an enterprise environment before making an emergency call are inadequate, as they often rely on coarse-grained location determination, such as country or region, which is insufficient for routing to specific department-level emergency responders.
Innovation Solution
The implementation of an enterprise electronic location system that interacts with the mobile device, utilizing a combination of electronic access-control, asset-tracking, and wireless network-access systems to provide precise location data, enabling the determination of the correct emergency phone number for department-level emergency responses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If coarse-grained location determination (country or region level) is used, then device complexity is reduced, but measurement precision of location is insufficient for department-level emergency routing
Solution Approach 1:
The patent segments the enterprise location space into hierarchical zones (campus-level, building-level, department-level) with corresponding emergency response teams. Each zone has its own emergency phone number, allowing precise routing without requiring a single complex global positioning system. The segmentation enables location precision to be improved at each hierarchical level independently.
Solution Approach 2:
The patent introduces an intermediary enterprise electronic location system that sits between the mobile device and the emergency response network. This intermediary system translates coarse device location data into precise enterprise-zone identification by interacting with access-control, asset-tracking, and wireless-network systems, thereby achieving high measurement precision without directly complicating the mobile device.
2Measurement precision
If multiple location determination systems are integrated, then location precision is improved, but device complexity increases
Solution Approach 1:
The enterprise electronic location system acts as an intermediary that consolidates multiple location determination sources (access-control cards, asset-tracking tags, wireless network triangulation) into a unified location service. Rather than requiring the mobile device to directly integrate and process all these systems, the intermediary handles the complexity of combining multiple data sources to achieve precise location determination.
Solution Approach 2:
The enterprise electronic location system serves multiple functions simultaneously: it determines location for emergency routing, tracks employee movements for security purposes, and provides location-based services for other enterprise applications. This multi-functionality justifies the system complexity by providing comprehensive value beyond just emergency call routing.
3Measurement precision
If precise location determination is implemented, then emergency call routing accuracy is improved, but loss of time for location analysis may increase
Solution Approach 1:
The enterprise electronic location system continuously determines and updates employee location information in the background before emergencies occur, using pre-integrated data from access-control systems, asset-tracking systems, and wireless networks. When an emergency call is initiated, the location information is already available, eliminating any delay in location analysis during the critical call setup phase.
Solution Approach 2:
The location determination operates continuously rather than being triggered only when needed. The system maintains constant awareness of employee locations through ongoing interactions with enterprise infrastructure systems, ensuring that precise location data is always immediately available for emergency routing without requiring additional processing time when an emergency occurs.

AI summary
A method and system are provided for speed-dialling an emergency phone call, from a mobile communication device to an enterprise, based on enterprise location data and a selected enterprise emergency-response service. Enterprise location data can be based on prior interaction between a token, uniquely associated with the mobile communication device, and an enterprise electronic location system. Upon termination, possibly automatic, of a first emergency phone call, a second emergency phone call, to an alternate emergency-response service, can be enabled or automatically dialled.
