Softphone Emergency Routing via Cloud Platform
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current softphone applications are not geographically flexible, leading to delayed emergency responses when users travel, as they route emergency calls to their home region instead of the user's current location, causing delays in accessing local emergency services.
Innovation Solution
A system and method that implements a softphone emergency dialing architecture, which receives an emergency interaction, validates the user's location, and routes the call through a cloud communication platform to a regional session border controller using current location data, allowing for local emergency services to be contacted with a local calling number.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If softphone application routes emergency calls to home region, then call routing is simplified, but emergency response time is delayed
Solution Approach 1:
The system performs preliminary actions by detecting the user's current location before the emergency call is initiated. The softphone application continuously monitors GPS coordinates and determines the current region in advance, so when an emergency call is made, the routing decision is already prepared, eliminating delay while maintaining simplicity.
Solution Approach 2:
The call routing is made dynamic by transitioning from a static home-region-based routing to a dynamic location-based routing. The system automatically adjusts the routing destination based on real-time location data, allowing the emergency call to be routed to the appropriate local services regardless of the user's current position.
2Loss of time
If softphone application uses location-based routing, then emergency response time is improved, but system complexity increases
Solution Approach 1:
The softphone application performs multiple functions using a single location detection mechanism. The same GPS location data used for general navigation and positioning purposes is also utilized for emergency call routing determination, eliminating the need for separate location detection systems and reducing overall complexity.
Solution Approach 2:
The system introduces a location data structure as an intermediary that serves as a common interface between the GPS detection module and the call routing logic. This standardized data structure simplifies the integration by providing a clear contract for location information exchange, reducing system complexity while enabling location-based routing.
3Measurement precision
If softphone application validates emergency interaction against network switch identifier, then call accuracy is improved, but processing time is increased
Solution Approach 1:
The system performs partial validation by checking only the critical network switch identifier against the expected value for the detected location, rather than performing a comprehensive verification of all location parameters. This selective validation approach maintains sufficient accuracy for emergency routing while minimizing processing time overhead.

AI summary
A computer-implemented method provides for contacting emergency services in a remote region that is different from a home region using a softphone emergency dialing system. The method includes receiving, at a communication interface in the remote region, an emergency communication originating from a softphone application executing on a communication device, the software application being registered in the home region. The method also includes validating, by a computer processor, the emergency communication with a network switch identifier, and accessing a database to identify an originator of the emergency communication, including current location data. The method further includes routing, via a cloud communication platform, the emergency communication to a regional session border controller, and executing, by the computer processor, the emergency communication with a local calling number associated with the remote region.
