Dynamic Routing of Special Number Calls to Multiple Agencies
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current telecommunication systems are inadequate in simultaneously routing special number calls, such as 9-1-1 calls, to multiple agencies as the caller's location and assistance requirements change, often requiring reevaluation and reallocation of resources during the call.
Innovation Solution
A system and method that utilizes an unlicensed mobile access network and a radio access network, coupled with a mobile switching facility and a special number call receiving facility, which includes a location determining facility to dynamically route the call to appropriate agencies based on the caller's location and changing assistance needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a special number call is routed to a single receiving facility, then the call routing is simple and direct, but the system cannot adapt when the caller's location or assistance requirements change
Solution Approach 1:
The system dynamically routes special number calls to multiple receiving agencies simultaneously based on real-time caller location and assistance requirements. The mobile switching facility and location determining facility enable the routing configuration to change during the call without requiring call termination and re-establishment, making the system adaptive to moving objects and changing conditions.
Solution Approach 2:
The call routing function is segmented into multiple independent receiving agencies that can be activated simultaneously. Instead of a single receiving facility, the system divides the receiving capacity across multiple agencies (e.g., fire, police, EMS), allowing selective routing to different agencies based on the specific emergency type and caller location.
2Reliability
If the system routes calls to multiple agencies simultaneously, then assistance coverage is improved, but system complexity and resource coordination requirements increase
Solution Approach 1:
The mobile switching facility serves multiple functions: it routes calls to the special number call receiving facility, determines caller location, identifies appropriate receiving agencies, and establishes simultaneous connections to multiple agencies. This multi-functional approach consolidates complexity into a single coordinating facility rather than requiring complex inter-agency communication infrastructure.
Solution Approach 2:
The special number call receiving facility acts as an intermediary that coordinates between the mobile calling unit and multiple receiving agencies. It receives the call, determines which agencies should be notified based on location and assistance type, and establishes connections to the appropriate agencies, thereby simplifying the coordination complexity.
3Measurement precision
If call routing is reevaluated during an active call, then routing accuracy improves, but call continuity may be disrupted
Solution Approach 1:
The system performs preliminary location determination and agency identification during the initial call setup phase. The location determining facility obtains caller location information and the special number call receiving facility identifies appropriate receiving agencies before the call is fully established, so that subsequent routing adjustments can be made smoothly without disrupting call continuity.
Solution Approach 2:
The system maintains continuous call connectivity while enabling dynamic routing adjustments. The mobile switching facility and special number call receiving facility work together to re route calls to additional or different agencies during the call without requiring call termination, ensuring continuous useful action (emergency assistance) throughout the call duration.

AI summary
A system for simultaneously routing a special number call from a mobile unit to a plurality of agencies includes (a) at least one of an unlicensed mobile access network and a radio access network communicating with the mobile unit; (b) a mobile switch coupled with at least one of the networks; (c) a call receiver coupled with the mobile switch; at least one of the call receiver and the mobile switch being coupled for communication with respective of the agencies; and (d) a locator coupled with at least one of the mobile switch and the call receiver. After receiving the special number call, the call receiver cooperates with at least one of the locator and the mobile switch to effect routing of the special number call to one or more included agency. Determination which agency is an included agency is made at the call receiver.
