Dynamic Special Number Call Coupling via Network Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing special number call systems lack the ability to dynamically re-couple a caller with function-focused answering units without breaking the connection, requiring callers to redial or manually re-route calls as conditions change.
Innovation Solution
A system and method that utilize an unlicensed mobile access network, radio access network, and public switched telephone network, coupled with a network switching facility and a special number call receiving facility, to dynamically re-couple special number calls with function-focused answering units based on location and service requirements, allowing continuous communication without the need for callers to redial.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the system uses static call routing to connect special number calls with function-focused answering units, then the initial call connection is established, but the system cannot adapt to changing locations, conditions, or services sought during the call
Solution Approach 1:
The patent implements dynamic call routing that allows the system to re-couple a special number call with different function-focused answering units during the call based on changing conditions. The network switching facility monitors call parameters, location information, and service requirements, and can dynamically redirect the call to the most appropriate answering unit without requiring the caller to hang up and redial, thus making the routing system adaptive rather than static
Solution Approach 2:
The network switching facility is designed to handle multiple types of special number calls (emergency 9-1-1, non-emergency N-1-1, commercial services) and can route them to various function-focused entities (PSAPs, utility companies, commercial services). This multi-functional capability allows a single routing system to serve diverse call types and destinations, improving adaptability across different service domains
2Ease of operation
If the system implements dynamic re-coupling of calls during active communication, then the caller can be connected to the most appropriate function-focused entity without redialing, but the call connection may be disrupted or broken
Solution Approach 1:
The network switching facility acts as an intermediary between the caller and function-focused answering units. It maintains the call connection by managing the switching and re-coupling processes in the background without requiring the caller to take action. The intermediary facility ensures seamless transitions by controlling the re-routing at the network level, preserving call continuity while enabling dynamic re-coupling
Solution Approach 2:
The system performs preliminary evaluation of call parameters, location information, and service requirements before executing re-coupling decisions. By assessing whether re-coupling is necessary and identifying the appropriate target answering unit in advance, the system can prepare the re-routing path beforehand, minimizing disruption to the active call connection and ensuring smooth transitions
3Loss of time
If the system requires manual intervention or caller action to re-route calls to different function-focused entities, then the routing logic can be simple, but the caller must hang up and redial, causing loss of time and disruption
Solution Approach 1:
The system implements automatic call re-coupling that evaluates call parameters, location information, and service requirements autonomously without requiring caller intervention. The network switching facility independently determines when re-coupling is necessary and executes the re-routing to the appropriate function-focused answering unit, allowing the system to serve itself in managing call connections and eliminating the need for caller action to re-establish connections

AI summary
A system for dynamically coupling a special number call from a calling unit with at least one function-focused answerer includes: (a) at least one of an unlicensed mobile access network, a radio access network, and a public switched telephone network configured and situated for communicative coupling with the calling unit; (b) at least one network switch coupled with at least one of the networks; and (c) a special number call receiver coupled with the network switch. At least one of the special number call receiver and the network switch is configured for communicative coupling of the special number call with the at least one function-focused answerer unit. After receiving the special number call, the special number call receiver dynamically couples the special number call to an included function-focused answerer. Determining which function-focused answerer is an included function-focused answerer is made at the special number call receiver.
