Temporary Dialable Number for Emergency Call Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile communication devices with non-dialable numbers, such as those embedded in vehicles or industrial control systems, pose challenges for emergency calling as they cannot be directly routed to public safety answering points (PSAPs), preventing callback connections in case of link failures.
Innovation Solution
A system and method that associate a temporary dialable number with non-dialable mobile stations, routing emergency calls through a network node to establish a communication link with the nearest PSAP, using a server to create data entries and delegate link establishment to signaling nodes like CSCF platforms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a mobile station with a non-dialable number initiates an emergency call, then the emergency call can be received by the network, but the public safety answering point cannot establish a callback connection to the mobile station
Solution Approach 1:
The patent introduces a temporary dialable number as an intermediary between the non-dialable mobile station number and the PSAP callback system. When an emergency call is received from a mobile station with a non-dialable number, the network assigns a temporary dialable number that the PSAP can use to establish callback connections. This intermediary number resolves the contradiction by enabling callback functionality without requiring the original non-dialable number to be routable.
2Adaptability or versatility
If emergency calls from mobile stations with non-dialable numbers are supported, then regulatory compliance is achieved, but the network requires additional complexity to route and manage these calls
Solution Approach 1:
The patent applies preliminary action by pre-assigning temporary dialable numbers to mobile stations with non-dialable numbers before emergency calls are initiated. The network maintains a pool of temporary numbers and assigns them in advance, so that when an emergency call is received, the routing path is already established. This reduces the complexity of real-time routing decisions and simplifies the handling of emergency calls from non-dialable numbers.
3Adaptability or versatility
If mobile stations with non-dialable numbers are used in vehicles and industrial control systems, then device functionality is improved, but emergency calling capability is compromised
Solution Approach 1:
The temporary dialable number serves as a mediator that enables reliable emergency call delivery for mobile stations with non-dialable numbers used in vehicles and industrial control systems. The intermediary number provides a routable path for both incoming emergency calls and outgoing callback connections, ensuring that these specialized devices maintain emergency calling capability despite their non-dialable number configuration.

AI summary
A system for connecting a mobile emergency call to a public safety answering point (PSAP). The system comprises a processor, a non-transitory memory, and an application stored in the memory. When executed by the processor, the application receives an emergency call from a mobile station, wherein the mobile station is associated with a non-dialable number, in response to receiving the emergency call from the mobile station, associates a temporary dialable number to the mobile station, and promotes establishing a communication link between the mobile station and a public safety answering point and providing the temporary dialable number to the public safety answering point.
