NSI Emergency Call Parameters for Location-Aware 911 Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Non-service initiated (NSI) emergency calls in wireless communication networks lack essential subscriber and location information, leading to inefficient emergency response and vulnerability to denial of service attacks due to the absence of a callback number and location data.
Innovation Solution
Network equipment generates and transmits an NSI parameter message containing location and subscriber information directly to a public safety answering point (PSAP) during an NSI emergency call, even without home or roaming network coverage, using a processor and memory to facilitate this process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If NSI emergency calls are allowed without service agreement verification, then emergency service accessibility is improved, but network security and service quality deteriorate due to lack of subscriber information
Solution Approach 1:
The patent applies preliminary action by requiring the device to determine its location and generate an NSI parameter message with location information before the emergency call is actually placed. This advance preparation ensures that critical information is ready when the emergency call is initiated, resolving the contradiction by having subscriber information prepared in advance without requiring a service agreement at the moment of calling
Solution Approach 2:
The patent introduces an intermediary mechanism by using location information as a substitute for traditional subscriber information. Instead of requiring callback numbers and service agreement details, the system uses GPS or network-based location data as an intermediary to identify and contact the appropriate PSAP, thereby maintaining network security while enabling emergency accessibility
2Productivity
If NSI parameter messages with location data are transmitted, then emergency response efficiency is improved, but device complexity and processing requirements increase
Solution Approach 1:
The patent applies the taking out principle by extracting only the essential location information from the device and transmitting it separately as an NSI parameter message, rather than requiring the transmission of complete subscriber profiles or complex service agreement data. This extraction of minimal necessary information improves emergency response efficiency while keeping device complexity manageable
Solution Approach 2:
The patent applies universality by designing the NSI parameter message to serve multiple functions: it provides location information for PSAP routing, enables emergency service delivery, and maintains network security protocols. This multi-functional approach consolidates multiple requirements into a single message structure, reducing overall device complexity while improving emergency response efficiency

AI summary
Respective implementations facilitating non-service initiated (NSI) 911 device parameters are provided. A method can include detecting, by a system comprising a processor, an initialization of an emergency call by the system, the emergency call using a first communication network that is distinct from any second communication networks that the system is registered to use; generating, by the system in response to the detecting, a non-service initiated parameter message comprising data indicative of a location of the system; and initiating, by the system, the emergency call using the first communication network, the initiating comprising transmitting the non-service initiated parameter message to network equipment of the first communication network.
