Mobile Station Location Association for Audio Incidents
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing location estimation techniques for mobile stations often rely on stale database data, leading to an unacceptable number of false positives, particularly in law enforcement applications where accurate location information is critical, such as in identifying individuals involved in audio incidents like gunshots.
Innovation Solution
A system and method that detects an audio incident and initiates mobile-terminated location requests to determine the current location of nearby mobile stations using Wireless Location Signatures, reducing false positives by obtaining location data directly from the triggering process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If database-based location estimation techniques are used, then location data can be obtained, but the location data becomes stale and produces false positives
Solution Approach 1:
The system pre-establishes audio incident detection capabilities and location request mechanisms before incidents occur. Audio sensors continuously monitor for incidents, and location request protocols are pre-configured to immediately query mobile stations when incidents are detected, ensuring current location data is obtained rather than relying on stale database entries
Solution Approach 2:
The system implements a feedback loop where audio incident detection triggers immediate location requests to mobile stations, which then provide real-time location data back to the system. This closed-loop feedback ensures location information is continuously updated and reflects current positions, eliminating the staleness problem of database-based approaches
2Measurement precision
If mobile-terminated location requests are initiated, then current location data is obtained, but system complexity increases
Solution Approach 1:
The system leverages existing multi-functional mobile station capabilities to handle location requests. Mobile stations that already possess GPS and wireless communication functionalities are utilized to provide location data, eliminating the need for separate dedicated location tracking devices and reducing overall system complexity
Solution Approach 2:
Mobile stations autonomously respond to location requests by providing their own GPS and location data without requiring external location determination equipment. The mobile stations self-serve the location information needs of the system, simplifying the architecture by eliminating complex external location determination infrastructure

AI summary
Systems and methods are disclosed that initiate mobile-terminated location requests in response to receiving an indication that an audio incident occurred at a given location. The mobile-terminated location requests are initiated for one or more mobile stations within a cell of a wireless network that is known to provide wireless service coverage to a geographic area that comprises the location of the audio incident. In response to the mobile-terminated location request, an estimate of the mobile station's current location is received. Based on the estimated current location of the mobile station relative to the location of the audio incident, the illustrative systems and methods may generate an association between the mobile station and the audio incident. When an association is generated, it is transmitted for possible further processing.
