Public Safety Incident Information Exchange Controller
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Public safety forces face challenges in responding effectively to ongoing incidents due to incomplete or delayed information from remote sources, and obtaining information from witnesses and injured persons is often hindered by their identification and willingness to share, which is typically done after the situation has stabilized.
Innovation Solution
A communication system and method utilizing a controller to identify and categorize portable communication devices within a region of interest, assigning them to trusted or non-trusted groups based on subscriber profiles and operating characteristics, enabling secure information exchange during public safety incidents, such as hostage situations, to facilitate more effective responses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If information is obtained from remote dispatch centers, then public safety forces can receive incident information, but the information may not reflect the ground situation accurately and may be delayed
Solution Approach 1:
The system proactively identifies and categorizes portable communication devices within the region of interest before public safety forces arrive at the incident scene. By pre-establishing trusted groups of devices and preparing information gathering mechanisms in advance, the system eliminates delays that would occur if information collection started after arrival. This preliminary action ensures both timely and accurate ground situation information is available immediately when forces reach the scene.
2Loss of information
If information is obtained from witnesses and injured persons, then incident-specific information can be gathered, but this is only possible after the situation has stabilized and they are identified
Solution Approach 1:
The system identifies and categorizes portable communication devices as potential witnesses or injured persons before the situation stabilizes. By using location information and operating characteristics to create trusted groups in advance, the system is ready to immediately gather information from these identified individuals as soon as they are accessible, eliminating the delay of waiting for situation stabilization and manual identification.
Solution Approach 2:
The system continuously monitors location information and operating characteristics of portable communication devices, providing real-time feedback about device status and location. This feedback mechanism allows the system to dynamically update which devices are potential witnesses or injured persons, ensuring that information can be gathered from the most relevant sources at the optimal time without waiting for situation stabilization.
3Loss of information
If all portable communication devices in the region are monitored, then complete information can be gathered, but the system complexity and processing load increase
Solution Approach 1:
The system segments portable communication devices into distinct trusted and non-trusted groups based on location information and operating characteristics. This segmentation allows the system to focus information gathering efforts on the trusted group, which contains devices most likely to provide relevant incident information. By dividing the monitoring scope into segments rather than uniformly monitoring all devices, the system reduces processing load and complexity while maintaining comprehensive coverage of relevant information sources.
Solution Approach 2:
The system applies different monitoring and information gathering strategies to different device groups based on their specific characteristics. Trusted group devices receive prioritized attention with enhanced information gathering, while non-trusted devices receive minimal or no monitoring. This local quality approach ensures that system resources are concentrated where they are most needed for accurate incident information collection, reducing overall system complexity while maintaining information coverage.
Data Source
AI summary
A method to operate a controller for exchanging information corresponding to a public safety incident is provided. In operation, the controller transmits a request to communication networks to send location information for portable communication devices operating in a region of interest. The controller, based on the location information received from the communication networks for the portable communication devices, selects a subset of portable communication devices. The controller assigns each device in the subset to a trusted group of devices or a non-trusted group of devices based on the respective subscriber profile and operating characteristics of the portable communication devices. The controller then establishes a connection with high priority portable communication devices in the trusted group via a public safety communication network to exchange information corresponding to the incident.
