Emergency Range Tracking Authorization Without Prior Pairing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile devices require preexisting interoperability authorization (e.g., bonding, registration, or pairing) for location tracking, which hinders emergency response in situations where such authorizations are unavailable or impractical.
Innovation Solution
Mobile devices perform single-sided authorization by transmitting device addresses and credentials to enable secure connection with tracking devices for ranging information exchange without prior interoperability, allowing emergency responders to locate the device even in challenging environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If preexisting interoperability authorization (bonding, registration, or pairing) is required for location tracking, then device security and authorization control are improved, but emergency response capability and location tracking availability deteriorate
Solution Approach 1:
The system performs preliminary authorization setup during normal operation where the mobile device stores authorization information for designated tracking devices. When an emergency occurs, this pre-established authorization enables immediate tracking without requiring real-time pairing or bonding, thus resolving the contradiction between security control and emergency response capability
Solution Approach 2:
The patent introduces an intermediary authorization mechanism that acts as a mediator between the mobile device and tracking devices. The authorization information serves as a pre-established trust relationship that allows tracking devices to connect to mobile devices during emergencies without requiring traditional interoperability authorization, thus enabling emergency tracking while maintaining security
2Reliability
If preexisting device pairing is required for ranging information exchange, then connection security is improved, but response time and emergency location tracking efficiency deteriorate
Solution Approach 1:
The system establishes authorization relationships in advance during normal operation, storing authorization information that includes device addresses and credentials. During emergencies, this pre-configured authorization eliminates the time-consuming pairing process while maintaining secure connections through the use of pre-validated credentials
3Device complexity
If traditional positioning systems are used in challenging environments, then system simplicity is maintained, but location accuracy and tracking reliability deteriorate
Solution Approach 1:
The patent introduces ranging devices as intermediary components that facilitate location tracking in challenging environments where traditional GPS positioning fails. These devices establish direct communication with mobile devices using pre-configured authorization, enabling accurate distance and location measurement through proximity-based ranging without relying on satellite positioning systems

AI summary
In one example, a mobile device comprises a memory that stores instructions, and one or more processors that execute the instructions to detect an indication of an emergency, responsive to detecting the indication of the emergency, transmit, to a tracking device, authorization information including at least one or more device addresses to cause the tracking device to generate an authorized request for ranging information based on the authorization information, the ranging information including an indication of a distance between the mobile device and the tracking device, receive the authorized request for ranging information from the tracking device, responsive to receiving the authorized request, establish a secure connection with the tracking device, and transmit the ranging information to the tracking device through a secure connection with the tracking device.
