Proxy Gateway Scanning for First Responder Communication Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Scanning multiple communication systems by mobile devices, such as those used by first responders, is time-consuming and prone to delays, often resulting in missed calls across different systems.
Innovation Solution
A system featuring a gateway device that acts as a proxy for mobile devices, allowing them to outsource scanning functionality to the gateway for one communication system type, freeing up resources to scan another type, with priority given to calls from the first system, ensuring that incoming calls are answered by interrupting existing scans or calls on the second system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mobile devices scan multiple communication systems simultaneously, then call detection capability is improved, but device resources are overwhelmed and scanning efficiency deteriorates
Solution Approach 1:
The gateway device serves as an intermediary between mobile devices and communication systems. It receives scan lists from mobile devices, performs the actual scanning of first communication systems, and returns results to mobile devices. This mediator approach allows mobile devices to outsource scanning tasks, enabling them to maintain call detection capability while avoiding resource exhaustion from simultaneous multi-system scanning.
2Use of energy by moving object
If mobile devices outsource scanning to gateway, then resource usage is reduced, but device complexity increases
Solution Approach 1:
The gateway device is introduced as a centralized intermediary that handles the complexity of multi-system scanning. Mobile devices maintain simplified functionality by communicating scan requirements and receiving results, while the gateway assumes the complex tasks of coordinating multiple communication systems, managing scan lists, and processing results. This distribution of complexity reduces individual device resource usage while managing overall system complexity through centralized control.

AI summary
A device, method and system for scanning communication systems of different types is provided. A mobile device comprises: first and second transceivers to communicate first and second communication systems of different types; a memory storing first and second scan lists for scanning first and second channels on the first and second communication systems; and a controller configured to: communicate, using the first transceiver, an indication of the first and second scan lists to a gateway device configured as a proxy for the mobile device to communicate with the first communication systems; receive, using the first transceiver, from the gateway device, a reply indicating that the gateway device is capable of scanning the first communication systems using the first scan list, but is not capable of scanning the second communication systems; and control the second transceiver to scan the one or more second communication systems using the second scan list.
