Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Public-safety responders face inefficiencies in communication due to the lack of methods and systems for seamlessly patching direct-mode talkgroups among dual-watch mobile radios, which limits the immediacy and efficacy of communication during incidents.
Innovation Solution
A mobile radio system with dual receivers that detects patch events to initiate or join talkgroup sessions across multiple radio channels, allowing for efficient communication by transmitting and receiving audio across associated talkgroups.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If mobile radios use traditional single-talkgroup communication methods, then device complexity is reduced, but communication efficiency and immediacy deteriorate
Solution Approach 1:
The mobile radio device is divided into multiple independent receiver units (first receiver and second receiver), each capable of monitoring separate talkgroups simultaneously. This segmentation allows the device to handle multiple communication channels in parallel, improving communication efficiency without requiring a complete system overhaul.
Solution Approach 2:
The mobile radio device is designed with multi-functionality to monitor and participate in multiple talkgroups simultaneously through direct-mode communication. The device can switch between monitoring different talkgroups and establishing patch connections, making it adaptable to various communication scenarios and improving overall productivity.
2Loss of time
If mobile radios implement seamless patching across multiple talkgroups, then communication immediacy is improved, but system complexity increases
Solution Approach 1:
The mobile radio device pre-establishes monitoring of multiple talkgroups using dual receivers before patching is needed. By having receivers already tuned and ready on different talkgroups, the system eliminates the time required to switch frequencies or establish new connections when patching events occur,从而实现 immediate communication.
Solution Approach 2:
The patching message serves as an intermediary mechanism that coordinates between different talkgroups. When a patching event occurs, the system uses structured patching messages to invite members from one talkgroup to join another, facilitating seamless communication without requiring complex direct switching infrastructure.
3Adaptability or versatility
If dual-watch mobile radios monitor multiple radio channels simultaneously, then communication versatility is improved, but energy consumption increases
Solution Approach 1:
The dual receivers continuously monitor their respective talkgroups without interruption, ensuring that communication opportunities are never missed. This continuous monitoring across multiple channels provides versatility and adaptability, allowing the device to immediately respond to patching events or emergency communications on any monitored talkgroup.

AI summary
Disclosed herein are methods and systems for patching direct-mode talkgroups among dual-watch mobile radios. A mobile radio has first and second receivers, and is in a first talkgroup having a first channel. The mobile radio resides the first receiver on the first channel, and detects either a first patch event or a second patch event. The first patch event is an instruction for a first-channel session. The second patch event is an invitation for a second-channel session. Upon detecting the first patch event, the mobile radio transmits an invitation on the first channel and also on one or more other channels respectively associated with one or more other talkgroups, directing all recipients to the first channel. If the mobile radio detects the second patch event, the mobile radio resides the second receiver on the second channel.
