Talkgroup Management via Network Activity Thresholds
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
First responders' talkgroup-enabled devices often unintentionally communicate on a different communication network while traveling, leading to unnecessary bandwidth usage on the current network.
Innovation Solution
A method and system that determine if a communication device is communicating with a talkgroup via a different network, assess the level of activity, and request confirmation to drop the device from the talkgroup when a threshold condition is met, thereby conserving bandwidth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a communication device communicates with a talkgroup via a different communication network while traveling, then the device maintains communication capability and accessibility, but unnecessary bandwidth is consumed on the current network
Solution Approach 1:
The system continuously monitors communication activity levels and network conditions, using this feedback to dynamically determine when to drop devices from talkgroups. The monitoring component tracks activity metrics and compares them against thresholds, providing continuous feedback that enables adaptive bandwidth management while maintaining communication reliability when needed.
Solution Approach 2:
The system dynamically adjusts talkgroup membership based on real-time conditions rather than maintaining static assignments. Devices are automatically added or removed from talkgroups depending on current activity levels and network conditions, allowing the system to adapt to changing communication needs and minimize unnecessary bandwidth consumption.
2Loss of energy
If the system monitors and manages talkgroup communication activity, then bandwidth efficiency is improved, but system complexity increases
Solution Approach 1:
The system is divided into distinct functional components: a monitoring component that tracks communication activity, a determination component that analyzes activity levels against thresholds, and a dropping component that executes removal decisions. This segmentation allows each component to perform its specific function efficiently, managing complexity through modular design while achieving bandwidth optimization.
3Loss of energy
If a device is automatically dropped from a talkgroup to conserve bandwidth, then bandwidth wastage is reduced, but communication reliability may be compromised
Solution Approach 1:
The system establishes predetermined activity thresholds and decision criteria in advance. Before dropping a device, the system has already monitored activity levels and determined that the device meets the criteria for removal. This preliminary assessment ensures that dropping decisions are made only when appropriate, maintaining reliability for active communications while conserving bandwidth for inactive ones.

AI summary
A device, system and method for managing talkgroups is provided. A computing device determines that a communication device is communicating with a talkgroup via a first communication network, the talkgroup dominated by other communication devices communicating on one or more second communication networks different from the first communication network. The computing device determines a level of activity of the communication device in the talkgroup via the first communication network. When the level of activity meets a threshold condition, the computing device: requests a confirmation from the communication device to cease communication with the talkgroup; and when the confirmation is received, drops the communication device from the talkgroup.
