Automatic Talk Group Creation in Digital Radio Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In digital radio communication systems, emergency situations are delayed due to the manual process of creating talk groups and assigning emergency service units, which can lead to inefficiencies in communication during critical events.
Innovation Solution
A method for automatically creating a talk group in digital radio communication systems, where a mobile station can initiate an emergency message with its ID and location, and nearby units respond, allowing the system to dynamically form a talk group with the closest emergency service units, either with or without infrastructure, by calculating distances and selecting units within predefined areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If manual process of creating talk group and assigning emergency service units is used, then dispatcher control and coordination are maintained, but time delay occurs in emergency situations
Solution Approach 1:
The system pre-positions emergency service units and their communication capabilities before emergencies occur. When an emergency message is sent, the system automatically activates and assembles the pre-identified talk group members based on their proximity to the incident location, eliminating the need for manual dispatcher coordination during critical timeframes.
Solution Approach 2:
The mobile station and system automatically perform the talk group creation and member assignment functions that would traditionally require dispatcher intervention. The system self-manages the identification of nearby emergency service units, calculates their proximity to the incident, and autonomously assembles the appropriate talk group without external human control.
2Productivity
If automatic creation of talk group is implemented, then response time is reduced, but system complexity increases
Solution Approach 1:
The mobile stations and system components are designed with multi-functionality, serving both routine communication operations and emergency response functions. The same infrastructure used for normal talk group operations is leveraged for automatic emergency talk group creation, avoiding the need for separate dedicated systems and reducing overall complexity.
Solution Approach 2:
The system continuously monitors the locations of mobile stations and emergency service units, maintaining real-time spatial awareness. When an emergency message is received, this feedback information about unit positions is immediately processed to automatically identify and assemble the nearest available units into a talk group, enabling rapid response without complex manual coordination.
3Reliability
If dispatcher manually coordinates emergency dispatch, then communication control is maintained, but additional information exchange is required causing delay
Solution Approach 1:
The system introduces an automated intermediary process that handles the information exchange and coordination tasks between the emergency message sender and the emergency service units. This automated mediator rapidly processes location data, identifies appropriate units, and establishes communication channels, maintaining control while eliminating the time-consuming manual information exchange required by human dispatchers.

AI summary
A method of automatic creation of a talk group in a wireless radio communication system comprising a plurality of mobile stations, said method comprising the steps of: transmitting by a first mobile station an emergency message containing at least its ID and localization data; transmitting by other mobile stations their IDs and localization data in response to said emergency message; creating said talk group by selecting those mobile stations which transmitted their IDs and localization data.
