Radio Device Temporary Group Formation Using Position Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In radio communication systems where multiple devices are temporarily grouped, challenges arise when some members are remote from the site or leave the location, leading to inefficient grouping and complex operations for canceling these groups.
Innovation Solution
A radio communication system with a first device capable of promoting temporary group formation and second devices that calculate position information and participate based on proximity, allowing for dynamic grouping and automatic cancellation of remote devices without complex operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If radio devices are grouped temporarily without position verification, then group formation is simple and quick, but remote devices are incorrectly included in the group
Solution Approach 1:
The system performs preliminary position verification by calculating distances between radio devices before allowing group formation. The position information transmission controller transmits position information and the distance calculator computes distances to ensure all devices are within predetermined distance thresholds before grouping occurs, preventing remote devices from being incorrectly included.
Solution Approach 2:
The patent replaces manual group management operations with automated position-based verification. Instead of relying on manual device selection or complex operational procedures, the system automatically calculates distances between devices using position information and controls group formation based on these calculated distances, simplifying the process while ensuring accuracy.
2Reliability
If position verification is performed before group formation, then only proximal devices are included in the group, but the grouping process becomes more complex
Solution Approach 1:
Each radio device autonomously calculates its own position information and automatically determines whether to participate in group formation based on distance calculations. The temporary group participation controller at each device evaluates the distance to the first radio device and independently decides on participation, eliminating the need for complex centralized control or manual verification procedures.
Solution Approach 2:
The system uses position information as a dynamic parameter to control group formation. By transmitting and comparing position coordinates and calculating distances between devices, the system automatically adjusts group composition based on spatial parameters, ensuring that only devices within predetermined distance thresholds are included without requiring complex procedural interventions.
3Adaptability or versatility
If manual operations are required to cancel groups when members leave, then group management is flexible, but operations become complicated and time-consuming
Solution Approach 1:
The system continuously monitors position information of devices in the temporary group. When a device moves beyond the predetermined distance threshold from the first radio device, the distance calculator detects this change and the temporary group participation controller automatically removes the device from the group or cancels the group formation, providing real-time feedback-based automatic management without requiring manual intervention.
Solution Approach 2:
The group composition is made dynamic and automatically adjusts based on real-time position changes. Instead of requiring manual reconfiguration when members leave or move away, the system continuously evaluates distance parameters and automatically updates group membership or cancels grouping when devices exceed distance thresholds, making the system adaptive to movement without complex operational procedures.

AI summary
A first radio device promotes formation of a temporary group. A second radio device responds to the promotion of the formation of the temporary group. The first radio device includes: a first position information calculator that calculates position information of the first radio device; and a position information transmission controller that controls to transmit the position information of the first radio device to the second radio device at a time of promoting the formation of the temporary group. The second radio device includes: a second position information calculator that calculates position information of the second radio device; a distance calculator that calculates a distance between the first and second radio devices; and a temporary group participation controller that controls to participate in the temporary group when the distance between the first and second radio devices is within a predetermined distance.
