Radio Control Service Automatic Participant Addition

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

In IPICS systems, manually adding new participants to existing talk groups is time-consuming and disruptive, as it requires participants to determine how to communicate with the operator and wait for response, which can be inconvenient and delay their participation in group calls.

Innovation Solution

Implementing a Radio Control Service (RCS) functionality that automatically adds new communication devices to established dynamic group calls upon detection of call alerts, either without authentication or after authenticating the devices, allowing them to join the talk group quickly and efficiently.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual addition of participants is used, then operator control is maintained, but time consumption and operational disruption increase

Engineering Contradiction:

Improveease of adding participantsVSAvoidtime to add participant

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The system pre-configures talk groups with authorized participant identifiers and permissions before actual group calls occur. When a group call is initiated, participants are automatically added based on these pre-established rules, eliminating the need for real-time manual addition operations.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system enables participants to automatically join talk groups by sending service requests that are processed according to pre-configured authorization rules. The participant initiates the joining process independently, and the system automatically validates and completes the addition without requiring operator intervention.

Inventive Principle:

Principle #25Self-service

2Productivity

If automatic addition is implemented, then participant joining speed improves, but system complexity and authentication requirements increase

Engineering Contradiction:

Improveparticipant joining speedVSAvoidsystem complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

Authorization rules and participant identifiers are pre-configured in the system before group calls occur. This preliminary setup creates a database of authorized participants and their associated talk groups, enabling rapid automatic addition during actual operations without complex real-time decision-making.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system implements a service request mechanism where participants send joining requests and receive automated responses based on their authorization status. The system checks the pre-configured rules, determines eligibility, and provides feedback by either automatically adding the participant or notifying them of denial, creating a closed-loop control system.

Inventive Principle:

Principle #23Feedback

AI summary

In one embodiment, a method includes initiating a dynamic group call, detecting a call alert, and identifying a user system responsible for the call alert. The dynamic group call includes at least one original participant, and is initiated such that an ability to automatically add at least one new participant to the dynamic group call is enabled. Identifying the user system includes obtaining an indicator from the call alert. The indicator is associated with the user system. Finally, the method includes automatically adding the user system to the dynamic group call.
