Radio Gateway Device Dynamic Mode Switching for Mixed Message Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radiocommunications gateway devices are limited in functionality, primarily designed for group voice communications and cannot handle other forms of messages, such as written or data transfers, which restricts their utility in professional settings like police patrols where accessing databases or sending SMS messages is necessary.
Innovation Solution
A gateway device with multiple operating modes, including active, suspended, and inactive, controlled by a controller that allows for the processing and transmission of various message types, including non-voice messages, through distinct transmitters and interfaces, enabling communication configurations for different message natures and priorities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the gateway device is designed for group voice communications only, then the device complexity is reduced and ease of manufacture is improved, but the adaptability and versatility are worsened
Solution Approach 1:
The gateway device is designed to handle multiple types of messages including voice messages, written messages, and data transfers through a single unified interface (115). The controller (215) is configured to process different message types by selecting appropriate transmission modes, enabling the gateway to perform group communications, private communications, and database access functions without requiring separate dedicated devices for each function.
2Adaptability or versatility
If the gateway device handles multiple message types, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The gateway device employs dynamic mode selection where the controller (215) can switch between different transmission modes (group voice, private voice, written messages, data transfers) based on the type of message received. This dynamic adaptability allows the same hardware infrastructure to be reconfigured for different communication purposes, reducing the need for multiple dedicated hardware components and simplifying manufacturing while maintaining versatility.
3Adaptability or versatility
If the interface is used as a terminal for non-group communications, then the versatility is improved, but transmission conflicts arise without priority management
Solution Approach 1:
The controller (215) implements a priority management system that monitors incoming message types and determines the appropriate transmission mode by evaluating message characteristics. When multiple types of messages are present, the controller applies predefined priority rules to select which messages to transmit first, ensuring that critical communications (such as emergency alerts or high-priority data transfers) are handled appropriately while managing resource allocation effectively.

AI summary
The present invention relates to a radio communications gateway device (200) for retransmitting messages of different forms between a first radio communications network (202) and a second radio communications network (204), said gateway device (200, 300) including: a first transmitter (214) capable of processing the radio communications of the first network (202) according to a first coding scheme, a second transmitter (216) capable of processing the radio communications of the second network (214) according to a second coding scheme, and a switch (201) which, when the gateway device is activated, connects the first and second transmitters (214, 216) to retransmit voice messages from a group communication processed by one of said transmitters (214, 216) to the other of said transmitters (214, 216), characterized in that said switch includes a controller (215) for automatically implementing: the gateway device in active mode upon reception of a voice message of a group communication; the gateway device in suspended mode by suspending the switch (201) so that said first and second transmitters (214, 216) process independently of one another voice or non-voice messages between the gateway device and one of the two radio communication networks, respectively, the suspended mode being activated when signaling data of the messages of different forms indicate a change in communication other than a group voice communication.
