Radio Terminal Auto-Reply Status Reporting via Mobile Network
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional radio communication systems lack the ability for radio terminals to automatically reply their operation status to consoles, leading to communication failures and operational issues when terminals are off, out of range, or not on duty, resulting in incomplete status updates and reduced system effectiveness.
Innovation Solution
The system includes a radio terminal with a processing unit equipped with an auto-reply module that automatically transmits status information via a mobile communication system, including power on/off, duty, area, and monitor reply programs, allowing instantaneous status updates and enabling receipt of control commands through RF or mobile communication systems, along with OTAP control commands for remote operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If radio terminals use manual response method to send Ack or text/voice messages, then the system structure remains simple, but the console cannot obtain actual status of radio terminals and communication fails when terminals are off or out of range
Solution Approach 1:
The radio terminal automatically transmits status information (power on/off, on duty/off duty, area location, monitor status) to the console without requiring manual operation. The processing unit automatically generates and sends status reports when the terminal's operational state changes, enabling the system to self-report its condition and eliminating the need for manual acknowledgment in many scenarios.
Solution Approach 2:
The patent introduces a dual communication path: RF communication for immediate local communication and mobile communication system (GSM/GPRS) as an intermediary for remote communication. When the terminal is out of RF range or off, the mobile communication system serves as an intermediary to transmit status information and control commands between the terminal and console, ensuring continuous status reporting regardless of terminal state.
2Loss of information
If radio terminals automatically transmit status information through mobile communication system, then the console can obtain actual status continuously, but the device complexity and energy consumption increase
Solution Approach 1:
Instead of continuous transmission, the terminal transmits status information periodically or event-driven. The processing unit detects changes in operational status (power state, duty status, area location, monitor status) and triggers status transmission only when changes occur, rather than continuously reporting. This periodic/event-driven approach reduces energy consumption while ensuring the console receives complete status information.
Solution Approach 2:
The system dynamically selects communication methods based on terminal state and environmental conditions. When the terminal is within RF range and active, it uses low-power RF communication. When off or out of range, it switches to mobile communication system. This dynamic adaptation optimizes energy consumption while maintaining complete status information transmission.
3Adaptability or versatility
If radio terminals are equipped with auto-reply module and dual communication capability, then the system can maintain communication when terminals are off or out of range, but the device complexity increases
Solution Approach 1:
The radio terminal is designed with multi-functionality, incorporating both RF receiver module for local communication and mobile transceiver module for remote communication. The processing unit handles multiple functions: receiving text/voice messages, generating Ack messages, detecting status changes, and selecting appropriate communication paths. This universal design enables the terminal to adapt to various communication scenarios (within range/out of range, on/off duty) without requiring separate dedicated devices for each function.

AI summary
A radio communication system having functions of replying status information and remote control, includes a console and a plurality of radio terminals, wherein each of the radio terminal is capable of transmitting corresponding Ack message about an operation status thereof to the console over a mobile communication system, if the operation status is changed. After receiving the Ack message, the console automatically or manually transmits corresponding message or a control command to the radio terminal to change the operation status of the radio terminal. Furthermore, when transmitting dispatch message, the console is capable of storing the dispatch message simultaneously in a server so as to allow the radio terminal to access the server and retrieve the stored dispatch message.
