LMR-BBR Diagnostic Backhaul for Large Event Logs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing land mobile radio (LMR) communication systems face challenges in efficiently logging and communicating large event logs, which are time-consuming and often require manual intervention, limiting their effectiveness in mission-critical scenarios.
Innovation Solution
A communications system integrating a land mobile radio (LMR) with a broadband backhaul radio (BBR) and a controller that stores diagnostic information and communicates it to a diagnostic server via BBR upon trigger events, using a higher data rate, enabling over-the-air (OTA) data retrieval and scrubbing of sensitive information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If diagnostic information is communicated via LMR, then communication simplicity is maintained, but transmission speed is slow and data transfer is time-consuming
Solution Approach 1:
The patent combines LMR and BBR into a unified communications system where the controller integrates both radio interfaces. The BBR is activated selectively to provide high-speed data transfer when needed, while the LMR maintains for voice communication, resolving the contradiction between speed and complexity through coordinated operation of both systems.
Solution Approach 2:
The controller acts as an intermediary that manages the interaction between LMR and BBR subsystems. It determines when to use each interface based on communication requirements, enabling fast data transfer via BBR while maintaining system simplicity through centralized control and coordination.
2Productivity
If manual retrieval of event logs is used, then system simplicity is maintained, but time consumption increases significantly
Solution Approach 1:
The system performs self-service by automatically detecting trigger events, retrieving diagnostic information from the LMR, and transmitting it via BBR without requiring manual intervention. The controller autonomously manages the entire diagnostic data retrieval process, significantly improving productivity while maintaining appropriate automation levels.
Solution Approach 2:
The system implements feedback mechanisms where the controller continuously monitors communication quality and trigger events. When diagnostic data needs to be retrieved, the system automatically initiates the process and receives feedback on transmission status, enabling efficient automated operation without excessive complexity.
3Reliability
If diagnostic information is transmitted without scrubbing, then transmission speed is maintained, but privacy and security are compromised
Solution Approach 1:
The controller performs preliminary scrubbing of diagnostic information to remove identifying details before transmission via BBR. This preliminary action ensures data security and privacy are maintained while the high-speed transmission channel is utilized for the sanitized data, minimizing overall processing time through efficient sequencing of operations.
Data Source
AI summary
A communications system may include a diagnostic server, a land mobile radio (LMR) having a first data rate, and a broadband backhaul radio (BBR) having a second data rate higher than the first data rate. The communications system may also include a controller configured to operate at least one application for communication via the LMR, store diagnostic information associated with the operation of the at least one application, and determine a trigger event. The controller may also be configured to communicate the diagnostic information to the diagnostic server via the BBR based upon the trigger event.
