MTC-IWF Triggering Message Control for System Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication systems for machine-type communications (MTC) do not effectively monitor and manage frequent triggering of specific MTC devices, leading to reduced operation guaranteed periods and potential system malfunctions due to increased battery consumption and network congestion.
Innovation Solution
A control unit within the MTC-IWF monitors triggering messages based on identifiers for specific MTC devices or groups, controlling the transmission of triggering messages to prevent excessive triggering by discarding or buffering low-priority messages, thereby maintaining system operation and preventing malfunctions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If triggering messages are transmitted frequently to activate MTC devices, then communication activation capability is improved, but battery consumption increases and operation guaranteed period is reduced
Solution Approach 1:
The MTC-IWF performs preliminary monitoring of triggering message frequencies and identifies abnormal triggering patterns before they cause excessive battery consumption. By detecting abnormal triggering in advance and controlling message transmission proactively, the system prevents harmful effects while maintaining communication activation capability.
Solution Approach 2:
The system implements feedback mechanisms where the MTC-IWF monitors triggering message frequencies, compares them against thresholds, and adjusts transmission control based on monitored results. This closed-loop control enables the system to maintain productivity while preventing excessive energy consumption through dynamic adaptation.
2Speed
If triggering messages are transmitted frequently, then device activation response speed is improved, but network congestion occurs and system reliability deteriorates
Solution Approach 1:
The MTC-IWF dynamically adjusts triggering message transmission control based on real-time monitoring of message frequencies and system state. The control mechanism transitions between different operational states (normal transmission, rate limiting, blocking) based on monitored conditions, enabling the system to maintain fast activation response while preventing network congestion and preserving reliability.
3Adaptability or versatility
If triggering messages are transmitted without monitoring, then communication flexibility is improved, but abnormal triggering causes operation stops and system malfunction
Solution Approach 1:
The MTC-IWF acts as an intermediary between the triggering message source and the target device, inserting monitoring and control functions into the communication path. This intermediary role enables the system to maintain communication flexibility for legitimate triggering while filtering out abnormal triggering that would cause system malfunctions or operation stops.
