Wireless Gateway Load Control via Signal End Date Thresholding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Data concentration gateways in wireless communication networks face limitations in processing multiple signals simultaneously due to the number of demodulators they possess, leading to potential overload situations, which existing technologies fail to effectively manage.
Innovation Solution
A method for controlling the load of data concentration gateways by receiving data signals, determining their communication start and end dates, comparing the number of signals to a threshold, and emitting an alarm when the load exceeds the number of demodulators, ensuring that the gateway does not process more signals than it can handle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the gateway increases its coverage and reception capacity to handle more communication modules, then the coverage area and number of connected devices are improved, but the gateway becomes overloaded when the number of simultaneous signals exceeds the number of demodulators
Solution Approach 1:
The gateway performs preliminary actions by calculating communication end dates for all received signals and sorting them in ascending order. This preprocessing allows the gateway to proactively identify potential overload conditions before they occur, enabling timely rejection of excess signals to maintain reliable processing of within-capacity signals.
Solution Approach 2:
The invention implements a feedback mechanism where the gateway continuously monitors its demodulator capacity by comparing the number of active signal processing tasks against available demodulators. When the number of simultaneous signals exceeds the number of demodulators, the gateway provides feedback by rejecting additional signals and can dynamically adjust its acceptance criteria based on current load conditions.
2Loss of information
If the gateway processes all received signals simultaneously without selection, then no signal processing is lost, but the gateway cannot handle more signals than its demodulator capacity allows
Solution Approach 1:
The gateway performs preliminary sorting of signals based on their communication end dates before processing. By organizing signals in temporal order and comparing against current capacity, the gateway preemptively selects which signals to process and which to reject, preventing information loss for prioritized signals while maintaining productivity within demodulator constraints.
Solution Approach 2:
The gateway dynamically adjusts its signal acceptance decisions based on real-time capacity conditions. Rather than using a static acceptance policy, the gateway continuously evaluates its demodulator availability and adapts its signal processing queue, allowing it to maximize throughput when capacity is available and gracefully degrade when overloaded, thus balancing information completeness with processing productivity.
3Adaptability or versatility
If the gateway accepts all data signals without load control, then the coverage and connectivity are maximized, but the gateway performance degrades under heavy load
Solution Approach 1:
The gateway employs feedback-based load control by continuously monitoring the number of simultaneous signal processing tasks against its demodulator capacity. When load exceeds capacity, the gateway provides feedback by rejecting additional signals and can implement dynamic threshold adjustments, maintaining reliable processing quality for accepted signals while preserving adaptability to connect with diverse communication modules within capacity limits.
