SMS Message Center Dynamic Flow Control Threshold
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current short message service (SMS) flow control methods are inadequate, as they rely on fixed thresholds that fail to accurately reflect the operational status of Mobile Switching Centers (MSC), leading to inefficient resource allocation and user experience issues during peak periods.
Innovation Solution
A method where the SMS message center dynamically sets the terminated flow control threshold based on the operation blocking level of the MSC, using failure reason codes to adjust the threshold in real-time, ensuring effective flow control by configuring and calculating control attributes and adjustment values to reflect current network conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fixed flow threshold is preset for MSC, then the flow control is simple to implement, but the threshold cannot accurately reflect the actual operational status of MSC, leading to either excessive resource occupation or unnecessary message suspension
Solution Approach 1:
The patent transforms the fixed threshold into a dynamic threshold that automatically adjusts based on real-time MSC operational status. The system continuously monitors MSC blocking status and modifies the flow threshold accordingly, enabling the threshold to adapt to changing network conditions rather than remaining static. This resolves the contradiction by making the threshold both implementable (through automated adjustment) and accurate (by reflecting actual MSC status).
Solution Approach 2:
The patent implements a feedback mechanism where the SMS message center monitors the operational status of MSC and uses this information to adjust the flow threshold. The system receives feedback about MSC blocking conditions and automatically modifies the threshold to match actual network capacity. This feedback loop ensures the threshold remains accurate while maintaining simple implementation through automated control.
2Productivity
If the flow threshold is set high to avoid suspending messages, then more messages can be delivered, but the MSC occupies excessive system and wireless resources during peak periods
Solution Approach 1:
The system dynamically adjusts the flow threshold based on real-time MSC operational status and network conditions. During peak periods when MSC is busy, the threshold automatically decreases to reduce resource occupation, while during off-peak periods when MSC is idle, the threshold increases to maximize message delivery. This dynamic adjustment resolves the contradiction by optimizing both message delivery volume and resource utilization at different times.
Solution Approach 2:
The patent changes the parameter of flow threshold based on varying network conditions and MSC operational status. The system monitors parameters such as MSC blocking status and adjusts the threshold parameter accordingly. This parameter change enables the system to adaptively balance between message delivery volume and resource consumption, resolving the contradiction between productivity and energy loss.
3Reliability
If the flow threshold is set low to prevent MSC overload, then system resources are protected, but many valid messages are unnecessarily suspended and user experience is affected
Solution Approach 1:
The system dynamically adjusts the flow threshold to match actual MSC capacity, preventing both overload and unnecessary suspension. When MSC is truly overloaded, the threshold decreases to protect resources, but when MSC recovers, the threshold automatically increases to resume message delivery. This dynamic behavior ensures reliability through resource protection while maintaining productivity by avoiding unnecessary message suspension.
Solution Approach 2:
The system uses feedback about MSC operational status to automatically adjust the flow threshold. When MSC indicates it can handle more messages, the threshold increases to improve message delivery availability. When MSC shows signs of overload, the threshold decreases to protect resources. This feedback mechanism resolves the contradiction by ensuring both reliability and productivity through adaptive control.
4Device complexity
If the flow control uses fixed threshold, then the control logic is simple, but it cannot adapt to holiday peaks or network condition changes
Solution Approach 1:
The patent implements dynamic threshold adjustment that automatically adapts to network condition changes without requiring complex manual intervention. The system monitors MSC operational status and automatically modifies the flow threshold in response to holiday peaks, network maintenance, or other conditions. This dynamic approach maintains relatively simple control logic while achieving high adaptability to varying network environments.
Solution Approach 2:
The system performs self-adjustment of the flow threshold based on real-time monitoring of MSC status. Rather than requiring external manual configuration for different network conditions, the system automatically detects and responds to changes in network capacity and messaging patterns. This self-service capability maintains simple control logic while providing versatile adaptation to different operational scenarios.
