Solution Overview
Problem
Existing communication systems lack the ability to analyze signaling traffic, making it difficult for operators to identify and address anomaly signaling traffic, which leads to signaling storms that consume radio resources and increase communication loads.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the number of services provided by the communications terminal increases, then the data transmission rate and service capability are improved, but the number of signaling messages transmitted increases dramatically, causing signaling storm
Solution Approach 1:
The patent extracts and analyzes only the essential characteristic information from the signaling messages (such as message type, source address, destination address) rather than processing all signaling traffic in detail. This selective extraction allows the system to identify anomaly patterns without being overwhelmed by the volume of signaling messages, thus resolving the contradiction between service capability and signaling message quantity.
Solution Approach 2:
The patent creates a simplified model or copy of the signaling traffic characteristics for analysis purposes. By working with extracted characteristic information rather than the full signaling messages, the system can perform anomaly detection and traffic analysis efficiently, reducing the impact of signaling storm while maintaining the ability to provide diverse services.
2Ease of manufacture
If conventional IP application and protocol design is used without considering future expansion, then the current protocol implementation is simple, but a large number of extra signaling messages are generated in the communications system
Solution Approach 1:
The patent performs preliminary analysis of signaling traffic characteristics and identifies anomaly patterns before they cause significant problems. By detecting and addressing signaling storm issues early through characteristic information analysis, the system can prevent the need for complex protocol changes later, maintaining implementation simplicity while reducing unnecessary signaling messages.
3Ease of operation
If existing server monitors signaling traffic without further analysis, then the monitoring function is simple, but the operator cannot identify or address anomaly signaling traffic
Solution Approach 1:
The patent introduces feedback by analyzing the extracted characteristic information from signaling messages and providing actionable insights back to the operator. The system monitors signaling traffic, identifies anomaly patterns through characteristic information analysis, and provides feedback about the sources and types of abnormal signaling, enabling the operator to take corrective actions while maintaining simple monitoring operations.
Solution Approach 2:
The patent changes the parameters of monitoring from simple traffic counting to analysis of characteristic information (message type, source/destination addresses, timing patterns). This parameter transformation enables anomaly detection while keeping the monitoring function relatively simple, as it still processes signaling traffic data but focuses on specific characteristics rather than all message content.
4Productivity
If signaling traffic is not analyzed, then the communication system operates with low processing load, but the operator cannot reduce the impact of signaling storm on the communications system
Solution Approach 1:
The patent extracts only the essential characteristic information from signaling messages for analysis, rather than processing the complete signaling traffic. This selective extraction approach enables the operator to analyze and address signaling storm issues while keeping the processing load manageable, as only key parameters (message type, addresses, timing) are processed rather than all signaling data.
