SSP Intelligent Trigger Management for Call Continuity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Abnormal situations such as disconnection or congestion between a Service Switching Point (SSP) and a Service Control Point (SCP) in mobile communication technologies hinder normal call processing for intelligent users, as the SSP relies on the SCP for instructions and cannot independently manage intelligent calls.
Innovation Solution
The SSP detects abnormal traffic conditions and turns off intelligent triggers, treating the call as an ordinary call, allowing it to continue processing without SCP instructions, and notifies subsequent SSPs to handle the call accordingly, ensuring communication continuity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the SSP relies on the SCP for intelligent call instructions, then call processing accuracy is improved, but system reliability deteriorates when traffic between SSP and SCP is abnormal
Solution Approach 1:
The SSP is equipped with the capability to independently judge whether traffic with the SCP is abnormal and to autonomously switch between intelligent and ordinary call processing modes. This self-service mechanism allows the SSP to make decisions without continuous SCP intervention, ensuring call processing continues even when SCP communication is disrupted.
Solution Approach 2:
The system performs preliminary detection of traffic abnormality between SSP and SCP before intelligent call processing begins. By detecting traffic status in advance and preparing alternative processing paths, the system can seamlessly switch to ordinary call processing if abnormalities are detected, preventing call failures.
2Ease of operation
If the SSP continuously communicates with the SCP for intelligent call instructions, then service quality is improved, but system complexity increases
Solution Approach 1:
The system dynamically adjusts the call processing mode based on real-time traffic conditions between SSP and SCP. When traffic is normal, intelligent call processing with SCP interaction is used; when traffic is abnormal, the system automatically switches to ordinary call processing. This dynamic adaptation simplifies the system by reducing unnecessary communication overhead while maintaining service quality.
3Duration of action of stationary object
If the SSP detects and responds to traffic abnormalities by switching to ordinary call processing, then call continuity is improved, but processing efficiency decreases
Solution Approach 1:
The system applies preliminary anti-action by detecting traffic abnormalities before they cause call failures. By identifying problematic traffic conditions in advance and proactively switching to ordinary call processing, the system prevents call interruptions while avoiding the need for complex recovery procedures, thus maintaining both call continuity and reasonable processing efficiency.

AI summary
A method of ensuring call processing for an intelligent user, including: upon receiving a call, judging, by a first Service Switching Point (SSP), whether traffic between the first SSP and a Service Control Point (SCP) is abnormal; if the traffic is abnormal, turning off, by the first SSP, intelligent triggers located in itself and related to the call, and performing an ordinary call connection; otherwise, performing an intelligent call connection, and terminating the process. In the embodiments of the present invention, normal communications can be ensured between intelligent users, even if the traffic between the SSP and the SCP is abnormal. In addition, when the SSP detects that the traffic between the SSP and the SCP is abnormal, the SSP may firstly judge whether to continue the call connection, according to relations among intelligent user identities, reasons for abnormality and whether to perform call connection set in advance, instead of blindly performing call connections for all the intelligent users, thereby preventing excessive service load on the SSP.
