VAS-SMS Processing Center Intermediary Control Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Short Message Service Centers (SMSCs) face increased burden and inconvenience when adapting to new value-added services, as existing solutions lack a comprehensive mechanism for controlling the processing flow of value-added services, leading to inefficiencies in managing SMS processing.
Innovation Solution
A VAS-SMS processing center is introduced to receive original short messages, generate value-added service messages based on subscriber data, submit these messages to the SMSC, and manage delivery status reports, ensuring seamless transition between original and value-added service message flows, thereby enhancing control and flexibility in SMS processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a VAS-SMS processing center is introduced to process value-added services centrally, then the flexibility of developing new value-added services is improved and the burden on the short message service center is reduced, but the control mechanism between the processing center and the short message service center becomes more complex
Solution Approach 1:
The patent introduces a VAS-SMS processing center as an intermediary component between the short message service center and value-added service processing. This mediator handles value-added service processing centrally, allowing new services to be developed without modifying the core SMSC, while maintaining a defined control mechanism through standardized interfaces and message forwarding protocols.
Solution Approach 2:
The patent segments the SMS processing system into distinct functional components: the short message service center for core messaging functions, and the VAS-SMS processing center for value-added service processing. This segmentation allows independent development and maintenance of each component, improving flexibility while managing complexity through clear functional boundaries.
2Adaptability or versatility
If the additional network entity executes partial processing of value-added services, then the flexibility of developing new value-added services is improved, but the control of the short message processing flow is weakened
Solution Approach 1:
The patent implements a feedback mechanism where the VAS-SMS processing center receives delivery status reports from the short message service center and uses this information to control the processing flow. The delivery result of the value-added service short message is taken as that of the associated original short message, ensuring proper flow control while maintaining processing flexibility.
Solution Approach 2:
The patent employs preliminary action by having the VAS-SMS processing center generate value-added service short messages based on directives stored in advance. The processing center receives the original short message, generates the value-added message according to pre-defined rules and subscriptions, and then submits it to the SMSC, ensuring controlled processing flow while maintaining flexibility.

AI summary
A processing method and processing center of a short message value added service are provided, so as to consummate a control mechanism between the short message value added service processing center and a short message center. Wherein, the processing center of the short message value added service (4) receives an original short message transmitted by the short message center (3), and generates the short message of the value added service associated with the original short message according to the data of the short message value added service, which is signed by both the calling and called parties of the original short message, then the short message of the value added service is provided to the short message center (3). The processing center of the short message value added service (4) receives a status report adown sent from the short message center (3). The processing center of the short message value added service (4) makes the adown sent result of the short message of the value added service as the result adown sent associated with the original short message, and notifies the short message center (3) of the result message adown sent of the original short message.
