Advice of Charge Information Transmission via Charging Session Channel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Advice of Charging (AoC) supplementary services in communication systems are not well-supported for data services, lacking flexibility in information customization and transmission, and rely on third-party interfaces, which complicates the process and limits user control and transparency.
Innovation Solution
A method and system that allows for dynamic AoC information transmission using established charging session channels, enabling user customization of content and trigger conditions, and direct communication between the charging system and application server, simplifying the process and enhancing information richness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the AoC supplementary service uses third-party interfaces for information transmission, then the service can be implemented in voice calls, but the process becomes complicated and flexibility is reduced
Solution Approach 1:
The patent merges the AoC information transmission function with the existing charging session channel. The charging system directly sends AoC information to the application server through the established charging interface, eliminating the need for separate third-party transmission interfaces. This integration simplifies the overall process while maintaining reliable service implementation.
2Ease of manufacture
If the charging system uses fixed format AoC information, then the implementation is simple, but the user cannot customize the information to fit their requirements
Solution Approach 1:
The patent introduces dynamic customization capabilities where users can define their own AoC information formats and trigger conditions. The system allows users to specify what information they want to receive (such as balance thresholds, service types) and when they want to receive it, transforming the fixed-format system into a flexible, user-adaptable one while maintaining implementation feasibility through standardized interfaces.
3Ease of operation
If the user cannot choose whether to accept AoC information, then the system is simple to operate, but the user lacks control and flexibility
Solution Approach 1:
The patent enables users to self-configure their AoC preferences by allowing them to customize information formats, set trigger conditions (such as balance thresholds), and choose which services they want monitoring. This self-service approach gives users full control over their AoC experience while keeping the system operationally simple through standardized configuration mechanisms.
4Stability of the object's composition
If the AoC information is transmitted through separate interfaces, then the charging system can maintain independence, but the transmission process becomes more complex
Solution Approach 1:
The patent makes the charging session channel multi-functional by using it for both its original charging purposes and for AoC information transmission. The existing charging interface between the charging system and application server is leveraged to carry AoC information alongside charging data, eliminating the need for separate dedicated transmission interfaces while maintaining system independence and architectural stability.

AI summary
The present invention provides a method and system for implementing an AoC supplementary service so as to conveniently provide the user with more enriched AoC information. The method comprises: an application server receiving a service request initiated by a user terminal; the AS establishing a charging session with a charging system after receiving the request; the charging system transmitting the AoC information to the application server through a channel for the charging session and the application server transmitting the AoC information to the user terminal. The system of the present invention comprises: a user terminal, an application server, and a charging system; the user terminal is adapted to transmit a service request to the application server; the application server is adapted to establish a charging session with the charging system after receiving the request; the charging system transmits the AoC information to the application server through a channel for the charging session. The present invention can simplify the transmission of the AoC information and enrich the content contained in the AoC information.
