CTF Module Aggregating Network Service Requests for Bandwidth Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current telecommunication networks face high bandwidth requirements due to the large number of message exchanges between the Charging Trigger Function (CTF) and the Online Charging System (OCS) for real-time online charging, which is inefficient and limits bandwidth optimization.
Innovation Solution
Implementing a method that aggregates network service requests with common attribute-value pairs (AVPs) to generate master service request messages, reducing redundant data exchange by using a Traffic Flow Filter and Traffic Flow Aggregator to identify and combine similar requests, thereby reducing bandwidth requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If individual service requests are transmitted separately for each user, then real-time charging authorization is achieved, but bandwidth consumption and message exchange volume increase significantly
Solution Approach 1:
The patent combines multiple individual service requests from different users into a single aggregated master service request message. The CTF module identifies common AVPs across multiple requests and merges them, transmitting only one aggregated message to the OCS module while maintaining the ability to provide real-time charging authorization for each individual user through the aggregated response.
2Loss of energy
If message aggregation is implemented to reduce bandwidth, then bandwidth efficiency improves, but message processing complexity increases
Solution Approach 1:
The patent segments the message aggregation process into distinct functional components: the CTF module handles message collection and aggregation, identifying common AVPs and creating master service request messages, while the OCS module handles processing and response generation. This segmentation distributes processing complexity across different modules rather than concentrating it in one component.
Solution Approach 2:
The CTF module acts as an intermediary between individual user service requests and the OCS module. It receives multiple individual requests, aggregates them into a master service request message, and forwards this aggregated message to the OCS module, thereby simplifying the overall processing architecture.
3Loss of information
If all service request details are transmitted for each user, then complete charging information is available, but data volume and processing overhead increase
Solution Approach 1:
The patent extracts and identifies common AVPs from multiple individual service requests and removes redundant duplicates. Only the unique and user-specific AVPs are retained in the aggregated master service request message, thereby reducing data volume while preserving all necessary charging information through the combination of common and user-specific elements.

AI summary
A method, in a wireless telecommunication network, for aggregating network service requests between a charging trigger function, CTF, module and an Online Charging System, OCS, module of the network within a given time window, the method comprising determining, at the CTF or OCS module, a subset of service request messages from the multiple received service request messages with multiple common attribute-value pairs, AVPs, and generating a master service request message using the subset of service request messages by aggregating the subset of service request messages, the master service request message including user specific AVPs.
