Real-time Charging System QoS Rule Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional real-time charging systems in communication systems lack efficient mechanisms to update Quality of Service (QoS) and charging rules in real-time, leading to traffic overload and delayed quota re-allocation when QoS and charging rules change during service.
Innovation Solution
Implementing a communication interface between the real-time charging function server and the QoS and charging rule management server using the Diameter protocol to enable direct notification and updating of QoS and charging rules, allowing for real-time quota allocation and re-allocation based on changing service conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the conventional method is used where the real-time charging function server informs the packet processing node of QoS and charging rule changes, then the packet processing node can be notified of changes, but this increases traffic overload in the network
Solution Approach 1:
The invention introduces a new communication interface between the real-time charging function server and the QoS and charging rule management server as an intermediary mechanism. This allows direct notification of QoS and charging rule changes without routing messages through the packet processing node, thereby reducing network traffic overload while ensuring reliable delivery of change notifications.
2Adaptability or versatility
If the packet processing node re-requests quota allocation from the real-time charging function server, then updated quotas can be obtained, but QoS and charging rules cannot be changed before this re-request occurs
Solution Approach 1:
The invention enables the QoS and charging rule management server to receive and process QoS and charging rule change requests in advance, before the packet processing node re-requests quota allocation. The server prepares the updated rules and proactively notifies the real-time charging function server, ensuring that quota changes can be applied immediately when the node requests new quotas, eliminating the delay where changes could not take effect.
3Productivity
If a direct communication interface is implemented between the real-time charging function server and the QoS and charging rule management server, then real-time quota allocation can be achieved, but system complexity increases
Solution Approach 1:
The invention implements a standardized communication interface using the Diameter protocol that serves multiple functions: notifying QoS and charging rule changes, transmitting quota allocation requests, and enabling real-time updates. This multi-functional interface achieves real-time quota allocation capability while avoiding the complexity of multiple separate communication mechanisms, as the same interface handles various messaging needs between the servers.

AI summary
Provided is a method and apparatus for controlling a charging condition and policy by a first entity, in which information for policy decision information is received from a second entity and an acknowledgement message is transmitted to the second entity. A policy based on the information for policy decision information is determined, the policy is transmitted to a third entity, and an acknowledgement message for the policy is received from the third entity.
