PCRF Selective Event Report Forwarding for Telecom Resource Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing Policy and Charging Control (PCC) mechanism in telecom networks wastes network resources by forwarding all event reports from BBERF to PCEF and vice versa, leading to redundant information and excessive resource consumption, as it does not allow for selective reporting based on actual requirements.
Innovation Solution
A method where BBERF and PCEF register their required event report types with the Policy and Charging Rules Function (PCRF), enabling the PCRF to forward only necessary event reports, thereby reducing redundant information exchange and conserving resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the PCRF forwards all event reports from BBERF to PCEF and vice versa, then complete information transfer is achieved, but network resources are wasted due to redundant information
Solution Approach 1:
The patent extracts and identifies the specific event report types that are actually needed by each entity (BBERF and PCEF). Through subscription mechanisms, each entity declares which event types it requires, and the PCRF selectively forwards only those matching event reports, extracting the necessary information while discarding redundant data.
Solution Approach 2:
Instead of forwarding all event reports (excessive action), the system implements partial forwarding based on subscription requirements. The PCRF forwards only the subset of event reports that match the subscribed types, avoiding the waste of resources on unnecessary information while ensuring all required information is transmitted.
2Loss of information
If the PCRF forwards all event reports between BBERF and PCEF, then no information is lost, but the load on PCRF nodes increases excessively
Solution Approach 1:
The system extracts the essential filtering function by implementing subscription-based event type declarations. The PCRF extracts only the necessary event reports based on matched subscription criteria, reducing the processing burden while maintaining information completeness for required events.
Solution Approach 2:
The patent applies partial action by forwarding only the necessary subset of event reports rather than all reports. This selective forwarding based on subscription matching reduces the processing load on PCRF nodes while ensuring all required event information is delivered.
3Reliability
If the PCRF forwards all event reports, then comprehensive monitoring is achieved, but redundant information exchange occurs
Solution Approach 1:
The system extracts the specific event types needed through subscription mechanisms. Each entity declares which event types it needs to monitor, and the PCRF extracts and forwards only those matching event reports, ensuring comprehensive monitoring of required events while eliminating redundant information exchange.
Solution Approach 2:
The patent implements partial forwarding by sending only the necessary event reports based on subscription matching. This ensures that all required event types are monitored and transmitted while avoiding the waste of network signaling resources on redundant information.

AI summary
A method of information transfer, comprising receiving an event report and sending the event report if the report matches event report subscription information. A policy and charging rule function (PCRF) and mobile communication system are also disclosed in the present invention, thereby enabling the system to save network resources and increase the utilization of network resources.
