Policy Control Function QoS Monitoring with Batch Reports
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing wireless communication networks face challenges in managing a large number of communication sessions efficiently due to the significant number of signaling messages generated by real-time Quality of Service (QoS) monitoring, which can hinder network efficiency and the need for immediate actions based on QoS monitoring reports.
Innovation Solution
Implementing a Policy Control Function (PCF) in the 5G core network to initiate QoS monitoring independently of requests from Application Function (AF) or Network Exposure Function (NEF), with the capability to generate QoS monitoring policies, collect reports, and perform actions based on these reports, and send batch reports to AF or NEF when specific trigger conditions are met.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If real-time QoS monitoring is implemented for each communication session, then QoS management capability is improved, but the number of signaling messages increases significantly
Solution Approach 1:
The patent combines multiple QoS monitoring reports into a single batch report that is sent from the SMF to the PCF. Instead of sending individual reports for each communication session separately, the system aggregates reports from multiple sessions into one consolidated message, thereby reducing the total number of signaling messages while maintaining comprehensive QoS monitoring capability across all sessions.
2Measurement precision
If individual QoS monitoring reports are sent for each communication session, then monitoring precision is improved, but network efficiency deteriorates
Solution Approach 1:
The system implements periodic batch reporting where the SMF collects QoS monitoring reports from multiple communication sessions over a defined time period or based on trigger conditions, then sends them together in a single batch report to the PCF. This periodic aggregation maintains precise monitoring of individual sessions while improving network efficiency by reducing the frequency of signaling transmissions.
3Adaptability or versatility
If QoS monitoring is activated by AF or NEF requests, then service customization is improved, but system complexity increases
Solution Approach 1:
The patent enables the PCF to proactively activate QoS monitoring for communication sessions based on pre-configured policies and trigger conditions, without waiting for requests from AF or NEF. The PCF can determine in advance which sessions require monitoring based on subscription information, service type, or other criteria, thereby simplifying the system by reducing the number of external request-handling interfaces while maintaining service customization capabilities.
Data Source
AI summary
A device may include a processor configured to determine that Quality of Service (QoS) monitoring is to be performed for a communication session; generate a QoS monitoring policy for the communication session; and provide the QoS monitoring policy to a Session Management Function (SMF) associated with the communication session. The processor may be further configured to receive a QoS monitoring report for the communication session from the SMF and perform an action based on the received QoS monitoring report.
