5G Network Exposure Function Performance Measurement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The 5G system faces challenges in monitoring the performance of network exposure function (NEF) services, particularly in data management, quality of service (QoS) for application functions (AF), and UE radio capability management, due to missing measurements for background data transfer policy application and UCMF provisioning, leading to potential service failures and performance degradation.
Innovation Solution
A performance measurements system is implemented to generate metrics for AF sessions with QoS, policy applications, and UCMF provisioning, including cumulative counters for various events like session creations, notifications, and policy applications, providing insights into the success and failure rates of these processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If performance measurements are implemented for NEF services, then monitoring capability and reliability are improved, but system complexity increases
Solution Approach 1:
The NEF performs self-measurement of its own performance metrics (session creation success rates, notification delivery, policy application) without requiring external monitoring systems. The measurement function is integrated within the NEF itself, allowing it to autonomously track and report on its operational status.
Solution Approach 2:
The measurement framework is designed to be universal and can monitor multiple types of NEF services (data management, QoS for AF, UE radio capability management) through a single integrated mechanism. The same measurement principles apply across different service types, eliminating the need for separate monitoring systems for each function.
2Measurement precision
If comprehensive measurements for all NEF services are collected, then measurement precision improves, but information processing complexity increases
Solution Approach 1:
The measurement framework divides NEF performance monitoring into distinct segments: data management service measurements, QoS for AF measurements, and UE radio capability management measurements. Each segment has its own specific metrics and collection methods, making the overall complex monitoring task manageable through modular organization.
Solution Approach 2:
The system collects performance measurement data and provides feedback reports to network operators and AFs. This feedback mechanism enables continuous improvement of service quality while keeping the data processing manageable through targeted collection and analysis of only the most relevant metrics.

AI summary
This disclosure describes systems, methods, and devices related to performance measurements. A device may decode a service request received from a management service consumer for the 5G system (5GS), wherein the service request may be associated with a performance measurement collection service to be delivered by the service producer to the service consumer related to a network exposure function (NEF). The device may detect performance measurements data received from the NEF. The device may decode from the performance measurements data a measurement label associated with the performance measurements data based on the service request. The device may encode a service response based on the performance measurements data received from the NEF.
