5G QoS Configuration via Application Server Profiles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing network technologies face challenges in efficiently associating data with appropriate levels of quality of service (QoS) due to insufficient information about the data types and their network sensitivity and tolerance levels.
Innovation Solution
A method where a computing device receives QoS information from an application or service server and generates a QoS profile indicating the associated QoS flow identifiers (QFIs). This profile is sent to a user device, which selects a QFI and requests a PDU session modification to implement the chosen QoS level.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the network transports data without detailed QoS information about data sensitivity, then the network operation is simple, but the QoS association accuracy deteriorates
Solution Approach 1:
The QoS information is collected and the QoS profile is generated in advance by the QMF before data transmission begins. This preliminary action includes receiving QoS information from the application server, generating the QoS profile with appropriate QFIs, and preparing the configuration data so that when data needs to be transmitted, the correct QoS association is already established, improving accuracy without adding operational complexity during actual data transfer
Solution Approach 2:
The QoS Management Function (QMF) acts as an intermediary between the application server and the network elements. It receives QoS information from the application server, processes this information to generate appropriate QoS profiles, and then communicates with the network elements to establish proper QoS associations. This intermediary role centralizes the complexity management while improving QoS association accuracy
2Reliability
If the network provides multiple QoS levels with different guarantees, then the QoS service quality improves, but the device complexity increases
Solution Approach 1:
The system changes parameters by defining specific QoS parameters (latency guarantees, throughput guarantees, etc.) and associating them with different QoS levels. The QMF receives QoS information containing these parameters and generates QoS profiles that map appropriate QFIs to data flows based on these parameter requirements, enabling differentiated QoS service quality while managing complexity through parameter-based configuration
Solution Approach 2:
The QoS information is segmented into distinct QoS levels, each with specific guarantees for latency, throughput, and other parameters. The QoS profile segments the configuration by associating different QFIs with different QoS levels, allowing the network to handle different types of data with appropriate QoS treatments without requiring complex monolithic configuration

AI summary
Systems, apparatuses, and methods are described for configuring quality of service (QoS). For example, a computing device, which may be configured to operate as one or more network functions of a fifth generation wireless system (5G), may be associated with a first network. The computing device may receive, from an application or service server, and via a second network, QoS information. The QoS information may associate an application or service with one or more QoS flow identifiers (QFIs) or other indicator of a level of QoS. A PDU session may be established for a user device and the application or service. Based on the QoS information, the computing device may send a request that causes the PDU session to be modified. Upon modification, the PDU session may transport, based on data including the QFI or other indicator of a level of QoS, the data via the first network.
