Application Program Control via QNC Notifications for Non-GBR Flows
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 5G mobile communication technologies struggle to optimize Quality of Service (QoS) control for non-guaranteed bit rate (non-GBR) QoS flows, leading to lagging issues in audio and video communication due to changes in wireless network states.
Innovation Solution
A QoS notification control (QNC) mechanism is implemented for non-GBR QoS flows, where application entities and core entities exchange notification messages to adapt application programs to changes in network parameters, adjusting computing and traffic policies to optimize network transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If QoS control is performed in units of QoS flow for non-GBR flows, then network resource allocation is achieved, but the system cannot actively adapt to wireless network state changes causing lag in audio and video communication
Solution Approach 1:
The patent implements a feedback mechanism where the access network device monitors QoS parameter changes and sends notification messages to the application entity. When parameters such as packet delay budget or packet error rate change and satisfy a reporting condition, the access network device actively notifies the application entity, enabling the application to adjust its behavior in response to network conditions.
Solution Approach 2:
The patent enables preliminary action by allowing the application entity to receive advance notification of QoS parameter changes before they significantly impact service quality. The access network device detects changes and sends notifications proactively, giving the application entity time to adjust computing or traffic policies before lag occurs in audio or video communication.
2Speed
If notification messages are transmitted for every QoS parameter change, then the application entity can respond quickly to network changes, but signaling overhead and system complexity increase
Solution Approach 1:
The patent applies partial action by implementing selective notification rather than notifying for every QoS parameter change. The access network device evaluates whether a change satisfies a reporting condition before sending a notification message. This selective approach transmits only necessary notifications, reducing signaling overhead while maintaining adequate response capability for significant network changes.

AI summary
This discloses relates to an application program control method and apparatus. The method includes that: an application entity receives a notification message transmitted by a core entity (320), the notification message indicating that a change in a parameter value of a quality of service notification control (QNC) of a non-guaranteed bit rate (GBR) bearer flow satisfies a reporting condition; and the application entity controls an application program according to the notification message (340). According to this application, the application entity may perceive a change in a wireless network state of the non-GBR bearer flow, and further actively control running of the application program according to the change.
