Dynamic QoS Profile Adaptation for 5G Network Resource Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
5G networks face inefficiencies due to static QoS profiles that lead to overutilization of network resources and inability to adapt quickly to dynamic application behavior, particularly in scenarios where applications change states frequently, leading to potential network overload and service quality deterioration.
Innovation Solution
A method and network function, implemented via a broker, dynamically adjusts the access network's service profile based on current application mode and network status using exposure interfaces, enabling near-real-time adaptation and resource optimization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single static QoS profile is assigned to applications and user equipment, then service continuity is maintained, but network resources are overutilized and cannot adapt to dynamic application behavior
Solution Approach 1:
The patent implements dynamic QoS profile adaptation by introducing a network function that monitors application behavior and automatically switches between multiple QoS profiles based on current application state and network conditions, transforming the static single-profile system into a dynamic multi-profile system that adapts to changing requirements
Solution Approach 2:
The patent changes QoS parameters by maintaining multiple QoS profiles with different parameter sets and selecting the appropriate profile based on application state, thereby adjusting parameters such as bandwidth allocation, priority, and latency requirements dynamically without requiring full QoS flow modification
2Reliability
If the QoS profile is modified to meet the highest requirements, then application performance is ensured, but significant signaling effort is required and network resources are overutilized
Solution Approach 1:
The patent applies partial action by modifying only the necessary QoS parameters through selective profile switching rather than completely reconfiguring the entire QoS flow, thereby achieving the required performance adjustment with reduced signaling overhead and network impact
3Adaptability or versatility
If existing QoS adaptation functions are used, then network condition-based QoS changes are supported, but application state changes are not considered and adaptation cannot occur in near real-time
Solution Approach 1:
The patent implements feedback mechanisms by introducing a network function that continuously monitors both application state and network conditions, using this feedback information to dynamically select appropriate QoS profiles and trigger adaptations in near real-time based on actual system state rather than predefined conditions

AI summary
A method for initiating an adaptation of an access network. The method includes: determining an assignment between an application mode of an application and a service profile of an access network of a communications network based on received information relating to the access network and/or the application; retrieving a current network status of the access network and/or a current application mode; checking the current network status based on an assessment of whether the service profile of the access network satisfies a requirement for a current quality of service for the associated particular application mode and, based on the result of the check being positive, verifying the current application mode on the basis of an assessment of whether the application mode of the application has changed and, based on the result being positive, initiating an adaptation of the access network based on the current application mode and the determined assignment.
