Dynamic Network Slice Allocation for Application-Specific QoS
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional telecommunication networks allocate default network slices to user equipment (UE) without considering application usage patterns, leading to suboptimal Quality of Service (QoS) and underutilization of network resources, which affects user experience.
Innovation Solution
A method for dynamic network slice allocation that monitors UE application usage patterns, classifies UEs into categories based on these patterns, and allocates network slices with predefined QoS, allowing redirection to optimal slices without changing the Single Network Slice Selection Assistance Information (S-NSSAI) value, and updates slices based on Mean Opinion Score (MOS) and movement patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If default network slice allocation is used without considering application usage patterns, then network configuration is simple and stable, but Quality of Service (QoS) is suboptimal and network resources are underutilized
Solution Approach 1:
The patent implements dynamic network slice allocation where the network slice assigned to UE changes based on real-time application usage patterns. The system continuously monitors application usage and dynamically reassigns network slices to match current service requirements, transforming the static default allocation into an adaptive dynamic system that optimizes QoS for different applications.
Solution Approach 2:
The system changes the network slice parameter assignment based on application usage patterns. By monitoring which applications the UE is using and adjusting the network slice parameter accordingly, the system adapts the network configuration to match the specific QoS requirements of different applications, thereby improving overall service quality.
2Adaptability or versatility
If dynamic slice allocation based on usage pattern is implemented, then QoS is optimized for each application, but system complexity increases
Solution Approach 1:
The patent segments UEs into different categories based on their application usage patterns. By classifying UEs into distinct groups (such as gaming users, video streaming users, browsing users), the system can apply different network slice allocation strategies to each segment, making the complex adaptation task more manageable through categorical division.
Solution Approach 2:
The system implements a feedback mechanism where application usage patterns are continuously monitored and fed back to the network slice allocation decision. This closed-loop feedback allows the system to adaptively adjust network slice assignments based on actual usage behavior, ensuring that the network configuration remains optimized for current application requirements.
3Reliability
If network slice is changed to optimize QoS, then service quality improves, but network connectivity stability may be affected
Solution Approach 1:
The patent performs preliminary classification of UEs into categories based on application usage patterns before executing network slice changes. By pre-categorizing UEs and preparing appropriate network slice assignments in advance, the system can smoothly transition between slices without causing connection disruptions or instability during the switching process.
