Network Slice Handover Control for 5G Throughput Bottlenecks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 5G network management systems fail to prevent throughput degradation due to the increasing number of user terminals in a coverage area, leading to suboptimal communication quality.
Innovation Solution
A network management apparatus and method that analyzes user data packets to identify network slices and determines whether to offload user terminals from a 5G base station to a 4G base station based on the number of connected terminals and the required network slice, using a slicing controller to manage network slicing and handover processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If UEs select base station based on received signal strength, then connection is established, but throughput is degraded when many UEs are in the coverage area
Solution Approach 1:
The network management apparatus continuously monitors the number of connected UEs and throughput metrics, then dynamically adjusts base station selection guidance to provide feedback to UEs. This feedback mechanism enables the system to respond to changing network conditions and prevent throughput degradation before it occurs.
Solution Approach 2:
The network management apparatus acts as an intermediary between UEs and base stations, controlling the base station selection process rather than allowing UEs to autonomously select based solely on signal strength. This intermediary control enables optimized load distribution across base stations while maintaining reliable connections.
2Productivity
If 5G base stations are expanded to provide high throughput, then communication capacity increases, but bottleneck occurs when many users gather in communication-concentrated areas
Solution Approach 1:
The system segments the user base by network slice type and distributes them across different base stations based on slice requirements and current load conditions. This segmentation prevents concentration bottlenecks by dividing the user population into manageable groups that can be independently managed.
Solution Approach 2:
The network management apparatus dynamically adjusts the base station selection strategy based on real-time network conditions, including the number of connected UEs, throughput metrics, and network slice requirements. This dynamic adaptation allows the system to maintain throughput guarantees even as user distribution changes.
3Ease of operation
If UEs autonomously select base station based on signal quality, then connection setup is simple, but throughput degradation cannot be avoided in high-density areas
Solution Approach 1:
The network management apparatus serves as an intermediary that receives base station selection requests from UEs, evaluates current network conditions, and provides optimized base station recommendations. This maintains operational simplicity for UEs while enabling intelligent load management to prevent throughput degradation.
Solution Approach 2:
The system provides feedback to UEs regarding optimal base station selection based on real-time network conditions. This feedback mechanism maintains ease of operation for UEs while ensuring that base station selections are optimized to prevent throughput degradation in high-density areas.
