Slice AMBR Segmentation for Precise 5G Traffic Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication systems lack a method to effectively control traffic of a single terminal device in a slice, particularly in 5G networks, which affects bandwidth utilization.
Innovation Solution
Implementing a communication method that utilizes an Aggregated Maximum Bit Rate (AMBR) parameter to manage the quantity of Guaranteed Bit Rate (GBR) and Non-GBR resources within a slice, determining a second AMBR based on the first AMBR, session-AMBR, and flow control bit rate of a QoS flow to perform accurate traffic control.

Engineering Contradiction Analysis
1Productivity
If AMBR parameter is used to limit total rate of subscriber, then bandwidth utilization is maximized, but traffic control accuracy for single terminal device in slice is insufficient
Solution Approach 1:
The patent segments the aggregate AMBR parameter into separate GBR (Guaranteed Bit Rate) and non-GBR (non-Guaranteed Bit Rate) resource components. By dividing the total rate limitation into distinct resource types with different control mechanisms, the system achieves both high bandwidth utilization through aggregate management and precise traffic control for individual terminal devices within slices through dedicated GBR/non-GBR allocation.
2Productivity
If aggregate AMBR is used for slice resource management, then overall resource allocation is efficient, but precise control of GBR and non-GBR resources for individual terminals is lacking
Solution Approach 1:
The patent segments the aggregate AMBR parameter into separate GBR and non-GBR resource components. By dividing the total rate limitation into distinct resource types with different control mechanisms, the system achieves both high bandwidth utilization through aggregate management and precise traffic control for individual terminal devices within slices through dedicated GBR/non-GBR allocation.
Solution Approach 2:
The patent implements dynamic adjustment of GBR and non-GBR resource allocations based on real-time network conditions and service requirements. The system can dynamically modify the split between guaranteed and non-guaranteed resources while maintaining the overall AMBR constraint, enabling flexible resource management that adapts to changing traffic patterns and service quality requirements.

AI summary
In a communication method, the method includes: receiving a first AMBR of a slice, where the first AMBR indicates a quantity of GBR resources and a quantity of non-GBR resources in the slice, and the first AMBR is a subscribed slice AMBR or an authorized slice AMBR; determining a second AMBR of the slice based on the first AMBR, a session-AMBR of an activated PDU session of the slice, and a flow control bit rate of a QoS flow of the activated PDU session of the slice, where the flow control bit rate is a GFBR or an MFBR; and performing traffic control on the slice based on the second AMBR. The AMBR of the slice may indicate a quantity of GBR resources and a quantity of non-GBR resources in the slice.
