Slice AMBR Policy Control for Single-Terminal Traffic Management
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 terms of uplink and downlink traffic, which affects bandwidth utilization.
Innovation Solution
Implement a communication method that utilizes an AMBR parameter to manage the quantity of GBR and non-GBR resources within a slice, determining a second AMBR based on a first AMBR, session-AMBR, and flow control bit rate to perform accurate traffic control, including methods to allocate or discard resources as needed.

Engineering Contradiction Analysis
1Productivity
If an AMBR parameter is used to limit the total rate of a subscriber, then bandwidth utilization is maximized, but there is no corresponding method to control traffic of a single terminal device in a slice
Solution Approach 1:
The patent segments the AMBR parameter into two distinct components: a first AMBR parameter for GBR (Guaranteed Bit Rate) resources and a second AMBR parameter for non-GBR (Non-Guaranteed Bit Rate) resources. This segmentation allows independent control and management of different resource types within a slice, enabling precise traffic control for single terminal devices while maintaining overall bandwidth utilization efficiency.
2Ease of operation
If traffic control is performed without separating GBR and non-GBR resources, then the control method is simple, but the accuracy of traffic control is insufficient
Solution Approach 1:
The patent divides the traffic control mechanism into two separate AMBR parameters: one for GBR resources and another for non-GBR resources. This segmentation enables accurate tracking and control of each resource type independently, significantly improving traffic control accuracy while maintaining manageable complexity through standardized procedures for each parameter type.
Solution Approach 2:
The patent applies different control strategies and parameters locally to different resource types. GBR resources receive guaranteed bit rate control through the first AMBR parameter, while non-GBR resources receive best-effort control through the second AMBR parameter. This localized quality approach ensures each resource type is controlled with appropriate precision and methodology.

AI summary
In a communication method, the method includes: obtaining a subscribed aggregated maximum bit rate (AMBR) of a slice, wherein the subscribed AMBR indicates a quantity of guaranteed bit rate (GBR) resources and a quantity of non-GBR resources in the slice; determining policy information based on the subscribed AMBR, wherein the policy information comprises at least one of a session-AMBR of a session or a flow control bit rate of a QoS flow of the session; and sending the policy information to a session management network element
