5G Session Bit Rate Control for Accurate AUN3 Establishment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, the session aggregate maximum bit rate (AMBR) of authenticable non-3rd generation partnership project (AUN3) devices can exceed the session establishment capability of a 5G-RG, leading to data transmission failures after session establishment.
Innovation Solution
Determine a target maximum bit rate for AUN3 devices based on the subscription data of a first device, ensuring it does not exceed the first device's maximum bit rate, thereby standardizing session establishment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the session AMBR of AUN3 is allowed to exceed the session establishment capability of 5G-RG, then the AUN3 subscription flexibility is improved, but the session establishment reliability deteriorates
Solution Approach 1:
The patent applies preliminary action by determining the target maximum bit rate before session establishment occurs. The SMF obtains subscription data of the first device, determines the target maximum bit rate for the second device based on this data, and ensures it does not exceed the first device's maximum bit rate before the session is actually established. This prevents the reliability issue from occurring in the first place rather than correcting it after session establishment.
Solution Approach 2:
The patent introduces an intermediary mechanism through the SMF's bit rate determination function. The SMF acts as an intermediary between the AUN3 device's subscription requirements and the 5G-RG's session establishment capability. It mediates by calculating and enforcing a target maximum bit rate that satisfies both the AUN3 subscription data and the 5G-RG capability constraints, preventing direct conflict between the two.
2Adaptability or versatility
If multiple AUN3 devices are connected to a single 5G-RG without binding relationships, then the system adaptability is improved, but the session establishment accuracy deteriorates
Solution Approach 1:
The patent applies local quality by implementing device-specific bit rate control. Each AUN3 device (second device) connected to the 5G-RG has its target maximum bit rate independently determined based on its own subscription data and the corresponding first device's subscription data. This localized control ensures accurate session establishment for each device while maintaining the overall flexibility of multiple device connections.
3Productivity
If the target maximum bit rate is not constrained by the first device's maximum bit rate, then the AUN3 device performance is improved, but the data transmission reliability deteriorates
Solution Approach 1:
The patent applies parameter changes by dynamically determining the target maximum bit rate parameter based on subscription data. The SMF changes the bit rate parameter from a fixed or unrestricted value to a constrained value that is derived from the first device's subscription data. This parameter adjustment ensures that AUN3 device performance is optimized within the reliable bounds of the 5G-RG's data transmission capability.
