5G Session Bit Rate Binding for AUN3 and 5G-RG Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, the session aggregate maximum bit rate (AMBR) of an 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 due to the lack of a binding relationship between AUN3 devices and the 5G-RG.
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 by obtaining and utilizing subscription data through various core network elements like AMF, SMF, and PCF to maintain accurate session management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If the session aggregate maximum bit rate (AMBR) is set independently for each AUN3 device without considering the 5G-RG capability, then the AUN3 device can have higher data transmission capability, but the session establishment fails because the bit rate exceeds the 5G-RG's session establishment capability
Solution Approach 1:
The patent implements a feedback mechanism where the 5G-RG reports its session establishment capability to the core network element. The core network then uses this feedback information to appropriately set the session aggregate maximum bit rate for AUN3 devices, ensuring it does not exceed the 5G-RG's capability while still allowing high data transmission rates within the acceptable range.
Solution Approach 2:
The patent dynamically adjusts the session aggregate maximum bit rate parameter based on the 5G-RG's session establishment capability. Instead of using a fixed or independently determined bit rate, the system changes this parameter to match the actual capability of the 5G-RG, resolving the contradiction between high transmission capability and successful session establishment.
2Reliability
If the session aggregate maximum bit rate is limited by the 5G-RG capability, then the session establishment succeeds, but the data transmission capability of the AUN3 device is reduced
Solution Approach 1:
The patent applies partial action by setting the session aggregate maximum bit rate to match the 5G-RG's session establishment capability rather than the full potential capability of the AUN3 device. This partial limitation ensures successful session establishment while maintaining the highest possible data transmission capability within the constrained range.
3Adaptability or versatility
If there is no binding relationship between AUN3 devices and 5G-RG, then the system has higher flexibility and adaptability, but the session management becomes inaccurate leading to data transmission failures
Solution Approach 1:
The patent introduces a core network element as an intermediary that manages the relationship between AUN3 devices and 5G-RGs. This intermediary collects capability information from 5G-RGs and uses it to make accurate session establishment decisions, thereby maintaining system flexibility while improving session management accuracy through centralized information management.
