Data Gateway User Data Marking for 5GNR and Non-5GNR Access Nodes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication networks, particularly hybrid 5GNR/LTE networks, face challenges in efficiently determining whether user devices are communicating through 5GNR or LTE access points and tracking uplink and downlink user data, leading to suboptimal resource allocation and network capacity management.
Innovation Solution
A wireless communication system that includes a 5GNR access point and a non-5GNR access point, where a data gateway marks and tracks user data as either 5GNR or non-5GNR, enabling network controllers to differentiate and manage data usage effectively, thereby optimizing resource allocation and network performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If hybrid 5GNR/LTE networks use both 5GNR access nodes and LTE access nodes to serve dual-radio user devices, then network capacity and service versatility are improved, but the ability to determine whether user devices are communicating through 5GNR or LTE access points deteriorates
Solution Approach 1:
The patent segments user data into distinct 5GNR user data and non-5GNR user data streams, with separate bearers for each type. This segmentation allows the network to track and manage data usage for each access node type independently, resolving the information loss problem while maintaining hybrid network capabilities
Solution Approach 2:
The patent introduces an intermediary function (UE policy function or network controller) that receives data usage information from both 5GNR and LTE access nodes and provides unified policy control. This intermediary consolidates tracking information and enables intelligent determination of which access node type is being used
2Device complexity
If the network uses simple and rigid bearer setup for 5GNR and LTE access nodes, then device complexity is reduced, but the efficiency and effectiveness of determining data exchange paths deteriorates
Solution Approach 1:
The patent introduces dynamic bearer setup and modification capabilities that allow the network to adaptively create separate bearers for 5GNR and non-5GNR data based on real-time network conditions and user device behavior. This dynamic approach maintains simple rigid bearers when not needed while enabling efficient tracking when hybrid operation is active
3Device complexity
If the network cannot intelligently track uplink and downlink user data for dual-radio user devices, then system simplicity is maintained, but resource allocation optimization deteriorates
Solution Approach 1:
The patent implements feedback mechanisms where access nodes report data usage information to network controllers, which then provide policy decisions back to the network. This feedback loop enables intelligent resource allocation and throttling based on actual data exchange patterns through 5GNR or LTE access points

AI summary
A wireless communication system serves User Equipment (UE) over a Fifth Generation New Radio (5GNR) access point and a non-5GNR access point. The non-5GNR access point exchanges attachment signaling with the UE and exchanges network signaling with a network controller. The network controller exchanges bearer signaling with a data gateway. The data gateway marks Downlink (DL) user data as non-5GNR DL user data and transfers the non-5GNR DL user data to the non-5GNR access point. The data gateway marks additional DL user data as 5GNR DL user data and transfers the 5GNR DL user data to the 5GNR access point. The non-5GNR access point receives and wirelessly transfers the non-5GNR DL user data to the UE. The 5GNR access point receives and wirelessly transfers the 5GNR DL user data to the UE. The data gateway tracks the transferred amount of the non-5GNR DL user data and 5GNR DL user data.
