Multi-Connectivity User-Plane Splitting for 4G/5G Sharing Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multi-connectivity networks, there is a challenge in realizing flexible control of the sharing degree of the user plane of the second standard network while enabling the sharing of the first standard network, particularly due to inconsistent 4G network construction progress among operators.
Innovation Solution
A data transmission method that determines the type of a terminal's user in a multi-connectivity network, with policies to either split or not split user plane data across different standard networks based on user type and occupancy rates of air interface resources, allowing for flexible control of user plane sharing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If user plane data is split across multiple standard networks (4G and 5G), then transmission rate is improved, but control over sharing degree becomes difficult
Solution Approach 1:
The patent implements dynamic control of user plane split policies by introducing a switch parameter that can be dynamically adjusted based on user type and network conditions. The network device can flexibly enable or disable user plane splitting for different terminals, allowing real-time adaptation of sharing degree while maintaining high transmission rates when needed.
Solution Approach 2:
The patent applies different user plane split policies to different users based on their types (sharing operator users vs. construction operator users). By customizing the split policy for each user type, the system achieves flexible control over sharing degree at the user level while maintaining overall high transmission performance.
2Quantity of substance
If 5G network is shared among multiple operators, then construction cost is reduced, but network performance control becomes complex
Solution Approach 1:
The patent simplifies network performance control by changing the parameter representation from complex multi-operator configurations to a simple user type classification system. By categorizing users into two types (sharing operator and construction operator) and applying corresponding split policies, the system achieves easy control over shared 5G network performance while maintaining cost-effective multi-operator deployment.
3Productivity
If user plane split is enabled for all users, then transmission efficiency is improved, but resource occupancy control becomes difficult
Solution Approach 1:
The patent implements localized control of user plane splitting by applying different policies to different user types. Construction operator users receive split-enabled policies for high transmission efficiency, while sharing operator users receive split-disabled policies to control resource occupancy. This user-specific approach maintains overall transmission efficiency while ensuring reliable resource control.
