Multi-Connection User Plane Offloading by Operator Type
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multi-connectivity networks, there is a need to flexibly control the sharing degree of user plane resources in a second standard network while enabling sharing of a first standard network, particularly due to inconsistent 4G network construction among operators, which is costly and inefficient.
Innovation Solution
A data transmission method that determines the type of a user as a sharing operator or construction operator based on PLMN numbers, and adjusts user plane split policies accordingly, allowing or restricting access to user plane channels in different networks to achieve flexible control over sharing.

1Ease of manufacture
If user plane resources of the second standard network are shared among multiple operators, then construction costs are reduced, but control over resource allocation becomes complex
Solution Approach 1:
The user plane resources are segmented by operator type (construction operator vs. sharing operator). The network device divides the user plane channel into construction operator user plane channel and sharing operator user plane channel, allowing independent control and allocation strategies for each segment while sharing the physical infrastructure.
Solution Approach 2:
Different quality of service and resource allocation policies are applied locally to different operator types. Construction operators receive guaranteed resources with higher priority, while sharing operators receive dynamic resources based on occupancy rates and service types, enabling differentiated control without increasing overall system complexity.
2Productivity
If user plane split is enabled for sharing operators, then resource utilization increases, but network performance degradation occurs due to high occupancy rates
Solution Approach 1:
The user plane split policy is made dynamic based on real-time occupancy rates. When occupancy rate is below the threshold, split is enabled to maximize resource utilization. When occupancy rate exceeds the threshold, split is disabled to prevent performance degradation, allowing the system to adapt to changing network conditions.
Solution Approach 2:
The occupancy rate threshold serves as a dynamic parameter that triggers policy changes. By monitoring the occupancy rate of user plane air interface resources and comparing it against the threshold, the system automatically adjusts the user plane split configuration to balance resource utilization and network performance.
3Ease of operation
If all users share the same user plane resources, then network simplicity is maintained, but flexible control over sharing degree is lost
Solution Approach 1:
The network device implements a universal user plane channel that serves both construction operators and sharing operators. This single user plane channel performs multiple functions: it provides dedicated resources for construction operators while simultaneously enabling shared access for sharing operators, maintaining simplicity while providing flexible control through policy differentiation.
