Dynamic Split Bearer Mechanism for 5G Dual-Connection Power Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G dual-connection networks, user equipment must continuously monitor and manage data transmission across both 4G and 5G base stations, leading to high power consumption and potential data loss due to inappropriate data distribution ratios between the two networks.
Innovation Solution
A dynamic split bearer mechanism is introduced, allowing for selective connection of user equipment to both base stations, with a processor determining remaining load and demand to activate or deactivate data splitting and adjust the data distribution ratio dynamically, ensuring timely processing and minimizing data loss.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If user equipment continuously monitors and manages data transmission across both 4G and 5G base stations, then data transmission reliability is improved, but power consumption increases
Solution Approach 1:
The base station automatically monitors data packet transmission status and manages the split bearer configuration without requiring user equipment to continuously monitor both base stations. The base station autonomously determines whether to activate or deactivate split bearer based on transmission reliability, thereby reducing power consumption at the user equipment while maintaining reliable data transmission.
2Productivity
If data is transmitted through both 4G and 5G base stations simultaneously, then transmission speed is improved, but data loss risk increases due to inappropriate data distribution ratios
Solution Approach 1:
The base station monitors the transmission status of data packets and provides feedback to dynamically adjust the data distribution ratio between 4G and 5G base stations. When transmission reliability is insufficient, the base station adjusts the split bearer configuration to prevent data loss, thereby maintaining both high transmission speed and data reliability.
3Productivity
If split bearer is always activated for dual-connection, then data transmission capacity is improved, but system complexity increases
Solution Approach 1:
The split bearer configuration is made dynamic rather than static. The base station activates or deactivates the split bearer based on real-time transmission reliability requirements and load conditions. This dynamic adjustment allows the system to maintain high data transmission capacity when needed while reducing complexity when single-connection suffices.

AI summary
A base station and an adjustment method for data transmission are provided. User equipment is selectively connected to two base stations at the same time. In the method, a remaining load amount is determined. A load demand amount required for a to-be-transmitted data bearer in the data bearer is determined. It is determined that a portion of the data packets corresponding to the to-be-transmitted data bearer is split, according to a comparison result between the remaining load amount and the load demand amount, to the second base station for transmission. A transmission ratio of the data packets split to the base station to those split to the second base station is determined according to a ratio of packet loss of the base station to the second base station. Accordingly, electric power of the user equipment can be saved, data loss can be reduced, and data can be converged effectively.
