Split Bearer Control With Dynamic Path Activation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile communications systems, such as 5G systems, using dual connectivity architecture often configure only two transmission paths for a radio bearer with a data duplication function, which may not meet high reliability requirements.
Innovation Solution
A split bearer control method that configures a target split bearer with N transmission paths (where N is greater than 2) and allows the terminal to activate or deactivate a data duplication function in response to split bearer indication signaling sent by the network-side device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If only two transmission paths are configured for a radio bearer with data duplication function, then the device complexity is reduced, but the reliability of data transmission cannot satisfy high requirement
Solution Approach 1:
The patent applies dynamics by making the number of transmission paths configurable and adjustable. Instead of being fixed at two, the system allows dynamic configuration of N transmission paths (N>2) based on reliability requirements, while maintaining the ability to deactivate duplication when only two paths are needed, thus balancing complexity and reliability needs.
Solution Approach 2:
The patent changes the parameter of transmission path quantity from a fixed value (2) to a variable parameter (N). This allows the system to adapt the number of transmission paths according to different reliability requirements, resolving the contradiction between having more paths for higher reliability and maintaining simpler device architecture.
2Reliability
If data duplication function is activated with multiple transmission paths, then the reliability of data transmission is improved, but the resource utilization is reduced
Solution Approach 1:
The patent applies dynamics by enabling the data duplication function to be activated or deactivated based on actual network conditions and reliability requirements. When high reliability is needed, duplication is activated with multiple paths; when resources are constrained, duplication can be deactivated, thus dynamically balancing reliability and resource utilization.
Solution Approach 2:
The system can periodically assess network conditions and reliability requirements to determine when to activate or deactivate the data duplication function. This periodic evaluation allows the system to optimize resource utilization by enabling duplication only when necessary, rather than maintaining it continuously.
3Reliability
If the number of transmission paths is increased for a split bearer, then the reliability of data transmission is enhanced, but the device complexity increases
Solution Approach 1:
The patent makes the transmission path configuration dynamic by allowing the network to signal the terminal about the number of paths (N) without requiring complex local configuration. The terminal receives indication information from the network side, simplifying the configuration process while still enabling multiple transmission paths for enhanced reliability.
Solution Approach 2:
The system implements feedback mechanisms where the network side provides indication signaling to the terminal about the number of transmission paths and data duplication configuration. This feedback approach reduces terminal complexity by having the network manage configuration details while still achieving high reliability through multiple paths.
