UE Access Leg Selection During Data Replication Pause
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, the suspension of data duplication without configuring a primary access leads to uncertainty about which access leg to use for data transmission, causing time sequence issues and reducing data transmission reliability.
Innovation Solution
A method and apparatus for setting and canceling an access leg in response to data duplication suspension and resumption messages, ensuring consistent use of a unified access leg for data transmission, thereby aligning the access settings of the UE and network device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If data duplication is suspended without configuring a primary access, then network resource utilization is improved, but data transmission reliability deteriorates due to uncertainty about which access leg to use
Solution Approach 1:
The patent applies preliminary action by pre-configuring access leg identification information before data duplication suspension. When data duplication is suspended, the UE and network device can immediately determine which access leg to use based on the pre-configured identification information, avoiding uncertainty and ensuring reliable data transmission without compromising network resource utilization.
2Adaptability or versatility
If data duplication is suspended without configuring a primary access, then flexibility in access selection is improved, but time sequence consistency deteriorates causing out-of-order service sequences
Solution Approach 1:
The patent implements feedback by establishing a mechanism where the UE and network device share and confirm access leg identification information. This feedback loop ensures both sides have consistent understanding of which access leg to use, maintaining time sequence consistency while preserving access selection flexibility through the configurable identification information.
3Adaptability or versatility
If access settings are not aligned between UE and network device after data duplication suspension, then adaptability is improved, but communication reliability deteriorates due to setting differences
Solution Approach 1:
The patent introduces access leg identification information as an intermediary element that mediates between the UE and network device. This identification information serves as a common reference that both sides use to align their access settings, ensuring communication reliability while maintaining adaptability through the configurable nature of the identification information.

AI summary
Embodiments of the present disclosure provide an information processing method and apparatus, a communication device, and a storage medium. The information processing method executed by a user equipment (UE) may comprise: setting a default access mode in response to receiving a data transmission replication pause message and not configuring a primary access mode, the default access mode being one of a plurality of access modes currently used by the UE, and the default access mode being used for pausing data transmission after data transmission replication according to the data transmission replication pause message; and canceling the setting of the default access mode in response to receiving a data transmission replication resume message.
