DAPS Mobility Failure Reporting for Source-Target Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies lack a solution for reporting connection failure information during a Dual Active Protocol Stack (DAPS) mobility procedure, which can result in unreliable connections.
Innovation Solution
A method for transmitting failure information is provided, where a terminal records and reports connection failure information to a network side device, enabling the network to optimize connection configurations and improve reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If connection failure information is not reported during DAPS mobility procedure, then the system maintains simplicity in failure handling, but connection reliability deteriorates
Solution Approach 1:
The patent implements a feedback mechanism where the terminal detects connection failures (source connection failure, target connection failure, or both) and reports failure information to the network side device. This feedback loop enables the network to optimize connection configurations based on actual failure scenarios, thereby improving connection reliability while maintaining manageable system complexity through structured reporting protocols.
2Reliability
If failure information is reported for all connection failures, then connection reliability is improved through optimization, but information processing overhead increases
Solution Approach 1:
The patent segments failure information reporting by connection type, distinguishing between source connection failure, target connection failure, and both failures. This segmentation allows the terminal to report only the specific failure scenario that occurred, reducing unnecessary information processing overhead while ensuring that all critical failure types are captured for network optimization.

AI summary
The present invention provides a method for transmitting failure information and a communications device. The method includes: in a case that failure has occurred on first connection(s) in a dual active protocol stack DAPS mobility procedure, transmitting failure information of at least one of the first connection(s), where the first connection(s) include at least one of the following: a source connection between a terminal and a source cell and a target connection between the terminal and a target cell.
