Radio Bearer Invalidation Handling for Direct and Indirect Paths
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems fail to effectively record and report information about the invalidation of both direct and indirect paths when both are used simultaneously, leading to inadequate network optimization and potential communication interruptions.
Innovation Solution
A method and device for wireless communications that detect the invalidation of a first bearer associated with a cell group, execute a specific operation set based on the bearer type, and transmit corresponding information to facilitate network optimization, including re-establishing or releasing RLC entities and storing invalidation information in a state variable.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a UE uses both direct path and indirect path simultaneously, then communication reliability is improved, but failure information recording capability deteriorates
Solution Approach 1:
The patent segments the failure information recording mechanism by separating direct path failure recording from indirect path failure recording. When direct path fails, the UE records failure information for the direct path; when indirect path fails, the UE records failure information for the indirect path. This segmentation allows both paths to be monitored independently while maintaining comprehensive failure information recording capability.
Solution Approach 2:
The patent implements preliminary action by having the UE prepare and maintain failure information recording mechanisms for both direct and indirect paths in advance. The UE is configured to record failure information for the direct path and separately for the indirect path, ensuring that when failures occur, the information is already prepared to be recorded without disrupting the simultaneous operation of both paths.
2Manufacturing precision
If the UE records failure information for direct path only, then network optimization for direct path is improved, but overall network optimization capability deteriorates
Solution Approach 1:
The patent applies universality by making the failure information recording mechanism applicable to both direct path and indirect path. The UE is configured to record failure information for the direct path and also record failure information for the indirect path, allowing the same recording mechanism to serve multiple paths and enhance overall network optimization capability across different communication scenarios.
3Duration of action of stationary object
If the indirect path is used as backup, then communication continuity is improved, but failure information availability for optimization deteriorates
Solution Approach 1:
The patent segments the failure information recording by creating separate recording mechanisms for direct path and indirect path failures. The UE records failure information for the direct path and separately records failure information for the indirect path, ensuring that failure information is available for both paths even when one path is used as backup for communication continuity.

AI summary
The present application discloses a method and a device for wireless communications, including detecting invalidation of a first bearer; the first bearer being associated with a first cell group; and as a response to the action of detecting invalidation of a first bearer, executing a first operation set, the first operation set being related to a type of the first bearer; and transmitting first information as a response to the action of detecting invalidation of a first bearer; the first information being used to indicate the invalidation of the first bearer; and transmitting a second message as a response to all conditions in a first condition set being satisfied; the second message indicating existence of available information. The present application helps network optimization by detecting invalidation of the first bearer and executing the first operation set, thus enhancing the communication reliability and avoiding interruption.
