PScell Addition and Change Confirmation via Terminal Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In communication systems, there is a lack of support for reporting successful primary secondary cell (PScell) addition or change, which can lead to failures affecting subsequent transmission services such as dropped calls.
Innovation Solution
A method and apparatus for a terminal device to send indication information to a network-side device upon meeting a reporting trigger condition, indicating successful PScell addition or change, and for the network-side device to receive and obtain this report.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If PScell addition or change is performed without reporting support, then the operation can be executed, but the reliability of the operation is compromised due to lack of confirmation
Solution Approach 1:
The patent implements a feedback mechanism where the terminal device sends indication information to the network-side device to report whether PScell addition or change was successful. The network-side device receives this indication and determines the outcome based on the reported information, creating a closed-loop feedback system that confirms operation success without requiring complex additional reporting procedures.
2Stability of the object's composition
If no reporting mechanism is implemented, then the system remains simple, but service continuity cannot be ensured
Solution Approach 1:
The patent applies preliminary action by having the terminal device prepare and send indication information about PScell addition or change results before any potential service disruption occurs. The network-side device uses this advance information to determine operation success and take preventive measures, ensuring service continuity without requiring complex post-failure recovery procedures.
3Reliability
If indication information is sent to report success, then confirmation opportunity is provided, but communication overhead increases
Solution Approach 1:
The patent extracts only the essential information needed for success confirmation by sending compact indication information from the terminal device to the network-side device. This indication contains only the critical success/failure status without requiring transmission of complete detailed reports, thereby providing reliable confirmation while minimizing communication overhead and information loss.

AI summary
A method for reporting a successful primary secondary cell (PScell) addition or change report, performed by a terminal device, includes: sending indication information to a network-side device after a reporting trigger condition is met. The indication information indicates that the terminal device has the successful PScell addition or change report.
