Conditional PSCell Change Thresholds for UE Processing Capacity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing Conditional PSCell Change (CPC) mechanism in dual connectivity often configures too many potential PSCells, exceeding the processing capacity of the User Equipment (UE), leading to potential communication interruptions and interference.
Innovation Solution
Implement a configuration method to limit the number of CPCs configured by both the Master Node (MN) and Secondary Node (SN) based on a predefined threshold, ensuring the total number does not exceed the UE's capacity, thereby optimizing mobility performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple potential PSCells are configured for the UE, then mobility performance and handover reliability are improved, but the processing capacity of the UE is exceeded
Solution Approach 1:
The patent introduces a maximum number parameter to limit the quantity of potential PSCells configured for the UE. By changing the parameter of configuration quantity from unlimited to bounded, the system resolves the contradiction between improving handover reliability through multiple configurations and avoiding UE processing overload.
2Reliability
If the number of CPCs is increased to improve mobility performance, then connectivity reliability is improved, but communication interruptions increase due to exceeding UE capacity
Solution Approach 1:
The patent applies a maximum number constraint parameter to control the quantity of CPC configurations. This parameter change ensures that the system maintains optimal connectivity reliability while preventing communication interruptions caused by exceeding UE processing capacity, thus resolving the productivity-reliability contradiction.

AI summary
A configuration method and apparatus for Conditional Primary Secondary Cell Group Cell (PSCell) Change (CPC) in dual connectivity, a storage medium, a base station, and a terminal are provided. The method includes: for configuring the CPC for a User Equipment (UE), determining whether a configuration threshold has been received from a master base station, wherein the configuration threshold is a number threshold of CPCs configurable by a secondary base station; and determining a number of the CPCs configurable by the secondary base station based on the number threshold, in response to the configuration threshold having been received from the master base station, wherein the number of the CPCs configurable by the secondary base station is less than or equal to the configuration threshold.
