User Equipment Cell Management With Preconfigured Activation States
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems face challenges in efficiently managing the selective activation of cells and/or cell groups for user equipment (UE) without causing significant signaling overhead and interruption during changes in cell group connections.
Innovation Solution
A cell management method and apparatus that allows user equipment (UE) to obtain configuration information from a network device, determine the initial configuration state of candidate cells and/or cell groups, and manage them accordingly, enabling selective activation without the need for reconfiguration by the network device.

Engineering Contradiction Analysis
1Ease of operation
If the network device reconfigures candidate cells and/or cell groups for selective activation, then the UE can perform cell management, but signaling overhead increases
Solution Approach 1:
The network device pre-configures candidate cells and cell groups with their initial activation states before the UE needs to perform selective activation. This preliminary configuration stores the activation state information in advance, so when the UE needs to activate or deactivate cells, it can directly use the pre-stored configuration without requiring additional signaling exchanges, thereby reducing signaling overhead while maintaining full cell management capability
Solution Approach 2:
The UE stores configuration information of candidate cells and cell groups locally, creating a local copy of the network device's configuration. This local copy includes the initial activation states and can be used for selective activation without continuous network communication, reducing the need for repeated signaling while ensuring the UE has the necessary configuration data for cell management operations

AI summary
A cell management method is performed by a user equipment (UE). The method includes: obtaining configuration information of at least one of at least one candidate cell or at least one candidate cell group configured by a network device; determining an initial configuration state of at least one of a candidate cell or a candidate cell group, wherein the initial configuration state comprises at least one of a configured initial activation state of the candidate cell, a configured initial activation state of the candidate cell group, an initial cell type, or an initial cell group type; and managing at least one of the candidate cell or the candidate cell group based on the configuration information and the initial configuration state.
