Selective Cell Group Activation in MR-DC Without Reconfiguration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication technologies in Multi-Radio Dual Connectivity (MR-DC) do not clearly specify the communication behavior of terminals when selectively activating multiple cell groups, leading to increased signaling overhead and interruption duration during cell group changes.
Innovation Solution
A method for performing cell group activation and deactivation based on configuration information, allowing selective activation of cell groups without reconfiguration or reinitialization, which includes receiving and applying configuration information for cell group activation and deactivation processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cell group reconfiguration or reinitialization is performed during cell group changes, then communication reliability is improved, but signaling overhead increases and interruption duration increases
Solution Approach 1:
The terminal performs cell group activation or deactivation based on pre-configured configuration information without requiring reconfiguration or reinitialization. The configuration information is prepared in advance by the network device, allowing the terminal to switch cell groups immediately when activation conditions are met, thus avoiding interruption delays while maintaining communication reliability
Solution Approach 2:
The patent extracts the essential configuration information needed for cell group activation and separates it from the complete reconfiguration process. By using a subset of configuration information (activation configuration information) rather than full reconfiguration, the patent reduces signaling overhead and processing time while maintaining the necessary communication reliability
2Reliability
If cell group reconfiguration or reinitialization is performed during cell group changes, then communication reliability is improved, but signaling overhead increases
Solution Approach 1:
The patent extracts only the necessary configuration information for cell group activation from the complete reconfiguration set. The activation configuration information includes only essential parameters needed for activation, excluding redundant configuration data, thereby reducing signaling overhead while maintaining communication reliability
Solution Approach 2:
The network device provides activation configuration information in advance, containing pre-configured parameters needed for cell group activation. This preliminary provision of configuration information eliminates the need for extensive signaling during the actual activation process, reducing signaling overhead while ensuring reliable communication
3Productivity
If multiple cell groups are activated simultaneously, then system capacity is improved, but device complexity increases
Solution Approach 1:
The terminal autonomously determines whether to activate or deactivate cell groups based on pre-configured activation conditions and current system state, without requiring complex network control for each activation decision. This self-service mechanism simplifies terminal complexity while enabling multiple cell groups to be activated simultaneously, improving system capacity
Solution Approach 2:
The patent implements dynamic cell group activation where the terminal can selectively activate or deactivate cell groups based on real-time conditions such as activation conditions being met or not met. This dynamic approach allows flexible management of multiple cell groups, improving system capacity while keeping terminal complexity manageable through condition-based automation
Data Source
AI summary
