Handover State Information Reporting for Network Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional technologies struggle to effectively report state information of handover procedures involving multiple attempts to multiple candidate cells, failing to meet the configuration requirements of network devices.
Innovation Solution
A method for reporting state information, where a terminal transmits information including random access procedure state, connection failure information, and RLF information to a network device, enabling the network device to optimize configurations based on this information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conventional handover reporting methods are used, then the reporting process is simple, but the network device cannot obtain comprehensive state information for complex handover procedures involving multiple candidate cells
Solution Approach 1:
The patent segments handover state information into distinct categories including random access procedure state information, connection failure information, and RLF information. Each category is separately reported to the network device, ensuring comprehensive coverage of complex handover procedures involving multiple candidate cells without overwhelming the reporting mechanism.
Solution Approach 2:
The patent introduces a new dimension for information reporting by adding multiple types of state information (random access procedure state, connection failure state, RLF state) beyond traditional handover reporting. This multi-dimensional approach enables the network device to comprehensively analyze complex handover scenarios with multiple candidate cells.
2Reliability
If comprehensive state information is reported, then the network device can optimize configurations, but the reporting overhead increases
Solution Approach 1:
The patent extracts only the essential state information elements needed for network device configuration optimization: random access procedure state information, connection failure information, and RLF information. By selectively extracting and reporting only these critical parameters, the patent reduces reporting overhead while maintaining the reliability needed for effective configuration optimization.
3Reliability
If multiple handover attempts are performed, then the handover success rate improves, but the difficulty of reporting state information increases
Solution Approach 1:
The patent divides state information reporting into distinct segments corresponding to each handover attempt and candidate cell. Each segment includes specific state information (random access procedure state, connection failure state, RLF state) for that particular attempt, making it easier to track and report results of multiple handover attempts systematically.
Solution Approach 2:
The patent prepares and structures state information in advance during the handover execution process, organizing random access procedure state information, connection failure information, and RLF information as they occur. This preliminary organization simplifies the subsequent reporting process even when multiple handover attempts are performed.
Data Source
AI summary
A method for reporting state information, a terminal, and a network device are provided. The method for reporting state information includes transmitting state information, by the terminal, of a handover procedure to the network device, where the state information of a handover procedure includes at least one of the following: random access procedure state information corresponding to a handover target cell of the handover procedure; connection failure information corresponding to a handover target cell of the handover procedure; and RLF information in the handover procedure.
