Terminal Handover via Conditional Network Device Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, especially during high-speed terminal handovers, the lengthy handover process and uncertainty in handover execution time lead to inefficient use of Contention-Free Random Access (CFRA) resources due to beam variations caused by terminal movement.
Innovation Solution
Conditional information, including communication quality metrics like RSRP, RSRQ, and SINR, is sent by the network device to the terminal to determine the target network device for handover, allowing for optimized resource allocation and reducing CFRA resource wastage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the terminal performs frequent handovers due to high-speed movement, then the terminal can maintain connection with the network, but the handover preparation time becomes insufficient and CFRA resources are wasted due to beam variations
Solution Approach 1:
The network device pre-configures multiple candidate target network devices and their corresponding CFRA resources before the terminal actually needs to handover. This preliminary preparation allows the terminal to immediately access a pre-selected target without waiting for handover preparation, thus increasing execution speed while maintaining reliability through pre-validated targets
Solution Approach 2:
The system dynamically selects among multiple pre-configured candidate target network devices based on real-time conditions. The terminal can choose from several prepared targets rather than being restricted to a single static target, allowing adaptation to beam variations and movement while maintaining handover success
2Ease of operation
If the handover preparation process includes multiple steps, then the handover can be carefully executed, but the handover preparation time becomes too long for high-speed terminals
Solution Approach 1:
Multiple handover parameters including candidate target network devices, CFRA resources, and beam information are pre-configured and stored before handover is needed. This eliminates the need for time-consuming preparation steps during actual handover, reducing preparation time while maintaining operational completeness
Solution Approach 2:
The patent extracts and separates the time-consuming preparation steps from the critical handover execution moment. By pre-configuring all necessary parameters and resources in advance, the system removes preparation delays from the handover process itself, allowing fast execution while preserving thoroughness
