Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing network systems face challenges in configuring conditional handover (CHO) and conditional primary-secondary cell addition/change (CPAC) due to exceeding the measurement capabilities of user equipment (UE), leading to inefficiencies in dual connectivity.
Innovation Solution
A method and apparatus that involve a first network device receiving and processing configuration information related to CHO and CPAC, and sending it to a terminal, while also requesting and interacting with second network devices to manage candidate cell lists and measurement capabilities to align with UE capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the network configures up to eight candidate target cells for CHO and each target cell is configured with a maximum of eight candidate SNs, then the coverage and connectivity options are improved, but the measurement capability of the UE is exceeded
Solution Approach 1:
The patent segments the configuration process into two stages: first configuring CHO candidate cells, then conditionally configuring CPAC candidate SNs based on whether CHO is executed. This segmentation allows the network to provide comprehensive connectivity options (8 candidate cells × 8 candidate SNs) while the UE only needs to perform measurements on CHO candidate cells, avoiding the need to measure all possible cell-SN combinations simultaneously.
Solution Approach 2:
The patent performs preliminary configuration of CHO candidate cells before configuring CPAC candidate SNs. The network first provides CHO configuration information to the UE, and only after the UE successfully executes CHO does the network subsequently provide CPAC configuration information. This preliminary action ensures that the UE's measurement capabilities are not overwhelmed by configuring all possible measurements at once.
2Productivity
If the network configures CHO and CPAC mechanisms simultaneously, then the dual connectivity efficiency is improved, but the UE measurement capability is exceeded
Solution Approach 1:
The patent implements a dynamic configuration approach where CPAC configuration is provided conditionally based on CHO execution status. The network dynamically adjusts the measurement configuration burden on the UE by only requiring measurements on CHO candidate cells initially, and only afterward requiring measurements on CPAC candidate SNs if CHO was successfully executed. This dynamic approach maintains high dual connectivity efficiency while adapting to the UE's actual measurement capabilities at each stage.
3Reliability
If the network provides comprehensive configuration information for both CHO and CPAC, then the handover reliability is improved, but the information processing overhead increases
Solution Approach 1:
The patent uses preliminary action by first providing CHO configuration information to establish basic handover reliability, then conditionally providing CPAC configuration information afterward to enhance dual connectivity. This staged approach ensures handover reliability is maintained through comprehensive CHO configuration, while CPAC configuration is added only when needed, reducing the total quantity of configuration information the UE must process simultaneously.
