Problems solved by technology

[0003] When the source cell sends a handover request to the target cell to modify the conditional synchronization reconfiguration content, the target cell replies with a handover request response. The cell cannot notify the target cell that the parameter modification failed
At this time, the target cell may have applied the new configuration, the terminal has not received the parameter modification notification, and is still using the old configuration, and the terminal may not be able to communicate normally due to the inconsistency between the configuration of the terminal and the target cell.

Abstract

The invention provides a condition synchronization reconfiguration method and device. The method comprises the following steps: a first base station sends a switching request message used for requesting to modify conditional synchronization reconfiguration information of a target terminal to a second base station; after receiving a switching request success response message sent by the second base station according to the switching request message, the first base station sends a radio resource control (RRC) connection reconfiguration message to the target terminal; If the first base station fails to successfully notify a target terminal to modify conditional synchronization reconfiguration information according to the RRC connection reconfiguration message, sending a synchronization reconfiguration modification failure notification message to the second base station, so that the second base station recovers to use the conditional synchronization reconfiguration information of the target terminal before modification, or else, the second base station recovers to use the conditional synchronization reconfiguration information of the target terminal before modification. A synchronization reconfiguration modification success notification message is sent to the second base station, so that the second base station synchronizes reconfiguration information by using the modified condition of the target terminal.

Description

technical field [0001] The present application relates to the field of the Internet of Things, and in particular to a conditional synchronization reconfiguration method and device. Background technique [0002] The New Ratio (NR) R16 protocol introduces a conditional synchronization reconfiguration mechanism, which allows the network side to configure multiple target cell resources for the terminal during a conditional synchronization reconfiguration process, and the terminal saves the resources in the conditional synchronization reconfiguration command. configuration, the synchronous reconfiguration procedure is not initiated in the target cell until the conditions configured in the synchronous reconfiguration command are satisfied. When the network configures the conditional synchronous reconfiguration of the terminal to meet the conditional synchronous reconfiguration triggering condition, the network can modify the conditional synchronous reconfiguration information of t...
