example 1

[0361] Example 1: Configure only one timer and / or one counter, and start it when receiving the first RRC message containing the configuration information of the target handover cell, for example, when configuring a conditional handover configuration message

[0362] Step 111: The serving base station gNB1 cell1 configures the measurement configuration for the UE, including the measurement configuration of event 1 and / or the measurement of event 2;

[0363] Wherein, the measurement of event 1 is used for the serving base station to select a pre-configured target handover cell for the conditional handover, and the measurement of event 2 is used for the UE to trigger the handover.

[0364] Step 112: The UE performs measurement according to the network configuration, and the measurement of a cell meets event 1, triggering the UE to report a measurement report.

Abstract

The present invention provides a cell handover processing method, device and equipment, which solves the problem of large data interruption and delay caused by the UE directly entering an idle state or triggering the reestablishment process of other cells after the UE fails to trigger the handover. The method includes: acquiring configuration information of a target handover cell and at least one of the following information: valid time of the cell configuration information and number of valid accesses; within the valid time of the cell configuration information and / or the number of valid accesses, according to the The target handover cell configuration information is used to perform cell handover. In the present invention, after the terminal handover fails, the effective time and / or the number of effective access times of the cell configuration information can be used to make multiple access attempts according to the target handover cell configuration information, thereby avoiding the terminal directly entering the idle state or triggering the re-establishment of other cells. process to reduce data interruption delay.

Description

technical field [0001] The present invention relates to the technical field of communications, and in particular to a cell handover processing method, device and equipment. Background technique [0002] The 5G new air interface (NR) standard Rel-16 version technology introduces the concept of conditional handover (conditional handover), which is a method of providing one or more pre-configured target handover cells for the terminal UE to improve the reliability of handover . However, at present, if the traditional handover process fails, the UE will trigger a reestablishment process to restore the radio resource control (Radio Resource Control, RRC) connection. After configuring multiple preconfigured handover cells required for conditional handover, when a preconfigured cell meets the handover conditions, the UE will perform cell handover to the target preconfigured cell. If the UE fails to switch to the target handover cell, Considering that there are still other pre-con...
