Problems solved by technology

[0005] However, in the prior art, only the cells in the cell list are measured, and because the search cycle is often larger, for example, greater than the SMTC cycle, some cells with strong signals cannot be searched all the time, so they will not be measured. measurement usage, resulting in an impact on communication quality

Embodiment Construction

[0026] In the prior art, a mobile device needs to be handed over between multiple cells. refer to figure 1 , figure 1 It is a schematic diagram of a working scene of a cell handover method in the prior art.

[0027] exist figure 1 In the shown cell handover method, there are SMTC search windows and SMTC measurement windows, where the search period of the SMTC search window is generally longer than the measurement period of the SMTC measurement window.

[0028] In the prior art, the SSB of each adjacent cell is usually searched according to the search cycle configured by the network, and then the searched cell is added to the cell list, and then the cells in the cell list are measured according to the SMTC cycle configured by the network, such as measuring RSRP The parameter value for the parameter.

[0029] For example, in the process of measuring cell 1, cell 2, and cell 3, part of the SSB of cell 1 and the SSB of cell 3 can be measured. However, for cell 2, due to the re...

Abstract

A cell switching method and device, a storage medium, and a terminal, the method comprising: determining an SMTC measurement window; searching for SSBs of adjacent cells in the SMTC measurement window, and simultaneously searching for SSBs of each search cell that has found an SSB Preset parameter measurement to obtain the parameter value of the search cell; if the search cell is not included in the cell list, determine whether to add the search cell to the cell list; The cell with the largest average value of parameter values ​​in the cell list is determined to determine whether to perform handover. The solution of the invention can improve the switching effect.

Description

technical field [0001] The present invention relates to the technical field of communications, and in particular to a cell switching method and device, a storage medium, and a terminal. Background technique [0002] In 3GPP's RAN1 research on New Radio (NR), the concept of SS block based RRM measurement timing configuration (SMTC) has been proposed, including the measurement period (Period) of the SMTC measurement window , time domain offset (Offset) and duration (Duration) and other information. [0003] In 3GPP's research on NR, the cycle of the base station sending a synchronization signal block (SS block, SSB) can be different, that is, the cycle of the SMTC measurement window can also be different, for example, the cycle of the SMTC measurement window The measurement period may be one of the following optional values: 5ms, 10ms, 20ms, 40ms, 80ms, 160ms. [0004] In the prior art, a mobile device needs to be handed over between multiple cells. Usually search the SSBs ...
