Technical Field

Background
The concept of SS block based measurement timing configuration (SMTC) based on a sync signal block has been proposed in the RAN1 research of 3GPP on New Radio (NR), including information of a measurement Period (Period), time Offset (Offset), and Duration (Duration) of a SMTC measurement window.
In the research of NR by 3GPP, periods of Synchronization Signal Blocks (SSBs) transmitted by base stations may be different, that is, periods of the SMTC measurement windows may also be different, for example, a measurement period of the SMTC measurement window may be one of the following alternative values: 5ms, 10ms, 20ms, 40ms, 80ms, 160 ms.
In the prior art, there are situations where a mobile device needs to be handed over between multiple cells. Generally, SSBs of neighboring cells are searched according to a search period configured by a network, then the searched cells are added to a cell list, and further, the cells in the cell list are measured according to an SMTC period configured by the network, for example, a parameter value of a Reference Signal Receiving Power (RSRP) parameter is measured. Further, when the measurement result of the preset times is continuously lower than the preset intensity threshold value, it can be determined that the cell signal is too weak to be applicable, and then the cell signal is deleted from the list.
However, in the prior art, only the cells in the cell list are measured, and since the search period is often large, for example, greater than the SMTC period, some cells with strong signals cannot be searched all the time, and the cells cannot be measured and used, which affects the communication quality.

Detailed Description
In the prior art, there are situations where a mobile device needs to be handed over between multiple cells. Referring to fig. 1, fig. 1 is a schematic view of a working scenario of a cell switching method in the prior art.
In the cell handover method shown in fig. 1, there are an SMTC search window and an SMTC measurement window, where the search period of the SMTC search window is generally larger than the measurement period of the SMTC measurement window.
In the prior art, SSBs of neighboring cells are generally searched according to a search period configured by a network, then the searched cells are added to a cell list, and further, the cells in the cell list are measured according to an SMTC period configured by the network, for example, a parameter value of an RSRP parameter is measured.
For example, in the process of measuring the cell 1, the cell 2, and the cell 3, a part of the SSB of the cell 1 and the SSB of the cell 3 may be measured, however, for the cell 2, since the search period is relatively long (i.e., the search frequency is relatively small) and the search frequency is not adapted to the signal frequency of the cell 2, the signal of the cell 2, although relatively strong, cannot be searched all the time, and there is no chance to add the cell 2 into the cell list, so that the cell 2 has no measurement and measurement report all the time, and even if the signal quality of the cell 2 is good, the handover to the cell 2 is not performed during the handover.
Further, in the prior art, there is also a setting to delete weak-signal cells from the list. Specifically, when the measurement result of the preset number of times is continuously lower than the preset intensity threshold, it may be determined that the cell signal is too weak to be applicable, and then the cell signal may be deleted from the list.
For example, if the signal period of the cell 3 is greater than the measurement period of the SMTC measurement window, it is easy to mistakenly consider that the signal is weak in a single signal period of the cell 3, and mistakenly delete the cell 3 in the cell list, so that only the cell 1 is in the cell list, which may actually be the case that the signal quality of the cell 3 is good, but the cell 3 cannot be subsequently switched to the cell 3 due to the mistaken deletion.
That is, in the prior art, there are two problems: 1. only the cells in the cell list are measured, and as the search period is often large, for example, greater than the SMTC period, some cells with strong signals cannot be searched all the time, and thus the cells cannot be measured and used, which affects the communication quality; 2. under the condition that the number of the cells in the cell list does not reach the upper limit, the cells in the cell list are deleted, so that the selectable cells are too few, and the switching cannot be performed in serious cases.
The inventor of the present invention has found through research that in the prior art, there are two windows: the SMTC search window and the measurement window, and the search frequency of the search window is usually lower than the measurement frequency of the SMTC measurement window, so that some cells can not be searched all the time, but the search using the measurement window can increase the chance of being searched.
In the embodiment of the invention, an SMTC measurement window is determined; searching SSBs of adjacent cells in the SMTC measuring window, and measuring preset parameters of each searched cell in which the SSBs are searched to obtain parameter values of the searched cells; determining whether to add the search cell to the cell list if the search cell is not included in the cell list; and when cell switching is needed, determining whether to switch or not according to the cell with the largest average value of the parameter values in the cell list. By adopting the scheme, the SMTC measuring window is adopted for searching, and because the measuring frequency of the SMTC measuring window is usually higher than the searching frequency of the searching window, compared with the searching by adopting the searching window in the prior art, the method can effectively increase the opportunity that the adjacent cells are searched, reduce the possibility that some cells with strong signals can not be searched all the time, and improve the switching effect.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
Referring to fig. 2, fig. 2 is a flowchart of a cell handover method according to an embodiment of the present invention. The cell switching method may include steps S21 to S24:
step S21: determining an SMTC measurement window;
step S22: searching SSBs of adjacent cells in the SMTC measuring window, and measuring preset parameters of each searched cell in which the SSBs are searched to obtain parameter values of the searched cells;
step S23: determining whether to add the search cell to the cell list if the search cell is not included in the cell list;
step S24: and when cell switching is needed, determining whether to switch or not according to the cell with the largest average value of the parameter values in the cell list.
In a specific implementation of step S21, the period of the SMTC measurement window may be different, for example, the measurement period of the SMTC measurement window may be one of the following alternative values: 5ms, 10ms, 20ms, 40ms, 80ms, 160 ms.
Further, the step of determining the SMTC measurement window may comprise: determining SMTC measurement periods of a plurality of SMTC raw measurement windows; and taking an SMTC original measurement window with the minimum SMTC measurement period as the SMTC measurement window.
Specifically, the SMTC measurement period of the SMTC raw measurement window may be configured by the network side. More specifically, there may be multiple SMTCs at the same frequency, for example two: SMTC1 and SMTC2, and the SMTC1 can be the only one in pilot frequency.
In the embodiment of the present invention, when there are multiple SMTCs, the SMTC original measurement window with the smallest SMTC measurement period may be used as the SMTC measurement window, and by adopting a smaller measurement period, the method helps to further increase the chance that the cell is searched.
In the specific implementation of step S22, the SMTC measurement window searches for SSBs of neighboring cells, and when there is an SSB in a certain cell, the SSB can be searched; and then measuring preset parameters of each search cell of the searched SSB to obtain parameter values of the search cells.
Specifically, the preset parameter may be Reference Signal Received Power (RSRP). The RSRP is one of key parameters that can represent the radio signal strength in the LTE network and the physical layer measurement requirement, and is an average value of received signal power on all Resource Elements (REs) that carry reference signals within a certain symbol.
Referring to fig. 3, fig. 3 is a schematic view of a working scenario of a cell switching method according to an embodiment of the present invention.
In the cell handover method shown in fig. 3, SSBs of neighboring cells are searched according to a measurement period configured by the network. Since the search period of the SMTC search window is usually larger than the measurement period of the SMTC measurement window, the SSBs of cell 1, cell 2 and cell 3 can be searched.
With continued reference to fig. 2, in the specific implementation of step S22, by using the SMTC measurement window for searching, since the measurement frequency of the SMTC measurement window is usually higher than the search frequency of the search window, compared with the search window used in the prior art for searching, the probability that neighboring cells are searched can be effectively increased, the probability that some cells with strong signals can not be searched all the time is reduced, and the handover effect is improved.
In an implementation of step S23, if the search cell is not included in the cell list, it is determined whether to add the search cell to the cell list.
Referring to fig. 4, fig. 4 is a flowchart of an embodiment of step S23 in fig. 2. The step of determining whether to add the search cell to the cell list may include steps S41 through S42, each of which is described below.
In step S41, if the number of existing cells included in the cell list does not reach a preset upper limit, the search cell is added to the cell list.
In the embodiment of the present invention, when it is determined that the number of existing cells included in the cell list does not reach the preset upper limit, the selectivity when cell handover is required can be improved by adding the search cell to the cell list.
In step S42, if the number of existing cells included in the cell list reaches a preset upper limit, each search cell is compared with the existing cells in turn, and a cell with a higher parameter value is reserved in the cell list.
In the embodiment of the present invention, when it is determined that the number of existing cells included in the cell list reaches the preset upper limit, a cell more worthy of being retained to the cell list may be determined through a comparison step.
Referring to fig. 5, fig. 5 is a flowchart of an embodiment of step S42 in fig. 4. The step of comparing each search cell with the existing cell in turn and reserving a cell with a higher parameter value in the cell list may include steps S51 to S52, which are described below.
In step S51, the average value of the parameter values of each existing cell in the cell list is determined and sorted.
Wherein the average value of the parameter value of each existing cell may be an average value of the parameter values in a past preset time period, so that the signal level of the existing cell in a certain time period can be reflected.
In step S52, the parameter value of each search cell is compared with the lowest average value in turn, and if the parameter value is greater than the lowest average value, the search cell is used to replace the existing cell corresponding to the lowest average value.
Specifically, when the number of cells in the cell list reaches the maximum, the cell list needs to be sorted according to the parameter values, the cells with large parameter values are reserved, and the cells with small parameter values are deleted, so as to ensure that the number of cells in the cell list does not exceed the maximum.
In the embodiment of the invention, the cell with higher parameter value can be updated in time in the cell list to keep the signal of the existing cell in the cell list stronger, so that when switching occurs, whether switching occurs can be determined based on the cell with better average value of the parameter values.
In the embodiment of the present invention, two cases, that is, the number of existing cells included in the cell list does not reach the preset upper limit and the number of existing cells included in the cell list reaches the preset upper limit, are configured respectively, and compared with the prior art, when the number of cells in the cell list does not reach the upper limit, the cells in the cell list are also deleted, which easily causes too few selectable cells and can not be switched in a serious case.
With continued reference to fig. 2, in a specific implementation of step S24, when a cell handover is required, it is determined whether to perform a handover according to a cell in the cell list where the average value of parameter values is largest.
In the embodiment of the invention, when switching occurs, whether switching is performed or not can be determined according to the cell with the largest average value of parameter values in the cell list, so that the switching effect is improved.
It is understood that in a specific application, besides the parameter value of the preset parameter (such as RSRP), the transceiving quality of some important signaling may be considered, for example, the quality of the signal to be measured satisfies the S criterion. Specifically, a cell with the highest transceiving quality of the signaling may be selected from one or more cells with larger parameter values of preset parameters (such as RSRP) and it may be determined whether handover is required; after a cell with the largest parameter value of the preset parameter (such as RSRP) is determined in the cell list, whether handover is required or not is determined according to the quality of the cell for receiving and transmitting the signaling.
It should be noted that the cell with the largest average value of the parameter values may be used to indicate that, within a preset time period in the past, the average value of the parameter values of each cell is determined, and then the cell with the largest average value is determined.
In the embodiment of the invention, the SMTC measuring window is adopted for searching, and because the measuring frequency of the SMTC measuring window is usually higher than the searching frequency of the searching window, compared with the prior art that the searching window is adopted for searching, the method can effectively increase the opportunity that the adjacent cells are searched, reduce the possibility that some cells with strong signals can not be searched all the time, and improve the switching effect.
Referring to fig. 6, fig. 6 is a schematic structural diagram of a cell switching apparatus according to an embodiment of the present invention. The cell switching apparatus may include:
a window determination module 61 adapted to determine an SMTC measurement window;
a parameter value determining module 62, adapted to search the SSBs of neighboring cells in the SMTC measurement window, and measure a preset parameter of each search cell where the SSBs are searched to obtain a parameter value of the search cell;

and the switching selection module 64 is adapted to determine whether to perform switching according to the cell with the largest average value of the parameter values in the cell list when cell switching is required.

Still further, the comparison sub-module may include: a sorting unit adapted to determine an average value of parameter values of each existing cell in the cell list and sort; and the comparison unit is suitable for comparing the parameter value of each search cell with the lowest average value in sequence, and when the parameter value is greater than the lowest average value, replacing the existing cell corresponding to the lowest average value with the search cell.
In the embodiment of the invention, the SMTC measuring window is adopted for searching, and because the measuring frequency of the SMTC measuring window is usually higher than the searching frequency of the searching window, compared with the prior art that the searching window is adopted for searching, the method can effectively increase the opportunity that the adjacent cells are searched, reduce the possibility that some cells with strong signals can not be searched all the time, and improve the switching effect.
