Detailed Description

Reference will now be made in detail to embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present application and should not be construed as limiting the present application.

A cell selection method, apparatus, terminal device, and storage medium according to embodiments of the present application are described below with reference to the accompanying drawings.

Fig. 1 is a flowchart illustrating a cell selection method according to an embodiment of the present application.

An execution subject of the cell selection method in the embodiment of the present application is a cell selection device, which may be disposed in a terminal device, where the terminal device may be a smart phone, a smart wearable device, a telephone watch, and the like, and is not limited in this embodiment.

As shown in fig. 1, the method may include the steps of:

step 101, determining a target cell where the terminal device resides.

In the embodiments of the present application, in each communication system, a signal coverage area of each network device, such as a base station, is generally divided into one or more cells, and each cell has a different cell identifier. After the terminal equipment searches the cell, the terminal equipment can reside in the searched cell. For convenience of description, a cell in which the terminal device currently resides is denoted as a target cell. The target cell may be a cell conforming to LTE (Long Term Evolution ) which is a 4G wireless communication technology, or a cell conforming to a Fifth Generation Mobile communication (5G) technology, and The embodiment Of The present invention is not limited in The Mobile communication system corresponding to The target cell.

Step 102, a target cell is inquired in the first cell list and the second cell list.

And the connection quality of each cell which is resided in the first cell list in history is higher than that of each cell which is resided in the second cell list in history. The connection quality indicates the signal quality of the cell, and the better the connection quality, the higher the signal quality of the cell is.

In the embodiment of the present application, two cell lists, namely a first cell list and a second cell list, are maintained in a terminal device, and the first cell list and the second cell list are generated in advance, as an implementation manner, a plurality of candidate cells with connection quality higher than a set connection quality are determined by counting connection quality of historical residential cells of the terminal device and according to the counted connection quality of each cell, and when the number of the candidate cells is greater than the set number of the cells that can be added in the first cell list, a set number of target cells with higher connection quality are selected from the candidate cells and added to the first cell list, and the remaining historical residential cells are added to the second cell list.

As a second implementation manner, the connection quality of the terminal device history resident cells is counted, the counted connection quality of each cell is sorted from high to low, the cells arranged in the front of the setting data are added to the first cell list, and the remaining history resident cells are added to the second cell list.

In an implementation manner of the embodiment of the present application, cells included in the first cell list and the second cell list may be periodically updated according to a set period, so as to improve accuracy of the first cell list and the second cell list, and provide a reference for whether to perform cell switching subsequently according to a measurement configuration requirement issued by a network device, thereby improving accuracy of cell selection.

In the embodiment of the present application, according to a target Cell in which a terminal device currently resides, queries are performed in a first Cell list and a second Cell list, as an implementation manner, the queries may be respectively matched with a PCI of each Cell in the first Cell list and a PCI of each Cell in the second Cell list according to a Physical Cell Identity (PCI) of the target Cell, and if the PCI of the target Cell is the same as the PCI of any Cell in the first Cell list, it is determined that the target Cell is in the first Cell list; if the PCI of the target cell is the same as the PCI of any cell in the second cell list, determining that the target cell is in the second cell list; and if the PCI of the target cell is different from the PCI of any cell in the first cell list, and the PCI of the target cell is also different from the PCI of any cell in the second cell list, determining that the target cell does not belong to the first cell list or the second cell list.

Step 103, in response to that the target cell exists in the second cell list and the terminal device is in a connected state, determining whether to perform cell handover according to the measurement configuration message acquired from the network device.

The terminal device establishes connection with the network device, and the connection may be direct connection or indirect connection, so that it is determined that the terminal device is in a connected state.

After residing in the target cell, the terminal device receives a measurement configuration message sent by the network device, where the network device may be a base station, and the network device notifies the measurement configuration message to the terminal device through a measConfig cell carried in an RRC Connection reconfiguration message, where the measurement configuration message includes indication information of a peripheral cell that the terminal device needs to measure, for example, frequency point information of the cell.

In the embodiment of the present application, when it is determined that a target cell exists in a second cell list and a terminal device is in a connected state, that is, the connection quality of the target cell where the terminal device currently resides is poor, and at the same time, when the terminal device performs a service such as data transmission, for example, a service such as web browsing and video watching, it is necessary to ensure that the terminal device can reside in a cell with good connection quality through cell switching, therefore, it is necessary to analyze a measurement configuration message acquired from a network device, determine that a frequency point to be measured indicated in the measurement configuration message belongs to a first cell list and/or a second cell list, and further determine whether cell search according to the frequency point to be measured is required and measure the signal quality of the searched cell, and if it is determined that the signal quality of the searched cell is required to be measured, a measurement report is generated and reported according to a measurement result, the network equipment determines a cell to be switched based on the reported measurement report so as to indicate the terminal equipment to switch the cell; if the signal quality of the searched cell is determined not to be required to be measured, no measurement report is generated and reported to the network equipment, so that cell switching is not required, but the terminal equipment continuously resides in the target cell, frequent cell switching is avoided, and compared with the prior art, the terminal equipment directly performs measurement reporting after acquiring the measurement configuration message sent by the network equipment, frequent cell switching is caused, even the terminal equipment is switched to a cell with poorer quality, the reliability of cell switching is improved, and the communication quality is improved.

And step 104, responding to the target cell existing in the first cell list, and continuing to camp on the target cell.

In the embodiment of the present application, when it is determined that the target cell does not exist in the second cell list but exists in the first cell list, since the cells included in the first cell list are all cells with better connection quality, the cell in which the terminal device currently resides does not need to be switched or reselected but continues to reside in the target cell, and it is ensured that the terminal device always resides in a cell with better signal quality, thereby improving communication quality.

In the cell selection method according to the embodiment of the present application, a camped target cell is determined, the target cell is queried in a first cell list and a second cell list, the connection quality of each cell camped historically in the first cell list is higher than that of each cell camped historically in the second cell list, in response to that the target cell exists in the second cell list and a terminal device is in a connected state, whether cell switching is performed is determined according to a measurement configuration message acquired from a network device, and in response to that the target cell exists in the first cell list, the target cell continues to be camped in the target cell. When the measurement configuration message is received, whether the terminal equipment continuously resides in the target cell or cell switching is determined by predetermining the first cell list with high connection quality and the second cell list with poor connection quality instead of directly performing cell measurement reporting according to the measurement configuration message obtained from the network equipment so as to perform cell switching, so that frequent cell switching of the terminal equipment is avoided, and the communication quality is improved. In the above embodiment, if the target cell exists in the second cell list and the terminal device is in the connected state, it is determined whether to perform cell handover based on the measurement configuration message acquired from the network device, and different scenarios are described below with the embodiment. Based on the foregoing embodiment, as a first scenario, fig. 2 is a schematic flowchart of another cell selection method provided in this embodiment, and as shown in fig. 2, the determining, in step 103, whether to perform cell handover according to a measurement configuration message acquired from a network device includes the following steps:

step 201, at least one frequency point to be measured carried in the measurement configuration message is acquired.

The measurement configuration message sent by the network device carries at least one frequency point to be measured, which needs to be measured by the terminal device, for example, the number of the frequency points to be measured is 1, or the number of the frequency points to be measured is 3, which are not listed here one by one.

Step 202, for each frequency point to be measured, matching the frequency point to be measured with the frequency point of the cell in the first cell list and the frequency point of the cell in the second cell list respectively.

In this embodiment, the first cell list includes a plurality of cells, and the frequency points of the plurality of cells may be the same or different, that is, the first cell list includes at least one frequency point. Similarly, the second cell list also includes at least one frequency point.

Aiming at each frequency point to be measured, the frequency point to be measured is respectively matched with a frequency point contained in a first cell list and a frequency point contained in a second cell list, the frequency point to be measured can be the same as at least one frequency point contained in the first cell list, or the frequency point to be measured can be the same as at least one frequency point contained in the second cell list, or the frequency point to be measured is the same as at least one frequency point contained in the first cell list and at least one frequency point contained in the second cell list, or the frequency point to be measured is different from at least one frequency point contained in the first cell list and at least one frequency point contained in the second cell list.

Step 203, in response to that the frequency points to be measured meet any one of the first setting conditions, performing cell search according to the frequency points to be measured.

In the embodiment of the present application, the first setting condition is: the frequency point to be measured is only the same as the frequency point of at least one cell included in the first cell list.

In the embodiment of the application, it is determined that the frequency point to be measured is only the same as the frequency point of at least one cell included in the first cell list, that is, the frequency point to be measured is only located in the first cell list, and then the cell under the frequency point to be measured is considered to be the cell with better signal quality, so that cell search is performed according to the frequency point to be measured.

Step 204, measuring the searched signal quality of the first cell to generate a first measurement report, and reporting the first measurement report to the network device.

The first measurement report is used for the network equipment to instruct the terminal equipment to perform cell switching. The network device determines the cell to which the terminal device is to be switched according to the acquired first measurement report, and sends the cell to the terminal device so as to indicate the terminal device to perform cell switching.

In this embodiment of the application, for convenience of differentiation, a searched cell is referred to as a first cell, and the signal quality of the first cell is measured according to measurement information carried in a measurement configuration message and used for measuring the signal quality of the searched cell, and a first measurement report is generated according to the measured signal quality of the first cell, where the signal quality may be signal strength, and the first measurement report is sent to a network device, so that the network device instructs a terminal device to switch to the first cell according to the first measurement report. Because the first cell belongs to the cell with better signal quality, the terminal equipment can reside in the cell with better signal quality, and the communication quality is improved.

And step 205, in response to that the frequency point to be measured is only the same as the frequency point of at least one cell included in the second cell list, not performing cell search according to the frequency point to be measured to continue residing in the target cell.

In the embodiment of the application, it is determined that the frequency point to be measured is only the same as the frequency point of at least one cell included in the second cell list, that is, the frequency point to be measured is only located in the second cell list, it is considered that the cell below the frequency point to be measured is a cell with poor signal quality, cell search is not performed according to the frequency point to be measured, signal quality of the searched cell is not measured, that is, a measurement report is not generated according to the signal quality of the searched cell, so that the network device cannot receive the measurement result of the reported cell, further, the terminal device is not instructed to perform cell handover according to the measurement report, and the terminal device continues to reside in the target cell, that is, the terminal device does not switch to the cell with poor signal quality, but continues to reside in the target cell, and unnecessary cell handover is avoided.

In the cell selection method in the embodiment of the application, based on the predetermined first cell list with high connection quality, the predetermined second cell list with poor connection quality, and the frequency point to be measured in the measurement configuration message, it is determined whether the terminal device continues to reside in the target cell or performs cell switching, instead of directly performing cell switching according to the measurement configuration message obtained from the network device, so that the terminal device is prevented from frequently performing cell switching, but remains in a cell with better connection quality, and communication quality is improved.

Based on the foregoing embodiment, as a second scenario, in the embodiment of the present application, a first setting condition is: the frequency point to be measured is different from the frequency points of the cells included in the second cell list, and the frequency points of the cells included in the first cell list are also different. Fig. 3 is a flowchart of another cell selection method according to an embodiment of the present application, and as shown in fig. 3, the determining whether to perform cell handover according to the measurement configuration message acquired from the network device in step 103 includes the following steps:

step 301, acquiring at least one frequency point to be measured carried in the measurement configuration message.

Step 302, for each frequency point to be measured, matching the frequency point to be measured with the frequency point of the cell in the first cell list and the frequency point of the cell in the second cell list respectively.

For step 301 and step 302, the explanation of the foregoing embodiment can be specifically referred to, the principle is the same, and details are not repeated in this embodiment.

Step 303, in response to that the frequency point to be measured is different from the frequency point of the cell included in the second cell list, and the frequency point to be measured is also different from the frequency point of the cell included in the first cell list, performing cell search according to the frequency point to be measured.

In the embodiment of the present application, under the condition that it is determined that the frequency point to be measured is different from the frequency point of the at least one cell included in the second cell list, and the frequency point to be measured is also different from the frequency point of the at least one cell included in the first cell list, it is indicated that the frequency point to be measured does not appear in the first cell list, and does not appear in the second cell list, and then cell search needs to be performed according to the frequency point to be measured.

The reason is that the target cell where the terminal device resides belongs to a cell in the second cell list with poor connection quality, and therefore, when the frequency point to be measured is determined to be different from the frequency point of at least one cell included in the second cell list and is not the same as the frequency point of at least one cell included in the first cell list, cell search is performed according to the frequency point to be measured, the signal quality of the searched first cell is measured to generate a first measurement report, and the first measurement report is sent to the network device, so that the terminal device can perform cell switching based on the cell to be switched determined by the network device according to the first measurement report, so as to switch to the cell with good signal quality, avoid staying in the target cell with poor connection quality all the time, and improve communication quality.

Step 304, measuring the searched signal quality of the first cell to generate a first measurement report, and reporting the first measurement report to the network device.

In step 304, reference may be made to the explanations in the foregoing embodiments, which are not repeated herein.

In the cell selection method according to the embodiment of the application, the target cell where the terminal device resides belongs to a cell in a second cell list with poor connection quality, and therefore, when the frequency point to be measured is determined to be different from the frequency point of at least one cell included in the second cell list and the frequency point of at least one cell included in the first cell list is also different, cell search is performed according to the frequency point to be measured, the signal quality of the searched first cell is measured to generate a first measurement report, and the first measurement report is sent to the network device, so that the terminal device can perform cell switching on the cell to be switched determined according to the first measurement report based on the network device, so as to switch to the cell with good signal quality, avoid staying in the target cell with poor connection quality all the time, and improve communication quality.

Based on the foregoing embodiment, as a third scenario, fig. 4 is a flowchart of another cell selection method provided in this embodiment, and is described in relation to a case that a frequency point to be measured is the same as at least one frequency point included in a first cell list, and at least one frequency point included in a second cell list is also the same, as shown in fig. 4, where determining whether to perform cell handover according to a measurement configuration message acquired from a network device in step 103 includes the following steps:

step 401, acquiring at least one frequency point to be measured carried in the measurement configuration message.

Step 402, for each frequency point to be measured, matching the frequency point to be measured with the frequency point of the cell in the first cell list and the frequency point of the cell in the second cell list respectively.

For step 401 and step 402, the explanation of the foregoing embodiment may be specifically referred to, and the principle is the same, which is not described again in this embodiment.

Step 403, in response to that the frequency point to be measured is the same as the frequency point of at least one cell included in the second cell list, and the frequency point to be measured is the same as the frequency point of at least one cell included in the first cell list, performing cell search according to the frequency point to be measured.

In the embodiment of the present application, when determining that the frequency point to be measured is the same as the frequency point of at least one cell included in the second cell list and the frequency point of at least one cell included in the first cell list, it indicates that the frequency point to be measured appears in both the first cell list and the second cell list. This is because a frequency point may include multiple cells, and therefore, a cell below the frequency point to be measured may be in the first cell list or the second cell list, so that the frequency point to be measured appears in both the first cell list and the second cell list, that is, based on matching of the frequency point to be measured, it cannot be determined whether the cell below the frequency point to be measured belongs to the first cell list or the second cell list, and then a cell search needs to be performed according to the frequency point to be measured to determine a cell corresponding to the frequency point to be measured, so as to obtain identification information of the cell to be measured, where the identification information of the cell is used to uniquely identify a corresponding cell, for example, PCI.

Step 404, matching the searched identification information of the second cell with the identification information of the cell included in the first cell list and the identification information of the cell included in the second cell list, respectively.

The identification information of the cell is the PCI of the cell, and can be used to uniquely identify a cell.

Step 405, in response to that the identification information of the second cell meets any second set condition, measuring the signal quality of the second cell to generate a second measurement report, and reporting the second measurement report to the network device.

the identification information of the second cell is different from the identification information of any cell contained in the first cell list, and the identification information of the second cell is also different from the identification information of any cell contained in the second cell list;

the identification information of the second cell is only the same as the identification information of any cell contained in the first cell list.

In one scenario, the identification information of the second cell is only the same as the identification information of any cell included in the first cell list, that is, the second cell is obtained by searching and belongs to the cell in the first cell list, that is, the searched second cell belongs to the cell with better connection quality, the signal quality of the second cell is measured to generate a second measurement report, and the second measurement report is sent to the network device. For the method of generating the second measurement report and sending the second measurement report to the network device, reference may be made to the explanation about the first measurement report in the foregoing embodiment, which is not described herein again.

In another scenario, if the identification information of the second cell is different from the identification information of any cell included in the first cell list, and the identification information of the second cell is also different from the identification information of any cell included in the second cell list, that is, if the second cell obtained by the search does not belong to the cell in the first cell list nor the cell in the second cell list, the signal quality of the second cell is measured, since the target cell where the terminal device resides belongs to the cell in the second cell list with poor connection quality, by generating the second measurement report and sending the second measurement report to the network device, the terminal device can perform cell handover to the cell with better signal quality based on the cell to be handed over determined by the network device according to the second measurement report, so as to avoid staying in the target cell with poor connection quality all the time, the communication quality is improved. For the method of generating the second measurement report and sending the second measurement report to the network device, reference may be made to the explanation in the foregoing embodiment, which is not described herein again.

And step 406, in response to that the identification information of the second cell is only the same as the identification information of any cell included in the second cell list, not measuring the signal quality of the second cell to continue camping on the target cell.

In the embodiment of the present application, it is determined that the identification information of the second cell is only the same as the identification information of any cell included in the second cell list, that is, the second cell obtained by searching belongs to a cell in the second cell list, that is, the searched second cell belongs to a cell with poor connection quality, the signal quality of the second cell is not measured, and a second measurement report is generated and reported to the network device, that is, the second cell continues to reside in the target cell, and then the cell to be switched continuously belongs to a cell with poor connection quality according to the feedback of the network device, and the communication quality is not improved when the cell is switched, but the connection quality is reduced due to the switching.

In the cell selection method of the embodiment of the application, in response to that a target cell exists in the second cell list and the terminal device is in a connected state, whether to measure and report the signal quality of the cell to be measured is determined according to the frequency point to be measured carried in the acquired measurement configuration message, so as to determine whether to perform cell switching, avoid unnecessary frequent switching of the cell, and enable the terminal device to reside in the cell with better connection quality as much as possible, so as to improve the communication quality.

Based on the foregoing embodiments, an embodiment of the present application provides another cell selection method, and fig. 5 is a schematic flowchart of the another cell selection method provided in the embodiment of the present application, as shown in fig. 5, the method includes the following steps:

step 501, determining a target cell where the terminal device resides.

Step 502, a target cell is searched in the first cell list and the second cell list.

Step 503, in response to that the target cell exists in the second cell list and the terminal device is in the connected state, determining whether to perform cell handover according to the measurement configuration message acquired from the network device.

The steps 501 to 503 can refer to the explanations in the foregoing embodiments, and the principle is the same, which is not described again in this embodiment.

Step 504, in response to that the target cell exists in the second cell list and the terminal device is in an idle state, performing cell search according to the frequency points of the cells included in the first cell list.

The terminal device is in an idle state, which means that all data connections of the terminal device are closed in an access stratum, that is, the terminal device does not perform services such as data transmission.

In the embodiment of the present application, it is determined that a target cell where the terminal device currently resides is in the second cell list, that is, the signal quality of the target cell or the connection quality is poor, and if the terminal device is in an idle state, that is, the terminal device does not currently execute a relevant service, cell search may be performed according to a frequency point of a cell included in the first cell list, so as to search for a corresponding cell.

And 505, in response to the searched cell, controlling the terminal device to reselect from the target cell to the searched cell.

And then, after the cell is searched, the terminal device is switched from the target cell which is resided at present to the cell which is searched at present, because the target cell belongs to the second cell list, the connection quality is poor, the cell search is carried out through the frequency point contained in the first cell list, and after the cell is searched, because the cell search is carried out according to the frequency point in the first cell list, the searched cell is the cell with higher connection quality, and then the cell reselection is carried out according to the searched cell to reselect to the searched cell, so that the situation that the terminal device is always resided in the target cell with poor connection quality and resided in the cell with higher connection quality through the cell reselection can be avoided, and the communication quality is improved.

If the first cell list is empty, the ue continues to camp on the current target cell.

Step 506, in response to the target cell existing in the first cell list, continuing to camp on the target cell.

In step 506, reference may be made to the explanations in the foregoing embodiments, and the principles are the same, which are not described herein again.

Step 507, in response to that neither the first cell list nor the second cell list contains the target cell, adding the target cell to the first cell list or the second cell list.

In the embodiment of the present application, a target cell is determined, that is, the target cell does not belong to a first cell list or a second cell list, and frequency points and/or identification information of the target cell need to be added to the first cell list or the second cell list according to the connection quality of the terminal in the target cell obtained through statistics, so as to update the first cell list and the second cell list.

In the cell selection method in the embodiment of the application, in response to that a target cell exists in the second cell list and the terminal device is in an idle state, cell search is performed according to the frequency points of the cells included in the first cell list, and the searched cells are reselected in response to the searched cells, so that when the terminal device is in the idle state, if the terminal device resides in a cell with poor connection quality, cell search is performed according to the frequency points in the first cell list with good connection quality, and the searched cells are reselected after the cell search is performed, so that the resident cells with poor connection quality are reselected to the cells with good connection quality, and the communication quality is improved.

Based on the foregoing embodiments, another cell selection method is provided in the embodiments of the present application, which specifies how to add a target cell to a corresponding first cell list or second cell list, and it should be noted that when determining a cell in the first cell list and a cell in the second cell list, the principle of the method for adding the target cell to the corresponding first cell list or second cell list is the same, and details are not repeated in this application. Fig. 6 is a flowchart of another cell selection method according to an embodiment of the present application, and as shown in fig. 6, step 507 includes the following steps:

step 601, in response to that neither the first cell list nor the second cell list includes the target cell, obtaining a connection parameter corresponding to the target cell.

In the embodiment of the application, under the condition that it is determined that the target cell does not belong to the first cell list or the second cell list, the connection parameter corresponding to the target cell is obtained, wherein the connection parameter corresponding to the target cell is obtained by statistics after the terminal device resides in the target cell. The connection parameter at least comprises one of the duration of the terminal device in the connection state and the number of times of executing the set action in the target cell.

Wherein, the connection state indicates that the terminal device is executing the service. The setting action includes one of: the switching on or off of the flight mode, the data switching on and off of the mobile communication, and the switching between different mobile communication systems, such as the switching between 4G and 5G, and the like. In general, when the signal quality of the camped cell is poor, the terminal device may frequently perform data on and off of mobile communication, or switch between 4G and 5G services, or achieve the purpose of improving the communication quality by turning on or off the flight mode, thereby setting the number of times of executing actions, and also indicating the signal quality of the camped cell.

Step 602, determining the connection quality corresponding to the target cell according to the connection parameter corresponding to the target cell.

In an implementation manner of the embodiment of the present application, a ratio between a duration of the terminal device being in the connection state and a number of times that the terminal device executes the set action in the target cell may be used as the connection quality corresponding to the target cell.

Step 603, adding the frequency point and/or the identification information of the target cell to the first cell list or the second cell list according to the connection quality corresponding to the target cell.

In an implementation manner of the embodiment of the present application, it is determined that the number of cells already included in a first cell list is equal to a set threshold, where the set threshold is a maximum value of the number of cells in the first cell list, that is, it is determined that the number of cells that can be added in the first cell list is full, then a minimum connection quality corresponding to each cell included in the first cell list is determined, and in a scenario, in response to that the connection quality corresponding to a target cell is greater than the minimum connection quality, a frequency point and/or identification information of the cell corresponding to the minimum connection quality is removed from the first cell list, and a frequency point and/or identification information of the target cell is added to the first cell list. In another scenario, in response to that the connection quality corresponding to the target cell is less than or equal to the lowest connection quality, the connection quality of the target cell is poor and cannot be added to the first cell list, so that the frequency point and/or the identification information added by the target cell is added to the second cell list.

For example, the set threshold of the cells that can be added in the first cell list is 5, and 5 cells have been added in the current first cell list, so that it is necessary to determine whether the target cell can be added to the first cell list according to the connection quality of the target cell. If 5 cells in the first cell list are respectively identified as 1, 2, 3, 4 and 5 according to the connection quality, the corresponding connection quality is respectively Q1, Q2, Q3, Q4 and Q5, the connection quality of the target cell is Qm, and if Qm is less than or equal to Q5, the frequency point and/or the identification information of the target cell are added into the second cell list; if Qm is larger than Q5, removing the frequency point and/or the identification information of Q5 from the first cell list, adding the frequency point and/or the identification information of the target cell into the first cell list, and adding the frequency point and/or the identification information of Q5 into the second cell list.

In another implementation manner of the embodiment of the present application, it is determined that the number of cells already included in the first cell list is smaller than a set threshold, that is, it is determined that the number of cells that can be added in the first cell list is not full, the highest connection quality corresponding to each cell included in the second cell list is determined, and in one scenario, in response to that the connection quality corresponding to a target cell is greater than the highest connection quality, a frequency point and/or identification information of the target cell is added to the first cell list. In another scenario, in response to that the connection quality corresponding to the target cell is less than the highest connection quality, removing the frequency point and/or the identification information of the cell corresponding to the highest connection quality from the second cell list, and adding the frequency point and/or the identification information of the target cell to the second cell list.

It should be understood that the number of cells in the second cell list is usually greater than the number of cells in the first cell list, and the number of cells in the second cell list may be set according to the needs of those skilled in the art, and if the number of cells added in the second cell list also reaches the corresponding threshold number, the cells removed from the first cell list are deleted, or one cell with higher connection quality than the cells removed from the first cell list is deleted and the cells removed from the first cell list are added to the second cell list according to the comparison between the connection quality of the cells removed from the first cell list and the connection quality of each cell in the second cell list.

In the cell selection method according to the embodiment of the present application, when it is determined that the target cell does not belong to the first cell list nor the second cell list, and when it is determined that the number of cells already included in the first cell list is equal to the set threshold, it is determined whether the target cell can be added to the first cell list according to the connection quality of the cells included in the first cell list and the connection quality of the target cell, so that accuracy of updating the first cell list is improved.

Further, in an implementation manner of the embodiment of the present application, in response to that the number of cells included in the first cell list is smaller than a set threshold, the frequency point and/or the identification information of the target cell is added to the first cell list.

For example, the set threshold of the cells that can be added to the first cell list is 5, and 4 cells have been added to the current first cell list, so that the frequency point and/or the identification information of the target cell can be directly added to the first cell list without comparing the connection quality of the target cell, and the adding efficiency is improved.
