[0049] Here, the exemplary embodiments will be described in detail, and the examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementation manners described in the following exemplary embodiments do not represent all implementation manners consistent with the present disclosure.

[0050] As described in the background art, terminals with foldable screens are being rapidly popularized. When a terminal with a foldable screen uses cellular communication in the folded state, due to the mutual interference of antennas, the receiving performance of the terminal with a foldable screen in the folded state becomes poor, resulting in a poor user experience.

[0051] In the related art, the ARD function is default enabled in the terminal device under cellular communication. This function dynamically switches to two receive antennas (2RX) or four receive antennas (4RX) according to the signal quality metric to improve the data transmission speed, enhance the network coverage, and improve the network connection stability. However, this function does not distinguish between the folded state and the unfolded state of the foldable device, nor does it consider the reception requirements of foreground applications, only considering the signal quality metric, such as call and game scenarios, and there is a situation where the switching causes a poor user experience.

[0052] To address the above problems, when the terminal uses cellular communication in the folded state or the unfolded state, the antenna switching of the terminal is controlled based on the current state of the terminal's foldable screen, so as to ensure the receiving performance of the terminal's foldable screen in different states and improve the user experience.

[0053] In an example of the first embodiment of the present disclosure, the terminal has a foldable screen and supports switching between a first antenna mode and a second antenna mode, wherein the number of antennas in the first antenna mode is greater than the number of antennas in the second antenna mode.

[0054] In an example of the first embodiment of the present disclosure, the first antenna mode of the terminal is to set the number of receiving antennas of the terminal to 4. The second antenna mode of the terminal is to set the number of receiving antennas of the terminal to 2.

[0055] Figure 1 It is a flowchart of an antenna switching control method shown according to an exemplary embodiment, as Figure 1 shown, the antenna switching control method includes the following steps.

[0056] In step S11, based on the current state of the foldable screen of the terminal, an antenna switching command is determined.

[0057] In the embodiment of the present disclosure, the current state of the foldable screen includes a folded state or an unfolded state.

[0058] The antenna switching command includes a first antenna switching command, a second antenna switching command, a third antenna switching command, and a fourth antenna switching command.

[0059] In the embodiment of the present disclosure, the first antenna switching command is used to control the current command executed by the ARD interface of the terminal to be to turn off the ARD function; the second antenna switching command is used to control the current command executed by the ARD interface of the terminal to be to turn on the ARD function; the third antenna switching command is to control the terminal to switch from the second antenna mode to the first antenna mode; the fourth antenna switching command is to control the terminal to switch from the first antenna mode to the second antenna mode.

[0060] In step S12, based on the antenna switching command, the terminal is controlled to switch between the first antenna mode and the second antenna mode.

[0061] The antenna switching control method provided by the embodiment of the present disclosure listens to the change in the folded state of the foldable screen of the terminal, and determines whether the current foldable screen of the terminal is in a folded state or an unfolded state. According to the state of the foldable screen of the terminal, a corresponding antenna switching command is determined to control the terminal to switch the antenna mode, overcoming the problem that the receiving performance of the terminal deteriorates due to inappropriate selection of the antenna mode.

[0062] The following embodiments of the present disclosure further explain and illustrate the antenna switching control method in the above embodiments of the present disclosure.

[0063] In an example of the present disclosure, the state of the foldable screen of the terminal is a folded state, and the determined antenna switching command is the first antenna switching command, and the first antenna switching command is used to control the terminal to switch to the first antenna mode.

[0064] In the embodiment of the present disclosure, when the folding screen is in the folded state, the control terminal is switched to the first antenna mode. In the first antenna mode, the number of antennas is relatively large, which can avoid the degradation of communication performance caused by the decrease in the number of antennas in the folded state and the mutual interference of the signals received by the antennas.

[0065] In the embodiment of the present disclosure, when the folding screen is in the folded state, the execution process of switching the control terminal to the first antenna mode can be implemented in the following manner:

[0066] In step S21, determine the current command executed by the ARD interface of the terminal.

[0067] Among them, the commands executed by the ARD interface include the command to enable the ARD function or the command to disable the ARD function. Among them, in the case of the command to enable the ARD function, the ARD function is enabled, that is, the antenna mode is switched based on the signal quality index and the signal quality index threshold. For example, the switching between 4RX and 2RX is performed. The command to disable the ARD function means that the antenna mode is not switched. For example, the first antenna switching mode is maintained, such as the 4RX antenna mode.

[0068] In step S22, in response to the current command executed by the ARD interface assigned to the terminal antenna reception being the command to enable the ARD function, disable the ARD function to make the terminal in the first antenna mode.

[0069] The ARD function command is used to control the terminal to switch between the first antenna mode and the second antenna mode based on the terminal signal quality index.

[0070] In step S23, in response to the current command executed by the ARD interface assigned to the terminal antenna reception being the command to disable the ARD function, keep the command to disable the ARD function and keep the terminal in the first antenna mode.

[0071] Among them, in the case of the command to disable the ARD function, the terminal is in the first antenna mode.

[0072] The following embodiments of the present disclosure further explain and illustrate the antenna switching control method in the above embodiments of the present disclosure.

[0073] In response to the folding screen of the terminal being in the folded state, determine the most recent antenna switching command executed by the terminal in the folded state. In the embodiment of the present disclosure, the most recent antenna switching command executed by the terminal in the folded state includes the first antenna switching command or the second antenna switching command. In response to the comparison result between the current antenna switching command and the most recent antenna switching command executed by the terminal in the folded state being different, determine to execute the current antenna switching command. In response to the comparison result between the current antenna switching command and the most recent antenna switching command executed by the terminal in the folded state being the same, determine to keep the most recent executed antenna switching command.

[0074] In the embodiments of the present disclosure, by comparing the current antenna switching command with the most recently executed antenna switching command when the terminal is in the folded state, if the comparison results are the same, the most recently executed antenna switching command is maintained. This can reduce the process of the terminal executing commands once, achieving the effect of saving the operating resources of the terminal.

[0075] In the embodiments of the present disclosure, in response to determining an antenna switching command when the terminal is in the folded state, it is determined that the terminal satisfies at least one of the following: the terminal satisfies the cellular communication state; the application currently running on the terminal is a preset whitelist application.

[0076] In the embodiments of the present disclosure, when the terminal is in the folded state, the first antenna switching command is determined, and the terminal is maintained in the first antenna mode, overcoming the deterioration of the signal reception performance caused by the mutual interference of the antennas when the terminal is in the folded state. The signal reception performance of the terminal in the folded state is ensured, improving the user experience.

[0077] Figure 3 It is a flowchart of determining an antenna switching command when the terminal is in the folded state shown according to an exemplary embodiment. As Figure 3 shown, the antenna switching control method when the terminal is in the folded state includes the following steps.

[0078] In step S31, in response to the folded screen state of the terminal being the folded state, the current network connection state of the terminal is determined.

[0079] In the embodiments of the present disclosure, the current network connection state of the terminal is divided into Wireless Fidelity (WIFI) communication and cellular communication.

[0080] In step S32, in response to the current network connection state of the terminal being cellular communication, the application currently running on the terminal is determined.

[0081] In the embodiments of the present disclosure, when the terminal in the folded state is in the case of inserting a card and camping on the network, the network connection state of the terminal is cellular communication. The user can normally browse the web, play games, and send and receive data. At this time, the terminal is in the service connection state.

[0082] In step S33, in response to the application currently running on the terminal being a preset whitelist application, the antenna switching command is determined to be the first antenna switching command.

[0083] In the embodiments of the present disclosure, the preset whitelist application is an application running when the folded screen of the terminal is in the folded state. The running application can be a preset application with a communication quality requirement greater than a threshold. In one example, the preset whitelist application can be a data application, for example.

[0084] In an example of the first embodiment of the present disclosure, the preset whitelist applications include calls and data type applications adapted to the external screen.

[0085] In the embodiment of the present disclosure, the first antenna switching command is used to control the current command executed by the ARD interface of the terminal to turn off the ARD function and keep the terminal in the first antenna mode at this time.

[0086] In step S34, in response to the application currently running on the terminal being a non-preset whitelist application, the antenna switching command is determined to be the second antenna switching command.

[0087] In the embodiment of the present disclosure, the second antenna switching command is used to control the current command executed by the ARD interface of the terminal to turn on the ARD function.

[0088] Among them, step S34 is an optional step.

[0089] Figure 4 It is a schematic flow chart of a terminal device with a folding screen executing the first antenna switching command in the folded state.

[0090] In the embodiment of the present disclosure, in response to the folding screen of the terminal device being in the folded state currently, the current network connection state of the terminal device is determined. In response to the terminal device being in the cellular communication network currently, it is determined that the application currently running on the terminal is a preset whitelist application. In response to the application currently running on the terminal being a preset whitelist application, it is determined that the current antenna switching command is the first antenna switching command. Compared with the most recently executed antenna switching command, if they are different commands, the current antenna switching command is executed to turn off the ARD function and make the terminal in the first antenna mode, which ensures the receiving performance of the terminal in the folded state and improves the user experience.

[0091] The following embodiments of the present disclosure further explain and illustrate the antenna switching control method for the unfolded state of the terminal folding screen.

[0092] In the embodiment of the present disclosure, different signal quality index thresholds are set for different service types of the terminal. Among them, different service types correspond to different signal quality index thresholds, and the signal quality index thresholds are used to control the terminal to execute the third antenna switching command or the fourth antenna switching command. The third antenna switching command is used to control the terminal to switch from the second antenna mode to the first antenna mode, and the fourth antenna switching command is used to control the terminal to switch from the first antenna mode to the second antenna mode.

[0093] In the embodiments of the present disclosure, the service types include voice communication services and data services. In the embodiments of the present disclosure, the signal metric thresholds matching the voice communication services include: Signal to Noise Ratio (SNR) metric, Reference Signal Receiving Power (RSRP) metric, and Downlink Scheduling Resource metric DL Grant.

[0094] In the embodiments of the present disclosure, the signal metric thresholds matching the data services include:

[0095] Signal to Noise Ratio (SNR) metric, Reference Signal Receiving Power (RSRP) metric, and Downlink Scheduling Resource metric DL Grant.

[0096] In the embodiments of the present disclosure, the SNR metric threshold / RSRP metric threshold corresponding to the voice communication services is the same as the SNR metric threshold / RSRP metric threshold corresponding to the data services; the DL Grant threshold corresponding to the voice communication services is less than the DL Grant threshold corresponding to the data services.

[0097] In the embodiments of the present disclosure, when the folding screen state of the terminal is in the unfolded state, determine the current service type of the application currently running on the terminal. Invoke the current signal metric threshold matching the current service type; based on the current signal metric threshold and the current signal metrics of the terminal, determine that the antenna switching command is the third antenna switching command or the fourth antenna switching command.

[0098] Among them, in an exemplary embodiment of the present disclosure, the terminal may also, when determining to perform cellular communication, perform the above-mentioned antenna switching control based on the signal metric thresholds of different service types.

[0099] Figure 5 It is a flowchart of the terminal determining the antenna switching command in the unfolded state shown according to an exemplary embodiment, as Figure 5 shown, the terminal determining the antenna switching command in the unfolded state includes the following steps.

[0100] In step S51, in response to the folding screen state of the terminal being in the unfolded state, determine the current network connection state of the terminal.

[0101] In step S52, in response to the current network connection state of the terminal being cellular communication, determine the service type corresponding to the application currently running on the terminal.

[0102] In the embodiments of the present disclosure, the service types include voice communication services and data services. Among them, the data services include audio-visual services and game services.

[0103] In step S53, based on the current signal metric threshold and the current signal metric of the terminal, determine that the antenna switching command is the third antenna switching command or the fourth antenna switching command.

[0104] In an embodiment of the present disclosure, in response to the antenna switching command of the ARD function being to control the terminal to switch from the second antenna mode to the first antenna mode, determine that the current antenna switching command of the terminal in the unfolded state is the third antenna switching command. In response to the antenna switching command of the ARD function being to control the terminal to switch from the first antenna mode to the second antenna mode, determine that the current antenna switching command of the terminal in the unfolded state is the fourth antenna switching command.

[0105] In an embodiment of the present disclosure, when the terminal is in the unfolded state, according to the execution result of the ARD function, determine whether the current antenna switching command of the terminal in the unfolded state is the third antenna switching command or the fourth antenna switching command. Through the ARD function, the antenna switching command can be initially judged. Based on the antenna switching command, different threshold conditions are called to determine whether the current antenna switching command is executed. The terminal in the unfolded state can determine the corresponding antenna switching command according to different scenarios, ensuring the reception performance of the terminal in the unfolded state and improving the user experience.

[0106] In one example, in response to the antenna switching command being the third antenna switching command, if the current signal metric meets the first condition, determine the currently executed antenna switching command. If the current antenna switching command is the same as the most recently executed antenna switching command, keep using the most recently executed antenna switching command. If the current antenna switching command is different from the most recently executed antenna switching command, execute the current antenna switching command.

[0107] Figure 6 is a flowchart of a terminal determining an antenna switching command in an unfolded state shown according to an exemplary embodiment, as Figure 6 shown, the steps for a terminal to determine an antenna switching command in an unfolded state include the following.

[0108] In step S61, call the signal metric threshold that matches the current service type.

[0109] In step S62, in response to the current signal quality metric of the terminal meeting the called signal metric threshold, determine that the current antenna switching command of the terminal in the unfolded state is the fourth antenna switching command.

[0114] In step S71, in response to the current antenna switching command of the terminal in the unfolded state being the third antenna switching command, a first condition of the signal index is determined.

[0115] In the embodiments of the present disclosure, the first condition of the signal index includes: SNR and RSRP satisfy the corresponding signal index thresholds. In one example, the first condition is SNR ≤ 6 dBm || RSRP ≤ -105 dBm.

[0116] In step S72, in response to the current signal quality index of the terminal satisfying the first condition of the signal index, it is determined that the current antenna switching command of the terminal in the unfolded state is the third antenna switching command.

[0117] In step S73, in response to the current signal quality index of the terminal not satisfying the first condition of the signal index, the most recently executed antenna switching command is maintained.

[0124] In step S83, in response to the comparison result between the current antenna switching command and the most recent antenna switching command executed by the terminal in the folded state being the same, determine to maintain the most recent antenna switching command.

[0125] In an embodiment of the present disclosure, by comparing the current antenna switching command of the terminal in the unfolded state with the most recent antenna switching command executed, if the comparison result is the same, then maintain the use of the most recent antenna switching command. This can reduce the process of the terminal executing a command once and achieve the effect of saving the operating resources of the terminal.

[0126] Figure 9 It is a flowchart of a terminal device with a folding screen executing a third antenna switching command and a fourth antenna switching command in the unfolded state.

[0127] In an embodiment of the present disclosure, in response to the folding screen of the terminal device being currently in the unfolded state, determine the current network connection state of the terminal device. In response to the terminal device being currently in a cellular communication network, monitor the signal change of the terminal device. Based on the execution result of the ARD function, determine whether the current antenna switching command of the terminal device is a third antenna switching command or a fourth antenna switching command. In response to the current antenna switching command of the terminal device being a third antenna switching command, call the first condition of the signal index. If the current signal index of the terminal device meets the first condition of the signal index, then compare the current antenna switching command of the terminal device in the unfolded state with the most recent antenna switching command executed. In response to the comparison result being different, execute the third antenna switching command. In response to the current antenna switching command of the terminal device being a fourth antenna switching command, based on the service type of the application currently running on the terminal device, call the signal index threshold corresponding to the service type. If the current signal index of the terminal device meets the signal index threshold, then compare the current antenna switching command of the terminal device in the unfolded state with the most recent antenna switching command executed. In response to the comparison result being different, execute the fourth antenna switching command.

[0128] In one example, when the signal-to-noise ratio (SNR) in the terminal signal quality indicator is greater than the first SNR indicator threshold, the downlink scheduling resource indicator (DL Grant) is less than the first downlink scheduling resource indicator threshold, and there is no 3 / 4 stream downlink scheduling, the terminal is controlled to switch to the second antenna mode.

[0129] When the SNR in the terminal signal quality indicator is less than the first SNR indicator threshold, or the DL Grant is greater than the first downlink scheduling resource indicator threshold, or there is 3 / 4 stream downlink scheduling, the terminal is controlled to switch to the first antenna mode.

[0130] In one example of an embodiment of the present disclosure, the first SNR indicator threshold may be -6 dBm, and the first downlink scheduling resource indicator threshold may be 10%.

[0131] In one example of an embodiment of the present disclosure, the first condition of the signal indicator may be: the SNR ≤ 6 dBm or the reference signal received power indicator ≤ -105 dBm.

[0132] In the embodiments of the present disclosure, the signal indicator threshold includes a first signal indicator threshold and a second signal indicator threshold.

[0133] In one example of an embodiment of the present disclosure, the first signal indicator threshold may be: the SNR ≥ 9 dBm && the reference signal received power indicator RSRP ≥ -95 dBm && the downlink scheduling resource indicator ≤ 0%.

[0134] In one example of an embodiment of the present disclosure, the second signal indicator threshold may be: the SNR ≥ 9 dBm && the reference signal received power indicator RSRP ≥ -95 dBm && the downlink scheduling resource indicator ≤ 10%.

[0135] In the embodiments of the present disclosure, based on the comparison result of the current signal indicator of the terminal in the unfolded state with different thresholds, the third antenna switching command or the fourth antenna switching command is executed, and an appropriate terminal antenna mode can be selected, which can simultaneously meet the needs of the terminal for different service types, ensure the antenna reception performance, and improve the user experience.

[0136] In one example embodiment of the present disclosure, the signal indicator threshold includes a signal-to-noise ratio indicator threshold and a reference signal received power indicator threshold, and the signal-to-noise ratio indicator threshold and the reference signal received power indicator threshold can be dynamically adjusted.

[0137] In one example, the embodiments of the present disclosure can adjust the signal-to-noise ratio indicator threshold and the reference signal received power indicator threshold based on the block error rate.

[0138] In one example, the monitoring target metric threshold is the block error rate within the preset metric threshold range, and the average block error rate of the block error rate within the specified window is determined. Based on the average block error rate and the average block error rate threshold, the quantity of the first type and the quantity of the second type are determined. The quantity of the first type represents the number of times the metric threshold meets the condition, and the quantity of the second type represents the number of times the metric threshold does not meet the condition. Based on the ratio of the quantity of the first type to the quantity of the second type and the number of times the terminal executes the target antenna switching command, the target metric threshold is adjusted.

[0139] The following embodiments of the present disclosure further explain and illustrate the antenna switching control method in the above embodiments of the present disclosure.

[0140] Figure 10 is a flowchart of a calculation method for performing a moving average on the block error rate when the terminal is in the unfolded state according to an exemplary embodiment, as Figure 10 shown, the calculation method for performing a moving average on the block error rate when the terminal is in the unfolded state includes the following steps.

[0141] In step S101, in response to the current antenna switching command of the terminal, the initial value of the target metric threshold is determined.

[0142] In the embodiments of the present disclosure, the target metric threshold is the value of the reference signal received power metric RSRP in the signal metric threshold, where the target metric threshold includes a first target threshold and a second target threshold.

[0143] In step S102, in response to determining the initial value of the target metric threshold, the block error rate near the initial value of the target metric threshold is recorded.

[0144] In the embodiments of the present disclosure, the block error rate includes a first block error rate and a second block error rate.

[0145] In the embodiments of the present disclosure, the block error rate near the first target metric threshold is recorded as the first block error rate; the block error rate near the second target metric threshold is recorded as the second block error rate.

[0146] In step S103, a moving average calculation is performed on the downlink block error rate.

[0147] In the embodiments of the present disclosure, a moving average calculation is performed on the downlink first block error rate and the downlink second block error rate to obtain a first average block error rate and a second average block error rate respectively, and the calculation result of each time is recorded.

[0148] In step S104, in response to the terminal executing the antenna switching command, the quality of the block error rate before switching is determined.

[0149] In response to the average block error rate of the first quantity before the terminal determines to execute the antenna switching command being less than the first average block error rate threshold, accumulate the first type of quantity; in response to the average block error rate of the first quantity before the terminal determines to execute the antenna switching command being greater than or equal to the second average block error rate threshold, accumulate the second type of quantity; the second average block error rate is greater than the first average block error rate.

[0150] In the embodiments of the present disclosure, if the 3 - time downlink average block error rate before executing the antenna switching command is less than the first average block error rate threshold, the count of num_avg_better is incremented by 1; if the 3 - time downlink average block error rate before executing the antenna switching command is greater than or equal to the second average block error rate threshold, the count of num_avg_bad is incremented by 1.

[0151] In the embodiments of the present disclosure, num_avg_better represents the quantity of which the index threshold meets the condition, and num_avg_bad represents the quantity of which the index threshold does not meet the condition.

[0152] In the embodiments of the present disclosure, num_avg_better can be expressed as the first type of quantity; num_avg_bad can be expressed as the second type of quantity.

[0153] Based on the ratio of the first type of quantity to the second type of quantity, and the number of times the terminal executes the target antenna switching command, adjust the target index threshold, including: if the number of times the terminal executes the target antenna switching command is greater than the number threshold and the ratio is greater than 1, then lower the target index threshold; or if the number of times the terminal executes the target antenna switching command is greater than the number threshold and the ratio is less than or equal to 1, then increase the target index threshold.

[0154] Figure 11 is a flowchart of a method for adjusting the target index threshold of a terminal in the unfolded state shown according to an exemplary embodiment, as Figure 11 shown, the method for adjusting the target index threshold of a terminal in the unfolded state includes the following steps.

[0155] In step S111, record the number num_ard of times the third antenna switching command is executed throughout the day.

[0156] In step S112, calculate the ratio result of num_avg_better to num_avg_bad.

[0157] In step S113, in response to the calculation result of result, adjust the target index threshold.

[0158] In an embodiment of the present disclosure, if the number of times num_ard of executing the third antenna switching command throughout the day is greater than 20 and result > 1, then subtract 1 from the target metric threshold; if the number of times num_ard of executing the third antenna switching command throughout the day is greater than 20 and result ≤ 1, then add 1 to the target metric threshold.

[0159] In an embodiment of the present disclosure, the adjustment range of the target metric threshold is ±5 dBm of the initial value.

[0160] In an embodiment of the present disclosure, the determined target metric threshold adjusted on the current day can be recorded. If the target threshold is determined to be adjusted continuously for N times, then adjust the target threshold at a set time to make it effective. N is a positive integer.

[0161] In an embodiment of the present disclosure, record the target metric threshold adjusted on the current day. If the target metric thresholds recorded for two consecutive days are the same value, make the recorded target metric threshold effective; if the target metric thresholds recorded for two consecutive days are not the same value, then clear the target metric threshold recorded on the first day.

[0162] In an embodiment of the present disclosure, write the target metric threshold to be made effective at 12 o'clock on the second night into the EFS file: ard_config, and restart the subsystem to load the new target metric threshold.

[0163] In an embodiment of the present disclosure, considering that the environments of different terminals are not consistent, adjusting the target metric threshold can achieve better reception performance and improve the user experience.

[0170] In an example of Embodiment 1 of the present disclosure, if the 3 times of the second average block error rate in the downlink before executing the antenna switching command are all less than the first average block error rate threshold, the count of num_avg_better_2 is incremented by 1; if the 3 times of the second average block error rate in the downlink before executing the antenna switching command are all greater than or equal to the second average block error rate threshold, the count of num_avg_bad_2 is incremented by 1.

[0171] In an example of Embodiment 1 of the present disclosure, if the 3 times of the second average block error rate in the downlink before executing the antenna switching command are all less than the first average block error rate threshold, the count of num_avg_better_2 is incremented by 1; if the 3 times of the second average block error rate in the downlink before executing the antenna switching command are all greater than or equal to the second average block error rate threshold, the count of num_avg_bad_2 is incremented by 1.

[0172] In an example of Embodiment 1 of the present disclosure, the first average block error rate threshold may be 10%, and the second average block error rate may be 20%.

[0173] In the present embodiment, record the number of times num_ard of executing the third antenna switching command throughout the day, calculate the ratio result of num_avg_better and num_avg_bad, and adjust the target index threshold in response to the calculation result of result.

[0175] In the present embodiment, calculate the ratio of num_avg_better_1 and num_avg_bad_1, denoted as result_1; calculate the ratio of num_avg_better_2 and num_avg_bad_2, denoted as result_2.

[0176] In the first example of the embodiments of the present disclosure, if the number of times num_ard of executing the third antenna switching command throughout the day is greater than 20 and result_1 > 1, then subtract 1 from the first target metric threshold; if the number of times num_ard of executing the third antenna switching command throughout the day is greater than 20 and result_1 ≤ 1, then add 1 to the first target metric threshold.

[0177] In the first example of the embodiments of the present disclosure, if the number of times num_ard of executing the third antenna switching command throughout the day is greater than 20 and result_2 > 1, then subtract 1 from the second target metric threshold; if the number of times num_ard of executing the third antenna switching command throughout the day is greater than 20 and result_2 ≤ 1, then add 1 to the second target metric threshold.

[0178] In the embodiments of the present disclosure, record the target metric threshold adjusted on the current day. If the target metric thresholds recorded for two consecutive days are the same value, write the target metric threshold that will take effect at 12 o'clock on the second night into the EFS file: ard_config, and restart the subsystem to load the new target metric threshold.
