Description

Technical Field

[0001] The present invention relates to the field of communication technology, and in particular to a network performance optimization method, a network performance optimization device, and a storage medium. Background Art

[0002] To reduce inter-cell interference and improve overall network performance, existing technologies mostly use uplink closed-loop power control to accurately adjust the uplink transmit power of terminals within a cell. That is, the base station generates power control commands based on power control parameters and measurement results of terminals within the cell. The terminal then adjusts its transmit power up, down, or maintains it according to the received power control commands. This power control method requires that the terminal's transmit power be in a normal and controllable state. However, abnormal terminals with out-of-control transmit power often appear in the network. In other words, terminals whose transmit power cannot be adjusted by the base station's normal power control. The presence of these abnormal terminals can increase the network's noise floor, drowning out useful signals, affecting network performance, and degrading the user experience within the network.

[0003] Therefore, how to optimize network performance and improve user experience has become an urgent problem to be solved. Summary of the Invention

[0004] The main purpose of the embodiments of the present invention is to provide a network performance optimization method, a network performance optimization device and a storage medium, aiming to optimize network performance and improve user experience.

[0005] In a first aspect, an embodiment of the present invention provides a network performance optimization method, comprising:

[0006] Based on the performance indicators of the cell, it is determined whether there is a potential abnormal terminal in the cell; if there is a potential abnormal terminal in the cell, power control screening is performed on the terminals in the cell to determine a target abnormal terminal; the target abnormal terminal is released and notified to re-access the network of the cell.

[0007] In a second aspect, an embodiment of the present invention further provides a network performance optimization device, which includes a processor, a memory, a computer program stored on the memory and executable by the processor, and a data bus for realizing connection and communication between the processor and the memory, wherein when the computer program is executed by the processor, the steps of any one of the network performance optimization methods provided in the specification of the present invention are implemented.

[0009] An embodiment of the present invention provides a network performance optimization method, a network performance optimization device, and a storage medium. The embodiment of the present invention determines whether there are potential abnormal terminals in the cell based on the performance indicators of the cell. When there are potential abnormal terminals in the cell, power control screening is performed on the terminals in the cell to determine the target abnormal terminal. Finally, the target abnormal terminal is released and then reconnected to the cell network, completing the processing and reconnection of the target abnormal terminal. Through two screenings based on performance indicators and power control, the target abnormal terminal that affects the network in the cell is determined, and then the target abnormal terminal is released from the network. After the release, the target abnormal terminal is reconnected to the network, reducing the impact on the network in the cell and ensuring the network experience of other users in the network. At the same time, reconnecting the target abnormal terminal to the network also ensures the network experience of users using the target abnormal terminal. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0016] The flowcharts shown in the accompanying drawings are for illustrative purposes only and do not necessarily include all contents and operations / steps, nor must they be executed in the order described. For example, some operations / steps may be decomposed, combined, or partially merged, so the actual execution order may vary depending on the actual situation.

[0017] It should be understood that the terms used in this specification are only for the purpose of describing particular embodiments and are not intended to limit the present invention. As used in the specification and appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms unless the context clearly indicates otherwise.

[0018] Cellular mobile communication systems consist of base stations and terminals. A single base station serves multiple terminals simultaneously within its coverage area. Uplink closed-loop power control is typically optimized to more accurately adjust the terminal's uplink transmit power, reducing inter-cell interference and improving overall network performance. However, in high-capacity outdoor scenarios, terminals with out-of-control transmit power often occur. These terminals, in other words, abnormal transmit power levels that cannot be adjusted by the base station's normal power control process, raise the noise floor of the entire network, ultimately drowning out useful signals and severely impacting overall network performance and the user experience.

[0019] Therefore, the embodiments of the present invention provide a network performance optimization method, a network performance optimization device and a storage medium, which screen out target abnormal terminals from the network and process the screened target abnormal terminals to achieve the purpose of improving network performance and optimizing network performance.

[0020] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features therein may be combined with each other.

[0021] Please refer to Figure 1 , Figure 1 A flowchart of a network performance optimization method provided by an embodiment of the present invention.

[0022] like Figure 1 As shown, the network performance optimization method includes steps S101 to S103.

[0023] Step S101: Determine whether there is a potential abnormal terminal in the cell based on the performance indicators of the cell.

[0024] When a potential abnormal terminal exists in a cell, its terminal performance indicators may be abnormal, further affecting the cell performance indicators. Therefore, the cell performance indicators can be used to make a preliminary judgment on whether there is a potential abnormal terminal in the cell. A potential abnormal terminal refers to a terminal with potential power outage.

[0025] In one embodiment, the performance indicators include cell performance indicators and terminal performance indicators; based on the cell performance indicators, determining whether there are potential abnormal terminals in the cell includes: determining whether the cell performance indicators meet preset indicator conditions; if the cell performance indicators do not meet the preset indicator conditions, determining whether the terminal performance indicators of the terminals in the cell are normal; if the terminal performance indicators of the terminals in the cell are abnormal, determining that there are potential abnormal terminals in the cell.

[0026] Cell performance indicators refer to the overall performance indicators of the cell, such as the cell's received signal strength, interference noise, and throughput. Among them, the cell's received signal strength refers to the received power of the entire bandwidth. Here, no distinction is made between control channels and service channels. It refers to the sum of the power of the useful signal and noise. Interference noise refers to the noise generated by the entire bandwidth when the service is loaded. Specifically, it refers to the average interference noise of each RB in the entire bandwidth. RB is the resource unit for the allocation of service channel resources. In addition to relying on the above-mentioned power indicators, the calculation of throughput is also related to the bandwidth, number of users, and frame structure, which are not limited here.

[0027] Terminal performance indicators refer to the terminal performance indicators of each terminal in the cell, such as the terminal's useful signal strength. The terminal's useful signal strength is related to the received signal strength, as well as the number of antennas, bandwidth, and other factors. These factors are not limited here, and the terminal's useful signal strength can be calculated based on the above information.

[0028] Determine whether the cell performance indicators meet the preset indicator conditions. If the cell performance indicators do not meet the preset indicator conditions, it can be considered that there may be potential abnormal terminals in the cell. The terminal performance indicators of the terminals in the cell can be judged. When the terminal performance indicators of the terminals in the cell are abnormal, it can be determined that there are potential abnormal terminals in the cell.

[0029] For example, if the received signal strength and interference noise are higher than normal values, and the throughput is lower than normal values, it can be considered that there may be at least one potential abnormal terminal in the cell.

[0030] In one embodiment, the terminal performance indicator includes a useful received signal strength; determining whether the terminal performance indicator of the terminal in the cell is normal includes: judging whether the useful received signal strength of the terminal in the cell is within a preset range; if the useful received signal strength of the terminal in the cell is not within the preset range, determining that the terminal performance indicator of the terminal in the cell is abnormal.

[0031] Changes in the terminal performance indicators of terminals within a cell can affect the cell performance indicators of the cell. Therefore, the terminal performance indicators of terminals within the cell can be converted based on the cell performance indicators that meet the preset indicator conditions to ensure normal cell performance indicators. The numerical range corresponding to the converted terminal performance indicators of terminals within the cell is used as the preset range.

[0032] Because terminal performance indicators include useful received signal strength, when the useful received signal strength of a terminal in a cell is within a preset range, the terminal's terminal performance indicator is considered normal and the terminal is controllable. If the useful received signal strength of a terminal in a cell is not within the preset range, the terminal's terminal performance indicator is considered abnormal.

[0033] In specific implementations, to reduce misjudgments of potentially abnormal terminals, the terminal performance indicator of a terminal may be determined to be abnormal only when the useful received signal strength of the terminal in the cell is outside the preset range for multiple consecutive times. Multiple consecutive times means two or more times.

[0034] It should be noted that when the useful received signal strength of the terminal in the cell is not within the preset range twice, there may be three situations, namely: the useful received signal strength of the terminal in the cell is greater than the maximum value of the preset range twice, the useful received signal strength of the terminal in the cell is less than the minimum value of the preset range twice, and the useful received signal strength of the terminal in the cell is greater than the maximum value of the preset range once and less than the minimum value of the preset range once.

[0035] In order to reduce the misjudgment of potential abnormal terminals, at this time, the terminal performance indicator of the terminal is considered abnormal only in the following two cases: the useful received signal strength of the terminal in the cell is greater than the maximum value of the preset range twice, and the useful received signal strength of the terminal in the cell is less than the minimum value of the preset range twice.

[0036] S102: If there are potential abnormal terminals in the cell, perform power control screening on the terminals in the cell to determine target abnormal terminals.

[0037] After identifying potential abnormal terminals within a cell, the base station performs power control screening on the terminals within the cell to identify the target abnormal terminals. Power control screening involves the base station sending power control commands to terminals within the cell, thereby controlling the terminals' transmit power adjustments. Screening is performed based on the terminals' transmit power adjustments.

[0038] In one embodiment, before performing power control screening on terminals in a cell, the method includes: determining terminals to be controlled from terminals in the cell based on power information of the terminals in the cell; and performing power control screening on terminals in the cell, including: performing power control screening on the terminals to be controlled.

[0039] After identifying a potential abnormal terminal within a cell, the base station obtains power information from each terminal within the cell, including received signal strength and / or signal-to-noise ratio. Based on this information, the base station identifies terminals to be controlled. These terminals require the base station to send power control commands for transmit power control.

[0040] For example, terminals with a signal-to-noise ratio greater than a target signal-to-noise ratio threshold may be used as terminals to be controlled. The base station needs to reduce the power of such high-power terminals, that is, send a power reduction command to such terminals.

[0041] For another example, terminals with received signal strength greater than or equal to a preset threshold may be used as terminals to be controlled. The base station needs to reduce the power of such high-power terminals, that is, send a power reduction command to such terminals.

[0042] For another example, a terminal with a signal-to-noise ratio less than the target signal-to-noise ratio threshold and a received signal strength less than or equal to a preset threshold can also be considered a terminal to be controlled. The base station needs to increase the power of such low-power terminals, that is, send a power increase command to such terminals. However, it should be noted that when sending a power increase command to such terminals, the maximum transmit power of the terminal needs to be considered. That is, when the base station sends a power increase command, the maximum power increase cannot exceed the maximum transmit power of the terminal.

[0043] After determining the terminal to be controlled, the base station will send a power adjustment command to the terminal to be controlled, and perform power control screening on the terminal according to the response of the terminal to be controlled based on the power adjustment command.

[0044] In one embodiment, power control screening is performed on terminals in a cell to determine target abnormal terminals, including: determining a transmit power difference after two consecutive transmit power adjustments of the terminals in the cell; and determining the target abnormal terminal from the terminals in the cell based on the transmit power difference.

[0045] After the base station sends a power adjustment command to terminals within a cell, the terminals adjust their transmit power based on the power adjustment command. The base station records the transmit power values ​​of the terminals within the cell after two consecutive transmit power adjustments. The base station calculates the difference between the two transmit power adjustments and uses this difference as the transmit power difference between the two consecutive transmit power adjustments. This transmit power difference is then used to identify abnormal terminals from the terminals within the cell.

[0046] In one embodiment, before determining the transmit power difference after two adjacent transmit power adjustments are performed on a terminal in a cell, the method includes: performing transmit power control on the terminal in the cell based on the power information of the terminal in the cell, and determining the control type and number of controls of the transmit power control; determining the transmit power difference after two adjacent transmit power adjustments are performed on the terminal in the cell, including: if the control type of the transmit power control is the same and the number of controls is greater than a preset number, determining the transmit power difference after two adjacent power adjustments are performed on the terminal in the cell.

[0047] The power information includes received signal strength and / or signal-to-noise ratio. The base station performs transmit power control for terminals within the cell based on the power information of each terminal. After the base station sends a transmit power control command to a terminal to be controlled, the base station calculates the control type and number of transmit power control commands sent to the terminal to be controlled. Control types include power increase and power decrease, and the number of control times is the number of times the transmit power control command is sent to the terminal to be controlled.

[0048] If the control type of the transmission power control command sent by the base station to the terminal to be controlled is the same and the number of controls is greater than the preset number, it can be considered that the terminal to be controlled may not be controlled by the transmission power control command sent by the base station. Then, by determining the difference in transmission power after two adjacent power adjustments of the terminal to be controlled, it is determined whether the terminal to be controlled is the target abnormal terminal.

[0049] Since the target abnormal terminal is a terminal whose transmission power is out of control, in one embodiment, the target abnormal terminal is determined from the terminals in the cell according to the transmission power difference, including: if the absolute value of the transmission power difference is less than a preset value, the terminal in the cell is determined as the target abnormal terminal.

[0050] The transmit power difference is the difference between the transmit power values ​​of the terminal in the cell after two adjacent transmit power adjustments. Therefore, if the absolute value of the transmit power difference of the terminal is less than the preset value, it can be considered that the terminal has no response to the transmit power command of the base station, and the terminal can be identified as a target abnormal terminal.

[0051] During implementation, to reduce errors caused by small-scale transmit power adjustments and terminal radio frequency issues, a terminal can be identified as a target abnormal terminal if the absolute value of the transmit power difference of the terminal is less than a preset value multiple times in a row. In practice, the theoretical value of the preset value is 0, meaning that the transmit power value of a terminal within a cell remains unchanged after two consecutive transmit power adjustments. However, due to fluctuations in transmit power of terminals within a cell and errors caused by terminal radio frequency issues during actual use, the preset value can be set to a value greater than 0. The specific value can be determined based on experience.

[0052] S103: Release the target abnormal terminal and notify the target abnormal terminal to re-access the cell's network.

[0053] After the target abnormal terminal is released and re-accesses the network, the power abnormality of the target abnormal terminal will be greatly weakened. In most cases, it will not affect the overall cell performance indicators of the cell, and will not have much impact on the experience of other terminal users in the network. That is, the impact on other terminals in the network will be effectively alleviated. Therefore, after determining the target abnormal terminal, the target abnormal terminal can be released, and after the release, the released target abnormal terminal can be notified to re-access the cell network.

[0054] For NSA terminals (non-independent networking terminals), the base station can directly notify the terminal to deactivate 5G, and the base station re-issues the measurement configuration. After meeting the measurement threshold, the terminal reports the measurement report and rejoins the 5G network.

[0055] For SA terminals (standalone networking terminals), the terminals can rejoin the 5G network by re-establishing.

[0056] It should be noted that for NSA terminals and SA terminals, when re-accessing the cell network, the activation processing method adopted is the same as that adopted for the first access to the cell network, and no specific explanation is given here.

[0057] In one embodiment, after the target abnormal terminal re-accesses the network of the cell, the notifying the target abnormal terminal to re-access the network of the cell includes: determining the number of times the terminal that re-accesses the network of the cell is continuously determined as the target abnormal terminal within a preset time period; if the number of times the terminal that re-accesses the network of the cell is continuously determined as the target abnormal terminal within the preset time period is greater than the preset number, then after releasing the target abnormal terminal, prohibiting the target abnormal terminal from re-accessing the network of the cell; if the number of times the terminal that re-accesses the network of the cell is continuously determined as the target abnormal terminal within the preset time period is not greater than the preset number, then after releasing the target abnormal terminal, notifying the target abnormal terminal to re-access the network of the cell.

[0058] The base station can count the number of times a terminal that re-accesses the cell network is continuously identified as a target abnormal terminal. If the number of times a terminal that re-accesses the cell network is continuously identified as a target abnormal terminal within a preset time period is greater than a preset number, then after releasing the target abnormal terminal, the target abnormal terminal is prohibited from accessing the cell network again to reduce the impact of the target abnormal terminal on other terminals in the cell.

[0059] If the terminal that re-accesses the cell network is continuously identified as a target abnormal terminal for no more than a preset number of times within a preset period of time, it can access the network again by re-establishing.

[0060] In specific implementations, to facilitate identification of terminals reconnecting to the cell network, the base station can mark the target abnormal terminal when releasing it. Furthermore, the preset period can also be implemented using a timer, where the value of the preset period can be determined based on the actual usage environment.

[0061] In one embodiment, when there are multiple target abnormal terminals, releasing the target abnormal terminals includes: determining terminal types of the multiple target abnormal terminals respectively, and determining release priorities for releasing the multiple target abnormal terminals according to the terminal types; and releasing the multiple target abnormal terminals in sequence according to the release priorities.

[0062] In order to reduce terminal misjudgment and ensure the use of target abnormal terminals, the terminal type of each target abnormal terminal can be determined separately, and then the release priority of the target abnormal terminal can be determined according to the terminal type. Multiple target abnormal terminals can be released in sequence according to the release priority.

[0063] The terminal types of target abnormal terminals can include guaranteed bit rate terminals (GBR terminals) and non-guaranteed bit rate terminals (NGBR terminals). For example, a terminal that is performing guaranteed bit rate services such as video and voice services is a GBR terminal, while a terminal that is performing non-guaranteed bit rate services such as web browsing is an NGBR terminal.

[0064] During the specific implementation process, the normal services of GBR terminals can be guaranteed first, and the normal services of NGBR terminals can be guaranteed secondly. That is, the release priority of GBR terminals is lower, and the release priority of NGBR terminals is higher.

[0065] For example, the specific process can be as follows:

[0066] First, the terminal type of each target abnormal terminal is determined and classified into GBR terminals and NGBR terminals.

[0067] Then, in order to prioritize the normal operation of the GBR terminal, the release priority of the target abnormal terminal of the GBR terminal type is adjusted to the lowest.

[0068] For target abnormal terminals of the NGBR terminal type, they are sorted from high to low according to the scheduling priority of each target abnormal terminal, starting from the lowest priority. That is, the higher the scheduling priority, the lower the release priority.

[0069] The release priorities of the target abnormal terminals are sorted according to the above rules, and then the release processing is carried out in sequence from the target abnormal terminals with low priorities.

[0070] The above embodiment provides a network performance optimization method that uses the cell's performance indicators to determine whether there are potential abnormal terminals in the cell. When there are potential abnormal terminals in the cell, power control screening is performed on the terminals in the cell to determine the target abnormal terminal. Finally, the target abnormal terminal is released and then reconnected to the cell's network, completing the processing and reconnection of the target abnormal terminal. Through two screenings based on performance indicators and power control, the target abnormal terminal that affects the network in the cell is determined, and then the target abnormal terminal is released from the network. After release, the target abnormal terminal is reconnected to the network, reducing the impact on the network in the cell and ensuring the network experience of other users in the network. At the same time, reconnecting the target abnormal terminal to the network also ensures the network experience of users using the target abnormal terminal.

[0071] Please refer to Figure 2 , Figure 2 It is a flowchart of another network performance optimization method provided by an embodiment of the present invention.

[0072] like Figure 2 As shown, the network performance optimization method includes steps S201 to S205.

[0073] S201: Determine whether there is a potential abnormal terminal in the cell based on the performance indicators of the cell.

[0074] When a potential abnormal terminal exists in a cell, its terminal performance indicators may be abnormal, further affecting the cell performance indicators. Therefore, the cell performance indicators can be used to make a preliminary judgment on whether there is a potential abnormal terminal in the cell. A potential abnormal terminal refers to a terminal with potential power outage.

[0075] In one embodiment, the performance indicators include cell performance indicators and terminal performance indicators. A preliminary determination can be made based on the cell performance indicators to determine whether a potential abnormal terminal exists in the cell. If the cell performance indicators do not meet preset indicator conditions, a determination can be made based on the terminal performance indicators of the terminals in the cell to determine whether a potential abnormal terminal exists in the cell. If the terminal performance indicators of the terminals in the cell are abnormal, it can be determined that a potential abnormal terminal exists in the cell.

[0076] S202: If there is a potential abnormal terminal in the cell, determine a terminal to be controlled from the terminals in the cell based on power information of the terminals in the cell.

[0077] After identifying a potential abnormal terminal within a cell, the base station obtains power information from each terminal within the cell, including received signal strength and / or signal-to-noise ratio. Based on this power information, the base station identifies terminals to be controlled. These terminals require the base station to send power control commands for transmit power control.

[0078] For example, terminals with a signal-to-noise ratio greater than the target signal-to-noise ratio threshold and terminals with a received signal strength greater than or equal to a preset threshold can be used as terminals to be controlled. The base station needs to reduce the power of such high-power terminals, that is, send a power reduction command to such terminals.

[0079] For another example, a terminal whose signal-to-noise ratio is less than the target signal-to-noise ratio threshold and whose received signal strength is less than or equal to the preset threshold can also be used as a terminal to be controlled. The base station needs to increase the power of such low-power terminals, that is, send a power increase command to such terminals.

[0080] For terminals whose signal-to-noise ratio and received signal strength are in other ranges, the base station does not perform power control on such terminals, and therefore such terminals are not terminals to be controlled.

[0081] The target signal-to-noise ratio threshold and the preset threshold of the received signal strength are both configurable parameters of the base station.

[0082] S203: Perform power control screening on the terminals to be controlled and determine target abnormal terminals.

[0083] After identifying the terminals to be controlled, the base station sends power adjustment commands to them, performing power control screening to identify abnormal terminals. Power control screening involves the base station sending power control commands to terminals within a cell, thereby controlling the terminals' transmit power adjustments and screening based on the terminals' transmit power adjustments.

[0084] In one embodiment, see Figure 3 , is a schematic flowchart of the sub-steps of step S203, where step S203 specifically includes steps S2031 to S2033.

[0085] S2031: Perform transmit power control on the terminal to be controlled based on the power information of the terminal to be controlled, and determine a control type and control times of the transmit power control.

[0086] According to the power information of the terminal to be controlled, a corresponding transmit power control command is sent to the terminal to be controlled, so as to control the terminal to be controlled to adjust the transmit power.

[0087] For example, for a high-power terminal, a command to reduce power may be sent to the terminal, that is, TPC=-1.

[0088] For another example, for a low-power terminal, a power increase command can be sent to it, that is, TPC = 1. However, it should be noted that when sending a power increase command to such a terminal, the maximum transmit power of the terminal needs to be considered. That is, when the base station sends a power increase command, the maximum power increased cannot exceed the maximum transmit power of the terminal.

[0089] After the base station sends a transmit power control command to the terminal to be controlled, the control type and control frequency of the transmit power control command sent to the terminal to be controlled can be counted. The control type includes power increase and power decrease, and the control frequency is the number of times the transmit power control command is sent to the terminal to be controlled.

[0090] During specific implementation, the control type and the number of times of continuous transmission power control on the terminal to be controlled within a time window may be counted.

[0091] S2032: If the control types of the transmit power control are the same and the number of controls is greater than a preset number, determine a transmit power difference between two consecutive power adjustments of the terminal to be controlled.

[0092] If the control type of the transmission power control command sent by the base station to the terminal to be controlled is the same and the number of controls is greater than the preset number, it can be considered that the terminal to be controlled may not be controlled by the transmission power control command sent by the base station. Then, by determining the difference in transmission power after two adjacent power adjustments of the terminal to be controlled, it is determined whether the terminal to be controlled is the target abnormal terminal.

[0093] For example, if the base station continuously sends a transmit power control instruction to increase the power to the terminal to be controlled within a time window, and counts the number of times the base station sends the transmit power control instruction, and the control number obtained by counting is greater than the preset number, it can be considered that the terminal to be controlled may not be controlled by the transmit power control command sent by the base station, so as to facilitate further determination through the transmit power difference.

[0094] Similarly, if the base station continuously sends transmission power control instructions to lower the power to the terminal to be controlled within a time window, and counts the number of times the base station sends the transmission power control instructions, and the number of control times obtained by counting is greater than the preset number, it can be considered that the terminal to be controlled may not be controlled by the transmission power control command sent by the base station, so as to facilitate further determination through the transmission power difference.

[0095] If the base station sends multiple types of transmit power control instructions to a terminal within a time window, for example, after sending a transmit power control instruction to increase power, the terminal is then sent a transmit power control instruction to decrease power. The terminal is considered to be in a normal power control process and is considered normal. The transmit power difference for the terminal is no longer determined.

[0096] S2033: Determine a target abnormal terminal from the terminals to be controlled according to the transmit power difference.

[0097] The transmit power difference between two consecutive power adjustments of the terminal to be controlled is calculated, and then a target abnormal terminal is determined from the terminals to be controlled according to the transmit power difference.

[0098] In one embodiment, determining a target abnormal terminal from the terminals to be controlled according to the transmit power difference includes: if the absolute value of the transmit power difference is less than a preset value, determining the terminal to be controlled as the target abnormal terminal.

[0099] The transmit power difference is the difference between the transmit power values ​​of the terminal to be controlled after two adjacent transmit power adjustments. Therefore, if the absolute value of the transmit power difference of the terminal to be controlled is less than the preset value, it can be considered that the terminal to be controlled has no response to the transmit power command of the base station, and the terminal can be determined as a target abnormal terminal.

[0100] In the specific implementation process, in order to reduce errors in small-scale transmit power adjustment and terminal radio frequency reasons, when the absolute value of the transmit power difference of the terminal to be controlled is less than the preset value for multiple consecutive times, the terminal to be controlled can be determined as a target abnormal terminal.

[0101] S204: Release the target abnormal terminal and notify the target abnormal terminal to re-access the cell's network.

[0102] Since the impact of the target abnormal terminal on other terminals in the network will be effectively alleviated after being released and re-accessing the network, after determining the target abnormal terminal, the target abnormal terminal can be released and notified to re-access the cell network after the release.

[0103] For NSA terminals (non-independent networking terminals), the base station can directly notify the terminal to deactivate 5G, and the base station re-issues the measurement configuration. After meeting the measurement threshold, the terminal reports the measurement report and rejoins the 5G network.

[0104] For SA terminals (standalone networking terminals), the terminals can rejoin the 5G network by re-establishing.

[0105] It should be noted that for NSA terminals and SA terminals, when re-accessing the cell network, the activation processing method adopted is the same as that adopted for the first access to the cell network, and no specific explanation is given here.

[0106] The network performance optimization method provided in the above embodiment determines whether there are potential abnormal terminals in the cell by utilizing the performance indicators of the cell. When there are potential abnormal terminals in the cell, the potential abnormal terminals in the cell are determined based on the terminal performance indicators to obtain the potential abnormal terminals in the cell. Then, based on the power information of the potential abnormal terminals, the terminals to be controlled are determined from the set of potential abnormal terminals, and the terminals to be controlled are subjected to power control screening to determine the target abnormal terminal. Finally, the target abnormal terminal is released and notified to re-access the cell network. By determining the target abnormal terminal from the cell through layer-by-layer screening, the efficiency of determining the target abnormal terminal is improved, thereby improving the efficiency of optimizing network performance. At the same time, the released target abnormal terminal is re-accessed to the network, which, on the one hand, reduces the impact on the network and ensures the network experience of other users in the network, and on the other hand, ensures the network experience of users using the target abnormal terminal.
