Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The flow diagrams depicted in the figures are merely illustrative and do not necessarily include all of the elements and operations/steps, nor do they necessarily have to be performed in the order depicted. For example, some operations/steps may be decomposed, combined or partially combined, so that the actual execution sequence may be changed according to the actual situation.

It is to be understood that the terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used in the specification of the present invention and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.

The wireless network of the cellular mobile communication system is composed of a base station and terminals, a plurality of terminals are simultaneously served in the coverage area of one base station, and the uplink transmitting power of the terminals is more accurately adjusted by optimizing uplink closed-loop power control, so that the interference among cells is reduced, and the aim of improving the overall network performance is fulfilled. However, in an external field large capacity scene, a terminal whose transmission power is out of control often occurs, that is, an abnormal terminal whose transmission power cannot be adjusted through a normal power control flow of a base station, and the occurrence of such an abnormal terminal can raise the background noise level of the whole network, and finally can submerge useful signals of the existing network, which can cause serious influence on the overall network performance and experience of other users.

Therefore, embodiments of the present invention provide a network performance optimization method, a network performance optimization device, and a storage medium, where a target abnormal terminal is screened from a network, and the screened target abnormal terminal is processed, so as to achieve the purposes of improving network performance and optimizing network performance.

Some embodiments of the invention are described in detail below with reference to the accompanying drawings. The embodiments described below and the features of the embodiments can be combined with each other without conflict.

Referring to fig. 1, fig. 1 is a flowchart illustrating a network performance optimization method according to an embodiment of the present invention.

As shown in fig. 1, the network performance optimization method includes steps S101 to S103.

Step S101, determining whether a potential abnormal terminal exists in the cell based on the performance index of the cell.

When a potentially abnormal terminal exists in a cell, the performance index of the potentially abnormal terminal is abnormal, and the performance index of the cell is further affected, so that whether the potentially abnormal terminal exists in the cell can be preliminarily judged through the performance index of the cell. Wherein, the potentially abnormal terminal refers to a terminal with potential power runaway.

In one embodiment, the performance indicators include a cell performance indicator and a terminal performance indicator; determining whether a potential abnormal terminal exists in a cell based on the performance index of the cell, comprising: determining whether the cell performance index meets a preset index condition; if the cell performance index does not meet the preset index condition, determining whether the terminal performance index of the terminal in the cell is normal; and if the terminal performance index of the terminal in the cell is abnormal, determining that a potentially abnormal terminal exists in the cell.

The cell performance index refers to an overall performance index of the cell, such as received signal strength, interference noise, and throughput of the cell. Here, the received signal strength of a cell refers to the received power of the entire bandwidth, and the sum of the power of a useful signal and the power of noise is referred to without distinguishing a control channel from a traffic channel. The interference noise refers to noise generated when the whole bandwidth is loaded with a service, specifically, refers to average interference noise of each RB of the whole bandwidth, and the RB is a resource unit allocated to a service channel resource. The calculation of throughput depends on the power index, and is related to bandwidth, number of users, and frame structure, which is not limited herein.

The terminal performance index refers to the terminal performance index of each terminal in the cell, for example, the useful signal strength of the terminal. The useful signal strength of the terminal is related to the received signal strength, the number of antennas, the bandwidth, and the like, and is not limited herein, and the useful signal strength of the terminal may be calculated based on the above information.

Determining whether the cell performance index meets a preset index condition, if the cell performance index does not meet the preset index condition, determining that a potentially abnormal terminal may exist in the cell, determining the terminal performance index of the terminal in the cell, and when the terminal performance index of the terminal in the cell is abnormal, determining that the potentially abnormal terminal exists in the cell.

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

In one embodiment, the terminal performance indicators include a desired received signal strength; determining whether the terminal performance index of the terminal in the cell is normal, including: judging whether the useful received signal strength of the terminal in the cell is within a preset range or not; and if the useful received signal strength of the terminal in the cell is not in the preset range, determining that the terminal performance index of the terminal in the cell is abnormal.

The change of the terminal performance index of the terminal in the cell can affect the cell performance index of the cell, so the terminal performance index of the terminal in the cell can be converted according to the cell performance index meeting the preset index condition to ensure the normal cell performance index. And regarding the numerical range corresponding to the terminal performance index of the terminal in the cell, taking the numerical range as a preset range.

Because the terminal performance index includes the useful received signal strength, when the useful received signal strength of the terminal in the cell is within the preset range, the terminal performance index of the terminal is considered to be normal at the moment, and the terminal is in a controllable state. And if the useful received signal strength of the terminal in the cell is not within the preset range, determining that the terminal performance index of the terminal is abnormal at the moment.

In a specific implementation process, in order to reduce the misjudgment of a potentially abnormal terminal, it may be determined that the terminal performance index of the terminal is abnormal only when the useful received signal strength of the terminal in the cell is continuously and repeatedly out of the preset range. Wherein, the continuous times refer to two times or more.

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 cases, which are: 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 is less than the minimum value of the preset range once.

In order to reduce the misjudgment of the potentially abnormal terminal, at this time, the terminal performance index of the terminal is considered to be abnormal only under two conditions that 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.

And S102, if the potential abnormal terminal exists in the cell, performing power control screening on the terminal in the cell, and determining a target abnormal terminal.

And after determining that the potential abnormal terminal exists in the cell, performing power control screening on the terminal in the cell so as to determine a target abnormal terminal. The power control screening means that the base station sends a power control command to the terminal in the cell so as to control the terminal in the cell to adjust the transmission power, and the screening is performed according to the adjustment condition of the terminal to the transmission power.

In an embodiment, before performing power control screening on terminals in a cell, the method includes: determining a terminal to be controlled from terminals in a cell based on power information of the terminals in the cell; carrying out power control screening on terminals in a cell, comprising the following steps: and carrying out power control screening on the terminal to be controlled.

After determining that a potentially abnormal terminal exists in the cell, the base station side can acquire the acquired power information of each terminal in the cell, wherein the power information comprises the received signal strength and/or the signal to noise ratio. And determining the terminal to be controlled according to the power information of each terminal. The terminal to be controlled is a terminal which needs the base station to send a power control command to control the transmission power.

For example, a terminal with a signal-to-noise ratio greater than a target signal-to-noise ratio threshold may be used as a terminal to be controlled, and the base station needs to perform power reduction processing on the high-power terminal, that is, send a power reduction command to the terminal.

For another example, a terminal whose received signal strength is greater than or equal to a preset threshold may be used as a terminal to be controlled, and the base station needs to perform power reduction processing on the high-power terminal, that is, send a command for reducing power to the terminal.

For another example, a terminal whose signal-to-noise ratio is smaller than the target signal-to-noise ratio threshold and whose received signal strength is smaller than or equal to the preset threshold may also be used as a terminal to be controlled, and the base station needs to perform power boosting processing on the low-power terminal, that is, send a power up command to the terminal. However, it should be noted that when the command for adjusting the power up is sent to the terminal of this type, the maximum transmission power of the terminal needs to be considered, that is, when the base station sends the command for adjusting the power up, the maximum power of the power up cannot exceed the maximum transmission power of the terminal.

After the terminal to be controlled is determined, the base station sends a power adjustment command to the terminal to be controlled, and performs power control screening on the terminal to be controlled according to a response of the terminal to be controlled based on the power adjustment command.

In an embodiment, performing power control screening on terminals in a cell to determine a target abnormal terminal includes: determining a transmitting power difference value after adjusting transmitting power of two adjacent terminals in a cell; and determining a target abnormal terminal from the terminals in the cell according to the transmitting power difference.

After the base station sends a power adjustment command to the terminal in the cell, the terminal in the cell adjusts the transmission power based on the power adjustment command, records the transmission power values of the terminal in the cell after adjusting the transmission power twice adjacently, calculates the difference value of the transmission power values of the terminal in the cell after adjusting the transmission power twice adjacently, and takes the difference value as the transmission power difference value of the terminal in the cell after adjusting the transmission power twice adjacently. Then, the target abnormal terminal can be determined from the terminals in the cell according to the transmitting power difference value.

In an embodiment, before determining a difference between transmission powers of two adjacent terminals in a cell after adjusting the transmission powers, the method includes: carrying out transmission power control on the terminals in the cell based on the power information of the terminals in the cell, and determining the control type and the control times of the transmission power control; determining a transmission power difference value after twice adjacent transmission power adjustments of terminals in a cell, comprising: and if the control types of the transmission power control are the same and the control times are more than the preset times, determining the transmission power difference value after the power adjustment is carried out twice by the adjacent terminals in the cell.

Wherein the power information comprises received signal strength and/or signal to noise ratio. The base station controls the transmitting power of the terminals in the cell according to the power information of each terminal, and after the base station sends a transmitting power control command to the terminal to be controlled, the control type and the control times of the transmitting power control command sent by the terminal to be controlled can be counted. The control type comprises up-regulation power and down-regulation power, and the control times are the times of sending a transmission power control command to the terminal to be controlled.

If the control types of the transmission power control commands sent by the base station to the terminal to be controlled are the same and the control times are greater than the preset times, the terminal to be controlled is considered to be possibly not controlled by the transmission power control commands sent by the base station, and whether the terminal to be controlled is a target abnormal terminal is determined by determining the transmission power difference value of the terminal to be controlled after power adjustment is carried out twice in the vicinity.

Since the target abnormal terminal is a terminal whose transmission power is out of control, in an embodiment, determining the target abnormal terminal from terminals in the cell according to the transmission power difference includes: and if the absolute value of the difference value of the transmitting powers is smaller than the preset value, determining the terminal in the cell as a target abnormal terminal.

The difference value of the transmitting power is the difference value of the transmitting power values of the terminals in the cell after the transmitting power adjustment is performed twice, therefore, if the absolute value of the difference value of the transmitting power of the terminal is less than the preset value, the terminal can be determined as the target abnormal terminal if the terminal does not respond to the transmitting power command of the base station.

In a specific implementation process, in order to reduce errors caused by adjustment of small-scale transmission power, radio frequency reasons of the terminal and the like, when an absolute value of a transmission power difference value of the terminal is continuously smaller than a preset value for multiple times, the terminal can be determined as a target abnormal terminal. In the specific implementation process, the theoretical value of the preset value is 0, that is, the transmission power value of the terminal in the cell after the transmission power adjustment is performed twice in adjacent time is not changed. However, in the actual use process, the preset value may be set to a value greater than 0 due to errors such as the fluctuation of the transmission power of the terminal in the cell and the radio frequency cause of the terminal, and the selection of the specific value may be determined empirically.

S103, releasing the target abnormal terminal, and informing the target abnormal terminal to re-access the network of the cell.

After the target abnormal terminal is released and re-accessed to the network, the performance of the power abnormality of the target abnormal terminal is greatly weakened, and in most cases, the performance index of the whole cell of the cell is not influenced, the experience of other terminal users in the network is not greatly influenced, that is, the influence on other terminals in the network is effectively relieved.

For an NSA terminal (non-independent networking terminal), the base station can directly inform the terminal to deactivate the 5G, and the base station retransmits the measurement configuration, and the terminal reports the measurement report after meeting the measurement threshold and rejoins the 5G network.

For the SA terminal (independent networking terminal), the terminal can be added with the 5G network in a reestablishing mode.

It should be noted that, for the NSA terminal and the SA terminal, when the network of the cell is re-accessed, the activation processing method is the same as that adopted when the network of the cell is initially accessed, and is not specifically described here.

In an 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 times that a terminal re-accessing a network of a cell is continuously determined as a target abnormal terminal within a preset time period; if the number of times that the terminal re-accesses the network of the cell is continuously determined to be the target abnormal terminal in a preset time period is larger than the preset number of times, after the target abnormal terminal is released, the target abnormal terminal is forbidden to re-access the network of the cell; and if the number of times that the terminal re-accesses the network of the cell is continuously determined to be the target abnormal terminal in the preset time period is not more than the preset number of times, releasing the target abnormal terminal and then informing the target abnormal terminal to re-access the network of the cell.

The base station can count the times of continuously determining the terminal re-accessed to the cell network as the target abnormal terminal again, if the times of continuously determining the terminal re-accessed to the cell network as the target abnormal terminal in the preset time period is more than the preset times, after releasing the target abnormal terminal, forbidding the target abnormal terminal to re-access to the cell network so as to reduce the influence of the target abnormal terminal on other terminals in the cell.

If the number of times that the terminal re-accesses the cell network is continuously determined as the target abnormal terminal in the preset time period is not more than the preset number of times, the re-access to the cell network can be established through reconstruction.

In the specific implementation process, in order to facilitate the base station to identify the terminal re-accessing the cell network, the target abnormal terminal may be marked when the target abnormal terminal is released. And the preset time period can also be realized by a timer, wherein the numerical value of the preset time period can be determined according to the actual use environment.

In an embodiment, when there are a plurality of target abnormal terminals, releasing the target abnormal terminal includes: respectively determining the terminal types of a plurality of target abnormal terminals, and determining the release priority for releasing the plurality of target abnormal terminals according to the terminal types; and sequentially releasing the plurality of target abnormal terminals according to the release priority.

In order to reduce terminal misjudgment and ensure the use of the target abnormal terminals, the terminal type of each target abnormal terminal can be respectively determined, then the release priority of the target abnormal terminal is determined according to the terminal type, and a plurality of target abnormal terminals are sequentially released according to the release priority.

The terminal types of the target abnormal terminal may include a guaranteed bit rate terminal (GBR terminal) and a non-guaranteed bit rate terminal (NGBR terminal), among others. For example, a terminal that is performing guaranteed bit rate services such as video and voice services is a GBR terminal, and a terminal that is performing non-guaranteed bit rate services such as data services for browsing a web page is an NGBR terminal.

In the specific implementation process, the GBR terminal service can be guaranteed to be normal preferentially, and the NGBR terminal service is guaranteed to be normal secondarily, that is, the GBR terminal has a lower release priority and the NGBR terminal has a higher release priority.

For example, the specific process may be as follows:

firstly, determining the terminal type of each target abnormal terminal, and classifying according to GBR terminals and NGBR terminals.

And then, in order to preferentially ensure that the GBR terminal service is normal, the release priority of the target abnormal terminal of the GBR terminal type is adjusted to be the lowest.

For the target abnormal terminals of the NGBR terminal type, the scheduling priority of each target abnormal terminal is sequenced from high to low from low priority, namely the higher the scheduling priority is, the lower the release priority is.

And sequencing the release priorities of the target abnormal terminals according to the rules, and then sequentially performing release processing on the target abnormal terminals with low priorities.

In the method for optimizing network performance provided in the foregoing embodiment, it is determined whether a potentially abnormal terminal exists in a cell by using a performance index of the cell, and when the potentially abnormal terminal exists in the cell, power control screening is performed on terminals in the cell, a target abnormal terminal is determined, the target abnormal terminal is released, and then the target abnormal terminal is re-accessed to a network of the cell, so as to complete processing and re-access of the target abnormal terminal. Through twice screening based on performance indexes and power control, a target abnormal terminal influencing a network in a cell is determined, then the target abnormal terminal is released from the network, and the target abnormal terminal is re-accessed into the network after release, so that the influence on the network in the cell is reduced, the network experience of other users in the network is ensured, and meanwhile, the network experience of the user using the target abnormal terminal is also ensured by re-accessing the target abnormal terminal into the network.

Referring to fig. 2, fig. 2 is a flowchart illustrating another network performance optimization method according to an embodiment of the present invention.

As shown in fig. 2, the network performance optimization method includes steps S201 to S205.

S201, determining whether a potential abnormal terminal exists in the cell based on the performance index of the cell.

In an embodiment, the performance indicators include a cell performance indicator and a terminal performance indicator. Whether a potential abnormal terminal possibly exists in the cell can be preliminarily judged based on the cell performance index, when the cell performance index of the cell does not meet the preset index condition, whether the potential abnormal terminal exists in the cell is judged according to the terminal performance index of the terminal in the cell, and if the terminal performance index of the terminal in the cell is abnormal, the potential abnormal terminal exists in the cell can be considered.

S202, if the potential abnormal terminal exists in the cell, the terminal to be controlled is determined from the terminals in the cell based on the power information of the terminals in the cell.

After determining that a potentially abnormal terminal exists in a cell, the base station side can acquire the acquired power information of each terminal in the cell, wherein the power information comprises received signal strength and/or signal to noise ratio. And determining the terminal to be controlled according to the power information of each terminal. The terminal to be controlled is a terminal which needs the base station to send a power control command to control the transmission power.

For example, a terminal with a signal-to-noise ratio greater than a target signal-to-noise ratio threshold and a terminal with a received signal strength greater than or equal to a preset threshold may be both used as a terminal to be controlled, and a base station needs to perform power reduction processing on the high-power terminal, that is, send a power down command to the terminal.

For another example, a terminal whose signal-to-noise ratio is smaller than the target signal-to-noise ratio threshold and whose received signal strength is smaller than or equal to the preset threshold may also be used as a terminal to be controlled, and the base station needs to perform power boosting processing on the low-power terminal, that is, send a power up command to the terminal.

For terminals with signal-to-noise ratios and received signal strengths in other range intervals, the base station does not perform power control on the terminals, and therefore the terminals are not terminals to be controlled.

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

And S203, performing power control screening on the terminal to be controlled, and determining a target abnormal terminal.

After the terminal to be controlled is determined, the base station sends a power adjustment command to the terminal to be controlled, and then performs power control screening on the terminal to be controlled to determine a target abnormal terminal. The power control screening means that the base station sends a power control command to the terminal in the cell so as to control the terminal in the cell to adjust the transmission power, and the screening is performed according to the adjustment condition of the terminal to the transmission power.

In an embodiment, please refer to fig. 3, which is a schematic flowchart of the sub-steps of step S203, and step S203 specifically includes step S2031 to step S2033.

S2031, based on the power information of the terminal to be controlled, the terminal to be controlled is controlled by the transmission power, and the control type and the control times of the transmission power control are determined.

And sending a corresponding transmission power control command to the terminal to be controlled according to the power information of the terminal to be controlled so as to control the terminal to be controlled to adjust the transmission power.

For example, for a high power terminal, a command to turn down the power may be sent to it, i.e., TPC ═ 1.

For another example, for a low power terminal, a command to increase power may be sent thereto, i.e., TPC ═ 1. However, it should be noted that when the command for adjusting the power up is sent to the terminal of this type, the maximum transmission power of the terminal needs to be considered, that is, when the base station sends the command for adjusting the power up, the maximum power of the power up cannot exceed the maximum transmission power of the terminal.

After the base station sends the transmission power control command to the terminal to be controlled, the control type and the control times of the transmission power control command sent by the terminal to be controlled can be counted. The control type comprises up-regulation power and down-regulation power, and the control times are the times of sending a transmission power control command to the terminal to be controlled.

In the specific implementation process, the control type and the control times of continuously performing the transmission power control on the terminal to be controlled within a time window can be counted.

S2032, if the control types of the transmission power control are the same and the control times are more than the preset times, determining the transmission power difference value of the terminal to be controlled after the power adjustment is performed twice.

For example, if the base station continuously sends the transmit power control command for increasing the power to the terminal to be controlled within a time window, and counts the number of times that the base station sends the transmit power control command, and when the counted number of times is greater than the preset number of times, it may be determined that the terminal to be controlled may not be controlled by the transmit power control command issued by the base station, so as to further determine the terminal to be controlled by the transmit power difference.

Similarly, if the base station continuously sends the transmission power control command for reducing the power to the terminal to be controlled in a time window, and counts the number of times that the base station sends the transmission power control command, and when the counted number of times is greater than the preset number of times, it is determined that the terminal to be controlled may not be controlled by the transmission power control command sent by the base station, so as to further determine the terminal to be controlled by the transmission power difference.

If the base station sends the transmission power control instruction of multiple control types to the terminal to be controlled in a time window, for example, after sending the transmission power control instruction of power up-regulation to the terminal to be controlled, sending the transmission power control instruction of power down-regulation to the terminal to be controlled. The terminal to be controlled is considered to be performing a normal power control process, the terminal to be controlled is determined to be a normal terminal, and the transmission power difference of the terminal to be controlled is not determined any more.

S2033, determining a target abnormal terminal from the terminals to be controlled according to the transmitting power difference.

And calculating a transmitting power difference value after the power of the terminal to be controlled is adjusted twice, and determining a target abnormal terminal from the terminal to be controlled according to the transmitting power difference value.

In one embodiment, determining a target abnormal terminal from terminals to be controlled according to a transmission power difference includes: and if the absolute value of the transmitting power difference is smaller than the preset value, determining the terminal to be controlled as a target abnormal terminal.

The transmission power difference is the difference between the transmission power values of the two adjacent times of the terminal to be controlled after the transmission power adjustment, therefore, if the absolute value of the transmission power difference of the terminal to be controlled is smaller than the preset value, the terminal to be controlled is considered to have no response to the transmission power command of the base station, and the terminal can be determined as a target abnormal terminal.

In a specific implementation process, in order to reduce errors of adjustment of small-scale transmission power, radio frequency reasons of the terminal, and the like, when an absolute value of a transmission power difference value of the terminal to be controlled is continuously smaller than a preset value for multiple times, the terminal to be controlled may be determined as a target abnormal terminal.

S204, releasing the target abnormal terminal, and informing the target abnormal terminal to re-access the network of the cell.

After the target abnormal terminal is released and re-accessed to the network, the influence on other terminals in the network can be effectively relieved, so that after the target abnormal terminal is determined, the target abnormal terminal can be released, and the released target abnormal terminal is informed to re-access to the network of the cell after the release.

In the network performance optimization method provided in the foregoing embodiment, whether a potential abnormal terminal exists in a cell is determined by using a performance index of the cell, when the potential abnormal terminal exists in the cell, the potential abnormal terminal in the cell is determined based on the performance index of the terminal to obtain the potential abnormal terminal in the cell, then a terminal to be controlled is determined from a set of potential abnormal terminals based on power information of the potential abnormal terminal, power control screening is performed on the terminal to be controlled, a target abnormal terminal is determined, the target abnormal terminal is finally released, and the target abnormal terminal is notified to re-access the network of the cell. The target abnormal terminal is determined from the cell in a layer-by-layer screening mode, the efficiency of determining the target abnormal terminal is improved, the efficiency of optimizing the network performance is further improved, and meanwhile, the released target abnormal terminal is re-accessed into the network, so that on one hand, the influence on the network is reduced, the network experience of other users in the network is guaranteed, and on the other hand, the network experience of the user using the target abnormal terminal is also guaranteed.
