Please refer to FIG. 2, which shows a flowchart of a method for determining network quality provided by an exemplary embodiment of the present application. This embodiment is described by taking the method being executed by a terminal device as an example, and the method includes the following steps:

Step 201: Acquire uplink transmission parameters for data packet transmission in the uplink and downlink transmission parameters for data packet transmission in the downlink.

The uplink refers to the channel through which the terminal device sends data, and the downlink refers to the channel through which the terminal device receives data.

In the embodiment of the present application, the terminal device will acquire uplink transmission parameters when transmitting data in the uplink and downlink transmission parameters when transmitting data in the downlink, so as to evaluate the network quality according to the uplink transmission parameters and the downlink transmission parameters.

In a possible implementation manner, the terminal device obtains uplink transmission parameters and downlink transmission parameters during the process of the user using the data service, and evaluates the network quality in time, so as to adjust the network according to the evaluated network quality to avoid network quality Poor impact on data services. Optionally, the terminal device may perform sampling with a target duration as a period, that is, acquire uplink transmission parameters and downlink transmission parameters within the target duration. Illustratively, the target duration may be 1 s, and the terminal device may use 1 s as a period to obtain uplink transmission parameters and downlink transmission parameters in the history of 1 s to evaluate the network quality.

Step 202: Determine the uplink quality score of the uplink based on the uplink transmission parameter and the downlink transmission parameter according to the uplink scoring method.

In a possible implementation manner, the terminal device evaluates the quality of the uplink and the quality of the downlink respectively. The uplink corresponds to an uplink scoring method, and the uplink scoring method is used to indicate a method for evaluating the uplink quality by using a transmission parameter. When the transmission parameters are acquired, the terminal device can determine the uplink quality score corresponding to the uplink according to the uplink scoring method.

During the uplink transmission process, the downlink transmission may have an impact on the uplink transmission, and the uplink quality score is determined only based on the uplink transmission parameters of the uplink, and the quality of the uplink cannot be accurately evaluated. Therefore, When the terminal equipment determines the uplink quality score, it will use the uplink transmission parameters and the downlink transmission parameters to jointly determine.

Step 203: Determine the downlink quality score of the downlink based on the uplink transmission parameter and the downlink transmission parameter according to the downlink scoring method.

Correspondingly, the downlink scoring method is used to indicate a method for evaluating downlink quality by using transmission parameters. When the transmission parameters are acquired, the terminal device may determine the downlink quality score corresponding to the downlink according to the downlink scoring method.

And in the process of downlink quality assessment, the downlink quality score is also jointly determined based on the uplink transmission parameter and the downlink transmission parameter to ensure the accuracy of the downlink quality score.

Step 204: Determine the network quality based on the uplink quality score and the downlink quality score.

In a possible implementation manner, the terminal device will use the uplink quality score and the downlink quality score to comprehensively evaluate the network quality.

Since both the uplink transmission parameters and the downlink transmission parameters are jointly determined in the process of determining the uplink quality score and the downlink quality score, the impact of the data interaction process between the uplink and the downlink on the transmission can be avoided. It is helpful to improve the accuracy of evaluating the uplink quality and downlink quality, and the terminal device can evaluate the current network quality based on the uplink quality and downlink quality, which can improve the determination of network quality. Accuracy of quality.

To sum up, in the embodiment of the present application, the terminal device uses the uplink transmission parameters of the uplink and the downlink transmission parameters of the downlink to evaluate the quality of the uplink and the quality of the downlink respectively, and obtain the uplink quality score and Downlink quality score, so as to determine the final network quality according to the uplink quality score and the downlink quality score. In the process of evaluating the uplink and downlink quality, both the uplink parameters and the downlink parameters are jointly evaluated, which can improve the accuracy of evaluating the actual data transmission quality of the uplink and downlink. Helps improve the accuracy of determining network quality.

Optionally, the terminal device evaluates the uplink quality according to the uplink scoring method, and evaluates the downlink quality according to the downlink scoring method. The uplink scoring method and the downlink scoring method will be schematically described in the following embodiments.

Please refer to FIG. 3 , which shows a flowchart of a method for determining network quality provided by another exemplary embodiment of the present application. This embodiment is described by taking the method being executed by a terminal device as an example. The method includes the following steps:

Step 301: Obtain uplink transmission parameters for data packet transmission in the uplink and downlink transmission parameters for data packet transmission in the downlink.

In the data transmission process, the transmission is usually performed by using a Transmission Control Protocol (Transmission Control Protocol, TCP). In a possible implementation manner, the uplink transmission parameters and the downlink transmission parameters are transmission parameters in the process of transmitting TCP data packets.

In the process of acquiring uplink transmission parameters and downlink transmission parameters, the terminal device can acquire the uplink transmission rate, uplink retransmission rate and uplink transmission delay of the TCP data packet in the uplink; correspondingly, the terminal device can acquire the TCP data packet in the uplink Downlink downlink transmission rate, downlink retransmission rate, and downlink transmission delay. Among them, the transmission rate is the number of data packets transmitted per second in the link; the retransmission rate is the number of normal TCP data packets transmitted in the link/(the number of normal TCP data packets + the number of retransmitted TCP data packets) ; The transmission delay is the average round trip time (Round TripTime, RTT) of the TCP data packet.

Step 302, in the case that the uplink transmission rate in the uplink transmission parameter is greater than the first rate threshold, determine the uplink quality score based on the uplink transmission parameter.

In the process of scoring according to the uplink scoring method, the terminal device will firstly evaluate the uplink quality with reference to the uplink transmission rate. Optionally, the uplink transmission parameter includes the uplink transmission rate of the TCP data packet. If the uplink transmission rate is high, it indicates that the uplink quality is good, and only the uplink transmission parameter can be used to determine the uplink quality score without referring to other parameters. transfer parameters. In one possible implementation, this step may include steps 302a-302b:

Step 302a, when the uplink transmission rate is greater than the first rate threshold, determine that the uplink reference score of the uplink is the highest score.

When the acquired uplink transmission rate is greater than the first rate threshold, it is determined that it is a higher rate scenario, and the uplink quality is good. Therefore, it can be determined that the uplink reference score of the uplink is the highest score. The first rate threshold is a preset value, for example, the first rate threshold is 240 data packets transmitted per second. In a possible implementation manner, the influence of the transmission rate, that is, the bandwidth, may be further used to determine the first rate threshold, that is, the first rate threshold is the product of the threshold and the bandwidth influence factor. Illustratively, the first rate threshold is 240*bandwidth impact factor. Wherein, the bandwidth impact factor represents the weight ratio of the impact of the transmission rate on the quality, for example, it may be 1.2.

Illustratively, as shown in Figure 4, the number of uplink packets per second is the uplink transmission rate. When the number of uplink packets per second > 240*bandwidth impact factor, it is determined as a high-rate scenario, and the uplink benchmark score is 100.

Step 302b: Determine the uplink quality score based on the uplink reference score and the uplink retransmission rate in the uplink transmission rate.

In the process of TCP data packet transmission, there may be a situation that the data packet transmission fails, in this case, the TCP data packet will be retransmitted, and when the TCP data packet retransmission rate is high, it indicates that the network quality is poor, so , the TCP retransmission rate needs to be considered when evaluating the quality. In a possible implementation manner, a retransmission rate influencing factor is pre-installed in the terminal device, which represents the influence weight on the quality evaluation. Illustratively, the retransmission rate influencing factor may be 0.8. After the retransmission rate is obtained, the retransmission rate impact score can be determined based on the product of the benchmark score, the retransmission rate, and the retransmission rate impact factor, so that the final quality score can be determined according to the benchmark score and the retransmission rate impact score.

That is, uplink quality score = uplink benchmark score - uplink benchmark score * uplink retransmission rate * retransmission rate impact factor. Illustratively, as shown in FIG. 4 , when the number of uplink packets per second>240*bandwidth impact factor, the uplink quality score=100-100*retransmission rate*retransmission rate impact factor.

Step 303, in the case that the uplink transmission rate is less than the first rate threshold, determine the uplink quality score based on the uplink transmission parameter and the downlink transmission parameter.

Optionally, in the case that the uplink transmission rate is less than the first rate threshold, it is determined as a lower rate scenario. In this case, it is necessary to further evaluate the uplink quality based on other transmission parameters. Optionally, in the case that the uplink transmission rate is less than the first rate threshold, performing quality assessment according to other transmission parameters may include the following situations:

1. When the uplink transmission delay in the uplink transmission parameters is less than the first delay threshold or greater than the second delay threshold, determine the uplink benchmark score of the uplink based on the uplink transmission delay, the uplink transmission delay and the uplink benchmark score negatively correlated.

When the uplink transmission rate is less than the first rate threshold, the terminal device further evaluates the quality according to the uplink transmission delay. The first delay threshold may be a preset threshold. Illustratively, the first delay threshold may be 400ms. When the uplink transmission delay is less than the first delay threshold, it indicates that the transmission delay is small, and the uplink benchmark score can be determined only based on the uplink transmission delay. In the case where the uplink transmission delay is smaller, the uplink benchmark score higher.

Further, in the case that the uplink transmission delay is less than the first delay threshold, the transmission delay may be divided into intervals. In the case that the uplink transmission delay is less than the fourth delay threshold, the uplink reference score may be determined as the first-level score, that is, the highest score. Illustratively, the fourth delay threshold is 200ms, and when the uplink transmission delay is less than 200ms, the uplink benchmark score is determined to be 100. When the uplink transmission delay is greater than the fourth delay threshold and less than the fifth delay threshold, the uplink reference score is determined to be the second-level score, which is lower than the first-level score. Wherein, the fourth delay threshold is smaller than the fifth delay threshold, and the fifth delay threshold is smaller than the first delay threshold. Illustratively, the fifth delay threshold is 300ms, and when the uplink transmission delay is greater than 200ms and less than 300ms, the uplink benchmark score is determined to be 80. When the uplink transmission delay is greater than the fifth delay threshold and less than the first delay threshold, the uplink reference score is determined to be a third-level score, which is smaller than the second-level score. Illustratively, when the uplink transmission delay is greater than 300ms and less than 400ms, the uplink benchmark score is determined to be 70.

In addition, when the uplink transmission delay is greater than the second delay threshold, it is determined that the delay is too large, indicating that the network quality is poor. Therefore, the uplink benchmark score can also be directly determined based on the uplink transmission delay. In the case that the uplink transmission delay is greater than the second delay threshold, the terminal device determines that the uplink benchmark score is the fourth-level score, that is, the lowest score. Illustratively, the second delay threshold may be 1000ms, and when the uplink transmission delay is greater than 1000ms, the uplink benchmark score is determined to be 59.

2. When the uplink transmission delay is greater than the first delay threshold and less than the second delay threshold, the uplink benchmark score is determined based on the downlink transmission rate in the downlink transmission parameter, and the downlink transmission rate is positively correlated with the uplink benchmark score.

When the uplink transmission delay is greater than the first delay threshold and less than the second delay threshold, it indicates that the transmission delay is relatively large. In this case, on the one hand, the delay may be large due to network reasons, and on the other hand, the transmission delay is the RTT of the TCP packet, where the RTT is the acknowledgement character (Acknowledge character, ACK) when the data packet is sent to the reception. )time. The ACK data is sent by the receiving end device to the terminal device. When more data packets are transmitted in the downlink, the ACK data transmission is slower, and accordingly, the RTT is larger. Therefore, when a large number of data packets are transmitted in the downlink, the uplink transmission delay may be relatively large, which is not caused by the network.

Therefore, in a possible implementation manner, when the uplink transmission delay is greater than the first delay threshold and less than the second delay threshold, the terminal device still needs to continue the downlink transmission delay, that is, every second in the downlink The number of transmitted data packets is used as a reference, and the uplink quality is evaluated to determine whether the uplink transmission delay is large due to network reasons. Among them, the downlink transmission rate is positively correlated with the uplink benchmark score. In the case of a larger downlink transmission rate, it indicates that there are more data packets transmitted in the downlink, indicating that the transmission delay may not be caused by network reasons, and the corresponding uplink benchmark score corresponding to the uplink is higher.

Optionally, in the case that the downlink transmission rate is greater than the third rate threshold, the uplink reference score is determined as the first grade score. The third rate threshold is greater than the first rate threshold, for example, the third rate threshold is 400 data packets transmitted per second. When the number of data packets per second corresponding to the downlink, that is, the number of downlink packets per second is greater than 400, the uplink benchmark score is determined to be 100.

Optionally, when the downlink transmission rate is greater than the first rate threshold and less than the third rate threshold, the uplink reference score is determined to be the second grade score. For example, when the number of downlink packets per second is greater than 240 and less than 400, the uplink benchmark score is determined to be 80.

Optionally, in the case that the downlink transmission rate is less than the first rate threshold, the uplink reference score is determined to be the fourth grade score. For example, when the number of downlink packets per second is less than 240, the uplink benchmark score is determined to be 59.

In a possible implementation manner, the uplink quality score is determined based on the uplink reference score and the uplink retransmission rate in the uplink transmission parameter.

When the uplink transmission rate is less than the first rate threshold, the terminal device determines and obtains the uplink reference score according to the uplink transmission delay and the downlink transmission rate, and then determines the final uplink quality score based on the uplink retransmission rate. For this method, reference may be made to the above-mentioned step 302b, which will not be repeated here.

Illustratively, as shown in FIG. 4 , when the uplink transmission rate, that is, the number of uplink packets per second is less than or equal to 240* the bandwidth impact factor, a second judgment is made based on the uplink transmission delay, that is, the uplink RTT. In the case of uplink RTT<200ms, determine the uplink quality score as 100-100*retransmission rate*retransmission rate impact factor; in the case of uplink 200ms<uplink RTT<300ms, determine the uplink quality score as 80-80*retransmission rate Transmission rate*retransmission rate impact factor; in the case of 300ms<uplink RTT<400ms, determine the uplink quality score as 70-70*retransmission rate*retransmission rate impact factor; in the case of uplink RTT>1000ms, determine the uplink quality score The quality score is 59-59*retransmission rate*retransmission rate impact factor. In the case of 400ms<uplink RTT<1000ms, it is necessary to further judge according to the downlink transmission rate, that is, the number of downlink packets per second. When the number of downlink packets per second > 400, determine the uplink quality score as 100-100 * retransmission rate * retransmission rate impact factor; in the case of 240 < number of downlink packets per second < 400, determine the uplink quality score as 80-80*retransmission rate*retransmission rate impact factor; when the number of downlink packets per second is less than 240, determine the uplink quality score as 59-59*retransmission rate*retransmission rate impact factor.

When the uplink transmission rate is less than the first rate threshold, there may be a situation where the uplink transmission rate is very small. In this case, it is necessary to further obtain other transmission parameters for quality evaluation. In this case, determining the uplink quality score may include the following: step:

Step 1. When the uplink transmission rate and the downlink transmission parameter are less than the second rate threshold, and the uplink transmission delay in the uplink transmission parameter is greater than the third delay threshold, determine that the uplink benchmark score of the uplink is the lowest score, where the second rate threshold is less than the first rate threshold.

In a possible implementation manner, when the uplink transmission rate is less than the second rate threshold, it is determined that the number of data packets transmitted in the uplink is less. Therefore, the second rate threshold is much smaller than the first rate threshold, and the second rate threshold may be 10 packets per second. When it is determined that the uplink transmission rate is less than the second rate threshold, the downlink transmission rate needs to be further determined. In the case that the downlink transmission rate is also less than the second rate threshold, it indicates that the current number of data packets transmitted is small, and no need for the current business scenario. Transmit more data packets, for example, in game business scenarios. In this scenario, the transmission delay is usually low, for example, about 100ms. If the transmission delay is high, it indicates that the network quality is poor. Therefore, after it is determined that both the uplink transmission rate and the downlink transmission rate are less than the second rate threshold, the uplink benchmark score is further determined according to the uplink transmission delay. In the case that the uplink transmission delay is greater than the third delay threshold, it is determined that the current transmission rate is low, and the uplink benchmark score is the fourth-level score, that is, the lowest score. For example, the third delay threshold is 170ms.

Step 2: Determine the uplink quality score based on the uplink benchmark score and the uplink retransmission rate in the uplink transmission parameter.

After the uplink benchmark score is obtained, the uplink retransmission rate is also used to determine the uplink quality score. For this method, reference may be made to the above steps, which will not be repeated here.

Schematically, as shown in Figure 4, in the case that the number of uplink packets per second<10&&the number of downlink packets per second<10&&uplink RTT>170ms, determine the uplink quality score as 59-59*retransmission rate*retransmission rate impact factor.

Step 304, in the case that the downlink transmission rate in the downlink transmission parameter is greater than the first rate threshold, determine the downlink quality score based on the downlink transmission parameter.

In the above steps, the uplink scoring method is exemplarily described. The downlink scoring method will be exemplarily described below. Similar to the uplink scoring method, the terminal device firstly evaluates the downlink quality with reference to the downlink transmission rate. When the acquired downlink transmission rate is greater than the first rate threshold, the terminal device determines that it is a higher rate scenario and the downlink quality is good, so the downlink reference score of the downlink can be determined to be the highest score.

After the downlink benchmark score is determined, the downlink quality score is further determined according to the downlink retransmission rate. Downlink quality score = downlink benchmark score - downlink benchmark score * downlink retransmission rate * retransmission rate impact factor.

Illustratively, as shown in Figure 5, when the number of downlink packets per second > 240*bandwidth impact factor, it is determined as a high-rate scenario, the downlink benchmark score is 100, and the downlink quality score is 100-100*retransmission rate* Retransmission rate impact factor.

Step 305: In the case that the downlink transmission rate is less than the first rate threshold, determine the downlink quality score based on the uplink transmission parameter and the downlink transmission parameter.

In the case where the downlink transmission rate is less than the first rate threshold, it is determined as a lower rate scenario, and the terminal device needs to further use the uplink transmission parameter and the downlink transmission parameter to determine the downlink quality score. This approach may include the following steps:

Step 305a: Determine the downlink reference score of the downlink based on the uplink transmission delay in the uplink transmission parameter, and the uplink transmission delay and the downlink reference score have a negative correlation.

When the downlink transmission rate is less than the first rate threshold, it is necessary to further judge according to the transmission delay. However, in the process of downlink data transmission, the terminal device is the receiver and cannot confirm the actual sending time, that is, the exact downlink transmission delay (downlink RTT) cannot be determined. Therefore, in a possible implementation, in the downlink When the transmission rate is less than the first rate threshold, the terminal device further performs downlink quality assessment according to the uplink transmission delay. In the case of the longer uplink transmission delay, the lower the downlink benchmark score is.

Optionally, in the case that the uplink transmission delay is greater than the first delay threshold, the downlink benchmark score is determined to be the fourth-level score; in the case that the uplink transmission delay is less than the first delay threshold, the downlink benchmark score is determined to be the fourth-level score. One grade rating.

Step 305b: Determine the downlink quality score based on the downlink reference score and the downlink retransmission rate in the downlink transmission parameter.

After the downlink benchmark score is determined, the downlink quality score is further determined according to the downlink retransmission rate.

Illustratively, as shown in Figure 5, in the case that the number of downlink packets per second is less than or equal to 240*bandwidth impact factor, if the uplink RTT>400ms, the downlink quality score is determined to be 59-59*retransmission rate*retransmission rate impact factor; if the uplink RTT≤400ms, the downlink quality score is determined to be 100-100*retransmission rate*retransmission rate impact factor (not shown in the figure).

In the process of data transmission, there is a packet loss situation. Whenever a packet loss situation occurs, the data packet needs to be retransmitted, which will increase the transmission delay. Conduct quality assessments. In this way, the downlink quality score=downlink benchmark score-2*packet loss*RTT/1000.

As shown in Figure 5, when the uplink RTT≤400ms, the downlink quality score is 100-2*packet loss*RTT/1000.

Step 306: Determine the quality level of the network quality based on the lowest score among the uplink quality score and the downlink quality score.

After the uplink quality score and the downlink quality score are obtained, the network quality level can be determined according to the lowest score among the uplink quality score and the downlink quality score. Wherein, the corresponding relationship between different scores and quality levels is pre-stored in the terminal device, and after the lowest score is determined, the quality level corresponding to the lowest score may be determined as the quality level of the current network quality.

Illustratively, the corresponding relationship between scores and quality levels is shown in Table 1:

Table 1

score quality level 80-100 excellent 60-80 medium 40-60 poor <40 Difference

With reference to the example in Table 1, when it is determined that the uplink quality score is 90 and the downlink quality score is 70, the quality level of the network quality is determined according to the downlink quality score of 70, and the quality level is medium.

In this embodiment, the link quality is first evaluated based on the transmission rate. When the transmission rate is high, it is not necessary to perform the evaluation based on other parameters. Delaying judgment can improve the accuracy of quality assessment. And first determine the benchmark score, and then consider the impact of the retransmission rate on the score to obtain the final quality score, which can further improve the accuracy of the quality evaluation.

And in this embodiment, in the uplink quality evaluation process, in the case of a large uplink transmission delay, the uplink evaluation is further carried out according to the downlink transmission rate, so as to avoid direct evaluation in the case of a large delay. Poor quality, which improves the accuracy of quality assessment. In addition, in the process of downlink quality evaluation, the uplink transmission delay is used for evaluation, so as to avoid using inaccurate downlink transmission delay for quality evaluation, which can improve the accuracy of quality evaluation.

In a possible case, the transmission parameter acquired by the terminal device indicates that there is no data packet transmission within the current sampling period, and in this case, no quality evaluation will be performed. Exemplary embodiments will be described below.

Please refer to FIG. 6 , which shows a flowchart of a method for determining network quality provided by another exemplary embodiment of the present application. This embodiment is described by taking the method being executed by a terminal device as an example. The method includes the following steps:

Step 601: Obtain uplink transmission parameters for data packet transmission in the uplink and downlink transmission parameters for data packet transmission in the downlink.

Optionally, the terminal device is provided with a network control module, a TCP scoring processing module, a TCP scoring control module, and a TCP statistics scoring module. Among them, the network control module is used to control the network quality, which can adjust the network to change the network quality. The TCP score processing module can interact with the network control module, and can determine the network quality according to the uplink quality score and the downlink quality score obtained by the evaluation. The TCP control module is used to control whether to enable or disable the TCP scoring function. The TCP statistical scoring module is used to determine the uplink quality score and the downlink quality score according to the transmission parameters.

In a possible implementation manner, when the TCP statistics scoring module receives the scoring opening notification sent by the TCP scoring control module, it acquires the uplink transmission parameters and the downlink transmission parameters every target period.

Step 602, in the case that the uplink transmission parameter indicates that there is no data packet transmission in the uplink, determine the uplink quality score as the historical uplink quality score.

In a possible implementation, when the uplink transmission rate in the uplink transmission parameter is 0, that is, when the number of uplink packets per second is 0, it is determined that there is no data packet transmission in the current uplink. At this time, the TCP The statistical scoring module does not perform uplink quality evaluation, but determines the historical uplink quality score determined in the previous cycle as the uplink quality score.

As shown in FIG. 4 , in the case that the number of uplink packets per second = 0, the historical uplink quality score is maintained.

If there is data packet transmission, the TCP statistics scoring module determines the upstream quality score according to the upstream scoring method and stores it.

Step 603, in the case that the downlink transmission parameter indicates that there is no data packet transmission in the downlink, determine the downlink quality score as the historical downlink quality score.

Correspondingly, when the downlink transmission rate is 0, that is, the number of downlink packets per second is 0, it is determined that there is no data packet transmission in the current downlink. The downlink quality score is determined as the downlink quality score.

As shown in FIG. 5 , in the case that the number of downlink packets per second = 0, the historical downlink quality score is maintained.

If there is data packet transmission, the TCP statistical scoring module determines the downstream quality score according to the downstream scoring method and stores it.

Step 604: Determine the network quality based on the uplink quality score and the downlink quality score.

After the TCP statistic and scoring module determines the uplink quality score and the downlink quality score, it will report the score to the TCP score control module. The TCP score control module forwards the score to the TCP score processing module. Quality Score, which determines network quality.

Step 605 , in the case that the network quality changes, the network adjustment policy is invoked, and the network adjustment policy is used to adjust the network quality.

In a possible implementation, when the TCP scoring processing module determines that the network quality has changed compared with the historical network quality, the current network quality is reported to the network control module, and the network control module invokes the network adjustment strategy, according to the change of the network quality. Adjust the network quality according to the situation. For example, when the network control module determines that the network quality is deteriorated, the current network can be adjusted.

Optionally, when the TCP score processing module determines that the score has changed compared to the score of the previous cycle, the network quality is reported. Or, in another possible implementation, in order to avoid frequent reporting, when the network quality level changes compared to the network quality level of the previous cycle, the network quality is reported again, so that the network control module invokes the network adjustment policy.

As shown in Figure 7, it shows a schematic diagram of the architecture of quality scoring. When the network control module 701 needs to evaluate the network quality, it will register the network quality evaluation policy. After receiving the registration information, the TCP scoring processing module 702 performs a TCP scoring subscription, that is, notifies the TCP scoring control module 703 to enable the TCP scoring function, and the TCP scoring The control module 703 sends a TCP score start notification to the TCP statistics scoring module 704. After the TCP statistics scoring module 704 determines the uplink quality score and the downlink quality score, it will report the TCP score. After receiving the reported score, the TCP score control module 703 will The score is notified to the TCP score processing module 702, and the TCP score processing module 702 determines the network quality according to the score, and reports the network quality to the network control module 701 when the network quality changes. The network control module 701 invokes a network adjustment policy to adjust the network quality according to the change of the network quality.

In this embodiment, after it is determined that the network quality changes, the network quality can be adjusted according to the change of the network quality in time, so as to maintain a good network quality and help ensure the smoothness of service use.
