Detailed Description
To make the objects, technical solutions and advantages of the present application more clear, the following detailed description of the embodiments of the present application will be made with reference to the accompanying drawings.
Fig. 1 is a schematic diagram illustrating an implementation environment provided by an exemplary embodiment of the present application, which may include: terminal device 110 and server 120. Data communication is performed between the terminal device 110 and the server 120 through a communication network, which may be at least one of a local area network, a metropolitan area network, and a wide area network, and may optionally be a wired network or a wireless network.
The terminal device 110 may include various handheld devices, vehicle-mounted devices, wearable devices, computer devices or other processing devices connected to a wireless modem with data transmission functions, as well as various forms of user equipment, Mobile Stations (MSs), terminal devices (terminal devices), and so on.
The server 120 may be an independent physical server, or may be a server cluster or a distributed system formed by a plurality of physical servers. Server 120 may forward data from other devices to terminal device 110. Terminal device 110 may be capable of bi-directional transmission of data with server 120.
In a possible implementation manner, the method for determining network quality provided by this embodiment may be applied to the terminal device 110 shown in fig. 1, where the terminal device 110 may obtain an uplink transmission parameter in a process of sending data to the server 120 by the terminal device 110, and obtain a downlink transmission parameter in a process of receiving data sent by the server 120 by the terminal device 110, so that the terminal device 110 may determine an uplink quality score and a downlink quality score of an uplink according to the uplink transmission parameter and the downlink transmission parameter, and perform network quality evaluation based on the uplink quality score and the downlink quality score.
Referring to fig. 2, a flowchart of a method for determining network quality according to an exemplary embodiment of the present application is shown, where this embodiment is described as an example implemented by a terminal device, and the method includes the following steps:
step 201, an uplink transmission parameter for data packet transmission in an uplink and a downlink transmission parameter for data packet transmission in a downlink are obtained.
The uplink refers to a channel through which the terminal device transmits data, and the downlink refers to a channel through which the terminal device receives data.
In the embodiment of the application, the terminal device obtains the uplink transmission parameter when transmitting data in the uplink and the downlink transmission parameter when transmitting data in the downlink, so as to evaluate the network quality according to the uplink transmission parameter and the downlink transmission parameter.
In a possible implementation manner, the terminal device obtains the uplink transmission parameter and the downlink transmission parameter in the process of using the data service by the user, and evaluates the network quality in time, so as to adjust the network according to the evaluated network quality, and avoid the influence of poor network quality on the data service. Optionally, the terminal device may perform sampling with the target duration as a period, that is, obtain the uplink transmission parameter and the downlink transmission parameter within the target duration. Illustratively, the target duration may be 1s, and the terminal device may obtain the uplink transmission parameter and the downlink transmission parameter within the history 1s in a period of 1s, to perform the evaluation of the network quality.
In one possible embodiment, the terminal device evaluates the quality of the uplink and the quality of the downlink, respectively. The uplink corresponds to an uplink scoring mode, which is a mode for indicating that the uplink quality is evaluated by using the transmission parameters. When the transmission parameters are acquired, the terminal equipment can determine the uplink quality score corresponding to the uplink according to the uplink scoring mode.
Since the transmission of the downlink may affect the transmission of the uplink in the transmission process of the uplink, and the uplink quality score is determined only based on the uplink transmission parameter of the uplink, the quality of the uplink cannot be accurately evaluated, so that the terminal device determines the uplink quality score by using the uplink transmission parameter and the downlink transmission parameter together.
Accordingly, the downlink scoring mode is used to indicate a mode of evaluating downlink quality using the transmission parameters. When the transmission parameters are acquired, the terminal device can determine the downlink quality score corresponding to the downlink according to the downlink scoring mode.
And in the downlink quality evaluation process, the downlink quality score is determined based on the uplink transmission parameters and the downlink transmission parameters, so that the accuracy of the downlink quality score is ensured.
And step 204, determining 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 perform the evaluation of the network quality.
In the process of determining the uplink quality score and the downlink quality score, the uplink transmission parameter and the downlink transmission parameter are determined together, so that the condition that network quality evaluation is inaccurate due to the influence of a data interaction process between an uplink and a downlink on transmission can be avoided, the accuracy of evaluating the uplink quality and the downlink quality is improved, and the accuracy of determining the network quality can be improved by evaluating the current network quality by the terminal equipment based on the uplink quality and the downlink quality.
To sum up, in the embodiment of the present application, the terminal device uses the uplink transmission parameter of the uplink and the downlink transmission parameter of the downlink to respectively evaluate the quality of the uplink and the quality of the downlink, so as to obtain an uplink quality score and a downlink quality score, and thus determine the final network quality according to the uplink quality score and the downlink quality score. Because the uplink and downlink parameters are jointly evaluated in the process of evaluating the quality of the uplink and the downlink, the accuracy of evaluating the actual data transmission quality of the uplink and the downlink can be improved, and the accuracy of determining the network quality is improved.
Optionally, the terminal device evaluates the uplink quality according to the uplink scoring mode, and evaluates the downlink quality according to the downlink scoring mode. The following embodiments will schematically describe an uplink scoring manner and a downlink scoring manner.
Referring to fig. 3, a flow chart of a method for determining network quality provided by another exemplary embodiment of the present application is shown. The embodiment is described by taking an example in which the method is executed by a terminal device. The method comprises the following steps:
step 301, obtaining uplink transmission parameters for data packet transmission in uplink and downlink transmission parameters for data packet transmission in downlink.
In the data Transmission process, Transmission is generally performed using a Transmission Control Protocol (TCP). In a possible implementation manner, the uplink transmission parameter and the downlink transmission parameter are transmission parameters in the process of transmitting the TCP data packet.
In the process of acquiring the uplink transmission parameters and the downlink transmission parameters, the terminal equipment can acquire the uplink transmission rate, the uplink retransmission rate and the uplink transmission delay of the TCP data packet on an uplink; correspondingly, the terminal equipment can obtain the downlink transmission rate, the downlink retransmission rate and the downlink transmission delay of the TCP data packet in the downlink. Wherein, the transmission rate is the number of data packets transmitted per second in the link; the retransmission rate is the number of normal TCP packets transmitted in the link/(the number of normal TCP packets + the number of retransmitted TCP packets); the transmission delay is the average Round Trip Time (RTT) of the TCP packet.
Step 302, determining an uplink quality score based on the uplink transmission parameter when the uplink transmission rate in the uplink transmission parameter is greater than the first rate threshold.
In the process of scoring according to the uplink scoring mode, the terminal device will first evaluate the uplink quality with the uplink transmission rate as a reference. Optionally, the uplink transmission parameter includes an uplink transmission rate of the TCP packet, and when the uplink transmission rate is higher, it indicates that the uplink quality is better, and the uplink quality score may be determined only by using the uplink transmission parameter without referring to other transmission parameters. In one possible implementation, this step may include steps 302a-302 b:
step 302a, under the condition that the uplink transmission rate is greater than the first rate threshold value, determining the uplink benchmark score of the uplink as the highest score.
In the case where 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 better, and therefore, the uplink reference score of the uplink may be determined to be the highest score. The first rate threshold is a preset value, for example, the first rate threshold is 240 packets per second. In one possible embodiment, the first rate threshold may be further determined by using the influence of the transmission rate, i.e. the bandwidth, i.e. the first rate threshold is the product of the threshold and the bandwidth impact factor. Illustratively, the first rate threshold is 240 bandwidth impact factor. The bandwidth influence factor represents a weight ratio of the influence of the transmission rate on the quality, and may be, for example, 1.2.
Illustratively, as shown in fig. 4, the number of uplink packets per second is the uplink transmission rate, and when the number of uplink packets per second is greater than 240 × bandwidth impact factor, it is determined as a high-rate scenario, and the uplink benchmark score is 100.
And step 302b, determining an uplink quality score based on the uplink reference score and the uplink retransmission rate in the uplink transmission rate.
Since there may be a case where transmission of a data packet fails during transmission of a TCP data packet, in this case, retransmission of the TCP data packet is performed, and when a retransmission rate of the TCP data packet is high, it indicates that network quality is poor, and therefore, when quality evaluation is performed, the TCP retransmission rate needs to be considered. In a possible embodiment, the terminal device is pre-provisioned with a retransmission rate impact factor, which represents an impact weight on the quality evaluation. Illustratively, the retransmission rate impact factor may be 0.8. After the retransmission rate is obtained, the retransmission rate influence score can be determined based on the product of the reference score and the retransmission rate influence factor, so that the final quality score can be determined according to the reference score and the retransmission rate influence score.
Namely, the uplink quality score-uplink reference score-uplink retransmission rate-retransmission rate influence factor. Schematically, as shown in fig. 4, in the case that the number of uplink packets per second is greater than 240 × bandwidth impact factor, the uplink quality score is 100-.
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, the uplink quality needs to be further evaluated based on other transmission parameters. Optionally, in the case that the uplink transmission rate is less than the first rate threshold, performing quality evaluation according to other transmission parameters may include the following cases:
under the condition that the uplink transmission delay in the uplink transmission parameters is smaller than a first delay threshold or larger than a second delay threshold, determining an uplink reference score of an uplink based on the uplink transmission delay, wherein the uplink transmission delay and the uplink reference score are in a negative correlation relationship.
And when the uplink transmission rate is smaller than the first rate threshold, the terminal equipment further evaluates the quality according to the uplink transmission delay. The first delay threshold may be a preset threshold. Illustratively, the first latency threshold may be 400 ms. When the uplink transmission delay is smaller than the first delay threshold, it indicates that the transmission delay is smaller, and the uplink reference score may be determined based on the uplink transmission delay only, where the uplink reference score is higher when the uplink transmission delay is smaller.
Further, the transmission delay may be divided into intervals when the uplink transmission delay is smaller than the first delay threshold. And under the condition that the uplink transmission delay is smaller than a fourth delay threshold value, determining that the uplink reference score is the first grade score, namely the highest score. Illustratively, the fourth delay threshold is 200ms, and the uplink benchmark score is determined to be 100 when the uplink transmission delay is less than 200 ms. And under the condition that the uplink transmission time delay is greater than the fourth time delay threshold and less than the fifth time delay threshold, determining that the uplink benchmark score is a second grade score which is lower than the first grade score. Wherein the fourth delay threshold is less than the fifth delay threshold, and the fifth delay threshold is less 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. And when the uplink transmission delay is greater than the fifth delay threshold and smaller than the first delay threshold, determining that the uplink standard score is a third grade score which is smaller than the second grade score. Illustratively, in the case that 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, the determination delay is too large, which indicates that the network quality is poor, so that the uplink reference score can be directly determined based on the uplink transmission delay. And under the condition that the uplink transmission time delay is greater than the second time delay threshold value, the terminal equipment determines that the uplink reference score is a fourth grade score, namely a lowest score. Illustratively, the second latency threshold may be 1000ms, and when the uplink transmission latency is greater than 1000ms, the uplink benchmark score is determined to be 59.
And secondly, under the condition that the uplink transmission delay is larger than the first delay threshold and smaller than the second delay threshold, determining an uplink reference score based on the downlink transmission rate in the downlink transmission parameters, wherein the downlink transmission rate and the uplink reference score are in positive correlation.
And indicating that the transmission delay is larger under the condition that the uplink transmission delay is larger than the first delay threshold and smaller than the second delay threshold. In this case, on one hand, the delay may be large due to network reasons, and on the other hand, the transmission delay is RTT of the TCP packet, where RTT is time when the data packet is sent to an Acknowledgement Character (ACK). The ACK data is sent from the receiving end device to the terminal device. When there are more data packets transmitted in the downlink, the ACK data transmission is slower, and correspondingly, the RTT is larger. Therefore, when the number of data packets transmitted in the downlink is large, the uplink transmission delay may be large, which is not the reason of 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 further needs to continue to perform uplink quality evaluation with reference to the downlink transmission delay, that is, the number of data packets transmitted per second in the downlink, to determine whether the uplink transmission delay caused by the network is large. Wherein, the downlink transmission rate and the uplink reference score are in positive correlation. Under the condition that the downlink transmission rate is higher, the larger the number of the transmitted data packets in the downlink is, the larger the transmission delay possibly caused by network reasons is, and the higher the uplink reference score corresponding to the corresponding uplink is.
Optionally, when the downlink transmission rate is greater than the third rate threshold, the uplink benchmark score is determined to be the first-level score. The third rate threshold is greater than the first rate threshold, for example, the number of the third rate threshold is 400 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-level 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, when the downlink transmission rate is less than the first rate threshold, the uplink benchmark score is determined to be a fourth-level 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 one possible implementation, the uplink quality score is determined based on the uplink reference score and the uplink retransmission rate in the uplink transmission parameter.
And when the uplink transmission rate is smaller than the first rate threshold, the terminal equipment determines to obtain an uplink reference score according to the uplink transmission delay and the downlink transmission rate, and then determines a final uplink quality score based on the uplink retransmission rate. This method can refer to the step 302b, and is not described herein again.
Schematically, as shown in fig. 4, under the condition that the uplink transmission rate, i.e., the number of uplink packets per second, is less than or equal to 240 × bandwidth impact factor, the secondary determination is performed based on the uplink transmission delay, i.e., the uplink RTT. Determining an uplink quality score as 100-; determining an uplink quality score as 80-80 retransmission rate influence factor under the condition that uplink RTT is more than 200ms and less than 300 ms; determining an uplink quality score as 70-70 retransmission rate influence factor under the condition that the uplink RTT is more than 300ms and less than 400 ms; in case of uplink RTT > 1000ms, the uplink quality score is determined to be 59-59 retransmission rate impact factor. And under the condition that the uplink RTT is more than 400ms and less than 1000ms, the judgment is further carried out according to the downlink transmission rate, namely the number of downlink packets per second. When the number of downlink packets per second is more than 400, determining the uplink quality score as 100 + retransmission rate influence factor; determining the uplink quality score as 80-80 retransmission rate influence factor under the condition that the downlink packet number per second is more than 240 and less than 400; in case of downlink packet number per second < 240, the uplink quality score is determined to be 59-59 retransmission rate impact factor.
In a case where the uplink transmission rate is less than the first rate threshold, there may be a case where the uplink transmission rate is small, in which case, further acquiring other transmission parameters for quality evaluation, in which case, determining the uplink quality score may include the following steps:
step one, under the condition that the uplink transmission rate and the downlink transmission rate in the downlink transmission parameters are smaller than a second rate threshold, and the uplink transmission delay in the uplink transmission parameters is larger than a third delay threshold, determining that the uplink reference score of the uplink is the lowest score, wherein the second rate threshold is smaller than the first rate threshold.
In a possible embodiment, the number of data packets transmitted in the uplink is determined to be less in case the uplink transmission rate is smaller than the second rate threshold. Thus, the second rate threshold is much lower than the first rate threshold, which may be 10 packets per second. When the uplink transmission rate is determined to be smaller than the second rate threshold, the downlink transmission rate needs to be further determined, and when the downlink transmission rate is also smaller than the second rate threshold, the current data packet number is less to transmit, and more data packets do not need to be transmitted in the current service scene, for example, a game service scene. In this scenario, the transmission delay is usually low, for example, around 100 ms. If the transmission delay is higher, the network quality is poor, and therefore after the uplink transmission rate and the downlink transmission rate are determined to be smaller than the second rate threshold, the uplink reference score is further determined according to the uplink transmission delay. And under the condition that the uplink transmission delay is greater than a third delay threshold value, determining that the current transmission rate is low, and the uplink benchmark score is a fourth grade score, namely a lowest score. For example, the third delay threshold is 170 ms.
And step two, determining an uplink quality score based on the uplink reference score and the uplink retransmission rate in the uplink transmission parameters.
And after the uplink reference score is obtained, determining the uplink quality score by using the uplink retransmission rate. The above steps can be referred to in this manner, and are not described herein again.
Illustratively, as shown in fig. 4, in the case where the number of uplink packets per second < 10& & the number of downlink packets per second < 10& & the uplink RTT > 170ms, the uplink quality score is determined to be 59-59 &retransmissionrate influence factor.
And 304, determining a downlink quality score based on the downlink transmission parameters under the condition that the downlink transmission rate in the downlink transmission parameters is greater than a first rate threshold.
The above steps are exemplary for the uplink scoring method. The downlink scoring method will be described in the following. The same way as the uplink scoring is that the terminal device first performs downlink quality evaluation with the downlink transmission rate as a reference. Under the condition that the acquired downlink transmission rate is greater than the first rate threshold, the terminal equipment determines that the downlink transmission rate is a high-rate scene and the downlink quality is good, so that the downlink reference score of the downlink can be determined to be the highest score.
And after determining the downlink reference score, further determining to obtain a downlink quality score according to the downlink retransmission rate. Downlink quality score-downlink reference score-downlink retransmission rate-retransmission rate impact factor.
Illustratively, as shown in fig. 5, in the case that the number of downlink packets per second is greater than 240 × bandwidth impact factor, it is determined as a high rate scenario, the downlink reference score is 100, and the downlink quality score is 100-.
And when the downlink transmission rate is smaller than the first rate threshold, determining that the scene is a low rate scene, and the terminal device needs to further determine a downlink quality score by using the uplink transmission parameters and the downlink transmission parameters. The method can comprise the following steps:
and 305a, determining a downlink reference score of the downlink based on the uplink transmission delay in the uplink transmission parameters, wherein the uplink transmission delay and the downlink reference score are in a negative correlation relationship.
And under the condition that the downlink transmission rate is smaller than the first rate threshold, further judging according to the transmission delay. However, during the data transmission process of the downlink, the terminal device is a receiving end, and cannot confirm the actual sending time, that is, cannot determine the accurate downlink transmission delay (downlink RTT), so in a possible embodiment, in the case that the downlink transmission rate is smaller than the first rate threshold, the terminal device further performs the quality evaluation of the downlink according to the uplink transmission delay. The larger the uplink transmission delay, the lower the downlink reference score.
Optionally, when the uplink transmission delay is greater than the first delay threshold, determining that the downlink reference score is a fourth-level score; and under the condition that the uplink transmission time delay is smaller than a first time delay threshold value, determining the downlink benchmark score as a first grade score.
And 305b, determining a downlink quality score based on the downlink reference score and the downlink retransmission rate in the downlink transmission parameters.
And after determining the downlink reference score, further determining a downlink quality score according to the downlink retransmission rate.
Schematically, as shown in fig. 5, under the condition that the number of downlink packets per second is less than or equal to 240 × bandwidth influence factor, if the uplink RTT is greater than 400ms, determining that the downlink quality score is 59-59 × retransmission rate influence factor; if the uplink RTT is less than or equal to 400ms, the uplink quality score is determined to be 100 + 100 retransmission rate influence factor (not shown in the figure).
In the data transmission process, a packet loss condition exists, when the packet loss condition occurs, retransmission of a data packet is required, transmission delay is increased, and in another possible implementation mode, quality evaluation can be further performed according to the number of the lost packets. In this way, the downlink quality score is-2 × number of packets lost × RTT/1000.
As shown in fig. 5, when the uplink RTT is less than or equal to 400ms, the downlink quality score is 100-2 packet loss RTT/1000.
And step 306, determining the quality grade of the network quality based on the lowest grade of the uplink quality grade and the downlink quality grade.
After the uplink quality score and the downlink quality score are obtained, the network quality grade can be determined according to the lowest score in the uplink quality score and the downlink quality score. The terminal device stores corresponding relations between different grades and quality grades in advance, and after the lowest grade is determined, the quality grade corresponding to the lowest grade can be determined as the quality grade of the current network quality.
Illustratively, the corresponding relationship between the score and the quality grade is shown in table 1:
TABLE 1
| Scoring | Quality grade |
| 80-100 | Superior food |
| 60-80 | Medium and high grade |
| 40-60 | Is poor |
| ＜40 | Difference (D) |
With reference to the example in table 1, when the uplink quality score is determined to be 90 and the downlink quality score is 70, the quality grade of the network quality is determined according to the downlink quality score 70, and the quality grade is medium.
In this embodiment, the link quality is evaluated based on the transmission rate, and when the transmission rate is high, evaluation based on other parameters is not required, and when the transmission rate is low, determination is further performed based on the transmission delay, so that accuracy of quality evaluation can be improved. And firstly, determining a reference score, and then considering the influence of the retransmission rate on the score to obtain a final quality score, so that the accuracy of quality evaluation can be further improved.
In addition, in the embodiment, in the uplink quality evaluation process, under the condition of a large uplink transmission delay, the uplink is further evaluated according to the downlink transmission rate, so that the situation that the quality is directly evaluated to be poor under the condition of a large delay is avoided, and the accuracy of quality evaluation can be improved. In the downlink quality evaluation process, the uplink transmission delay is adopted for evaluation, so that inaccurate downlink transmission delay is avoided for quality evaluation, and the accuracy of quality evaluation can be improved.
In a possible case where the transmission parameter obtained by the terminal device indicates that there is no data packet transmission during the current sampling period, no quality assessment will be performed. The following description will be made with reference to exemplary embodiments.
Referring to fig. 6, a flow chart of a method for determining network quality provided by another exemplary embodiment of the present application is shown. The present embodiment is described by taking an example in which the method is executed by a terminal device. The method comprises the following steps:
step 601, obtaining an uplink transmission parameter for data packet transmission in an uplink and a downlink transmission parameter for data packet transmission in a 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 statistical scoring module. The network control module is used for controlling the network quality and can adjust the network so as to change the network quality. The TCP scoring 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 evaluation. The TCP control module is used for controlling whether to enable or close the TCP scoring function. And the TCP statistical scoring module is used for determining an uplink quality score and a downlink quality score according to the transmission parameters.
In a possible implementation manner, when the TCP statistics scoring module receives a scoring start notification sent by the TCP scoring control module, the uplink transmission parameters and the downlink transmission parameters are acquired at intervals of a target period.
In a possible embodiment, in the case that the uplink transmission rate in the uplink transmission parameter is 0, that is, the number of uplink packets per second is 0, it is determined that there is no data packet transmission in the current uplink, and at this time, the TCP statistical scoring module does not perform quality evaluation of the uplink, and determines the historical uplink quality score determined in the previous period as the uplink quality score.
As shown in fig. 4, in the case where the number of uplink packets per second is 0, the historical uplink quality score is maintained.
And if the data packet transmission exists, the TCP statistic scoring module determines the uplink quality score according to an uplink scoring mode and stores the uplink 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, and at this time, the TCP statistical scoring module determines the historical downlink quality score determined in the previous period as the downlink quality score.
As shown in fig. 5, in the case where the number of downlink packets per second is 0, the historical downlink quality score is maintained.
And if the data packet transmission exists, the TCP statistic scoring module determines the downlink quality score according to a downlink scoring mode and stores the downlink quality score.
And step 604, determining the network quality based on the uplink quality score and the downlink quality score.
And when the TCP statistic scoring module determines the uplink quality score and the downlink quality score, the scores are reported to the TCP scoring control module, the TCP scoring control module forwards the scores to the TCP scoring processing module, and the TCP scoring processing module determines the network quality according to the uplink quality score and the downlink quality score.
In a possible implementation manner, after the TCP scoring processing module determines that the network quality changes compared with the historical network quality, the current network quality is reported to the network control module, and the network control module invokes a network adjustment policy to adjust the network quality according to the change condition of the network quality. For example, when the network control module determines that the network quality is degraded, adjustments may be made to the current network.
Optionally, when the TCP score processing module determines that the score changes compared with the score in the previous cycle, the TCP score processing module reports the network quality. Or, in another possible implementation manner, 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, so that the network control module invokes a network adjustment policy.
As shown in fig. 7, an architectural diagram of quality scoring is shown. When the network control module 701 needs to evaluate the network quality, a network quality evaluation strategy is registered, the TCP scoring processing module 702 receives registration information and then performs TCP scoring subscription, that is, the TCP scoring control module 703 starts a TCP scoring function, the TCP scoring control module 703 sends a TCP scoring start notification to the TCP statistical scoring module 704, after the TCP statistical scoring module 704 determines an uplink quality score and a downlink quality score, the TCP scoring module reports the TCP score, after the TCP scoring control module 703 receives the reported score, the TCP scoring processing module 702 is notified of the score, the TCP scoring processing module 702 determines the network quality according to the score, and when the network quality changes, the network control module 701 reports the network quality. The network control module 701 invokes a network adjustment policy to adjust the network quality according to the network quality change condition.
In the embodiment, after the network quality is determined to change, the network quality can be adjusted in time according to the change condition of the network quality, so that good network quality is kept, and the smoothness of service use is favorably ensured.
