【Technical field】

The present application relates to the field of communication technologies, and in particular, to a method and device for detecting interruption of network data, a terminal device, and a storage medium.

【Background technique】

In the process of real-time data transmission, data interruption often occurs due to network instability. Therefore, it is necessary to judge the occurrence of data interruption in time, and perform interruption recovery in time to ensure the normal progress of network data transmission.

In the prior art, the judgment of flow interruption is realized by periodically detecting the number of packets in the transmission process, which specifically includes the following steps: detecting whether the number of packets received in a single cycle is greater than 0; if the number of packets received is greater than 0; If it is greater than 0, it will enter the next cycle of detection; if the number of packets received in the current cycle is 0, and the number of sent packets is less than the threshold, the number of packets received in the current cycle will be accumulated to enter the next cycle If the number of packets received in the current cycle is 0, and the number of packets sent is greater than the threshold, it will be judged as a cut-off state, and the cut-off recovery process will be started.

Due to the variability of the network, some data interruptions occur gradually. In the existing flow interruption judgment process, only the number of packets is used for judgment, and it is impossible to judge the state of entering the flow interruption. In the next cycle, the number of received packets is 0, and the number of sent packets exceeds the threshold. , the data interruption will often be restored. Before the data flow is completely cut off, the network data transmission efficiency is poor and cannot be effectively improved when the data transmission is delayed or blocked.

【detailed description】

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of this application. In the case of no conflict, the following various embodiments and their technical features can be combined with each other.

Please refer to FIG. 1 , which is a schematic flowchart of a method for detecting interruption of network data flow according to an embodiment of the present invention.

In this embodiment, the network data interruption detection method includes the following steps:

Step S101: Count the packet traffic in a detection period, and record the round-trip delay of each packet.

The round-trip delay (RTT, Round Trip Time) of the arrival packet is the round-trip delay time of the packet, which specifically represents the total elapsed time from when the sender sends data to when the sender receives the acknowledgment from the receiver. form of transmission.

In the process of data transmission, "outgoing packets" are continuously sent out and "arrival packets" are received. In one detection period, the numbers of outgoing packets and arriving packets are counted, so as to obtain the packet flow, where the packet flow is the difference between the number of outgoing packets and the number of arriving packets.

While the packet traffic is counted, the RTT of each packet is also recorded. In some embodiments, the TRR of the sent packet can be calculated according to the sending time of the sent packet and the time of receiving the acknowledgement from the receiving end; the RTT of the arriving packet can be calculated according to the sending time in the arriving packet and the current time when the packet is received .

When the device is in use, such as when the screen of the mobile phone is on, the statistical time in the detection cycle is short, so that the data interruption state can be detected in time; while when the device is in the standby state, such as when the screen of the mobile phone is black, the statistical time in the detection cycle is short. The statistical time can be longer to reduce power consumption.

In one embodiment, the statistical time T1=1min of the detection period in the device use state, and every 1 minute, the packet traffic and RTT within the 1 minute are detected; the statistical time of the detection period in the standby state is T2=6min, every 1 minute Every 6 minutes, check the packet traffic and RTT within these 6 minutes. In other embodiments, settings may be made according to specific conditions.

Step S102: Determine whether the packet flow in the current detection period is greater than or equal to a first threshold.

The first threshold may be set according to a statistical average value of packet traffic during multiple data interruptions, and according to a requirement for detection accuracy of data interruptions. In some embodiments, the first threshold may range from 0 to 15.

If not, step S103 is performed: the number of outgoing packets and the number of arriving packets are cleared, and the process returns to step S101 to enter the next detection cycle. When the packet flow is less than the first threshold, it indicates that the difference between the number of received packets and the number of sent packets is small, the data transmission is relatively smooth, and there is no data interruption in the current detection cycle, so the next cycle of detection is directly entered. Process.

If the packet flow in the current detection period is greater than or equal to the first threshold, it indicates that the number of outgoing packets and the number of arriving packets are quite different, the smoothness of data transmission in the current period is low, there is data packet loss, and data flow may be about to be interrupted , data interruption or data congestion and other situations have occurred, and further judgment is required, so step S104 is performed: compare the average round-trip delay of all packets with the second threshold, and determine whether the average delay is greater than or equal to the second threshold. .

In some embodiments, the second threshold may be obtained by calculating the average value of RTT statistics when data is cut off for multiple times. This method is more suitable for environments with relatively stable network parameters.

Further, since RTT is related to network environment parameters, such as network parameters such as bandwidth, router parameters, transmission frequency band, etc., and in the process of network communication, the network parameters may change frequently, and the second threshold needs to be dynamically adjusted following the changes of the environment parameters. In some embodiments, the network parameters and the average value of the round-trip delays of several packets before and after the data interruption are recorded every time the data is interrupted; thus, the corresponding relationship between the network parameters and the average value of the RTT can be obtained when the data is interrupted. , thereby forming each preset second threshold corresponding to each network parameter. The preset second threshold may directly use the average value of the RTT, or may add a certain offset on the basis of the average value of the RTT. In the subsequent detection process of data interruption, the corresponding preset second threshold can be selected according to the current network parameters as the second threshold of the current detection period; when the network parameters change, the second threshold also changes accordingly .

In step S104, if the average round-trip delay is greater than or equal to the second threshold, it is determined that the current data transmission state is a data cutoff state. When the packet traffic is greater than or equal to the first threshold, and the average round-trip delay is greater than or equal to the second threshold, it means that during the data transmission process, the amount of data sent is greater than the amount of received data, and the network delay is large, so effective data transmission cannot be performed. During the detection period, the network is in a data cutoff state.

After the data current interruption state is detected, step S105 is performed: the current interruption recovery process is started. The current interruption recovery process may include, but is not limited to, restarting the device, re-establishing a network path, switching signal frequency bands, etc. Those skilled in the art may adopt an appropriate current interruption recovery process, which will not be repeated here. After the completion of step S105 and the data interruption is recovered, continue to return to step S101 to re-enter the data interruption detection of the next detection cycle and the statistical time of the next cycle is set to the initial value.

In step S104, if the average round-trip delay is less than the second threshold, step S106 is performed: the number of outgoing packets and the number of arriving packets are accumulated to the next detection period, and step S101 is performed to enter the next detection period. At this time, within the statistical time of the next detection period, on the basis of the number of outgoing packets and the number of arriving packets in the previous detection period, according to the new number of outgoing packets and the new number of arriving packets, and calculate the packet flow, and The average RTT of newly added packets during the period.

For example, the number of outgoing packets in the last detection cycle is a1, the number of arriving packets is b1, the number of outgoing packets corresponding to the current detection cycle is a2, and the number of arriving packets is b2, where a2 is the new number of outgoing packets in the current detection cycle , b2 is the number of newly arrived packets in the current detection period, and the packet flow is: a2-b1.

In the above embodiment, whether the data flow is interrupted is detected from the perspective of the difference in the number of packets and the transmission delay through the average value of the packet flow and the RTT, which can improve the accuracy of the data flow interruption and detect the data flow interruption in time.

Please refer to FIG. 2 , which is a schematic flowchart of a method for detecting interruption of network data flow according to an embodiment of the present invention.

In step S104, when the packet traffic is less than the first threshold and the average RTT value is less than the second threshold, although the data flow has not been interrupted, the data transmission is not smooth. Congestion and other situations that are prone to interruptions in time.

In order to detect the occurrence of data interruption in time, in this embodiment, on the basis of the network data interruption detection process shown in FIG. 1, after step S106, step S201 is added: shortening the statistics of the next detection period time. Shortening the statistical time can increase the number of detections and judgments within the same time period, quickly refresh the average value of packet traffic and TRR, and make judgments. Once data interruption occurs, it can be detected immediately, thereby shortening the time it takes to detect data interruption. . In other embodiments, the sequence of the step S201 and the step S106 may be exchanged or performed simultaneously, and there is no strict sequence requirement for the step S201 and the step S106.

If in the detection period after the statistical time is shortened, the average RTT value is still smaller than the second threshold, before entering the next detection period, the statistical time of the next detection period is shortened again. Since the current interruption is about to occur, the later the detection time is, the shorter the detection time of each detection cycle is, the faster the detection data can be updated, and the detection time can be shortened. When the average RTT value is greater than or equal to the second threshold within a certain detection period, the data interruption state is detected, and the process proceeds to step S105; or the packet flow rate is less than the threshold value, and the data transmission returns to normal (for example, a short-term congestion relief), the detection period is resumed the statistical time to the initial value.

In some embodiments, the ratio of shortening the statistical time is the same each time, which may be in the range of 30% to 60%, preferably, it may be 50%. For example, the initial value of the detection period is T1=1min in the use state and T2=6min in the standby state; after the first shortening, T1=30s, T2=180s; in the first shortened detection period, at this time The statistical time is T1=30s or T2=180s. If the packet traffic is greater than the first threshold again and the average RTT value is less than the second threshold, the statistical time of the next cycle is reduced a second time by 50% and becomes T1 =15s, T2=90s; if the packet traffic is greater than the first threshold and the average RTT is less than the second threshold again in the subsequent statistical time, the statistical time will be reduced again until the packet traffic is greater than the first threshold and the average RTT If the value is greater than or equal to the second threshold, enter step S105: start the flow cut recovery process, or detect that the packet flow is less than the first threshold, restore the statistical time in the next detection cycle to the initial value, in the use state T1=1min, in the standby state Lower T2=6min.

In other embodiments, the ratio of shortening the statistical time can also be increased successively, for example, the first time shortens by 30%, the second time shortens by 50%, the third time shortens by 60%, and so on.

Please refer to FIG. 3 , which is a schematic flowchart of a data interruption detection process according to another embodiment of the present invention.

In this embodiment, on the basis of the network data interruption detection process shown in FIG. 2, after shortening the statistical time of the next detection period in step S201, the method further includes:

Step S301: count the number of times that the statistical time is continuously shortened;

Step S302: determine whether the count reaches the set value, if not, continue to perform the detection of the next detection cycle; if so, determine that the current data transmission state is the data cutoff state, and execute step S105: start the cutoff recovery process.

The set value may be an integer greater than 2, and preferably, the set value may be 3, that is, after the statistical time is shortened three times in a row, the current interruption recovery process is started.

Usually, the packet traffic caused by network congestion is larger than the threshold, and it will be eliminated in a short time. However, if the packet traffic is larger than the threshold for many times in a row, it will not be eliminated in a short time, even if the average RTT is still less than the second threshold. The real data cutoff is achieved, but the data cutoff will eventually occur. Therefore, when the count reaches the set value, the cutoff recovery process will be started directly. When the data cutoff is about to occur, the cutoff recovery will be carried out in advance. , to avoid data interruption and improve user experience.

When the count has not reached the set value, the next detection cycle is entered. If it is detected that the packet flow is less than the first threshold again, or the current data transmission state is a data interruption state, the statistical time of the detection cycle is restored to the initial value. , and resets the count to zero.

Please refer to FIG. 4 , which is a schematic flowchart of a method for detecting network data interruption according to another embodiment of the present invention.

In this embodiment, in step S103, after judging that the average RTT is greater than or equal to the second threshold, step S401 is performed to count the number of times that the average RTT of the packets is continuously detected to be greater than or equal to the second threshold.

The sequence of step S401 and step S106 is not required, and step S401 may be performed after step S106, before or at the same time.

The above-mentioned network data interruption detection method can start the interruption recovery process in advance before the interruption state occurs, repair the network state in time, and improve the user experience.
