Detailed ways

Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the invention may be embodied in various forms and should not be limited to the embodiments set forth herein.

The embodiments of the present invention are based on performing delay measurement on IP nodes in a mobile environment to obtain a target delay. The target time delay may be the area where the measurement points are located, that is, the target time delay in the area enclosed by the measurement points, or may be the target time delay corresponding to the sub-areas in the area enclosed by the measurement points obtained after clustering the measurement points. The application scenario of the embodiment of the present invention may be a scenario measured on the network side, or an automatic driving scenario, which is not specifically limited here.

Fig. 1 shows the flow chart of the delay testing method provided by the embodiment of the present invention, which is used to test the delay in 4G, 5G, 6G and other mobile communication networks, and can be applied in the Internet of Vehicles. The test equipment or the delay test system may be the delay test equipment or the delay test system on the network side of the operator. The delay test device may be a delay test terminal, such as a mobile phone terminal, a tablet computer, etc., or a terminal device specially used for delay test, or a computer device, such as a desktop computer, a notebook computer, etc. The delay test system includes a delay test terminal (the delay test terminal has no mobile communication function) and a gateway; the gateway can be a mobile phone, a Pad or a modem, which is used to connect to networks including but not limited to WIFI, 4G, 5G, 6G, etc. . The delay test terminal and the gateway can be connected through USB or mobile phone WIFI hotspot. As shown in Figure 1, the method includes the following steps:

Step 110: Obtain the IP address of the IP node to be measured.

Wherein, the IP information of each IP node in the routing segment from the delay testing terminal or the delay testing system to the target address can be obtained through routing instruction tracking; For the IP information of the IP nodes, the list file may be preset; the IP information of each IP node may also be obtained by obtaining the IP information input by the user. Wherein, the IP information includes information such as an IP address and an IP name. In the embodiment of the present invention, the target address may be a domain name, such as www.abc123456.com.

In the embodiment of the present invention, the IP address of each of the IP nodes in the routing segment (path) to the target address is traced by obtaining the target address through the data packet in the routing instruction sent. Specifically, the data packet may be an IP message; send the IP message to the target address; receive feedback information from each of the IP nodes to the IP message; determine the IP address of each of the IP nodes according to the feedback information IP address. The feedback information also includes the IP node name of the IP node.

Wherein, the routing instruction includes any one of tracert routing instruction, traceroute routing instruction, etc., which can be set according to specific scenarios. For example, for a Windows terminal, use the tracert routing command to trace the routing segment of the target address. The tracert routing command in the embodiment of the present invention can trace up to 30 nodes. The Linux terminal can trace the target address routing segment through the traceroute routing command.

In the embodiment of the present invention, after obtaining the IP address of each IP node, each IP node is structured and stored separately, each IP node corresponds to an IP structured data, and the IP structured data includes a plurality of structured nodes , each structured node is respectively used to store the information of the IP node (such as IP node name, IP address), measurement delay value, measurement times, geographical location and other information. Among them, the structured storage can be array format, single/double linked list, tree and other structures. Wherein, the measurement delay value may be initialized to 0, indicating that it is not measured.

In an embodiment of the present invention, after acquiring the IP address of the IP node, the method includes: generating an IP linked list corresponding to the IP node. The IP linked list includes a plurality of linked list nodes, and each linked list node is used to store the information of the IP node (such as IP node name, IP address), measurement delay value, measurement times, geographical location and other information. Wherein, the delay value can also be an array, and the linked list node also includes a measurement flag bit for recording the number of measured delay values. The linked list node also contains a pointer to another measured delay value of the IP node.

Step 120: Perform delay measurement on the IP address at measurement points at different locations to obtain a plurality of measurement information of the IP node corresponding to the measurement point, where the measurement information includes a measurement point delay value.

Wherein, the area where the measuring points at different positions are located is the enclosing area of the measuring points, and the enclosing area of the measuring points is the area surrounded by the boundaries of the measuring points at different positions, such as the edge located in the measuring points at different positions The area surrounded by successively connected lines between the measurement points can also be the area formed by drawing a circle with the distance between the two farthest measurement points as the diameter, and the circle includes all the measurement points. During the measurement, it is not clear which area the multiple locations are located in, and there is no need to care about the specific areas of the multiple locations, and it is only necessary to measure the delay value for different locations.

Wherein, in the embodiment of the present invention, since it is in a mobile state, the location of sending the data packet to the IP node is different from the location of receiving the data packet fed back by the IP node. The measurement point delay value is related to the measurement speed, wherein the measurement speed is a constant speed, and the measurement speed can be set according to specific scenarios.

In the embodiment of the present invention, the measured delay value of the IP node is acquired through an Internet packet explorer. Specifically, the Internet packet explorer is a PING command. PING (Packet Internet Groper), Internet packet explorer, a program for testing network connection volume. PING is a service command working in the application layer of the TCP/IP network architecture. It mainly sends an ICMP (Internet Control Message Protocol) Echo request message to a specific destination host to test whether the destination station is reachable and Learn about its status. PING is the network delay of your computer linking to the Internet, generally in milliseconds, the larger the number, the more stuck the network. Generally speaking, good: packet loss rate = 0 and delay is less than 10ms; normal: packet loss rate is less than 2% or delay <100ms; abnormal: packet loss rate is greater than 2% or delay is greater than 100ms; interruption: packet loss rate is 100%.

As shown in Figure 2, it shows the time delay of different geographical locations of the access network. If the measurement results do not take into account the influence of the measurement values of different geographical locations, in the background of hybrid networking, the data of time delay measured at fixed locations There will be distortion, and it will be impossible to locate the problem and optimize the delay index. For example, for the areas covered by 5G base stations AAU1, AAU2, and AAU3, the delay is 35ms, and the test delay for the areas covered by AAU4, AAU5, and AAU6 is 20ms (refer to Figure 3). The two are obviously different. However, it is difficult to directly specify and distinguish the boundary of the coverage area of the wireless signal, so the embodiment of the present invention directly performs multiple delay measurements on the IP node at multiple different locations to obtain the measured delay value. Wherein, the embodiments of the present invention do not specifically limit specific positions of different positions, and corresponding settings may be made according to specific scenarios during measurement. In the embodiment of the present invention, for each measurement, when the number of measurements reaches the N threshold or the measurement duration exceeds the T second duration threshold or the user issues an instruction to terminate the measurement, the measurement is terminated. For example, the threshold of N times can be set to 2000 times, and the threshold of T seconds can be set to 30 minutes. storing the multiple measured delay values obtained by multiple measurements in the corresponding linked list nodes in the IP linked list. In the embodiment of the present invention, during each test, the location information measured this time, including longitude and latitude information, is also recorded, and the location information is also correspondingly stored in the corresponding linked list node in the IP linked list. As shown in Figure 3, it shows the delay schematic diagram of different IP nodes, for the delay test, the delay test terminal to the base station, the access ring in the mobile network, the core layer (metropolitan area), the core layer (provincial level) ), the delay between nodes such as P-GW, edge server, and cloud server.

Step 130: Determine the target delay of the IP node in the area enclosed by the measurement point according to the plurality of measurement information.

Among them, the RFC2544 protocol gives the definition of latency (Latency): send a certain number of data packets, record the time T1 when the intermediate data packets are sent, and the time T2 to reach the receiving port after being forwarded by the test equipment, and then calculate according to the following formula :

For store/bit-forward devices: Latency=T2-T1

T2: the time when the first bit of the output frame arrives at the output port;

T1: The time when the last bit of the input frame arrives at the input port.

In the embodiment of the present invention, the time delay value of the calculation measurement point can be calculated according to different positions using the mean value method. Since PING includes a two-way time delay of sending and receiving, the target time of the IP node is Delay=PING average delay/2; For the delay test system, because it includes the initialization delay between the delay test terminal and the gateway, the target delay of the IP node=PING average delay/2-initialization delay.

Wherein, the target time delay in the area enclosed by the measurement points is an average value of the time delay values of the measurement points corresponding to each measurement point in the area enclosed by the measurement points.

In the embodiment of the present invention, by automatically tracking each IP node in the routing segment of the target address, and automatically measuring the value of the delay index from the mobile terminal to the server, especially the node related to edge computing, by measuring the delay of each IP node in a mobile environment, further Blindly measure the delay index in the enclosed area of the measurement point, and complete the evaluation of the network delay index by calculating the delay value based on the recorded measurement value. The embodiment of the present invention realizes the beneficial effect of performing time delay measurement in a mobile environment, making the time delay measurement value more reasonable and accurate.

Fig. 4 shows a schematic flowchart of a delay testing method provided by another embodiment of the present invention. The delay testing method of the embodiment of the present invention is used to test the delay in mobile communication networks such as 4G, 5G, 6G, etc., can be applied in the Internet of Vehicles, and is executed by the network-side delay test equipment or delay test system, which can be operated Provider’s latency testing equipment or latency testing system on the network side. The delay test device can be a delay test terminal, such as a computing device such as a mobile phone terminal, a tablet computer, or a terminal device specially used for a delay test, or a computer device, such as a desktop computer, a notebook computer, and the like. The delay test system includes a delay test terminal (the delay test terminal has no mobile communication function) and a gateway; the gateway can be a mobile phone, a Pad or a modem, which is used to connect to networks including but not limited to WIFI, 4G, 5G, 6G, etc. . The delay test terminal and the gateway can be connected through USB or mobile phone WIFI hotspot. The difference between the delay test method of the embodiment of the present invention and the delay test method shown in Figure 1 is that the embodiment of the present invention subdivides the encircled area of the measurement points, and encloses the measurement points by clustering the measurement information The area is divided into multiple clustering areas, and the target latency corresponding to the multiple clustering areas is determined. As shown in Figure 4, the method includes the following steps:

Step 210: Obtain the IP address of the IP node to be measured.

Wherein, the specific implementation manner of the step 210 is consistent with the step 110 in the above method embodiment, and will not be repeated here.

Step 220: Perform delay measurement on the IP address at different measurement points to obtain a plurality of measurement information of the IP address, the measurement information including the coordinates of the measurement point and the delay value of the measurement point.

In the embodiment of the present invention, the coordinates of the measurement points are also recorded during the measurement.

Step 230: Clustering according to the measurement information of the measurement points to obtain a plurality of cluster regions of the measurement points.

Wherein, after obtaining multiple measurement time delay values, spatial clustering can be performed according to different measurement time delay values corresponding to different positions, and analysis and obtaining target time delays in each area include: clustering the multiple time delay measurement values class to obtain the clusters of delay measurement values corresponding to each area; and determine the target delay of the IP node in each area according to each delay measurement value in the cluster. Therefore, during measurement, it is not necessary to care about specific areas in multiple different locations, and it is only necessary to measure time delay values at different locations. Specifically, acquiring the latitude and longitude information of each location when performing delay measurement; clustering the measured delay values according to the latitude and longitude information to obtain a plurality of clusters; determining the IP in each cluster The target delay corresponding to the node.

In the embodiment of the present invention, the measurement information is clustered by adopting the DBSCAN clustering method or the KNN clustering method to obtain a plurality of cluster regions of the measurement points.

Wherein, in one embodiment of the present invention, the DBSCAN clustering algorithm is used for clustering to obtain clusters. DBSCAN clustering algorithm Density-Based Spatial Clustering of Applications with Noise, a density-based clustering method with noise) is a very typical density clustering algorithm, and K-Means, BIRCH, which are generally only suitable for convex sample sets Compared with clustering, DBSCAN can be applied to both convex sample sets and non-convex sample sets. The significant advantage of DBSCAN algorithm is that the clustering speed is fast and it can effectively deal with noise points and find spatial clusters of arbitrary shapes. Input two-dimensional data containing multiple measured time delay values corresponding to the above-mentioned different positions. Through this clustering method, multiple measurement delay values with similar positions and similar measurement delay values are clustered together to form a cluster, so that the measurement delay values with similar positions, that is, the same area, are clustered together.

The DBSCAN clustering algorithm performs clustering, and the specific steps of obtaining the clusters include: setting the cluster radius e, the minimum number of MinPts, and outputting multiple clusters. Among them, the clustering radius e is the neighborhood radius for searching for its neighbors for a specific object in a given two-dimensional data set. Perform the following steps:

Determine whether the current point is a core point; the current point represents the measured delay value obtained by the IP node at the target position; the target position is any one of the different positions;

When the current point is the core point, find out all other points that are density-reachable from the current point to form a cluster, and at least MinPts objects are included in the cluster;

When the current point is not a core point, it is an edge point, and then the next point is searched until all points are processed. Finally, a plurality of cluster regions of the measurement points are obtained.

Step 240: Determine the target delay of the IP address in the cluster area within the area enclosed by the measurement point according to the delay measurement values in the cluster area.

In the embodiment of the present invention, the calculation method of the measurement point delay value is consistent with the specific calculation method of step 130, and will not be repeated here.

Wherein, after the clustering is performed by the clustering algorithm, the target delay is obtained according to the mean value method according to the cluster cluster, and the delay array of the nodes in the IP linked list is updated, wherein, each measured delay value=ping average delay/2. In this way, the measured delay values in the same physical area are clustered together, so as to determine the target delay of the IP address in the cluster area within the encircled area of the measurement point, wherein the target time delay The delay is the average value of the delay values of the measurement points of the IP address in the cluster area. When the target delay of IP nodes in the cluster is large, it can be determined that there may be faults in the IP nodes in this area, so as to further analyze the cause of the faults.

Fig. 5 shows a schematic flowchart of a delay testing method provided by another embodiment of the present invention. The delay testing method of the embodiment of the present invention is used to test the delay in mobile communication networks such as 4G, 5G, 6G, etc., is executed by a mobile terminal, and can be applied to a vehicle terminal in the Internet of Vehicles. The vehicle terminal may be a terminal device including delay testing in the self-driving vehicle. The vehicle terminal includes a delay test device (the delay test device has no mobile communication function) and a gateway; the gateway can be a mobile phone, a Pad or a modem for connecting to networks including but not limited to WIFI, 4G, 5G, 6G, etc. The delay test terminal and the gateway can be connected through USB or mobile phone WIFI hotspot. The difference between the delay test method of the embodiment of the present invention and the delay test method shown in Figure 1 and Figure 4 is that the embodiment of the present invention is applied to a mobile terminal and executed by the mobile terminal, which can be a mobile For vehicle terminals, the delay test method interacts with the mobile environment, including the measurement speed of the mobile terminal, and then performs regional delay measurement by adjusting the measurement speed. As shown in Figure 5, the delay testing method of the embodiment of the present invention includes the following steps:

Step 310: Obtain the IP address of the IP node to be measured.

Wherein, the specific implementation manner of step 310 is consistent with the specific implementation manner of step 110 in the above-mentioned embodiment, and will not be repeated here.

Step 320: Perform delay measurement on the IP address at different measurement points to obtain a plurality of measurement information of the IP address, the measurement information includes the coordinates of the measurement point, the delay value of the measurement point, and the measurement speed.

In the embodiment of the present invention, the measurement information further includes the coordinates of the measurement point and the measurement speed. The measurement coordinates and the measurement speed may respectively be the coordinate position and speed of the vehicle terminal during real-time measurement. In particular, the measurement coordinates may also be coordinates of the driving coordinate system.

In the embodiment of the present invention, the calculation method of the measurement point delay value is consistent with the specific calculation method of step 130, and will not be repeated here.

Step 330: Adjust the measurement speed according to the time delay value of the measurement point, and continue the time delay measurement according to the adjusted measurement speed to obtain new measurement information.

Wherein, when the delay measurement is performed on the same IP node in a mobile state, since the positions of sending and receiving the measurement data packets are different, the measurement speed will affect the delay value. Adjust the measurement speed according to the time delay value of the measurement point, continue the time delay measurement according to the adjusted measurement speed, and obtain new measurement information, including: if the time delay value of the measurement point exceeds the set threshold, reduce the measurement speed measurement until the set Set the minimum measurement speed or the time delay value of the measurement point is lower than the set threshold; if the time delay value of the measurement point is lower than the set threshold, increase the measurement speed measurement until the highest measurement speed is set or the time delay value of the measurement point is higher than the set threshold. Set the threshold. Wherein, the set threshold may be a threshold set by an operator or an automobile manufacturer for a specific scenario of a vehicle terminal according to a network test standard, which is not specifically limited in this embodiment of the present invention.

Specifically, the delay test device sends a speed adjustment request to the central control unit of the vehicle terminal to adjust the movement speed.

After the adjustment, the delay measurement is continued to obtain new measurement information, and the new measurement information also includes the coordinates of the measurement point, the delay value of the measurement point, and the measurement speed.

Step 340: Clustering according to the new measurement information of the measurement points to obtain cluster areas of a plurality of measurement points.

In the embodiment of the present invention, the measurement information is clustered using the DBSCAN clustering method or the KNN clustering method to obtain cluster cluster areas of multiple measurement points, and the specific clustering method is the same as the steps in the above-mentioned embodiments 230 are similar, and will not be repeated here. After clustering, multiple cluster regions are obtained.

Step 350: Determine the target delay and the corresponding average measurement speed of the IP nodes in each cluster area within the enclosing area of the measurement point.

Wherein, after the clustering is performed by the clustering algorithm, the target time delay of the clustering cluster area is obtained according to the mean value method. In this way, the measured delay values in the same physical area are clustered together, so as to determine the target delay of the IP address in the cluster area within the encircled area of the measurement point, wherein the target time delay The delay is the average value of the delay values of the measurement points of the IP address in the cluster area. And calculate the average measurement speed in the cluster area. The average measurement speed is obtained by calculating the mean value of the adjusted measurement speed in the cluster.

After determining the target time delay and the corresponding average measurement speed of the IP nodes in each cluster area within the encircled area of the measurement point, sending the target time delay and the average measurement speed to the mobile terminal. The mobile terminal receives the target time delay and the average measured speed, and adjusts the driving state according to the target time delay and the average measured speed.
