Although on-site testing can comprehensively evaluate the poor quality of WiFi, it relies on manual on-site testing. The effect of poor quality detection depends on the technical ability and experience of the testers and is inefficient. In addition, the poor quality WiFi algorithm based on field strength and interference requires the WiFi device to have built-in soft probes and other plug-in modules, which are not very versatile.

[0053] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0054] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0055] The main solution of the embodiment of the present application is: receiving the Internet access message parameters of the target Internet access terminal; parsing the Internet access message parameters to obtain the data round-trip time from the target Internet access terminal to the content server; according to the Internet access message parameters and the data round-trip time, the first communication time from the target Internet access terminal to the optical network unit is calculated by the broadband remote access server and the network test tool; according to the first communication time, the jitter discrete value of the target Internet access terminal is obtained by discrete value calculation through the optical line terminal; network quality detection is performed according to the preset quality difference jitter threshold and jitter discrete value to obtain the quality detection result. According to the Internet access message parameters, the dial-up message sent by the optical network unit is obtained by querying the broadband remote access server; the dial-up message is parsed to obtain the second communication time from the optical network unit to the broadband remote access server; according to the pre-configured regular dial-up test task, the third communication time from the broadband remote access server to the content server is calculated by the network test tool; according to the data round-trip time, the second communication time and the third communication time, the first communication time from the target Internet access terminal to the optical network unit is calculated. According to the Internet access message parameters, determine the first synchronization packet sent by the target Internet access terminal to the router, the first synchronization confirmation packet returned by the router to the target Internet access terminal based on the first synchronization packet, and the first confirmation packet sent by the target Internet access terminal to the router based on the first synchronization confirmation packet; collect the three-way handshake message between the router and the optical network unit, and determine the second synchronization packet sent by the router to the optical network unit, the second synchronization confirmation packet sent by the optical network unit to the router based on the second synchronization packet, and the second confirmation packet sent by the router to the optical network unit based on the second synchronization confirmation packet.

If the router delay exceeds the router response delay quality threshold, the output quality analysis result is that the router performance is insufficient; and / or if the channel transmission delay exceeds the channel transmission delay quality threshold, the output quality analysis result is that the channel quality is poor; and / or if the optical network unit response delay exceeds the optical network unit response delay quality threshold, the output quality analysis result is that the ONU performance is insufficient; and / or if the router uplink delay exceeds the router uplink transmission delay quality threshold, the output quality analysis result is that the router uplink quality is poor.This solves the problem of poor user experience caused by the inability to locate the specific cause of poor quality when the network quality is poor, and realizes the analysis of network quality, thereby improving the efficiency of network quality analysis. Based on the scheme of the present invention, a network quality analysis method is designed based on the fact that the analysis of network quality in reality relies on manual on-site testing, the effect of poor quality detection depends on the technical ability and experience of testers, and the efficiency is low. The effectiveness of the network quality analysis method of the present invention is verified when analyzing the network quality. Finally, the efficiency of network quality analysis performed by the method of the present invention is significantly improved.

[0056] In this embodiment, for the convenience of description, the following description is made by taking the network quality analysis device as the execution subject.

[0057] Since the network quality of wireless WIFI in the existing technology is the key to affecting the Internet access perception of home broadband customers, how to effectively evaluate WIFI quality perception, discover and solve WIFI quality problems in advance, reduce user complaints, and improve home broadband Internet access quality satisfaction is a difficult point in the exploration and research of home broadband quality operation and maintenance. In the existing solutions, manual on-site testing is usually relied on, and the quality detection effect depends on the technical ability and experience of the testers, and the efficiency is low. In addition, the existing technology cannot accurately locate the root cause of poor WIFI quality, which leads to user dissatisfaction.

[0058] The present application provides a solution, in which, in the operation service end, the quality of the network is analyzed by using the quality difference jitter threshold, so as to quickly obtain the current network quality. At the same time, when the network quality is poor, the quality difference analysis is performed through the communication message of the target Internet terminal to obtain the quality difference analysis result, so as to provide users with better quality services.

[0059] It can be seen from the above embodiments that the present application collects three-way handshake messages between the target Internet terminal, the router and the optical network unit when the network quality of the target Internet terminal is detected to be poor; performs delay analysis through the three-way handshake messages to obtain delay distribution; performs network quality difference analysis on the delay distribution according to a preset delay quality difference threshold to obtain a quality difference analysis result. Thus, when the network quality of the target Internet terminal is detected to be poor, delay analysis is performed through the three-way handshake messages collected between the target Internet terminal, the router and the optical network unit to obtain delay distribution, and finally, quality difference analysis is performed on the delay distribution according to the preset delay quality difference threshold, and the root cause of the current network quality difference is obtained, which solves the problem of poor user experience caused by the inability to locate the specific quality difference cause when the network quality is poor, and improves the efficiency of network quality analysis.

[0060] It should be noted that the execution subject of this embodiment can be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device capable of realizing the above functions, a network quality analysis device, etc. The following takes the network quality analysis device as an example to illustrate this embodiment and the following embodiments.

[0061] Based on this, the present application embodiment provides a network quality analysis method, referring to Figure 1 , Figure 1 This is a flowchart of the first embodiment of the network quality analysis method of the present application.

[0062] In this embodiment, the network quality analysis method is applied to an operation service end, the operation service end includes a router and an optical network unit, and the method includes steps S01 to S04:

[0063] Step S06, when it is detected that the network quality of the target Internet terminal is poor, collecting a three-way handshake message between the target Internet terminal, the router and the optical network unit;

[0064] Before the present embodiment scheme is explained, it should be clear that Wi-Fi is a wireless local area network technology that allows electronic devices to connect to the Internet or communicate with each other through wireless signals. It usually uses 2.4GHz or 5GHz wireless frequency bands for data transmission. Wi-Fi technology is widely used due to its convenience, flexibility and high data transmission rate, especially in indoor Internet access places such as homes and offices. The existing home broadband WiFi quality discovery method is generally achieved by testers on-site testing of WIFI network rate, channel conditions, and signal strength. Although on-site testing can comprehensively evaluate the poor quality of WIFI from all aspects, it needs to rely on manual on-site testing. The quality detection effect depends on the technical ability and experience of the testers, and the efficiency is low. In addition, the poor quality WIFI algorithm based on field strength and interference requires plug-in modules such as built-in soft probes in WIFI devices, which are not very versatile. Not only that, even when poor WIFI quality is detected, the specific cause cannot be accurately located, and subsequent analysis and processing are required, resulting in a poor user experience.

[0065] Therefore, in this embodiment, in order to solve the above problem, when it is detected that the network quality of the target Internet terminal is poor, three-way handshake messages are collected between the target Internet terminal, the router and the optical network unit. Among them, the target Internet terminal in this embodiment refers to the actual user, who is connected to the operation service end through a mobile phone, tablet computer, or other device with Internet access function.

[0066] Step S07, performing network quality detection according to the Internet access message parameters, obtaining the quality detection result, performing delay analysis through the three-way handshake message, and obtaining delay distribution;

[0067] In the above network quality analysis results, the results of good network quality or poor network quality may be obtained. When the network quality is good, it will not be processed and will not affect the actual user's use. However, in the case of poor network quality, if it is not adjusted, it may lead to user complaints. However, in the use of the prior art, the actual quality problem cannot be located, and the manual processing method has the problem of low efficiency. Therefore, in this embodiment, the three-way handshake message between the router and the optical network unit and the three-way handshake message between the target Internet terminal and the router included in the above-mentioned Internet access message parameters are collected, and the delay analysis is performed through the three-way handshake message between the router and the optical network unit and the three-way handshake message between the target Internet terminal and the router to obtain the delay distribution of the current network.

[0068] Step S08, performing network quality analysis on the delay distribution according to a preset delay quality difference threshold to obtain a quality difference analysis result;

[0069] By performing quality analysis on the delay distribution obtained in the above embodiment through the preset delay quality difference threshold, the cause of the current poor network quality can be obtained, and then the corresponding manual processing can be notified to achieve efficient network quality problem processing.

[0070] In this embodiment, when the operation service end receives an Internet access request sent by the target Internet access terminal, it responds to it through the router and simultaneously detects the current network quality. When the network quality is poor, the quality difference is analyzed through the obtained Internet access message parameters and the three-way handshake message between the router and the optical network unit, and the specific cause of the quality difference is obtained, thereby realizing rapid detection of network quality and quickly locating the root cause of the poor quality when the network quality is abnormal, thereby solving the technical problem that the specific cause of the poor quality cannot be located when the network quality is poor, resulting in poor user experience.

[0071] Specifically, the operation service end also includes a content server, a broadband remote access server and an optical line terminal. In the above step S06, when it is detected that the network quality of the target Internet terminal is poor, before the step of collecting a three-way handshake message between the target Internet terminal, the router and the optical network unit, the method further includes:

[0072] Step S01, receiving Internet access message parameters of the target Internet access terminal;

[0073] Step S02, parsing the Internet access message parameters to obtain the round trip time of data from the target Internet access terminal to the content server;

[0074] Step S03, calculating the first communication duration from the target Internet access terminal to the optical network unit through the broadband remote access server and the network testing tool according to the Internet access message parameters and the data round-trip duration;

[0075] Step S04, performing discrete value calculation by the optical line terminal according to the first communication duration to obtain a jitter discrete value of the target Internet access terminal;

[0076] Step S05, performing network quality detection according to a preset quality difference jitter threshold and a jitter discrete value to obtain a quality detection result.

[0077] It should be clear that in actual network use, one optical line terminal OLT is connected to multiple optical modems, so in this embodiment, Figure 2 As shown, according to the actual home broadband customer multi-terminal wireless Internet access network topology, it is assumed that the OLT is connected to p home gateway ONUs, and the wireless terminal devices connected to each home gateway ONU device are sequentially numbered from 1 to n;

[0078] Then, according to the computing power of the content server or DPI server, the communication time T11 to T1n from 1 to n wireless Internet terminals to the home gateway ONU under 1 to p home gateway ONU devices under the OLT is obtained in hours or minutes;

[0079] Then, the difference between the collected communication time from the i-th wireless Internet terminal to the home gateway ONU and the average communication time from all wireless Internet terminals to the home gateway ONU under the OLT is calculated, each difference is squared, and then the sum of the squares of the differences is calculated, and then divided by the number of collections, and finally the square root is taken to obtain the jitter discrete value of the communication time from the target Internet terminal to the home gateway ONU.

[0080]

[0081] Among them, D i is the jitter discrete value of the communication time from the i-th target Internet terminal to the home gateway ONU, T 1i is the communication time from the target wireless Internet terminal to the home gateway ONU, T 1μ is the average communication time from the wireless Internet terminals under OLT to the home gateway ONU, and Q is the number of collection times in a day;

[0082] Finally, by traversing and analyzing D iAnd compare it with the quality difference discrete experience threshold (quality difference jitter threshold) M. Take multiple collections in one day as an example: data can be collected every 10 minutes, and 143 times can be collected within 24 hours. The finer the collection granularity, the higher the accuracy. In actual application, the jitter discrete value D of the communication time from the i-th target Internet terminal to the home gateway ONU can be determined according to the performance of the collection server. i >M, it is determined that the communication time T1 from the i-th wireless Internet terminal device to the home gateway ONU exceeds the poor quality jitter threshold, and the wireless Internet terminal device is determined to have poor indoor wireless Internet quality.

[0083] More specifically, the above step S03, the step of calculating the first communication duration from the target Internet access terminal to the optical network unit through the broadband remote access server and the network testing tool according to the Internet access message parameters and the data round-trip duration, includes:

[0084] Step S031, according to the Internet access message parameters, querying the broadband remote access server to obtain the dial-up message sent by the optical network unit;

[0085] Step S032, parsing the dial-up message to obtain a second communication duration from the optical network unit to the broadband remote access server;

[0086] Step S033, according to the pre-configured periodic dialing test task, a third communication duration from the broadband remote access server to the content server is calculated by a network test tool;

[0087] Step S034, calculating according to the data round-trip time, the second communication duration and the third communication duration to obtain the first communication duration from the target Internet access terminal to the optical network unit.

[0088] In this embodiment, the communication line from the target Internet terminal to the content server is as follows: Figure 3 As shown, it includes the target Internet terminal (wireless Internet terminal), optical network unit ONU, optical line terminal OLT, broadband remote access server BRAS and content server, so the first communication time from the target Internet terminal to the ONU needs to be calculated:

[0089] First, the RTT from the wireless Internet terminal device to the content server is collected through the content server or DPI server deployed by the operator (generally deployed at the provincial network exit). Then the unilateral end-to-end communication time from the wireless Internet terminal device to the content server is T = RTT / 2;

[0090] Then, the home broadband Internet access currently uses PPPoE dial-up for authentication. The dial-up initiator is the home gateway ONU, and the PPPoE responder is the BRAS. By parsing the PPPoE dial-up message from the home gateway ONU to the BRAS, the communication time T2 from the home gateway ONU to the BRAS can be calculated.

[0091] Then, since both BRAS and content server have separate fixed IP addresses, a regular dial test task can be configured on the content server, and the communication time T3 from BRAS to content server can be calculated through ping test.

[0092] Then, based on the unilateral end-to-end communication time T from the wireless Internet terminal device to the content server, the communication time T2 from the home gateway ONU device to the BRAS, and the communication time T3 from the BRAS to the content server, the communication time T1 from the wireless Internet terminal device to the home gateway ONU can be calculated as T-T2-T3. Among them, T2 and T3 are mainly related to the transmission link structure and quality of the operator network, and the fluctuation is not large. Generally, they can be dialed and measured on a daily or weekly basis for analysis and calculation. T can be obtained based on the computing power of the content server or DPI server, and is generally analyzed and calculated at the hourly or minute granularity.

[0093] Finally, the communication time T1 from the wireless Internet terminal device to the home gateway ONU is analyzed and calculated to see whether it exceeds the poor quality jitter threshold. If so, the wireless Internet terminal device is judged to have poor indoor wireless Internet quality, thereby realizing automatic discovery of poor WIFI wireless Internet quality.

[0094] This embodiment adopts the above scheme, specifically, when the network quality of the target Internet terminal is detected to be poor, the three-way handshake message between the target Internet terminal, the router and the optical network unit is collected; the delay distribution is obtained by performing delay analysis through the three-way handshake message; the network quality difference analysis is performed on the delay distribution according to the preset delay quality difference threshold to obtain the quality difference analysis result. Thus, when the network quality of the target Internet terminal is detected to be poor, the delay distribution is obtained by performing delay analysis through the three-way handshake message between the collected target Internet terminal, the router and the optical network unit, and finally the quality difference analysis is performed on the delay distribution according to the preset delay quality difference threshold, and the root cause of the current network quality difference is obtained, which solves the problem that the specific quality difference cause cannot be located when the network quality is poor, resulting in poor user experience, and improves the efficiency of network quality analysis.

[0095] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the above-mentioned embodiment 1 can be referred to the above introduction, and will not be repeated in the following. Figure 4In step S06, in the step of collecting three-way handshake messages between the target Internet terminal, the router and the optical network unit, the network quality analysis method further includes steps S071 to S072:

[0096] Step S061, determining, according to the Internet access message parameters, a first synchronization packet sent by the target Internet access terminal to the router, a first synchronization confirmation packet returned by the router to the target Internet access terminal based on the first synchronization packet, and a first confirmation packet sent by the target Internet access terminal to the router based on the first synchronization confirmation packet;

[0097] Step S062, collecting a three-way handshake message between the router and the optical network unit, and determining, according to the three-way handshake message between the router and the optical network unit, a second synchronization packet sent by the router to the optical network unit, a second synchronization confirmation packet sent by the optical network unit to the router based on the second synchronization packet, and a second confirmation packet sent by the router to the optical network unit based on the second synchronization confirmation packet;

[0098] It should be clear that the three-way handshake message in this embodiment includes a first synchronization packet, a second synchronization packet, a first synchronization confirmation packet, a second synchronization confirmation packet, a first confirmation packet and a second confirmation packet. Therefore, after determining that the current network quality is poor, it is necessary to locate the cause of the poor quality of the network. In this embodiment, since the target Internet terminal needs to perform a three-way handshake interaction with the router and the ONU gateway, the communication message can be obtained for this purpose, such as Figure 5 As shown in FIG. 1 , the TCP three-way handshake process between the wireless Internet terminal, the wireless Internet router, and the ONU gateway is divided into two stages. The first stage is the TCP three-way handshake interaction between the wireless Internet terminal and the wireless Internet router, and the second stage is the TCP three-way handshake interaction between the wireless Internet router and the ONU gateway.

[0099] In the TCP three-way handshake interaction between the wireless Internet terminal and the wireless Internet router, the time when the wireless Internet terminal sends a SYN packet is recorded as Ta1, the time when the wireless Internet router responds to the SYN-ACK packet is recorded as Ta2, and the time when the wireless Internet terminal sends an ACK packet is recorded as Ta3;

[0100] Subsequently, in the three-way handshake interaction between the wireless router and the ONU gateway, the time when the wireless router sends the SYN packet is recorded as Tb1, the time when the ONU gateway responds to the SYN-ACK packet is recorded as Tb2, and the time when the wireless router sends the ACK packet is recorded as Tb3;

[0101] Then, the delay distribution of the current network is obtained by analyzing the above communication packets Ta1, Ta2, Ta3, Tb1, Tb2 and Tb3.

[0102] Specifically, in step S07 in the above embodiment, the step of performing delay analysis through the three-way handshake message to obtain the delay distribution includes:

[0103] Step S071, analyzing the first synchronization packet and the first synchronization confirmation packet to obtain a router response delay;

[0104] Step S072, analyzing the first synchronization confirmation packet and the first confirmation packet to obtain a channel transmission delay;

[0105] Step S073, analyzing the second synchronization packet and the second synchronization confirmation packet to obtain the optical network unit response delay;

[0106] Step S074: Analyze the second synchronization confirmation packet and the second confirmation packet to obtain the router uplink delay.

[0107] Analyze and calculate the six key time points of the two-stage TCP three-way handshake between the wireless Internet terminal, wireless Internet router, and ONU gateway to calculate the wireless Internet router response delay, wireless channel transmission delay, ONU gateway response delay, and wireless Internet router uplink transmission delay;

[0108] More specifically, the above-mentioned wireless Internet router response delay = Ta2-Ta1, wireless channel transmission delay = Ta3-Ta2, ONU gateway response delay = Tb2-Tb1 and wireless Internet router uplink transmission delay = Tb3-Tb2.

[0109] More specifically, the above-mentioned delay quality difference threshold includes a router response delay quality difference threshold, a channel transmission delay quality difference threshold, an optical network unit response delay quality difference threshold, and a router uplink transmission delay quality difference threshold. Therefore, in the above-mentioned step S08, the network quality difference analysis is performed on the delay distribution according to the preset delay quality difference threshold, and the step of obtaining the quality difference analysis result includes:

[0110] Step S081, if the router delay exceeds the router response delay quality experience threshold, outputting the quality analysis result as insufficient router performance; and / or

[0111] Step S082: if the channel transmission delay exceeds the channel transmission delay quality difference empirical threshold, outputting the quality difference analysis result as poor channel quality; and / or

[0112] Step S083, if the response delay of the optical network unit exceeds the optical network unit response delay quality difference empirical threshold, outputting the quality difference analysis result as insufficient ONU performance; and / or

[0113] Step S084: if the router uplink delay exceeds the router uplink transmission delay quality difference empirical threshold, the quality difference analysis result is output as poor quality of the router uplink.

[0114] Assume that the wireless router response delay quality threshold is F1, the wireless channel transmission delay quality threshold is F2, the ONU gateway response delay quality threshold is F3, and the wireless router uplink transmission delay quality threshold is F4;

[0115] By analyzing and calculating the relationship between the wireless router response delay, wireless channel transmission delay, ONU gateway response delay, wireless router uplink transmission delay and the empirical thresholds F1, F2, F3, and F4 of each segment quality difference, the root cause of the poor WIFI quality can be accurately located.

[0116] For example, if the wireless router response delay = Ta2-Ta1>F1, the root cause of poor WIFI quality is due to insufficient performance of the wireless router. Otherwise, this cause is eliminated.

[0117] Similarly, if the wireless channel transmission delay = Ta3-Ta2>F2, the root cause of poor WIFI quality is due to poor wireless channel quality (coverage, interference), otherwise this cause is eliminated;

[0118] If ONU gateway response delay = Tb2-Tb1>F3, the root cause of poor WIFI quality is insufficient ONU gateway performance. Otherwise, this cause is eliminated.

[0119] If the wireless router uplink transmission delay = Tb3-Tb2>F4, the root cause of the poor WIFI quality is due to the poor quality of the wireless router uplink (network port, network cable, negotiated rate configuration). Otherwise, this cause is eliminated.

[0120] This embodiment uses the above scheme to determine the first synchronization packet sent by the target Internet terminal to the router, the first synchronization confirmation packet returned by the router to the target Internet terminal based on the first synchronization packet, and the first confirmation packet sent by the target Internet terminal to the router based on the first synchronization confirmation packet according to the Internet message parameters; collect the three-way handshake message between the router and the optical network unit, and determine the second synchronization packet sent by the router to the optical network unit, the second synchronization confirmation packet sent by the optical network unit to the router based on the second synchronization packet, and the second confirmation packet sent by the router to the optical network unit based on the second synchronization confirmation packet according to the three-way handshake message between the router and the optical network unit. Therefore, when it is detected that the network quality of the target Internet terminal is poor, the delay distribution is obtained by performing delay analysis through the three-way handshake messages collected between the target Internet terminal, the router and the optical network unit, and finally the delay distribution is analyzed according to the preset delay quality difference threshold, and the root cause of the current network quality difference is obtained, which solves the problem that the specific quality difference cause cannot be located when the network quality is poor, resulting in poor user experience, and improves the efficiency of network quality analysis.
