Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of computer networks, and in particular to an ONU problem solution acquisition method, device, equipment and medium for a PON network. BACKGROUND

[0002] Passive optical network (PON) is a kind of telecommunication network that transmits data through optical fiber lines, and is a key technical support for realizing network access technologies such as fiber to the room (FTTR), fiber to the room-business (FTTR-B), etc. FTTR / FTTR-B extends optical fibers to each room and installs optical fiber terminal equipment in each room, which is responsible for converting optical signals into electrical signals. Currently, when the communication process between the terminal equipment and the gateway product ONU has a problem, the terminal equipment manufacturer or the ONU needs to rely on methods such as traversal, comparative analysis, packet capture and protocol analysis to locate the problem. After the problem is located, an upgraded version is arranged to solve it, which not only takes a long time, but also has high maintenance cost. Since the new wireless terminal equipment has extended and supplemented the protocol, the old network cannot recognize the new information type and handle it improperly, which may cause network failure, or since the new gateway ONU has extended and supplemented the protocol, the old wireless terminal equipment cannot recognize the new information type and handle it improperly, which greatly affects the user's use. The existing technology almost all does compatibility processing in the software according to experience accumulation, or iterates the solution to known compatibility problems in the software, and cannot handle changing compatibility problems and new compatibility problems. This leads to high ONU maintenance cost, and when unknown compatibility problems are encountered, users have no way to solve them on their own and can only wait for software upgrade to fix them, which takes a long period of time and has poor experience.

[0022] Please refer to Figure 1 This is a flowchart illustrating a method for obtaining solutions to ONU problems in a PON network, as disclosed in an embodiment of the present invention. Figure 1 As shown, the steps for obtaining a solution to the ONU problem in this PON network can be as follows: S11, Obtain the characteristic information of the terminal device connected to the ONU and the ONU's own configuration information.

[0023] The characteristic information of terminal devices are key parameters reflecting the hardware, system, and communication capabilities of terminal devices, and are the core basis for judging their compatibility with ONU.

[0024] The ONU's own configuration information is configuration data that reflects the ONU's hardware specifications, software status, and communication rules, and serves as a benchmark reference for analyzing compatibility issues.

[0025] Optionally, in one embodiment, obtaining the characteristic information of the terminal device connected to the ONU and the ONU's own configuration information includes: obtaining the device identifier, system parameters, and wireless communication protocol related information of the terminal device by parsing the network protocol messages and communication protocol data interacting between the terminal device and the ONU; and reading the hardware configuration, software version, and wireless communication related configuration parameters of the ONU.

[0026] The acquisition of terminal device characteristic information is generally achieved by parsing the network protocol messages (such as DHCP and WiFi negotiation messages) and communication protocol data (such as TCP / IP and 802.11 series protocols) that the terminal device interacts with the ONU to extract key information.

[0027] Specifically, the MAC address (such as "AA:BB:CC:DD:EE:FF") of the terminal device and the device manufacturer code (such as the "Apple Inc." identifier carried in the message) can be obtained by analyzing the "client identifier" field in the DHCP message; the operating system version (such as "Android 14" and "iOS 17.2") and the hardware model (such as "SM-S918B" corresponding to Samsung Galaxy S23 Ultra) of the terminal device can be extracted from the HTTP request header or DNS message sent by the terminal device; and the wireless protocol version (such as 802.11ax, i.e., WiFi6), the maximum channel bandwidth (such as 160MHz), the modulation mode (such as QAM-1024), and the encryption algorithm support (such as WPA3-SAE) supported by the terminal device can be obtained by analyzing the WiFi association request / response message.

[0028] The acquisition of the ONU's own configuration information is generally achieved by reading the configuration file or system register data stored in the ONU.

[0029] Specifically, the hardware configuration can be obtained by reading the hardware model (such as "HG8546M"), the chip model (such as "MTK MT7621"), and the wireless module specification (such as supporting 2.4GHz / 5GHz dual-band) of the ONU; the software version can be obtained by reading the firmware version (such as "V5.2.3") and the driver version (such as the wireless driver "v2023.05") of the ONU; and the wireless communication related configuration parameters can be obtained by reading the currently effective wireless channel (such as "channel 36" of the 5GHz frequency band), the bandwidth setting (such as "80MHz"), the encryption mode (such as "WPA2-PSK+AES"), and the maximum connection rate limit (such as "1200Mbps").

[0030] These information are the "basic data" for subsequent compatibility analysis: for example, if the terminal device supports WiFi6 (802.11ax) but the ONU firmware version only supports WiFi5 (802.11ac), the protocol version mismatch between the two may cause the connection rate of the terminal device to drop sharply; at this time, the "protocol version" of the terminal device and the "software version + protocol support configuration" of the ONU will become the key basis for the AI model to locate the problem.

[0031] S12, monitoring the network interaction state between the terminal device and the ONU, and determining whether there is a compatibility anomaly.

[0032] This step is based on the feature information of the terminal device and the ONU's own configuration information collected in advance, and by real-time monitoring of the key interaction data between the terminal device and the ONU, it is determined whether the network anomaly is caused by the compatibility problem of the two.

[0033] In an example, the monitored network interaction state can specifically include: connection state: the terminal device repeatedly initiates a connection request but cannot successfully access (such as WiFi display "authentication" after disconnection), or frequently drops after connection (more than 3 times in 1 minute); data transmission state: download / upload rate is abnormally low (terminal device supports 100 Mbps rate, actual is only 10 Mbps), data transmission is lagging (video playback frequently buffers), or data packet error rate is high (PER value exceeds 5%); protocol interaction state: the protocol negotiation message of the terminal device and the ONU cannot be normally responded (such as DHCP request is sent, no address allocation reply is received), or message parsing fails (the ONU cannot identify the protocol extension field sent by the terminal device).

[0034] Optionally, in an embodiment, the network interaction state of the terminal device and the ONU is monitored to determine whether there is a compatibility abnormality, including: collecting network interaction data of the terminal device and the ONU in real time, the network interaction data including connection establishment process data, data transmission quality parameters, and protocol interaction message information; if any of the network interaction data exceeds a preset threshold, starting non-compatibility interference factor investigation; after the non-compatibility interference factor investigation confirms that the non-compatibility interference factor is excluded, if any of the network interaction data still exceeds the preset threshold, determining that the terminal device and the ONU have a compatibility abnormality.

[0035] The core purpose of collecting network interaction data in real time is to collect original data of the whole process of interaction between the terminal device and the ONU, to provide complete data support for subsequent analysis. For example, the following data can be collected: Connection establishment process data: records the connection handshake times of the terminal device and the ONU, authentication time consumption, IP address allocation progress, etc. For example, after the terminal device initiates a WiFi association request, no response is received from the ONU for 3 times of handshake; or the DHCP address allocation time consumption exceeds 10 seconds and is still not completed.

[0036] Data transmission quality parameters: collect packet error rate (PER), transmission rate fluctuation, time delay, packet loss rate, etc. For example, the PER of the terminal device during file transmission continuously reaches 8%; or the terminal device nominally supports a 300 Mbps rate, and the actual average rate is only 20 Mbps, with a fluctuation amplitude of more than 50%.

[0037] Protocol interaction message information: capture protocol negotiation messages and data transmission messages between the terminal device and the ONU, extract message types, field contents, response states, etc. For example, after the ONU receives the 802.11ax protocol extension field sent by the terminal device, a "message format error" response is returned; or the AssociationRequest message sent by the terminal device is not correctly parsed by the ONU.

[0038] Non-compatible interference factor investigation is a key link to exclude the "non-device / protocol mismatch" type of problem in terminal equipment and ONU network anomalies. By verifying external factors such as signals, configurations, and environments one by one, the accuracy of subsequent compatibility anomaly determination is ensured, and misjudgment is avoided. The ONU automatically completes the non-compatible interference factor investigation based on preset investigation rules.

[0039] S13, if it is determined that there is a compatibility anomaly, an inquiry request is sent to an external AI model through an AI interface built in the ONU, and the inquiry request contains terminal equipment characteristic information, ONU configuration information, and compatibility anomaly performance.

[0040] The AI interface built in the ONU is a dedicated channel for communication between the ONU and the external AI model, which is integrated in the ONU firmware in advance, supports standardized data transmission and encrypted interaction, and ensures information security and smooth communication.

[0041] The inquiry request generally needs to contain three types of key information: terminal equipment characteristic information, ONU configuration information, and compatibility anomaly performance, which constitute a complete problem description.

[0042] Compatibility anomaly performance is various abnormal phenomena that occur in the network interaction process due to the mismatch between the terminal equipment and the ONU in terms of hardware specifications, software versions, and protocol support, which directly reflects the specific characteristics of the compatibility contradiction between the two.

[0043] Specifically, the compatibility exceptions can be classified into the following categories: connection type exceptions: problems that occur when the terminal device establishes or maintains a network connection with the ONU, which are essentially caused by connection protocol negotiation failure, incompatible authentication mechanisms, etc.; transmission type exceptions: quality problems that occur during data transmission after connection establishment, which are mainly caused by mismatched transmission protocols, modulation methods, bandwidth configurations, etc.; protocol interaction type exceptions: problems that occur during protocol message interaction and analysis between the terminal device and the ONU, which are caused by incompatible protocol versions, extended fields, message formats, etc. For example, connection type exceptions: the terminal device repeatedly initiates WiFi connection requests but cannot pass authentication; the connection is automatically dropped within 1-3 minutes after successful connection, and the same phenomenon occurs after reconnection; the DHCP address allocation times out, and an effective IP address cannot be obtained (excluding non-compatibility factors such as password errors and weak signals). Transmission type exceptions: the terminal device nominally supports a 300Mbps rate, but the actual transmission rate after connection is only 10-20Mbps; video playback and file download frequently buffer, and the packet loss rate continuously exceeds 3%; the data packet error rate (PER) is higher than 5%, causing repeated retransmission of data transmission. Protocol interaction type exceptions: the ONU cannot parse the 802.11ax protocol extended message sent by the terminal device and returns a "format error" response; during the protocol negotiation process between the terminal device and the ONU, the key fields do not match (such as encryption algorithm support types), causing the negotiation to interrupt; "no response" and "response timeout" occur during message interaction, and interference factors such as network congestion are excluded.

[0044] In an example, assuming that it has been determined that there is a compatibility exception between a certain terminal device and an ONU, the content and sending process of the consultation request are as follows: Terminal device feature information (already collected): Vendor: Apple Model: iPhone14 System version: iOS16.5 Supported wireless protocols: 802.11ax (WiFi6) MAC address: AA:BB:CC:DD:EE:FF ONU configuration information (already collected): Device model: SK-W568 Firmware version: V3.0.1 Wireless configuration: 5GHz band, channel 44, bandwidth 80MHz, encryption method WPA3-SAE Supported wireless protocols: 802.11ac / ax (WiFi5 / 6) Compatibility exception performance (already monitored and determined): Connection state: the terminal device can successfully connect to the ONU, but will be disconnected within 3 minutes after connection, and the same phenomenon occurs after reconnection Data transmission: transmission rate during connection is only 10-20 Mbps (much lower than the nominal 1200 Mbps of terminal equipment) Protocol interaction: ONU fails to parse the AssociationResponse message sent by the terminal equipment multiple times, with a failure rate of 40% Consultation request sending: ONU packages the above three types of information in a standardized format (such as JSON) through the built-in AI interface, generates a consultation request and sends it to the external AI model, for example: { "Terminal equipment feature information": { "Manufacturer": "Apple", "Model": "iPhone14", "System version": "iOS16.5", "Wireless protocol": "802.11ax", "MAC address": "AA:BB:CC:DD:EE:FF" }, "ONU configuration information": { "Model": "SK-W568", "Firmware version": "V3.0.1", "Wireless frequency band": "5GHz", "Channel": 44, "Bandwidth": "80MHz", "Encryption method": "WPA3-SAE", "Supported protocols": "802.11ac / ax" }, "Compatibility abnormal performance": { "Connection problem": "Must be disconnected within 3 minutes after connection, and repeated after reconnection", "Transmission rate": "10-20 Mbps (nominal 1200 Mbps)", "Protocol parsing": "AssociationResponse message parsing failure rate 40%" } }。

[0045] S14, receive the compatibility problem solving solution returned by the external AI model and push it to the user.

[0046] This step is to push the targeted solution generated by the external AI model to the user in an easy-to-operate way, so that the user can quickly obtain and execute it, and finally solve the compatibility problem between the terminal equipment and the ONU.

[0047] The receiving solution is that the ONU receives the structured solution returned by the external AI model through the built-in AI interface, and the content needs to include "terminal device operation guide" and "ONU configuration modification suggestion", to ensure that the user can complete the operation independently without professional technical background.

[0048] The push to the user is to use an intuitive and easy-to-reach push method to avoid complex operation paths, so that users can quickly perceive and obtain solutions. The core is to "reduce the user operation threshold".

[0049] In an example, assuming that the external AI model returns the following solution for the compatibility problem of "iPhone14 (iOS16.5) frequently dropping out and low rate after connecting with SK-W568 type ONU (V3.0.1 firmware)". Problem source: ONU V3.0.1 firmware is not compatible with iOS16.5 system WiFi6 (802.11ax) protocol extension field parsing, resulting in poor connection stability; at the same time, the current 5GHz channel 44 of the ONU is not compatible with the terminal device modulation method, affecting the transmission rate.

[0050] Terminal device operation guide: ① Enter the phone "Settings-Wireless Local Area Network", find the corresponding WiFi name, and click "Ignore this network"; ② Restart the phone WiFi function, search and connect the WiFi again; ③ Select "only use 5GHz band" when connecting.

[0051] ONU configuration modification suggestion: ① Log in to the ONU management page; ② Enter "Wireless Settings-5GHz Configuration", change the channel from 44 to 36, and keep the bandwidth at 80MHz; ③ Save the configuration and restart the ONU wireless module (no need to restart the whole machine).

[0052] In the above-mentioned ONU problem solution obtaining method of PON network, the ONU sends a consultation request to the external AI model through the AI interface, the AI model can integrate real-time updated solutions to similar problems in the industry, and can solve new problems and changing problems; by providing solutions automatically through AI, the human and time investment of manufacturers in after-sales troubleshooting and version upgrade is reduced, without the need to repeatedly iterate software to fix compatibility problems, reducing maintenance costs. Shorten the maintenance cycle; push the solution to the user, the user can directly handle it according to the solution, without waiting for the manufacturer to release a software upgrade package, realizing instant problem solving. Finally, the problem of being unable to handle new and changing terminal device and ONU compatibility problems in the prior art, long processing cycle, high maintenance cost, and user waiting for software upgrade is solved.

[0053] Optionally, in an embodiment, after receiving the compatibility problem solution returned by the external AI model and pushing it to the user, it includes: if it is monitored that the compatibility problem is not solved, the ONU gateway automatically integrates the solution and the latest network interaction data, supplements it to the new consultation request, sends the consultation request to the external AI model again through the built-in AI interface, and obtains the optimized solution.

[0054] After pushing the solution, the ONU continues to monitor the network interaction state of the terminal device and the ONU, and judges whether the original compatibility exception is eliminated (with the previously set exception judgment index as the standard). If the problem is not solved, the ONU automatically integrates two types of key information-the specific content of the first solution (clearly "tried operation") and the latest network interaction data after the problem is not solved (reflecting "abnormal change after trying"). The supplemented information is packaged as a new consultation request, which is sent to the external AI model again through the AI interface to obtain the targeted optimized solution, forming a "consultation-try-reconsultation" closed loop.

[0055] In an example, based on the foregoing "iPhone14 and SK-W568 type ONU connection frequent disconnection, rate too low" scenario, the complete process is as follows: The AI model provides the first solution: the mobile phone ignores the network and reconnects and specifies the 5GHz band, and the ONU changes the 5GHz channel from 44 to 36.

[0056] After the user performs the operation, the ONU continues to collect data and finds that "the disconnection frequency is reduced (from 3 minutes / time to 10 minutes / time), but there is still disconnection; the transmission rate is increased to 50Mbps, which is not normal (should be ≥100Mbps)", and it is determined that the compatibility problem is not completely solved.

[0057] The new consultation request includes: The first solution that has been tried: the complete list of mobile phone operation steps and ONU configuration modification content.

[0058] The latest network interaction data: ① connection state: disconnected 6 times in 1 hour, still triggering the abnormal threshold of "disconnection frequency ≥2 times / hour"; ② transmission rate: average 50Mbps, fluctuation amplitude 30%; ③ protocol interaction: ONU parsing terminal device protocol packet failure rate is reduced to 20% (firstly 40%), but still higher than the normal threshold of 10%.

[0059] The ONU packages the above information to form a new consultation request and sends it to the AI model, and the AI model generates an optimized solution according to the new consultation request.

[0060] Optionally, in an embodiment, the compatibility problem solution returned by the external AI model is received and pushed to the user, including: presenting the solution containing terminal device operation instructions and ONU gateway configuration modification suggestions to the user through webpage pushing or gateway management page display.

[0061] In an example, the specific pushing method is as follows: method one: Portal webpage pushing. After the user's mobile phone connects the WiFi of the ONU, a dedicated webpage is automatically popped up (without manual search), the title shows "Your device and network compatibility optimization suggestion", the webpage is divided into "mobile phone operation steps" and "router (ONU) setting steps", and each step is provided with simple text description; method two: ONU management page display. The user can input the ONU management address through the mobile phone browser, view the complete solution in the "device management-compatibility solution" column, support screenshot saving or one-key jump to the ONU configuration modification page.

[0062] Optionally, in an embodiment, the consultation request is sent to the external AI model through the AI interface built in the ONU, including: the ONU establishes an encrypted communication link with the external AI model through the built-in AI interface; based on the transmission requirements of the encrypted communication link, the terminal device feature information, the ONU itself configuration information and the compatibility abnormal performance are structured, and a standardized data packet is formed; the standardized data packet is packaged as a consultation request containing the whole problem description, and is sent to the external AI model through the encrypted communication link.

[0063] Establishing an encrypted communication link is that the ONU uses the encryption protocol (such as TLS1.3) of the built-in AI interface to establish a dedicated encrypted channel with the server of the external AI model, preventing data from being stolen or tampered in transmission, and ensuring the privacy and security of device information and abnormal data.

[0064] Data structuring is to convert unstructured raw information into standardized fields according to the transmission format requirements (such as JSON, ProtocolBuffers) of the encrypted link, ensuring that the AI model can be directly parsed, and avoiding information loss caused by format confusion.

[0065] Packaging and sending is to integrate the standardized data packet into a complete consultation request containing "problem background + core data", and send it through the encrypted link, ensuring that the AI model can quickly understand the whole problem.

[0066] Optionally, in an embodiment, the network interaction data of the terminal device and the ONU is collected in real time, including: adopting a combination of periodic collection and triggered collection, collecting network interaction data at a preset period when no network interaction state abnormality is detected, and automatically switching to high-frequency triggered collection when network interaction state abnormality is detected.

[0067] The combination of "periodic collection + triggered collection" can not only save ONU hardware resources in normal state, but also accurately capture key data when an exception occurs, achieving a balance between "efficient resource utilization" and "accurate collection of abnormal data".

[0068] The core purpose of periodic collection is to collect basic data at a fixed period when the terminal device interacts normally with the ONU, only to meet the "state monitoring" requirement, and to save the CPU and memory resources of the ONU to the maximum extent without affecting its core communication function. At this time, the collected data can only include "core basic indicators" and does not involve complex messages or instantaneous detailed data. For example, the preset collection period is 30 seconds / time, and only three types of core data are collected when no network interaction state abnormality is detected: terminal device online state, average transmission rate, and packet error rate (PER). For example, when the terminal device is normally connected to the network to watch a video, "online = yes" "average rate = 150 Mbps" "PER = 0.8%" are recorded every 30 seconds, without the need to capture additional protocol messages or instantaneous rate fluctuations, reducing resource occupation.

[0069] The core purpose of triggered collection is to switch to high-frequency collection immediately upon detection of network interaction state abnormality, and to comprehensively capture detailed data (including instantaneous fluctuations and complete messages) when the abnormality occurs, providing complete basis for subsequent analysis of the root cause of the abnormality. The triggering condition is directly related to the "network interaction abnormality" (such as indicator exceeding threshold value, connection state abnormality), and the collection frequency is greatly improved after switching, and the collected data can be expanded to "full-dimensional detailed indicators". For example, the preset PER abnormal threshold is 5%, and when periodic collection detects PER = 6% (triggering abnormality) or detects that the terminal device appears "connection is disconnected and automatically reconnects" (state abnormality), the ONU automatically switches to high-frequency collection mode. The collection period is shortened from 30 seconds / time to 2 seconds / time, and the collected data is added with details such as "protocol interaction complete message", "instantaneous packet loss rate", "handshake response time", "message parsing result", etc. The collection is continued for 10 minutes (covering the complete process of abnormal occurrence and development), ensuring that no key data is missed.

[0070] Please refer to Figure 2 The ONU problem solving solution acquisition device of the PON network can include an acquisition module 21, a monitoring module 22, a sending module 23, and a receiving module 24. The functions of each module are described in detail as follows: The acquisition module 21 is configured to acquire characteristic information of a terminal device connected to the ONU and configuration information of the ONU itself. The monitoring module 22 is configured to monitor the network interaction state between the terminal device and the ONU, and determine whether there is a compatibility abnormality.
