Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of communication, in particular to an ONU gateway access OLT device method and device of PON network, equipment and medium. BACKGROUND

[0002] In the existing GPON access network, the GPON access network is mainly composed of an OLT device and an ONU device, and the configuration, management and control of the ONU device are usually realized through an optical network unit management control interface (ONU management control interface) management and control module of the OLT device. However, there may be inconsistent understanding of the standard in the implementation of the optical network unit management control interface management and control module of different manufacturers, resulting in compatibility problems when the ONU device interfaces different manufacturers' OLT devices In the PON networking mode, the OLT device is point-to-multipoint networking with the ONU, and the basic principle of communication is that the downlink data is divided into logical channels by time slots, and the terminal user data on all ONUs is time-division multiplexed on the corresponding time slots and broadcasted, and the ONU side selects and collects the data on the corresponding logical channel. The uplink data uses a device supporting burst optical signals on the ONU, and each ONU transmits the uplink data of the terminal user to the OLT device side in a predetermined time slot window according to the time-division multiplexing principle. However, there are interoperability problems between the ONU device and the OLT device in the existing PON system, mainly manifested as: 1. Different manufacturers define a large number of private optical network unit management control interface management entities in the ONU device production process for easy management, which is difficult to realize unified management and control; 2. Different manufacturers have different understandings of the optical network unit management control interface management entity parameters, causing the differentiation of the ONU device, which makes it difficult to realize a unified management and control scheme; 3. The optical network unit management control interface protocol realizes different functions at L2, L3 and above by combining and associating the optical network unit management control interface management entities in the ONU device. Due to the difference of the ONU devices of different manufacturers, the combination and association modes of the optical network unit management control interface management entities of the ONU devices of different manufacturers are different, and the OLT device needs to adapt to various combination and association modes of the optical network unit management control interface management entities, increasing the complexity of management and control. Therefore, there is a compatibility problem when the ONU gateway accesses the OLT device in the prior art. SUMMARY

The appearances of the phrase "in one embodiment" or "in some embodiments" in various places within specified

[0023] It should be understood that the magnitude of the serial number of each step in the following embodiments does not mean the order of execution, and the execution order of each process should be determined according to its function and inherent logic, and should not constitute any limitation on the implementation process of the embodiments of the application.

[0024] In order to illustrate the technical solutions of the application, the following will be described by specific embodiments.

[0025] Please refer to Figure 1 As shown in the drawings, Figure 1 A flowchart of a method for accessing an OLT device of an ONU gateway of a PON network according to an embodiment of the application is shown in FIG. 1, which includes the following steps: S11: initializing device configuration information.

[0026] This step refers to a preprocessing operation of resetting and configuring the basic readiness of the software and hardware running parameters, protocol analysis module, data storage configuration, etc. of the ONU gateway before it starts to connect the OLT device, so as to provide a unified and clean basic running environment for subsequent receiving of OLT device feature information, matching of optical network unit management control interface management entity, and execution of access operation. It is a necessary step before the ONU gateway realizes the adaptive access to the OLT device.

[0027] After the ONU gateway connects the OLT device of another manufacturer last time, the adaptive parameters, configurations, protocol analysis rules, etc. of the last OLT device will be left. If it directly connects the new OLT device, it may interfere with the identification and matching of new feature information, resulting in identification failure and access error.

[0028] In an embodiment, the device configuration information is initialized, specifically including: reading and resetting the preset ONU default basic parameters; loading a standardized optical network unit management control interface protocol library, which is used to analyze the OLT device feature information and process the instructions of the optical network unit management control interface management entity.

[0029] In an example, in a specific implementation scenario, the operation of initializing the device configuration information specifically includes at least one of the following operations: 1. resetting the basic operation parameters of the ONU gateway, emptying the residual data such as VendorID, private management entity configuration, interface communication parameter of the previous access OLT device cached in the gateway, and restoring to the standard parameter state preset at factory; 2. reading and loading the standardized configuration file built-in the ONU gateway, which contains the basic protocol rules adapted to OLT devices of various manufacturers, the general analysis logic of the optical network unit management control interface management entity, and the database calling permission configuration; 3. starting and initializing the optical network unit management control interface protocol analysis module of the ONU gateway and the built-in device model database, so that the analysis module has the capability of identifying the VendorID and private optical network unit management control interface management entity configuration issued by the OLT device, and the database is in a ready state of real-time calling and matching; 4. resetting the PON port communication configuration of the ONU gateway, unifying the signal receiving rules of the PON port, and ensuring that various device characteristic information issued by the OLT device side can be stably and accurately received.

[0030] S12: receiving the OLT device characteristic information issued by the OLT device side.

[0031] Receiving the OLT device characteristic information issued by the OLT device side refers to the process that the ONU gateway, after completing initialization, establishes an initial communication link with the OLT device through the PON interface, and receives the core information actively issued by the OLT device to identify its own identity and protocol adaptation requirements; this step is the basis for the ONU gateway to identify the OLT device manufacturer / model and judge the supportability.

[0032] In an embodiment, the OLT device characteristic information includes at least one of the following: VendorID and private optical network unit management control interface management entity configuration.

[0033] In actual scenarios, generally, different OLT device manufacturers adopt different optical network unit management control interface management entities, and OLT devices of different models of the same OLT device manufacturer adopt the same optical network unit management control interface management entity. Therefore, it is necessary to identify the manufacturer of the OLT device from the OLT device characteristic information, and the VendorID and private optical network unit management control interface management entity configuration are directly associated with the manufacturer.

[0034] VendorID is a unique identification predefined by the manufacturer, which can directly locate the OLT equipment manufacturer (such as Huawei and ZTE) for the ONU gateway, without complex analysis, greatly improving the identification efficiency and avoiding adaptation failure caused by identification deviation; the private optical network unit management control interface management entity configuration is a function module configuration defined by the manufacturer, which can be used as a "replacement identification basis" in the case of missing VendorID (such as some old OLT devices do not support VendorID delivery), to ensure the identification coverage of the ONU gateway to various OLT devices; the composition logic of "at least one" takes into account the communication protocol specifications of different OLT devices (new OLT devices support VendorID delivery, and old OLT devices only support private optical network unit management control interface management entity configuration), so that the adaptation range of the ONU gateway covers more scenarios, further strengthening the solution effect of the compatibility problem.

[0035] In an example, in an actual PON network communication scenario, the ZXA10C620 type OLT equipment of ZTE delivers feature information to the ONU gateway, only carrying VendorID: "ZTE-202405" (where "ZTE" is the abbreviation of ZTE manufacturer, and "202405" is the equipment model code); after receiving, the ONU gateway directly matches the built-in equipment model database through the VendorID, determines that the connected is the ZXA10C620 type OLT equipment of ZTE manufacturer, and then calls the special optical network unit management control interface management entity of ZTE to execute the access operation.

[0036] In another example, the OLT equipment produced by some early small manufacturers does not support VendorID delivery, and the feature information it delivers to the ONU gateway is the private optical network unit management control interface management entity configuration: "private MEID: 0x0036 (port rate control entity) + configuration parameter: 10Gbps downlink bandwidth"; this private MEID and corresponding parameter are unique to the OLT equipment of this manufacturer, and after receiving, the ONU gateway matches and determines the model and access adaptation rule of the OLT equipment through the pre-stored "small manufacturer private ME configuration and equipment model correspondence table" in the built-in equipment model database.

[0037] S13: Based on the OLT equipment feature information, combined with the built-in equipment model database, judge the OLT equipment access supportability.

[0038] After receiving the equipment feature information delivered by the OLT equipment side, the ONU gateway takes the feature information as the matching retrieval basis, calls the pre-built-in equipment model database of itself, compares and matches the received feature information with the pre-stored feature information of OLT equipment of each manufacturer in the database, and finally determines whether the current OLT equipment to be connected can be adapted and accessed by the ONU gateway.

[0039] In an example, the ONU gateway receives the feature information issued by the Huawei MA5800 model OLT device, and the feature information is VendorID: HUAWEI-MA5800. Then, the ONU gateway calls the built-in device model database, in which a list of VendorIDs of all OLT device models of the Huawei brand and corresponding access support marks are pre-stored. The received HUAWEI-MA5800 is accurately matched with the list in the database. The matching result is that the VendorID exists in the database and is marked as supporting access. Therefore, it is directly determined that the Huawei OLT device supports access.

[0040] S14: According to the judgment result, a corresponding optical network unit management control interface management entity is matched to perform an access operation.

[0041] After the ONU gateway completes the determination of the access supportability of the OLT device, according to the determination result, an optical network unit management control interface management entity that is adapted to the current OLT device to be accessed is accurately matched in the optical network unit management control interface management entity resource pool pre-stored in the ONU gateway, and the matched optical network unit management control interface management entity is called to perform a series of access-related operations such as link negotiation, parameter configuration, service adaptation, communication link establishment, and the like with the OLT device.

[0042] In an example, the ONU gateway receives the VendorID of the Huawei MA5800 model OLT device, which is HUAWEI-MA5800. After matching with the built-in device model database, it is determined that access is supported. Then, a Huawei private optical network unit management control interface management entity pre-stored in the ONU gateway is matched and called. The management entity pre-stores the protocol interaction rules, private parameter configuration logic, and service link establishment process of the Huawei OLT device. Through the private optical network unit management control interface management entity, the ONU gateway and the Huawei OLT device complete access configuration such as bandwidth negotiation, port binding, and service opening, and finally complete stable link establishment and realize normal communication.

[0043] In another example, if the feature information of the ZTE ZXA10C620 model OLT device is received and it is determined that access is supported, the ONU gateway matches and calls a ZTE private optical network unit management control interface management entity to perform an access operation, adapts to the private protocol rules of the ZTE OLT device, and completes accurate access.

[0044] The ONU gateway access OLT device method of the PON network, by performing device configuration initialization on the ONU gateway, receiving device characteristic information issued by the OLT device side, combining the built-in device model database to complete accurate judgment of OLT device access support, and matching the corresponding optical network unit management control interface management entity according to the judgment result to perform access operation, without manual configuration or version recompilation of the ONU gateway, adapting to OLT devices of different manufacturers and different models, effectively solving the technical problem of poor compatibility of ONU gateway access OLT device in the prior art.

[0045] In an embodiment, based on the OLT device characteristic information, the built-in device model database is combined to judge the OLT device access support, including: matching the OLT device model in the built-in device model database according to the VendorID, if the matching is successful, it is determined that the OLT device supports access, otherwise it is determined that it does not support; if there is no VendorID, the OLT device model in the built-in device model database is matched based on the private optical network unit management control interface management entity configuration, if the matching is successful, it is determined that the OLT device supports access, otherwise it is determined that it does not support.

[0046] This embodiment is a hierarchical priority automatic matching judgment logic: taking the VendorID as the first priority matching basis, and taking the private optical network unit management control interface management entity configuration as the second priority matching basis, the built-in device model database is searched in order of "VendorID first, private optical network unit management control interface management entity configuration second", to complete the judgment of OLT device access support. The VendorID has "manufacturer uniqueness and accurate identification", which can realize fast and accurate matching of the OLT device; the private optical network unit management control interface management entity configuration has "manufacturer exclusive association", which can cover the old / non-standard OLT device scene where the VendorID is missing, and through hierarchical priority design, the judgment efficiency and adaptation coverage are considered.

[0047] In an example, the ONU gateway receives the characteristic information issued by the Huawei MA5800 type OLT device, which contains the VendorID: "HUAWEI-MA5800", and no private optical network unit management control interface management entity configuration; the built-in device model database pre-stores a "Huawei brand OLT device VendorID list", which contains "HAUWEI-MA5800" and is marked as "supporting access". The ONU gateway preferentially extracts the VendorID, calls the built-in device model database for matching, and searches that the VendorID exists and supports access; because the first priority matching is successful, there is no need to enter the second priority judgment.

[0048] In another example, the ONU gateway receives the feature information issued by the early ZTE ZXA10C320 type OLT device, without VendorID, and only contains the private optical network unit management control interface management entity configuration: "private MEID: 0x0032 + service binding parameter: GPON mode"; the built-in device model database pre-stores the "ZTE old OLT device private ME configuration and model corresponding table", in which "0x0032 + GPON mode" corresponds to ZXA10C320 type, marked as "support access". The ONU gateway fails to extract the VendorID, and then analyzes the model of the OLT device according to the received private optical network unit management control interface management entity configuration, compares it with the built-in device model database, and matches successfully, so as to determine that the ONU gateway supports the access of the ZTE ZXA10C320 type OLT device.

[0049] In an embodiment, according to the judgment result, the corresponding optical network unit management control interface management entity is matched to perform the access operation, including: if the determination result is that the OLT device is not supported to access, a preset standard optical network unit management control interface management entity is used to perform the access operation.

[0050] After the ONU gateway completes the OLT device access support determination, there are two branches of matching access logic, one is to determine to support access, and the corresponding private optical network unit management control interface management entity of the OLT device model is matched to perform accurate access; the other is to determine not to support access, and the access process is not terminated, but the standard optical network unit management control interface management entity pre-built in the ONU gateway is called, and the general access operation is performed based on the industry unified optical network unit management control interface protocol standard.

[0051] The standard optical network unit management control interface management entity is a basic type optical network unit management control interface management entity developed according to the general standard of PON network industry, without any manufacturer private configuration and model exclusive restriction, and is a general protocol interaction module that can be recognized by all OLT devices.

[0052] In an embodiment, after the access operation is completed, the ONU gateway further includes: generating an ONU interface capability set template full network identifier based on the MD5 algorithm or the CRC algorithm, and sending the identifier to the OLT device through the optical network unit management control interface protocol, so as to establish the optical network unit management control interface management connection.

[0053] The embodiment is a core step of subsequent link reinforcement and compliance connection after the ONU gateway and the OLT device complete basic access operation; the ONU gateway first performs encryption operation on its own interface capability set template (including core hardware capability information of the ONU, such as port rate, service bearing capability, protocol compatible version, bandwidth adaptation threshold, etc.) through MD5 algorithm or CRC algorithm, generates a unique network-wide identifier, and then actively sends the identifier to the OLT device through the optical network unit management control interface protocol, and the OLT device verifies and confirms the identifier, and then establishes a stable, compliant and bidirectional controllable optical network unit management control interface control connection with the ONU gateway. The MD5 algorithm and the CRC algorithm are mature hash verification / data verification algorithms in the industry, which are used to ensure the uniqueness, integrity and tamper resistance of the generated identifier; the optical network unit management control interface protocol is the only compliant communication protocol for the ONU and the OLT device to complete control instruction interaction.

[0054] In an example, the ONU gateway completes access operation with the Huawei MA5800 type OLT device through the Huawei private optical network unit management control interface management entity, determines that access is supported and that the basic communication link has been established; the ONU gateway is a commercial gigabit type, and the interface capability set template includes: downlink gigabit rate, 8 service ports, GPON protocol V3 version, and maximum bearing bandwidth 1000 Mbps. The ONU gateway retrieves its own interface capability set template, performs encryption hash operation on all core information of the template through MD5 algorithm, and generates a unique 32-bit network-wide identifier: 789a6b5c4d3e2f1g9s8d7f6g5h4j3k2l1. The ONU gateway actively sends the MD5 generated network-wide identifier to the Huawei MA5800 type OLT device through the optical network unit management control interface protocol. The OLT device receives the identifier, completes MD5 reverse verification, confirms that the identifier is not tampered and that the interface capability of the ONU matches the configuration of the OLT device, and then returns a confirmation instruction to the ONU. After the two parties complete instruction interaction, a stable optical network unit management control interface control connection is established.

[0055] In another example, the ONU gateway determines that a certain small non-standard OLT device does not support access, and completes basic access operation through a preset standard optical network unit management control interface management entity, and a basic communication link has been established; the ONU is a civilian hundred-megabit model, and an interface capability set template includes: a downstream hundred-megabit rate, four service ports, a general optical network unit management control interface protocol version, and a maximum carrying bandwidth of 100 Mbps. The ONU gateway calls an interface capability set template of itself, performs fast data check operation on the template through a CRC algorithm, and generates a unique full-network check identifier: 256f9d7s8a6b5c4e3r2t1y. The ONU gateway sends the CRC identifier to the small non-standard OLT device through an optical network unit management control interface protocol. The OLT device quickly completes CRC verification, confirms that the interface capability information of the ONU is real and effective and matches the basic configuration of itself, and returns a confirmation instruction. After verification is completed by both parties, a standard optical network unit management control interface management connection is established.

[0056] In an embodiment, after the optical network unit management control interface management connection is established, a wavelength channel that is preset is configured as a backup channel, and the backup channel is used for disaster recovery backup and network capacity expansion.
