Description

Technical Field

[0001] The present invention relates to the technical field of dumb resource management, and more specifically, to a traceable coding method, a management method and an electronic device for ODN dumb resources. Background Art

[0002] An ODN (Optical Distribution Network) is an optical cable network based on PON (Passive Optical Network) devices. Its function is to establish an optical information transmission channel between an OLT (Optical Line Terminal) and a user (ONU, Optical Network Unit). It has passive physical characteristics and is difficult to control outdoors, so it is called a dumb resource.

[0003] The main difficulties in ODN dumb resource management mainly include: dumb resources cannot be monitored through network management, the network topology cannot be visually presented, there are characteristics such as difficult utilization of core fiber resources, difficult core fiber call, difficult expansion, difficult optical path quality operation and maintenance, and low troubleshooting efficiency. In order to improve the intelligence level of dumb resource management, the prior art records that by identifying the terminal distribution data and occupancy status in the as-built drawing and encoding each terminal based on this, the intelligent identification and digital processing of the dumb resources in the optical cross-connect box are realized. However, due to the large number of hierarchical levels of dumb resources in the optical distribution network, when the service coverage range of the optical distribution network is wide, a large number of ODN dumb resources will make the service logic complex. The above coding method cannot show the network topology of the dumb resources, it is difficult to provide detailed reference information for maintenance personnel, and it is also difficult to realize functions such as fast fault location, core fiber occupancy rate analysis, and fast query of dumb resource numbers. Summary of the Invention

[0004] The purpose of the present application is to provide a traceable coding method, a management method and an electronic device for ODN dumb resources. The present invention encodes the coding information of ODN dumb resources by combining the service area, convergence relationship and end grouping unit of the ODN, solves the problem that the coding information obtained by the current coding method cannot accurately draw the tree structure of the dumb resources. On the basis of this coding result, the ONU device is bound to the accessed DP box in the PON network management and resource management system, and then combined with the drawn tree structure, it can ensure that each ONU service can trace the dumb resource path it passes through, so as to effectively realize the refined management of the core fiber of the dumb resources, fault location and information loss query.

[0005] In the first aspect of the present invention, a traceable coding method for ODN dumb resources is provided, and the method includes:

[0006] Generating a first-level code according to the service area to which the ODN belongs;

[0018] In one implementation, if the DP - box is a box directly connected to the termination panel, the level number of the box - body level code is encoded as 1, and for each additional layer of serial DP - boxes, the value of the level number of the box - body level code is incremented by 1.

[0019] In one implementation, if the DP box is a box directly connected to an end plate and there is no upper DP box connected to it, the upper box base code is encoded as 0, otherwise the upper box base code of the current DP box is filled with the box number represented by the upper box's own base code.

[0034] Compared with the prior art, the present application has the following beneficial effects:

[0035] 1. The present invention establishes an association relationship between the PON network management and the optical path transmission path of dumb resources. Although dumb resources are passive devices and cannot be directly monitored on the PON network management, through the association relationship between the ONU device and the DP box and the traceable coding of the DP box, both the network management and the field can smoothly know the key path of service transmission (passing through the backbone optical cross-connect and community optical cross-connect that can converge the service). When a fault occurs in the ONU device, the PON network management extracts the data list interrupted by the ONU device, and forms a tree structure through the coding information of each dumb resource to judge the location interval of the fault; when the fault occurs in the non-critical node (service transparent optical cross-connect) path, the tree structure of the dumb resources is used to judge the fault location, solving the problem in the traditional technology that only the data list of the ONU device disconnection is known, but the fault level of the dumb resources is not clear, resulting in the inability to quickly recover the fault.

[0036] 2. The present invention improves the association relationship between the resource management system and the optical path transmission path of dumb resources. On the resource management system side, relying on the logical relationship of the tree topology structure of dumb resources, the error correction ability of the resource management system is improved, so that the incorrect entry of the optical path can be quickly identified, effectively improving the resource accuracy; on the field side, even if the box cover is lost on the site, or the spray code on the box cover is weathered and missing, and the dumb resource number cannot be known immediately, just find a customer or resource point under the dumb resource, and the lost dumb resource number can be found through the network management and the resource management system.

[0037] 3. The present invention strengthens the association relationship between the PON network management system and the resource management system. Currently, the PON network management system and the dumb resource management system operate independently, and their data can only be collected and analyzed through an intermediate system or manually. Due to the dispersion of the system data in the early stage and the lack of logical association relationships among the dumb resources, the information analysis ability is weak. After the tree structure of the dumb resources is drawn based on the coding information obtained by the coding method proposed in the present invention, first, the data accuracy of the dumb resource management system can be checked by comparing and verifying the data of the network management and resource management. Secondly, by checking the DP box numbers corresponding to the information of each ONU device on the network management side, the occupancy of the ports in the DP box can be counted. The effective utilization rate of the ports in the DP box can also be statistically calculated by using the off-net ONU device screening on the network management side, guiding the cleaning of the dormant fiber core resources in the DP box and releasing the ports still occupied by off-net customers. Thirdly, through the tree structure of the dumb resources, the fiber core occupancy can be calculated layer by layer, and the port utilization rate of each dumb resource point can be presented at any time, solving the problem that the previous dumb resources did not know the port occupancy situation and required prior investigation of the remaining fiber cores before use, resulting in difficult fiber core allocation. Finally, through the grouping of DP boxes achieved after coding, the spare fiber cores can be flexibly scheduled, and the remaining fiber cores of the DP boxes with lower utilization rates can be scheduled to the areas with business requirements, thereby improving the utilization rate of dormant dumb resources.

[0038] 4. Based on the coding information of the coded dumb resources, on both the resource management system side and the network management system side, the included relationship of the traceable coded dumb resources can be used for batch operations to statistically calculate the number of subordinate services of a certain dumb resource point and determine the service impact range of the dumb resource point, solving the problem of being unable to collect the number of subordinate services of dumb resources currently and reducing the maintenance difficulty.

[0039] 5. The present invention does not add new management systems and platforms, does not add resource management devices, and does not add electronic monitoring units on the dumb resource port side. Only need to draw the tree structure of the dumb resources according to the coding information obtained by coding, clean the dumb resources layer by layer from top to bottom using the tree structure, number the dumb resources, enter the dumb resource numbers into the resource management system, associate the numbers of the terminal dumb resources (DP boxes) with the ONU device information in the PON network management system, and complete the painting of the dumb resource numbers on-site to complete the management of the entire dumb resource coding.

[0040] 6. When troubleshooting or when the DP box needs to expand the ports of the secondary optical splitter, the maintenance personnel only need to stand by the roadside and check the number of the DP box, and then, through the logical inclusion relationship of the dumb resource numbers, they can know the number of the optical cross-connect box in the upper-level community. There is no need for the maintenance personnel to repeatedly climb the pole and perform high-altitude operations to repeatedly check and find the optical cross-connect box corresponding to the DP box, reducing the work difficulty and improving the work efficiency of the maintenance personnel.

The terms (such as those defined in a general use dictionary) will be interpreted as having the same meaning as the contextual meaning in the relevant technical field and will not be interpreted as having an idealized meaning or being overly formal unless clearly defined in the various embodiments of the present application.

[0052] To make the objectives, technical solutions, and advantages of the present application clearer and more understandable, the following further details the present application in conjunction with embodiments and the accompanying drawings. The illustrative embodiments of the present application and their descriptions are only for explaining the present application and do not serve as a limitation to the present application.

[0053] As Figure 1 shown, after the OLT data service emits light from the PON port, it will go through multiple optical path jump points, transmit the optical signal to the first-level optical splitter, equally divide the optical signal, then distribute it to the second-level optical splitter and perform secondary equal division of the optical signal, and finally reach the ONU device in the customer's room to complete the downlink transmission of the optical path; for the optical path uplink, it is transmitted through the reverse optical signal of the same optical cable core, and the ONU sends optical signals of different bands to travel retrograde along the original optical path to the OLT.

[0054] As Figure 2 shown, for the equipment provided by current major OLT manufacturers, the maximum optical path splitting ratio is 1:128, that is, a maximum of 128 ONU devices can be mounted on one PON port. However, considering the optical performance of the ONU for receiving and emitting light, the failure rate of the optical splitter product, and the normal attenuation of the optical path, the optical path splitting ratio is generally selected as 1:64, and a tree-shaped optical path topology structure with two-stage 1:8 splitting is adopted.

[0055] As Figure 3 shown, due to the extremely large number of ODN resources and their passive characteristics, it is impossible to implement resource monitoring. The intricate connection relationships among the dumb resources make it impossible to draw the networking topology of the dumb resources, resulting in an extremely complex ODN network.

[0056] The main difficulties in the management of ODN dumb resources mainly include: the dumb resources cannot be monitored through the network management, the networking topology cannot be intuitively presented, the three major information barriers of network management, resource management, and the field cannot be completely broken through, and there are characteristics such as difficult utilization of fiber core resources, difficult fiber core call, difficult optical path quality operation and maintenance, and low troubleshooting efficiency.

[0057] With the development of time and technology, technologies such as iODN technology, optical iris ODN technology, ODN3.0 technology, ODN label QR code and deep learning technology, and ODN management EPC electronic label technology have emerged. The introduction of relevant technologies is as follows:

[0058] 1. iODN technology solution: Its core idea is to add certain intelligent features to the network without changing the passive network characteristics of ODN. For example, the identification and management of fiber optic connections, intelligent fiber optic indication, intelligent splitter management, etc. At the same time, a field tool PDA is introduced into the solution. With the cooperation of the PDA, the ODN network and the resource management system are realized to communicate in real time through a wide area wireless network or a wired broadband network; through the USB interface, the PDA communicates with the iODN and provides temporary power for the iODN.

[0059] Technical defects: The PDA tool can only access one ODN dumb resource at a time, and only after the ODN is connected to the PDA, will the latest port situation be uploaded to the resource management system. When there is no PDA access, the resource management system still operates the ODN stock resources, and the purpose of breaking the information barrier is not achieved; secondly, this technology requires a large number of resource acquisition and monitoring units, with high costs, high failure rates, and electronic products need to overcome outdoor environments, as well as more difficult problems in later maintenance.

[0060] 2. Optical iris ODN technology solution: Its core idea is to add an optical signal receiving and transmitting and analysis and processing single board OAI based on optical iris on the OLT side, add an OSU device for combining and splitting the service signals of the optical iris signal and the PON single board in the OLT computer room, and replace the ordinary splitter on the ODN side with optical iris splitters FDT and FAT, so as to equalize the OLT service optical signal and the OAI monitoring optical signal. Through the differential modulation of the splitter micro-ring structure, the difference of the optical signals at the output ports is realized. Finally, combined with the coherent detection technology on the device side and the feature capture intelligent algorithm on the network management side, the traditional ODN is made to have an identifiable "optical ID", automatically restore the optical path topology on the network management, and online monitor the optical path quality.

[0061] Technical defects: An OSU device for combining and splitting the service wave and the monitoring wave is added on the OLT device side, which greatly increases the failure risk of the OLT data service, and also increases the pressure on the computer room space, supporting power supply, and air conditioning cooling in the OLT computer room; secondly, the equipment and special splitter units invested are huge and the cost is high; thirdly, the optical iris ODN only solves the structural topology of the optical path, and does not achieve the drawing of the structural topology of the resource tree, and is not synchronized with the resource management system; fourthly, for the FDT and FAT splitters, they need to carry service optical signals and monitoring optical signals in the outdoor environment, and there is doubt whether their sensitive optical components can be stably applied for a long time;

[0062] 3. ODN 3.0 Optical Network Quick Coverage Solution: Its main principle is to implement digital barcodes and QR codes for all optical cables, optical distribution boxes, DP boxes, optical splitters and interfaces, and enter the resources into the resource management system by scanning codes according to the resource association relationship to achieve accurate resource entry and solve the problem of dumb resources in ODN.

[0063] Technical deficiencies: First, digital barcodes and QR codes only synchronize the on-site port resources with the resource management system, but do not reach the synchronization of the network management system; second, after long-term erosion and weathering in the outdoor environment, the label recognition rate decreases, and even the labels fall off, which is likely to form a secondary information barrier; third, when maintenance personnel understand the resource information on-site, they still need to climb the pole to scan the code to know the specific service flow, which increases the maintenance difficulty and is not user-friendly to front-line workers.

[0064] 4. ODN Label QR Code and Deep Learning Solution: By introducing technologies such as label QR codes, GPS positioning, GIS map applications, and mobile Internet, through a professional network management system, unified and standardized maintenance and management of optical cable line resources, passive devices and ports, as well as service information and user information are carried out to achieve intelligent fiber management, establish and manage correct fiber connection relationships, provide effective guarantees for the security management, engineering construction, daily maintenance management and resource management of dumb resources, and improve the network operation and maintenance efficiency and security.

[0065] Technical deficiencies: In addition to the deficiencies of ODN 3.0, this technology also faces the problem that a large number of on-site resource ports have no labels, and basic data entry cannot be provided for them. It is necessary to comprehensively clean up the service link information with missing labels.

[0066] 5. ODN Management EPC Electronic Tag Solution: Its core idea is to add EPC level-1 electronic tags to the introduced optical cables and user optical cables at the ODN resource end to achieve the level-1 binding relationship between the optical cables and the optical distribution boxes and DP boxes; by adding EPC level-2 electronic tags to the household line optical cables, the level-2 binding relationship between the level-2 optical splitters and ONUs is achieved. Finally, the management system analyzes the level-1 and level-2 electronic tags to draw the network structure topology to achieve the purpose of ODN management.

[0067] Technical deficiencies: First, this solution requires adding electronic components on the ODN side, which increases a large number of redundant devices and units and has a high cost; second, ODN is a passive facility, and it is difficult to solve the power supply for EPC electronic tags and signal lights. Even if solar power is used, this solution labels each optical fiber with an electronic tag, and a large number of electronic components are difficult to reduce the failure rate during later maintenance, and the reliability will be greatly reduced; third, a large number of electronic components increase the pressure on later maintenance work and do not solve the problem of difficult traceability of on-site resources.

[0068] Through the above analysis, to solve the problem of dumb resource management, ensure the network is simple, efficient, and does not increase the risk of failures, be low-cost, be applicable to outdoor sites, and be friendly to front-line workers, this is the correct direction to solve the problem of ODN dumb resource management.

[0069] Therefore, to solve the technical deficiencies described above, an embodiment of the present invention provides a traceable coding method for ODN dumb resources. By drawing a dumb resource tree topology structure through coding information and binding the ONU device to the accessed DP box in the PON network management and resource management system, it can ensure that each ONU service can trace the key dumb resource path it passes through, effectively solve the problem of ODN dumb resource management, and realize functions such as fine management of fiber cores and fault location. Secondly, the present invention does not add new management systems and platforms, does not add new devices, and does not add new monitoring electronic components. Only need to clean the dumb resources layer by layer from top to bottom according to the dumb resource tree structure, number the resources, enter the dumb resource numbers into the asset management system, associate the numbers of the terminal dumb resources (DP boxes) with the ONU device information in the network management system, and complete the painting of the dumb resource numbers on-site to complete the transformation of the entire dumb resource management system, which is suitable for outdoor use. Finally, when dealing with faults or when the DP box needs to expand the secondary splitter ports, the maintenance personnel only need to stand by the roadside and view the number of the DP box, and then through the logical inclusion relationship of the dumb resource numbers, they can know the number information of the upper-level optical cross-connect or DP box, and no longer need the maintenance personnel to repeatedly climb the pole to check and find the optical cross-connect corresponding to the DP box, reducing the work difficulty and improving the work efficiency of the maintenance personnel.

[0070] Please refer to Figure 4 , Figure 4 is a schematic flowchart of a traceable coding method for ODN dumb resources provided by an embodiment of the present invention. As Figure 4 shown, the method includes

[0071] S401, generate a first-level code according to the business area to which the ODN belongs.

[0072] In this embodiment, the business area to which it belongs refers to different areas defined by the business area. For example, it can be defined to different areas such as provinces, cities, counties, and towns according to business needs. Secondly, as those skilled in the art can understand, the business area is composed of optical distribution networks.

[0073] For example, please refer to Figure 5, taking the "Dongpo" district of "Meishan" city as an example, according to the business area to which the ODN belongs, the first-level code is generated. At this time, the first-level code only includes the first identification code, thus realizing the encoding of the first-level code, denoted as ZDP. Among them, Z represents "Meishan" city, and DP represents "Dongpo" district. In terms of the character identification of the business area, it can be represented by the city code corresponding to each business area. For example, "Chengdu" city is A.

[0074] On this basis, the present embodiment further introduces the dummy resource type as a consideration, that is, the first-level code is generated according to the business area and the dummy resource type to which the ODN belongs. At this time, the first-level code includes the first identification code and the second identification code. It should be noted that the dummy resource attributes can be characterized into the following categories according to business requirements: dummy resource physical type, dummy resource jurisdiction scope level, dummy resource maintenance level, dummy resource business nature level, etc.; for the convenience of computer statistics, the second identification code dummy resource attributes can also be omitted to represent ordinary dummy resources, or the second identification code dummy resource attributes can be retained to represent special dummy resources.

[0075] At this time, assuming that the dummy resource is a backbone optical cross-connect and the business nature level is a government dedicated line, and assuming that the character P is used to represent the business nature level, then the encoded first-level code can be represented as ZDPP.

[0076] Based on the above description of the first-level code encoding, since a business area contains multiple dummy resource points and the area covered by the business area is not refined enough, a third identification code is introduced to represent the grid unit divided by the business area to which the ODN belongs, and its function is to further refine the business area. Exemplarily, assuming that the "Dongpo" district is divided into multiple grid units, if the number of a certain grid unit is 01, then the encoded first-level code can be represented as ZDPP01.

[0077] Since the encoding method provided by the embodiment of the present invention is for the encoding of dummy resources, and the dummy resources include backbone optical cross-connects, community optical cross-connects and DP boxes, therefore, in the first-level code, the dummy resource type can also be introduced for encoding. For example, the encoding representing the backbone optical cross-connect, assuming that the backbone optical cross-connect is represented by the character "GJ", that is, the first-level code encoding result is ZDPP01GJ.

[0078] Among the first-level codes, the first identification code is a letter, representing the service area; the second identification code is a letter, expressing the types, properties, grades, etc. included in the dummy resource attributes; the third identification code is a number, representing a more refined service area. For the convenience of identification and statistical operations, the first identification code + the second identification code + the third identification code can be used for representation, such as ZDPGJ01; if for the convenience of service area statistics, the first identification code + the third identification code can also be used to represent the specific service area, and the remaining parts are represented in segments, for example, ZDP01—GJ.

[0079] S402, generate a second-level code with key node numbers marked step by step from top to bottom according to the ODN convergence relationship.

[0080] In this embodiment, the front end of the dummy resource is connected to the communication machine room, and the rear end is connected to the ONU device. After the OLT data service in the communication machine room emits light from the PON port, it will go through multiple optical path jump points, transmit the optical signal to the first-level optical splitter, equally divide the optical signal, and then distribute it to the second-level optical splitter for secondary optical signal equal division, and finally reach the ONU device installed by the user to complete the optical path downlink transmission; for the optical path uplink, it is transmitted by reverse optical signal through the same optical cable core. The ONU device sends optical signals of different bands and travels back along the original optical path to the OLT device in the communication machine room.

[0081] It can be seen that in addition to converging the services within the corresponding area, each ODN dummy resource also has a relationship of parallel transparent transmission of services. That is, in addition to converging the community optical cross-connect services within the corresponding area, the backbone optical cross-connect can also connect to the next backbone optical cross-connect and has the function of transparently transmitting the optical path to the next backbone optical cross-connect; the same is true for the community optical cross-connect. In addition to converging multiple groups of DP boxes within the corresponding area, it can also connect to the next community optical cross-connect and has the function of transparently transmitting the optical path to the next community optical cross-connect; the same is true for the DP box. In addition to converging the ONU devices within the corresponding area, it also has the function of transparently transmitting the optical path to the next DP box. Here, we just need to change our thinking and use the DP box body level within the group to express the serial and parallel relationships between the boxes.

[0082] Therefore, in this embodiment, according to the ODN convergence relationship, a second-level code with key node numbers marked step by step from top to bottom is generated to realize the coding of the backbone optical cross-connect and the community optical cross-connect of the dummy resources, that is, the second-level code.

[0083] Since in the actual scenario, there are extreme application scenarios. For example, a backbone optical cross-connect is directly pulled out from the communication machine room and directly connected to the DP box, without involving dummy resources such as community optical cross-connects. Therefore, the second-level code encoded in this embodiment contains at least one key node identification code. Here, the meaning of the key node is the dummy resource, such as the backbone optical cross-connect and / or the community optical cross-connect, but does not include the DP box.

[0084] Therefore, in this embodiment, the key node identification code refers to the sequential numbering of optical cross-connects with a convergence relationship.

[0085] Specifically, the optical cable network of the ODN (Optical Distribution Network) is an optical information transmission channel established between the OLT device and the ONU device. The ODN dumb resource points are the key nodes of the resources carrying the optical information transmission channel. Because the optical information channel between the OLT and the ONU has a long transmission distance and not all the dumb resource points are connected to the computer room, when building the optical information channel, the dumb resource points will be used to jump the fiber to the corresponding service convergence area. When only using the dumb resource points to jump the fiber without using their service aggregation function, it belongs to the transparent transmission of the optical signal service of the dumb resource points; when the optical signal reaches the service convergence area and reaches the next-level (or more specific) service area through the service aggregation relationship of the dumb resource points, it is the service aggregation of all the optical signals hanging under the dumb resource points. Therefore, in order to more accurately express the structural association relationship of the dumb resource tree, the dumb resources of the service transparent transmission type should be ignored, and only the dumb resources of the service aggregation should be expressed.

[0086] The optical cross-connects can be divided into backbone optical cross-connects, community optical cross-connects, and building optical cross-connects. However, considering that the first-level optical splitter is placed in the last key node, for simplicity of representation, the situation where the building optical cross-connect, which is the third key node code, is included in the second-level code will not be specifically described. Therefore, in this embodiment, the convergence relationship between the two key nodes of the backbone optical cross-connect and the community optical cross-connect is mainly described. For example, if community optical cross-connect 01 and community optical cross-connect 02 are tapped from backbone optical cross-connect 01 hanging under the communication computer room, then backbone optical cross-connect 01 forms a convergence relationship with community optical cross-connect 01 and community optical cross-connect 02 respectively. In other words, community optical cross-connect 01 and community optical cross-connect 02 are branches of backbone optical cross-connect 01. When the dumb resource points contain backbone optical cross-connects, community optical cross-connects, and building optical cross-connects, the principle of their convergence relationship is the same, and this embodiment will not repeat the description. Therefore, in this embodiment, the key node identification code can be divided into Figure 5 the first key node identification code and the second key node identification code according to the content shown in the schematic. If the building optical cross-connect is also included in a communication scenario, then the key node identification code can also be divided into the third key node identification code.

[0087] For example, Figure 5 taking backbone optical cross-connect 01 pulled out from grid unit 01 as an example, and assuming that two community optical cross-connects are pulled out on the basis of backbone optical cross-connect 01, which are respectively coded as community optical cross-connect 01 and community optical cross-connect 02. Thus, for the second-level code, its numbers are 0101 and 0102, which means that both community optical cross-connect 01 and community optical cross-connect 02 are branches of backbone optical cross-connect 01.

[0088] In some embodiments, if a key node in the second - level code is missing or unused, character filling is performed on the key - node identification code corresponding to the key node. The optical cross - connect includes a backbone optical cross - connect and a cell optical cross - connect.

[0089] Specifically, the situation where a key node in the second - level code is missing or unused is divided into the following two cases:

[0090] If the backbone optical cross - connect is directly connected to a DP box below, it means that the cell optical cross - connect representing the optical - path transmission path of the dumb resource is missing. Character filling is performed on the key - node identification code corresponding to the cell optical cross - connect in the second - level code;

[0091] If the cell optical cross - connect is directly connected to the machine room, it means that the backbone optical cross - connect representing the optical - path transmission path of the dumb resource is missing. Character filling is performed on the key - node identification code corresponding to the backbone optical cross - connect in the second - level code.

[0092] If the DP box is directly connected to the machine room, it means that the backbone optical cross - connect and the cell optical cross - connect representing the optical - path transmission path of the dumb resource are missing. Character filling is performed on the key - node identification codes corresponding to the backbone optical cross - connect and the cell optical cross - connect in the second - level code.

[0093] Specifically, in an actual dumb - resource communication scenario, there are scenarios where the backbone optical cross - connect and the cell optical cross - connect are missing or unused. For example, as described above, a backbone optical cross - connect 01 is directly pulled out from the communication machine room and directly connected to the DP box. In this case, the cell optical cross - connect is unused. That is, the backbone optical cross - connect is encoded as a key - node identification code, and the cell optical cross - connect is encoded as a key - node identification code. The two key - node identification codes are arranged in order. Therefore, the second - level code in this dumb - resource communication scenario can be encoded as 0100, where 00 is the filled character. As those skilled in the art can understand, 01, 00, etc. shown in this embodiment are all implementation means of filling, and those skilled in the art can replace them with other characters, such as English characters.

[0094] In this embodiment, there may also be an actual scenario where a cell optical cross - connect 01 is directly connected to the communication machine room and its upper - level is not connected to the backbone optical cross - connect. Then, for the second - level code, the key node of the backbone optical cross - connect is missing or unused. Therefore, character filling is performed on the key - node identification code of the backbone optical cross - connect in the second - level code, that is, 0001.

[0095] In this embodiment, there may also be an actual scenario where a DP box is directly connected to the communication machine room and its upper - level is not connected to the backbone optical cross - connect. Then, for the second - level code, the key nodes of the backbone optical cross - connect and the cell optical cross - connect are missing or unused. Therefore, character filling is performed on the key - node identification codes of the backbone optical cross - connect and the cell optical cross - connect in the second - level code, that is, 0000.

[0096] It should be noted that the identification code described in the above steps S401 and S402 can be encoded according to the preset character positions, and the unused character positions can be filled with 00. In addition, the above identification code can also be composed of an identifier and an identifier. The identifier is mainly used to split the coded information into multiple identification codes, and the identifier is mainly the number information representing the device.

[0097] Based on this, the association relationship between the dumb resource points can be obtained from the coding information of the second-level code, such as the convergence relationship between the trunk optical switch and the cell optical switch, so as to improve the association degree of dumb resource management.

[0098] S403: Generate a third level code including a grouping number and a traceable code of a node in the group according to the ODN terminal grouping unit.

[0099] In this embodiment, the ODN terminal grouping unit refers to the DP box hanging under the main optical exchange / cell optical exchange, or the DP box hanging under the communication room. Specifically, for a cell or park, this embodiment uses the terminal disk of the main optical exchange / cell optical exchange to determine the grouping code to which the DP box belongs. For example, if there are four terminal disks, the DP box grouping code provided by this embodiment can be determined, such as 01, 02, 03 and 04. That is, the DP box grouping code is configured as follows: grouping the DP boxes hanging under the terminal disk configured by the trunk optical exchange / cell optical exchange, and creating intra-group nodes for the DP box traceable coding;

[0100] The DP box in each group also has multiple DP boxes hanging below it, and the layers, superiors and the DP boxes to which they belong are coded, that is, the DP box traceability code is determined. That is, the DP box traceability code is configured as follows: logical coding is performed according to the order in which the DP boxes are connected to the terminal disks and the serial and parallel relationship between the DP boxes.

[0101] The traceability code of the DP box includes the box level code, the upper-level box base code and the self-base code; wherein, the box level code represents the level number to which the DP box in the group belongs, the upper-level box base code represents the self-base code of the upper-level DP box to which the current box belongs, and the self-base code represents the box number in this level or this group.

[0102] Specifically, with respect to the cabinet level code, in some embodiments, if the DP box is a cabinet directly connected to an end tray, the level number of the cabinet level code is encoded as 1, and the value of the level number of the cabinet level code is increased by 1 for each additional layer of serial DP box.

[0103] Specifically, assume that all the DP boxes hung under the termination panel 02 of the community optical cross-connect 01 are in one grouping number, that is, the box body grouping code is 02. On this basis, the box body level code is determined by the serial level where the independent DP box hung under the termination panel is located. For example, if 4 DP boxes are serially connected under the community optical cross-connect 01, then the box body level code can be encoded as the corresponding box body serial level. For example, it is encoded with numbers 01 - 04 to obtain the encoding information of 01021, 01022, 01023, and 01024.

[0104] Specifically, due to the serial connection relationship between DP boxes, in this embodiment, the superior box body standard code is introduced to represent the serial connection relationship of each DP box. Assume that there are 2 layers of DP boxes hung under the termination end 02 of a community optical cross-connect 01, and each layer contains 3 DP boxes. For example, the DP box bodies in the first layer are numbered 1, 2, and 3 respectively, which are the box body self-standard codes proposed in this embodiment. Based on DP box 1, DP box 2, and DP box 3, DP box 1 hangs under DP box 4, DP box 2 hangs under DP box 5, and DP box 3 hangs under DP box 6. Then, for DP box 4, the box body level code it belongs to is 2, that is, encoded as 2, the superior box body standard code is DP box 1, encoded as 1, and the box body self-standard code is 4, encoded as 4. Then, the encoding information result of the third level code of DP box 4 is 02214, and the encoding information result of the third level code of DP box 6 is 02236.

[0105] The above embodiments discuss the communication scenario where there is a termination panel configured in the optical cross-connect and DP boxes are hung under it, and there are serially connected DP boxes above the DP boxes. There is also the following communication scenario: If the DP box is a box directly connected to the termination panel and there is no connected DP box above it, then the superior box body standard code is encoded as 0; otherwise, the superior box body standard code of the current DP box is filled with the box number represented by the self-standard code of the upper-level box body.

[0106] In this embodiment, for example, the termination panel 01 of the community optical cross-connect 01 is only connected in parallel to three DP boxes, which are encoded as DP box 1, DP box 2, and DP box 3 respectively. Correspondingly, because it is a parallel connection, the box body level code is encoded as 1. Then, for DP box 1, DP box 2, and DP box 3, the one they are connected to above is the termination panel 01 of the community optical cross-connect 01, and there is no connected DP box. It should be noted here that for DP box 1, DP box 2, and DP box 3, they have no superior box body standard code. Therefore, when encoding, the superior box body standard code is encoded as 0. Thus, for DP box body 1, its third level code is encoded as 01101, for DP box body 2, its third level code is encoded as 01102, and for DP box body 3, its third level code is encoded as 01103.

[0107] It should be noted that when both the backbone optical cross-connect and the community optical cross-connect described in the above embodiments are missing or unused, all the critical node identification codes in the second-level code will be missing or unused. For example, if an important communication service reaches the destination directly through an optical cable from the communication machine room, the coding method can be selected according to the service requirements. For example: ZDPX000001101, which represents the No. 1 DP box of the No. 1 group of X-type services in Dongpo District, Meishan City.

[0108] As the end resource point of the dumb resources, the number of DP boxes is huge and the resource structure is unclear, resulting in the difficult management of dumb resources. Therefore, the focus of the present invention is to group the DP boxes, realize the traceable coding of the DP boxes within the group, and then combine the association relationship of the backbone optical cross-connect and the community optical cross-connect, and the covering relationship of the service area, so as to realize the coding of the entire dumb resources.

[0109] For the third-level code proposed in this embodiment, when troubleshooting or when the DP box needs to expand the second-level splitter port, the operation and maintenance personnel only need to stand by the roadside and check the number of the DP box, and then they can know the number information of the upper-level optical cross-connect or the DP box body through the logical inclusion relationship of the dumb resource number, without the need for the maintenance personnel to repeatedly climb the pole to check and find the corresponding community optical cross-connect or the upper-level DP box of the DP box, which reduces the work difficulty and improves the work efficiency of the operation and maintenance personnel.

[0110] S404, combine the first-level code, the second-level code and the third-level code in sequence to obtain the coding information of the ODN dumb resources.

[0111] In this embodiment, combine the coding results of the first-level code, the second-level code and the third-level code described in the above embodiments in sequence. For example, in the second-level code, if the critical node is not passed, that is, character filling is performed on the second-level code, and the filling result can be 0000. Then the coding information of the ODN dumb resources after combining the first-level code and the third-level code is ZDPX01000001101. If it is a special service, for example, direct connection from the communication machine room to the destination with an optical cable is required, the second-level code characters can also be omitted, and the combined coding information of the ODN dumb resources is ZDPX0101101.

[0112] Such as Figure 5 As shown, the expression example of the coding rule (for the convenience of computer statistics, the second identification code dumb resource attribute is omitted in this example) is described as follows:

[0113] A. Backbone optical cross-connect: ZDP + 01 + 01 (Dongpo District, Meishan City + grid unit number + backbone optical cross-connect number);

[0114] B. Community optical cross-connect: ZDP + 01 + 01 + 01 (Dongpo District, Meishan City + grid unit number + backbone optical cross-connect number + subordinated community optical cross-connect number);

[0115] C. DP box: ZDP+01+01+01+01+101 (Dongpo District, Meishan City+grid unit number+trunk optical exchange number+downlinked community optical exchange number+corresponding community optical exchange internal terminal disk number+three-digit traceability number).

[0116] like Figure 6 As shown in the figure, it is a schematic diagram of DP box series parallel connection. The device coding of each DP box is as follows:

[0117] A. DP box 1 number: ZDP010101+01(end tray number)+1(primary box directly connected to optical crossover)+0(upper level box number)+1(this box number);

[0118] B. DP box 4 number: ZDP010101+01(end tray number)+1(primary box directly connected to optical crossover)+0(upper level box number)+4(primary box number);

[0119] C. DP box 2 number: ZDP010101+01(end tray number)+2(secondary box)+1(upper level box number)+2(main box number);

[0120] D. DP box 5 number: ZDP010101+01(end tray number)+2(secondary box)+1(upper level box number)+5(basic box number);

[0121] E. DP box 3 number: ZDP010101+01(end tray number)+3(third-level box)+2(upper level box number)+3(basic box number);

[0122] F. DP box 6 number: ZDP010101+01(end tray number)+3(third-level box)+5(upper level box number)+6(basic box number);

[0123] G. DP box 7 number: ZDP010101+01(end tray number)+3(third-level box)+2(upper level box number)+7(basic box number);

[0124] H. DP box 8 numbering: ZDP010101+01(end tray number)+4(fourth-level box)+3(upper level box number)+8(primary box number).

[0125] According to the coding information generated in this embodiment, combined with the technical means of drawing the tree structure, a tree structure about dumb resources can be drawn. Usually, the trunk optical exchange represents the root key node of the tree structure, the cell optical exchange and the DP box represent the sub-key nodes of the tree structure, a grid unit contains several tree structures, and a service area contains several grid units, ultimately realizing the traceable coding of dumb resources in the entire network.

[0126] It can be seen that the present invention solves the problem of incomplete information of dumb resources in actual scenarios by performing traceable coding on the DP box, breaking the information barrier between dumb resources. Even if the box cover is lost, as long as the installation and maintenance personnel find the mobile user in the vicinity and view the ONU information of the user, they can find the device code of the damaged DP box, and thus smoothly find the upper-level port. Moreover, through the device code of the DP box, the key routes (main optical cross-connect, community optical cross-connect) passed by its service path can be directly distinguished, the service logic is stronger, and the ability of asset management to correct errors is significantly improved.

[0127] The embodiment of the present invention also provides a method for managing ODN dumb resources. The method includes: obtaining the interruption data of the ONU device and the coding information generated based on a traceable coding method for ODN dumb resources described in the above embodiments; wherein, the interruption data refers to the fault alarm information implemented by the PON network management for the ONU device; generating a tree structure of the ODN dumb resources according to the coding information, and inferring the faulty ODN dumb resources in combination with the interruption data and the tree structure.

[0128] As Figure 7 shown, Figure 7 is a schematic diagram of the fault influence range provided by the embodiment of the present invention. The embodiment of the present invention establishes an association relationship between the PON network management and the optical path transmission path of the dumb resources. Although the dumb resources are passive devices and cannot be directly monitored on the PON network management, through the association relationship between the ONU device and the DP box and the traceable coding of the DP box, both the network management and the field can smoothly know the key path of service transmission (passing through the main optical cross-connect and community optical cross-connect that can converge the service). When a fault occurs in the ONU device, the PON network management extracts the data list of the interruption of the ONU device, and forms a tree structure through the coding information of each dumb resource to judge the location interval of the fault. When the fault occurs on the path of non-critical nodes (service transparent optical cross-connect), the tree structure of the dumb resources is used to judge the fault location, solving the problem in the traditional technology that only the data list of the ONU device disconnection is known, but the fault level of the dumb resources is not clear, resulting in the inability to quickly recover the fault.

[0129] The embodiment of the present invention also provides a method for managing ODN dumb resources. The method includes: obtaining the occupied data of the outgoing optical ports of each DP box and the coding information generated based on a traceable coding method for ODN dumb resources described in the above embodiments; generating a tree structure of the ODN dumb resources according to the coding information, and determining the core utilization rate of each node of the ODN dumb resources in combination with the occupied data of the outgoing optical ports and the tree structure.

[0130] It can be seen that the embodiments of the present invention strengthen the association relationship between the PON network management and the resource management system. Currently, the PON network management system and the dumb resource management system operate independently, and their data can only be collected and analyzed through an intermediate system or manually. Due to the dispersion of the system data in the early stage and the lack of logical association relationships among the dumb resources, the information analysis ability is weak. After the tree structure of the dumb resources is drawn based on the coding information obtained by the coding method proposed in the present invention, first, the data accuracy of the dumb resource management system can be checked by comparing and verifying the data of the network management and the resource management. Secondly, by checking the DP box numbers corresponding to the information of each ONU device on the network management side, the occupancy of the ports in the DP box can be counted, and the situation of off-net ONU devices can be screened on the network management side to count the effective utilization rate of the ports in the DP box, so as to guide the cleaning of the dormant fiber core resources in the DP box and release the ports still occupied by off-net customers. Thirdly, through the tree structure of the dumb resources, the fiber core occupancy can be calculated layer by layer, and the port utilization rate of each dumb resource point can be presented at any time, solving the problem that the previous dumb resources did not know the port occupancy situation and it was necessary to first investigate the remaining fiber cores before use, resulting in difficult fiber core call. Finally, through the grouping of DP boxes realized after coding, the spare fiber cores can be flexibly scheduled, and the remaining fiber cores of the DP boxes with low utilization rate can be scheduled to the business demand area, thereby improving the utilization rate of dormant dumb resources.

[0131] The embodiments of the present invention also provide a method for managing ODN dumb resources, and the method includes: obtaining the ONU devices or dumb resource points under which the ODN dumb resources with lost dumb resource number information are hung, and the coding information generated based on a traceable coding method for ODN dumb resources provided in the first aspect of the present invention; generating a tree structure of the ODN dumb resources according to the coding information, and querying the number information of the ODN dumb resources from the tree structure in combination with the ONU devices or dumb resource points.

[0132] Specifically, the embodiments of the present invention improve the association relationship between the resource management system and the optical path transmission path of the dumb resources. On the resource management system side, relying on the logical relationship of the tree topology structure of the dumb resources, the error correction ability of the resource management system is improved, so that the errors in the optical path entry can be promptly identified and distinguished, effectively improving the resource accuracy rate; on the site side, even if the box cover is lost on the site or the spray code on the box cover is weathered and missing, and it is impossible to know the dumb resource number immediately, just find a customer or resource point under which the dumb resource is hung, and the lost dumb resource number can be found through the network management and the resource management system.
