Description

Technical Field

[0001] The present invention belongs to the field of optical fiber communication networks, and in particular relates to a full life cycle management method for an optical fiber access network based on a hierarchical model. Background Art

[0002] Optical access network, referred to as OAN, is a communication network based on optical fiber communication technology that connects the backbone network to the end user. Compared with the traditional copper cable access method, the optical access network provides higher bandwidth, lower latency and more stable services. With the increasing demand for high-speed broadband access, optical access network has gradually become the mainstream implementation method of modern broadband access.

[0003] Although the optical fiber access network has significant technical advantages, its implementation process in the planning, design and management stages still faces many challenges. For example, US20230342506 discloses the construction of an integrated waveguide system design tool for guiding the design, ordering and providing manufacturing and installation instructions of the waveguide system network. The scheme includes optical fiber network design data, which includes data of different optical fiber types, data of different optical fiber cable quantities and cost data of different optical fiber network topologies; the user report module is connected to the network analysis module, and according to the calculated optical fiber network design data, at least one optical fiber network design report is sent to the user through the global computer network. The above-mentioned prior art has the following disadvantages: the prior art only summarizes the functional modules included in the system for planning and designing optical fiber access networks, but does not explain which elements should be coordinated and how to coordinate these elements in the context of the full life cycle management of optical fiber access networks; on the one hand, this makes it difficult for the system developed based on this to quickly meet the various needs of the full life cycle of the optical fiber access network, limiting the applicability of the system; on the other hand, this makes it difficult for developers to effectively integrate various elements into a comprehensive system, reducing development efficiency and system scalability. Therefore, in response to the above problems, this technical solution proposes a method for full life cycle management of optical fiber access networks based on a hierarchical model. Summary of the invention

[0004] The present invention provides a method for managing the entire life cycle of an optical fiber access network based on a hierarchical model. The system design based on the hierarchical model can cover all stages of the entire life cycle of the optical fiber access network, ensure that the developed management system uses consistent management interfaces and tools in each stage, enhance data sharing and collaboration efficiency between stages, and thus reduce the time and cost of network design, deployment, and management; the solution solves the problem that the existing development solution of the entire life cycle management system of the optical fiber access network still remains at the local level of developing specific functional modules for a certain stage, and cannot fully combine the needs of the entire life cycle management of the optical fiber access network and systematically coordinate various elements to support the efficient development of the system; in summary, the problems in the background technology are solved.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] The method for managing the entire life cycle of an optical fiber access network based on a hierarchical model of the present invention is managed based on the optical fiber access network entire life cycle management system;

[0007] The optical fiber access network full life cycle management system receives domain knowledge from engineering practitioners and obtains digital definitions in a hierarchical model, and then classifies and integrates it into the corresponding levels of the system; the hierarchical model includes a system function layer, an entity component layer, a composite structure layer, a space attribute layer and a database; the system function layer is used to divide complex business logic into various functional modules that serve the optical fiber access network life cycle management; the entity component layer is used to define the content of each entity component involved in the full life cycle of the optical fiber access network; the composite structure layer aggregates independent entity components into a composite structure based on specific relationships, and the composite structure is aggregated by entity components; the spatial attribute layer defines various spatial attributes that characterize entities and structures; the database is used to integrate external data to provide necessary information support for the management of the full life cycle of the optical fiber access network;

[0014] S2. Based on the description of the functional contents of each system in a hierarchical model, the system functions are realized with the support of the optical fiber access network life cycle data at each stage;

[0015] The system functions are implemented including obtaining the consumption of equipment and cables required for network construction based on the fiber optic access network life cycle data during the implementation of the material cost analysis function, and obtaining the corresponding unit material cost by querying the equipment database and cable database, thereby completing the material cost analysis.

[0016] Furthermore, the system creates optical fiber access network life cycle data in the planning stage; then, the system initializes and populates the optical fiber access network life cycle data in the planning stage.

[0017] Furthermore, the initialization filling specifically includes: the system determines the location of the fiber optic access network and divides the coverage area of ​​the fiber optic access network during the planning stage; and the system plans the fiber optic access network nodes, node locations and topological relationships between nodes required at this stage.

[0018] Furthermore, the system refines the fiber optic access network lifecycle data during the design phase; specifically, the system determines the equipment required to be included in each fiber optic access network node during the design phase, and determines the cables connecting the nodes and the specific wiring paths of the cables.

[0019] Furthermore, the system updates the fiber optic access network lifecycle data during the deployment phase, specifically updating the data of the devices included in the fiber optic access network nodes, the cables connecting the nodes, and the wiring paths of the cables according to the actual deployment of the fiber optic access network.

[0020] Furthermore, the system maintains the optical fiber access network life cycle data during the operation phase, specifically including the operation status information of the optical fiber access network monitored by the system during the operation phase.

[0021] Furthermore, the operation status information includes optical power, bit error rate, load condition and network delay information of a specific optical fiber access network node, and data describing the node status in the system is continuously maintained based on this.

[0022] Furthermore, the data describing the node status is provided for analysis by the operation and maintenance team, and potential faults including fiber attenuation, load or delay are promptly identified and checked to ensure stable operation of the network.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] (1) This solution is based on a hierarchical model system design that can cover all stages of the fiber access network life cycle, ensuring that the management system developed uses consistent management interfaces and tools at all stages, enhancing data sharing and collaboration efficiency between stages, and thus reducing the time and cost of network design, deployment, and management;

[0025] (2) This solution solves the problem that the existing optical fiber access technology is still stuck at the local level of developing specific functional modules at a certain stage, and cannot fully integrate the full life cycle management of the optical fiber access network and systematically coordinate various elements to support the efficient development of the system;

In the management stage of optical fiber access networks, efficient management can be achieved without relying on traditional manual monitoring tools and manual analysis;

[0027] (4) This solution ensures that the fiber access network life cycle management system developed and upgraded based on this solution can quickly adapt to changes in technology and demand, and demonstrates high scalability by consistently organizing the newly added domain knowledge at all levels of the model.
