Description

Technical Field

[0001] The invention belongs to the field of optical fiber communication networks, and in particular relates to a data realization system and 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 fiber optic access network has significant technical advantages, its implementation process in the planning, design and management stages still faces many challenges. For example, in the planning and design stage of the fiber optic access network, communication operators still rely mainly on manual drawing and the experience of professionals, and in the management stage of the fiber optic access network, they still rely mainly on traditional manual monitoring tools and manual analysis; this kind of manpower-dominated method lacks the support of digital tools. On the one hand, it makes the implementation process of the planning, design and management stages lack automation, and on the other hand, it also makes the information about the various stages of the fiber optic access network life cycle scattered in different systems, forming independent "data islands". This makes the implementation process of the planning, design and management stages of the fiber optic access network time-consuming and complicated, and is prone to human errors, which reduces efficiency. Therefore, this technical solution proposes a data implementation system and method for the fiber optic access network based on a hierarchical model. Summary of the invention

[0004] The present invention provides a data implementation system and method for a fiber optic access network based on a hierarchical model. The hierarchical model is used as the core of system development. By integrating knowledge in related fields layer by layer, the efficient and easily expandable development of an implementation system covering the planning, design, deployment and operation stages of the fiber optic access network is supported. In summary, the problems in the background technology are solved.

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

[0006] The data realization system of the optical fiber access network based on the hierarchical model of the present invention receives the domain knowledge from the engineering practitioners and obtains the digital definition in the hierarchical model, and then classifies and integrates it into the corresponding layers of the system;

[0007] The hierarchical model is used to describe the functions that system developers need to implement and provide digital definitions of the objects involved in the functions, thereby providing a design basis for the implementation of the functions; the hierarchical model includes a system function layer, an entity component layer, a composite structure layer, a space attribute layer and a database;

[0008] The system function layer is used to divide the complex business logic into various functional modules serving the life cycle management of the optical fiber access network;

[0009] The entity component layer is used to define the content of each entity component involved in the entire life cycle of the optical fiber access network;

[0010] The composite structure layer aggregates independent entity components into a composite structure based on a specific relationship, and the composite structure is formed by the aggregation of entity components;

[0011] The spatial attribute layer defines various spatial attributes that characterize entities and structures;

[0012] The database is used to integrate external data and provide necessary information support for the management of the entire life cycle of the optical fiber access network;

[0013] In the hierarchical model, system functions act on composite structures and entity components that belong to the same management object, and specific functions are achieved by manipulating and calculating the composite structures and entity components; the management object has spatial attributes.

[0014] Furthermore, the system function layer, entity component layer, composite structure layer, space attribute layer and database are relatively independent of each other, and domain knowledge added or modified in one layer only affects this layer without interfering with other layers.

[0015] Furthermore, the hierarchical model can continuously receive new domain knowledge and adjust and expand the content of each layer, thereby providing basic support for the continuous optimization and iteration of the system.

[0016] The data realization method for optical fiber access network based on hierarchical model is used to realize the data realization system for optical fiber access network based on hierarchical model, and comprises the following steps:

[0017] S1. Based on the hierarchical model, the data content and form are defined. The optical access network life cycle data is created in the planning stage, refined in the design stage, updated in the deployment stage, and maintained in the operation stage.

[0018] 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 fiber access network life cycle data at each stage.

[0019] Furthermore, the optical fiber access network life cycle data includes generating an initial distribution of optical fiber access network nodes to obtain an information framework of the optical fiber access network life cycle data.

[0020] Furthermore, the refinement during the design phase includes adding more specific network topology details, node parameters, and cable types, so that the data is gradually refined to be deployable.

[0021] Furthermore, the updating during the deployment phase includes adjusting and supplementing information such as actual laying paths, equipment installation locations, etc. according to actual deployment conditions, so as to ensure that the data accurately reflects the physical implementation of the network.

[0022] Furthermore, the maintenance during the operation phase includes continuous monitoring of network operation to continuously calibrate and optimize data content.

[0023] Furthermore, the system function is realized including in the process of realizing the material cost analysis function, based on the fiber optic access network life cycle data, obtaining the consumption of equipment and cables required for building the network, and obtaining the corresponding unit cost of materials by querying the equipment database and cable database, and then completing the material cost analysis.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] (1) 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;

[0026] (2) This solution takes the hierarchical model as the core of system development. By integrating knowledge in related fields layer by layer, it supports the efficient and easy-to-expand development of the implementation system covering the stages of optical access network planning, design, deployment and operation, which can reduce human errors and greatly improve efficiency.

[0027] (3) This solution systematically organizes and structures the domain knowledge of engineering practitioners from top to bottom, and uses it to guide software developers to develop a system for the full life cycle management of optical fiber access networks, without relying on manual drawings and the experience of professionals. In the management stage of optical fiber access networks, efficient management can be achieved without relying on traditional manual monitoring tools and manual analysis;

[0028] (4) This solution ensures that the optical fiber access network life cycle management system developed and upgraded based on this solution can quickly adapt to changes in technology and requirements, and demonstrates high scalability by consistently organizing the newly added domain knowledge at all levels of the model;

[0029] (5) The system function layer, entity component layer, composite structure layer, spatial attribute layer, and database are relatively independent. Domain knowledge added or modified in one layer only affects that layer without interfering with other layers, which is highly efficient.

[0030] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
