Description

Technical Field

[0001] The invention belongs to the field of optical fiber communication networks, and in particular relates to a method for performing network upgrade planning 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, it still faces many challenges in the implementation process of planning, design and management. For example, in the planning and design stage of the optical fiber access network, communication operators still rely mainly on manual drawing and the experience of professionals, and in the management stage of the optical fiber access network, they still rely mainly on traditional manual monitoring tools and manual analysis; such manpower-dominated methods lack the support of digital tools, which, on the one hand, makes the implementation process of the planning, design and management stages lack automation, and on the other hand, makes the information about each stage of the optical fiber access network life cycle scattered in different systems, forming independent "data islands". This makes the implementation process of the planning, design and management of the optical fiber access network time-consuming and complicated, and prone to human errors, which reduces efficiency. In particular, for network upgrade planning, relying on traditional manual analysis and planning is prone to low accuracy and low efficiency; how to accurately and efficiently carry out network upgrade planning without relying on the experience of professionals is an urgent problem to be solved. Therefore, in response to the above problems, this technical solution proposes a method for network upgrade planning based on a hierarchical model. Summary of the invention

[0004] The present invention provides a method for network upgrade planning based on a hierarchical model. This solution fully combines the full life cycle management of the optical fiber access network and systematically coordinates various factors. It can efficiently and accurately realize rapid network upgrade planning without relying on the experience of professionals, greatly improving the efficiency of network upgrade planning and helping to reduce operation and maintenance costs. 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 network upgrade planning based on a hierarchical model of the present invention is managed based on a full life cycle management system of an optical fiber access network;

[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;

[0008] The method for network upgrade planning based on the data defined by the hierarchical model includes the following steps:

[0009] S1, taking the life cycle data of the optical fiber access network in the operation phase as input;

[0010] S2, extracting each optical fiber access network node currently managed by the optical fiber access network full life cycle management system from the optical fiber access network life cycle data;

[0011] S3. According to the identification of each node, the available resources of each fiber access network node are indexed in the node status database and obtained;

[0012] S4. Upgrade the equipment in the relevant cables and optical fiber access network nodes as needed according to future development plans;

[0013] S5. Output the additional equipment and cables required for network upgrade.

[0014] Furthermore, the fiber optic access network life cycle management system creates fiber optic access network life cycle data in the planning stage; then, the fiber optic access network life cycle data is initialized and filled in the planning stage; the initialization filling is specifically: the fiber optic access network life cycle management system determines the location of the fiber optic access network in the planning stage, and divides the coverage area of ​​the fiber optic access network; and, in this stage, the required fiber optic access network nodes, the locations of the nodes, and the topological relationships between the nodes are planned.

[0015] Furthermore, the optical fiber access network full life cycle management system maintains optical fiber access network life cycle data during the operation phase, specifically including operation status information of the optical fiber access network monitored by the system during the operation phase.

[0016] 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.

[0017] 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.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] (1) This solution fully combines the full life cycle management of the optical access network and systematically coordinates various elements. It can efficiently and accurately implement rapid network upgrade planning without relying on the experience of professionals, greatly improving the efficiency of network upgrade planning and helping to reduce operation and maintenance costs;
