[0002] With the promotion of digital construction and the increase of 5G network construction, the communication business volume of transmission network increases rapidly, and a large number of new node machine rooms and new optical exchange boxes and other transmission resources are put into use. However, when the transmission pipeline bearing reaches a bottleneck, a large number of transmission pipelines appear to have too high load, which introduces major network security risks. Once a fault occurs, it will cause great loss. In addition, in the traditional dumb resource planning and project management work, there are phenomena such as insufficient digital capability, lack of intelligent means, and low online degree, which leads to insufficient scientific planning ability of the pipeline, increased burden on network planning and operation and maintenance personnel, and urgent need to improve the rationality of construction.

Figure 1 The optical cable expansion planning method provided by the embodiment of the present application can include:

[0068] Step 100, optical cable resource information is acquired;The optical cable resource information includes the optical cable attribute, connection resource and associated optical fiber information of each optical cable;

[0069] Step 200, the optical cable morphology of each optical cable is determined according to the optical cable resource information, and the optical cable utilization rate of the optical cable is calculated based on the optical cable morphology;

[0070] Step 300, determine the optical cable utilization rate of the selected optical cable exceeding the preset threshold, and acquire the new resource information in the grid area to which the selected optical cable belongs;

[0071] Step 400, according to the new resource information, the optical cable expansion demand of the grid area is predicted, and the optical cable expansion demand scheme of the grid area is generated.

[0072] First, optical cable resource information is acquired, which includes the optical cable attribute, connection resource and associated optical fiber information of each optical cable, wherein the acquired optical cable resource information can be the optical cable resource information of the whole network, or the optical cable resource information in one or more areas to be expanded and planned. If the optical cable resource information in the area to be expanded and planned is acquired, the optical cable attribute, connection resource and associated optical fiber information of all optical cables in the area to be expanded and planned are included in the acquired optical cable resource information. Optionally, the connection resource of the optical cable is specifically the end device connected by the optical cable, and the end device includes A end device and Z end device, that is, the resource information of A / Z end connection of each optical cable is included in the acquired optical cable resource information. Optionally, the optical fiber information associated with the optical cable includes the local optical fiber associated with the optical cable.

[0073] According to the obtained optical cable resource information, the optical cable morphology of each optical cable is determined, and the optical cable utilization rate of each optical cable is calculated based on the optical cable morphology of each optical cable. It is known that based on different network transmission requirements, there are many different connection modes between optical cable sections, so that the optical cable has different morphologies, and different optical cable morphologies have different calculation methods of optical cable utilization rate.

[0074] Based on the calculated optical cable utilization rate of each optical cable, the candidate optical cable whose optical cable utilization rate exceeds a preset threshold is determined. For example, the preset threshold is 70%, and the preset threshold is determined according to the transmission carrying capacity of the optical cable, for example, the bottleneck of the transmission carrying capacity of the optical cable is taken as the threshold. Optionally, the transmission carrying capacity of the optical cable with different morphologies is different, so different thresholds can be corresponded.

[0075] Based on the preset threshold of each optical cable, the optical cable whose transmission carrying capacity is limited and exceeds the preset threshold is selected as the candidate optical cable that needs to be expanded. When the optical cable is expanded and planned, the utilization rate of the optical cable represents the available transmission carrying capacity of the optical cable, and is one of the important factors that need to be considered in the expansion planning. The newly built resource information in the grid area of each candidate optical cable is obtained, which represents the newly built optical cable resources in the grid area to which the candidate optical cable belongs. When the optical cable is expanded and planned, the newly built optical cable resources are also one of the important factors that need to be considered in the expansion planning.

[0076] According to the obtained newly built resource information, the optical cable expansion demand of the grid area is predicted, and an optical cable expansion demand scheme of the grid area is generated. The expansion demand scheme includes the areas that need to be expanded, the specific number of optical cables that need to be expanded in each area to be expanded, and can further include the optical cable morphology that needs to be expanded.

[0077] In this embodiment, the optical cable utilization rate is calculated by determining the optical cable morphology, so as to determine the candidate optical cable that needs to be expanded and has a high utilization rate. The optical cable expansion demand of the grid area to which the candidate optical cable belongs is predicted in combination with the newly built resource information in the grid area to which the candidate optical cable belongs, and an optical cable expansion demand scheme of the grid area is generated. Based on the optical cable resource information, the transmission carrying capacity of the optical cable is automatically analyzed by determining the optical cable morphology, so as to expand and plan the optical cable with high load and high load in combination with the newly built resource, which solves the problems existing in manual analysis and expansion planning, and improves the planning efficiency of the optical cable expansion.

If the optical cable attribute of the bifurcated optical cable is not the access introduction layer, the optical cable utilization rate of the bifurcated optical cable is a set of the calculated second optical cable utilization rates. Specifically, for each optical cable segment in the bifurcated optical cable, the utilization rate of each optical cable segment associated with the bifurcated optical cable is calculated, denoted as the utilization rate of the optical cable name (A-Z end). The A / Z end is the A end and the Z end of the local optical fiber associated with the optical cable segment.
