AI Technical Summary

Problems solved by technology

Because the OLT needs to be connected to multiple ONUs, and each ONU has to be connected to multiple user-side terminal devices, the entire system involves a rather complex topology, which has caused certain difficulties in its daily operation, management and maintenance.
For example, when one of the optical network units or optical line terminals fails, it is difficult to detect and troubleshoot the specific source of the failure in time

Embodiment Construction

[0036] Hereinafter, exemplary embodiments according to the present application will be described in detail with reference to the accompanying drawings. Apparently, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments of the present application. It should be understood that the present application is not limited by the exemplary embodiments described here.

[0037] Scenario overview

[0038] As described above, in the OLT system, the OLT manages signaling and monitoring information from the ONU, thereby providing maintenance and assignment functions for the ONU and itself. Because the OLT needs to be connected to multiple ONUs, and each ONU has to be connected to multiple terminal devices on the user side, the entire system involves a rather complex topology. Accordingly, it is also expected to provide a system that can monitor the entire system status on the OLT side. scheme.

Abstract

The invention discloses an optical line terminal system which adopts a feature extraction and fusion classification mode based on deep learning. Association information of states among the ONUs at the time points and state association information among different user side terminal devices connected with the ONUs in the topological structure of the OLT system are mined through the convolutional neural network; and the information of each edge length is further fused by applying a signal propagation rule in free clearance. Therefore, the current state data and the historical state data of the currently monitored OLT are further combined, so that the state of the whole optical system is effectively monitored from one side of the OLT.

Description

technical field [0001] The present invention relates to the communication field, and more specifically, relates to an optical line terminal system. Background technique [0002] With the advent of the era of gigabit access, OLT (Optical Line Terminal: Optical Line Terminal) is the core node of the access network. An ONU (Optical network unit: Optical Network Unit), and the ONU is connected to the terminal equipment on the user side, thereby providing the terminal equipment with a network access function. [0003] In addition, in the OLT system, the OLT manages signaling and monitoring information from the ONU, thereby providing maintenance and assignment functions for the ONU and itself. Because the OLT needs to be connected to multiple ONUs, and each ONU has to be connected to multiple terminal devices on the user side, the entire system involves a rather complex topology, which has caused certain difficulties in its daily operation, management and maintenance. For exampl...
