Abstract: This disclosure is directed to a simulation system that verifies functionality and performance of an automated telecommunication cloud platform (“TCP”) which is used to configure hosts of cell sites and a mobile core of a 5G cellular network. The mock hosts are created with a required virtualization platform inventory of objects for implementing a 5G cellular network and registers the mock hosts with a mock centralized server management platform (“mock VC”). The mock hosts are used to simulate hosts of cell sites and a mobile core of a 5G cellular network using features of the TCP. Scale tests are used to verify functionality and performance of the TCP are performed on the mock hosts without any changes to the TCP.

Abstract: A computer-implemented method, medium, and system for implementing a pluggable diagnostic tool for Telco radio access network (RAN) troubleshooting are disclosed. In one computer-implemented method, one or more containerized network function (CNF) instances are generated in a container orchestration platform by a test system and by using a telecommunication cloud automation (TCA) platform executed in the container orchestration platform, where the test system is onboarded to the TCA platform, and the one or more CNF instances are associated with 5G RAN. A customer resources (CR) file is received by the test system, where the CR file defines multiple test cases associated with validation of the TCA platform. The CR file is transmitted to a cluster of nodes in the container orchestration platform. The validation of the TCA platform is executed at the cluster of nodes based on the one or more CNF instances and the CR file.

Abstract: A transient stability assessment method for an electric power system is disclosed. Transient stability tags and steady-state data of the electric power system before a failure occurs are collected from transient stability simulation data. Data sets under different predetermined failures are obtained based on a statistical result of the transient stability tags and a maximum-minimum method. A similarity evaluation index between different predetermined failures is constructed based on a Jaccard distance and a Hausdorff distance. Different predetermined failures are clustered based on a clustering algorithm. A parameters-shared siamese neural network is trained for different predetermined failures in each cluster to obtain a multi-task siamese neural network for the transient stability assessment.

Abstract: A method and device for storing high-concurrency data. The method comprises: receiving high-concurrency data sent from a plurality of clients (110); pushing the high-concurrency data into a primary data queue, and responding to a corresponding client (120); consuming the high-concurrency data in the primary data queue by using multithreading (130); fragmenting the high-concurrency data according to the number of local queues (140); pushing the fragmented high-concurrency data into the local queues (150); and consuming the high-concurrency data in the local queues and storing the high-concurrency data in a database (160). By means of data asynchronous storage, high-concurrency data is temporarily stored in the primary data queue and the local queues, thereby alleviating pressure on the database, avoiding the problem of a database crash in the case of a high-concurrency storage, and improving the efficiency of storing high-concurrency data.
