Abstract

The invention discloses a satellite communication system large-scale networking simulation test method, equipment and system. The method comprises the following steps: configuring basic network element information required to be simulated in a configuration file of an end station according to end station information registered on an NMS, and taking the end station as an end station simulator; splitting sub-scenes according to the need of large-scale networking verification, setting a set of interaction process of an end station and an NCS for each sub-scene, and packaging different interactionprocesses into different service models; configuring a service model in which each piece of basic network element information interacts with the NCS; generating a simulation instance according to thebasic network element information of the configuration file; and constructing a corresponding signaling message according to the service model, and simulating and executing the interaction process ofall simulation instances and the NCS. One terminal station is used for simulating the process that dozens or even hundreds of terminal stations interact with the NCS at the same time, a normal or abnormal test scene is flexibly constructed, the requirement for the number of equipments is reduced, and reliability and fault tolerance are improved.

Description

Technical field [0001] The invention relates to satellite communication, and is particularly related to a large-scale networking simulation test method, device and system of a satellite communication system. Background technique [0002] In the DAMA (distribution on demand) satellite communication system, the NCS (Network Controller) conducts unified control and management of the entire network, including equipment access to the network and resource allocation, etc. The entire process is completed through signaling interaction. The basic process is that NCS broadcasts its own information in the subnet through the main station's TDM carrier. After the end station receives the broadcast, it sends the network access signaling to the main station, and the main station transfers it to NCS for processing. After the end station is connected to the network, it will also initiate resource application signaling to the NCS when there is a business. In this networking mode, an NCS and a mas...

AI Technical Summary

Problems solved by technology

[0003] When there are a large number of end stations, the massive signaling packets may exceed the processing capabilities of the NCS and the master station, resulting in abnormal functions

However, in the actual test, the laboratory environment often fails to meet the requirements for verifying large-scale networking due to the limited number of sites and equipment, which brings potential risks to live network applications
