Realization method of multi-level network control center for satellite emergency communication system

Abstract

The invention discloses a multistage network control center implementation method for a satellite emergency communication system. A basic network service process ABS provides a Web service. A requestis sent to a network control program NCP through a unified interface agent. The NCP manages the central station channel unit through the RPC; the method comprises the steps that an ABS obtains hierarchical information from a unified interface provided by a hierarchical manager LTL, the LTL continuously updates information of a topological network in a broadcast mode, the ABS transmits an event message to a message server MTW through the unified interface, and the MTW uploads the information to a user browser in real time. Each network control center designed by the method can operate independently, and a superior network control center can access a next-level network control center.

Description

Technical field [0001] The invention belongs to the field of satellite emergency communication, in particular to a method for realizing a multi-level network control center for a satellite emergency communication system. Background technique [0002] The satellite emergency communication system is a star-shaped VSAT system in the KU frequency band, which is composed of a central station and a remote station to solve communication problems under emergencies. The network control center is the management and control center of the satellite system ground system. Its main function is to monitor, control and manage all satellite resources to ensure the reliable operation of the entire network. [0003] At present, most network control centers adopt multi-user and multi-authority methods for remote management. One way is to build only one network control center, and remote users and the network control center set up private network access. The advantage is that the network control center...

Problems solved by technology

One way is to build only one network control center, and remote users and the network control center set up private network access. The advantage is that the design of the network control center is simple. The disadvantage is that once the dedicated line network fails, remote users will not be able to access the system

Another way is to set up multiple network control centers. Users in different places use a dedicated network for data synchronization to ensure the accuracy of data. The advantage is that they will not rely too much on the network. Even if the network is temporarily disconnected, users in different places can also ensure that the system provides services normally. , the disadvantage is that the design of the synchronization mechanism is complicated, and problems are prone to occur during synchronization
