Satellite-mounted time-space-time switching network

摘要

The present invention relates to an existing TST type switching network in which an on-board baseband processor (OBP) of a next generation satellite communication system is constituted by a receiving side time switch, a base band space switch and a transmitting side time switch. The present invention relates to a TST switching network in which the reliability of the entire system is improved by dividing the TST switching network in the form of m N / m x N / m switches. According to the present invention, Thereby preventing a fatal total failure of the system due to failure of the switch when there is one space switch and processing traffic as remaining space switches even if a part of the plurality of divided space switches fails, do.
