Network communication between CORS base station and control center

Abstract

In A stable and reliable communication link is required to be established between the CORS base station and the control center, in this paper the Synchronous Digital Hierarchy is selected as be the main communication network, and high-speed interconnection InfiniBand between workstations of the control center and base stations is realized; In view of the status there are no alternative communication line or there are only the ordinary telephone lines to back up in China and taking China's latest progress of 3G mobile communication into comprehensive consideration, the 3G communication is introduced as the backup means of communication of the CORS system, Through this mode the reliability and the availability of the CORS system are greatly improved.
