Authorization management method and system for signal transmission bandwidth of das communication system

Abstract

Disclosed are an authorization management method and system for a signal transmission bandwidth of a DAS communication system. The system consists of an access unit, an extension unit, and a distal unit. The radio frequency access unit is connected to the extension unit. The extension unit is connected to the distal unit. The extension unit mainly implements the extension of a proximal unit port, the extension of a transmission distance, and a transmission bandwidth control function. The distal unit mainly implements the coverage of a radio frequency signal to a specific area. The signal transmission bandwidth of the extension unit is controlled by setting an authorization file formed by authorizing the transmission bandwidth on an extension unit device. When the signal transmission bandwidth configured by a user on the extension unit is not greater than the authorized bandwidth, the configuration becomes effective, and the system performs normal transmission. When the transmission bandwidth configured by the user on the extension unit is greater than the authorized bandwidth, the configuration is limited, the overflow bandwidth is not transmitted, and an abnormal indication is made. The present invention provides a flexible capacity allocation mode for a DAS, which indirectly expands the sales market.
