Abstract

The invention provides TD-SCDMA (Time Division-Synchronization Code Division Multiple Access) base band link loopback detection method and a base station. The method comprises the following steps that: a BBU (Base Band Unit) sends downlink detection data to an RRU (Radio Remote Unit) through a downlink base band link; the RRU receives the downlink detection data from the downlink base band link; the RRU takes the received downlink detection data as uplink detection data and sends back the uplink detection data to the BBU through an uplink base band link; and the BBU conducts comparison between the downlink detection data and the uplink detection received from the uplink base band link, and if the comparison results are different, the fault is detected. In the invention, link loopback detection can be actively done at regular time through adding a loopback mechanism in the base band link of the TD-SCDMA, thus timely detecting and discovering faults of service channels in the base band link, quickly conducting later troubleshooting and processing, making up for the lagging defects of the traditional fault reporting mode and improving the detection efficiency.

Description

technical field [0001] The invention relates to a TD-SCDMA baseband link loopback detection method and a base station, belonging to the technical field of Time Division-Synchronous Code Division Multiple Access (TD-SCDMA for short). Background technique [0002] The TD-SCDMA base station system includes an indoor base band processing unit (Base band Unit, referred to as: BBU) and a radio remote unit (Radio Remote Unit, referred to as: RRU). Wherein, the BBU device has single boards such as a baseband processing board and an interface board connected to the RRU. RRUs can have various networking forms such as cascading. [0003] The baseband link runs through the baseband processing board, the interface board and the corresponding RRU in the BBU. Due to the complexity and variety of interconnection between various parts in the base station system, when the baseband link fails, it is difficult to detect and find the fault in time, and the detection efficiency is low.
