Abstract

The invention discloses a base station receiving channel fault positioning method and a base station, and aims to solve the problems of low efficiency, long time and complexity of base station receiving channel fault positioning in the prior art. The method comprises the following steps of: after determining that signal power output by a receiving channel of the base station is abnormal, communicating a transmitting channel and the receiving channel of the base station; generating a carrier signal in a preset power threshold range, feeding the carrier signal into the transmitting channel and determining a first power value of the carrier signal after the carrier signal arrives at the output end of the transmitting channel, wherein the carrier signal arrives at the output end of the receiving channel through the transmitting channel and the receiving channel communicated with the transmitting channel; determining a second power value of the carrier signal after the carrier signal arrives at the output end of the receiving channel; and judging whether the base station fails or not according to the first power value and the second power value. Due to the technical scheme, the fault positioning process is simplified, the fault positioning efficiency is improved and human and material resources are saved.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method for locating a fault in a receiving channel of a base station and a base station with a function of locating a fault in the receiving channel of the base station. Background technique [0002] The WCDMA (Wideband Code Division Multiple Access) system is an interference-limited system. The signal quality, user capacity, and coverage of the network system are all related to the background noise of the base station. Excessive noise interferes with the It will increase the noise level of the receiving channel of the base station, resulting in a decrease in communication quality, user capacity and coverage. Therefore, detecting and locating the interference received by the uplink channel of the base station has become a difficult problem faced by base station designers and network maintainers. [0003] The interference to the base station channel mainly includes two aspec...
