Automatic test system, equipment and method based on multi-channel radio remote unit

Abstract

The embodiment of the invention discloses an automatic test system based on a multi-channel radio remote unit, comprising a circulating device and a control device, wherein the circulating device comprises at least three ports; the three ports sequentially correspond to the multi-channel radio remote unit, an uplink side emission unit and a downlink side receiving unit; the control device comprises an uplink-downlink test module which is used for controlling all the channels of the multi-channel radio remote unit to respectively carry out uplink test with the uplink side emission unit and the downlink test with the downlink side receiving unit. The embodiment of the invention also discloses automatic test equipment and a method based on the multi-channel radio remote unit. According to the way above, the uplink test and the downlink test can be realized on a test platform by the embodiment of the invention, so that the test efficiency is improved, and manpower and equipment resources of the tests are saved; and furthermore, the equipment cost is greatly reduced.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of mobile communication, and in particular to an automatic test system, equipment and method based on a multi-channel remote radio frequency unit. Background technique [0002] The full name of the remote radio unit: Radio Remote Unit, the abbreviation: RRU. The remote radio unit is divided into two parts: the near-end unit, which is the wireless baseband control, and the remote unit, which is the remote radio unit (RRU). 3G networks use a large number of distributed base station architectures, and optical fiber connections are required between RRUs and BBUs (baseband processing units). One BBU can support multiple RRUs. The BBU+RRU multi-channel solution can well meet the indoor coverage requirements of large venues. [0003] The inventor of the present application has found in long-term research and development that the existing multi-channel TD RRU (Time Division Radio Remote ...

Problems solved by technology

[0003] The inventors of the present application have found in long-term research and development that the existing multi-channel TD RRU (Time Division Radio Remote Unit, Time Division Radio Remote Unit) test method is generally divided into uplink test and downlink test, and two sets of test environments are built respectively. Equipment and lines can be shared, but the actual situation is that all equipment and lines are equipped with two sets, which are used for uplink test and downlink test respectively, so the test efficiency is relatively low, and the test process is cumbersome and error-prone
