Description
Technical Field
The present invention relates to the field of mobile communications, and in particular, to a method and a system for debugging and testing a radio remote base station.
Background
Base stations of an existing LTE (Long term Evolution) system and TD-SCDMA (time Division-Synchronous Code Division Multiple Access) system mostly adopt a distributed structure, and a distributed Base station refers to a Base Band Unit (BBU) and a Remote Radio Unit (RRU) of a Base station, which are separately placed as independent modules and connected by an optical fiber through an optical interface. The distributed base station system has the advantages of large capacity, high integration level, flexible networking, applicability to various coverage scenes, low power consumption, high reliability and low equipment cost, thereby greatly reducing the network sputtering and maintenance cost.
In a mobile communication system, under the influence of objective factors such as cost, power consumption and networking flexibility, the system has higher and higher requirements on the processing capability of a base station single board, and often the base station single board is required to complete data processing of multiple cells and multiple antennas, and also has high requirements on the resource utilization rate, the integration level and the like of the base station single board. Especially in the current TD and LTE systems, because of the radio remote technology, the BBU and the RRU are separated, and the BBU and the RRU are connected by optical fiber, the difficulty of testing the base station is increased. Therefore, how to perform a test to ensure the correctness of the functions of the BBU and the RRU under the condition that the resource utilization rate of the base station board is high has become one of the problems that need to be solved at present.
In the existing test method for the single board of the base station, on the premise of not increasing a peripheral test device, a certain test method is added in the BBU and the RRU by using an embedded application program through a software program to test and verify the correctness of the BBU and the RRU. Therefore, this method can be used only for simple tests, and cannot satisfy tests that require a large amount of data for analysis.
In the prior art, special equipment is also usually adopted to achieve certain RRU data acquisition and testing, for example, special test equipment simulating BBU is used to respectively test whether uplink and downlink physical channels of RRU are normal. The method for testing the uplink channel comprises the steps of inputting data of a signal source through an antenna port, transmitting the data to analog BBU equipment through optical fibers after passing through each submodule of the RRU, analyzing the data by the analog BBU, and judging whether the uplink channel is normal or not according to an analysis result; the method for testing the downlink access comprises the steps that downlink data are sent by the analog BBU and transmitted to the RRU after passing through the optical fiber, the RRU sends the data to the antenna port through the downlink access, the output of the antenna port is measured through an instrument, and whether the downlink access is normal or not is judged according to a test structure. However, although the dedicated device can test the uplink and downlink channels of the RRU at the same time, it cannot acquire uplink data of the RRU and cannot test the BBU, and furthermore, it is difficult to connect the RRU to be tested in the whole environment by using the dedicated BBU simulation test device due to the limitation of conditions such as hardware environment, and the like, and the test can be performed only in the single board environment, and if the test is performed in the whole environment, additional interface cooperation needs to be added, so that the existing test device and method are lack of flexibility.
