[0005] However, the above-mentioned prior art calculates BLER and BER by the value of CRCI, which is essentially an indirect calculation method, without comparing the actual transmitted bit stream with the original correct bit stream, the obtained BER and BLER relatively low accuracy
Moreover, the above method is processed by the internal software of the base station, but there are many types of base stations at present, and the calculation software installed inside the various types of base stations is different, and the methods for calculating BER and BLER may also be inconsistent. Therefore, each The BER and BLER calculated by different base stations lack a unified standard and are not comparable
Moreover, the process of base station internal statistics is a black-box operation process for test users, which lacks transparency, data is likely to be falsified, and the fairness of test results cannot be guaranteed

The invention discloses a test system, a test device and a test method of performances of an up transmission channel of a base station. The test system comprises a signal generator and the test device. The signal generator generates radio frequency signals according to a preset original bit stream and sends the radio frequency signals to the base station; the test device is provided with configuration information comprising the original bit stream and used for triggering the base station to report a data frame by the up transmission channel, comparing a bit stream in the reported data frame with the corresponding original bit stream in the configuration information and then calculating a bit error rate (BER) and / or a block error rate (BLER) reflecting the performances of the up transmission channel according to the comparison result. The application of the invention can improve the accuracy of test results and guarantee higher comparability and fairness of the test results.
Description
technical field [0001] The invention relates to the technical field of mobile communication, in particular to a test system, a test device and a test method for testing the performance of an uplink transmission channel of a base station in a mobile communication system. Background technique [0002] In the third generation mobile communication system, the communication between the base station (Node B) and the mobile terminal is carried out through the Uu interface, and the communication between the base station and the base station controller (RNC) is carried out through the Iub interface. In data uplink, the base station needs to demultiplex the physical channel into an uplink transmission channel, and use the uplink transmission channel to send the data processed by the base station to the base station controller. When performing equipment index or performance tests on base stations, it is necessary to test whether the performance of the transmission channel meets the req...
