Abstract

The invention provides a method, a device and a system for aging a radio remote unit and the radio remote unit. The method comprises the following steps: S1, transmitting a control signal to at least one tested radio remote unit (RRU) in order that each tested RRU generates a single-tone signal according to pre-stored single-tone source data and that each tested RRU transmits the single-tone signal; S2, acquiring the test parameters of each tested RRU respectively, wherein the test parameters comprise a numeric field output power detection value, a numeric field reflection power detection value, an intermediate-frequency board feedback link gain, a power amplification board output power detection link gain, a power amplification board reflection power detection link gain and filter insertion loss; and S3, generating a test result of each tested RRU according to the test parameters of each tested RRU respectively. Through the method, the device and the system for aging the radio remote unit and the radio remote unit provided by the invention, the quantity of RRUs which are aged simultaneously can be increased.

Description

technical field [0001] The present invention relates to the field of communication technology, and in particular to a method, device, system and remote radio unit for aging radio frequency units. Background technique [0002] The remote radio unit (RRU, Radio Remote Unit) is used to convert the baseband optical signal into a radio frequency signal at the remote end, amplify and transmit it. RRU is divided into 4 large modules: intermediate frequency module, transceiver module, power amplifier and filter module. The digital intermediate frequency module is used for modulation and demodulation of optical transmission, digital up-down conversion, A / D conversion, etc.; the transceiver module completes the conversion of intermediate frequency signals to radio frequency signals; and then transmits radio frequency signals through the antenna port through the power amplifier module and filter module go out. The burn-in test is to test the equipment with power and signal at room te...

AI Technical Summary

Problems solved by technology

[0006] To control the RRU through the main station, the developer of the aging software must be proficient in the control process of the main station, which increases the complexity of developing the aging environment

At the same time, since the master station itself is a complex system, it also makes operation and maintenance more difficult

The main station needs to be configured before the burn-in test. Different types of RRU test system network elements are not the same, and the environment switching is difficult and time-consuming, and the versatility is poor.

[0007] Due to the use of optical fiber connections, the configuration of optical modules affects the number of RRUs connected, and the number of RRU aging tests that can be performed simultaneously in an aging environment is limited, making it unsuitable for large-scale applications; optical fibers are not as durable as network cables, and during the aging process It is a consumable item, and the cost of the aging environment is relatively large

[0008] It can be seen from the above description that the number of RRUs aging simultaneously in the prior art is relatively small
