Description
Technical field
The present invention relates to communication technical field, particularly relate to the method for aging Remote Radio Unit, device, system and Remote Radio Unit.
Background technology
Remote Radio Unit (RRU, Radio Remote Unit) sends out for base band light signal being changed into radiofrequency signal amplification at far-end.RRU is divided into 4 large modules: ifd module, Transceiver Module, power amplifier and filtration module.Data intermediate frequency module is used for the modulation /demodulation, Digital up and down convert, A/D conversion etc. of optical transport; Transceiver Module completes the conversion of intermediate-freuqncy signal to radiofrequency signal; Again through power amplifier module and filtration module, radiofrequency signal is launched by antenna opening.Burn-in test is before use equipment, carries out normal temperature and powers up plus signal test, the device in equipment is operated at full capacity for a long time, exposes defect in the early stage, and be unlikely to just to go wrong when user just brings into use equipment.Meet the quality standard of shipment in order to ensure RRU, need to carry out burn-in test to it.
In prior art, RRU aging techniques adopts Fiber connection main website and RRU, then by operating state that PC controlling center makes RRU be in transmit.Owing to using main website to control, just can transmit so also need to set up home cell to RRU.Ageing environment is by after main website on Fiber connection, and the process of establishing of community needs about three minutes.If the luminous power of access is abnormal, RRU normally will start thus cause community to set up, and now also needs to investigate each side factors such as environment, operation and maintenance relative complex.Because needs use main website, RRU often there will be environmental abnormality when accessing main website and cannot normally access, and environmental problem affects burn-in test efficiency, connects complexity simultaneously, controls difficulty, thus makes traditional ageing environment be difficult to safeguard.
According to different collocation methods, main website once can access multiple stage RRU, thus realizes batch aging.The RRU that separate unit main website once can access is limited, and when full configuration is put also with regard to the RRU of RRU or 16 2 antennas of 48 antennas, this makes batch aging RRU need the auxiliary realization of a large amount of main websites.
Main website can be connected by star fashion or cascade system with RRU, no matter adopts which kind of mode, in aging, all can be subject to the quantitative limitation of optical module appearance.For example, CA (the Carrier & Antenna of the optical module support of a 10Gbps speed, carrier wave and antenna) number is 192, needed for the home cell of an antenna 20M compression, CA number is 12, if that aging is 8 antenna RRU, so the CA number of RRU needs is 96.That is, 28 antenna RRU once can only be with in the compression home cell that 10Gbps optical module sets up 20M simultaneously.The RRU limited amount that a main website accesses simultaneously, if the RRU of simultaneously aging 40 8 antennas, then needs 20 ageing environment to meet testing requirement.
By main website control RRU, the developer of aging software just must be proficient in the control flow of main website, adds the complexity of exploitation ageing environment.Meanwhile, because main website itself is a complicated system, this also makes operation and maintenance become more difficult.Need to be configured main website before burn-in test, the test macro network element cloth of dissimilar RRU is joined not identical, and environment changing difficulty is consuming time, poor universality.
Due to employing is Fiber connection, the RRU quantity of the configuration impact access of optical module, and a set of ageing environment carries out the limited amount of RRU burn-in test simultaneously, causes it to be not suitable for large-scale application; Optical fiber does not have netting twine durable, in ageing process, belong to easily-consumed products, larger to the cost overhead of ageing environment.
