Embodiment Construction

[0037] The following combined with the attachment and embodiments further explain the present invention.

[0038] 1. System

[0039] like figure 1 This system includes tested computers, baseband data transceivers, to aging RRU, power load.

[0040] Tune the super -terminal monitoring and real -time acquisition of each aging RRU current status using the serial port and operating system;

[0041] The baseband data transceiver is used to send the baseband data source, which can be implemented using existing technologies. The baseband data transceiver has independent optical ports with optical fiber with the first -level RRU optical port 0 through optical fiber;

[0042] The optical port of the first level RRU that is aging is connected with the optical port of the second level RRU through the optical fiber, and so on.

[0043] Each output of each output of RRU is connected to the power load.

[0044] Two ways

[0045] The workflow of the system is like figure 2 The following is the t...

Abstract

The invention discloses a batched RRU aging system and method. The system comprises a modulation testing computer, a base hand data transceiver, ageing RRUs, and power loads. The modulation testing computer is connected with the base band transceiver through a serial port. The base band data transceiver is connected with a first-stage RRU fiber port 0 through an independent fiber port. The first-stage RRU fiber port 1 is connected with a second-stage RRU fiber port 0, and the RRUs of the later stages are connected in the same way. The radio frequency output ports of the RRUs are connected with the power loads. The method includes the steps that the base band data transceiver sets the working mode marked by fixed bytes in a base frame as the batched ageing mode and fills corresponding AxCs with all bandwidth data sources used for the operator tests, the RRUs obtains and configures the working mode as the aging mode, and obtained base hand data begin aging. The batched mixed connection aging of different systems, frequency bands and channel RRUs can be conveniently achieved, the complexity of the system is lowered, and cost is reduced.

Description

Technical field [0001] The invention involves the field of mobile communication, especially a system and method of batch aging of RRUs. Background technique [0002] With the continuous maturity of LTE technology, the successive commercial use of TD-LTE and FDD-LTE 4G networks.Increased new demand for the single -day production capacity of each RRU equipment supplier, and the aging of RRU equipment has become a bottleneck that restricts the single -day capacity of RRU equipment, especially the mixed connection involving different bandwidth, different frequency bands, and different channels.Ageing. [0003] In order to solve the above problems, there are two common practices for RRU aging: one is to build a complete ENODEB system. The BBU interface sends a signal to a multi -level connected RRU to aging. For this method, because the BBU itself itselfThe limit of capacity, with the increase in single -day production capacity, requires a large number of BBUs for aging testing. When ...
