The present invention relates to the field of data transmission technology, and more specifically, to a data processing method, device, equipment and storage medium.

Background technique

In the field of mobile communications, with the continuous development of services, user needs are increasing. It is becoming more and more difficult for current mobile communications equipment to meet user needs for different application scenarios. On the one hand, in order to meet the user’s business needs, on the other hand Equipment manufacturers must control equipment costs within the acceptable range of operators, which puts forward higher requirements for the flexibility of mobile communication equipment. Repeater is a part of mobile communication equipment, and optical fiber transmission is an important part of repeater equipment. Whether it can improve the flexibility of the equipment and whether it can efficiently use the transmission bandwidth directly affects the applicability of the equipment.

As shown in Figure 1 is a communication system including a repeater and a base station. The repeater includes a digital access unit (DAU) and a digital remote unit (DRU). The digital access unit The base station (Base Transceiver Station, BTS) couples multiple carrier signals through the feeder and transmits them to the lower-level digital remote unit through optical fiber for signal coverage. The digital remote unit at this level is daisy-chained or other cascaded methods. The multiple carrier signals received from the upper level are transmitted to the digital remote unit of the lower level through the optical fiber, so as to recycle, and finally realize a large area of signal coverage.

In the traditional repeater system, the number of carriers, channel bandwidth, sampling rate, and IQ data bit width of the carrier signal transmitted by the digital access unit and the digital remote unit are generally set in advance. The digital access unit The digital remote unit encapsulates these carrier signals into CPRI frames according to a preset method, and then transmits them through optical fibers. The process of encapsulating the carrier signals into frames at the transmitting end is called framing, and the receiving end encapsulates the frames according to the reverse process of framing. The method of operation is called deframing. In the traditional repeater system, if the number of carrier signals, channel bandwidth, sampling rate, and IQ data bit width of the carrier signal to be sent changes, the transmission module of the repeater system cannot meet the data transmission requirements. R&D personnel need to reassess the requirements, redesign the DAU and DRU framing methods, and modify the transmission module to meet the requirements.
