Description

Background technique

In a distributed base station, the traditional base station model is split into two parts: a central base station and a remote radio unit. The central base station includes a baseband and control module, which is responsible for baseband data processing of the signal, and control and management of the base station. The remote radio unit includes an intermediate frequency module, a radio frequency transceiver, and the like, and is responsible for the intermediate frequency and radio frequency processing of the signal. The central base station is located in the equipment room, and the remote radio unit is placed next to the antenna.

The device may further include:

An example of a device for implementing optical port link auxiliary communication includes the following components: a data transmitting device disposed at a transmitting end of an optical module, and a data receiving device disposed at a receiving end of the optical module.

The data transmitting device may include a controller, an optical module, and a fiber optic component, and mainly performs parallel-to-serial conversion on the data to be sent when data is detected in the data transmission area, and adopts a specific communication protocol according to a specific rate. The output enable pin (TDIS) pin of the optical module is controlled (when the value is 0, the signal level output to the TDIS pin is low, the output of the optical module is turned off, and the output of the optical signal is stopped; When 1, the signal level output to the TDIS pin is high, the output of the optical module is turned on, and the optical signal is output).

The data receiving device may include optical modules, optical fibers, and controllers. The controller detects the LOS signal output by the optical module in real time, and performs the inverse operation on the received LOS value signal in the detecting module (when the LOS signal is detected as 0, the optical signal is normal, and after the inverse is 1, the control Tdis is The output signal of the terminal is high level and consistent. The received data is parsed according to a specific protocol.

In addition, the data receiving device may further include a data storage module, a data parsing module, a data decoding module, and the like.

Due to the influence of the switching control rate of the optical module, the communication rate is very low. Therefore, in order to improve the utilization efficiency of the controller, the transmitted/received data needs to be stored in the receiving data storage module/transmission data storage module for storage processing.

The data packing module encodes the data to be sent according to a specific communication protocol according to the protocol rule, and then provides the data to the data sending module for transmission. For the decoding of the receiving part, the data parsing module decodes the received data according to the format of the protocol.

The data parsing module includes two parts: the encoding of the transmitted information and the decoding of the received data. Since the transmission data rate is low, and the content of the communication is often very large, it takes a long time to directly transmit the data through the embodiment of the present invention, which affects the communication efficiency of the base station. In addition, the embodiments of the present invention are mainly used for Auxiliary communication, so the information to be sent is replaced by the complete information, which reduces the amount of data transmission and improves the transmission efficiency. The receiving part restores the received information on the receiving side according to the code correspondence table. Thereby implementing the auxiliary communication function.

The implementation of the technical solution will be further described in detail below with reference to the accompanying drawings:

From the description of the optical module pins and the description of the electrical characteristics of the optical module signals (see Table 1 and Table 2 below), it is feasible to set the TDIS signal at the transmitting end and detect the LOS signal at the receiving end.

Table 1 optical module pins

Table 2 Optical module signal electrical characteristics

The receiving end LOS can reflect the state of the originating TDIS (1 to 1, 0 to 0) in real time, and the rise and fall time is negligible relative to the application. Through the analysis of the above experimental data, the optical port information can be reported by turning on and off the output state of the TDIS of the transmitting end, and the function is independent of the rate of the optical module.

This solution can be implemented by related devices such as FPGA or CPU. In the receiving direction, it is necessary to open a dedicated data receiving storage space (may be, but not limited to, implemented in RAM), and the space size is 64*9 bits. The high bit is the data check result bit, and the lower 8 bits is the data storage space. At the time of data reception, the logic or processor automatically performs parity check on the received bytes and fills the contents of the data frame into the RAM. Where C indicates the accuracy of the data frame even check received this time, 0 means the check is passed, and 1 means the check fails the data error. As shown in Figure 9 (high bit first, low bit later).

In the sending direction, a dedicated data transmission storage RAM space is opened, and the space size is 64*8 bits. The FPGA or the processor periodically checks whether the data in the RAM space is empty. When the data to be transmitted is detected, the parity result is automatically calculated and added to the end of the data for transmission. The data transmission format is shown in Figure 10.

In one example, the CPU processor is treated as follows:

Step 101: The CPU processor of the board starts the optical port auxiliary communication mode when detecting that the optical port link receiving link is interrupted for more than a certain period of time or receiving a command of the auxiliary communication mode when the pre-stage transmission is required;

Step 102: The processor constructs the content to be sent according to the service mode by using a fixed data format.

Step 103: After completing the data construction, the processor fills the data to be sent into the data transmission dedicated storage interval, and after the data is completed, writes the data filling end identifier, and notifies the data sending module to start the data transmission;

Step 104: The data sending module periodically detects whether it is necessary to activate the optical port auxiliary communication mode and enter the auxiliary communication mode.

Step 105: When entering the auxiliary communication mode, the processor periodically checks whether there is data to be sent in the data transmission storage space, and if so, constructs the data packet content according to a specific protocol, and converts the serial data into a predetermined baud rate. It is output to the TDIS control pin of the optical module to perform output transmission control of the optical module.

Step 106: At the receiving end, the processor detects the LOS signal output by the optical module in real time and performs serial-to-parallel conversion according to a specific baud rate.

Step 107: The processor performs data according to a specific protocol rule after receiving the parallel data. Validity determination, fill in the qualified data to the data storage module;

Step 108: The processor reads the data from the memory by using an interrupt or a timing query, and converts the received data according to a specific protocol rule and provides the data to the upper layer software for use.

Through the above method, the auxiliary communication function of the optical port is realized.

Step 604: The data receiving device detects the signal of the LOS pin in real time according to a specific baud rate, and performs serial-to-parallel conversion to determine whether the received data is the format content of the auxiliary communication.
