Problems solved by technology

[0003] However, in the prior art method for transmitting data between base station boards, since the reading and writing of data on the single board side is a sequential process, that is to say, the data reading and writing process is a serial process, so in There are defects in data transmission: when the amount of data increases, the time for the message reading task to read the data and the time for the data to be written to the storage medium will prolong accordingly. At this time, the actual process of data transmission is: reading, waiting for reading , write, write wait
Since the data transmission on the board side is a serial process, the waiting time when data is read and written cannot be fully utilized, resulting in low efficiency of receiving data on the board side
[0004] On the other hand, the efficiency of receiving data on the board side is affected by the efficiency of writing to the storage medium. Also, because the data reading and writing process is a serial process, the data must wait for the writing to be completed before the data can be read. Therefore, when the data volume increases and the speed of writing data to the storage medium slows down, the message reading task will not receive messages for a long time, which will reduce the efficiency of data transmission on the board side

[0053] First embodiment: figure 2 It is a work flow diagram of the first embodiment of the present invention. In this embodiment, first a section of buffer area is set, and the buffer area is divided into a plurality of sub-buffer areas; then the message reading task writes the data into the sub-buffer areas in sequence according to the address of the sub-buffer areas, and the message When the write task reads the data in the buffer area, it reads the data in the order in which they were originally written into the buffer area to avoid data confusion. The advantage of this method is: when the message reading task writes the data of the main control board into the buffer area, it writes in sequence according to the address of the sub-buffer area, and when the message writing task reads the data of the buffer area, it also follows the sub-buffer area address Easy to read. The following is the detailed process.

[0058] The second embodiment: in this embodiment, firstly, a buffer area is also set, and the buffer area is divided into a plurality of sub-buffer areas; different from the first embodiment, in this embodiment, the message reading task reads When the main control board data is read, the data to be read is numbered. For example, the main control board data can be numbered according to the chapters, and then the sub-buffer area without data can be found, and the sub-buffer area is randomly written. The message writing task is read When fetching the data in the buffer area, it is read in the order in which the data was originally written into the buffer area, that is, the number of the data is read out to avoid data confusion. The following is the detailed process.

[0059] The message reading task writes data into the buffer area according to the data number of the main control board, firstly obtains the semaphore of the sub-buffer area, and waits if the sub-buffer area is full...

Abstract

This invention provides a method for transmitting data between base station plates used in the transmission between a master control plate and a single plate, which first of all reads data of a master control plate and stores them temporarily then reads the temporarily stored data and writes them in a storage medium, which increases a step of temporarily storing data fetched from the master control plate to divide the steps of fetching data from the master control plate and writing data into the storage medium at the single plate side into two different independent processes so the fetch and write-in processes of data are parallel so as to save the process of waiting for fetching and writing-in to increase the transmission efficiency.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method for transmitting data from a main control board of a base station to each single board. Background technique [0002] The base station is composed of a main control board and a single board. The main control board saves the software of the entire base station. When the software of each single board needs to be upgraded, the main control board transmits the read software data to each single board, and the side of the single board receives the software data. The data are written to their respective storage media. The current method for transmitting data between base station boards is: setting a message reading task on the side of the single board, reading data from the main control board, and then sequentially writing it into the storage medium of the single board. [0003] However, in the prior art method for transmitting data between base station boards, since the re...
