Embodiment 1

[0069] Please refer to figure 1 , Embodiment 1 of the present invention is:

[0070] A 5G distributed base station RRU device FPGA remote upgrade method, comprising steps:

[0071] S1. Run according to the basic version program in the first storage space;

[0072] That is, when the RRU device leaves the factory, the first upgrade status value 1 is written into the EEPROM, and the basic version program is pre-programmed in the first storage space. After the distributed base station is set up and activated, the RRU device starts, and the FPGA reads from the first storage space by default. Take the basic version program, after the FPGA is started, read the upgrade status value of the EEPROM module as the first upgrade status value 1, then the FPGA does not perform the program upgrade, runs according to the basic version program in the first storage space, and the device works normally;

[0073] S2. Receive the upgrade instruction and the first upgrade program remotely sent by t...

Embodiment 2

[0087] Please refer to figure 2 and image 3 , the second embodiment of the present invention is:

[0088] A 5G distributed base station RRU equipment FPGA remote upgrade terminal 1, including a memory 3, a processor 2, and a computer program stored on the memory 3 and operable on the processor 2, and the above-mentioned embodiment is realized when the processor 2 executes the computer program Step S1 to step S4 in one.

[0089] like image 3 As shown, in this embodiment, the processor 2 is equivalent to the FPGA6 in the RRU5, and the memory 3 is any storage device in the RRU5. The storage device of the computer program of steps S1 to S4 is composed.

[0090] In this embodiment, the overall architecture between BBU4 and RRU5 is as follows image 3 As shown, corresponding to the analog switch 7, EEPROM8, latch 11 and reset module 12 in the first embodiment above, wherein, FLASH19 is the first storage space for storing the basic version program, FLASH210 is the second stor...

Abstract

The invention discloses an FPGA remote upgrading method for 5G distributed base station RRU equipment and a terminal. The FPGA remote upgrading method comprises the following steps: performing runningaccording to a basic version program of a first storage space; and receiving an upgrading instruction and a first upgrading program which are remotely sent by the BBU, unloading the first upgrading program to the second storage space, and after unloading, performing running according to the first upgrading program of the second storage space to finish upgrading. According to the method, the FPGAof the RRU beyond several kilometers can be remotely upgraded by technicians through the BBU in a machine room; the upgrading efficiency is improved, the operation and maintenance cost is reduced, thehardware cost of the upgrading circuit is reduced, the program development work of a peripheral CPU or a CPLD is reduced, and the reliability of remote upgrading can be guaranteed.

Description

technical field [0001] The present invention relates to the technical field of communication equipment, in particular to a method for remotely upgrading FPGA of RRU equipment of a 5G distributed base station and a terminal. Background technique [0002] With the development of 4G and 5G mobile communication technologies, operators are building more and more distributed base stations. Distributed base stations are a new generation of modern products used to complete network coverage. Its main feature is that the radio frequency processing unit (RRU) and the base station baseband processing unit (BBU) are separated and connected through optical fibers at the same time. During network deployment, the BBU, core network, and wireless network control equipment are concentrated in the computer room, and connected to the RRU deployed on the planned site through optical fibers to complete network coverage, thereby reducing construction and maintenance costs and improving efficiency. ...
