In the prior art, on the BSC side, there is no design to download the GCM version. To change the version, you need to unplug the GCM single board at the BSC, take out the MCU chip, and use a programmer to burn the version data into the chip. The cost of changing versions is very high

Embodiment Construction

[0038] In order to realize the download, the master-slave device communication must first be realized according to the flow of data sending and receiving. The main implementation steps include the master device initiating a communication command, the slave device receiving, parsing, executing the command and returning the execution result, and the master device performing corresponding actions according to the received execution result of the slave device, wherein the master device initiates the command and the slave device returns the execution result It involves framing processing, while the slave device accepts and parses commands, and the master device receives the return result from the slave device involves deframing processing.

[0039] The flow of data sending and receiving is shown in Figure 1. Sending data to the serial port for framing includes: 485 communication system processing data of upper layer software; sending escape processing for data; sending cyclic redun...

Abstract

The invention relates to a BSC BOOT abnormal downloading method based on MCU, which is used for a CDMA2000 mobile communication system and comprises: step 1, after a GCM main board and / or a spare board receive downloading enabling request sent by OMP, judging whether to perform downloading enabling, and returning the judged results to the OMP by the GCM main board; or after the GCM main board and / or the spare board receive the downloading enabling request sent by the OMP, neglecting the downloading enabling request; and step 2, if the OMP judges that the enabling downloading can be performed,performing normal downloading under the control of the OMP; and if the OMP judges that the enabling downloading cannot be performed or the response waited by the OMP for the downloading enabling request is overtime, sending the indication information that the GCM main board or the spare board enters an abnormal downloading flow to the GCM main board and / or the spare board by the OMP, and performing abnormal downloading treatment after the GCM main board responds. The method and the system can achieve the treatment for the abnormity occurred during downloading, and normally download the BSC BOOT as much as possible.

Description

technical field [0001] The invention relates to a CDMA2000 mobile communication system, in particular to an MCU-based CDMA2000 BSC BOOT abnormal download method and system. Background technique [0002] In the overall design process, the MCU board on the base station controller (BSC) side adopts the method of sharing the communication bus for communication arbitration and software download; when the download is started, the operation and maintenance processing (OMP) main board does not pull the enabling signal Moreover, the global positioning control module (GCM) has active and standby operations. Due to these factors, many abnormalities will occur during the download process, but there is no BSC BOOT (bootstrap) download for abnormalities in the download process. solution. In the prior art, on the BSC side, there is no design to download the GCM version. To change the version, you need to unplug the GCM single board at the BSC, take out the MCU chip, and use a programmer t...
