Remote-updating and version-switching method of repeater equipment embedded software

Abstract

The invention relates to the performance optimization of repeater equipment in communication field. The remote-updating and version-switching method of the repeater equipment embedded software comprises the following steps: 1) an OMC or OMT command is received in real time, if the command is an update command, go forward to step 2; if the command is a version-switching command, skip to step 5; and if the command is not received, skip to step 6; 2) an update document data packet is received from the OMC or OMT, and the received update document data packet is stored in a download process-memorizing region; 3) a download process code in the download process-storing region is programmed into the application process region of a singlechip; 4) the code data of the application process region is read byte by byte and written into a new version process-storing region; 5) when a currently running process is a new version process, a process code in an old version process-storing region is programmed into the application process region of the singlechip, otherwise, the process code in the new version process-storing region is programmed into the application process region of the singlechip; and 6. the monitor mode of the application process is executed. The method can realize the remote updating and the switching between the new process version and the old process version.

Description

technical field [0001] The invention relates to performance optimization of repeater equipment in the communication field, in particular to a method for remote upgrading and version switching of embedded software of repeater equipment. Background technique [0002] The monitoring software running on the repeater monitoring system needs to be upgraded. Since the installation locations of the repeaters are relatively scattered, and generally the installation locations are relatively remote, on-site upgrades are troublesome. Therefore, it is necessary to remotely upgrade the monitoring software on the repeater monitoring system, that is, in the monitoring center, for the selected repeater, upgrade the monitoring software running on the monitoring system through remote downloading, so as to realize timely New monitoring functions or address software defects, reducing maintenance costs. Remote upgrade requires high reliability, high success rate, and high efficiency. [0003] ...

AI Technical Summary

Problems solved by technology

[0013] 1. The repeater monitoring system stores the received new code in the memory (RAM). If the system is powered off during the transmission, the entire upgrade process will be interrupted, and the downloaded new code cannot be saved. It can only be downloaded again next time. ,waste time

[0014] 2. After the download of the new code is completed, the application program area will be flashed directly. The old version of the application program cannot be saved. will stop working and cannot revert to an older version of the app to continue using
