Embodiment Construction

[0019] Hereinafter, the extension of TR069Amendment4 and the extension of TR098 are described first.

[0020] (1) Extension TR069Amendment4

[0021] In one embodiment, the faultcode in the fault structure in the TransferComplete message can be extended to indicate that the new software upgrade fails and the old software is rolled back, as shown in the following table:

[0022]

[0023]

[0024] It should be noted that setting the fault code to 9800 indicates that the new software upgrade fails and rolls back to the old software is just an example. In other examples, the fault code can also be set to other values ​​to indicate that the new software upgrade fails and rolls back The occurrence of the situation of the old software is understandable to those skilled in the art, and will not be repeated here.

[0025] (2) Extended TR098

[0026] To realize the purpose of the present invention, a node InternetGatewayDevice.X_SoftwareMgnt is newly defined in the TR098 protocol...

Abstract

The invention provides a method and a device for detecting and reporting software automatic rollback in an optical network terminal of a communication system. First, the ONT judges whether the new software has been successfully downloaded; if yes, the upgrade flag is set, and the previous software version variable is updated with the software version number in the current software version variable; if not, then the report fails to download the new software; then, automatically Restart; then, update the current software version variable with the software version number of the currently installed software; then, judge whether the upgrade flag has been set; if so, then further judge whether the software version number in the current software version variable It is consistent with the software version number in the variable of the previous software version; if yes, report the software rollback to the automatic configuration server, and clear the upgrade flag; if not, clear the upgrade flag, indicating that the software upgrade is successful.

Description

technical field [0001] The invention relates to a communication system, in particular to a method and a device for detecting and reporting software regression in an optical network terminal of the communication system. Background technique [0002] TR069 provides another way to remotely manage Optical Network Terminal (ONT) software. It can request the download of dedicated software from the Auto Configuration Server (ACS) to the ONT, and install the new software to the ONU once the download is complete. However, the problem currently faced is that the transferComplete message will still report that the upgrade was successful even if the new software fails to start and rollbacks to the old software. [0003] For this, the operator must obtain software version information from the ONT, and manually compare the pre-update software version with the new software version. If the comparison is identical, a rollback occurred and the upgrade failed; if the new version is the expec...
