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 fault code 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 protoco...

Abstract

The invention provides a method and a device for detecting and reporting automatic rollback of software in an optical network terminal (ONT) of a communication system. The method comprises the following steps: judging whether new software is downloaded successfully or not by ONT software; if so, setting an upgrading mark and updating a prior software version variable by virtue of a software version number in a current software version variable, and if not, reporting that the downloading of the new software is failed; then automatically restarting; updating a current software version variable by virtue of the software version number of the current software; then judging whether the upgrading mark is set or not; if so, further judging whether the software version number in the current software version variable is consistent to a software version number of the prior software version variable or not; and if so, reporting software rollback to an automatic configuration server and eliminating the upgrading mark, and if not, eliminating the upgrading mark, so that the software is upgraded successfully.

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...
