(1) TR069Amendment4 is expanded
In one embodiment, the fault code in the fault structure in TransferComplete message can be expanded, is used to indicate new software upgrading failure and rollback extremely old software, shown in table specific as follows:
It should be noted that, fault code is set to 9800 expression new software upgrading failure and rollback to old software is only an example, in other examples, also fault code can be set to other values be used for representing that the failed also rollback of new software upgrading is to the generation of old this situation of software, this it will be appreciated by those skilled in the art that, therefore not to repeat here.
(2) TR098 is expanded
For realizing object of the present invention, a new definition node InternetGatewayDevice.X_SoftwareMgnt in TR098 agreement.By this node, ONT just clearly can know the software kit information of system.Shown in table specific as follows:
It should be noted that, the length of character string is defined as 64 characters and is only an example, and it will be understood by those skilled in the art that in actual applications, the length of character string also can be the character of any number, as long as can indicate software version exactly.
Below by the node InternetGatewayDevice.X_SoftwareMgnt based on definition new in the fault code expanded in above-mentioned TR069 agreement and TR098 agreement, the method for ONT detection according to an embodiment of the invention and reporting software rollback is described.
With reference to figure l, first, in step S101, ONT judges whether new software is downloaded successfully.If new software download success, then in step s 102, ONT arranges upgrading mark (upgrade flag), be such as 1 by upgrading traffic sign placement, and upgrade the software version number of PreviousSoftwareVersion variable with the software version number in CurrentSoftwareVersion variable.If new software is not downloaded successfully, then in step s 103, ONT reports the failure of new software download.
Then, in step S104, ONT is restarted automatically.
It is more than the step performed before ONT is restarted.
After ONT is restarted, in step S105, ONT upgrades the software version number in CurrentSoftwareVersion variable with the software version number of current institute mounting software.
Install unsuccessfully cannot enable due to downloaded new software may be there is in the process of restarting at ONT, therefore, software current installed in this case may or before old software.Certainly, if the new software installation of downloading after successfully enabling, the version number of current institute mounting software is exactly the software version number of downloaded new software.
After ONT is restarted, in order to detect the situation whether software rollback occurs, such as, so in step s 106, ONT judges whether upgrading mark is arranged, and, whether upgrading mark is 1.If upgrading mark is arranged, then in step s 107, ONT judges that whether the software version number in CurrentSoftwareVersion variable is consistent with the software version number in PreviousSoftwareVersion variable further.If upgrading mark is not arranged, then terminate this flow process.
If ONT judges that the software version number in CurrentSoftwareVersion variable is consistent with the software version number in PreviousSoftwareVersion variable, then in step S108, ONT to ACS reporting software rollback, then, enter in step S109, ONT removes upgrading mark.If ONT judge the software version number in CurrentSoftwareVersion variable and the software version number in PreviousSoftwareVersion variable inconsistent, then ONT directly enters step S109.
In one embodiment, ONT can indicate new software upgrading failure and rollback extremely this situation of old software generation by sending to the fault code in the fault structure in the TransferComplete request message of ACS to ACS.Such as, fault code can be set to 9800 by ONT, when ACS receives TransferComplete request message and know that fault code is 9800 from TransferComplete request message, can know in the new software upgrading in ONT place failure and rollback to old software.
By the angle from ONT and ACS interactive sessions, the present invention is further described below.
With reference to Fig. 2, first, in step s 201, ONT initiates Openconnection to ACS.Then, in step S202, between ONT and ACS, carry out SSLinitiation.
Then, in step S203, ONT sends Inform request to ACS with HTTP Post form.ACS sends Informresponse to ONT with HTTP response form in step S204.
Then, in step S205, ONT sends HTTP Post (empty) to ACS.ACS sends GetParametervaluesrequest to ONT with HTTP response form in step S206.Then, in step S207, ONT sends GetParameterValues response to ACS with HTTP Post form.
Then, in step S208, ACS checks software version and determines update software bag.Then, in step S209, ACS sends Downloadrequest to ONT with HTTP response form.ONT sends Download response to ACS with HTTP POST form in step S210.
Then, in step S211, ONT starts from ACS download new software and verifies this new software kit, if the image file of new software is legal, stores this new software.Afterwards, ONT performs the step S101 to 104 in above-mentioned Fig. 1.
It is more than the interactive sessions before ONT is restarted between ONT and ACS.
It should be noted that, above-mentioned steps S201 to S210 is existing interactive step in existing protocol, for simplicity's sake, is not described in detail.
Interactive sessions after restarting ONT hereinafter with reference to Fig. 3 between ONT and ACS is described.
First, in step S301, ONT performs the some steps in the step S105-S109 of above-mentioned Fig. 1.Meanwhile, ONT sends Inform request to ACS with HTTP Post form in step s 302.Then, ACS sends Inform response to ONT with HTTP response form in step S303.
Then, in step s 304, ONT sends TransferComplete request to ACS with HTTP Post form.If the fault code in the TransferComplete request that ACS receives is 9800, then can to know in the new software upgrading in ONT place failure and rollback is to old software, so in step S305, ACS can give the alarm.
Then, in step S306, ACS sends TransferComplete response to ONT with HTTP response form.
Then, in step S307, ONT sends HTTP Post (empty) to ACS.ACS sends HTTP response (empty) to ONT in step S308.
Finally, in step S309, ONT initiates Close connection to ACS.
So far, whole flow process terminates.
