Embodiment 1

[0042] Embodiment 1, a method for automatically upgrading a communication device, comprising:

[0043] Request to the network side to download the required system files;

[0044] Check the system file according to the file verification information carried in the downloaded system file, if the file verification information is consistent with the requested system file, then the verification is passed; the file verification information includes at least Information indicating the file type and / or device model of the system file;

[0045] After the verification is passed, replace the original corresponding system file with the system file.

[0046] In this embodiment, the file check information may be, but not limited to, placed at the beginning of the system file, for example, it may be placed at the same position as the original CRC check code.

[0047] In this embodiment, the step of verifying the system file according to the file verification information carried in the downl...

Embodiment 2

[0086] Embodiment 2, an automatic upgrade device for communication equipment, including:

[0087] The download module is used to request the network side to download the required system files;

[0088] A verification module, configured to verify the system file according to the file verification information carried in the downloaded system file, and pass the verification if the file verification information matches the requested system file; the file verification The verification information at least includes information indicating the file type and / or device model of the system file;

[0089] The upgrade module is used to replace the original corresponding system file with the system file after the verification is passed.

[0090] In this embodiment, when the file verification information includes information indicating the file type of the system file, the verification module verifies the system file according to the file verification information carried in the downloaded s...

Abstract

The invention discloses an automatic upgrading method and an automatic upgrading device of communication equipment. The method comprises the following steps of: requiring a network side for downloading a required system file; verifying the system file according to file verification information carried in the downloaded system file and determining that verification passes if the file verification information is consistent with a requested system file, wherein the file verification information at least comprises information for indicating the file type and / or equipment model of the system file; and after the verification passes, replacing an original corresponding system file by the system file. Through the technical scheme, the correctness and completeness of a file downloaded during automatic upgrading of the communication equipment can be ensured, file type errors or equipment model errors can be avoided, and the situation of unavailable startup of the equipment after automatic upgrading due to a file error is avoided.

Description

technical field [0001] The invention relates to the communication field, in particular to an automatic upgrading method and device for communication equipment. Background technique [0002] Automatic upgrade is a basic function of most communication devices (such as switches, routers, etc.). Usually, for a certain communication device, automatic upgrade may need to download many different types of files, such as system image files, bootrom files, configuration files, and the like. Once the device downloads the wrong file, it will cause the device to fail to start. [0003] At present, most communication devices generate a CRC check code during file generation and check the CRC check code before or after downloading to avoid file content errors caused by file damage or transmission errors. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide an automatic upgrade method and device for communication equipment, which ca...
