[0048] Such as figure 2Shown is the flow chart of the first embodiment of the method of the present invention, comprising the following steps:

[0049] S201: Download the ONU upgrade version file to the OLT;

[0050] In the present invention, the ONU upgrade version files are downloaded to the OLT through the File Transfer Protocol (File Transfer Protocol, FTP).

[0051] S202: The OLT configures each subordinate ONU configuration according to the user to automatically upgrade online and whether to restart after the upgrade is successful;

[0052] S203: Find a matching upgrade version file in the upgrade version file downloaded above for the online ONU that is configured to be automatically upgraded when it goes online;

[0053] For ONUs that are configured to be automatically upgraded when they go online but are currently offline, the firmware version upgrade process does not process them, and wait for the ONUs to go online before performing firmware version upgrades.

[0055] Such as image 3 Shown is the flow chart of the second embodiment of the method of the present invention, comprising the following steps:

[0056] S301: Download the ONU upgrade version file to the OLT;

[0057] S302: The OLT configures each subordinate ONU configuration according to the user to automatically upgrade online and whether to restart after the upgrade is successful;

[0058] S303: Obtain the attribute information of the current ONU, the above attribute information at least includes the current version number, manufacturer identification and chip type of the current ONU;

[0059] S304: In the upgraded version file downloaded, search for the upgraded version file whose manufacturer's identification and chip type are the same as the manufacturer's identification and chip type of the current ONU, if found, then execute S305; otherwise, the current ONU firmware version upgrade is completed, and execute S314;

Abstract

The invention relates to an automatic upgrading method and system of firmware version of an optical network unit (ONU). In the method, after ONU upgrading version documents are downloaded to an optical line terminal (OLT), the OLT transmits the upgrading version documents to the corresponding ONU through an Ethernet frame; and the automatic upgrading system comprises a webmaster server (EMS), the OLT and the ONU. The real time and the efficiency of the upgrading of the ONU firmware version are excellently improved and the intelligentized processing of the upgrading of the firmware version is realized.

Description

technical field [0001] The present invention relates to an Ethernet passive optical network (Ethernet Passive Optical Network, EPON), in particular to an optical network unit (Optical Network Unit, ONU) firmware version automatic upgrade method and system. Background technique [0002] In the EPON operation network, the common ONU firmware version upgrade system such as figure 1 As shown, the system includes a network management server (EMS) 100, an optical line terminal (optical line terminal, OLT) 200, and several ONUs (the maximum number is 32) 300, and the transmission direction from the OLT to the ONU is the downstream direction (downstream) , the transmission direction from the ONU to the OLT is the upstream direction (upstream). [0003] The OLT and ONU support the ONU firmware version upgrade function based on the OAM (Operations, Administration and Maintenance) message mechanism. The ONU upgrade version file should include the configuration file and the cyclic redu...
