Technical field

The embodiments of the present invention relate to communication technologies, and in particular, to an upgrade method, device, and access network in an access network.

Background technique

At present, the upgrade of the optical network terminal (the optical network terminal) is controlled by the element management system (EMS). The main process of the upgrade is to report the version number to the ONT. After the NMS receives the version number of each ONT, the NMS compares the version number of each OTN with the version number set by the OTN in the NMS, and adds the OTN IDs with different version numbers to the load (upgrade) list. To upgrade the version of the OTN, and then send the load list to the optical line terminal (Optical Line Terminal; OLT). If the OLT first upgrades the version of the ONT corresponding to the identifier of the ONT in the load list, Then, the file file of the ONT is obtained from the network management system by using a file transfer protocol (File Transfer Protocol; the file name: FTP), and the program file is stored in the passive optical network (Passive Optical Network; PON) board of the OLT. If the version of the ONT is upgraded for the first time, you can obtain the version of the ONT upgrade from the Flash in the PON card. program files. After the OLT obtains the program file of the ONT, it notifies the ONT to trigger the OTN to initiate a load request to the OLT, and the OLT can pass the acquired program file of the ONT to the ONT according to the load request. The ONT Management and Control Interface (OMI) or Operation Administration and Maintenance (OAM) is sent to the ONT to upgrade the ONT.

Since the OLT upgrades the ONT mainly by serial upgrade, it takes a long time to upgrade the ONT of the whole frame, which cannot meet the large-scale commercial efficiency. In addition, the OLT currently uses OMCI/OAM to transfer the program files to the ONT, due to OMCI. The /OAM protocol channel must control the forwarding of program files through the OLT's central processing unit (Central Processing Unit; CPU: CPU), and the OMCI/OAM transmission rate is relatively low, so it has a greater impact on the OLT CPU processing performance. At the same time, the transmission time is too long, which also makes the upgrade performance difficult to meet large-scale commercial use.
