Embodiment 1

[0037] The technical solution of the present invention fully utilizes the function of the OLT to control the PON terminal under the PON system, and controls the image file transmission channel between the PON terminals based on the OLT scheduling, thereby realizing the function of upgrading the image file sharing between the PON terminals. Such as figure 1 As shown, the present invention provides a PON terminal upgrade method based on OLT scheduling, including:

[0038] S1. The OLT sends an upgrade file to the PON, and first upgrades the first PON terminal;

[0039] The OLT can issue an upgrade command to the PON terminal through the OMCI (ONU Management and Control Interface, Optical Network Unit Management Control Interface) / OAM (Operation Administration and Maintenance, Operation, Maintenance and Management) protocol;

[0040] The upgrade file can also include PON terminal type information, and the OLT only upgrades the PON terminal that is consistent with the PON terminal...

Embodiment 2

[0056] Such as figure 2 As shown, the embodiment of the present invention provides a PON terminal upgrade method based on OLT scheduling, including:

[0057] S11. The OLT sends a network-wide upgrade command to all PON terminals:

[0058] When the whole network is upgraded, after receiving the upgrade command from the network management server (or other servers), the OLT sends the whole network upgrade command to all PON terminals through OMCI / OAM;

[0059] S12. OLT scheduling first upgrades several first PON terminals synchronously:

[0060] The OLT issues the upgrade file, first synchronously upgrades the first PON terminal, and in the process of receiving the upgrade file, the first PON terminal replies the received upgrade file fragmentation information to the OLT through the OMCI / OAM protocol or a private command (the embodiment of the present invention) Take the number M of upgrading file fragments as an example);

[0061] S13. The OLT establishes a forwarding packet...

Embodiment 3

[0076] Such as image 3 As shown, the overall solution process for upgrading is as follows:

[0077] S101, the OLT sends the upgrade command to all PON terminals under the OLT:

[0078] When the whole network is upgraded, the OLT obtains the upgrade command and the upgrade file, sends the upgrade command to all PON terminals under the OLT, and informs that the upgrade is about to start.

[0079] S102. The OLT randomly selects and upgrades several first PON terminals:

[0080] The OLT randomly selects some PON terminals and sends the upgrade file fragments synchronously. These PON terminals are referred to as the first PON terminal here, which means the PON terminal that has obtained the upgrade file fragments. The first PON terminal will be described later and is not limited to the first PON terminal from the OLT. The upgrade file fragments obtained in a batch are also upgrade file fragments obtained from other PON terminals.

[0081] S103. The OLT controls the first PON te...

Abstract

The invention discloses a PON terminal upgrading method based on OLT scheduling. The PON terminal upgrading method comprises the following steps: an OLT issues an upgrading file to a PON and upgradesa first PON terminal; the OLT receives the upgrading file information received by each first PON terminal; the OLT enables the one or more first PON terminals to send the upgrading files received by the first PON terminals to other one or more second PON terminals which do not receive the upgrading files received by the first PON terminals according to the received upgrading file information received by the first PON terminals; enabling the second PON terminals to receive the upgrading files sent by the one or more first PON terminals, and upgrading the second PON terminals according to the upgrading files; and classifying the second PON terminals as the first PON terminals, and repeating the steps by the OLT to enable each PON terminal to send the upgrading file received by the PON terminal to other PON terminals which do not receive the upgrading file received by the PON terminal until the upgrading of all PON terminals is completed. The invention further provides corresponding OLT equipment and a corresponding OLT system.

Description

technical field [0001] The present invention belongs to the technical field of PON, and more specifically relates to a PON terminal upgrade method, system and OLT equipment based on OLT scheduling. Background technique [0002] With the diversification of functions and applications of PON terminals and changes in networking, there will inevitably be some engineering problems. At the same time, the functions and requirements of PON (Passive Optical Network, passive optical The PON terminal version needs to be continuously iterated. At present, the network-wide upgrade of PON terminal version is generally realized through remote upgrade, which is used to solve engineering problems or add new requirements and functions. Therefore, a reliable, efficient and fast remote upgrade method is particularly important. There are two general upgrade methods available, as follows: [0003] The first method: remotely call the upgrade interface through the tr069 platform. Gateway upgrades...
