[0060] Such as figure 2 Shown is the flow chart of the first embodiment of the method of the present invention, comprising the following steps:

[0061] S201: The OLT determines a list of ONUs that can perform version upgrades at the same time;

[0062] Because the ONUs under the main optical fiber of the OLT are generally of the same or similar type, for example, the ONUs deployed to the residential area are basically connected to the FTTH type ONUs, and the ODNs connected to the enterprise park are basically connected to the FTTB type. Because the ONUs of the same type or close to each other use the same software version file, the OLT first classifies the subordinate ONUs before upgrading the version of its subordinate ONUs, that is, determines the list of ONUs that can perform version upgrades at the same time. The preferred method is as follows:

[0063] The OLT first searches for the ONU with the same version file in its subordinate ONUs and marks them; then checks the...

Abstract

The invention relates to a method and a system for upgrading software versions of a passive optical network unit (ONU) in batch. The method comprises the following steps of: determining ONU lists capable of simultaneously performing version upgrade by an optical line terminal (OLT); establishing a multicast channel for version upgrade for ONU in the ONU lists; and downloading the upgraded version files to the ONU in the ONU lists through the multicast channel. The method and the system not only improve the downloading rate of the upgraded version files, but also simplify the management.

Description

technical field [0001] The present invention relates to the field of software version upgrades of communication equipment, in particular to a method and system for upgrading software versions of optical network units (OpticalNetwork Units, ONUs) in Gigabit-capable Passive Optical Networks (GPON) in batches. Background technique [0002] GPON is a point-to-multipoint network system, and its network element equipment includes: optical line terminal (OpticalLine Terminal, OLT), passive optical network unit (Optical Network Unit, ONU) and passive optical network terminal (Optical Network Termination , ONT). Among them, the OLT is the central office side equipment, the ONU and the ONT are the user side equipment, the OLT and the ONU / ONT are connected by an Optical Distribution Network (ODN), the ONU provides a direct or remote user side interface, and the ONT is the user side interface. ONU for FTTH (Fiber To The Home) with user port function. "ONU" is used herein to represent ...
