Embodiment Construction

[0058] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0059] The present invention provides a kind of ONU upgrading method, it comprises the following steps:

[0060] When the size of the upgrade image file exceeds the maximum allocatable memory size of the OLT for this upgrade, the network management server negotiates with the OLT to determine the size of the image fragments downloaded by the OLT each time, and the image fragments are upgraded by the network management server. It is obtained after splitting, and the size of each image fragment does not exceed the size of the maximum allocable memory.

[0061] The network management server sends a mirror image segment to the OLT each time, and the OLT stores the received image segment in the pre-allocated download space and sends it to the ONU, and then clears the download space until all image segments are delivered.

Abstract

The invention discloses an ONU upgrading method and system, and relates to the technical field of communication. The method comprises the following steps: when the size of the upgrade image file exceeds the size of the maximum memory that can be allocated by the OLT, the network management server negotiates with the OLT to determine the size of the image fragments that the OLT downloads each time, and the image fragments are updated by the network management server to upgrade the image file After splitting, the size of each image fragment does not exceed the size of the maximum allocable memory; each time the network management server sends a mirror image fragment to the OLT, the OLT stores the received image fragment into the pre-allocated download Download the space to the ONU, and then clear the download space until all mirror fragments are delivered. In the present invention, the network management server can automatically and accurately determine the upgrade mode according to the size of the OLT download space, regardless of the size of the upgrade image file, the ONU upgrade can be realized without manual intervention, ensuring the realization of various services.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to an ONU upgrading method and system. Background technique [0002] A passive optical network (Passive Optical Network, PON) system generally includes an optical line terminal (OpticalLine Terminal, OLT), an optical distribution network (Optical Distribution Network, ODN), several optical network units (Optical Network Unit, ONU) or optical network Terminal (Optical network terminal, ONT), unless otherwise specified below, ONU and ONT are collectively referred to as ONU. The OLT is connected to several ONUs respectively through the ODN, the OLT is located on the network side, and the ONU is located on the user side. With the growth of value-added services of operators, ONUs gradually have richer functions in addition to traditional Fiber-To-The-X (FTTX) functions, such as providing smart terminals, smart set-top boxes and other services. As the ONU has more and more functio...
