Problems solved by technology

[0004] In the process of realizing the present invention, the inventor found that there are at least the following problems in the prior art: due to the difference in communication protocols between the BNG and the OLT, and between the OLT and the ONU, when the BNG manages the ONU, there is a problem between the BNG and the OLT. Messages encapsulated with ANCP protocol need to be modified to messages encapsulated with OMCI protocol between OLT and ONU
Therefore, this has caused the problem of inflexible management of the ONU

Abstract

The embodiment of the invention discloses a management method and a system of a passive optical network as well as an optical line terminal, relating to the technical field of communication. The embodiment of the invention is invented for the flexible management of an optical network unit. The above method comprises: the optical line terminal receives a message sent by a gateway of a broadband network, and the message comprises parameter configuration information packaged by an access node control protocol; the optical line terminal extracts the parameter configuration information packaged by the access node control protocol from the message; the optical line terminal packages the parameter configuration information packaged by the access node control protocol, the passive optical network transmission and collection layer information and the passive optical network physical layer information into a downlink frame to be sent to the optical network unit. The embodiment of the invention is mainly applied to the passive optical network access technology.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a management method and system of a passive optical network, and an optical line terminal. Background technique [0002] Such as figure 1 As shown, the traditional access aggregation network mainly includes: UE (User Equipment, user equipment), RG (Residential Gateway, home gateway), AN (Access Node, access node), BNG (Broadband Network Gateway, broadband network gateway) and other equipment. Among them, the user equipment UE is a terminal device that provides users with access to various service functions, such as a PC that provides Internet access services, a multimedia phone that provides video communication services, and a set-top box (STB, Set Top Box) that provides IPTV services. The home gateway RG is interconnected with the user equipment UE to form a home network, and the RG is connected to the AN through an access line. AN provides various access methods for RG...
