[0015] 2) There are restrictions on the intercommunication between OLT and ONU of different manufacturers. Even if both sides of the intercommunication have defined standardized OAM or OMCI interface standards, ONUs managed based on specific models must first be recognized by the OLT and NMS before they can be successfully connected. This does not meet the requirements of operators or users for convenient network access of terminal equipment

Embodiment Construction

[0035] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0036] First, the concept of ONU management in some PON systems is described as follows.

[0037] Regarding the creation mode of the ONU management model, there are usually two modes at present, that is, manual addition and automatic discovery.

[0038] The management model of manually adding ONUs is specified from top to bottom by the NMS or OLT. This method is mostly used in ONU offline configuration management occasions. At present, it is generally used to manually input information such as the ONU authentication logo, ONU equipment model (referred to as the ONU model), and configuration in advance to create an ONU authorization entry corresponding to the ONU equipment model. When the ONU matching the device model goes online, the corresponding authorization and configuration information can be obtained through the ONU authorization information table sto...

Abstract

The invention relates to a method and a system for managing optical network units (ONU) based on an interface capability set. The method comprises the following steps of: dividing the ONU with the same interface capability to the same ONU interface capability set, and regarding the ONU as the same class of ONU for configuration management; establishing 'ONU interface capability set templates' of the ONU as ONU management models on an optical line terminal (OLT) and a network management system (NMS), and configuring the ONU management models by adopting standard administration and maintenance (OAM) or simple network management protocols (SNMP), so that the ONU can be accessed to a network and incorporated to management of an established passive optical network (PON) system. By the method and the system, on the premise that software of the OLT or the NMS is not required to be upgraded, the ONU type supported in the PON system can be flexibly expanded, the ONU based on ONU equipment type management can be compatible, the ONU based on the ONU interface capability set management is supported at the same time, the PON system can easily support and manage the 'newly developed or expanded' ONU, and the ONU produced by different factories can be plugged and played in the network.

Description

technical field [0001] The present invention relates to a management method for an optical network unit (ONU) connected to it by an optical line terminal (OLT) in the field of a passive optical network (PON), specifically a method and system for managing an ONU based on an interface capability set . In particular, it refers to a method and a system for managing an ONU based on an ONU interface capability set. Background technique [0002] The PON system is a point-to-multipoint access network device based on a passive optical communication mechanism. The early PON technology used time-division multiplexing technology to complete point-to-multipoint communication, while other multiplexing technologies, such as wavelength division multiplexing and The code division multiple access technology is also being explored in the application of the PON system, but it has not been widely used yet. [0003] Taking the traditional PON system based on time-division multiplexing technolog...
