Abstract
The invention relates to a method for realizing compatible docking between an ONU (Optical Network Unit) and an OLT (Optical Line Terminal) in a GPON (Gigabit Passive Optical Network) system. The method is characterized by comprising the following steps that: the OLT sends an OMCI (ONU Management and Control Interface) message firstly to set an OLT Vendor ID attribute of an ONU management entity (ME) OLT-G before issuing a configuration service to the ONU through the OMCI; the ONU judges the type of the OLT according to the content of the received OLT Vendor ID attribute; initialization of MEs is performed according to a plurality of private MEs which are required by the OLT and supported by the ONU; and information corresponding to the OLT is acquired according to an OLT Vendor to be issued. Through adoption of the method, compatible matching between the OLT and the ONU is realized; one ONU can be matched with all OLTs; and service configuration can be performed correctly. The method is economical and convenient, and has very high application value and a wide market range.

It is preferred that described step (2) comprise the following steps that：
(2.1) OLT described in before configuration service is issued to ONU by OMCI sent to include to described ONU and is somebody's turn to do
The OMCI message of OTL Vendor ID attributes；
(2.2) ONU described in receives the message, and according to the OLT Vendor ID attributes initialization management for wherein including
Entity ME, and the information according to corresponding to the OLT Vender ID attributes obtain the OLT Vendor issues feature, to complete this
The compatible docking of ONU and OLT in GPON systems.
More preferably, there is a step before described step (2.1)：
(2.1.0) ONU and OLT described in carries out PLOAM registrations.
More preferably, described step (2.2) specifically includes situations below：
(2.2.1) the OLT Vendor described in include a management entity ME, and described ONU is according to described OLT
Vendor ID attributes initialize a management entity ME of the ONU, and should according to described OLT Vendor ID attributes acquisition
The corresponding OLT information of OLT Vendor issues feature, to complete the compatible docking of ONU and OLT in the GPON systems；
(2.2.2) the OLT Vendor described in include multiple management entity ME, and described ONU is according to each
OLT Vendor create and initialize the management entity ME of corresponding number, and are obtained according to described OLT Vendor ID attributes
The corresponding OLT information of the OLT Vendor issues feature, to complete the compatible docking of ONU and OLT in the GPON systems.
Method using ONU docking compatible with OLT are realized in the GPON systems, as described OLT issues OMCI information
OLT Vendor ID are set, and allow described ONU its management entity ME to be initialized according to the OLT Vendor ID, make the ONU's
Management entity ME is matched with the OLT Vendor ID, and when the OLT Vendor ID have multiple privately owned management entity ME,
Described ONU creates and initializes corresponding management entity ME also according to the multiple privately owned management entity ME of the OLT Vendor,
The OLT information that the OLT Vendor are obtained according to the OLT Vendor ID again issues feature, issues feature according to the information and completes
ONU docking compatible with OLT, realize the quickening of the business configuration speed of ONU and OLT in GPON systems, and an ONU version
The OLT of all versions is compatible with, and can correctly carry out business configuration, with very big using value and extensive market
Scope.
Description of the drawings
Fig. 1 be the present invention GPON systems in realize ONU docking compatible with OLT method program flow diagram.
Specific embodiment
In order to be more clearly understood that the technology contents of the present invention, describe in detail especially exemplified by following examples.
The method for realizing ONU docking compatible with OLT in the GPON systems, which is mainly characterized by, described method include with
Lower step：
(1) OLT described in is docked with described ONU；
(2) OLT described in carries out compatible debugging with described ONU, completes compatible docking.
Described step (2) comprise the following steps that：
(2.1) OLT described in before configuration service is issued to ONU by OMCI sent to include to described ONU and is somebody's turn to do
The OMCI message of OTL Vendor ID attributes；
(2.2) ONU described in receives the message, and according to the OLT Vendor ID attributes initialization management for wherein including
Entity ME, and the information according to corresponding to the OLT Vender ID attributes obtain the OLT Vendor issues feature, to complete this
The compatible docking of ONU and OLT in GPON systems.
There is a step before described step (2.1)：
(2.1.0) ONU and OLT described in carries out PLOAM registrations.
Described step (2.2) specifically includes situations below：
(2.2.1) the OLT Vendor described in include a management entity ME, and described ONU is according to described OLT
Vendor ID attributes initialize a management entity ME of the ONU, and should according to described OLT Vendor ID attributes acquisition
The corresponding OLT information of OLT Vendor issues feature, to complete the compatible docking of ONU and OLT in the GPON systems；
(2.2.2) the OLT Vendor described in include multiple management entity ME, and described ONU is according to each

Vendor has many privately owned management entity ME, then is also created according to Vendor in the lump and initializes multiple management entity ME, so
Afterwards according to the sending down service feature of the OLT of the producer come the configuration of finishing service.
A kind of method specific embodiment of GPON ONU docking compatible with OLT is as follows：
(1) EPON GPON is based on, described ONU and OLT completes PLOAM registrations；
(2) the OMCI message comprising its Vendor ID is sent to described ONU by OLT；
(3) ONU described in initializes the management entity ME of oneself according to the Vendor ID of OLT, if the OLT
Vendor has multiple privately owned management entity ME, then described ONU is also created according to the Vendor in the lump and initialized multiple management
Entity ME, then according to the sending down service feature of the OLT of the producer come the configuration of finishing service.
In a kind of specific embodiment, OLT arranges ONU management entity ME OLT-G OLT's by issuing OMCI information
Vendor ID this attribute, the OLT that ONU judges to be which producer according to the value of the OLT Vendor ID for arranging, so as to come
Compatible docking is carried out according to the sending down service feature of the OLT of the producer.
Method using ONU docking compatible with OLT are realized in the GPON systems, as described OLT issues OMCI information
OLT Vendor ID are set, and allow described ONU its management entity ME to be initialized according to the OLT Vendor ID, make the ONU's
Management entity ME is matched with the OLT Vendor ID, and when the OLT Vendor ID have multiple privately owned management entity ME,
Described ONU creates and initializes corresponding management entity ME also according to the multiple privately owned management entity ME of the OLT Vendor,
The OLT information that the OLT Vendor are obtained according to the OLT Vendor ID again issues feature, issues feature according to the information and completes
ONU docking compatible with OLT, realize the quickening of the business configuration speed of ONU and OLT in GPON systems, and an ONU version
The OLT of all versions is compatible with, and can correctly carry out business configuration, with very big using value and extensive market
