The GPON (Gigabit-Capable PON) technology is the latest generation of passive optical integrated access standard based on ITU-T G.984.x and ITU-T G.988 standards. The GPON uses the Generic Framing Procedure (GFP) technology defined by ITU-T at the second layer for reference, and extends and supports the gem (general encapsulation methods) encapsulation format, and service of any type and any rate is recombined and transmitted by a PON (Passive optical network), and the GFM frame header contains the frame length indication byte, which can be used for the transmission of variable length data packets, and improves the transmission efficiency, so that it can support the whole service more simply, universally and efficiently.
A PON system in the prior art is composed of an Optical Line Terminal (OLT) installed in a central control station, an Optical Distribution Network (ODN), and a plurality of Optical Network Units (ONUs) installed in user sites. At present, both OLT and ONU in the GPON communication field mainly adopt protocols such as ITU-T G.984.4 and ITU-T G.988, etc., the protocols stipulate an ONU management control interface, MIB, messages and related protocols under a GEM mode, and ME for reporting ONU ME (Managed Entity) support capability is defined; ME described by OMCI (ONU Management and Control Interface) capability, ME described by ME capability and ME described by attribute capability.
In practical application, each OLT manufacturer, from a commercial perspective, often adds some private extended OMCI MEs when each OLT and its own ONU are docked, so as to implement a certain extended specific function, thereby increasing the competitiveness of its own product, and since the ONU of a different manufacturer does not know how the extended OMCI of the OLT to be docked is defined, when the OLT is docked, the problem of offline of the ONU due to the fact that the OLT is not docked occurs, thereby limiting the docking between the ONU of a different manufacturer and the OLT.
For the above problems, it is a common practice at present to specifically modify an ONU with respect to a specific extended OMCI ME, which causes the ONU to frequently update its version, which is cumbersome and increases the difficulty of maintenance.
In view of this, it is necessary to provide a method and a system for enabling an optical network unit to be compatible with private OMCI ME of optical line terminals of different manufacturers, so as to achieve the interface between the optical network unit and the optical line terminal.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood by those skilled in the art, the present invention is further described with reference to the accompanying drawings and examples.
The invention OMCI: ONU Management and Control Interface as ONU Management Control Interface; ME: managed Entity; CLASS: class, which is essentially a data type.
Fig. 1 shows a schematic flow chart of an embodiment of a method for implementing the docking of an optical network unit and an optical line terminal according to the present invention. As shown in fig. 1, the method includes:
s101, the optical network unit stores the supported OMCI ME in an instance pool.
In this step, the onu creates an instance pool, and stores the processing function that has previously processed the extended OMCI ME of each butted olt, that is, the supported OMCI ME CLASS and the corresponding processing function, in the instance pool, and each OMCI ME instance in this embodiment is uniquely identified by an ID.
S102, the optical network unit creates a universal extension function for processing the private OMCI ME in the optical line terminal.
In this step, the generic extension function is mainly used to receive the private OMCI message from the optical line terminal, parse the message, and then respond accordingly. For the optical network unit, it is not necessary to know what the private OMCI needs to do specifically, so the universal extension function receives the private OMCI message from the optical line terminal, and after parsing the message, returns a signal to the optical line terminal, where the signal indicates that there is a function in the optical network unit that processes the private OMCI message from the optical line terminal, and the optical network unit may be docked with the optical line terminal. Since the generic extension function does not process the private OMCI message from the optical line termination, but only returns a signal to the optical line termination, different private OMCI messages can share the generic extension function.
S103, after receiving the OMCI ME CLASS sent by the optical line terminal, the optical network unit analyzes the received OMCI ME CLASS to obtain OMCI ME CLASS ID.
Since each OMCI ME instance stored in the instance pool is uniquely identified by an ID, the ID of the received OMCI ME CLASS needs to be extracted for a search query in the instance pool.
S104, the optical network unit searches whether a processing function corresponding to the OMCI ME CLASS ID is stored in an instance pool or not according to the obtained OMCI ME CLASS ID, and executes the step S105 when the processing function corresponding to the OMCI ME CLASS ID is not stored in the instance pool; when the processing function corresponding to the OMCI ME CLASS ID is stored in the instance pool, step S106 is executed.
In this step, a search is performed in the instance pool according to the received OMCI ME CLASS ID, and if a processing function corresponding to the OMCI ME CLASS ID is searched in the instance pool, which indicates that the received OMCI ME CLASS is supportable by the optical network unit, the processing function is called to process the received OMCI ME CLASS at this time; if no processing function corresponding to the OMCI ME CLASS ID is retrieved in the instance pool, a generic extension function is called to process the received OMCI ME CLASS.
And S105, the optical network unit calls a general extension function to process OMCI ME CLASS corresponding to the obtained OMCI ME CLASS ID.
And S106, the optical network unit calls the corresponding processing function retrieved from the instance pool to process the OMCI ME CLASS corresponding to the obtained OMCI ME CLASS ID.
Fig. 2 shows a block diagram of an embodiment of a system 10 for interfacing an optical network unit with an optical line terminal according to the present invention. As shown in fig. 2, the system 10 includes a first docking subsystem 111 located in the optical network unit 11, where the first docking subsystem 111 located in the optical network unit 11 is configured to: the OMCI ME already supported in the optical network unit 11 is saved in its instance pool. A generic extension function for handling proprietary OMCI ME in the optical line terminal 12 is created. Understandably, in the present embodiment, the first docking subsystem 111 located in the optical network unit 11 stores the processing function of the extended OMCI ME that has previously processed each docked optical line terminal 12 correspondingly before the optical network unit 11, that is, the supported OMCI ME CLASS and the corresponding processing function thereof, in the created instance pool, and each OMCI ME instance in the present embodiment is uniquely identified by an ID. And the created general expansion function is mainly used for receiving the private OMCI message from the optical line terminal 12 and analyzing the message, and only needs to return a signal indicating that the optical network unit 11 can be docked with the optical line terminal 12 after receiving the message without performing corresponding processing on the received private OMCI message, so that the received private OMCI message is not required to be correspondingly processed.
In some embodiments, for example, in this embodiment, the system 10 for implementing the optical network unit to interface with the optical line terminal further includes a second docking subsystem 121 located in the optical line terminal 12, and the first docking subsystem 111 located in the optical network unit 11 is further configured to: after receiving the OMCI ME CLASS sent by the second docking subsystem 121 located in the optical line terminal 12, the received OMCI ME CLASS is parsed to obtain OMCI ME CLASS ID. Retrieving whether a processing function corresponding to the OMCI ME CLASS ID is stored in an instance pool or not according to the obtained OMCI ME CLASS ID, and calling a universal extension function to process OMCI ME CLASS corresponding to the obtained OMCI ME CLASS ID when the processing function corresponding to the OMCI ME CLASS ID is not stored in the instance pool; and when the processing function corresponding to the OMCI ME CLASS ID is stored in the retrieved instance pool, calling the corresponding processing function retrieved from the instance pool to process the OMCIME CLASS corresponding to the obtained OMCI ME CLASS ID.
In summary, the invention stores the OMCI ME supported in the onu in an instance pool, and creates a universal extension function for processing the private OMCI ME in the olt, where the universal extension function can handle various basic extended OMCI messages of various olt manufacturers, and the onu does not need to add each extended OMCI ME separately, and does not need to update the software version of the onu once every extended OMCI ME is added, so that the docking process is simple, and the onu can be compatible with the private OMCI MEs of olt of different manufacturers, and the onu of different manufacturers can be docked with the olt.
