Embodiment
Core concept of the present invention is: network management system is provided with management object according to default MIB, the MIB management object that sets is issued to the OLT of innings side; OLT directly sends to the MIB management object that receives user side equipment and carries out corresponding processing.Because this MIB is a standard, therefore, can realize between OLT and the user side equipment interconnecting, OLT can directly send to user side equipment with the MIB management object.So, need not, after OLT receives and parses management object, must convert ME to and just can send to user side equipment as prior art.
Be described in further detail below in conjunction with the enforcement of accompanying drawing technical scheme.
As shown in Figure 2, a kind of in the GPON system to the method for user side equipment telemanagement, this method may further comprise the steps:
Here, when network management system adopted the snmp protocol execution to issue processing, the MIB management object was specially SNMP MIB management object.Here the user side equipment of being mentioned can be ONT, also can be ONU.
Wherein, in the step 101, network management system adopts the snmp protocol of standard and the MIB of standard to handle, and SNMP MIB management object is encapsulated in the snmp protocol bag all management objects that need carry out on user side equipment, is issued to OLT.
Accordingly, step 102 is specially:
Step 1021, OLT resolve the snmp protocol bag that receives, and parse the snmp management object; OLT need not SNMP MIB management object is converted to the example of ME, directly with the snmp management object encapsulation to the OMCI frame, and send to the built-in SNMP processing module of user side equipment and carry out corresponding processing.
Here, user side equipment is further resolved the OMCI frame that receives, and carries out corresponding processing according to the SNMP MIB management object that parses.
Here, the SNMP MIB management object at transmitting by the OMCI frame can pre-set a ME who is used to transmit SNMP MIB management object, and can comprise a plurality of ME examples.The set-up mode that is adopted can for: define information such as the attribute that comprises operation in the form of this ME, object identity, attribute length, property value.Also can define the ME of extended formatting, all management objects adopt a ME to manage.It is to be noted: ME is the management object among the GPON, SNMP MIB has a lot of management objects, so, employing pre-sets the mode of a ME, all SNMP MIB management objects are encapsulated in the ME management object, promptly at OLT and user side equipment, such as only needing a ME just much of that between the ONU.The mode of ME is all adopted in contrast, then has how many SNMP MIB management objects or management object group just to need what ME of definition.Thereby, adopt the mode that pre-sets a ME to simplify management process.
Wherein, also comprise two kinds of treatment steps after the step 1021, be respectively:
Step 103a, user side equipment are by its built-in SNMP processing module, after receiving SNMP MIB management object and handle from the OMCI frame, by the OMCI passage, be that the OMCI frame sends an OMCI response message to OLT, after OLT receives this OMCI respond packet,, then continue to handle next SNMP MIB management object if there is not mistake, after the SNMP MIB management object of finishing dealing with all, return a SNMP response message at last and give network management system; Otherwise, no longer handle follow-up SNMPMIB management object, directly will handle the SNMP response message of failure and return network management system.
Step 103b, the management object that need initiatively report network management system is arranged on user side equipment, promptly during snmp trap (TRAP) message, user side equipment is by the OMCI passage, and promptly the OMCI frame changes (AVC) information reporting to OLT with the specific attribute value; The snmp trap message that is assembled into standard by the built-in SNMP processing module of OLT reports network management system.
Here, it is pointed out that the built-in SNMP processing module of OLT and user side equipment is used to parse the packaged content of snmp protocol bag, and parse concrete management object with and value etc.
Here the snmp trap of indication is: the equipment of being managed by a SNMP agency or quilt initiatively sends an information to network management system, and indicating equipment has the generation of an incident, and for example, LOS (dropout) etc. appears in certain light mouth of switch.
The above is preferred embodiment of the present invention only, is not to be used to limit protection scope of the present invention.
