Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making all other embodiment that obtain under creative work prerequisite, belong to the scope of protection of the invention.

The technical scheme that the embodiment of the present invention provides is applied to passive optical network, in embodiments of the present invention, as shown in Figure 2, passive optical network comprises residence network guard system and PON (Passive Optical Network, passive optical-fiber network), wherein, PON at least comprises OLT (Optical Line Terminal, optical line terminal) and ONU (Optical Network Unit, optical network unit), OLT comprises at least one group of first line of a couplet port set, and first line of a couplet port set is used for connecting operator and OLT.Telecom operators are connected by first line of a couplet port set with OLT, and OLT and ONU are connected by ODN (Optical Distribution Network Unit, fiber distribution net).Wherein ODN is the fiber distribution network being comprised of POS (Passive Optical Splitter, passive fiber splitter).Residence network guard system is connected with OLT, and management and supervision said system, thereby realizes the data interaction between operator and ONU.Wherein, the particular user terminal that ONU side connects can be landline telephone, FE (Fast Ethernet) etc.In addition, PON in the present invention comprises GPON (Gigabit-Capable Passive Optical Network, gigabit passive optical network), EPON (Ethernet Passive Optical Network, ethernet passive optical network), 10G EPON (10G ethernet passive optical network) and WDM PON (Wavelength Division Multiplexing Passive Optical Network, Wave division multiplexing passive optical network) etc., here do not limit.

The embodiment of the present invention provides a kind of method of shared EPON, as shown in Figure 3, comprising:

101, described residence network guard system is determined the operator that described ONU is corresponding, and in the communication protocol stack between described OLT and described ONU, adds operator's sign of the operator that described ONU is corresponding.

Wherein, residence network guard system is determined the operator that OLT is corresponding with communication protocol stack between ONU, in specific implementation process, can in communication protocol stack, increase extended byte, extended byte is used for identifying operator, and extended byte can be digital, alphabetical or other can play the character string of mark action.Optionally, can enable byte by increasing, by residence network guard system, by detection, enable byte and determine whether enabling extended byte, enable byte and whether enable extended byte for sign.For example: in EPON/GPON, can in lead code, increase the extended byte of sign operator, and in lead code, EXTEND byte is set, for setting, whether enable extended byte.When residence network guard system setting EXTEND is TRUE, under PON system, OLT and ONU all enable for identifying the extended byte of operator.

Wherein, determine the operator that ONU is corresponding, can load operator's sign for all ONU, operator's sign, for distinguishing different operators, makes the corresponding Yi Ge of ONU operator, and Er Yige operator can corresponding one or more ONU.In addition, in this programme, by OLT, carry with operator and identify corresponding data with communication protocol stack between ONU, make to carry out between operator and ONU data interaction.

102, described residence network guard system is set up the first mapping relations and the second mapping relations.

Wherein, the first mapping relations are the mapping relations of operator's sign and first line of a couplet port set, and first line of a couplet port set at least comprises a first line of a couplet port, different business corresponding to first line of a couplet port.Residence network guard system is processed according to the business game of operator, selects business to be forwarded to certain corresponding concrete first line of a couplet port.The second mapping relations are the mapping relations of operator's sign and ONU, and operator's sign is used for distinguishing operator.

Wherein, for operator increases operator's sign, and the pre-set first line of a couplet port set by being linked to each operator on OLT equipment, can obtain the first mapping relations.For example: the operator of first operator is designated operator 1, corresponding first line of a couplet port set is first line of a couplet port set 1; The operator of second operator is designated operator 2, and corresponding first line of a couplet port set is first line of a couplet port set 2; The operator of San Ge operator is designated operator 3, and corresponding first line of a couplet port set is first line of a couplet port set 3.The operator's sign obtaining is as shown in table 1 with the mapping relations table that first line of a couplet port set forms.

Table 1

Operator's sign	First line of a couplet port set
		Operator 1	First line of a couplet port set 1
Operator 2	First line of a couplet port set 2
		Operator 3	First line of a couplet port set 3
…	…

As shown in table 1, operator's sign forms relation one to one with first line of a couplet port set, and the mapping relations of known first line of a couplet port set and operator's sign and first line of a couplet port set just can obtain the operator sign corresponding with this first line of a couplet port set.

Wherein, in the time of can activating the service the user corresponding with ONU, input ONU identifies for this ONU loads operator.Can or number expand by the sign in PON, thereby load operator's sign.For example: can expand the LLID in EPON (logic ID); Can expand the SN in GPON (product ID) number; Also can expand other signs of PON, not limit here.

Wherein, the hardware resource of ONU numbering and software resource numbering all can be used as ONU sign, are used for distinguishing ONU.Wherein, the hardware resource of ONU numbering can be ONU dispatch from the factory title or numbering, and the software resource numbering of ONU is by obtaining ONU Custom Number.All ONU are loaded to operator's sign, just obtain the mapping relations of ONU sign and operator's sign, i.e. the second mapping relations.For example: 4 hardware resources corresponding to ONU are numbered ONU1-ONU4, corresponding software resource is numbered ONU (1)-ONU (4).The hardware resource of First ONU is numbered ONU1, and software resource is numbered ONU (1), and the operator of loading is designated operator 1; The hardware resource of second ONU is numbered ONU2, and software resource is numbered ONU (2), and the operator of loading is designated operator 3; The hardware resource of the 3rd ONU is numbered ONU3, and software resource is numbered ONU (3), and the operator of loading is designated operator 2; The hardware resource of the 4th ONU is numbered ONU4, and software resource is numbered ONU (4), and the operator of loading is designated operator 2.The ONU sign obtaining is as shown in table 2 with the mapping relations table of operator's sign formation.

Table 2

As shown in table 2, the corresponding Yi Ge of ONU operator, Er Yige operator can corresponding one or more ONU, and hardware resource numbering and software resource are numbered and all can be identified ONU.Known ONU sign, the known operator corresponding with this ONU of mapping relations table forming according to the second mapping relations.

In addition, in PON system, start after expansion operator sign, residence network guard system is set operator's sign, because operator's sign is corresponding one by one with operator, each operation commercial city has management system separately, so can define according to operator's quantity of setting the quantity of operator's management system.Wherein, the large I of operator's management system decides according to the number of ONU corresponding to each operator, do not need to allocate in advance, and the ODN between OLT and ONU shares.

103, described residence network guard system is according to the first mapping relations and the second mapping relations, and utilizes the communication protocol stack between described OLT and described ONU, between described operator and described ONU, carries out data interaction.

Wherein, between operator and ONU, carry out mutual data and comprise upstream data and downlink data.Between operator and ONU, there is OLT, while carrying out data interaction between operator and ONU, will transmit data by OLT.Wherein, between OLT and ONU by by Deta bearer in having on the communication protocol stack of operator sign, thereby carry out the data interaction between OLT and ONU.

Concrete, the data that CongONUDao operator transmits are upstream data.Residence network guard system is according to the second mapping relations, judge the operator sign corresponding with ONU, again according to the first mapping relations, judgement Yu Gai operator identifies corresponding first line of a couplet port set, and give this first line of a couplet port set by data retransmission, thereby transfer data to this operator, identify corresponding operator.Operator can only receive the ONU information relevant to self, and does not receive the information of the ONU of other operators.

The data that transmit from operator to ONU are downlink data, obtain the first line of a couplet port set being connected with operator.Afterwards data are transmitted to OLT by first line of a couplet port set by operator, when data are transmitted to ONU from OLT, by Deta bearer in communication protocol stack, and utilize the second mapping relations, send the data to operator and identify corresponding ONU, when ONU receives data, by ONU, identify and determine that again reception and this ONU identify the data of corresponding ONU.For the corresponding a plurality of ONU of Yi Ge operator, ONU obtains the scheme of the data of oneself, and prior art is comparatively ripe, at this, no longer carefully states.ONU can only receive the data that the operator corresponding with self transmits, and does not receive the data that other operators transmit.

For example: in table 2, ONU3 and ONU4 are used by the user of operator 2, system renumbers the self-defined ONU that issues operator 2 into the numbering ONU in the virtual system of operator 2 (3) and ONU (4), and by virtual resource real-time report to operator 2, and the ONU of other operators resource can not be seen by operator 2.

In addition, residence network guard system has highest weight limit scope, all OLT and hardware and the self-defining resource of ONU in can management and supervision PON, and manage mapping relations table.Carrier side can be managed OLT first line of a couplet port, ONU, the ONU port that Yu Ben operator is relevant, and the resource such as related service priority.Such as: operator 1, on can managing in PON system, be linked to the resources such as priority policy that ONU, ONU port resource, this operator of user's side of first line of a couplet port resource that operator 1 is relevant, operator 1 can arrange and scheduling strategy.

Wherein, the configuration of data transfer path is first to carry out software configuration, then is converted into hardware configuration.Wherein, software configuration is the self-defined configuration that residence network guard system carries out the port of transfer of data.For example: the transmission of software configuration data is from the port a of ONU (1), to be sent to the first line of a couplet port one of OLT.The transmission of corresponding hardware configuration data is from the port a of ONU1, to be sent to the PON interface 1 of OLT equipment, is finally sent to the port one of first line of a couplet port set 1.Wherein, the software resource numbering that ONU (1) is ONU, the hardware resource numbering that ONU1 is ONU.

Concrete, when ONU opens or changes business, residence network guard system is determined the operator under ONU, relevant configuration information is sent to ONU, and load the operator sign of corresponding operator for ONU, by setting up the mapping relations between operator's sign and ONU, and the mapping relations between operator's sign and first line of a couplet port set, ONU is according to the basic configuration information obtaining, operator's sign that utilization has been set up and the mapping relations between ONU, and the mapping relations between operator's sign and first line of a couplet port set, by identifying corresponding first line of a couplet port set with operator, to operator, initiate registration, operator can be to ONU issuing service configuration information, as speed limit, VLAN (Virtual Local Area Network, VLAN) divide, the precedence information of port etc., thereby set up communication port, carry out follow-up data exchange process.

The embodiment of the present invention provides a kind of method of shared EPON, by residence network guard system management PON system, determine the operator that ONU is corresponding, and operator's sign of adding the operator that ONU is corresponding in the communication protocol stack between OLT and ONU, set up operator's sign and the mapping relations of first line of a couplet port set and the mapping relations of operator's sign and ONU, and according to mapping relations, between operator and ONU, carry out data interaction.With need to compare in the prior art of carrying out jumping fiber between operator and common light distributing cabinet, in scheme provided by the invention, owing to having set up the mapping relations of operator's sign with first line of a couplet port set, and the mapping relations of operator's sign and ONU, so when user activates the service or changes operator, mapping relations according to operator's sign of having set up with first line of a couplet port set, and the mapping relations of operator's sign and ONU, just can realize the data interaction between ONU corresponding to Yu Gai operator of operator, without carry out complicated jumping fiber between operator and common light distributing cabinet, thereby reduced Information Security Risk, improved network reliability.When transmitting data, operator can only receive and own relevant ONU information, and do not receive the information of the ONU of other operators, ONU also can only receive the data that the operator corresponding with self transmits, and can't accept the data that other operators transmit, thereby improved the fail safe of shared PON system, also simplified the management of Liao Ge operator.Wherein, the large I of operator's management system decides according to the number of ONU corresponding to each operator, does not need to allocate in advance, thereby has strengthened the Joint construction and sharing of network, has reduced construction cost and operation cost.

Further, on the basis of the scheme shown in Fig. 3, the embodiment of the present invention also provides a kind of concrete scheme of method of shared EPON, the implementation further refinement of this programme to 102 in the scheme shown in Fig. 3, wherein, 102 can specific implementation be 1021-1022, as shown in Figure 4, comprising:

1021, described residence network guard system is that described ONU distributes ONU sign.

Wherein, ONU sign is used for distinguishing ONU.Wherein, the hardware resource of ONU numbering and software resource numbering all can be used as ONU sign, are used for distinguishing ONU.Wherein, the software resource of ONU numbering is by obtaining ONU is self-defined.

1022, described residence network guard system is set up the first mapping relations, and sets up the mapping relations of described operator sign and described ONU sign.

Wherein, the first mapping relations are the mapping relations of operator's sign and first line of a couplet port set.

Wherein, operator's sign is used for distinguishing operator.For all ONU load operator's sign, the operator's sign loading according to the ONU sign of distributing for ONU in 1021 with for ONU, the corresponding relation of known ONU sign and operator's sign, thus set up the mapping relations that operator's sign and ONU identify.

Optionally, on the basis of the scheme shown in Fig. 4, the embodiment of the present invention also provides a kind of concrete scheme of method of shared EPON, the implementation further refinement of this programme to 103 in the scheme shown in Fig. 4,103 can specific implementation be 1031a-1034a, or 103 can specific implementation be 1031b-1034b, as shown in Figure 5, comprising:
