GPON is a kind of broadband passive light access technology that ITU-T (Bureau of Standards of international telecommunication union telecommunication) proposes, and transmission rate can provide voice, data and Video service simultaneously to enterprise and domestic consumer more than gigabit.The GPON system is generally by local side apparatus OLT (Optical Line Termination, optical line terminal), ustomer premises access equipment ONU (Optical Network Unit, optical network unit) and ODN (OpticalDistribution Network Optical Distribution Network) form.Adopt the network topology structure of point between OLT and the ONU, as shown in Figure 1 to multiple spot.

According to the GPON agreement, when ONU is linked in the GPON system, report its Equipment Serial Number (if OLT requires to report password then also should report password) to carry out device authentication to OLT, if authentication is passed through, then OLT can manage and provide service channel to it, otherwise OLT will refuse this ONU access network, thereby guarantee the network information security.Equipment Serial Number authenticates unsanctioned ONU and is called as illegal ONU.

The GPON agreement is that ONU has defined 7 state: O1 (initial condition), O2 (holding state), O3 (serial-number-state), O4 (distance measuring states), O5 (running status), O6 (POPUP state) and O7 (urgent halted state), and ONU can enter corresponding state after sending or receive the signal/protocol message of regulation.Agreement regulation is understood after ONU receives the ONU-ID that OLT issues enter the O4 state by O3, does not authenticate under the unsanctioned situation action of ONU and state transitions situation but be defined in Equipment Serial Number.

Summary of the invention

In view of above-mentioned, be badly in need of a kind of method at present, can under the situation that the ONU Equipment Serial Number does not have authentication to pass through, handle the method for illegal ONU.

The invention provides a kind of method, comprise by GPON system handles illegal optical network unit (ONU)

Step 1, optical network unit reports the Equipment Serial Number of optical network unit to optical line terminal,

Step 2, the Equipment Serial Number of optical network unit is received in the optical line terminal inspection, if this Equipment Serial Number is illegal, then optical line terminal writes down this Equipment Serial Number, and sends the message that enters urgent halted state to above-mentioned optical network unit.

As preferably, also comprise

Step 3, optical line terminal reconfigures parameter, and the Equipment Serial Number of former illegal optical network unit is recorded optical line terminal, and this Equipment Serial Number is legalized;

Step 4, optical line terminal send message makes optical network unit enter holding state.

As preferably, if store legal authentication list in the optical line terminal, it includes the Equipment Serial Number of the optical network unit that has authenticated.

As preferably, in the step 4, the message that optical line terminal sends is to activate the message of the former illegal optical network unit that is in urgent halted state.

As preferably, the testing fixture in the step 2 is optical line terminal or certificate server.

As preferably,, then also need report password with authentication if optical line terminal requires to report password.

As preferably, before step 1, at first to optical network unit transmit frame synchronizing signal and up expense Indication message, this optical network unit enters holding state to optical line terminal, and then optical line terminal is again to the request of optical network unit transmission to Equipment Serial Number.

The present invention has remedied the blank of GPON agreement, and the method for reasonably handling illegal ONU under the situation that the ONU Equipment Serial Number does not have authentication to pass through is provided, and the action of ONU and state status.

Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail.For the person of ordinary skill in the field, from detailed description of the invention, above-mentioned and other purposes of the present invention, feature and advantage will be apparent.

Description of drawings

Embodiment

Below in conjunction with the drawings and specific embodiments a kind of method by GPON system handles illegal optical network unit of the present invention is described in further detail.

As shown in Figure 2, a kind of deactivation process of the method by GPON system handles illegal optical network unit may further comprise the steps:

Step 1, OLT sends the effective DS frame that has as the synchronous downlink frame synchronizing signal PSYNC (Physical synchronization) of ONU and OLT to ONU, utilizes this signal to make OLT and ONU synchronous, and this moment, ONU was O1 state, i.e. initial condition.

Step 2, OLT sends the PLOAM message (upstream-overhead PLOAM) of carrying up expense parameter indication to ONU, and G.984.3 this PLOAM message defined by ITU-T, and this moment, ONU was O2 state, i.e. holding state.

Step 3, OLT requires receive sequence number to the ONU request message that transmits Sequence Number to ONU, and ONU reports this ONU Equipment Serial Number to OLT after receiving above-mentioned request message, and this moment, this ONU entered O3 state, i.e. serial-number-state.If OLT requires ONU to report password, then also need report password with authentication.

Step 4, the ONU Equipment Serial Number that the testing fixture inspection is received, judge whether this ONU Equipment Serial Number is legal, just whether in the legal authentication list of testing fixture, record is arranged, if in this legal authentication list, record is arranged, judge that then this ONU equipment is legal, if this sequence number is not configuration in OLT, just do not write down the value of this ONU Equipment Serial Number among the OLT, it does not have record in the legal authentication list of testing fixture, judge that then this ONU Equipment Serial Number is illegal, this ONU equipment is illegal, forwards step 5 to.Described testing fixture can be OLT itself, also can be to be connected to the independently device of certificate server class with OLT, wherein disposes legal authentication list, records the sequence number of legal ONU equipment.

Step 5, testing fixture write down the Equipment Serial Number of this ONU, and OLT sends back to the ONU that reports this Equipment Serial Number with deexcitation message (Disableserial number (disable)), notifies this ONU to enter the O7 state, promptly urgent halted state.

As shown in Figure 3, a kind of activation of the method by GPON system handles illegal optical network unit comprises:

After above-mentioned steps 5 finished, testing fixture reconfigured ONU Equipment Serial Number authentication list, and this ONU Equipment Serial Number is added in the legal authentication list, and former illegal ONU is legalized; Then OLT sends and activates ONU message (Disable serial number (enable)), activates the former illegal ONU that is in urgent halted state, notifies this ONU to enter O2 state, i.e. holding state.
