Abstract
The invention provides a method for processing an illegal optical network unit (ONU) by a GPON system, comprising the following steps: firstly, the ONU reports an equipment serial number of the ONU toan OLT; secondly, a detecting device detects the received equipment serial number, if the equipment serial number is illegal, the detecting device records the equipment serial number, and the OLT sends a message of entering into an emergency stopping state to the ONU. The invention makes up the blank of a GPON protocol, provides a method for reasonably processing the illegal ONU under the condition that the equipment serial number of the ONU does not pass the authentification and provides the condition of the action and the state of the ONU.
Description
Technical field
The present invention relates to the processing method of a kind of optical network unit (ONU), particularly a kind of method by GPON system handles illegal optical network unit.
Background technology
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 to enterprise and domestic consumer simultaneously 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 to multiple spot, as shown in Figure 1.
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.The unsanctioned ONU of Equipment Serial Number authentication 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 get into corresponding state after sending or receive the signal/protocol message of regulation.Agreement regulation can be by O3 entering O4 state after ONU receives the ONU-ID that OLT issues, but is not defined under the unsanctioned situation of Equipment Serial Number authentication the action of ONU and state transitions situation.
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 present invention provides a kind of method by GPON system handles illegal optical network unit (ONU), comprises
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 gets into 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 are sent message makes optical network unit get into 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 of authentication.
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, optical line terminal is at first to optical network unit transmit frame synchronizing signal and up expense Indication message, and this optical network unit gets into holding state, and then optical line terminal sends the request to Equipment Serial Number to optical network unit again.
The present invention has remedied the blank of GPON agreement, and the method for under the situation that the ONU Equipment Serial Number does not have authentication to pass through, reasonably handling illegal ONU is provided, and the action of ONU and state status.
Below in conjunction with accompanying drawing, specific embodiments of the invention is done further to specify.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 obvious.
Description of drawings
Fig. 1 is the simplified structure diagram of GPON of the prior art system.
Fig. 2 is the deexcitation flow chart of the present invention's one preferred embodiment.
Fig. 3 is the figure of activation process again of the present invention's one preferred embodiment.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment a kind of method by GPON system handles illegal optical network unit of the present invention is done further to specify.
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 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 got into 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 judges whether this ONU Equipment Serial Number is legal; Just whether in the legal authentication list of testing fixture, record is arranged,, judge that then this ONU equipment is legal if in this legal authentication list, record is arranged; 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, judges 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, the Equipment Serial Number of this ONU of testing fixture record, OLT sends back to the ONU that reports this Equipment Serial Number with deexcitation message (Disableserial number (disable)), notifies this ONU to get into 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 get into O2 state, i.e. holding state.
The above is merely preferred embodiment of the present invention, is not to be used for limiting practical range of the present invention; If do not break away from the spirit and scope of the present invention, the present invention is made amendment or is equal to replacement, all should be encompassed in the middle of the protection range of claim of the present invention.
