Description
Technical field
The present invention relates to EPON (PON, PassiveOpticalNetwork) optical network unit (ONU in, OpticalNetworkUnit) registration technology, particularly relate to register method and the device of optical network unit in a kind of gigabit passive optical network (GPON, Gigabit-capablePassiveOpticalNetwork).
Background technology
Passive optical network technique is a kind of point-to-multipoint intelligent acess technology, it is by the optical line terminal (OLT of office side, OpticalLineTerminal), the ONU of user side and Optical Distribution Network (ODN, OpticalDistributionNetwork) composition.ODN is point-to-multipoint structure, and an OLT connects multiple ONU by ODN.
PON technology can be subdivided into again multiple: APON is using asynchronous transfer mode (ATM, AsynchronousTransferMode) as data link layer; EPON uses Ethernet as data link layer, and expands Ethernet and make it to have point-to-multipoint communication capacity; GPON adopts ATM/GPON encapsulation mode (GEM, GPONEncapsulatedMode) as link layer, can provide support to multiple business.
Along with user's improving constantly bandwidth sum quality of service requirement, soft exchange becomes extremely urgent, and increasing operator takes up to dispose Optical Access Network.But operator early stage Scaledeployment based on the access network of digital subscriber line (DSL, DigitalSubscriberLine), consider cost factor, existing network can not be replaced immediately, also can continue reservation.The optical network device that existing network uses substantially all follows the wide band model that TR_101 proposes.Consider from cost, evolution, network interworking and unified management maintenance etc. are many-sided, even operator wishes when multiple access network coexists, a unified wide band model also can be had to manage network, interconnect to improve, reduce equipment complexity, reduce costs.
Practice finds, the model that TR_101 proposes has well compatible and extensibility, is also applicable to other broadband access technology.Therefore, operator wishes that the deployment of GPON also can follow this model very much.
Broadband Forum proposes TR_156 in December, 2008 on TR_101 basis, it be to TR_101 supplement and expansion, specially for be GPON access technology.At present, TR_156 and G.984 become GPON equipment must abide by must two technical standards.
Fig. 1 is the ONU register flow path figure of G.984 middle formulation, and as shown in Figure 1, G.984 regulation ONU registration is carried out as follows:
Step 101:OLT regularly constantly issues serialnumberRequest message, finds ONU by the response obtaining this message.
Be in 01 state when ONU just powers on, after being connected with OLT, after receiving the downlink message of OLT, be switched to 02 state immediately.After this, receive first ploam message: upstream_overhead message, according to the running parameter (as transmitting optical power) of this message adjustment oneself, be switched to 03 state simultaneously.
Step 102:ONU receives the serialnumberRequest message from OLT, replys this message (serialnumberResponse message), reports the sequence number (SN, SerialNumber) of self.
The SN carried in the serialnumberResponse message that step 103:OLT replys according to ONU determines the current ONU whether having new access OLT, namely by determining whether that new SN (finding that new ONU reaches the standard grade) determines whether the ONU of new access, when defining the ONU of new access, OLT is that the ONU of this new access distributes ONUID, concrete, corresponding ONUID is found out by new sequence number, as the ONUID of this new access, and be handed down to ONU by Assign_ONU_ID message.ONU receives the Assign_ONU_ID message issuing oneself, and arrange the ONUID of oneself according to the ONUID carried in this Assign_ONU_ID message, this ONU is switched to 04 state.
Step 104:OLT issues rangingRequest message, to measure the balanced time delay of ONU.
Step 105:ONU sends rangingResponse message to OLT.
Step 106:OLT sends RequestPassword message to ONU, to obtain the Password of ONU, thus realizes the certification to ONU.
Step 107:ONU sends PasswordResponse message to OLT, carries the Password information of oneself.
Step 106 and step 107 are optional steps.
Balanced delay parameter is passed to ONU by ploam message by step 108:OLT, and ONU is according to the balanced time delay of the balanced delay parameter configuration oneself in this message, and the transmission starting point of adjustment uplink frame, identifying procedure terminates.
Fig. 2 is the ONU register flow path figure formulated in TR_156, and as shown in Figure 2, TR_156 specifies that OLT sets up by two kinds of modes and is connected with the management of ONU, and actual use can be generally the mixing of two kinds of modes.Wherein logon mode determines an ONUID into ONU configuration by the SN of ONU, and this is identical with the GPON register flow path of G.984 defined, repeats no more it here and realizes details.Another kind of mode is the determination realizing ONUID by introducing sign-on ID (RegistrationID), namely at the corresponding relation of OLT or webmaster side configuration RegistrationID and ONUID, whether legal the determining whether of RegistrationID that OLT reports according to ONU carries out subsequent authentication, follow-up register flow path with G.984 specify consistent.Below introduce the register flow path of ONU in detail, specifically comprise the following steps:
Step 201:OLT regularly constantly issues serialnumberRequest message, finds ONU by the response obtaining this message.
Be in 01 state when ONU just powers on, after being connected with OLT, after receiving the downlink message of OLT, be switched to 02 state immediately.After this, receive first ploam message: upstream_overhead message, according to the running parameter (as transmitting optical power) of this message adjustment oneself, be switched to 03 state simultaneously.
Step 202:ONU receives the serialnumberRequest message from OLT, replys this message (serialnumberResponse message), reports the sequence number (SN, SerialNumber) of self.The SN carried in the serialnumberResponse message that OLT replys according to ONU determines the current ONU whether having new access OLT, namely by determining whether that new SN (finding that new ONU reaches the standard grade) determines whether the ONU of new access, when defining the ONU of new access, determine the corresponding relation whether OLT being configured with this SN and ONUID, this ONU continues to carry out certification by SN backward, and authentication mode is with G.984 authentication mode is identical; Otherwise, carry out certification by RegistrationID mode, below illustrate it is how to realize by RegistrationID certification.
Step 203:OLT continues to issue RequestPassword message and obtains its RegistrationID to the ONU of this new access, and this message uses the frame format of Password_Request message.
Step 204:ONU receives Password_Request message, by the RegistrationID of RegistrationIDResponse message back oneself.
Step 203 and step 204 are the proprietary steps being realized registration by RegistrationID.
After step 205:OLT receives RegistrationIDResponse message, parse the RegistrationID in this message.And find out the corresponding relation whether OLT this locality is configured with RegistrationID and ONUID, if having, perform step 206, otherwise terminate current flow process.
Step 206:OLT by Assign_ONU_ID message to ONU issue into its configuration ONU_ID, for ONU distributes corresponding ONUID.ONU receives the Assign_ONU_ID message issuing oneself, the ONUID in this message is set to the ONUID of oneself, and is switched to 04 state.
Step 207:OLT issues rangingRequest message to ONU, to measure the balanced time delay of ONU.
Step 208:OLT sends RequestPassword message to ONU, to obtain the Password of ONU, thus realizes the certification to ONU.
Step 209:ONU sends PasswordResponse message to OLT, carries the Password information of oneself.
Step 208 and step 209 are optional steps.
Balanced delay parameter is passed to ONU by ploam message by step 210:OLT, and ONU is according to the balanced time delay of the balanced delay parameter configuration oneself in this message, and the transmission starting point of adjustment uplink frame, identifying procedure terminates.
From in above-mentioned flow process, G.984 regulation Password_Request message is issued by OLT in ranging process, asks password for OLT to ONU, to confirm the legitimacy of ONU.Before range finding, ONU is assigned with ONUID by OLT, and is switched to 04 state, and that is this message should issue when ONU is in 04 state.TR_156 then specifies: OLT is realized by the Password_Requestploam message of using G.984 prescribed by standard the acquisition of RegistrationID; ONU is reported by the RegistrationID filling ONU in the Password field of Password_Response message, detail no standard.Like this, when registering according to TR_156, OLT issue Password_Request message obtain RegistrationID time, ONU reality is only in 03 state, and this and G.984 regulation ONU receive this type of message in 04 state and produce contradiction.Meanwhile, because this message need fill ONUID, in order to show to obtain RegistrationID to appointment ONU.But be not also assigned with ONUID when ONU is in 03 state, the ONUID in above-mentioned Password_Request message will have no way of having filled out, and this has problems in realization.
The problems referred to above cause GPON product to support that GPON standard and TR_156 standard exist great difficulty at the same time.

Embodiment
Basic thought of the present invention is: by arranging sign-on ID request message and sign-on ID response message, smooth realization is able to the regulation obtaining ONU mark by RegistrationID at ONU register flow path, simultaneously, for ONU distributes interim ONU mark before sending sign-on ID request message, thus sign-on ID request message can be generated smoothly, thus realize the object of compatible register flow path G.984 and in TR_156.
For making the object, technical solutions and advantages of the present invention clearly understand, by the following examples also with reference to accompanying drawing, the present invention is described in more detail.
Fig. 3 is the flow chart of the register method of optical network unit in passive optical network of the present invention, as shown in Figure 3, for realizing register flow path of the present invention, need be configured by hybrid mode in OLT side, the authentication mode of SN and RegistrationID need be supported, i.e. the prior list item at a series of legal SN and the ONUID corresponding relation of OLT this locality configuration, RegistrationID and ONUID corresponding relation simultaneously.The register method of optical network unit in passive optical network of the present invention comprises the following steps:
Step 301:OLT regularly constantly issues serialnumberRequest message, finds ONU by the response obtaining this message.
Be in 01 state when ONU just powers on, after being connected with OLT, after receiving the downlink message of OLT, be switched to 02 state immediately.After this, receive first ploam message: upstream_overhead message, according to the running parameter (as transmitting optical power) of this message adjustment oneself, be switched to 03 state simultaneously.
Step 302:ONU receives the serialnumberRequest message from OLT, replys this message (serialnumberResponse message), reports the sequence number (SN, SerialNumber) of self.The SN carried in the serialnumberResponse message that OLT replys according to ONU determines the current ONU whether having new access OLT, namely by determining whether that new SN (finding that new ONU reaches the standard grade) determines whether the ONU of new access, when defining the ONU of new access, determine the corresponding relation whether OLT being configured with this SN and ONUID, this ONU continues to carry out certification by SN backward, and authentication mode is with G.984 authentication mode is identical; Otherwise, carry out certification by RegistrationID mode, below illustrate it is how to realize by RegistrationID certification.
Step 303:OLT is that the ONU of new access distributes interim ONUID, and generates the new SN of the ONU of this new access and the interim mapping table of interim ONUID.OLT generates RegistrationIDRequest message, and issues RegistrationIDRequest message to the ONU of this new access, to obtain its RegistrationID.Concrete, RegistrationIDRequest message format is as shown in table 1:
| byte number | content | describe |
| 1 | oNU_ID | the ONU corresponding to assigned I D sends message; OLT randomly draws a No. ID of not distributing in advance and is filled into this byte: this ID can not show with the SN+ONU_ID of the local configured in advance of OLT, Registration_ID+ONU_ID shows contained ID and repeats; OLT often issues this type of message of a frame, builds the interim list item (temp_ONU_ID+SN) of this ONU_ID and corresponding SN in its this locality; This ID also can not repeat with built interim list item ID. |
| 2 | 00001001 | show that type of message is " Registration_ID_Request " |
| 3--10 | oNU_SN | fill the SN of certain ONU; ONU resolves this position after receiving this message, if mate with the SN of self, then responds this frame, otherwise ignores this frame; (for obtaining the Registration ID that SN is the ONU of this value) |
| 11-12 | do not specify | reserved |
Table 1
As shown in Table 1, RegistrationIDRequest message comprises 12 bytes altogether, and wherein, interim ONU_ID takies a byte, and type of message takies a byte, and the SN information of ONU takies 8 bytes, and latter two byte is reserve bytes.It will be appreciated by those skilled in the art that taking of above-mentioned byte sequentially can be exchanged, as long as appoint in advance in agreement.
After step 304:ONU receives RegistrationIDRequest message, determine whether this message sends to oneself by ONUSN wherein.Namely the ONUSN by parsing determines whether to mate with the ONUSN of self, if coupling, this RegistrationIDRequest sends to this ONU.ONU replys the RegistrationID of oneself by RegistrationIDResponse message to OLT.Concrete, the form of RegistrationIDResponse message is as shown in table 2:
| Byte number | Content | Describe |
| 1 | ONU-ID | Fill Registration ID Request message and be with ONU_ID |
| 2 | 00000010 | Show that type of message is " Registration ID Response " |
| 3 | nnnnnnnn | Be effective number of bits from the 4th byte to the 11st byte |
| 4--11 | Registration ID | Fill a Registration ID/8 byte of ONU |
| 12 | Do not specify | Reserved |
Table 2
As shown in Table 2, RegistrationIDResponse message also comprises 12 bytes, first character joint is interim ONU_ID, this interim ONU_ID is and the identical ID comprised in RegistrationIDRequest message, second byte is type of message instruction byte, and the 3rd byte is effective byte instruction child node, to indicate from the 4th byte to the 11st byte as effective number of bits, 12nd byte is reserve bytes, expands use in the future to give over to.
Because multiple ONU can be connected under same OLT simultaneously, and the downstream message of OLT can issue with broadcast mode, thus each ONU all can receive RegistrationIDRequest message, for the ONU of different conditions, different to the processing mode of above-mentioned RegistrationIDRequest message.Below describe it in detail.For the ONU being in 02 state, ignore RegistrationIDRequest message.For being in 03 state, resolving the 3rd to the tenth byte of this message, parsing the SN in RegistrationIDRequest message, if mate with self SN, by the RegistrationIDResponse message format response shown in table 2, ONU maintains 03 state; If do not mate with self SN, ignore this message.For the ONU being in 04 or 05 state, because this message is consistent with Password_request form, resolve by Password_request, judge that whether the ONU_ID comprised in this RegistrationIDRequest message is consistent with the ONU_ID of this ONU self, if consistent, then determine that received message is Password_request message, respond this Password_request message, report self Password; If inconsistent, ignore this message.
After step 305:OLT receives RegistrationIDResponse message, parse the RegistrationID in this message.And find out the corresponding relation whether OLT this locality is configured with RegistrationID and ONUID, if having, perform step 306, otherwise terminate current flow process.
OLT is that the ONU_ID that this ONU distributes is different from temp_ONU_ID entrained in aforementioned RegistrationIDRequest message by Assign_ONU_ID message; Further, OLT is after obtaining and getting ONU_ID that ONU configures, and by interim for the SN of temp_ONU_ID and ONU set up before corresponding relation list deletion, namely this interim corresponding relation list item need be removed by machine before issuing Assign_ONU_ID.
Step 306:OLT by Assign_ONU_ID message to ONU issue into its configuration ONU_ID, for ONU distributes corresponding ONUID.ONU receives the Assign_ONU_ID message issuing oneself, the ONUID in this message is set to the ONUID of oneself, and is switched to 04 state.
Step 307:OLT issues rangingRequest message to ONU, to measure the balanced time delay of ONU.
Step 308:OLT sends RequestPassword message to ONU, to obtain the Password of ONU, thus realizes the certification to ONU.
Step 309:ONU sends PasswordResponse message to OLT, carries the Password information of oneself.
Step 308 and step 309 are optional steps.
Balanced delay parameter is passed to ONU by ploam message by step 310:OLT, and ONU is according to the balanced time delay of the balanced delay parameter configuration oneself in this message, and the transmission starting point of adjustment uplink frame, identifying procedure terminates.
