Description

Optical fiber position determining method and device, network element, storage medium and processor

Technical Field

The present invention relates to the field of communications, and in particular, to a method and an apparatus for determining an optical fiber position, a network element, a storage medium, and a processor.

Background

In an xPON Network of a Passive Optical Network (PON), fig. 1 is a schematic diagram of a networking System in the related art, and as shown in fig. 1, the System is composed of an Element Management System (EMS), an Optical Line Terminal (OLT), an Optical Distribution Network (ODN), and a plurality of Optical Network Units (ONU): the OLT is used as central office equipment to manage, connect and assemble a plurality of ONU equipment by taking a PON port as a unit through an ODN network; the ONU equipment receives the management of the OLT equipment to realize the access of user services, thereby realizing the functions of data services, configuration management and the like; the ODN network is mainly composed of a trunk fiber, a plurality of branch fibers, and an optical splitter or other connectors for connecting the trunk fiber and the branch fibers. The xPON serves as a topological structure of point-to-multipoint: managing and maintaining a plurality of ONUs by taking PON ports corresponding to xPON OLTs as basic units: the xPON OLT firstly realizes the registration authentication of the ONU by taking the PON port as a unit, establishes a logic forwarding channel through logic configuration after the ONU finishes the registration authentication and realizes the uplink and downlink forwarding of the service/management data of a plurality of ONUs under the PON port in the following modes: the transmission direction from the OLT to the ONU is a downlink direction (downlink), the downlink direction adopts a Broadcast mode (Broadcast) to send data, and the ONU judges whether the data is valid according to a logic identifier distributed by the OLT and determines to receive or discard the data; the transmission direction from the ONU to the OLT is an uplink direction (upstream), the uplink direction employs a Time Division Multiple Access (TDMA), and the ONU must transmit an uplink Burst (Burst) signal according to an uplink Bandwidth timeslot (Bwmap, Bandwidth Map) allocated by the OLT.

Therefore, in the management and maintenance of the ONU by the xPON OLT, the basic functions are to realize the registration and authentication of the ONU: the registering means that a discovery window is periodically issued by the OLT under the condition that the optical path quality is normal, the ONU sends registration information under the control of the OLT and completes an automatic discovery process, as long as the optical path quality (such as distance, optical power and the like) meets requirements, the ONU can respond and interact according to a corresponding xPON standard, the interactive registration process can be completed according to protocols specified by different PON mechanisms, and the ONU becomes an unauthenticated ONU at this time.

The unauthenticated ONU under the PON port is in a state that data can not be forwarded, and service data can be normally forwarded only after authentication. The authentication is that the OLT compares basic registration authentication identification information (pre-configured or newly-established) of the ONU which is stored by taking the PON port as a unit with the basic registration authentication identification information which is reported by the ONU in an unauthenticated state. And when the corresponding ONU basic identification information at the PON port is empty or does not accord with the basic identification information reported by the ONU, the OLT keeps the ONU in an unauthenticated state.

The basic registration authentication identification information of the authentication interaction between the OLT and the ONU uniquely identifies the specific ONU, including but not limited to mac address, local (logical ONU identification)/local + pw (logical ONU identification + password) adopted in the EPON/10GEPON system, SN number (serial number), local (logical ONU identification)/local + pw (logical ONU identification + password) adopted in the GPON/XGPON system, and other information playing a role similar to ONU identification. In the authentication process between the OLT and the ONU, one or more basic identification information can be flexibly adopted for authentication according to an authentication mode configured based on the PON port as a unit.

By adopting the registration authentication mode, the judgment of the validity of the accessed ONU by the OLT is ensured. However, the premise is that the ONU basic identification information configured by the OLT based on the PON port and the basic identification information reported by the actual ONU can correspond to each other one by one, and the basic identification information allocated to each ONU is unique to prevent the ONU registration authentication information from conflicting.

The physical basis for ensuring the successful registration authentication process based on basic registration authentication identification information interaction between the OLT equipment and the ONU equipment of the xPON system is that the physical optical path connection between the OLT equipment and the ONU equipment in the xPON system is correct. Two major features of the xPON system present challenges to this:

first, due to the PToMP topology adopted by xPON and similar systems, for a specific PON port, there is a main fiber that needs to be in one-to-one correspondence, and a plurality of branch fibers that correspond to the main fiber through optical connectors such as optical splitters; for a PToP system, the optical fibers may correspond to the ports of the local side devices one to one; however, as local side devices (such as xPON OLT devices) have multiple ports, the corresponding optical fibers (including trunk optical fibers, branch optical fibers, etc.) of the PToMP/PToP devices are massive; further, for a network, the number of optical fibers managed by a plurality of PToMP/PToP local side devices (such as xPON OLT devices) is further increased. A large number of optical fibers (a main optical path and branch optical fibers) complete the connection between the olton port and the ONU in the engineering construction and operation and maintenance processes, and a great challenge is posed to the management of optical fiber resources of the ODN network.

And a second point: another feature of the xPON system is that the ODN network (including optical fibers and connecting devices) connecting the OLT and the ONUs does not contain electronic components and electronic power supplies. The above characteristics also result in the inability to identify and manage ODN network fiber resources in a traditional software manner based on the cost advantage. Namely, the system is faced with the huge contradiction of the massive optical fiber resources and the incapability of direct management.

Therefore, the above problems are essentially in the application scenarios of the xPON network, especially the massive optical fibers (including trunk optical fibers and branch optical fibers) caused by the P2MP topology, and the cost problems that the optical fiber resources determined by the passive characteristics of the xPON ODN cannot be located, queried and managed by the built-in software, and other management technologies may be adopted. The above problem makes it increasingly difficult to manage optical fibers in FTTx scenarios because the splitting ratio becomes larger at PON ports, which results in more branch optical fibers. Under the background of massive optical fibers, in more and more service application scenes of new construction, cutting and replacement, once optical fibers are inserted wrongly (including that a main optical fiber is inserted wrongly into an OLT PON port and a branch optical fiber is connected wrongly into the main optical fiber), the efficiency of searching corresponding wrong optical fibers and correct ports is extremely low, and the ONU registration authentication of the xPON OLT cannot meet the requirements based on service recovery due to the fact that the ONU registration authentication is easily interfered. The physical medium labels (such as paper labels) attached to the optical fibers, which are traditionally adopted, not only bring cost rise, but also have the disadvantages of low efficiency, low accuracy and easy external interference. The above problems also exist in other communication systems that employ similar networking topologies and network element sub-node management approaches.

In view of the above technical problems in the related art, no effective solution has been proposed at present.

For a better understanding of the embodiments of the present invention, the present invention is further explained below with reference to preferred embodiments.

The preferred embodiment of the invention provides a method for realizing optical fiber management and rapid positioning recovery of an xPON system ODN (optical line terminal) in order to solve the problem that optical fiber positioning management is difficult, especially positioning recovery is difficult under the condition of wrong insertion, in the scene of mass optical fiber connection between an OLT (optical line terminal) and an ONU (optical network unit) of the conventional xPON ODN. The management, positioning and fast recovery method is consistent for a system which performs registration authentication between local side equipment (such as OLT) and user terminal equipment (such as ONU/ONT) through basic registration authentication identification information (including but not limited to mac address/LOID/LOID + PW of EPON/10GEPON system, SN/LOID/LOID + PW of GPON/XG EPON system and other similar basic registration authentication identification information) to realize terminal access validity control and service forwarding or other point-to-multipoint (P2MP) working mechanisms adopting similar management authentication methods.

In an xPON and related networks, the preferred embodiment of the present invention provides that, in a PON port as a unit, an OLT device generates and maintains an ONU configuration identification information table under the PON port, compares, according to actual state information of the ONU under the PON port (registration authentication information reported by the ONU), ONU configuration information stored by the OLT and ONU configuration information actually reported by the PON port, determines, by a certain policy, a comparison result with the PON port as a unit, analyzes whether a fault exists and a fault range is a trunk fiber or a branch fiber, and gives an actual correct port position. Meanwhile, according to a certain strategy, the access of ONU registration identification information under the condition of optical fiber misplugging can be realized, so that the method for rapidly positioning and recovering the optical fiber misplugging of the ODN network in the xPON system is realized.

The preferred embodiment of the invention provides a method for fast positioning and recovering an ODN network optical fiber insertion error in an xPON system, which comprises the following steps:

the first step is as follows: reading ONU configuration information by taking a PON port as a unit, storing and maintaining a relation table 1(ONU configuration information-actual state-PON port relation corresponding table) of the configuration information of all ONUs and corresponding PON ports; automatically or artificially triggering to actively check the state of the PON port according to a certain strategy (including the optical path alarm change of the PON port and the optical link performance statistic change of the PON port), and reading the actual state of the ONU: the method comprises the steps of including the actual state of a configured ONU and the actual state of an unauthenticated ONU; acquiring and maintaining a relation table 2(ONU configuration information-actual state PON port-network element relation corresponding table) of all configuration information of the managed network elements and corresponding PON ports through a network management or operation and maintenance platform;

the second step is that: in the query of the actual state of the PON port, when an unauthenticated ONU exists under the PON port and configured ONUs under the PON port are not online or unauthenticated ONUs exist under the PON port and the number of unauthenticated ONUs under the PON port is greater than a specified threshold value, the PON port is marked as a specific alarm PON port (equivalent to the specified PON port). Initiating a registration process for all the unauthenticated ONUs in a unit of a specific alarm PON port according to a certain strategy, and acquiring or updating registration identification information (including but not limited to MAC addresses, LOID/LOID + PW in an E/10GEPON ONU system, SN, LOID/LOID + PW in a GPON ONU system, and other software information (including but not limited to the geographic position information of the ONUs) capable of marking the ONU information) of the unauthenticated ONUs.

The third step: a network element acquires and alarms a PON port (equivalent to the designated PON port), and the unauthenticated ONU registration identification information is compared with a relation table 1(ONU configuration information-actual state-PON port relation corresponding table), the unauthenticated ONU registration identification information of the designated PON port is searched by taking the PON port as a unit, a matching threshold value 1 (equivalent to the first preset threshold value) is set at the same time, and the matching threshold value 1 is assigned according to a certain rule (the rule includes but is not limited to: dynamically acquiring the total number of all the unauthenticated ONUs under the PON port by taking the PON port as a unit, and rounding after calculation according to a certain ratio), and can be manually modified; the third step specifically comprises:

3.1) when the registration identification information of the unauthenticated ONU at the specified PON port is matched with the registration identification information of the ONU configuration information at the specific PON port (equivalent to the first PON port) in the relation table 1, and the number of the matched ONUs exceeds a threshold value 1, the trunk optical fiber is considered to be inserted wrongly. Generating an actual PON port to be inserted position (including a PON port) specifying an unauthenticated ONU according to the ONU configuration information stored in the relationship table 1, where the actual PON port to be inserted is the specific PON port in the relationship table 1; and marking the specific alarm PON port as the misplug PON port. The network element generates an alarm notification 1 (corresponding to the first alarm message) including, but not limited to, an alarm name (e.g., trunk fiber misplugging), misplugging of a PON port, and plugging of a PON port. Meanwhile, the network element software guides the field to replace the optical fiber by specially lighting (lighting in different and service states) the PON port of the designated PON port (mistakenly plugging the PON port and plugging the PON port).

3.2) when the registration identification information of the unauthenticated ONU at the specified PON port is matched with the registration identification information of the ONU configuration information at the specific PON port (equivalent to the first PON port) in the relation table 1, but the number of the matched ONUs is lower than the threshold value 1, the branch optical fiber is considered to be inserted wrongly. According to the ONU configuration information stored in the relation table 1, an access position of an unauthenticated ONU at a specified PON port is generated, and the network element generates and reports an alarm notification 2 (corresponding to the second alarm message) (including but not limited to an alarm name (e.g., a branch optical fiber is erroneously inserted) and information of an erroneously inserted ONU (including but not limited to an erroneously inserted PON port and an intentionally inserted PON port)).

3.3) when the non-authenticated ONU registration identification information of the specified PON port is not matched with the registration identification information of the ONU configuration information under the specific PON port in the relation table 1, generating a corresponding network element error relation table 3 (including but not limited to ONU registration identification information, PON port and network element information) according to the corresponding relation between the non-matched ONU registration information and the PON port where the non-matched ONU registration information is located. The network element maintains or updates the table automatically or manually according to the policy defined in (1). The network element generates and reports an alarm notification 3 (corresponding to the third alarm message) (e.g., the PON port ONU registration information does not match).

The fourth step: after receiving the network element specific alarm notification message 3, the network manager obtains a relationship table 3 stored and maintained by the network element (including without limitation that no ONU registration identification information is registered at a PON port corresponding to the network element), and compares all network element configuration information stored and maintained by the network manager with a relationship table 2 corresponding to the PON port (ONU configuration information-actual state-PON port-network element relationship correspondence table). Searching the registered identification information of the unauthorized ONU of the appointed PON port by taking the PON port as a unit, and simultaneously setting a matching threshold value 2 (which is equivalent to the second preset threshold value), wherein the matching threshold value 2 can be assigned according to a certain rule (the rule comprises but is not limited to dynamically acquiring the total number of all the unauthorized ONUs under the PON port by taking the PON port as a unit, and calculating according to a certain ratio and then rounding, the matching threshold value 1 is the same as the matching threshold value 2 in a default mode), and can be modified manually, and the fourth step specifically comprises the following steps:

4.1) when the registration identification information of the unauthenticated ONU at the specified PON port is matched with the registration identification information of the ONU configuration information at the specific PON port (corresponding to the second PON port) in the relation table 2, and the number of the matched ONUs exceeds a threshold value 2, the main optical fiber is considered to be inserted wrongly. Generating the actual port-to-be-plugged position (network element + PON port) of the specified unauthenticated ONU (including the network element and the PON port) according to the ONU configuration information stored in the relation table 2, wherein the actual port-to-be-plugged is a specific port (network element + PON port) in the relation table 2; and marking the specific alarm PON port as the misplug PON port. And generates an alarm 1 (corresponding to the fourth predetermined threshold) including, but not limited to, alarm names (e.g., trunk fiber misplugging), misplugging ports (net element + PON port), and due-to-plug ports (net element + PON port). Meanwhile, the network management informs the network element software to guide the field replacement of the optical fiber by special lighting (lighting in different and service states) of the PON port of the specified port (the misplugging port and the to-be-plugged port).

4.2) when the registration identification information of the unauthenticated ONU at the specified PON port is matched with the registration identification information of the ONU configuration information under the specific PON port in the relationship table 2, but the number of the matched ONUs is lower than the threshold 2, it is determined that the branch optical fiber is erroneously inserted, and the access position of the unauthenticated ONU at the specified port (network element + PON port) is generated according to the ONU configuration information stored in the relationship table 2, and the network element generates and reports an alarm 2 (equivalent to the fifth predetermined threshold) (including but not limited to: alarm name (e.g., supporting optical fiber misplugging), misplugging ONU information (including, but not limited to, misplugging network element interface, and network element port to be plugged).

4.3) when the un-authenticated ONU registration identification information of the specified PON port is not matched with the registration identification information of the ONU configuration information under the specific PON port in the relation table completely, generating a network management error relation table 3 (including but not limited to ONU registration identification information, PON port and network element information) according to the corresponding relation between the un-matched ONU registration information and the PON port under all network elements governed by the network management. The network management error relation table 3 is a complete set of the network element error relation table 3; the network element error relation table 3 is a subset of the network management error relation table 3. The network element maintains or updates the table automatically or manually according to the policy defined in (1). An alarm notification 3 is generated (e.g., the PON port ONU registration information does not match).

The fifth step: according to a certain policy, a service restoration rule is manually formulated for the OLT configuration data in the corresponding logical range (the alarm 1 is a PON port, and the alarm 2/3 is an ONU) of the reported alarm notification 1/2/3, and the fifth step specifically includes:

5.1) configuration data priority: when the reported data under the PON port is inconsistent with the OLT configuration data, taking the OLT configuration data as a standard, simultaneously generating an alarm notification according to the comparison result in the steps (3) and (4), optionally generating a work order on a third-party operation and maintenance platform, and guiding subsequent manual change of trunk or branch optical fibers by a certain method (for example, network element software guides field replacement of optical fibers by special lighting (different and service state lighting) of the PON port of a specified PON port (wrongly plugged into the PON port or a PON port to be plugged into the PON port) until ONU registration identification data reported by the PON port actually is consistent with OLT configuration ONU registration information;

5.2) reporting information preferentially: when the data reported by the PON port is inconsistent with the OLT configuration data, the ONU registration identification actually reported by the PON port is taken as the standard. The OLT applies for temporary resources according to a certain method, and stores the original configuration ONU registration data and the related ONU service data of the corresponding PON port. Clearing the ONU registration information and the relevant service data configured under the current PON port, and migrating the relevant data (including the registration data, the service data and the like) in the corresponding (to-be-plugged) ports in the relation tables 2 and 3 to the current PON port in a certain method according to the ONU registration information actually reported under the PON port. And storing ONU registration information configured by the PON port in the temporary resource and processing according to whether the registration information accords with the actual PON port report information under the OLT or the network management. And if the information is consistent, transferring the configuration information stored in the temporary resource to the corresponding PON port. If no corresponding data exists and the same network element has the idle PON port resource, the same network element is migrated to the idle port under the same network element; if no conforming data exists and no idle PON port resource exists in the same network element, the use of the reported information priority rule is forbidden;

and 5.3) the priority of the configuration data can be artificially modified and the application range of the reported information at different PON ports is preferred.

And a sixth step: when the optical path state of the designated PON port (original PON port/misplugging PON port) or the registration state of the unauthenticated ONU changes, and when the unauthenticated ONU in the misplugging port is in a non-unauthenticated state under the PON port to be plugged, the alarm 1/2 (trunk/branch optical fiber misplugging) is recovered, and the misplugging PON port mark is cleared. And meanwhile, updating and maintaining an OLT relation table.

In addition to the above solutions, the preferred embodiment of the present invention may also apply other software information that can uniquely identify the ONU as a judgment basis. Such as the geographical location identifier reported by the ONU. The OLT PON port configures the ONU information list and includes the geographical location information of the configured ONU, that is, the OLT PON port includes the geographical information of the configured ONU. And the network manager maintains the geographic information of all PON ports.

In the above second step, in addition to the basic processing step: when the PON port finds the unauthenticated ONU, the geographical position information of the ONU is simultaneously acquired through software setting besides the registration authentication information of the ONU (including but not limited to directly extracting the geographical position information of the ONU at the registration incomplete stage, or after the ONU finishes registration and acquires necessary software information such as the geographical position information of the relevant ONU, the relevant ONU is unregistered and is in an unregistered state). And measuring the distances of all the unauthenticated ONUs under the PON port, and confirming the possible geographical coverage range by taking the longest distance as the radius and the central point of the geographical position information of all the ONUs as the center of a circle.

In the third step, except the basic processing step, all PON ports under the network element or the network management are compared according to the possible geographic coverage, all PON ports in the possible geographic coverage are obtained, the ONU information configured under these PON ports is compared with the unregistered ONU information (the information includes, but is not limited to, MAC address, LOID/LOID + PW in E/10GEPON ONU system, SN, LOID/LOID + PW in GPON ONU system, and other software information (including, but is not limited to, the geographic location information of ONU, etc.) that can mark the ONU information), and the matching condition is determined. And then processing according to the fourth step to the sixth step.

By adopting the method provided by the preferred embodiment of the invention, the registration identification information table of the ONU under the OLT is generated and maintained through a certain rule, the comparison between the actual information of the ONU under the PON port and the configuration information on the OLT is realized by taking the PON as a unit, and the interpretation of the connection relationship between the OLT and the ONU is realized according to a certain strategy. Therefore, in the xPON application, the legality of the ODN optical fiber between the OLT and the ONU is judged, positioned and recovered through the interaction of basic registration authentication identification information of the OLT and the ONU, the defects that in the conventional mode, massive optical fiber positioning management and fault recovery are difficult, low in efficiency and easy to interfere between a local side and terminal equipment in an xPON network and a system adopting a similar mechanism are overcome, the ODN optical fiber management and fault positioning recovery efficiency in the xPON network is improved, and meanwhile, a standard communication protocol based on the xPON system is adopted as an ODN optical fiber management positioning identification, so that an efficient and convenient method is provided for opening, management and maintenance, and the method has good expansibility.

Fig. 3 is a flowchart of xPON registration authentication according to a preferred embodiment of the present invention, which takes registration authentication in the MAC address mode of an EPON system as an example, and other systems are similar.

The EPON system defines an MAC control mechanism of the point-to-multipoint optical network by adopting a multipoint control protocol (MPCP), and completes automatic discovery and registration of the ONU, clock synchronization of the ONU and dynamic ranging in an automatic discovery mode through the operation of the MPCP; and monitoring the registration state of the ONU and dynamic bandwidth allocation of the ONU are completed in a common working mode.

The MPCP protocol defines 5 protocol frames for the management operation of the PON network: 1) grant frame (GATE): sending an authorized time slice to the ONU in an initialization and common working mode, and transmitting data by the ONU according to the allocated time slice; 2) REPORT frame (REPORT): the ONU reports the state of the ONU and the request to the OLT; 3) registration request frame (REGISTER _ REQ): the ONU sends a registration request to the OLT; 4) registration frame (REGISTER): REGISTER _ REQ message for OLT to respond to ONU; 5) registration response frame (REGISTER _ ACK): the ONU sends an indication to the OLT to end the entire registration process. The authorization frame and the three registration frames are used in the auto-discovery mode, while in the normal mode, only the interaction between the authorization frame and the report frame is included.

MPCP by default does not allow ONU transmission, i.e. the ONU cannot forward any data (nor turn on the laser) before getting the OLT's authorization. MPCP detects a newly connected ONU through auto-discovery mode.

Step 1: the OLT starts an auto-discovery mode and allocates a discovery window, sends a discovery Grant (GATE) message in a broadcast manner, and announces the start time and length of a discovery slot.

Step 2: and the uninitialized ONU responds to the discovery GATE message to complete the clock synchronization of the OLT and the ONU. After the ONU local clock reaches the discovery time slot, the ONU sends a REGISTER _ REQ message after random delay, and the message comprises the source MAC address of the ONU and the ONU local clock label representing the sending time. The OLT supports the capability of authenticating the validity of the ONU based on the MAC address of the ONU, and the access of the illegal ONU should be refused.

And step 3: after the OLT analyzes and confirms the REGISTER _ REQ message, the OLT transmits the REGISTER message to the ONU which is being initialized by using the MAC address of the ONU. The message contains a Logical Link Identification (LLID) assigned by the OLT to uniquely identify the ONU.

And 4, step 4: the OLT allocates upstream bandwidth to the ONU by means of a Logical Link Identification (LLID) that uniquely identifies the ONU.

And 5: after receiving the REGISTER and normal GATE messages, the ONU sends a REGISTER _ ACK message in the assigned grant slot to inform the OLT that it has successfully parsed the REGISTER message. The whole automatic discovery process is completed.

Through the five steps, and after the standard OAM and the extended OAM are found and negotiated successfully, the ONU adopting the MAC address as a registration authentication object mode can enter a normal working state. If the LOID authentication mode specified by the EPON system is adopted, the following authentication steps need to be further completed:

step 6: the OLT initiates authentication of the ONU by sending an Auth _ Request message to the ONU.

And 7: the ONU receives the message and sends an Auth _ Response message to the OLT, which contains its logical identification (LOID and Password).

And 8: and the OLT verifies the legality and correctness of the logic identification of the ONU. If the verification passes, an Auth _ Suprocess message is sent to the ONU and the authentication state of the ONU is switched to an "authorized" state.

And step 9: and if the ONU fails in authentication, the OLT sends an Auth _ Failure message to the ONU and keeps the ONU in an unauthorized state.

Referring to fig. 1, a schematic diagram of the system provided by the preferred embodiment of the present invention also includes an EMS100, an OLT200, an ODN300, and an ONU400, wherein,

EMS100, which is used to configure, manage and maintain OLT200 and the EPON network; the EMS network manager maintains and manages the history information of the OLT200 and the ONU400 and related alarm and notification messages. And the specific abnormal information can be judged and positioned according to the related alarm and notification message.

The OLT200 is configured to periodically start a discovery process of the ONU, allocate a link identifier (e.g., LLID (EPON system)/ONU ID (GPON system)) to the ONU400, and receive and determine whether basic registration authentication information reported by the ONU in the discovery process is consistent with OLT local configuration storage information. If the reported information is consistent with the configuration storage information, the registration and authentication of the ONU400 on the OLT200 are completed, a corresponding uplink time slot is allocated to the ONU400, and the ONU400 uploads data in the time slot allocated to the OLT200 by configuration; otherwise, the ONU400 registers the authentication failure on the OLT200 and is not allowed to forward any general service data except for the protocol interaction.

The ODN300 is configured to connect the ONUs 400 with different numbers under the OLT200, serve as a direct physical connection channel between the OLT200 and the ONUs 400, and are formed by combining multiple optical fibers (one or two (mutually protected) trunk optical fibers and multiple branch optical fibers) and other related physical optical devices in units of PON ports;

the ONU400 is configured to assume a role of a terminal device of a home user, receive management of the OLT200, report registration authentication identification information of the ONU itself in a process of retrying an online process caused by a new power-on of the ONU or a power-off reason, and respond to an instruction of the OLT. And receiving ONU identification (such as LLID (EPON system)/ONU ID (GPON system) and the like) allocated by the OLT under the control of the OLT, finishing registration authentication reception and forwarding data according to a time slot allocated by the OLT. When the basic registration authentication information reported by the ONU is inconsistent with the locally stored data of the OLT, the ONU receives the control of the OLT, responds again in the registration period allowed by the OLT and reports the registration authentication identification information of the ONU.

And the network manager maintains the geographic information of all PON ports.

In the above S402, in addition to the basic processing step: when the PON port finds the unauthenticated ONU, the geographical position information of the ONU is simultaneously acquired through software setting besides the registration authentication information of the ONU (including but not limited to directly extracting the geographical position information of the ONU at the registration incomplete stage, or after the ONU finishes registration and acquires necessary software information such as the geographical position information of the relevant ONU, the relevant ONU is unregistered and is in an unregistered state). And measuring the distances of all the unauthenticated ONUs under the PON port, and confirming the possible geographical coverage range by taking the longest distance as the radius and the central point of the geographical position information of all the ONUs as the center of a circle.

In S403, except for the basic processing step, comparing the geographical information of all PON ports in the network element or the network management according to the possible geographical coverage, obtaining all PON ports in the possible geographical coverage, comparing the configured ONU information under these PON ports with the unregistered ONU information (information includes, but is not limited to, MAC address, LOID/LOID + PW in E/10GEPON ONU system, SN, LOID/LOID + PW in GPON ONU system, and other software information (including, but is not limited to, geographical location information of ONU), which can mark the ONU information), and determining the matching condition. Thereafter, processing proceeds according to S404 to S406.
