Technical field

This application relates to, but is not limited to, the field of passive optical network technology.

Background technique

Passive Optical Network (PON) is a fiber transmission and access technology. An optical network unit (ONU) is divided into an active optical network unit and a passive optical network unit. The ONU is a client device that can provide data, voice, and the like to users. Generally, the PON is connected to an optical line terminal (Optical Line Terminal, OLT for short) using a single fiber, and then the OLT is connected to the ONU.

In the related art, the ONU service is enabled in the PON system of some large telecom operators: the service automatic activation system is deployed in the PON system, and the service is automatically activated when the operator's business hall accepts the request for the customer to open the service (for example, broadband Internet access). The system generates a corresponding work order according to the customer's opening service request, and then the service automatic activation system sends the work order to the element management system (EMS), so that the EMS system delivers the corresponding ONU according to the work order. The configuration data indicates that the ONU service is enabled when the ONU completes the configuration.

However, for non-large-scale telecom operators, the service auto-activation system is often not deployed due to cost, etc., so the ONU service can be activated only by manually configuring the ONU by the staff, making the ONU service less efficient and manual.

Embodiments of the invention

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that, in the case of no conflict, the features in the embodiments and the embodiments herein may be arbitrarily combined with each other.

The steps illustrated in the flowchart of the figures may be executed in a computer system in accordance with a set of computer executable instructions. Also, although logical sequences are shown in the flowcharts, in some cases the steps shown or described may be performed in a different order than the ones described herein.

The embodiment of the invention provides a method for opening an optical network unit service. FIG. 1 is a schematic flowchart diagram of a method for opening an optical network unit service according to an embodiment of the present invention. The optical network unit service provisioning method provided by this embodiment may include the following steps, that is, step 110 to step 130:

Step 110: Listening to a Trap message reported by the optical line terminal to the network element management system in the passive optical network system;

Step 120: Determine whether the monitored Trap message is a preset reminder message, where the preset reminder message is that the optical line terminal detects the Trap message that is reported after the unconfigured optical network unit accesses the optical line terminal.

Step 130: When the Trap message is a preset reminder message, configure the optical network unit according to the preset reminder message, the preset configuration information database, and the northbound interface protocol provided by the network element management system.

The optical network unit service provisioning method provided by the embodiment of the invention is used for opening an optical network unit (ONU) service in a passive optical network system. When the configuration of the ONU is completed, the ONU service is activated. The passive optical network system may include an element management system (EMS), an ONU, and an optical line terminal (OLT). The EMS is used as a network element management system to obtain an OLT message, and sends data to the OLT, where the OLT is used to connect the optical fiber. The ONU of the trunk device of the trunk line, an OLT can be connected to multiple ONUs, and the ONU is a terminal device installed by the client.

Optionally, in the embodiment of the present invention, the trap message reported by the OLT to the EMS in the ISP is the Trap message reported by the OLT to the EMS. The preset reminder message is a trap message that the OLT detects the unconfigured ONU and reports it to the EMS when the unconfigured ONU accesses the OLT. Generally, after the unconfigured ONU is installed and powered on, the OLT detects the ONU device and reports a trap message to the EMS that the content of the ONU is not configured. Therefore, it is determined that the Trap message sent by the OLT to the EMS is "not configured for the ONU to go online" to identify whether there is an unconfigured ONU access, and the ONU service needs to be activated. The method for determining whether the monitored trap message is a preset reminder message may be determined by using an object identifier (Object Identifier, OID for short) in the trap message to determine whether it is a preset reminder message.

When the trap message is a preset reminder message, the preset reminder message is obtained, and the optical network device is configured according to the preset reminder message, the preset configuration information database, and the northbound interface protocol provided by the network element management system. The northbound interface protocol commonly used in the PON system in the related art includes, for example, a transaction language (Transaction Language-1, TL1 for short) and a Man-Machine Language (MML), for example, an application. (Application, referred to as: APP), Common Object Request Broker Architecture (CORBA), Extensible Markup (Extensible Markup) Language, referred to as XML), for example, includes Simple Object Access Protocol (SOAP) or Internet Service Application (Web Service). In practical applications, when configuring an optical network device, choose which northbound interface protocol to use to select which protocol the EMS supports in the current PON system.

Because the service automatic activation system does not deploy the PON system, the service automatic activation system generates the work order. Therefore, the technical solution provided by the embodiment of the present invention uses the ONU to access the OLT, and receives the reminder message and the preset configuration. The information is configured on the ONU to enable ONU services.

The processing sequence of the Trap message can be set as needed. For example, when the trap message is a preset reminder message, in order to ensure that the ONU service can be preferentially executed, the trap message can be placed in the high priority processing queue, so that a large amount of time is received in the EMS system. The trap message can be processed preferentially when the trap message is sent. When the trap message is not the preset alarm message, the trap can be placed in the low priority processing queue. When the EMS system receives a large number of trap messages in a short period of time, the trap in the low priority processing queue is processed. The message will be suspended.

The optical network unit service provisioning method provided by the embodiment of the present invention monitors a Trap message reported by the optical line terminal to the network element management system in the passive optical network system, and determines whether the intercepted Trap message is a preset reminder message. The preset reminder message is that the optical line terminal detects the Trap message that is reported after the unconfigured optical network unit accesses the optical line terminal; when the Trap message is the preset reminder message, according to the preset reminder message, The configuration information base and the northbound interface protocol provided by the network element management system configure the optical network unit; in the embodiment of the present invention, the northbound interface provided by the network element management system is provided according to the preset preset reminder message, the preset configuration information database, and the network element management system. The protocol automatically configures the optical network unit to complete the opening of the optical line unit service. It does not require the user to manually configure the optical network unit with the configuration, thereby automatically opening the ONU service and improving the efficiency and accuracy of the ONU service provisioning.

Optionally, as shown in FIG. 2, it is a schematic flowchart of another optical network unit service provisioning method according to an embodiment of the present invention. On the basis of the foregoing embodiment shown in FIG. 1, the embodiment implements the implementation of the optical network unit according to the preset reminding message, the preset configuration information database, and the northbound interface protocol provided by the network element management system. The detailed description is that the step 130 in this embodiment may include steps 131 to 132:

Step 131: Create a work order according to the preset reminder message, the preset configuration information database, and the northbound interface protocol.

Step 132: Send the work order to the network element management system, so that the network element management system sends corresponding data to the optical network unit according to the configuration information included in the work order, and configures the optical network unit.

The purpose of creating a work order in this embodiment is to simulate a service automatic activation system generated by a common PON system to generate a work order, so that the OLT can generate a work order according to the reminder message and the configuration information base even if the service is not automatically activated by the OLT. When a work order is created, it is created according to the format of the northbound interface protocol provided by the EMS, so that the created work order can be sent to the EMS through the northbound interface of the EMS. The work order types created by the different northbound interface protocols are different. When the TL1 protocol is used, the created work order is in the form of the TL1 command set. When the Web Service protocol is used, the created work order is in the form of an XML file.

After the work order is created, the northbound interface of the EMS is sent to the EMS system. After the EMS receives the work order, the EMS configures the ONU according to the configuration information contained in the work order, that is, the ONU service is enabled.

For example, when the northbound interface protocol provided by the EMS is the TL1 protocol, the work order generated at this time is the command set of the TL1, and the command set includes the steps of opening the ONU service, and then sends the TL1 command set to the EMS system, when the EMS system receives After the TL1 command is executed, the TL1 command in the TL1 command set is executed. The ONU is configured to complete the ONU service.

The optical network unit service provisioning method provided by the embodiment of the present invention creates a work order according to a preset reminder message, a preset configuration information database, and a northbound interface protocol format, and then sends the work order to the network element management system, so that the network is The meta-management system can configure the optical network unit according to the received work order to complete the automatic opening of the ONU service.

Optionally, in the embodiment of the present invention, the preset configuration information database may include a preset service provisioning type rule base and a preset service provisioning configuration file library.

As shown in FIG. 3, it is a schematic flowchart of a step 131 in the optical network unit service provisioning method provided in the embodiment shown in FIG. The implementation of the step 131 in this embodiment may include the following steps, that is, steps 1311 to 1314:

Step 1311: Parse the preset reminder message, and obtain device information of the optical network unit included in the preset reminder message.

Step 1312: Search for a preset service opening type rule base, and determine a service opening type corresponding to the acquired device information, where the preset service opening type rule base includes a correspondence between the device information and the service opening type.

Step 1313: Search for a preset service provisioning configuration file library, and determine a service provisioning configuration file corresponding to the acquired device information, where the preset service provisioning configuration file library includes a correspondence between the device information and the service provisioning configuration file.

Step 1314: Create the work order according to the obtained device information, the determined service opening type, and the determined service provisioning configuration file according to the format of the northbound interface protocol.

In the embodiment, the preset configuration information database includes a preset service opening type rule base and a preset service provisioning configuration file library, wherein the preset service opening type rule base includes device information of the ONU, and the ONU can The service type is activated. For example, when the ONU device is a broadband access device of a certain cell, the type of provisioning is 8M broadband service. The preset service provisioning configuration file library is composed of a plurality of service provisioning configuration files, and each service provisioning configuration file includes device information of the ONU and a configuration method of the ONU. The above service opening type rule base and business provisioning configuration file library can be defined in the system in advance as needed.

When the preset reminder message is received, the preset reminder message is obtained and parsed, and after the preset reminder message is parsed, the device information of the ONU in the preset reminder message can be obtained, and the “ONU is not configured online”. The Trap message includes the physical identification information of the ONU, such as a Media Access Control (MAC) or a Serial Number (SN), or Other information about the ONU, such as the type of ONU. The device information of the ONU is obtained according to the device information, and the service provisioning type corresponding to the device information, and the service provisioning configuration file corresponding to the device, and the device can be identified when the work order is generated. In the actual application, one of the device information in the reminder message is selected to generate a work order, which can be selected as needed.

After the device information of the ONU is obtained, the preset service opening type rule base is searched for, the service opening type corresponding to the ONU is determined, and the preset service provisioning configuration file library is searched for, and the service provisioning configuration file corresponding to the ONU is determined. Device information, service provisioning type, and service provisioning configuration The file creates a work order according to the format of the northbound interface protocol provided by the EMS. In an actual application, the embodiment does not limit the execution sequence of the step 1312 and the step 1313, that is, the sequence between the step 1312 and the step 1313 may be interchanged, or the service provisioning configuration file corresponding to the ONU may be determined first, and then the corresponding ONU is determined. Business opening type.

For example, when the northbound interface protocol provided by the EMS is the TL1 protocol, the corresponding TL1 command set is generated according to the format of the TL1 protocol, the device information of the ONU, the service provisioning type corresponding to the ONU, and the service provisioning profile corresponding to the ONU.

The optical network unit service provisioning method provided by the embodiment of the present invention obtains the device information of the ONU to be configured, and determines the service opening type and the service provisioning configuration file corresponding to the ONU according to the new information of the device, and then A work order is created in the format of the northbound interface protocol provided by the EMS, so that the OLT can call the northbound interface of the EMS to send the work order to the EMS. After the work order is received by the EMS, the ONU service is configured according to the work order, and the ONU service is automatically implemented. Opened.

Optionally, as shown in FIG. 4, another schematic flowchart of step 131 in the optical network unit service provisioning method provided in the embodiment shown in FIG. 2 is shown. On the basis of the embodiment shown in FIG. 3, the implementation manner of step 131 in this embodiment may further include step 1315 after step 1311:

Step 1315: Match the obtained device information with the legal device information included in the preset legal device information list, and determine whether the acquired device information exists in the preset legal device information list; if the determination is yes, When the obtained device information exists in the preset legal device information list, step 1312 is performed;

The preset legal device information list in the embodiment is a device information list that is pre-imported into the EMS system, and the information list includes device information of multiple ONUs. You can control whether only the licensed device can open the ONU service by determining whether the obtained ONU device is in the preset legal device information list.

For example, the device information provided by the operator can be entered into the legal device information list. Only when the ONU provided by the operator accesses the OLT, the ONU service is allowed to be enabled. Otherwise, the ONU service is refused to ensure the security of the network.

When the device information exists in the preset legal device information list, the ONU service is allowed to be opened, and the service opening type rule base corresponding to the ONU is searched for, and the service provisioning configuration file corresponding to the ONU is determined, and then according to the ONU. The device information, the service provisioning type corresponding to the ONU, and the service provisioning profile corresponding to the ONU create a work order according to the format of the northbound interface protocol.

When the device information does not exist in the preset and legal device information list, it indicates that the ONU service may not be enabled at this time. In this case, the work order can be prohibited from being generated, and the unknown EMU is notified to the OLT to try to access the OLT. .

After the optical network unit service provisioning method is provided in the embodiment of the present invention, after the device information of the ONU to be configured is obtained, the device information is matched with the device information in the preset legal device information list to determine whether it is in the device. When the device information is in the legal device information list, the step of obtaining the service opening type of the ONU according to the device information and the service opening type rule base is performed, so that only the licensed ONU can access the network and complete the configuration, so that While the ONU service is automatically opened, the security of the network is also guaranteed.

Optionally, as shown in FIG. 5, it is a schematic flowchart of another method for opening an optical network unit service according to an embodiment of the present invention. On the basis of the embodiment shown in FIG. 1 , after the step 130, the method provided in this embodiment may further include the following steps, that is, steps 140 to 160:

Step 140: Query the configuration state of the optical network unit.

Step 150: When the configuration state of the optical network unit is a configuration success state, management is performed on the network element. The system feeds back the notification message that the service is successfully opened;

Step 160: When the enabled state of the optical network unit is a configuration failure state, obtain a failure reason for the configuration failure, and feed back, to the network element management system, a notification message that includes the failure reason.

In this embodiment, the configuration state of the optical network unit is queried to understand whether the ONU service has been enabled. When the ONU has been configured, the EMS feeds back the notification message that the service is successfully opened. When the ONU configuration is not successful, the configuration fails. The reason is that the EMS feeds back a notification message that includes the reason for the failure, and the notification message is used to indicate that the ONU configuration fails, and includes the reason for the failure, so that the network operation and maintenance personnel can perform fault diagnosis.

For example, after the EMS executes all the TL1 commands in the TL1 command set, you can determine whether the ONU configuration is completed by querying whether the TL1 commands in the TL1 command set are all executed. When the TL1 commands in the TL1 command set are all executed, the configuration is complete. If the command in the TL1 command set fails to execute at least one TL1 command, the configuration is unsuccessful. When the configuration succeeds, the EMS feeds back the configuration success message. When the ONU configuration is unsuccessful, the TL1 command fails to be executed. The reason for the failure of feedback when TL1 fails, for example, may be an error message, and the error message is placed in a notification message to be reported to the EMS.

The optical network unit service provisioning method provided by the embodiment, by querying the configuration state of the optical network unit, and feeding back to the EMS, the optical network unit is configured successfully or fails to be configured, so that after the optical network unit service is successfully opened or automatically opened, The network maintenance personnel can obtain the status of the ONU service provisioning through the EMS, and feed back the failure reason of the configuration failure to the EMS, so that the network maintenance personnel can perform fault analysis for the ONU service failure.

The invention also provides an optical network unit service opening device, as shown in FIG. 6 , which is a schematic structural diagram of an optical network unit service opening device according to an embodiment of the present invention.

The configuration module 30 is configured to: when the determining module 20 determines that the Trap message is a preset reminder message, according to the preset reminder message, the preset configuration information database, and the northbound interface protocol configuration provided by the network element management system. Optical network unit.

The optical network unit service provisioning device provided by the embodiment of the invention is used for opening an optical network unit (ONU) service in a passive optical network system. When the ONU is configured, the ONU service is activated. The passive optical network system may include an element management system (EMS), an ONU, and an optical line terminal (OLT). The EMS is used as a network element management system to obtain an OLT message, and sends data to the OLT, where the OLT is used to connect the optical fiber. The ONU of the trunk device of the trunk line, an OLT can be connected to multiple ONUs, and the ONU is a terminal device installed by the client.

Optionally, in the embodiment of the present invention, the monitoring module 10 monitors the Trap message reported by the OLT to the EMS in the PON, and refers to all the Trap messages reported by the OLT to the EMS. The preset reminder message is a trap message that the OLT detects the unconfigured ONU and reports it to the EMS when the unconfigured ONU accesses the OLT. Generally, after the unconfigured ONU is installed and powered on, the OLT detects the ONU device and reports a trap message to the EMS that the content of the ONU is not configured. Therefore, it is determined that the Trap message sent by the OLT to the EMS is "not configured for the ONU to go online" to identify whether there is an unconfigured ONU access, and the ONU service needs to be activated. The method for determining whether the monitored trap message is a preset reminder message may be determined by using an object identifier (OID) in the trap message to determine whether it is a preset reminder message.

When the trap message is a preset reminder message, the preset reminder message is obtained, and the optical network device is configured according to the preset reminder message, the preset configuration information database, and the northbound interface protocol provided by the network element management system. The northbound interface protocols commonly used in PON systems in the related art include, for example, TL1, MML (the MML is, for example, APP), CORBA, XML (the XML includes, for example, SOAP/WebService), and the like. In practical applications, when configuring an optical network device, choose which northbound interface protocol to use to select which protocol the EMS supports in the current PON system.

The processing sequence of the Trap message can be set as needed. For example, when listening When the Trap message is a preset reminder message, the Trap message can be placed in the high priority processing queue in order to ensure that the ONU service is enabled in a timely manner, so that when the EMS system receives a large number of Trap messages in a short time, The trap message is processed preferentially. When the trap message is not the preset alarm message, the trap can be placed in the low priority processing queue. When the EMS system receives a large number of trap messages in a short period of time, the trap in the low priority processing queue is processed. The message will be suspended.

The optical network unit service provisioning apparatus provided by the embodiment of the present invention monitors a trap message reported by the optical line terminal to the network element management system in the passive optical network system, and determines whether the intercepted trap message is a preset reminder message. The preset reminder message is that the optical line terminal detects the Trap message that is reported after the unconfigured optical network unit accesses the optical line terminal; when the Trap message is the preset reminder message, according to the preset reminder message, The configuration information base and the northbound interface protocol provided by the network element management system configure the optical network unit; in the embodiment of the present invention, the northbound interface provided by the network element management system is provided according to the preset preset reminder message, the preset configuration information database, and the network element management system.
