Description

Service configuration method and system for passive optical network

The present invention relates to the field of PON (Passive Optical Network) technology, and in particular, to a service configuration method and system for a passive optical network. Background technique

Passive Optical Network (PON) technology is a point-to-multipoint fiber access technology. P0N consists of optical line terminal (OLT) and optical distribution network (0DN, Optical Distribution Network). And an optical network unit (ONU, Optical Network Unit) or an optical network terminal (ONT, Optical Network Terminal) on the user side.

The PON network element management system (referred to as PON EMS) provides the northbound interface (NBI) for the user service to be opened. The PON EMS interacts with the service provider's service activation interface and the service provider's service to automatically exchange the service configuration information to meet the PON network. The need to automate the opening, teardown, suspension, recovery, modification, and transfer of voice services, broadband services, and Internet TV (IPTV) services in different scenarios. In order to simplify the ONU/ONT service provisioning process, after the user applies for the service, the installer can implement the service zero configuration when the ONU/ONT is installed on site. After the ONU/ONT is connected to the power supply, the service is immediately delivered, and the installer can immediately perform the service test. , thus enabling ONU/ONT plug and play. The general FTTH (Fiber To The Home) service is opened as follows:

1. The user accepts the business through the business hall or the customer service center, and after the resource management system's resource providing capability is confirmed, the customer order flow is generated and transferred to the service opening system;

2. After the service opening system performs order decomposition, generate a resource configuration work order to the resource management system for resource allocation;

3. If the user did not open the FTTH service, the resource management system is based on the user's installed address. Allocate the ONU/ONT device and port, and related line resources. If it is enabled, allocate the ONU/ONT port and perform preemption, and return the resource configuration information and device related information to the service provisioning system.

4. After the resource configuration is completed, the service opening system generates an automatic construction work order to the automatic activation system;

5. The automatic activation system generates a series of sub-work orders, which are dispatched to the relevant system for activation: Distribute the sub-work orders to the PON EMS. If it is a newly assigned ONU/ONT device, it needs to be performed first.

ONU/ONT configuration, then activate voice users;

Distribute the work order to the softswitch. If the ONU/ONT first activates the voice service, first add the voice device and then add the voice user.

Distribute child work orders to the Smart User Database (SHLR) to configure voice user authentication;

6. After the automatic construction is completed, the service opening system generates a manual construction work order to the construction dispatching system;

7. The construction dispatching system carries out the external line construction according to the work order information dispatcher. When the ONU/ONT is newly installed, the ONU/ONT uses the logical number LOID authentication mode, and the LOID needs to be written to the ONU/ONT device, and the other authentication mode sets the number authentication information. Return to the service opening system after the completion of the construction;

8. After the completion of the manual construction, the service opening system will be completed and notified to the resource management system for resource occupation. The product will be reported to the Customer Relationship Management (CRM) system and completed.

In the seventh step of the above process, for the FTTH type ONU/ONT, the service configuration data is sent to the PON EMS through the service configuration northbound interface of the PON EMS in step 5, and the PON EMS passes the Simple Network Management Protocol (SNMP, The Simple Network Management Protocol is delivered to the OLT. After the ONU/ONT authentication information is set, the on-site construction personnel turn on the ONU/ONT power supply. After the optical fiber is connected, the ONU/ONT service configuration data is managed from the OLT through the extended operation. Maintenance (OAM) or ONT Management and Control Interface (OMCI) channels are automatically delivered, enabling FTTH plug-and-play without manual intervention. In the FTTH scenario, most of the ONU/ONTs of the Single Home Unit (SFU) or Home Gateway Type Unit (HGU) type are used. These types of ONU/ONTs are relatively simple in the Layer 2 service configuration management part, extending OAM or OMCI support is relatively complete. The number of ports provided on the ONU/ONT is small. All configurations can be saved on the OLT. The SFU or HGU type ONU/ONT is suitable for the FTTH plug-and-play scenario.

For a multi-user residential unit (MDU), the MDU does not only include the configuration of the Layer 2 service, but also the configuration of the Layer 3 service. The service type of the MDU is not only the Ethernet service but also the network. The VoIP service also includes services such as Asymmetric Digital Subscriber Line (ADSL) and Very-high-bit-rate Digital Subscriber Loop (VDSL). OMCI does not have enough configuration interfaces for these services. In addition, the number of MDU ports is large. The configuration data of all MDUs stored in the OLT will also occupy a large amount of memory space of the OLT.

The MDU type of ONU is often used in the FTTB (Fibre to The Building) scenario. In the FTTB deployment scenario, the MDU is managed as a separate NE. The MDU device is enabled during the network deployment phase. The PON EMS directly uses the SNMP protocol to configure services for user ports on the MDU to implement service delivery.

MDU has also been widely used in the FTTO (Fiber To The Office) scenario. Many scenarios of FTTO are generally opened after the user applies for business in the business hall. The FTTB service opening method cannot meet the FTTO opening scenario. It is required that in the FTTO scenario, the same service opening method as the FTTH scenario is required, that is, the ONU is required to be provisioned with zero configuration, and the ONU is plug and play, but due to the complicated configuration of the MDU service described above, the definition of the OMA or OMCI is extended. The interface standard cannot meet the requirements of the business development. At present, it is not possible to use the FTTH scenario and open the SFU-like opening process to open the MDU.

The MDU device is generally managed as a network element in the PON network. The MDU device itself can support SNMP management. A traditional way is to receive the MDU service configuration in the PON EMS. After the work order, the data is cached on the PON EMS. After the MDU is online, the PON EMS uses the SNMP protocol to configure the service for the MDU user port. The disadvantage of this method is that the entire system relies on the MDU online Trap notification message, and the SNMP Trap notification message is an unreliable message, which is easy to be lost, and the Trap message cannot be on the NMS when a Trap message storm occurs on the network. Timely and reliable processing will affect the timely opening of the MDU. In addition, after the MDU is online, the PON EMS needs to use the SNMP protocol to configure data for all ports. A large number of SNMP operations are likely to cause SNMP commands to fail, which also affects Reliable opening to the MDU. Summary of the invention

The technical solutions of the present invention are further elaborated below in conjunction with the accompanying drawings and specific embodiments. The embodiment of the invention provides a service configuration method for a passive optical network. As shown in FIG. 1 , the method mainly includes:

Step 101: After receiving the ONU command sent by the service activation system, the PON EMS creates an ONU on the OLT (the ONU is offline).

A resource pool device for allocating an IP address to the ONU is provided on the PON EMS. After the PON EMS receives the command to create an ONU issued by the service activation system, if the command for creating the ONU carries the IP address assigned to the ONU, The PON EMS configuration management channel parameter, and the IP address carried in the management channel parameter and the command to create the ONU is sent to the OLT; if the command to create an ONU does not carry the IP address assigned to the ONU The PON EMS allocates a free IP address to the created ONU, configures a management channel parameter, and sends the IP address and the management channel parameter to the OLT. The management channel parameters include, but are not limited to, routing parameters and management channel virtual local area networks (VLANs). The OLT persists and saves the management channel parameters of the ONU.

The OLT adds a "service configuration flag" to each ONU that has been configured. After the ONU is first created, the PON EMS sends an SNMP command to mark the ONU as "unconfigured service". Optionally, the OLT can automatically mark the ONU as "not". Configure the business."

Step 102: After receiving the ONU service activation command sent by the service activation system, the PON EMS sends the service configuration information of the OLT to the OLT, and configures the service on the ONU side. The information is converted into the corresponding ONU configuration file and uploaded to the configuration file server.

The PON EMS uploads the ONU configuration file by using the file transfer protocol. The content of the ONU configuration file preferably includes only the service configuration related data received by the PON EMS from the upper layer service activation system; but may also include some default configurations, such as ONU. Configuration of access control on the other.

After the PON EMS uploads the ONU configuration file to the configuration file server, the PON EMS sends the acquisition parameters of the ONU configuration file to the OLT. The OLT device persists the parameters for saving the ONU configuration file.

Preferably, after the PON EMS creates an ONU on the OLT, the created ONU can be marked as an unconfigured service; correspondingly, when the OLT detects that the ONU is online, and determines according to the service configuration flag corresponding to the ONU, When the ONU is not configured with the service, the OLT delivers (through the extended OAM or OMCI) to the ONU corresponding to the management channel parameter and the configuration file of the ONU, and sends a command to trigger the ONU to obtain the configuration file server. The corresponding ONU configuration file. The ONU can obtain the ONU configuration file through the file transfer protocol, and each ONU has a dedicated configuration file.

Of course, after the PON EMS creates an ONU on the OLT, it may not mark whether the ONU configures the service. When the OLT detects that the ONU is online, the OLT sends the management channel parameters and the configuration parameters of the configuration file to the ONU. When the ONU determines that the service is not configured according to the self tag, the ONU obtains the corresponding ONU configuration file from the configuration file server according to the obtaining parameter.

The ONU supports the management of channel parameters by extending the OAM or OMCI configuration. It supports the configuration of the ONU configuration file by extending OAM or OMCI. It has the ability to obtain configuration files from the configuration file server and automatically load service configurations through the file transfer protocol.

After the service is loaded, the ONU sends an extended OAM or OMCI message to the OLT. If the loading is successful, the OLT sets the service configuration of the ONU as "configured service". If the OLT fails to load the service, the OLT may initiate a load request again. If the ONU fails to load within a limited number of times, the OLT sends a Trap message to the PON EMS to notify the EMS monitoring personnel to process. When the OLT detects that the ONU is online, if the service configuration flag of the ONU is "configured service", the OLT does not initiate the ONU to load the configuration request. If the ONU is replaced, the service configuration flag of the ONU needs to be set to "unconfigured service". After the new ONU goes online, you can obtain the configuration file to implement configuration loading. Preferably, the ONU supports the legal verification of the obtained configuration file. If the verification fails, the notification message is sent to the PON EMS. Optionally, the ONU supports the configuration of the post-loading notification message to the PON EMS.

The ONU loads the corresponding service according to the obtained ONU configuration file. As an implementation manner of the embodiment of the present invention, the ONU returns a file loading completion message to the OLT after the service is loaded; the OLT receives the file of the ONU. After the completion message is loaded, the ONU is marked as a configured service. As another implementation manner of the embodiment of the present invention, the ONU returns a file loading completion message to the OLT after the service is loaded, and actively marks itself as a configured service.

It should be noted that the configuration file server in the embodiment of the present invention may be disposed inside the PON EMS (that is, the PON EMS has the configuration file server function). Of course, it may also be disposed outside the PON EMS as an independent peripheral.

The service configuration method of the present invention will be further elaborated below in conjunction with specific embodiments.

In this embodiment, a File Transfer Protocol (FTP) is used as a transport protocol for a configuration file, and a PON EMS serves as a configuration file server, which provides the function of an FTP server.

The IP address pool of the ONU needs to be configured in advance on the PON EMS. The ONU can allocate a management address from the address pool. Each IP address in the address pool can only be used by one ONU. The assigned IP address cannot be repeatedly allocated. To enable the ONU to support remote management, you must also configure the management channel VLAN and routing information of the ONU. However, in general, the management channel VLAN and routing information of each ONU are the same. The FTP service is started on the PON EMS. The configured user is configured on the FTP server. The PON EMS uses this user information to upload the configuration file. The ONU uses this user information to download the configuration file.

On-site construction personnel write the ONU's authentication information to the ONU before the ONU goes online.

The whole process consists of two phases, namely the ONU non-online phase and the ONU online phase. The specific process is as follows.

The process of the ONU not online phase is shown in Figure 2, which mainly includes:

Step 201: The service activation system sends a command for creating an ONU to the PON EMS, where the command carries the necessary information that the ONU can create offline, including but not limited to the capability type of the ONU, the authentication information of the ONU, and the dynamic bandwidth allocation of the ONU (DBA, Dynamic Bandwidth Allocation ) Bandwidth template, etc.

Step 202: The PON EMS sends an SNMP command to create an ONU to the OLT, and creates an offline ONU on the OLT, and marks the offline ONU "unconfigured service". After the offline ONU is created on the OLT, the ONU is online. Can be automatically authenticated.

Step 203: After the ONU is successfully created, the PON EMS determines whether the command for creating the ONU carries the IP address assigned to the ONU. If it is carried, the PON EMS configures the management channel parameter, and sets the management channel parameter and the command for creating the ONU. The IP address carried in the OLT is delivered to the OLT. If the command to create an ONU does not carry the IP address assigned to the ONU, the PON EMS allocates an idle IP address to the ONU and configures the management channel parameters. The assigned IP address and management channel parameters are sent to the OLT, and the OLT persists these configuration parameters on the OLT. The management channel parameters include but are not limited to routing parameters and management channel VLANs.

Step 204: The PON EMS returns a successful ONU response to the service activation system.

Step 205: The service activation system sends the service configuration data of the ONU (that is, the ONU service activation command, and the service is required to be configured for the ONU), and the service may include the common Internet service and the IPTV multicast. One or more of business and voice services.

Step 206: The PON EMS parses the service activation command delivered by the service activation system. Step 207: The PON EMS sends the service configuration information of the OLT to the OLT by using an SNMP command. The service configuration information of the OLT is obtained from the service activation command sent by the service activation system.

Step 208: The PON EMS creates service configuration information of the ONU, and converts the service configuration information of the ONU into a corresponding ONU configuration file, and then uploads the information to the FTP server.

Step 209: The PON EMS sends the parameters of the ONU configuration file to the OLT, where the obtaining parameters include at least: an IP address of the FTP server, an FTP user name, an FTP password, a file name, and a file relative path. The OLT persists these parameters.

Step 210: The PON EMS returns a configuration service success response to the service activation system.

The process of the ONU online phase is shown in Figure 3, which mainly includes:

Step 301: The ONU is powered on, and registration and authentication are completed.

Step 302: The OLT detects that the ONU completes registration and authentication, and sends the management channel parameter to the ONU by extending the OAM or OMCI interface.

Step 303: The OLT sends the parameters of the ONU configuration file to the OLT by extending the OAM or the OMCI interface, where the obtaining parameters include at least: an IP address of the FTP server, an FTP user name, an FTP password, a file name, and a file relative path.

Step 304: The OLT determines that the ONU is not configured with a service, and sends an ONU to the ONU by extending the OAM/OMCI interface, and triggers the ONU to perform service loading.

It should be noted that, as another implementation manner of the embodiment of the present invention, the step 304 may be performed before the step 302, that is, when the OLT determines that the ONU does not configure the service, step 302-303 and subsequent processes are performed. When the OLT determines that the ONU has configured services, steps 302-303 and subsequent processes are not performed.

Step 305: The ONU functions as an FTP client, and logs in to the configuration file server to obtain a configuration file. Pieces.

Step 306: The ONU performs file verification, and loads the service configuration from the configuration file. Step 307: The ONU reports the file loading completion message to the OLT by extending the OAM/OMCI interface.

Step 308: The OLT sets the service configuration flag of the corresponding ONU to "configured service".
