Description

A service distribution method and system

technical field

The invention relates to a service distribution technology in a communication network, in particular to a service distribution method and system. the

Background technique

The current broadband access technology is mainly divided into copper wire access technology and optical access technology. The access network realized by optical access technology is called Optical Access Network (OAN, Optical Access Network). Passive Optical Network (PON, Passive Optical Network) technology is a point-to-multipoint optical access technology. the

FIG. 1 is a schematic diagram of a network structure of an existing PON system. The PON system shown in Figure 1 includes: Optical Line Terminal (OLT, Optical Line Terminal), Optical Distribution Network (ODN, Optical Distribute Network) and Optical Network Unit (ONU, Optical Network Unit). the

Among them, the OLT is connected to at least one ODN and provides a network side interface (SNI) for the OAN;

ODN is a passive optical splitting device, which is used to transmit the downlink data of OLT to each ONU through optical branching, and transmit the uplink data of ONU to OLT through aggregation;

The ONU is connected to the OND to provide the user interface (UNI) for the OAN. If the ONU also provides the function of the user port, for example, the ONU provides the Ethernet user port or the simple old telephone service user port (POTS, Plain Old Telephone Service). It is called Optical Network Termination (ONT, Optical Network Termination). In the following description, unless otherwise specified, ONU and ONT are collectively referred to as ONT. the

The ONU Management Control Interface (OMCI) is a mechanism for transmitting information between the OLT and the ONT. Through the configuration of the transmission channel through the OMCI, the management and control of the ONT by the OLT can be realized. In the OMCI mechanism, various data of ONT managed by OLT are abstracted into a Protocol-Independent Management Information Base (MIB) for short, and the basic information unit of MIB is a management entity (ME, Manage Entity). the

Service provisioning refers to: through a set of provisioning system, the operator realizes the automatic configuration process from initial user number allocation to subsequent user service refresh. The operator's service issuance system includes an order system, an operation support system (OSS), an equipment management system (EMS) and service equipment. At present, there are many PON technologies, such as Giga-bit Passive Optical Network (GPON, Broad Band PON) and Broadband Passive Optical Network (BPON, Broad Band PON). The service provisioning process in the PON system of the OMCI mechanism:

First, the operator conducts a site survey on the network, determines the physical deployment, installs the equipment, and performs the corresponding basic configuration in the EMS; then, when the user applies for a certain service from the business hall, the OSS system records the user's service information , and at the same time notify the EMS to generate data related to the user's service information; finally, the EMS sends the data to the service device side, and the service device completes the specific parameter configuration. In the whole process, except for the configuration that requires human intervention at the front desk of the business hall, the subsequent process is automatically realized by the combination of OSS, EMS, OLT, ONT and other equipment. This automatic realization process is called service provisioning. the

In the G.984.4 standard formulated by the International Telecommunication Union (ITU-T) for GPON technology and subsequent supplementary versions, the functions of the OMCI management entity are improved, so that OMCI can manage IP voice (VoIP), circuit emulation service (CES) and For value-added services such as Multimedia over Coax Alliance (MoCA), the service distribution method proposed for these value-added services is shown in FIG. 2 . Referring to Figure 2, when a user applies for a certain service, such as a VoIP service, the OSS sends the message that the user adds the VoIP service to the EMS, and the EMS downloads all configurations related to the VoIP service through MIB messages of the Simple Network Management Protocol (SNMP) one by one. Send them to ONT, and then OLT converts these MIB messages into OMCI management entity messages and sends them to ONT. Finally, ONT configures specific hardware devices in ONT one by one according to OMCI management entity messages. the

There is following shortcoming in above-mentioned technical scheme:

1. Due to the various types of terminals, the standard only stipulates the management entities of VoIP, CES, MoCA and other services, and because the OMCI management entities are relatively complex, the expansion of OMCI management entities will bring a lot of development workload ;

2. The increase of OMCI management entity messages will increase the difficulty of intercommunication between OLT and ONT equipment;

3. Any changes to the OMCI entity will involve changes to multiple links such as EMS, OLT, ONT, etc., which is not conducive to expansion. the

Therefore, the scalability of the above-mentioned existing service provisioning solution is relatively poor. the

Contents of the invention

In view of this, the service provisioning method disclosed in the embodiment of the present invention provides a service provisioning method with good scalability. the

The service provisioning system disclosed in the embodiment of the present invention provides a service provisioning system with good scalability. the

In order to achieve the above object, the technical solution of the embodiment of the present invention is specifically implemented as follows:

A service distribution method, the method includes the following steps:

The equipment management system EMS generates a corresponding configuration file according to the service information of the user, and sends the configuration file to the optical network terminal ONT corresponding to the user through the optical line terminal OLT, and the ONT configures the configuration file according to the configuration file. The hardware in the ONT is configured accordingly. the

A service delivery system, including OSS, EMS, OLT and ONT, wherein the EMS is used to generate a corresponding configuration file according to the user's service information, and send the configuration file to the user through the OLT the corresponding ONT;

The OLT is configured to send the received configuration file to the ONT;

In this way, the service configuration of the ONT is realized by using the configuration file. Since the configuration file can be expanded very flexibly, correspondingly, the service configuration information in the configuration file can also be flexibly expanded. the

In addition, because in the above technical solution, the OLT only needs to transmit the configuration file between the EMS and the ONT, and does not need to perceive the configuration, thus reducing the coupling between the EMS, OLT and ONT equipment, which also makes the service reliable. More scalable. the

Detailed ways

In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples. the

Fig. 3 is a schematic flowchart of a service provisioning method in an embodiment of the present invention. Referring to Fig. 3, this method comprises the following steps:

Step 301: The EMS obtains the service information of the user. the

In this step, the EMS may obtain the user's service information from the OSS, or from the information input by the network administrator to the EMS, or obtain the user's service information in any other feasible manner in the prior art. the

According to the prior art, when the EMS obtains the service information of the user from the OSS, it may be based on network protocols such as TL1 and Common Object Request Broker Architecture (CORBA). the

Step 302: The EMS generates a corresponding configuration file according to the user's business information. the

In this step, in order to facilitate the rapid generation of user configuration data, public configuration file templates corresponding to various ONT types can be generated in the EMS in advance according to the ONT type, and some public configuration information can be set in these public configuration file templates. In this way, when a user subscribes to a certain service, the OSS system or network administrator can only send the personalized configuration information corresponding to the service to the EMS, and the EMS will set the user's personalized configuration information in the corresponding public configuration file template to generate a configuration file corresponding to the user's business information.

Here, public configuration information refers to some conventional configuration information that can be shared by different users/ONT terminals; personalized configuration information is a concept relative to public configuration information, such as a user's phone number, routing method, etc. Or ONT-specific configuration information. the

In this step, the configuration file generated by EMS can adopt the currently more commonly used Extensible Markup Language (XML) format, and of course other formats can also be used, such as text file (TXT) format or other custom formats to generate configuration files, as long as It is sufficient that the ONT can normally parse out the configuration data after receiving the configuration file. the

In this step, after the EMS generates the configuration file, it may be stored in the EMS, or the EMS may store the configuration file in a file server. the

Here, the file server may be a file server based on a file transfer protocol (FTP), or a server based on a general file transfer protocol (TFTP), a secure file transfer protocol (FTPS) or other file transfer protocols. the

Step 303: the EMS sends the configuration file to the OLT. the

In this step, when the ONT goes online, after the OLT detects the ONT, the OLT sends the type of the ONT and the user identification (ID) to the EMS, and the EMS determines the configuration file to be issued according to the type of the ONT and the user ID. After the EMS determines the delivered configuration file, this embodiment provides two ways of sending the configuration file to the OLT. the

The first way is: EMS sends configuration files to OLT directly. the

The second method is: in step 302, the EMS stores the generated configuration file in the file server. After the EMS determines the configuration file to be issued, it notifies the OLT of the determined configuration file, and the OLT sends the file server A file download request for downloading the configuration file is initiated, and then the file server sends the configuration file requested by the OLT to the OLT. the

In this step, the EMS and OLT can exchange information such as ONT type and user ID based on SNMP, Telnet and other protocols. When transferring configuration files between EMS and OLT, FTP, TFTP, FTPS or other methods can be used. File transfer protocol method, FTP, TFTP, FTPS or other file transfer protocol methods can also be used to transfer configuration files between the file server and OLT, and FTP, TFTP can also be used to transfer configuration files between the file server and OLT method, FTPS method or other file transfer protocol methods. the

Step 304: the OLT sends the configuration file to the ONT. the

In this step, the OLT can send the configuration file to the corresponding ONT through the OMCI loading file channel. For how to use the OMCI loading file channel to send the configuration file to the ONT, please refer to the data loading process of OMCI in the prior art. Let me repeat. the

Step 305: the ONT configures the hardware in the ONT according to the configuration file. the

In this step, the ONT parses the configuration file from the OLT to obtain configuration data corresponding to the user's service information, and configures the hardware of the ONT itself according to the configuration data. the

So far, the service provisioning method of this embodiment ends. the

The specific implementation of the service provisioning system of the present invention will be described below through a system embodiment. the

Fig. 4 is a schematic diagram of the composition and structure of the service provisioning system in the embodiment of the present invention. Referring to Figure 4, the system includes: OSS, EMS, OLT and ONT. the

Among them, EMS is used to generate the corresponding configuration file according to the user's business information, and send the configuration file to the ONT corresponding to the user through the OLT;

OLT, used to send the received configuration file to ONT;

The ONT is used to configure the hardware in the ONT according to the configuration file. the

In the system shown in Figure 4, the EMS can be further used to set a public configuration file template corresponding to the ONT type and containing public configuration information, and to set the user's personality configuration information in the corresponding public configuration file template to generate the same The corresponding configuration file of the user's business information. Here, the EMS can obtain the user's business information from the OSS based on network protocols such as TL1 and CORBA, or can obtain the user's business information from the information entered by the network administrator into the EMS, or can obtain the user's business information in any other feasible way in the prior art. business information. the

In the system shown in Figure 4, the OLT can be used to detect the ONT. When the ONT goes online, the ONT type and user ID are sent to the EMS; the EMS determines the configuration file to be delivered according to the ONT type and user ID. After the EMS determines the delivered configuration file, this embodiment provides two ways of sending the configuration file to the OLT. the

The first way is: EMS sends configuration files to OLT directly. In this way, the configuration files can be transferred between the EMS and the OLT using FTP, TFTP, FTPS or other file transfer protocols. the

The second method is: further set up a file server in the system shown in Figure 4, and the EMS stores the generated configuration file in the file server. A file download request for downloading the configuration file is initiated, and then the file server sends the configuration file requested by the OLT to the OLT. In this way, the configuration file can be transferred between the file server and the OLT by means of FTP, TFTP, FTPS or other file transfer protocols. the

After receiving the configuration file, the OLT can send the configuration file to the corresponding ONT through the OMCI upload file channel. the

In the system shown in Figure 4, EMS can be used to generate configuration files in XML format, TXT format or other formats;

The ONT is used to parse configuration files in XML format, TXT format or other formats to obtain configuration data corresponding to the user's business information, and configure the hardware of the ONT itself according to the obtained configuration data. the

As can be seen from the above-mentioned embodiments, in the technical solution disclosed in the embodiments of the present invention, the EMS first generates a corresponding configuration file according to the user's business information, and then sends the configuration file to the ONT corresponding to the user through the OLT, and finally, the ONT According to the configuration file, the hardware in the ONT is configured accordingly. In this way, the service configuration of the ONT is realized by using the configuration file. Since the configuration file can be expanded very flexibly, correspondingly, the service configuration information in the configuration file can also be flexibly expanded. the

Moreover, in the above technical solution, the OLT only needs to transmit the configuration file between the EMS and the ONT, and does not need to perceive the configuration, thus reducing the coupling between the EMS, the OLT and the ONT equipment, which also makes the service available. More scalable. the

In addition, in order to facilitate the rapid generation of user configuration data, this embodiment sets corresponding public configuration file templates in the EMS according to different ONT types, so that the OSS or network administrator only needs to send the user's personalized configuration information to the EMS, EMS can generate configuration files according to these personality configuration information. the
