Description

A method of business distribution

technical field

The invention relates to the technical field of computer networks, in particular to a method for service distribution.

Background technique

With the rapid development of home network broadband services, on the basis of meeting the basic access function requirements of ordinary home users, the service types of customer premise equipment (Customer Premises Equipment, CPE) continue to expand, and there are voice, video or other high-level network data Serve.

With the continuous enhancement of CPE functions, the configuration requirements of CPE are also becoming more and more complicated. Before using it, users must complete a large amount of service data configuration work on CPE to ensure that CPE can provide network services correctly and stably. This places very high demands on the end user. In order to lower the threshold for using network services and simplify the initial configuration process for users, operators initially adopted the method of training professional installers to provide on-site service or providing telephone configuration guidance through the call center to help users complete the CPE service provisioning process. Due to the large number of CPEs and different levels of user operations, this method requires a lot of labor, and operators must pay a lot of costs for this. To solve this problem, various network equipment suppliers have proposed solutions for CPE automatic service provisioning.

In various automatic service provisioning schemes, identifying the legitimacy of users is the key to complete automatic service provisioning. At present, most automatic service provisioning solutions are based on the X Digital Subscriber Line (X Digital Subscriber Line, xDSL) access technology. The network model of xDSL is shown in Figure 1, and network elements not related to service provisioning are not shown in Figure 1. The CPE101 is connected to the digital subscriber line access multiplexer (DSL Access Multiplexer, DSLAM) 102 in the access network through independent physical lines and access ports, and the DSLAM 102 is connected to the core network; the access authentication server in the access network (BAS) 103 is connected with DSLAM 102 and Dynamical Host Configure Protocol (DHCP) server 104, and provides CPE 101 with point-to-point protocol (Point to Point Protocol over Ethernet, PPPoE) mode and DHCP mode access authentication on Ethernet; Network elements connected to the core network and related to CPE service provisioning also include an automatic configuration server (AutoConfiguration Server, ACS) 105, an operation support system (Operate Support System, OSS) 106, and a user database (DB) 107, wherein the OSS and DB connected.

In the xDSL access mode, each user has an independent physical line and access port, so identifying the line or port is equivalent to identifying the user. Before the service is released, the CPE user must first apply to OSS for xDSL service through the front desk of the operator's business hall, the Internet or telephone. The user must provide at least the Public Switched Telephone Network (PSTN) telephone number and the business type of the application service; after OSS accepts the user's application, it will provide the user with an application receipt including at least the user account and password for PPPoE access authentication, and bind the user account with the user's physical port address information on the DSLAM The relationship notifies the BAS to send the user's service data to the DB. The user's service data includes the PSTN telephone number applied by the user, the physical port address information of the user on the DSLAM, and the service data applied by the user; and notifies the DSLAM to start the user link.

Under the above preconditions, an uplink CPE service distribution method in an xDSL access line in the prior art is shown in Figure 2, including the following steps:

Step 201: CPE and DSLAM complete the negotiation of permanent virtual circuit (Permanent Virtual Circuit, PVC) link and establish PVC link;

Step 202: The CPE sends a DHCP discovery (discover) message to the DSLAM, which at least includes the information of the CPE equipment such as the Organizationally Unique Identifier (Organizationally Unique Identifier, OUI) and the product serial number, and the information is carried by the Option60 information body ; For definitions of the Option60 information body and other Option information bodies mentioned below, please refer to protocol documents such as RFC 1533 or RFC 2132. The combination of the OUI and the product serial number is called a device unique identifier, and a device unique identifier corresponds to a unique CPE device.

Step 203: The DSLAM adds the physical port address information of the CPE in the received DHCP learning message, the physical port address information is carried by the Option82 information body, and then sends the DHCP learning message to the DHCP server;

Step 204: After receiving the DHCP learning message, the DHCP server sends a query request to the DB to check whether the port is allowed to issue services according to the reported physical port address information, and the query request also includes the unique device identifier of the CPE;

Step 205: After the database receives the query request, it searches the stored user service data according to the physical port address information in the query request, whether there is the same physical port address information, if yes, the physical port has applied for xDSL service, then Return the successful result of the query to the DHCP server, and store the unique device identifier of the terminal in the user service data, otherwise return a query failure message and exit this process; the branch of the query failure in this step is not drawn in Figure 1;

Step 206: The DHCP server returns a DHCP learning response message to the CPE, in which the Option43 information body carries the ACS address;

Step 207: the DHCP server assigns the terminal address of the CPE in a DHCP manner;

Step 208: The CPE sends a registration request to the ACS, and the request includes the unique device identifier of the CPE;

Step 209: The ACS uses the received unique device identifier of the CPE as an index to retrieve user service data and physical port address information in the DB;

Step 210: DB generates a retrieval response message, which includes user service data and physical port address information, and returns the retrieval response message to the ACS;

Step 211: ACS generates a CPE configuration file according to the user service data in the retrieval response message;

Step 212: The ACS sends the generated configuration file to the corresponding CPE according to the physical port address information;

Step 213: The CPE applies the configuration file received, and completes the PPPoE account verification process with the BAS;

Step 214: The CPE returns a response message of correct configuration to the ACS, successfully completes service provisioning and exits this process.

In the above-mentioned service provisioning process, before the service provisioning, the DB has stored the physical port address information of the CPE, and the DSLAM receives the DHCP learning message from the CPE, and adds the corresponding physical port address of the CPE on the DSLAM to the message The information is then forwarded to the DHCP server; the DHCP server queries the DB whether the corresponding physical port address information of the CPE on the DSLAM has been stored in the DB, and returns the address information of the ACS to the CPE to complete the subsequent process after confirmation. Such a process would lead to the following disadvantages:

The physical port address information of the CPE is processed in the core network, and the processing process is completely transparent to the CPE, so this information cannot be used for subsequent services that require physical locations. Composite CPE integrates multiple services, and different services often use different background support systems. It is very difficult to share CPE physical port address information among different background support systems.

Contents of the invention

In view of this, the object of the present invention is to propose a method for service provisioning, which can not only realize the automatic provisioning of CPE services, but also enable the physical port address information of the CPE used for service provisioning to be used by other services. The method comprises the steps of:

The user terminal equipment CPE accesses the multiplexer DSLAM through the digital subscriber line to send a DHCP acknowledgment message to the Dynamic Host Configuration Protocol DHCP server; after the DHCP server receives the DHCP acknowledgment message, it returns a DHCP acknowledgment response message to the DSLAM. Add the physical port address information of the CPE to the DHCP learning response message, and then send the DHCP response message to the CPE; the CPE obtains its own physical port address information, and sends a registration request including the physical port address information of the CPE to the automatic configuration server ACS;

According to the physical port address information in the registration request, the ACS obtains the user's service data by searching the preset correspondence table between user service data and physical port address information, and generates a CPE configuration file according to the obtained service data. The generated configuration file is sent to the CPE;

The CPE applies the received configuration file to complete the service provisioning process.

After sending the DHCP response message to the CPE, the method further includes: the CPE deletes the physical port address information from the DHCP response message, and then sends the DHCP response message to the end user terminal.

The returning the DHCP learning response message to the DSLAM is: returning the DHCP learning response message carrying the ACS address information to the DSLAM;

Then, the CPE sending the registration request to the ACS is: the CPE sends the registration request to the ACS according to the ACS address in the received address response message.

Adding the physical port address information of the CPE to the received DHCP learning response message by the DSLAM is as follows: The DSLAM adds the physical port address information of the CPE carried in the Option82 message body to the received DHCP learning response message.

The registration request sent by the CPE includes:

The CPE sends a registration request including physical port address information to the DSLAM;

The DSLAM judges whether the physical port address information in the registration request is consistent with the physical port address information actually corresponding to the CPE, and if so, sends the registration request to the ACS; otherwise, returns a prompt that the physical port address information is wrong to the CPE and exits the process.

The registration request further includes the unique device identifier of the CPE;

According to the physical port address information in the registration request, the ACS searches the preset correspondence table between user service data and physical port address information, and before obtaining the user's service data, further includes: ACS judging the received registration Whether the unique device identifier in the request is valid, if so, perform the next steps, otherwise, return an authentication failure prompt message to the CPE and exit this process.

Wherein, the unique identifier of the device is an organization unique identifier OUI and a product serial number.

After the ACS obtains the service data of the user, it further includes:

The ACS inquires whether the user service data corresponding to the obtained user service data is stored in the user database. If there is, the DB returns the corresponding user service data to the ACS. Otherwise, it returns a query failure prompt message to the CPE and exits the server. process.

The process of completing the service release includes:

The CPE and the access authentication server BAS complete the verification process of the PPPoE account on the Ethernet;

The CPE returns a configured response message to the ACS.

Preferably, the setting of the correspondence table between user service data and physical port address information is as follows: the operation support system OSS forms a static mapping relation table containing the correspondence relation between user service data and CPE physical port address information, and the formed The static mapping relationship table is sent to the ACS, and the ACS updates the local static mapping relationship table according to the received static mapping relationship table.

The physical port address information of the CPE is the physical port address information corresponding to the CPE on the DSLAM.

Before the CPE sends the DHCP learning message to the DHCP server through the DSLAM, it further includes: the operation support system OSS forms a static mapping relationship table containing the corresponding relationship between user service data and CPE physical port address information, and forms the static mapping relationship table Send it to the business server;

Then the configuration file received by the CPE application, after completing the service distribution process, further includes: the CPE sends a service request message including terminal IP address and physical port address information to the service server; after the service server receives the service request message, The corresponding user information is found through the pre-configured static mapping relationship table, and the service server provides correct services according to the found user information.

It can be seen from the above technical solutions that the physical port address information of the CPE is sent to the CPE, and the CPE submits a service provisioning application carrying the physical port address information. Find business data and form a configuration file to complete the configuration of the CPE. Through such a service delivery method, the CPE stores its own physical port address information, which can be further used by other services; and the method of the present invention does not require a DHCP server to query the DB, so there is no need for a query interface between the DHCP server and the DB. There is little need for modification of existing equipment.

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 in conjunction with the accompanying drawings and specific embodiments.

The solution of the present invention is based on the principle that the telephone number of the xDSL line, the physical port address information and the user service data are uniquely corresponding to each other. Therefore, identifying the physical port address information is equivalent to identifying the user.

The core content of the present invention is that after the OSS accepts the user's service application, it maps the user's service data to the physical port address information of the CPE, forms a static mapping relationship table between the user's service data and the CPE physical port address information, and converts the formed static The mapping relationship table is sent to the ACS and the service server; when the CPE performs access authentication, the DSLAM returns the physical port address information of the CPE to the CPE; the registration request submitted by the CPE to the ACS contains the physical port address information; The address information searches the static mapping relationship table to obtain the corresponding user service data, forms the corresponding configuration file and sends it to the CPE to complete the service provisioning. In the above scheme, since the physical port address information is managed by the DB in the prior art, it is managed by the CPE instead, and the process of data query from the DHCP server to the DB can be omitted, so there is no need for a query interface between the DHCP server and the DB .

In the technical solution of the present invention, the physical port address information is the physical port address information corresponding to the CPE on the DSLAM, including node identification, frame number/slot number/sub-slot/port number, virtual path identifier (Virtual Path Identifier, VPI ), virtual channel identifier (Virtual Channel Identifier, VCI), virtual local area network identifier (Virtual Local Area Network, VLAN), because the CPE can obtain these physical port address information, in order to ensure network security and prevent illegal users from intercepting the physical port of the CPE For address information, in a specific embodiment of the present invention, the CPE must be able to delete the physical port address information in the message before sending the network message to the end user terminal. Therefore, the CPE used in this embodiment is a CPE device certified by the operator and having the above-mentioned filtering function of the physical port address information. The authentication process may be performed by the ACS according to the unique device identifier of the CPE when accessing the application.

Before the service is released, the CPE user must first apply to OSS for xDSL service through the front desk of the operator's business hall, the Internet or telephone. After the user applies, provide the user with an application receipt including at least the user account and password for PPPoE access authentication, notify the BAS of the binding relationship between the user account and the user's physical port address information on the DSLAM, and send the user's business data to To the DB, the user service data includes the PSTN telephone number applied by the user, the physical port address information of the user on the DSLAM and the service data applied by the user; and notify the DSLAM to start the user link. In addition to the same preconditions as those of the prior art, the OSS forms a static mapping table of user physical port address information and user service data, and sends the static mapping table to the service server and the ACS, so that the network element The mapping relationship table can be searched according to the user's physical port address information to obtain user service data.

The flow of service provisioning in this embodiment is shown in Figure 3, including the following steps:

Step 301: The CPE and the DSLAM complete the negotiation of the PVC link and establish the PVC link;

Steps 302-303: the CPE sends a DHCP learn message to the DSLAM, and the DSLAM sends the received DHCP learn message to the DHCP server;

Step 304: After receiving the DHCP learning message, the DHCP server returns a DHCP learning response message, and carries the address information of the ACS in the response message, and the Option 43 information body can be used to carry the ACS address information;

Step 305: The DSLAM adds the physical port address information of the CPE to the received DHCP learning response message, and then sends the DHCP response message to the CPE. The physical port address information is carried by the Option82 information body. If the CPE needs to continue to deliver the DHCP learning response message to the end user terminal, the CPE deletes the physical port address information in the DHCP learning response message after saving the received physical port address information and transparently transmits it to the end user terminal.

Step 306: The DHCP server assigns the terminal address of the CPE in a DHCP manner, and this step is the same as the steps related to the existing service provisioning process;

Step 307: The CPE sends a registration request to the ACS, which includes the physical port address information of the CPE and the unique device identifier;

Step 308: The ACS judges whether the unique device identifier in the received registration request is legal, that is, judges whether it is the device corresponding to a device produced by a manufacturer recognized by the operator. If it is not legal, returns an authentication failure message and exits this process. If the authentication is passed, Using the received CPE physical port address information as an index, find the corresponding user service data according to the local user physical port address information and the static mapping relationship table of user service data, and query whether the corresponding user service is stored in the DB data; if successful, execute step 309, otherwise return a query failure message to the CPE and exit this process; the branch of authentication failure or query failure in this step is not drawn in FIG. 3 .

Step 309: DB returns the queried corresponding user service data to ACS;

Step 310: ACS generates a CPE configuration file according to the user service data from the DB;

Step 311: The ACS sends the generated configuration file to the CPE;

Step 312: The CPE applies the configuration file received, and completes the PPPoE account verification process with the BAS;

Step 313: The CPE returns a response message of correct configuration to the ACS, successfully completes service provisioning and exits this process.

In the above step 307, when the registration request sent by the CPE to the ACS passes through the DSLAM, the DSLAM can also compare the physical port address information actually corresponding to the CPE with the physical port address information in the registration request, and if the comparison result is consistent, perform the subsequent operations of this step If the comparison results are inconsistent, a physical port address information error message will be returned to the CPE and this process will exit. The purpose of doing this is to strengthen the authentication of the physical port address information reported by the CPE and prevent illegal users from maliciously modifying the physical port address information.

After completing the service provisioning process, when the CPE requests the service from the service server, the request message includes the terminal IP address and physical port address information. The service server finds the corresponding user information through the static mapping relationship table configured by the OSS in advance, and provides the correct service according to the found user information.

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the protection of the present invention. within range.
