Determining whether IP is granted, If assigning an IP address, assigning an IP address based on the location and cable modem class of the cable modem, receiving the cable modem IP address issuing log, and by DHCP server / date Classifying by size / size, extracting the presence of abnormality of subscriber information and unregistered subscriber equipment information through analysis of the log and notifying the management server, and databaseing information excluding the cable modem IP address issuing log of the DHCP server Step, system operation statistics, log analysis result information, subscriber terminal SNMP collection information, cable modem automatic upgrade Upgrade and querying a reset request distribution, the current state of the user, and is characterized to include steps to verify and control the main functions of the subscriber management system with administrator browser over HTTP and the Web interface.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

2 schematically illustrates the configuration of the optical coaxial mixed network subscriber management system according to the present invention.

As shown in Fig. 2, the optical coaxial mixed network subscriber management system 200 inquires whether the subscriber of the HFC service providing ISP, and the DHCP server (202) and the DHCP server ( In response to the inquiry of 202), the central authentication server (LDAP) that checks whether the subscriber is authenticated and the IP is granted, receives the cable modem IP issuance log from the DHCP server, and analyzes and stores them by DHCP server, date, and size. A log server 206, a management server 205 in charge of various management functions other than the functions of the log server 206, and a web server 207 capable of checking and controlling the main functions of the subscriber management system 200. It includes.

The DHCP server 202 in the subscriber management system 200 according to the present invention queries the central authentication server (LDAP) whether to give the cable modem 204 an IP address. When assigning an IP address, assign an appropriate IP address based on the location of the cable modem and the cable modem class. In addition, DHCP server 202 initiates a DHCP assignment process by generating a DHCP request from the underlying equipment of cable modem 204, such as a PC or VoIP, through CMTS or directly into DHCP server.

The most important function of the DHCP server 202 is "IP address assignment," but one of the equally important factors for the service provider is "policy." The DHCP server 202 collects the policy of the assigned IP scope, the common policy defined by the class of the cable modem, and the policy defined individually for each cable modem.

This policy is expressed in the form of options from the DHCP perspective.

For example, DHCP options include a list of IP lease times, netmasks, gateway addresses, domain names, and name server addresses. In the case of IP lease time, the policy differs between the cable modem and the user's PC, such as 7 days (604800 seconds) for the cable modem and 1 hour (3600 seconds) for the user's PC.

The management server 205 is composed of a management agent and related utilities that interoperate with all the systems constituting the storage database and subscriber automation system.

First, it communicates with the cron script of the DHCP agent installed in the DHCP server 202 to receive the following information.

■ DHCP IP Scope Configuration Information File

■ Current IP Usage

■ Process operation status in DHCP server

■ DHCP Request Status by DHCP Server

■ abnormal equipment information

■ Unregistered Modem Information

In addition, the management server 205 collects data from the DHCP server 202, the log server 206, and an ESS server (not shown) to generate new data or take appropriate action accordingly.

For example, if user cable modem changes occur from the ESS server, and those changes require a reset of the cable modem, the cable modem reset request process of the management server 205 may look up the database and apply the cable modem to that cable modem. If the SNMP information has been received from the DHCP server, a request is sent to the cable modem SNMP reset daemon of the DHCP server 202 with the corresponding IP information. Record the results of the response to the request again.

In addition, the management server 205 sends a warning mail when any of the DHCP process, the TFTP process, and the DHCP agent process of the DHCP server 202 receives a report, and receives a request from the web server 207 in the database. It also performs a relay role of returning a lookup result of or passing the message back to the web server 207 by transferring a message to the DHCP server 202 instead.

The management server 205 manages a plurality of DHCP servers, trouble management, subscriber inquiry, service change request processing history inquiry, cable modem management, and server performance and statistics.

The DHCP management function of the management server 205 includes IP usage statistics and analysis functions, and the failure management of the management server 205 monitors operation states of a plurality of DHCP servers, log servers, web servers, and central authentication servers. And manage current fault and fault history.

In addition, the subscriber inquiry of the management server 205 manages the subscriber's service use and cable modem status, the cable modem management includes the unregistered modem inquiry and the abnormal equipment inquiry, and the server performance / statistical function is the optical coaxial mixed network subscriber. Configuration of management system includes server performance / statistics, daily operation status, and subscriber processing statistics.

The log server 206 receives the IP issue log from the DHCP server 202 every minute and performs the following function.

■ Arrange file size units by date per DHCP server

■ Analyze logs and create files in a format that is easy to search

■ calculate IP request rate per DHCP server and notify management server (205)

■ Notify IP request rate calculation and management server 205 for each unit of time

■ Notify unregistered modem information extraction and management server (205)

■ Periodic backup of the DHCP server's configuration information

As mentioned above, the management server 205 and the log server 206 are responsible for the "management / control" function of determining data collection / analysis / operation.

The web server 207 is composed of web server software and CGI scripts in PHP format. When the operator accesses the web server 207 of the subscriber management system through the web browser, all requests are sent to the management server 205, and the management server processes the request directly or sends the request data to the central authentication server, log server, and DHCP. The server asks the server to perform an operation and the management server receives the result and sends it back to the web browser.

In the subscriber management system according to the present invention, the web server 207 performs only a "presentation" function, and all logic is contained in the management agent on the management server 205.

3 illustrates a method of managing an optical coaxial mixed network subscriber according to an embodiment of the present invention.

Referring to FIG. 3, the central authentication server 201 is queried whether the DHCP server 202 gives the cable modem an IP address (S301).

Based on the cable modem information, the central authentication server 201 confirms whether or not the IP address is given by the query of the DHCP server 202 (S302).

If the IP address is confirmed, an IP address is given based on the location of the cable modem and the cable modem class (S303).

Receive the cable modem IP address issuing log and classify by DHCP server / date / size, and extract abnormal subscriber equipment information through analysis of the classified information and notify the management server (S304).

The management server databases the information excluding the cable modem IP address issuance log of the DHCP server 202 (S305).

The operation statistics information of the system, log analysis result information, subscriber terminal SNMP collection information, cable modem automatic upgrade and reset request distribution, and the current user status are inquired (S306).

Through the HTTP and the web interface in the web server 207, the administrator checks, controls and terminates main functions of the subscriber management system using only a browser (S307).
