The present invention relates to an Internet Protocol (IP) -A / VDSL device management system, and more particularly, to eXtensible Markup Language (XML) in a subscriber network communication service configuration management system (hereinafter, TIMS: Telecom Integration Management System). The present invention relates to a technology for managing a state of an Internet protocol-A / VDSL (Asymmetric / Very high data rate Digital Subscriber Line) by interworking with an XML gateway based on the above.

As the use of the Internet by modern people increases, the penetration rate of Internet services to homes and businesses is increasing rapidly.

In order to use the Internet service by ADSL or VDSL method in general home or business place, a modem for supporting ADSL or VDSL should be installed in the PC terminal, and the data line from the PC terminal is transferred to the Digital Subscriber Line Access Multiplexer (DSLAM). After gathering and multiplexing, IP addresses are assigned through DHCP (Dynamic Host Configuration Protocol), and then connected to the Internet.

However, in this case, at the time when the PC terminal is booted, it is troublesome to perform a process of determining whether the ID and password for authentication are input through the PC terminal and matching with the registered authentication information. In addition, there is a limit that the transmission speed of ADSL can be guaranteed only when the distance between the DSLAM and the PC terminal is within a certain distance, for example, within 5 km.

The Internet Protocol-ADSL and Internet Protocol-VDSL devices were developed to solve these problems.

Internet Protocol-A / VDSL equipment is installed in a large residential complex or commercial area, and automatically collects the information of the PC terminal upon booting of the PC terminal to perform authentication on the PC terminal without intervention of the PC terminal. If this succeeds, it assigns the Internet protocol address to the PC terminal and performs the function of connecting the PC terminal to the Internet network.

In the Internet Protocol-A / VDSL device, a plurality of ports for subscriber connection are configured. The port is initially set to an active state, and if a subscriber line is connected to the port, the PC terminal can use the Internet access service. Make sure

However, in this case, even if the malicious user has not registered with the service provider, there is a problem that the Internet access service can be used by connecting his subscriber line to the port of the Internet Protocol-A / VDSL device. -A function to control the enable / disable state of a port of A / VDSL device was required.

Due to this demand, as shown in FIG. 1, TIMS provides Internet protocol through element management system (EMS) 1, 2, Telnet, or device-specific application 3 of each device (A, B). -A / VDSL equipment (A, B, C, D) is supported to control the operation status of the malicious user who has not registered to the service provider by using the above unauthorized access to the Internet service Can be excluded.

In Figure 1, A equipment EMS (1) performs only management for equipment A connected through a dedicated network, B equipment EMS (2) performs only management for equipment B, the application for each equipment is operated only for D equipment C equipment that is not managed by A equipment EMS (1), B equipment EMS (2), and application program (3) should be managed by telnet.

Therefore, in the above-described control method of the Internet protocol-A / VDSL device by TIMS, the operator must be aware of the control path of the specific Internet protocol-A / VDSL device to be accessed in advance, and the command corresponding to each control path is required. It was a hassle to manage the status of the equipment only by correctly inputting.

In this case, since TIMS operators do not input uniformly designated commands for Internet protocol-A / VDSL devices, it is difficult to know the processing method for each Internet protocol-A / VDSL device. Since the GUI (Graphic User Interface) environment is different for each A / VDSL device, it is difficult for the operator to efficiently manage the Internet Protocol-A / VDSL device.

Accordingly, the present invention has been made to solve the above-mentioned conventional problems, and configures a gateway that provides a command set and processing results for each device for an Internet Protocol-A / VDSL device, and TIMS includes all kinds of Its purpose is to provide a GUI that integrates and manages Internet Protocol-A / VDSL devices.

In addition, the present invention enhances information security by performing XML-based encrypted communication between TIMS and Internet Protocol-A / VDSL devices, and describes the interworking system between devices in XML, thus providing a foundation for accessing the operating environment through the web. In this regard, another aim is to provide flexibility in interworking standards.
