Description

Upgrade service system in digital subscriber line network {UPGRADE SERVICE SYSTEM IN DIGITAL SUBSCRIBER LINE NETWORK}

The present invention relates to a Digital Subscriber Line (DSL) network, and more particularly to a service for upgrading the software of a subscriber device.

DSL, commonly referred to as "xDSL", is a high-speed modem (modulator-demodulator) (MODEM) technology that is being pushed to meet the needs of the large-scale high-speed Internet access market. It is a public network technology that supports broadband at a limited distance by using. These xDSLs include Asymmetric Digital Subscriber Line (ADSL), High-bit-rate Digital Subscriber Line (HDSL), Single-line Digital Subscriber Line (SDSL), Single-Pair High_Speed Digital Subscriber Line (SHDSL), and Universal Digital Subscriber Line (UDSL). ), And various DSL services such as a very high-data-rate digital subscriber line (VDSL).

If you want to use the DSL as described above, you must subscribe to a DSL service provider and have an internal or external DSL modem in a personal computer (PC) as a subscriber device.

Referring to FIG. 1 showing a typical ADSL network as an example of the DSL, an ADSL modem (ADSL Transceiver Unit_Remote), which is ATU-R (ADSL Transceiver Unit_Remote), is connected to a PC 100 by a 10 base-T line. 102 is connected to a telephone line 106 that is wired to a Digital Subscriber Line Access Module Central-Office Modem Pool (DSLAM) 108, which is an ADSL Transceiver Unit-Central (ATU-C) located at an operating station. A filter 104 is provided between the ordinary telephone and the telephone line 106 to separate the ADSL signal and the signal according to the ordinary telephone. The DSLAM 108 is connected to a Network Attached Storage (NAS) 112 via a Synchronous Transport Module-1 (STM-1) line 110, which is a synchronous transmission line, and the NAS 112 is connected via a 100 base-T line. Gigabit switch 114, which is connected to the Internet 120 via a Gigabit Switch Router (GSR) 118 via a gigabit interface line. The DSLAM 108 aggregates signals of a general telephone frequency band received from subscriber devices, decompresses aggregated ADSL frames, converts them into packet data for a corresponding destination, and transmits them through the STM-1 line 110. Then, the received packet data is bundled for each subscriber, and an ADSL frame is generated for each subscriber and transmitted to the ADSL modem 102 of the subscriber. When the subscriber 112 attempts to connect by entering an ID and password through the PC 100, the NAS 112 authenticates whether the subscriber is an ADSL subscriber by using the ID and password, and the switch 114 receives from the authenticated subscriber. The packet data is transmitted to the Internet 120 through the GSR 118, and the packet data received from the Internet 120 is transmitted to the corresponding DSLAM 108 through the NAS 112. In addition, the switch 114 is connected to the element management system (EMS) 116 that performs management for operation maintenance, NAS 112 and the switch 114 and EMS 116 is an Internet service, such as Kornet (Kornet) Corresponds to the central office of the provider (hereinafter referred to as "ISP").

There is a case that a modem of a subscriber device receiving a DSL service and a driver, which is a connection related software, are upgraded due to performance improvement while accessing a DSL network such as the ADSL network. In this case, if the driver of the subscriber device is not upgraded to the best version, the subscriber may not be provided with the improved service and an error may occur. This may cause inconvenience to the subscriber or cause dissatisfaction of the subscriber. Therefore, an upgrade version of the driver file must be installed on the subscriber device. To this end, after-service (A / S) personnel may visit and install the subscriber's premises, but this is difficult in practice. In addition, even if the subscriber installs directly, it causes inconvenience to the subscriber.

Accordingly, an object of the present invention is to provide an upgrade service system capable of automatically remotely upgrading a driver of a subscriber device.

Another object of the present invention is to provide an upgrade service system in which a subscriber can remotely upgrade a driver of a subscriber device through a web.

The upgrade service system of the present invention for achieving the above object comprises an upgrade server having a driver file of the latest version of the subscriber device of the DSL network and transmitting the latest driver file to the subscriber device at the request of the subscriber device; When accessing the DSL network, the upgrade server checks the driver version and, in the case of a newer version than the currently installed driver, the subscriber device of the DSL network downloads and installs the latest driver file.

In addition, the subscriber device accesses the upgrade server through the web so that the subscriber can check, download and install the update file to upgrade remotely.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description and the annexed drawings, detailed descriptions of well-known functions and configurations that may unnecessarily obscure the subject matter of the present invention will be omitted. In addition, an example of DSL will be described using an example applied to an ADSL network.

2 is a block diagram of an upgrade service system according to an embodiment of the present invention. In the ADSL network of FIG. 1 as described above, a subscriber (DB) 124 having a database (DB) 124 of upgrade driver files in the Internet 120 is provided. The upgrade server 122 of the ADSL service provider for providing the upgrade service to the user is connected, and the manager 126 for managing the update of the driver of the upgrade server 122 is connected through the Internet 120. Herein, the same reference numerals are given to the components corresponding to those of FIG. 1, and parts not directly required for description of the present invention are omitted for convenience.

The upgrade service of the upgrade service system includes a data parsing module, a driver comparison and processing module when connected, a file transfer and decompression module, a driver file automatic installation module, a driver database manager module, and an upgrade server 122. ) And the client system of the subscriber device 100. The server system executes an administrator management service and an upgrade service through a web server and a database server as shown in FIG. 3, and the client system transmits message communication, a database connection, and a driver stream with the server system as shown in FIG. 4. It is designed to handle the service.

The upgrade service of the present invention as described above is divided into two types: an automatic upgrade service that is automatically upgraded when a subscriber accesses an ADSL network, and a web upgrade service that can be managed and downloaded on the web.

First, the automatic upgrade service automatically compares the driver version of the subscriber device 100 when the subscriber is connected, upgrades to the latest version of the driver, and always receives the new version of the driver and the GUI (Graphical User Interface). This is performed by driving an application for displaying a screen as shown in FIGS. 7A to 7C and includes a version comparison module, a driver download module, and a driver installation module. The version comparison module compares the subscriber device driver version with the latest device driver version and determines whether to download the software. The latest device driver version query module, which receives the latest device driver version from the upgrade server 122, Compared to the subscriber device 100 driver, the upgrade server 122 has a driver version comparison module that downloads when the driver version is high and stops when the driver version is high. The driver download module downloads the driver using HTTP (Hypertext TransferProtocol). The driver download module receives the driver file in the form of a binary stream using HTTP, and parses the binary stream. Has an installation binary parsing module that stores driver files. The driver installation module drives the downloaded installation file. The driver installation module includes an installation file driving module for driving the original driver file to execute the installation program, and a service reconnection module for reconnecting the service after the installation is completed.

Referring to FIGS. 5 and 6, which show flowcharts of processing of the automatic upgrade service of the subscriber device 100 and the upgrade server 122 according to the above-described automatic upgrade service, respectively, the subscriber device 100 of FIG. When the ADSL connection is performed in step), in step 202, the user accesses the upgrade server 122 while displaying a screen window as shown in FIG. 7A, and requests a driver version check in step 204. When the driver version check request is received from the subscriber device 100 as described above, the upgrade server 122 responds to the response of the latest driver version of the database 124 and the corresponding subscriber device (step 302) in step 300 of FIG. Comparing the driver versions of step 100), the comparison result is notified, and in step 304, the download request is checked. If the download request is received in step 306, the latest version of the driver file is transmitted to the subscriber device 100, and if the download request is not received, it ends. In this case, the subscriber device 100 checks whether the upgrade is necessary based on a comparison result between the latest driver version received from the upgrade server 122 and the driver version of the corresponding subscriber device 100 in step 206. If the driver version of the subscriber device 100 is the same as the latest driver version, the process ends. If the driver version of the subscriber device 100 is the same as the latest driver version, the subscriber station 100 displays the screen window as shown in FIG. At this time, if the user selects the installation progress, in step 210, the user requests a download request to the upgrade server 122, downloads the latest version of the file, installs it in step 212, and then displays a screen window as shown in FIG. 7C. Exit if you do not want to install.

Therefore, if the current version of the driver file, such as the version of the connection to the upgrade server 122 to check remotely, if there is any information about the upgrade, including the update automatically performs a live (live) upgrade does not inconvenience the subscriber and error This can minimize subscriber complaints and improve the quality of services.

On the other hand, remote web upgrade service is a service that allows users to access the ADSL network service provider's customer service information web system at any time and check the update contents and download the update file. It shows the list of updates and downloads the update file. An update list service for installing and an update management service for the administrator 126 to manage uploading / inputting / modifying / deleting drivers.

Referring to FIG. 8, which shows a flow chart of an upgrade web service of a subscriber device 100 according to an embodiment of the present invention according to the web upgrade service as described above, the subscriber device 100 includes an upgrade server at step 400. 122, accesses a web service through the Internet 120, retrieves the update list in step 402 by the application as shown in FIG. 9, downloads the update file in step 404, and then upgrades the server in step 406. 122) and the connection is terminated.

Therefore, subscribers can access and download the update list for applications such as driver upgrade as well as speed improvement at any time by accessing the web.

Meanwhile, the effects of improving scalability, economy, reliability, and convenience according to the announcement server 122 for web services are as follows. First of all, scalability is easy to expand the server capacity and the number of concurrent users, easy to expand the number of concurrent users, easy maintenance and further development and expansion. In particular, it is much easier to change the design, develop and expand the web service further by the operation of the web service. Therefore, the cost, duration, and development difficulty are much lower than the development of the application. In addition, it is possible to interoperate with the EMS 116 and other computer infrastructure management software. It can be linked with ANSWERS to provide data for statistical analysis such as failures, and more extended service is possible in connection with facility management and maintenance. It can be integrated with TIMS to enable automation by extending the processing of telephone service requests to the web. It can be integrated with ICIS and can be extended with customer information service and database. In addition, Web server development is faster than FTP, and can be applied to all Internet-enabled devices in the future.

Looking at the economic feasibility, since it is managed by a central server, the cost of server installation, management, and maintenance can be reduced compared to regional servers. In addition, the cost of expanding the number of concurrent users is reduced. FTP varies depending on the server, but most of them limit the connection to a maximum of 256, but the WEB method can theoretically allow unlimited connections starting from a minimum of 100,000 connections per unit. In addition, all management of the database, etc. is integrated.

In the following, reliability and convenience are integrated and managed only in one web server, so operation is simple and it is easy to cope with a failure. In the event of a failure, processing links two or more servers to each other, and even if one fails, the other takes over and fails to act as a backup system. In terms of reliability, data defects can be minimized by sharing important information such as databases, and when one server node stops working, another server node takes the operation with little interruption to the user and improves service stability. . In maintenance, there is little server downtime for maintenance and service reorganization. In other words, one server maintains the service as it is, and the maintenance work is performed as the other, and the service is performed as soon as it is completed. In addition, the load in the server group is balanced, thereby minimizing the load on the server, and reducing the load on the packet by dividing the packet into smaller pieces than the FTP server. In operation, it is operated in the form of web, so administrators can manage the entire announcements and updates regardless of time and place, multiple administrators can manage them at the same time, and can distribute tasks by dividing authority by administrator. In addition, the interface of the web service can be easily changed by simply uploading a picture, so the interface is flexible. In the case of the FTP server, the resume function is limited, and the web server can provide the resume function, so that the resume function can be used in an extended service in the future.

Meanwhile, in the above description of the present invention, specific embodiments have been described, but various modifications can be made without departing from the scope of the present invention. In particular, the embodiment of the present invention has been applied to the ADSL network, but the same applies to other types of DSL network. In addition, although the example of the automatic upgrade service and the web service as the form of the announcement automatic guide service, only one type of service may be used. Therefore, the scope of the invention should not be defined by the described embodiments, but should be defined by the equivalent of claims and claims.

As described above, the present invention does not inconvenience the subscriber by minimizing the subscriber's dissatisfaction and improves the quality of service by automatically checking the version of the current subscriber's driver file and executing the upgrade when the subscriber accesses the DSL. There is an advantage. In addition, subscribers can access and download the update list for applications such as driver upgrade as well as speed update anytime by accessing the web.
