Description

Methods, recording medium, server and client system for upgrading software

The present invention relates to a method, a record carrier, a server and a client system for upgrading software in a client system.

Software installed within client systems, such as computers, is constantly being developed with new versions, and unless a user of such software continues to upgrade the version of the software he or she has, other people may not Problems such as not being able to see or participating in network games played using higher versions of software may occur.

Therefore, the user using the software needs to continuously upgrade his or her own software in order to connect or compatible with other users' systems. In order to upgrade the conventional software, the user upgrades the software in one of the following ways. .

First, there is a method of upgrading by purchasing and installing an installation program for each product.

This is the same method as upgrading the software for the first time, and the same method is required to install the software for the first time.However, in order to upgrade the already installed software, a separate installation program is required for each upgrade. There is a problem to make.

Second, there is a way to support upgrades by embedding programs that support upgrades within each product.

Upgrades in this manner include A3's V3 (trade name) program, which includes software upgrades that are scheduled at regular scheduled times. Supported modules are built in.

However, in order to upgrade through this method, a separate module for supporting the upgrade must be made for each software, so the size of the software increases, and each server operates a server for supporting the upgrade separately. There is a problem in that it costs a lot.

Third, there is a way to upgrade the software by providing a system in the form of providing upgrade information for all its products on the Internet website.

This is the case when an update is made through Microsoft's Windows update site (http://windowsupdate.microsoft.com). Looking at the above method in detail, the first time Microsoft Windows, etc. is installed, A file containing information about the list and version of several software such as Internet Explorer and Outlook Express will be installed together. When the user accesses the Windows update site, the contents of the file and the current site will be installed. The list of upgraded software is displayed by comparing the contents stored in the server. When the user selects the software to be upgraded from the list, the installation program for the selected software is transmitted to the user's computer to upgrade the selected software.

However, in order to upgrade the software in the above-described manner, it is necessary to create and install a file that records the list of software separately, and also to upgrade the software that is not recorded in the file in the same manner as above. Even if the software is recorded in the file, if a new version different from the version recorded in the file is newly installed, the file has no problem. In addition, since the installation program must be downloaded to upgrade the selected software, there is a problem in that the size of a file to be received is increased. In addition, the above website supports the upgrade only in the Microsoft Windows-based system, there is also a problem that can not be upgraded in other operating systems (OS).

In order to solve the above problems, an object of the present invention is to provide a method for automatically upgrading various types of software installed in a client system such as a user's computer by connecting to one server.

In addition, an object of the present invention is to provide a client system for automatically upgrading the software installed therein by accessing the server.

It is also an object of the present invention to provide a software upgrade support server that supports upgrade of software in a client system to which software is automatically upgraded.

It is also an object of the present invention to provide a recording medium having recorded thereon a program for realizing a method of operating in the client system.

1 shows a schematic diagram of the overall system of the present invention.

In the present invention, a plurality of user system 110 is connected to the software upgrade support server 120 via the network 130, in which the user system is to upgrade the software in its system using the software upgrade support server This includes a user who purchases and uses software, but also includes a software manufacturer that stores his / her own software on the software upgrade support server and transmits files necessary for the upgrade every time it is upgraded.

The user system 110 may be any system that includes software such as a computer, a server, a mobile phone, and a personal digital assistant (PDA).

The upgrade support system 120 receives and stores information about software from various software manufacturers and uses the upgrade support system 120 to support upgrade of the software in the user system 110.

A user using the software may access the software upgrade support server 120 through the network 130 and upgrade the software in his or her system 110 by interacting with the server 120. The software manufacturer who manufactures the software may also access the software upgrade support server 120 through the network 130 to register their own software or register information about the upgraded version.

2 is a block diagram showing components of the user system 110 and the software upgrade support server 120 of the present invention.

The user system 110 includes a software analyzer 211, a software installer 212, and a web browser 213 as a means for the user to upgrade the software in his or her system. The software manufacturer may include one or more pieces of software 231 necessary for uploading the software of the company to the upgrade support server 120 and change the version, analysis control information 232 for the software, and installation control information 232 of the software. It includes more.

The upgrade support server 120 may include a web server 221, an upgrade software registration module 222, an analysis control information generation module 223, an installation control information generation module 224, an upgradeable software determination module 225, and a database ( 226).

Specifically, if the software analyzer 211 is set to transmit the software information in the user system 110 to the software upgrade support server, for analyzing the software in the system 110 received from the software upgrade support server. Analysis control received from the software upgrade support server when the result of analysis using the analysis control information with the information is transmitted to the server and the software information in the terminal is not set to be transmitted to the software upgrade support server. Using the information, a list of upgradeable software is generated as an HTML file and displayed to the user through the web browser 213.

The software installer 212 upgrades the software in the user system 110 by using installation control information including information necessary for upgrading the software received from the upgrade support server 120 and files necessary for upgrading the software.

The web browser 213 connects to the upgrade support server 120, transmits and receives necessary files while performing the upgrade according to the present invention, and shows the user a list of upgradeable software in the system 110 so that the user can select it. do. In addition, the installation process of the software can be shown through a web browser.

The analysis control information 232 held by the software manufacturer's system 110 for uploading to the upgrade support server 120 includes a comparison object (software version, file size, specific file of the software version 231). Some of the contents, etc.), a method of extracting a comparison target, and a procedure to be performed by the software analyzer 211, and the installation control information 232 includes a path to install files necessary for upgrading the software 211. It includes information about files to be deleted or changed in a system where an existing lower version is installed to upgrade the software, and also includes information for configuring an environment for executing the installed software when installing the software. . In addition, the installation control information is to be equipped with the control logic for the things going on in order to proceed sequentially installation installation information, screen configuration and user questions appearing on the user's screen and how the next processor to the user's response Control information is configured to control whether to deploy.

The web server 221 of the upgrade support server 120 connects with the user systems 110 through a network like the web browser 213 and transmits and receives files necessary for the upgrade process according to the present invention.

The analysis control information generation module 223 determines from the user registration information of the database 226 whether the connected user wants to upgrade only specific software, and if the user wants only specific software, If only the analysis control information on the software is selected and sent to the user system 110 through the web server, and the user does not select only specific software or the connected user is not registered in the database 226, the database Sends the analysis control information for all software of (226),

The installation control information generation module 224 configures a software version, an installation path, and software in the user system 110 analyzed by using a list which the user who has been transmitted from the user system 110 wishes to upgrade and analysis control information. By comparing the contents of the file with information about the software stored in the database 226, the installation control information is generated so that the software installer 212 of the user system 110 can upgrade the software.

The upgradeable software determination module 225 compares the analysis result of the software in the system using the analysis control information of the software analyzer 211 of the user system 110 with the information on the software stored in the database. A list of upgradeable software is generated among the software installed in the user system 110. If the user wants in advance, a list of software not currently installed in the user system 110 among software that can be installed from the upgrade support server 120 may be generated and transmitted through the web server 221.

The database 226 stores information on registered users, software and analysis control information, installation control information, and the like for each software and version, and the software, version, and / or software is accessed whenever the connected user upgrades the software. Each manufacturer counts and stores the number of times. These materials can be used by software makers to track upgrades of their software.

The upgrade software registration module 222 receives software, analysis control information, and installation control information when a software manufacturer wants to register its software or upgrades a version of already registered software. Register at

3 is a flow chart illustrating a method of upgrading software in its system 110.

There are two main ways for a user to upgrade the software in his or her system 110 using the software upgrade support server 120.

One of them is a method of allowing the user to transmit information about the software in his system 110, that is, what software is installed in his system, to the upgrade support server 120 and performing the upgrade. The other is that the user does not transmit information about the software in his system 110 to the upgrade support server 120, but only the information necessary to upgrade the software selected by the user to the upgrade support server 120 is transmitted to the upgrade support server 120. To upgrade.

The above two methods may provide only one method according to the service aspect of the upgrade support server 120, or allow the user to select one of the two methods and register it to support the upgrade through the method desired by the user. have.

3 relates to a method in which a user selects one of the above methods to upgrade.

In order to upgrade the software in the user's system 110, the user must first access the upgrade support server 120 (311). Access to the upgrade support server may be made by the user accessing the website of the server using a web browser, or may be made by running a software upgrade support program in the system 110. In addition, the connection may be made by automatically driving the software upgrade support program at predetermined intervals. The connection may be made through a wired internet network or a wireless internet network.

After the connection is established, to check whether the user has allowed or disallowed to transmit information about the software in his system 110 and whether the user has registered with the upgrade support server 120. There is a login step 312. The logging in step 312 may be omitted by setting whether to transmit the information in advance when installing the software upgrade support program and automatically transmitting the information when accessing the upgrade support server 120.

When the user logs in, it is determined whether the connected user has allowed the transmission of information and whether the user has registered with the upgrade support server 120 (313). Thus, the method of performing the upgrade is different.

First, if the user is a user who has allowed to transmit information about the software in his system 110, the software analyzer 211 in the user system 110 is the analysis control information generation module 223 of the upgrade support server 120 And receive analysis control information with information for analyzing software in system 110 (314). The analysis control information lists a comparison target (software version, file size, a part of the contents of a specific file, etc.), a method of extracting the comparison target, and a procedure to be performed by the software analyzer 211 regarding the version of the installable software. It is. The analysis control information may include information about all the software that can be supported by the upgrade support server, but if the user has set in advance that the user wants to upgrade only specific software, the analysis control information generation module of the upgrade support server 120 223 obtains only the information on the specific software from the database 226 to generate and transmit the analysis control information.

The software analyzer 211 analyzes the software in the user system 110 using the analysis control information, and as a result, that is, the type, version, and path of the software currently installed in the system 110 are installed. And so on to the server 120 (315).

The upgrade support server 120 receives the result of the analysis in the upgradeable software determination module 225 and compares the upgrade information with the information on the software stored in the database 226. It is made and transmitted to the user system 110 through the web server 221 (316). Since the software analyzer 211 analyzes the information on the software installed in the user system 110 at the time of the user access, the user upgrades the server 120 and then returns to the server 120. Even if the software is newly installed or upgraded through another path before the connection, or if new software is registered in the server 120, the server 120 may determine exactly which of the software in the user system 110 can be upgraded. It becomes possible.

In addition, since information on the software installed in the user system 110 is transmitted to the upgrade support server 120 and stored in the database 226 for each user, the upgraded version of the software is stored in the server 120. ), It can be notified to the user. The upgrade support server 120 registers a higher version of software than a version of software installed in the user system 110 stored in the database, or registers the specific software when the user desires to upgrade only the specific software. If a new version of is registered, it may further include means (not shown) to automatically notify the user.

The upgradeable software list is registered in the upgrade support server, but may include a list of software that is newly installed because it is not installed in the user system 110.

Upon receiving the list of upgradeable software, the user system 110 shows the list to the user through the web browser 213 or a software support program so that the user can select the software that he / she wants to upgrade and then upgrades the result. The server 120 transmits the data to the server 120 (317).

The installation control information generation module 224 of the upgrade support server 120 receives the list of software selected by the user and generates installation control information including information necessary for upgrading the selected software, and the upgrade support server 120 does this. A file 318 is transmitted to the user system 110 along with files necessary for upgrading the selected software stored in the database 226.

The installation control information includes a path to install files necessary for upgrading the selected software in the user system 110, a file to be erased in the user system 110 to upgrade the selected software, and the selected software. It includes information about a file to be changed in the user system 110 in order to upgrade, and includes information constituting an environment for executing the installed software when installing the software. In addition, the installation control information is to be equipped with the control logic for the things going on in order to proceed sequentially installation installation information, screen configuration and user questions appearing on the user's screen and how the next processor to the user's response Control information is configured to control whether to deploy. Thus, based on the result of analyzing the path, file configuration, file contents, etc. where the existing software is installed, without creating an installation program for the software to be upgraded, Since only the information on how to change the file configuration and file contents of the installed software is transmitted, the amount of data to be transmitted is greatly reduced, and the transmission speed is also very fast.

The upgrade support server 120 counts the number of times the user selects to upgrade for each software while transmitting the installation control information and the necessary files for upgrading, and stores them in the database 226 for each software. This will help software makers later track their software upgrades.

The user system 110 receiving the installation control information and files necessary for the upgrade from the upgrade support server 120 provides the installation progress information to the user according to the contents indicated in the installation control information using the software installer 212. The upgrade of the selected software is terminated by deleting the files constituting the software to be upgraded sequentially, changing the contents of the files, and installing the received files according to a specified path (319). Thus, since the software installer 212 is controlled by the installation control information, one software installer 212 can simultaneously install or upgrade several softwares according to the installation control information, and can only execute the installation program.

Next, if the user is set not to transmit information about the software in his system 110, that is, the user is reluctant to reveal information about the software in his system 110, The software analyzer 211 receives analysis control information including information for analyzing software in the system 110 from the analysis control information generation module 223 of the upgrade support server 120 (321). The analysis control information includes a comparison object (software version, file size, a part of a specific file, etc.) and a comparison object regarding the version of the installable software received when the user is allowed to transmit information about the software in the system. In addition to the methods and procedures that the software analyzer 211 should perform, it also includes a list of installable software and versions thereof.

As in the case where the user allows the transmission of the information, the analysis control information may include information about all the software that the upgrade support server can support, but if the user has previously set that the user wants to upgrade only for the specific software, It may also include only analysis control information for information about a particular software.

The software analyzer 211 analyzes the software in the user system 110 using the analysis control information, compares the result of the analysis with a list of software and versions that can be installed, and generates a list of upgradeable software to the user. Show (322). The upgradeable software list may be prepared as an HTML file and displayed to a user through a web browser.

If the user is selected which software to upgrade, the user system 110 transmits only the results related to the selected software among the selected software and the results of the analysis to the upgrade support server 120 (323). By doing so, the user does not transmit the information about all the software installed in the system 110, but the information can be upgraded efficiently by transmitting only the information about the software to be upgraded.

The subsequent steps are the same as when the user allowed to transmit information about the software in his system 110.

Next, if the logged in user is not a registered user in the database 226 of the upgrade support server 120, the upgrade support server 120 transmits the user to information about the software in the system 110. It is treated the same as the user set not to transmit the analysis control information is transmitted (331), the software analyzer 211 using the analysis control information to analyze the software installed in the user system 110, the upgrade made A list of possible software is shown to the user (332). At this time, the user is asked whether or not to register on the upgrade support server, and if the user wants to register, whether he / she wants to transmit information about the software in the system 110 or upgrade only the software for the specific software. If you want to set whether or not you want to proceed to the next step according to the user set, and if the user does not want to register, the upgrade process is terminated.

The above process may be performed by programming, and the program may be stored in a user-readable recording medium such as a CD-ROM, a DVD ROM, a floppy diskette, and stored in a user system.

The above process is performed when a user who installs and uses the software wants to upgrade the software in his system 110. The user system uses only the part corresponding to 210 in FIG. .

The user of the user system may be a software manufacturer, in which case the software manufacturer's system 110 includes its own software and files 231, analysis control information 232, and installation control information 233 necessary for upgrading the software. It further includes a database 230 that stores the. In addition, when the software manufacturer does not upgrade the software installed in the system 110 through the upgrade support server, the software analyzer 211 and the software installer 212 may not be provided.

4 is a flowchart illustrating a process of changing the information on the software of the company registered in the upgrade support server 120 by the software company 110, and the software company connects to the server 120. The following steps are shown after the determination as a user authorized to change the software registered in the server.

If it is determined that the connected software manufacturer can change the software registered in the database 226 of the upgrade support server 120, the server transmits a list of software that the software manufacturer can change, and the software manufacturer Selects the software to be changed from the list (401).

The upgrade support server transmits the contents of the analysis control information of the most recent version of the selected software among the software stored for each version in the database, and the software manufacturer changes and reregisters the analysis control information (402). The registered analysis control information is registered and managed in the database 226 for each version. When the analysis control information is registered, the upgrade support server 120 transmits the installation control information of the same version as the version of the analysis control information again, and the software manufacturer changes and registers it again (404). Installation control information is also registered and managed by version. When the analysis control information and the installation control information is registered in this way, the upgrade software registration module 222 of the upgrade support server 120 receives and registers each module or program for the installed software (404) and the upgrade support system 120. The version change operation of the software within is completed (405).

As described above, according to the present invention, a separate server is provided to support upgrading of the software by registering the software only on the upgrade support server without having to support the upgrade of the user who purchased the software by setting up a separate server. There is no need to operate, and users of the software can also upgrade their software by accessing only one upgrade support server without having to contact each software manufacturer to upgrade their software.

In addition, by analyzing the user's system before upgrading, it is possible to identify the list of software of the user's system that can be upgraded through the upgrade support server, and transfer only the files necessary for the upgrade based on the analysis result. This reduces the amount of data that is added and also saves time spent upgrading.
