Description

Wireless based thin client service system and method for transmission data reduction

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wireless based thin client service system through transmission reduction, and a method and a computer readable recording medium recording a program for realizing the method. More specifically, the thin client is not used in a wireless communication network. By applying technology to the wireless network, the transmission volume of the wireless network is drastically reduced, thereby quickly providing users with services such as Internet Service Providers (ISPs), application service providers (ASPs), content provision, and entertainment. The present invention relates to a wireless-based thin client service system and a method thereof, and a computer-readable recording medium having recorded thereon a program for realizing the method.

In general, a terminal in a computer is a device installed on the user's side, and usually includes a keyboard and a monitor, and a device which itself relies on processing power on another computer such as a mainframe or a server with little software.

Meanwhile, in data communication, a terminal is a device connected to either end of a signal transmitting or receiving end, and is actually a device connected to extended endpoints of a network except for network devices in the middle or middle.

1A-1C are exemplary diagrams of techniques of a conventional client / server environment.

In the prior art, as shown in FIG. 1A, a client / server environment in which a plurality of clients 12 are connected to one server 11 through a network to perform a task while exchanging data and control information with each other is provided. have.

However, in the system shown in FIG. 1A, the client 12 has a hardware device such as a central processing unit, a floppy disk driver, a hard disk driver, and the like, and a plurality of application application software, such as a personal computer.

However, when the system is configured as described above due to the rapid development of personal computers, the cost burden is increased due to the improvement of hardware specifications, and the burden on the client is increased due to the diversification of software. In addition, with the burden of installing and maintaining clients, management costs have grown exponentially with the number of clients.

In order to solve this problem, a network computer concept as shown in FIG. 1B and a thin client terminal concept as shown in FIG. 1C are considered.

First, the network computer 14 has a very small storage capacity and cannot store applications and files on its own because there is no large storage device such as a disk driver. Therefore, the network computer 14 is designed to be connected to the server 13 via a network, download necessary software, and execute the network computer itself.

In this way, if the application software is installed only on the server 13 side when the network computer 14 is used, and only the server side software is updated when the software update is required, the same effect as updating the software of all network computers using the same is obtained. As a result, maintenance costs can be greatly reduced.

In addition, it is not necessary to update the hardware according to the software update, and there is little separate peripheral hardware, so it is possible to minimize the occurrence of the failure, and in the event of a software failure, only the server needs to be healed so that it can respond quickly to the failure. It can also reduce costs.

In addition, it can centrally control all users' clients and reduce the risk of virus infection.

On the other hand, the thin client terminal 16 also has only basic hardware and software like the network computer 14, and most applications and the like are stored in the server 15. However, unlike the network computer 14 downloading the software from the server 13 and executing the software, the thin client terminal 16 is the server 15 only when the application or file is executed in the server 15, the result is the server 15 The difference is that it is simply displayed from the network.

Therefore, in the case of using the thin client terminal 16, in addition to the above-described advantages, there is a further advantage that the service can be performed with less bandwidth than using the network computer 14.

Despite these advantages, such thin client terminal / server technologies are currently used only in wired environments and are not used in current wireless environments (IS95-A, IS95-B).

2 is an exemplary view of a conventional wireless Internet environment.

As shown in FIG. 2, in the conventional wireless Internet environment, a WAP (Wireless Application Protocol) browser mounted on a wireless terminal 21 such as a personal digital assistant (PDA), a mobile communication terminal, or the like is connected to a base station 22 and a wireless communication network ( 23, the WAP gateway 24 requests necessary information (document, video, image, etc.).

Then, a WAP gateway 24 called a WAP proxy converts a wireless application protocol (WAP) into a transmission control protocol / Internet protocol (TCP / IP) and then a corresponding information provider (IP) 26 through the Internet 25. Hyper Text Transfer Protocol (HTTP) form information is taken from the data, and the entire data is converted into HTML (Hyper Text Markup Language) or WML (Wireless Markup Language) form and compressed to wirelessly through the wireless communication network 23 and the base station 22. The application protocol (WAP) is transmitted to the wireless terminal 21.

Then, the WAP browser of the wireless terminal 21 interprets the received information and displays it to the user.

As described above, in the conventional wireless Internet environment as described above, the WAP gateway 24 compresses all the data (30 KBytes per screen) in the form of HTTP received from the information provider 26 to about 1/3 to compress the wireless communication network 23. It is delivered through. Therefore, even if the WAP gateway 24 compresses and transmits the information, the transmission data amount (10KByte) is still large compared to the transmission speed of the wireless communication network (in theory, IS95-A: 9.6Kbps and IS95-B: 64Kbps).

As a result, the transmission speed of the actual wireless communication network is much lower than the theoretical speed, and thus, the transmission time (10 seconds or more) takes a lot, and the user has to wait for the result tediously and the communication cost is excessive. However, there is a problem in that a network operator takes a lot of load on the network.

In the present invention, in order to solve the above problems, a thin client technology, which has not been used in a wireless communication network, is introduced into a wireless network environment, thereby providing Internet service providers (ISPs) and application service providers (ASPs). ), Content provision and entertainment.

The present invention has been proposed to solve the above problems, by applying a thin client technology that is not used in a wireless communication network to the wireless communication network by dramatically reducing the amount of transmission of the wireless communication network, improving the transmission speed of the wireless communication network to the user quickly To provide a wireless-based thin client service system that can display information, reduce costs, and reduce network load to a service provider, and a computer-readable recording medium recording the method therefor and a program for realizing the method. The purpose is.

3 is a configuration diagram of an embodiment of a wireless-based thin client service system according to the present invention.

As shown in FIG. 3, the client operating system 30 of the client device transmits a user's command such as a pen input or a key input or a touch screen input to the wireless communication unit 31 and displays display information from the wireless communication unit 31. Screen update information) is received and displayed to the user. Here, the client operating system 30 may be used, such as Microsoft Windows CE.

In addition, the wireless communication unit 31 of the client device performs a wireless communication with the base station 32 of the wireless network, that is, converts a user command from the client operating system 30 into a wireless transmission format and transmits the network through the base station 32. It transmits to the side and converts the display information received from the network side through the base station 32 and delivers to the client operating system (30). Here, the wireless communication unit 31 may use a mobile communication terminal, a personal mobile communication terminal, a wireless data terminal, a common frequency communication terminal.

The base station 32 and the wireless communication network 33 use the base station of the communication operator and the wireless communication network as they are, and transmit user commands from the client side to the terminal server 34, and display information from the terminal server 34. It performs the function of delivering to the client side.

In addition, the terminal server 34 analyzes the user command received through the wireless communication network 33, extracts the screen update information (display information) necessary for displaying the result information after the terminal server itself performs the corresponding function, and the client The screen update information is converted to fit the screen size (eg, 1024x768, 800x600, etc.) on the side, and then compressed and transmitted to the client device through the wireless communication network 33 and the base station 32.

At this time, if the result of interpreting the user command is a request for Internet access and necessary information (documents, videos, advertisements, images, contents, entertainment, securities, etc.), the terminal server 34 provides a corresponding information provider (through the Internet 35). 36) and then extracts the screen update information (display information) necessary to display the resulting information from the HTTP form, converts the screen update information according to the screen size of the client, and then compresses it to perform the wireless communication network 33 and It passes to the client device side through the base station 32. In this case, in order to use the existing caching function for Internet search, a caching server may be further provided, or the caching function may be mounted in the terminal server 34. As such, the present invention can be efficiently applied to a service such as an Internet service provider (ISP).

If the result of interpreting the user command is a request for an application service provider (ASP), content, or entertainment provided by the user, the terminal server 34 corresponds to the corresponding ASP server 37, content server 38, and entertainment. After accessing the server 39 or the like to execute the corresponding application, to search for contents, or to perform entertainment and receive the result information, the screen update information (display information) necessary for displaying the result information is extracted and the client is extracted. The screen update information is converted to fit the screen size (eg, 1024x768, 800x600, etc.) on the side, and then compressed and transmitted to the client device through the wireless communication network 33 and the base station 32. As such, the present invention can be efficiently applied to services such as application service providers (ASPs), content provision, and entertainment provision.

In the process of extracting the screen update information (display information) required to display the result information, the information that is not helpful to the user and increases the amount of data to be transmitted (for example, a banner advertisement that constantly changes constantly) is transmitted in advance. The amount of data can be further reduced. As a conventional method of reducing the amount of transmission data, there is a method of deleting image data, link information, and information for decoration, but such a conventional method may delete information that plays an important role for a user to grasp information contents. There is a disadvantage. Therefore, in the present invention, since the amount of transmission data can be drastically reduced by applying the thin client technology, only very unnecessary information is selectively deleted in this process.

In the present invention, in order to perform the various functions as described above, without having the ASP server 37, the content server 38, the entertainment server 39, each of the multiple terminal server 34 to perform each function. Alternatively, one or two terminal servers 34 may be provided, and functional servers such as the ASP server 37, the content server 38, and the entertainment server 39 may be provided for each purpose. In this case, the terminal server 34 may be a Windows terminal server, which is a kind of Microsoft Windows-based terminal (WBT), and may be used by mounting Microsoft's Windows 2000 and Citrix Systems' metaframe. have.

In particular, when the billing method of the telecommunication service provider is switched from the billing method according to the communication time to the billing method based on the packet transmission amount, the user fee can be drastically reduced compared to other service methods. You can take it and share it with your users. To this end, a function of changing the charges according to the operator's request is implemented in the algorithm of the billing system of the telecommunications operator, and a billing management must be performed by providing a separate provider billing server (not shown) to be linked to the billing system. . That is, when the billing server of the operator notifies the billing system of the telecommunications provider of the amount to be actually billed to the user and the amount to be returned to the provider according to the termination of the user's access, the billing system of the telecommunications carrier may accept the billing system.

As described above, in the present invention, unlike the prior art of transmitting all the data, by transmitting only display information, the amount of data transmission and its transmission time (from about 10 seconds or more to about 1 to 2 seconds) can be drastically reduced. It can reduce the load on the network, display the results directly to the user, reduce the communication charges caused by the long waiting period, and greatly reduce the usage fee when charging based on packet volume. have.

In the above example, the present invention is applied to a mobile communication network, a personal mobile communication network, a frequency public communication network, etc., but the present invention may be applied to the same concept in a wireless LAN environment. In this case, the wireless client device accesses the Internet using a personal computer or server connected to an intranet or the like as a terminal server through a wireless LAN network. Alternatively, the wireless client device accesses the Internet using a personal computer or server connected to a wireless LAN network as a terminal server.

4 is a flowchart illustrating an embodiment of a wireless-based thin client service method in a client device according to the present invention.

First, when the wireless client device is turned on, the wireless client device requests a wireless-based thin client service connection to the terminal server through the wireless network according to a user input (41). In operation 42, the wireless client device requests authentication to the terminal server through the wireless network. Thereafter, the wireless client device receives basic display information (initial screen information) from the terminal server through the wireless network and displays the same to the user (43). The wireless-based thin client service initialization process may be performed collectively by one-click of a user.

Thereafter, the client device transmits a user command event (internet connection and necessary information request, specific service request provided by the terminal server, etc.) input from the user in the form of a pen or key or a touch screen to the terminal server through the wireless network. (44).

Subsequently, display information (screen update information) necessary for displaying the result of the user command executed on the terminal server is converted to fit the screen size of the client device, and the client device receives the compressed information from the terminal server through the wireless network (45). ). In this case, after extracting the display information necessary to display the result, the terminal server may further reduce the amount of transmitted data by further selecting and deleting display information which is not helpful to the user and increases the amount of transmitted data. (Not shown in the figure).

Thereafter, the client device decompresses the received display information (46) and updates the screen according to the display information (47). Thereafter, the process repeats the process 44 of transmitting the user command event input from the user to the terminal server through the wireless network.

Meanwhile, when the connection termination interrupt is input from the user during each process, the terminal terminates the connection termination event to the terminal server through the wireless network (not shown).

5 is a flowchart illustrating an embodiment of a wireless-based thin client service method in a terminal server according to the present invention.

First, the terminal server receives a wireless-based thin client service connection request from a client device through a wireless network and approves the connection (51). The terminal server authenticates by receiving an authentication request from the client device through the wireless network (52). Thereafter, the terminal server transmits basic display information (initial screen information) to the client device through the wireless network to be displayed to the user (53). The wireless-based thin client service initialization process may be performed collectively according to the user's one-click request.

Thereafter, the terminal server receives a user command event (internet connection, required information request, specific service request provided by the terminal server, etc.) input from the user in the form of a pen, key, or touch screen from the client device through the wireless network. Interpret the user command (54).

Subsequently, after the terminal server interprets the user command and performs the corresponding function, the terminal server extracts display information (refresh information) necessary to display the result information (55) and displays the display information according to the screen size of the client. After transforming (56), the display information is compressed and transmitted to the client device through the wireless network to be displayed (57).

In more detail, if the result of interpreting the user command is an internet connection and a request for necessary information (documents, videos, advertisements, images, contents, entertainment, securities, etc.), the terminal server may form an HTTP form from a corresponding information provider through the Internet. After the information is obtained, the display information necessary to display the information is extracted, the display information is converted to fit the screen size of the client side, and then compressed and transmitted to the client device side through the wireless network.

If the result of interpreting the user command is a request for an application service provider (ASP), content, or entertainment provided by the user, the terminal server accesses the corresponding ASP server, content server, entertainment server, etc., and executes the corresponding application. After receiving the result information after receiving the result information or performing entertainment, extracting the display information necessary to display the result information, converting the display information according to the screen size of the client side, and then compressing the wireless network. It passes to the client device side through.

On the other hand, after the terminal server extracts the display information 55 necessary to display the result information 55, it further performs a process of preselecting and deleting the display information which does not help the user and increases the amount of transmission data. The transmission data amount can be further reduced (not shown).

On the other hand, when the billing method of the telecommunications carrier is switched from the billing according to the communication time to the billing method based on the packet transmission amount, the user fee can be drastically reduced compared to other service methods, so that the fee as much as this saving is saved You can take it and share it with your users. To this end, the terminal server further performs a process of notifying the carrier's billing system of the amount to be actually billed to the user and the amount to be returned to the service provider after performing the data transmission process 57 or upon termination of the user's connection (Fig. Not shown). On the other hand, this billing management function may be implemented by having a separate billing server.

On the other hand, the terminal server terminates when the connection termination message is received from the client device while performing each of the above processes (not shown).

As described above, the method of the present invention may be implemented as a program and stored in a recording medium (CD-ROM, RAM, ROM, floppy disk, hard disk, magneto-optical disk, etc.) in a computer-readable form.

The present invention described above is not limited to the above-described embodiments and the accompanying drawings, and various substitutions, modifications, and changes are possible in the art without departing from the technical spirit of the present invention. It will be apparent to those of ordinary knowledge.

The present invention as described above, unlike the prior art that transmits all the data, by transmitting only the display information has the effect that can dramatically reduce the amount of data transmission and its transmission time (from about 10 seconds to 1 to 2 seconds) significantly have.

Accordingly, the present invention can reduce the load on the wireless network and have the effect of immediately displaying the results to the user.

In addition, the present invention can not only reduce the communication fee of the user due to the long time waiting, but also can greatly reduce the use fee when charging based on the packet amount.

As described above, the present invention can significantly reduce the user fee compared to other service methods when the charging method of the service provider is changed from the charging method according to the communication time to the charging method based on the packet transmission amount, thereby reducing the user fee. You can take advantage of these benefits, or you can realize various services such as sharing the benefits with users.
