DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a client-server system in which a client accesses a server by designating a locator and acquires contents held by the server as needed.

[0002]

2. Description of the Related Art For example, on the Internet, a user using a personal computer, a portable telephone device (client), or the like starts a WWW (World Wide Web) browser, and, for example, a company, an organization, an individual, etc. Access the established homepage (site) and access information (contents) such as images, text, or audio
Downloading has been done.

In this case, the server side CGI (Common Gate)
The way interface) requests specific information from the client when the client attempts to download the data of the specific content, and downloads the specific content only when the information is appropriate. Some are allowed. For example, when the content is paid information, client-side ID information (for example, a user name or a telephone number registered by a user with a provider) is required to charge the user according to the provision of the information. You.

FIG. 6 shows a schematic example of a sequence in this case, which is a TCP / IP (Transmission Control).
l Protocol / Internet Protocol). First, the browser on the client side displays one screen of a homepage by a user operation: page (A).
URL for downloading content data
When (http://www.AAA.com) is specified, a request for the page (A) is transmitted to the server side (). Then, the CGI on the server side determines the U requested by the client.
Download the content of the RL page (A) to the client side ().

In this case, it is assumed that URL information for accessing the page (B) is presented in the image data which is the content of the page (A) (that is, the URL is displayed on the screen as character information). There). Then, it is assumed that the user performs an operation of specifying URL: (http://www.BBB.com) to access the page (B) based on the URL information. Then, the browser transmits the URL to the server side ().

[0006] Upon receiving the page (B) access request, the server announces to the client that, for example, the user ID information is required as specific information in order to access the page (B), and inputs the input. Request (). Then, the user inputs the ID information (for example, ID
-ipd123) and send it to the server (). Then, when the server authenticates the ID information, the server causes the client to download page (B) ().

When the content data of the page (B) is downloaded to the client, the browser displays the data on a display. Then, the user of the client can browse the image data of the page (B) on the display.

[0008]

That is, in the above procedure, the client side needs two round trip procedures of-and-in order to download the page (B).
Then, the user has to input the specific information requested by the server one by one, and there is a problem that the operation is troublesome.

[0009] The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a client-server system in which a client can easily access contents requiring specific information.

[0010]

According to the client server system of the first aspect, the server has a locator of a specific content corresponding to specific information on the client side necessary for permitting access to the content. And provides the client with access information. Then, when a keyword is added to the access information of the content to be requested, the client adds specific information corresponding to the keyword to the locator of the content and makes a request to the server. When the specific information corresponding to the keyword is added to the specified locator, the server permits the client to acquire the corresponding content.

That is, conventionally, when a client makes an access to acquire a specific content on a server, it is known that the access first requires presentation of specific information, and thereafter, the user is requested to do so. Operation to input specific information. On the other hand, according to the first aspect of the present invention, it is possible to know that specific information is necessary at the time of the first access to the content and the type of the specific information by a keyword indicated from the server side.

When the user performs an operation for requesting the content, the specific information corresponding to the keyword is automatically added to the locator to make a request to the server, and the server adds the specific information to the locator. If so, the acquisition of the corresponding content is permitted. Therefore, the procedure for the client side to exchange with the server side to acquire the specific content can be reduced as compared with the related art. In addition, since the user does not need to input the specific information by himself / herself, the convenience can be generally improved.

According to the client server system of the second aspect, the server changes the content of the content permitted to be acquired in accordance with the content of the specific information, so that the server automatically changes the information provided to the client side. Can be diversified.

According to the third aspect of the present invention, since the specific information is the ID information on the client side, for example, the serial number of the terminal device constituting the client and the user who uses the client are assigned by the provider. The user name or a user name registered in advance to access a specific content can be transmitted to the server side. Then, the server can provide the content individually for each client or user by obtaining such ID information that specifies the client or user.

According to the client-server system of the fourth aspect, the specific information is various information accompanying the client-side ID information. The information accompanying the ID information includes, for example, information on the time when the client performed communication to access the server, information on the communication line usage fee charged according to the communication time, and the like. Therefore, the server can provide different contents according to such various kinds of information. According to the client server system of the fifth aspect, the client is prohibited from changing the specific information by the user. That is, if the information such as the communication time and the usage fee can be changed by the user, there is a possibility that handling between users or between clients (for example, a method of presenting content) becomes unfair.

According to the present invention, the client can automatically add the specific information to the locator and transmit it to the server according to the keyword presented by the server without the intervention of the user. is there. Therefore, it is possible to prohibit the user from changing the specific information and prevent the information from being falsified, and to make the handling between users or clients fair.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS. FIG. 5 shows a schematic configuration of the client server system 1. The mobile phone device (client) 2 is provided with operation keys, a microphone for transmission, a speaker for reception, an LCD, and the like on a front portion of a housing thereof, and a telescopic type on an upper surface portion of the housing. Rod antennas are arranged.

Although not specifically shown, the electrical configuration inside the portable telephone device 2 is mainly composed of a control circuit such as a microcomputer. The audio signal input to the microphone is A / D-converted and, for example, π
/ 4 shift DQPSK (Differential Quadrature Phase)
Shift Keying) signal.
The signal is orthogonally modulated by a carrier signal in the Hz band, and is transmitted to the outside as a radio signal from an antenna.
On the other hand, when the antenna receives a radio signal, the received signal is demodulated, D / A converted, and output as an audio signal from the speaker.

The portable telephone device 2 is configured to be able to perform data communication in addition to a telephone call by transmitting and receiving voice data, and to perform data communication in the client server system 1. The browser 3 is incorporated (installed) inside the mobile phone device 2.
Application software for accessing a homepage provided on a WWW server and downloading data of necessary contents, and is executed by a control circuit.

The mobile telephone device 2 accesses the management center 5 via the base station 4. A server 7 is connected to the management center 5 via the Internet 6, and various sites are provided on the server 7. Also,
The CGI 8 is incorporated in the server 7 and is interface software for controlling access to the server 7 when a client such as the mobile phone 2 accesses the server 7.

The control circuit of the portable telephone device 2 internally stores user ID information (for example, "ID-ipd123"). In addition, the line connection time, the line usage fee (for example, on a monthly basis), etc. are automatically calculated internally each time a call or the like is made, or the system is accessed as necessary, The data managed and managed by the system is downloaded and stored. For example, the line connection time is "6H
(6 hours) ”and the line usage fee is“ 3200Y (3200Y
The information such as the line connection time and the line usage fee is various information accompanying the ID information.

The control of these data is automatically performed by a control circuit in the mobile phone 2, so that the user can display the data on the LCD and refer to it. It is impossible to edit and rewrite the numerical values.

Next, the operation of the present embodiment will be described with reference to FIGS. FIG. 1 is a diagram corresponding to FIG.
This shows a sequence in the case where content data on the server 7 is downloaded between the mobile phone device 2 as a client and the server 7. FIG.
FIG. 3 is a flowchart showing the contents of control by the browser 3 on the mobile phone device 2 side, and FIG.
6 is a flowchart showing control contents according to the first embodiment.

In FIG. 2, when a URL (locator) is designated by a user's operation (step A1, "YES"), the browser 3 of the portable telephone device 2 adds a keyword described later to the designated URL. It is determined whether or not there is (Step A2). If the keyword is not added ("NO"), the designated URL is transmitted as it is (step A4), and the process waits until page download is started (step A5).

Here, reference is made to FIG. The procedure in FIG. 1 is the same as the procedure in FIG. 6, in which the user specifies a URL (http://www.AAA.com) for downloading the data of the content of the homepage: page (A). In step A4, the browser sets the URL (htt
p: //www.AAA.com) to the server 7 side.

On the other hand, in FIG. 3, the CGI on the server 7 side
8 waits for a page request (URL reception) from the client side (step B1), and if there is a page request ("YES"), the page is downloaded (step B2). In this case, C on the server 7 side
The GI 8 downloads the content data of the page (A) of the URL requested by the mobile phone device 2 to the mobile phone device 2 side (of FIG. 1).

At this time, when the data downloaded to the client side is displayed as an image on, for example, the LCD of the portable telephone device 2, the CGI 8 displays a page for which the client side needs to present specific information in order to access the data. The corresponding keyword is added to the end of the URL, and the display is performed.

Here, reference is made to FIG. FIG. 4 is a correspondence table between keywords and specific information that can be referred to by the browser 3 of the mobile phone device 2 and the CGI 8 of the server 7 respectively. That is, the specific information corresponding to the keyword “xxx” is the ID information of the user, the specific information corresponding to the keyword “abc” is the line connection time of the user, and the keyword “de”.
The specific information corresponding to f "is the line usage fee of the user,....

That is, for example, if a user's line connection time is required as specific information to access the page (B), the CGI 8 transmits the URL of the page (B): (http: // ww
w.BBB.com) with the keyword “abc” added to the end of the display so as to be displayed as follows on the mobile phone device 2 side. http://www.BBB.com?abc and C
The GI 8 waits until there is a request for a further page from the client side (step B3).

Referring to FIG. 2 again, when download of page (A) is started by server 7, browser 3 also determines "YES" in step A5 and performs download processing (step A6). Then page (A)
Is taken into the portable telephone device 2, the image data is displayed on the LCD screen, and the URL is displayed. Then, the process proceeds to step A1.

Next, when the user wants to access the page (B) from the image of the page (A) by referring to the image of the page (A), for example, the cursor on the LCD is moved to URL: (h
It is assumed that the URL of the page (B) is specified by moving to ttp: //www.BBB.com? abc). Then, in steps A1 and A2, the browser 3 determines that “YE
S ”, and the keyword“ a ”is entered in the URL of page (B).
bc ”, that is, the line connection time“ 6 ”
H ”is added and transmitted to the server 7 side (step A3,
1). For example, http://www.BB
B.com/6H

When the CGI 8 of the server 7 receives the page (B) access request (step B3,
"YES"), it is determined whether or not the specific information is added to the URL (step B4). If not, the corresponding page is downloaded as usual ("NO") (step B6). In this case, since the line connection time “6H” is added to the URL of the page (B), the CGI 8 determines “YES” and authenticates the added specific information (step B5).

That is, the specific information requested by the server 7 is the line connection time, and it is determined whether the specific information requested by the client is correctly transmitted. In this case, the authentication is determined to be OK based on the identifier “H” indicating the line connection time. Then, the CGI 8 downloads the data of the page (B) corresponding to the line connection time “6H” to the client side (step B7).

Here, in the client server system 1, an example of a service provided by the contents of the server 7 when the client is the mobile phone device 2 will be considered more specifically. For example, the mobile phone device 2
Is a product of Company D, and the user accesses the homepage created by Company D using the mobile phone device 2.

At this time, when downloading and browsing the image data of a part of the pages, the server 7 requests the line connection time as specific information from the portable telephone device 2 as described above. Then, when the line connection time is transmitted, it becomes possible to cause the mobile phone device 2 to download different contents (image data) according to the line connection time.

That is, when the user of the portable telephone device 2 repeatedly accesses the same page of Company D, for example, different image data can be obtained each time the cumulative value of the line connection time increases. The entertainment provided to the user can be improved, or the interest of the user can be increased. Then, it is conceivable that the user may be motivated to use the cellular phone device 2 more and increase the accumulated value of the line connection time.

As described above, according to the present embodiment, the server 7
Adds a keyword corresponding to client-side specific information necessary for accessing the page to the URL of a specific page and provides the client side with access information. If a keyword is added to the access information, a request is made by adding specific information corresponding to the keyword to the URL. Then, when specific information corresponding to the keyword is added to the URL, the server 7 allows the mobile phone device 2 to acquire the page specified by the URL.

That is, at the time of the first access to a specific page on the server, the portable telephone device 2 knows that the specific information is necessary and knows the type of the specific information by a keyword indicated from the server 7 side. it can.

When the user performs an operation for requesting the page, the portable telephone device 2 automatically adds specific information corresponding to the keyword to the URL and transmits the URL to the server 7, and the server 7 If the specific information is added, the acquisition of the corresponding page is permitted. Accordingly, the procedure for the client to exchange with the server 7 can be reduced as compared with the related art. In addition, since the user does not need to input the specific information by himself / herself, the convenience can be generally improved.

Further, the server 7 changes the content of the page to be downloaded to the mobile phone device 2 according to the data value of the line connection time by using the specific information as the line connection time in the mobile phone device 2. The information provided to the user can be automatically changed and diversified.

In the portable telephone device 2, change of the line connection time data by the user is prohibited. That is, according to the present embodiment, the mobile phone device 2 automatically adds specific information to a URL according to a keyword presented by the server 7 without user intervention and transmits the URL to the server 7 side. Is possible. Therefore, by preventing the user from changing the specific information and preventing the information from being tampered with, it is possible to make the handling between users or clients (how to provide content such as pages) fair.

The present invention is not limited to the embodiment described above and shown in the drawings, and the following modifications or extensions are possible. For example, the specific information may be client-side ID information. The ID information referred to here is, for example, a serial number of a terminal device constituting the client, a user name given by a provider to a user using the client, or a user name registered in advance to access a specific page. And so on. The server then identifies the client or user with an I
By obtaining the D information, a page can be individually provided for each client or user. The form of providing the content to the client side in connection with the acquisition of the specific information on the server side is not limited to the above embodiment, and various modifications are possible. For example, URL on the server side
By adding two or more keywords in succession, two or more pieces of specific information may be transmitted from the client side at the same time. For example, it is described as follows. ht
The tp: //www.BBB.com? xxx? abc content is not limited to image data and character data, but may be audio data or a combination thereof. The client is not limited to the mobile phone device 2, but a PHS (Perasonal Handyphone System)
It may be a wireless communication device capable of only data communication without a communication function or a communication function, or a personal computer performing communication via a modem or TA (Terminal Adoptor).
