Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information transfer system and an information transfer method for transferring content information.

[0002]

2. Description of the Related Art Recently, browsers have been installed in mobile phones,
Web access on the Internet has become possible (this type of mobile phone is hereinafter referred to as a browser phone). The browser phone is always connected to the network, providing the convenience of easily accessing the Web anytime, anywhere. Due to the spread of browser phones, content holders (CHs) such as companies and shops that provide information to Web users widely with the aim of acquiring business users can access their own websites. I am pleased to have more opportunities to receive them.

[0003]

However, due to limitations of portability, power supply, etc., the browser telephone is considered to be inferior to the personal computer (PC) in terms of display and signal processing ability in the future. Cannot finally meet the demands of the majority of content holders that they want to be fully viewed on their PCs. In addition, contents that attracted the interest of browser phone users are T
I want to select the terminal according to the PO and access the details of the information separately.

On the other hand, the personal computer is connected to the network and tends to strengthen the cooperation with the network service provided by the Internet service provider (ISP).
In particular, the establishment of a dedicated homepage (HP) called a personal homepage (PHP) for each contract user,
In the service of acting on behalf of users, an information outlet such as a bulletin board is permanently installed on the network for 24 hours as a place where authorized users can exchange information with each other. The user of the personal computer can retrieve the input information at any time by accessing this bulletin board.

The present invention has been made in view of the above problems, and an object of the present invention is to transfer information of an Internet website accessed once by a browser telephone to an arbitrary terminal such as a personal computer. To make it accessible.

[0006]

In order to solve such a problem, the present invention provides a content server, a proxy server, and a bulletin board server, each of which is arranged on the Internet and is capable of mutual communication, and is equipped with a browser. An information transfer system in which a mobile terminal and an information terminal are connected to a proxy server and a bulletin board server, respectively, and content information from the content server to the mobile terminal can be transferred to the information terminal, wherein the proxy server is a content server of the mobile terminal. When the content information stored in the register for storing the address of the content server accessed at the time of the access and the content information stored in the address of the content server in response to the access to the content server of the mobile terminal are returned, the content information Whether this content information can be transferred Control means for adding the transfer permission / prohibition information to the mobile terminal and displaying it on the display screen of the mobile terminal; and receiving the transfer permission information of the content information returned from the mobile terminal in response to the transmission of the transfer permission / refusal information, A transfer means for transferring the address of the register to the bulletin board server is provided, and the content information is acquired by the information terminal accessing the content server based on the address transferred to the bulletin board server.

In this case, when the transfer means receives the transfer instruction information instructing the immediate transfer of the content information returned from the portable terminal in response to the transmission of the transfer permission / prohibition information, the transfer means receives the transfer instruction information and the address of the register. The information is transferred to the bulletin board server, and the bulletin board server calls the information terminal when the transfer instruction information is received. Also, when the content information returned from the content server is input, the control means compresses this content information and sends it to the mobile terminal.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention is a We once accessed by a browser phone which is a mobile phone equipped with a browser.
It provides a system that allows information on the b site to be transferred to the bulletin board of the bulletin board server. In this system, the transferred information can be accessed again at any time and any number of times and the browser phone has It is possible to further improve the convenience of "handiness".

There are portal sites that have a proxy server accessed by browser phone. Web by browser phone
Use this proxy server to access the site. At the portal site, a transfer destination address (bulletin board or URI of the ftp site or mail account) is registered and managed for each user as information of the contract user. At the portal site, the transfer approval confirmation notation is added to the passing content to confirm the user's transfer intention. The portal site may have a function of compressing passing contents.

Further, the portal site has a plurality of registers for storing the storage source URI address of the content to be transferred, and can enter the storage address of the information intended by the content holder in the procedure with the content holder. Further, the portal site can send control information instructing the content storage source URI address and the type of collection method to the transfer destination address of the user. For the transfer request from the terminal, types such as transfer time and transfer method can be set. The CGI is used between the portal site server and the content server to fill in the storage source address.

The present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing the configuration of an information transfer system according to the present invention. This system includes a content server 1, a proxy server 3, a bulletin board server 5, and terminals 4 and 6. Here, the content server 1, the proxy server 3, and the bulletin board server 5 are all Internet 2.
It is installed on the top and can communicate with each other. The terminal 4 is a personal digital assistant having the proxy server 3 as a connection point to the Internet 2, for example, the above-mentioned browser phone.
The terminal 6 is an information terminal that uses the bulletin board server 5 as a connection point to the Internet 2 and uses the bulletin board function as a window for inputting / outputting information to / from the Internet, and is, for example, a personal computer (PC).

By the way, the bulletin board function described above is like a post office box protected by a registered password, and is a storage memory on the network that can exchange information with those who know the password (including the user himself). , Has an identification number (URI-U) for accessing. Here, the terminal 4 and the terminal 6 are generally used by the same user, and the proxy server 3 has a bulletin board identification number (URI-U) for each user established in the bulletin board server 5,
A password for access is registered and stored in advance.

When accessing the home page (HP) on the content server 1 from the terminals 4 and 6, the identification number URI-C of the home page is designated and information is taken out by a protocol such as HTTP. However, since the terminal 4 is a terminal that emphasizes portability and has a small display area, if the information on the homepage designed for the relatively large screen of the terminal 6 is accessed as it is, the display is too small to read or the screen design collapses. In many cases, it does not make sense. Therefore, software that compresses the content exclusively for the terminal 4 is sold. For such compression, a method of reducing large-sized information such as an image, or passing only an item in a text sentence and deleting the text is used. Also in this system, this type of compression function is installed in the proxy server 3. If a dedicated home page for the terminal 4 is open, the information from the content server 1 is not compressed for that content.
Leave it as it is.

FIG. 2 is a functional block diagram of the proxy server 3 which constitutes this system. The proxy server 3 is
As shown in FIG. 2, an interface between the terminal I / F unit 21, which is an interface with the terminal 4, a control statement adding unit 22, a compression processing unit 23, and the content server 1 or the bulletin board server 5. It consists of a server I / F unit 24 and an access destination register 20.

Here, the terminal 4 specifies the URI-C and accesses the home page HP of the content server 1 via the proxy server 3. In this case, when the terminal I / F unit 21 of the proxy server 3 recognizes that the code for accessing the URI-C is transmitted from the terminal 4, the server I / F unit 21
The access code is transferred to the content server 1 via the / F unit 24, and the URI-C is stored in the access destination unit 40 of the access destination register 20 secured for the terminal 4.

FIG. 4 shows the memory structure of the access destination register 20 prepared for each terminal 4. The access destination register 20 includes, as shown in FIG.
It has a detailed URI section 41 and an accessory URI section 42.

When the access code for accessing the URI-C is transferred from the terminal 4 when the home page HP of the content server 1 is accessed, the HTML content stored in the URI-C of the content server 1 is triggered by this access code. Is returned from the content server 1 to the server I / F unit 24 of the proxy server 3. In the proxy server 3, H received by the server I / F unit 24
When the compression processing unit 23 checks the TML content and detects a mark promised to the HTML content in advance, after the compression processing unit 23 compresses the HTML content, the control statement addition unit 22 further transfers the transfer permission text. Is added and transmitted from the terminal I / F unit 21 to the terminal 4. In addition, HTML from the content server 1
When the mark promised in advance cannot be detected in the content, the control text addition unit 22 adds the transfer permission text to the HTML content as it is without compressing the HTML content and directs it from the terminal I / F unit 21 to the terminal 4. Send.

FIG. 3 is a diagram showing a reception screen of the terminal 4 which receives the information transmitted from the content server 1 and passing through the proxy server 3. Reception screen 30 on the display unit of the terminal 4
As shown in FIG. 3, the contents display area 31
And a transfer permission text display area 32 are provided.

The URI of the content server 1 in which the image information is dropped in the content display area 31 of the display screen 30 of the terminal 4 and the amount of information of the text sentence is compressed only in the headline.
-HTML content from C is displayed. Then, in the transfer permission text display area 32 below the content display area 31, the transfer permission text added by the control text addition unit 22 of the proxy server 3, whether transfer is possible (transferred / not transferred), and transfer Timing (notification, accumulation),
Whether or not the supplementary information can be transferred (transferred / not transferred) is displayed. Here, the HTML content from the URI-C of the content server 1 is the compression processing unit 2 of the proxy server 3.
Content display area 3 if not compressed by 3
Although the original text is displayed in 1, the same transfer permission text as above is displayed in the transfer permission text display area 32.

The user of the terminal 4 judges the content of the displayed content display area 31 and, if interested, determines whether or not the content information displayed in the transfer text permission area 32 can be transferred, and If the content is urgent, the transfer timing is selected as “notification”, and it is found from the content of the content display area 31 that there is additional information, and if the additional information is acceptable, the additional information can be acquired. Select whether or not the information can be transferred, and click the send button. When the send button is clicked, the transfer control code including the above-mentioned selection parameters related to the transfer permission text is sent from the terminal 4 to the proxy server 3.

If the contents in the contents display area 31 are not urgent, the user of the terminal 4 selects "accumulation" as the transfer timing. Then, the transfer contents are accumulated in the bulletin board server 5 and can be viewed when the bulletin board is separately accessed by the terminal 6. Also,
When "Notify" is selected, the process of calling the terminal 6 from the bulletin board server 5 is started when the information is transferred to the bulletin board server 5, and the terminal 6 automatically and immediately accesses the bulletin board server 5. . In addition, when the permission / prohibition of the transfer of the additional information is selected as “Yes”, the additional information is separately taken from the content server 1 and transferred to the bulletin board server 5. Further, when the propriety of transferring the supplementary information is set to “No”, the supplementary information is not taken. By the way, when the proxy server 3 receives the above-mentioned transfer control code from the terminal 4,
The bulletin board server 5 is analyzed according to the case by analyzing the parameters.
Write the transfer information to the bulletin board URI-U of.

FIG. 5 is a diagram showing a format of transfer information written in the bulletin board server 5. Further, FIG. 6 is a flowchart showing an operation of writing transfer information to the bulletin board server 5 by the proxy server 3. The operation of the main part of this system will be described in detail based on the flowchart of FIG. 6 and the transfer information format of FIG. Proxy server 3
When receiving the transfer control code from the terminal 4, first determines in step S1 whether or not the content information included in the transfer control code can be transferred. Here, if the transferability of the content information is “NO”, the contents of the access destination register 20 are erased and the process ends in step S10 (nothing is written in the bulletin board server 5).

On the other hand, whether or not the content information can be transferred is "OK".
In the case of, the unique identification number of the transfer item is set in step S
At step S3, the time when the transfer control code is analyzed is stored in the identification number part 50 of FIG. 5 as a time stamp and stored in the time stamp part 51 of FIG. In this case, the identification code of “storage / notification” of the transfer timing received from the terminal 4 is transferred to the storage / notification unit (transfer timing unit) 52 of FIG. 5 as it is, and the access destination unit 53 of FIG.
The URI-C stored in the access destination section 40 of the access destination register 20 is transferred to (step S6).

However, in the procedure with the content server 1, if the proxy server 3 obtains more detailed content than the content from the URI-C of the content server 1 that the terminal 4 first accessed, the content information is stored. The address URI-C1 is stored in the detailed URI section 41 of the access destination register 20. Further, the address URI-C2, which stores the supplementary information sent when the user of the terminal 4 permits, is stored in the supplementary URI unit 42 of the access destination register 20. The storage information indicates the storage destination of the content information that the user wants to receive when the content holder accesses from the terminal 6 (PC) other than the mobile terminal 4.

Therefore, in the proxy server 3, even if the access destination section 40 of the access destination register 20 stores the URI-C, the detailed URI section 41 stores the URI-C1 and the determination in step S4 is "YES". If the access destination section 53 in FIG.
The URI-C1 of the detailed URI unit 41 is transferred instead of C (step S5). Here, when the URI-C1 is stored in the detailed URI unit 41 of the address destination register 20, it is generally the case that the URI-C of the access destination unit 40 is prepared with the content dedicated to the mobile terminal. If it is determined in step S7 that the additional information can be transferred, the URI-C2 of the additional URI unit 42 of the access destination register 20 is transferred to the additional information unit 54 of FIG.
After that, the proxy server 3 transfers to the bulletin board server 5 the transfer information in which the information is respectively written in the identification number part 50, the time stamp part 51, the storage / notification part 52, the access destination part 53 and the supplementary information part 54 in FIG. The information is transmitted and the bulletin board URI-U is made to write the transfer information (step S9).

The bulletin board server 5 saves the transfer information written in the bulletin board into a file for each case until the user accesses the terminal 6. However, the bulletin board server 5 stores the ID number of the terminal to be called for each bulletin board (for example, the ISDN number to which the terminal is connected). When the transfer timing included in the transfer information addressed to the bulletin board is "notification", as is generally known, ISDN DC
The H packet or the like is used to instruct to automatically start the terminal 6 and access the bulletin board. In this case, the terminal 6 automatically and immediately obtains the transfer information.

The user of the terminal 6 who accesses the bulletin board server 5 regardless of whether it is automatic or manual retrieves the stored transfer information file for each case and obtains its own information.
In this case, the user of the terminal 6 is U corresponding to the stored information of the transfer information written in the bulletin board in the access destination section 53 of FIG.
The RI-C or URI-C1 is accessed to retrieve the content information of the home page of the content server 1.
In the case of automatic, the received content information is stored in the cache memory. In the case of manual operation, you can continue to view the link information on the home page. In addition, as a result of looking at the link information on the homepage, if the user is particularly interested in the supplementary information, the transfer information written on the bulletin board is shown in FIG.
The URI-C2 corresponding to the storage information of the supplementary information section 54 is accessed to retrieve the relevant supplementary information of the content server 1. In the case of automatic, the incidental information can be automatically taken over. The information collection process in the terminal 6 described above is similar to the procedure for accessing the URI registered in the bookmark generally used in the Web browser.

Depending on the contract, the bulletin board server 5 analyzes the transfer information and collects the supplementary information from the terminal 6 to the terminal 6.
It is also possible to perform on behalf of the content server 1
The load balancing effect of can be improved. Further, by preparing a bulletin board for each of notification / accumulation / accompanying information in the bulletin board server 5 in advance, the proxy server 3 selects the bulletin board and writes the transfer information according to the selection parameter of the transfer control code received from the terminal 4. It is also possible to provide a range of access levels from the terminal 6. Further, as a means for sending the transfer information to the bulletin board server 5, a means by mail is also possible. In this case, a mail account is used instead of URI-U, and the transfer information is handled as an attachment file of the mail.

As described above, in the present system, the information of the website accessed once by the browser telephone and the instruction of the access procedure are transferred to the bulletin board dedicated to the user and stored, so that the transferred information can be re-selected at any time. It can be accessed any number of times on the terminal, and the convenience of the browser phone is further improved.
