BACKGROUND OF THE INVENTION
The present invention relates to an information transfer system and information transfer method for transferring content information.
[0002]
[Prior art]
In recent years, a mobile phone is equipped with a browser, and Internet Web access 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, and provides the convenience of easily accessing the Web anytime, anywhere. With the widespread use of browser phones, content holders (CHs) such as companies and shops that provide information to Web users with the aim of acquiring business users can access their websites. It is a pleasure to have more opportunities to receive.
[0003]
[Problems to be solved by the invention]
However, browser phones are considered to be inferior to personal computers (PCs) in the future in terms of display and signal processing capabilities due to restrictions on portability, power supply, etc., and the information they send will eventually be left on a personal computer. It can't meet the demands of the vast majority of content holders who want them to see. In addition, content that has also attracted interest for browser phone users is to select a terminal according to the TPO and separately access the details of the information.
[0004]
On the other hand, personal computers are in the direction of strengthening cooperation with network services connected to networks and provided by Internet service providers (ISPs). In particular, in the service that acts as an agent for the establishment and operation of a dedicated homepage (HP) for each contracted user, called a personal homepage (PHP), a receiving point for information such as a bulletin board is used on the network as a place for authorized users to exchange information. 24 hours a day. The user of the personal computer can retrieve the input information at any time by accessing this bulletin board.
[0005]
The present invention has been made in view of the above problems, and the object of the present invention is to make it possible to access information on an Internet website once accessed by a browser phone by an arbitrary terminal such as a personal computer. There is to do.
[0006]
[Means for Solving the Problems]
The present invention in order to solve such a problem, a proxy server capable of content servers and bulletin board server and communicate with each other via a network, a first terminal connected to the proxy server and the browser is mounted In the system consisting of the second terminal connected to the bulletin board server and equipped with the browser , the proxy server stores the address of the content server accessed when accessing the content server of the first terminal When the content information returned from the content server in response to the access to the content server of the first terminal is received , transfer permission / prohibition information including whether or not the content information can be transferred is added to the content information . of return of the control means for transmitting to the terminal from the first terminal to the transmission of the transfer license availability information That receives the transfer-friendly information of the content information, and a transfer means for transferring the address of the register to the bulletin board server, the second terminal accesses the content server based on the address transferred to the bulletin board server, the content information It is something to get.
[0007]
In this case, when the transfer means receives the transfer instruction information for instructing the immediate transfer of the content information returned from the first terminal in response to the transmission of the transfer permission / prohibition information, the transfer means displays the transfer instruction information and the address of the register.

[0008]
DETAILED DESCRIPTION OF THE INVENTION
The present invention provides a system that makes it possible to transfer information on a website once accessed by a browser phone, which is a mobile phone equipped with a browser, to a bulletin board of a bulletin board server. It can be accessed again and again anytime from any terminal, and the convenience of browser phone can be further improved.
[0009]
There is a portal site with a proxy server that is accessed via a browser phone. When accessing a Web site with a browser phone, the proxy server is used. The portal site registers and manages a forwarding address (URI or mail account of a bulletin board or ftp site) for each user as contract user information. In the portal site, a transfer permission confirmation notation is added to the passing content, and the user's intention to transfer is confirmed. A portal site may have a compression function for passing content.
[0010]
Further, the portal site has a plurality of registers for storing the storage URI addresses of contents to be transferred, and can enter the storage address of information intended by the contents holder in the procedure with the contents holder. Also, the portal site can send control information indicating the content storage source URI address and the type of collection method to the transfer destination address of the user. The transfer request from the terminal can be set with types such as transfer time and transfer method. CGI is used between the portal site server and the content server to enter the storage source address.
[0011]
The present invention will be described below with reference to the drawings.
FIG. 1 is a block diagram showing a 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 installed on the Internet 2 and can communicate with each other. The terminal 4 is a portable information terminal having the proxy server 3 as a connection point to the Internet 2, for example, the above-described 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 a personal computer (PC), for example.
[0012]
By the way, the bulletin board function mentioned above is like a PO 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 users themselves) and access it. Has an identification number (URI-U). 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 and access. The password is registered and stored in advance.
[0013]
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 extracted by a protocol such as HTTP. However, the terminal 4 is a terminal that places importance on 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 be read or the screen design is corrupted. Often does not make sense. Therefore, software for compressing contents dedicated to the terminal 4 is sold. Such compression uses methods such as reducing large-size information such as images or deleting only text items and allowing text to be deleted. This type of compression function is also installed in the proxy server 3 in this system. If a dedicated home page for the terminal 4 is established, information from the content server 1 is not compressed and the content is passed through as it is.
[0014]
FIG. 2 is a functional block diagram of the proxy server 3 constituting this system. As shown in FIG. 2, the proxy server 3 includes a terminal I / F unit 21 that is an interface with the terminal 4, a control statement adding unit 22, a compression processing unit 23, the content server 1 or the bulletin board server 5 And a server I / F unit 24 that is an interface between the access point and the access destination register 20.
[0015]
Here, the terminal 4 designates 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 access code is transferred to the content server 1 via the server I / F unit 24. At the same time, this URI-C is stored in the access destination section 40 of the access destination register 20 reserved for the terminal 4.
[0016]
FIG. 4 shows a memory structure of the access destination register 20 prepared for each terminal 4. As shown in FIG. 4, the access destination register 20 includes the above-described access destination unit 40, detailed URI unit 41, and incidental URI unit 42.
[0017]
When an access code for accessing the URI-C is transferred from the terminal 4 when accessing the home page HP of the content server 1, the HTML content stored in the URI-C of the content server 1 is triggered by this access code. 1 is returned to the server I / F unit 24 of the proxy server 3. In the proxy server 3, the HTML content received by the server I / F unit 24 is checked by the compression processing unit 23, and when a mark promised in advance in the HTML content is detected, the compression processing unit 23 performs compression processing of the HTML content. Then, the control sentence adding unit 22 adds a transfer permission sentence and transmits it from the terminal I / F unit 21 to the terminal 4. Also, if a mark promised in advance in the HTML content from the content server 1 cannot be detected, the HTML content is not subjected to compression processing, and a transfer permission text is added to the HTML content as it is by the control text adding unit 22 so that the terminal I / F Transmitting from the unit 21 to the terminal 4.
[0018]
FIG. 3 is a diagram illustrating a reception screen of the terminal 4 that has received information transmitted from the content server 1 and passing through the proxy server 3. As shown in FIG. 3, the reception screen 30 of the display unit of the terminal 4 is provided with a content display area 31 and a transfer license text display area 32.
[0019]
In the content display area 31 in the display screen 30 of the terminal 4, the HTML content from the URI-C of the content server 1 in which the image information is dropped and the amount of information is compressed only for the headline of the text sentence is displayed. In the transfer permission text display area 32 below the content display area 31, the transfer permission text added by the control text adding unit 22 of the proxy server 3, whether transfer is possible (transfer / do not transfer), transfer The timing (notification, storage), whether or not the accompanying information can be transferred (transfer / do not transfer), and the like are displayed. Here, when the HTML content from the URI-C of the content server 1 is not compressed by the compression processing unit 23 of the proxy server 3, the original text is displayed in the content display area 31, but the transfer permission text display area 32 is displayed. Displays the same transfer permission text as above.
[0020]
The user of the terminal 4 determines 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 the content. 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 it is acceptable to collect the additional information, whether the additional information can be transferred Select “Yes” and click the Send button. When the transmission button is clicked, the transfer control code including the selection parameter related to the transfer permission text is transmitted from the terminal 4 to the proxy server 3.
[0021]
If the contents of the content display area 31 do not require urgent, the user of the terminal 4 selects “accumulation” as the transfer timing. Then, the transfer contents are stored in the bulletin board server 5 and can be viewed when the bulletin board is accessed separately by the terminal 6. When “notification” is selected, a 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. become. Further, when “Yes” is selected for whether or not the accompanying information transfer is possible, the accompanying information is separately taken from the content server 1 and transferred to the bulletin board server 5. In addition, when the incidental information transfer permission / inhibition is set to “No”, the incidental information is not collected.
By the way, when the proxy server 3 receives the transfer control code described above from the terminal 4, it analyzes the parameters and writes the transfer information to the bulletin board URI-U of the bulletin board server 5 according to the case.
[0022]
FIG. 5 is a diagram showing a format of transfer information written in the bulletin board server 5. FIG. 6 is a flowchart showing the transfer information writing operation to the bulletin board server 5 by the proxy server 3. Based on the flow chart of FIG. 6 and the transfer information format of FIG.
When the proxy server 3 receives the transfer control code from the terminal 4, it first determines whether or not the content information included in the transfer control code can be transferred in step S1. Here, if the transferability of the content information is “NO”, the contents of the access destination register 20 are erased in step S10 and the process is terminated (nothing is written in the bulletin board server 5).
[0023]
On the other hand, when the transferability of the content information is “permitted”, the unique identification number of the transfer case is stored in the identification number portion 50 of FIG. 5 in step S2, and the time when the transfer control code is analyzed is determined in step S3. The time stamp is stored in the time stamp unit 51 of FIG. In this case, the transfer timing “accumulation / notification” identification code received from the terminal 4 is directly transferred to the accumulation / notification unit (transfer timing unit) 52 of FIG. 5, and the access destination register 53 of FIG. The URI-C stored in the 20 access destination units 40 is transcribed (step S6).
[0024]
However, when the proxy server 3 obtains more detailed content than the content from the URI-C of the content server 1 accessed by the terminal 4 in the procedure with the content server 1 first, the proxy server 3 stores the content URI- C1 is stored in the detailed URI section 41 of the access destination register 20. In addition, the address URI-C2 in which auxiliary information to be sent when the user of the terminal 4 permits is stored in the auxiliary URI unit 42 of the access destination register 20. The storage information indicates the storage location of the content information that the user wants to receive when accessing from a terminal 6 (PC) whose content holder is not the portable terminal 4.
[0025]
Therefore, even if URI-C is stored in the access destination section 40 of the access destination register 20, the proxy server 3 stores the URI-C1 in the detailed URI section 41 and the determination in step S4 is “YES”. The URI-C1 of the detailed URI unit 41 is transferred to the access destination unit 53 of FIG. 5 instead of the URI-C of the access destination unit 40 (step S5). Here, when the URI-C1 is stored in the detailed URI unit 41 of the address destination register 20, the URI-C of the access destination unit 40 is generally a case where content dedicated to a portable terminal is prepared. If it is determined in step S7 that the transfer of incidental information is possible, the URI-C2 of the incidental URI section 42 of the access destination register 20 is transferred to the incidental information section 54 of FIG. Thereafter, the proxy server 3 sends the transfer information in which information is written in the identification number part 50, the time stamp part 51, the storage / notification part 52, the access destination part 53, and the incidental information part 54 of FIG. Then, the transfer information is written in the bulletin board URI-U (step S9).
[0026]
The bulletin board server 5 converts the transfer information written on the bulletin board into a file for each case and stores it 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”, the terminal 6 is automatically activated to access the bulletin board using the ISDN D-CH packet or the like as is generally known. Instruct. In this case, the terminal 6 automatically and immediately obtains the transfer information.
[0027]
Regardless of automatic or manual operation, the user of the terminal 6 accessing the bulletin board server 5 retrieves the stored transfer information file one by one and obtains his / her information. In this case, the user of the terminal 6 accesses the URI-C or URI-C1 corresponding to the information stored in the access destination part 53 of FIG. . In the case of automatic, the collected content information is stored in the cache memory. In addition, in the case of manual operation, the link information of the home page can be continuously viewed. Further, as a result of looking at the link information on the home page, in particular, when interested in the supplementary information, the content is accessed by accessing the URI-C2 corresponding to the storage information in the supplementary information section 54 of FIG. 5 of the transfer information written on the bulletin board. The corresponding incidental information of the server 1 is collected. In the case of automatic, it is possible to automatically collect the incidental information. The information collection process at the terminal 6 described above is similar to the procedure for accessing a URI registered in a bookmark generally used in a Web browser.
[0028]
Depending on the contract, it is also possible for the bulletin board server 5 to act on behalf of the terminal 6 until the transfer information is analyzed and the incidental information is collected, and the load distribution effect of the content server 1 can be improved. it can. In addition, the bulletin board server 5 prepares bulletin boards individually for each of notification / accumulation / accompanying information, and 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. Furthermore, as means for sending the forwarding information to the bulletin board server 5, a means by mail is also possible. In this case, a mail account is used instead of the URI-U, and the forwarding information is handled as an attached file of the mail.
[0029]
In this way, in this system, information on websites that have been accessed once via a browser phone and instructions for access procedures are transferred and stored on a dedicated bulletin board, so that the transferred information can be changed anytime on any terminal. It can be accessed at any time, and the convenience of “easy” that a browser phone has is further improved.
[0030]
【The invention's effect】
As described above, according to the present invention, a content server, a proxy server, and a bulletin board server, each of which is arranged on the Internet and capable of mutual communication, are provided. In the system connected to the bulletin board server, the proxy server stores the address of the content server accessed when accessing the content server of the mobile terminal in the register, and the content according to the access to the content server of the mobile terminal. When the content information stored at the address of the server is returned, the transfer permission permission / inhibition information including the transfer permission / inhibition of the content information is added to the content information and transmitted to the portable terminal to be displayed on the display screen of the portable terminal. Along with the transfer permission information On the other hand, when the transferability information of the content information returned from the portable terminal is received, the address of the register is transferred to the bulletin board server, so the information terminal side sets the content server based on the address transferred to the bulletin board server. By accessing, content information can be acquired. Therefore, the content information on the Internet website once accessed by the mobile terminal which is a browser phone is accessed on the information terminal side which is an arbitrary terminal such as a personal computer. be able to.
