Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a Web page display screen sharing system for displaying the same Web page in cooperation with a WWW browser among a plurality of computer terminals.
[0002]
[Prior art]
Web page display processing by a WWW browser is originally an independent process for each browser, but there is a Web page display screen sharing system capable of displaying the same Web page in cooperation from browsers activated on different terminals.
[0003]
As a system for sharing such a Web page, there is a “collaborative work system and recording medium” (Japanese Patent Laid-Open No. 2000-112862). In this conventional system, a WWW server that returns a corresponding Web page in response to a request from a browser, a server that returns all client names in response to a request for all client names from the browser, and a request for a shared screen to the WWW server Displays the shared screen and control screen that are sent back and sends a request for the names of all clients connected to the server in response to the display of the control screen, and displays the names of all returned clients on the control screen. A browser for display is provided, and a plurality of browsers and a WWW server are connected to a network to perform cooperative work.
[0004]
For example, a securities company has a site on the Internet and also provides an online help desk service. When a customer who does not know how to use the information provided on the site asks the help desk operator to share the browser display screen, the help desk operator links the Web page displayed on the operator's browser. A synchronous display processing applet (program) for controlling display in the synchronous mode to be displayed on the customer's browser and the URL of the Web page to be displayed are transmitted to the customer terminal. In the customer's browser, the Web page is displayed in conjunction with the operation of the operator who has the authority to operate the display screen. The operator uses the display screen in the synchronous mode to explain the site operation method and information content to the customer.
[0005]
[Problems to be solved by the invention]
However, in the conventional Web page display screen sharing system, only the computer terminal that receives the display screen sharing request can cancel the display screen sharing state, and the computer terminal that requested the display screen sharing cancels the sharing state. I couldn't.
[0006]
For example, in the above-mentioned help desk service of a securities company, the URL of the Web page displayed in the synchronization mode on the customer side browser is notified from the server side (operator side). Even if the operator wants to end the mode, the customer cannot cancel the display processing control in the synchronous mode and perform the normal display processing operation unless the operator ends the display processing control in the synchronous mode.
[0007]
In addition, when the synchronous mode display is canceled, the page information displayed in the WWW browser during the synchronous mode is also cleared, so the customer displays the Web page displayed during the synchronous mode again in the asynchronous mode. In order to do so, it was necessary to input the page information (URL) of the Web page anew.
[0008]
In the conventional Web page display screen sharing system, there is a dedicated or specific login page on the customer side as well as the operator, and it is necessary to display this specific login page and switch to the synchronous mode. For this reason, it has not been possible to smoothly switch from the Web page to the synchronous mode only when help support is required among many Web pages.
[0009]
Further, in the conventional web page display screen sharing system, when the mode is switched from the asynchronous mode to the synchronous mode, the operator takes the initiative in the operation, so that an operation for leading to a page requiring help occurs. At the time of switching the mode, there was no means to convey to the operator a page requiring help by the customer.
[0010]
Operations for Web page display processing in a WWW browser are individual tasks, and a Web page display screen sharing system that can easily switch from asynchronous mode to synchronous mode and from synchronous mode to asynchronous mode is desired. It has been.
[0011]
The present invention has been made in view of the above problems, and its purpose is to switch from asynchronous mode (normal display processing state) to synchronous mode for processing to display a Web page with a WWW browser, and synchronous mode. It is to provide a Web page display screen sharing system that seems to be seamlessly switched from asynchronous mode to asynchronous mode.
[0012]
Furthermore, an object of the present invention is to provide a Web page display screen sharing system which can be switched from the synchronous mode to the asynchronous mode, that is, the synchronous mode display can be canceled from the synchronous mode request side.
[0013]
Furthermore, an object of the present invention is to provide a Web page display screen sharing system capable of displaying a plurality of Web pages displayed during the synchronous mode even in the asynchronous mode after the synchronous mode is canceled.
[0014]
[Means for Solving the Problems]
In order to achieve the above object, the present invention includes a WWW server that returns a corresponding Web page in response to a display request and a WWW browser that displays the Web page, and displays the same Web page in cooperation with each other. A relay server that relays information exchange between the computer terminal and the WWW server in a system in which a plurality of users share a display screen of the same Web page with a plurality of computer terminals that display Web pages in a synchronous mode. The relay server receives a login request to the synchronous mode from the computer terminal and page information at the time of login of the Web page displayed on the WWW browser at the time of login, and displays the Web page in cooperation with the synchronous mode. Register two or more computer terminals as a group, and User information registration means for storing identification information of a computer terminal in user information storage means, and for synchronization to make a display request to the WWW server in response to a login page information or Web page display request from the computer terminal that requested the login Page request means, cache page creation means for creating a cache page based on the corresponding Web page acquired from the WWW server, and storing the cache page in the cache page storage means, page information of the Web page, and the cache Page information management means for associating the page information of the page with the page information storage means, cache page delivery means for delivering the cache page to the computer terminals of the group to which the computer terminal that requested the display belongs, and the computer Terminal The page information of the Web page corresponding to the cache page that was displayed when the logout request was accepted when the logout request was received from the synchronous mode, or the cache page that was displayed in cooperation with the synchronous mode during the synchronous mode Logout information sending means for sending logout information including page history information of the web page corresponding to the log, and the computer terminal is a login processing means for sending a login request to the synchronous mode and the login page information; The computer terminal is set in a synchronous mode, a Web page display request is sent to the relay server, a cache page related to the display request, or page information or page history information of the Web page is acquired from the relay server, and the WWW Synchronization to pass to browser Display control means, logout notification means for sending out a synchronous mode logout notification to the relay server, and synchronization display controller disappearing when the logout information is received from the relay server, canceling the synchronous mode by canceling the synchronous display control means And a processing means and a page display processing means for making a display request to the WWW server based on the page information or the page history information after the synchronization mode is released, and displaying the Web page acquired from the WWW server.
[0015]
In the present invention, when the relay server receives the login request to the synchronous mode and the login information including the page information of the Web page displayed at the time of login from the computer terminal having the WWW browser, The identification information is grouped and stored in the user information storage means.
[0016]
In the computer terminal, the synchronous display controller is downloaded from the relay server and automatically activated, and the WWW browser is set to the synchronous mode. In addition, the relay server sends a display request to the WWW server using the page information of the Web page at the time of login included in the login information, creates a cache page based on the acquired corresponding Web page, The page information storing means stores the page information in which the page information of the Web page and the page information of the cache page are associated with each other. Then, the cache page is distributed to the login request source computer terminal and the computer terminals of the same group as the computer terminal. The synchronous display controller of the computer terminal receives the cache page corresponding to the Web page being displayed at the time of the login request from the relay server and displays it.
[0017]
Thereafter, every time the relay server receives a Web page display request from the synchronous display controller of the computer terminal in the synchronous mode, it generates a cache page based on the corresponding Web page acquired from the WWW server by the received display request. The correspondence relationship between the page information of the Web page and the page information of the cache page is stored, and the process of distributing the generated cache page to each computer terminal of the group is repeated.
[0018]
Thereafter, when a logout request is received from the computer terminal in the synchronous mode, the page information storage unit is searched, and logout information including the page information of the web page corresponding to the cache page that has been displayed in cooperation with the logout is obtained. It transmits to the WWW browser of the computer terminal. Upon receiving the logout information, the computer terminal cancels the synchronous display controller and cancels the synchronous mode, requests display to the WWW server based on the page information included in the logout information, and displays the acquired web page.
[0019]
As described above, according to the present invention, in a system that shares a display screen of a Web page with a WWW browser, a page having the same content is displayed when switching from the asynchronous mode to the synchronous mode and when switching from the synchronous mode to the asynchronous mode. Thus, it is possible to provide a Web page display screen sharing system that seems to be seamlessly switched between modes.
[0020]
In addition, the synchronization mode display can be canceled from the computer terminal which is the synchronization mode request side.
[0021]

The synchronous mode switching button 437 is a button for starting a process of downloading the synchronous display controller 31 from the relay server 1 in order to switch from the asynchronous mode to the synchronous mode.
[0058]
When the customer selects / executes the synchronous mode switching button 437 by mouse click or the like, login information for synchronous login processing is notified to the relay server 1 by the login processing means 423 of the WWW browser 42. Then, the relay server 1 acquires login information and transmits the synchronous display controller 41.
[0059]
As a result, it is not necessary to use a special Web page browser provided with a synchronous display controller function in advance, or to incorporate a synchronous display controller into a WWW browser as a plug-in program, and a general WWW browser that displays a Web page is used. Thus, it is possible to easily shift to the display process in the synchronous mode.

[0062]
In the cache page display unit 442, a cache page acquired from the relay server 1 is displayed instead of the Web page. The cache page is configured to provide an asynchronous mode switching button 447.
[0063]
The asynchronous mode switching button 447 is a button for starting processing for notifying the logout from the relay server 1 in order to switch from the synchronous mode to the asynchronous mode. When the customer selects / executes the asynchronous mode switching button 447 by mouse click or the like, a logout notification is transmitted to the relay server 1 by the logout notification means 414 of the synchronous display controller 41.
[0064]
The asynchronous mode switching button 447 may be provided on the controller toolbar 441. Further, on the display screen in the synchronous mode when the synchronous display controller 41 is activated / executed, the browser toolbar 431 is not displayed as shown in FIG. 9 in order to avoid operational confusion. However, the tool bar 431 of the browser and the tool bar 441 of the controller may be displayed at the same time so that the state of whether or not the operation is possible can be distinguished.
[0065]
The processing flow of the present invention will be described below.
[0066]
FIG. 10 shows the flow of the switching process from the asynchronous mode to the synchronous mode when the operator logs in.
[0067]
When the operator terminal 3 notifies the WWW server 2 of a display request for the operator login page (page C1) by the asynchronous page request means 321 of the WWW browser 32 (step S1), the page C1 is returned from the WWW server 2. (Step S2). When the operator clicks the synchronization mode switching button 437 configured on the page C1, the login processing unit 323 transmits the synchronization login request and login information such as a predetermined ID to the relay server 1 to execute the synchronization login process. (Step S3).
[0068]
In the relay server 1, the login information transmitted from the operator terminal 3 is acquired, and the login information is added to the user list 61 by the user list changing unit 14. As a result, the identification information of the operator is recorded in the corresponding seat of the vacant seat and enters the standby seat (step S4).
[0069]
Then, the cache page creation means 12 creates a synchronization screen composed of the synchronous display controller 31 and the standby page (step S5), and the cache page distribution means 13 transmits this synchronization screen to the operator terminal 3 (step S5). S6).
[0070]
In the operator terminal 3, a synchronous screen is acquired from the relay server 1 by the page display processing unit 322 of the WWW browser 32, and the synchronous display controller 31 in the synchronous screen is acquired by the controller acquisition unit 324. Thereafter, the synchronous display controller 31 is activated to display a synchronous screen (standby screen) including a controller toolbar 441 and a standby page (step S7), and waits for customer login (step S8).
[0071]
FIG. 11 shows a flow of switching processing from the asynchronous mode to the synchronous mode when the customer logs in.
[0072]
While the operator terminal 3 is waiting for customer login (step SS8), the asynchronous page request means 421 of the WWW browser 42 of the customer terminal 4 sends a display request for a normal Web page (page A1) to the WWW server 2. (Step S10), the page A1 is returned from the WWW server 2 (Step S11). Furthermore, when the customer makes a transition to another Web page (page A2) that does not require help, the display request for page A2 is returned to the WWW server 2 by the asynchronous page request means 421 of the WWW browser 42 (step S12). ), Page A2 is returned from the WWW server 2 (step S13). The customer repeats the same processing and changes the Web page in the asynchronous mode.
[0073]
Here, it is assumed that the synchronous mode switching button 437 is provided on the page A3 displayed in the asynchronous mode, and that the customer's help is required while the customer is browsing the page A3. When the customer clicks the synchronization mode switching button 437, the login processing means 323 transmits the customer login protocol R1 to the relay server 1 to execute customer login (step S14).
[0074]
FIG. 12 shows a data configuration example of the protocol R1. The protocol R1 includes login information and displayed Web page information. The login information is, for example, a user identifier, an IP address, a password, and the Web page information being displayed is page information of the Web page currently displayed on the WWW browser 42 (such as the URL of the page A3).
[0075]
The relay server 1 acquires login information of the protocol R1 by the user list changing means 14 (step S15), inquires the operator information in the user list 61, and sets the corresponding seat where the operator is already set and the customer is not set. The acquired login information is set, and the corresponding seat to which the customer terminal 4 is connected is determined (step S16).
[0076]
Further, the web page request unit 11 transmits a display request to the WWW server 2 based on the information of the web page of the protocol R1 (URL of the page A3), and the WWW server 2 returns the page A3 (step S17). The cache page creation unit 12 generates a cache page B3 based on the page A3, and stores the URL of the page A3 and the URL of the cache page B3 in the page list 71 (step S18).
[0077]
Then, the cache page creation means 12 creates a synchronization screen composed of the synchronous display controller 41 and the cache page B3, and the cache page distribution means 13 transmits this synchronization screen to the operator terminal 3 (step S19).
[0078]
In the customer terminal 4, the synchronous screen is acquired by the page display processing unit 422 of the WWW browser 42, and the synchronous display controller 41 in the synchronous screen is acquired by the controller acquisition unit 424. Thereafter, the synchronous display controller 41 is activated to display the controller toolbar 441. Further, the cache page B3 is displayed by the cache page display processing means 412 of the synchronous display controller 41. Here, the cache page B3 is delivered and displayed by the cache page display processing means 412 to the page display processing means 422 of the WWW browser 42 (step S110).
[0079]
At the same time, the cache page delivery unit 13 transmits the cache page B3 to the operator terminal 3 (step S111), and the standby page is changed to the cache page B3 by the cache page display processing unit 312 of the synchronous display controller 31 of the operator terminal 3. (Step S112).
[0080]
As a result, the same cache page B3 corresponding to the Web page A3 is displayed on the screen displayed on the customer terminal 4 and the operator terminal 3. Then, since a cache page corresponding to the Web page related to the display request is transmitted to the synchronous display controllers 31 and 41 of both terminals, a synchronous mode in which the display transitions in cooperation is realized.
[0081]
In the terminal, the Web page A3 displayed on the WWW browsers 32 and 42 and the cache page B3 displayed under the control of the synchronous display controllers 31 and 41 have the same contents. It seems that the display screen has seamlessly shifted to synchronous mode.
[0082]
FIG. 13 shows the flow of page transition processing during the synchronous mode.
[0083]
While the page display processing of the customer terminal 4 and the operator terminal 3 is in the synchronous mode, the page transition is made from the currently displayed cache page B3 to the page A4 by the operation on the operator terminal 3. The page information for transition (URL of page A4) and its display request are transmitted to the relay server 1 by the synchronization page request means 311 (step S20).
[0084]
In the relay server 1, when the page information is acquired by the Web page request unit 11 and a display request for the page A4 is transmitted to the WWW server 2 (step S21), the WWW server 2 returns the page A4 (step S22). Then, the cache page creation unit 12 creates a cache page B4 based on the page A4, and stores the URL of the page A4 and the URL of the cache page B4 in the page list 71 (step S23). Further, the cache page B4 is transmitted to the synchronous display controllers 31 and 41 of the operator terminal 3 and the customer terminal 4 (step S24). In each of the synchronous display controllers 31, 41, the cache page display processing means 312, 412 changes the display to the cache page B4 received from the currently displayed cache page B3 (step S25).
[0085]
Further, when a page transition from the Web page A4 to the Web page A5 and from the Web page A5 to the Web page A6 occurs by the operation of the operator, the relay server 1 relays these page information through the same processing. Then, cache pages B5 and B6 corresponding to the Web pages A5 and A6 acquired from the WWW server 2 are created and transmitted to the operator terminal 3 and the customer terminal 4 (steps S20 to S24). The synchronous display controllers 31 and 41 of each terminal change the display to the acquired cache page (steps S26 and S27).
[0086]
Further, whenever the cache page creation unit 12 of the relay server 1 creates a cache page based on the display request, the URL (page information of the web page) of the page list 71 and the cache (page information of the created cache page) are displayed. Update items. Note that the cache page creation unit 12 may add page information of Web pages corresponding to the cache page creation order, and the history information may be stored in the page list 71.
[0087]
As described above, when the operator operates the page transition during the synchronous mode, the page displayed on the customer terminal 4 also changes in cooperation, so that the customer receives the explanation of the operator while confirming the transition page. Can do.
[0088]
Furthermore, when the Internet telephone function and the chat function are incorporated in the display screen 440 of the synchronous mode displayed by the synchronous display controllers 31 and 41, the contents of the displayed page are explained between the customer and the operator. Receiving, navigating for page transitions, proxy input by the operator, and pointing and instruction by the marker function.
[0089]
FIG. 14 shows a flow of the switching process from the synchronous mode to the asynchronous mode when the customer logs out.
[0090]
It is assumed that the explanation of the operator ends while the cache page B6 is displayed, and the customer logs out from the synchronous mode. The logout notification means 414 of the synchronous display controller 41 of the customer terminal 4 transmits a logout request to the relay server 1 (step S30). In the relay server 1, the user list changing unit 14 clears and updates the corresponding customer information from the user list 61 (step S31).
[0091]
Further, the logout time information sending means 15 generates a protocol R2 with reference to the page list 71, and transmits the protocol R2 to each of the synchronous display controllers 31 and 41 of the operator terminal 3 and the customer terminal 4 to notify the logout (step). S32, S33).
[0092]
FIG. 15 shows a data configuration example of the protocol R2. The protocol R2 includes a logout notification and Web page information. The Web page information is page information (such as the URL of the page A6) of the Web page corresponding to the cache page B6 displayed in the synchronous mode at the time of logout notification. Further, the Web page information may be Web page history information corresponding to all cache pages displayed during the synchronization mode.
[0093]
When the synchronous display controller 41 of the customer terminal 4 receives the protocol R2, the controller disappearing processing means 415 passes the Web page information (URL of the page A6) to the WWW browser 42 and then deletes the synchronous display controller 41 itself. Is performed (step S34).
[0094]
In the WWW browser 42, the asynchronous page request means 421 makes a display request to the WWW server 2 based on the received URL of the page A6 (step S35), and the WWW server 2 returns the page A6 (step S36). The page A6 is displayed by the display processing means 422 (step S37).
[0095]
When the synchronous display controller 31 of the operator terminal 3 receives the protocol R2, the standby screen display means 310 returns the cache page B6 to the standby page display (step S38), displays the standby page, and waits for customer login. (Step S39).
[0096]
As a result, the customer can cancel the synchronization mode at any time by logout operation from the customer terminal 4 when browsing in the synchronous mode is no longer necessary, such as when the explanation of the operator is finished.
[0097]
The WWW browser 42 of the customer terminal 4 displays the page A3 when logging in to the synchronous mode, but when logging out of the synchronous mode, that is, when returning to the asynchronous mode, the page displayed at the end of the synchronous mode. The same page A6 as B6 is displayed. Thus, since the same page is displayed at the time of transition from the synchronous mode to the asynchronous mode, it seems to the customer that the display change from the synchronous mode to the asynchronous mode is seamlessly performed.
[0098]
Note that the WWW browser 42 of the customer terminal 4 can also receive the history information of the Web page displayed during the synchronous mode from the synchronous display controller 41 when logging out of the synchronous mode. In this case, the WWW browser 42 displays the page A6 when logging out of the synchronization mode, but by clicking the previous page display button 433 on the browser toolbar 431, the history information of the page displayed during the synchronization mode is displayed. Based on the page, the page can be changed from page A6 to page A5 and from page A5 to page A4. Thus, the customer can confirm the contents received from the operator in the synchronous mode by changing the page at his / her own pace again.
[0099]
FIG. 16 shows the flow of switching processing from the synchronous mode to the asynchronous mode when the customer logs out with the permission of the operator.
[0100]
It is assumed that the explanation of the operator ends while the cache page B6 is displayed, and the customer logs out from the synchronous mode. The logout notification means 414 of the synchronous display controller 41 of the customer terminal 4 transmits logout request and logout information such as a predetermined user ID to the relay server 1 (step S40). In the relay server 1, logout information sending means 15 sends logout information from the customer to the synchronous display controller 31 of the operator terminal 3 (step S41).
[0101]
In the operator terminal 3, the customer logout permission determination means 313 of the synchronous display controller 31 determines whether or not to permit the logout request based on the received logout information. If yes (YES), the logout permission is relayed. The server 1 is notified (step S42).
[0102]
In the relay server 1, when logout permission is received from the operator terminal 3, the user list changing unit 14 clears and updates the corresponding customer information from the user list 61 (step S43). Further, the logout time information sending means 15 refers to the page list 71 to generate the protocol R2 and notifies the synchronous display controllers 31 and 41 of the operator terminal 3 and the customer terminal 4 (steps S44 and S45). Subsequent processing steps S46 to S411 are the same as steps S34 to S39 shown in FIG.
[0103]
In this way, by notifying the operator terminal 3 of the logout notification received from the customer terminal 4 by the relay server 1, it is possible to prevent the customer from logging out of the synchronous mode without permission. When a plurality of customer terminals 4 and operator terminals 3 are linked and displayed as a group in a synchronous mode, etc., only one customer terminal 4 is required to switch the display modes on the customer terminals 4 in the group. Can be prevented from logging out of the synchronous mode.
[0104]
FIG. 17 shows a flow of switching processing from the synchronous mode to the asynchronous mode when the operator logs out.
[0105]
It is assumed that when the operator leaves the corresponding seat, logout in the synchronous mode is performed from the operator terminal 3. The logout notification means 314 of the synchronous display controller 31 of the operator terminal 3 transmits logout information including a logout request and a predetermined operator ID to the relay server 1 (step S50). In the relay server 1, the user list changing means 14 clears and updates the corresponding operator information from the user list 61 (step S51).
[0106]
Further, the logout time information sending means 15 transmits a logout notice to the synchronous display controller 31 of the operator terminal 3 (step S52).
[0107]
When receiving the logout notification, the synchronous display controller 31 of the operator terminal 3 passes the page information of the login page (URL of the page C1) to the WWW browser 32 by the controller disappearing processing unit 315, and then deletes the synchronous display controller 31 itself. Is performed (step S53). In the WWW browser 32, the asynchronous page request means 321 makes a display request to the WWW server 2 based on the URL of the page C1 (step S54), and the WWW server 2 returns the page C1 (step S55). Then, the page C1 (login page) is displayed by the page display processing means 322 (step S56).
[0108]
FIG. 18 shows an operation flow at the time of switching from the asynchronous mode to the synchronous mode at the customer terminal 4.
[0109]
At the customer terminal 4, the customer requests display of the page A1 to the WWW server 2 on the display screen 430 as shown in FIG. 8 (step S60), and subsequently requests display of the pages A2 and A3 (step S60). S61). Since the operator's help is required while the page A3 is displayed, the login information is notified to the relay server 1 by clicking the synchronization mode switching button 437 on the page A3 and the login processing to the synchronization mode is performed (step S62). .
[0110]
In the relay server 1, it is determined whether or not a compatible operator already exists (step S 63). If there is an operator, the downloaded synchronous display controller 41 is activated in the customer terminal 4, and FIG. A display screen 440 as shown in FIG. Further, the cache page B3 for the synchronous mode is displayed on the cache page display unit 442 of the display screen 440 (step S64). If there is no operator, a login failure screen (not shown) is displayed, and re-login processing is performed after the operator's corresponding seat is available (step S65).
[0111]
FIG. 19 shows a flow of operations at the time of switching from the synchronous mode to the asynchronous mode at the customer terminal 4.
[0112]
When the synchronous mode page B6 is displayed on the display screen 440 as shown in FIG. 9 at the customer terminal 4, the customer logs out to the relay server 1 by clicking the asynchronous mode switching button 447 (step S70). Is notified (step S71).
[0113]
As a result of the logout process performed by the relay server 1, the synchronous display controller 41 receives the page information (URL of the page A6) displayed at the time of logout as the protocol R2 and passes it to the WWW browser 42. The WWW browser 42 issues a display request for the page A6 corresponding to the page B6 to the WWW server 2 (step S72). After the synchronous display controller 41 is deleted, the WWW browser 42 displays the asynchronous mode page A6 on the page display unit 432 of the display screen 430 (step S73).
[0114]
As mentioned above, although this invention was demonstrated by the embodiment, this invention can be variously deformed in the range of the main point.
