  The web page generation unit 61 has a function of converting the input from the key input interface 73 into a web page, and the result is output to the screen display unit 71 directly or via the web browser 55. The created web page can be stored in the storage unit 57 in the IP telephone terminal (operator) 5 or can be sent to the temporary web server 11 controlled by the temporary web server control unit 63.

  FIG. 10 is a diagram showing a more specific appearance configuration example 210 of the IP telephone terminal (operator) 5 according to the present embodiment.

  The main body is integrated with a large monitor 213, and the voice input / output unit is a headset 215. The key input unit is composed of a keyboard 217 and a mouse 221 for easy operation, and has the same appearance as a so-called personal computer.

  FIG. 4 is an example of a display screen 81 that displays advertisement information related to a tour provided by a travel agency at the IP telephone terminal (customer) 3. This advertising information is constituted by Web content on the content Web server 15. The information may be displayed on the Web browser 25 of the IP telephone terminal (customer) 3, or the advertisement information may be a TV program and the IP telephone terminal (customer) 3 may have a TV viewing function. Further, the advertisement information may be displayed on a device other than the IP telephone terminal (customer) 3. The advertisement information includes the IP telephone number of the IP telephone terminal (operator) 5 for making a call to the travel agency. The IP telephone number of the IP telephone terminal (operator) 5 is displayed on a display screen of a device (not shown) other than the IP telephone terminal (customer) 3 or the IP telephone terminal (customer) 3. The customer may make a call by inputting the displayed IP telephone number to the IP telephone terminal (customer) 3. Alternatively, when the advertising information is composed of Web contents and has an IP telephone number inside the contents, the IP telephone terminal (customer) 3 is not displayed by the IP telephone terminal (customer) 3 when the customer gives an instruction. ) The IP telephone number of 5 may be taken out of the content and the IP telephone terminal (operator) 5 may be called. When the customer looks at the advertisement information and likes “Aurora Encounter and Baltic Sea Cruise 8 Days” 83, 85, and wants to apply or make an inquiry, the IP phone terminal (customer) 3 sends an IP phone terminal ( Call the operator 5). In addition, an input interface (GUI) such as a slide show 87, a luxury cruise menu 91, and a main menu 93 is provided.

  Here, when the “application for this tour” button 95 displayed (81) on the screen display unit 31 of the IP telephone terminal (customer) 3 is touched, the IP telephone terminal (operator) 5 is called.

  FIG. 5 is a diagram showing a display screen example 100 when the IP telephone terminal (customer) 3 is connected to the IP telephone terminal (operator) 5 of the travel agency. The display screen 100 includes a general information display unit 103, a personal information display unit 101, and a partner image display unit 105. The general information display unit 103 is a part for displaying information provided in common to all customers among the contents provided from the IP telephone terminal (customer) 3. For example, a travel company name, detailed tour information, and the like are displayed. The The personal information display unit 101 is a part that displays information provided only to a customer who is on the phone among the contents provided from the IP telephone terminal (customer) 3. For example, the name, address, and telephone number of the customer , Credit card number etc. are displayed.

  Further, the partner image display unit 105 uses the IP terminal (operator) 5 to display an image of the operator who is dealing with the customer by telephone. In the case of an IP-TV phone terminal, a moving image may be displayed, and in the case of an IP phone with only voice, the partner image display unit 105 may display a still image created and stored in advance. The partner image display unit 105 is an option. The content displayed on the general information display unit 103 and the content displayed on the personal information display unit 101 are transmitted via an IP telephone system session established between the IP telephone terminal (customer) 3 and the IP telephone terminal (operator) 5. Then, the content URL is passed from the IP telephone terminal (operator) 5 to the IP telephone terminal (customer) 3, and the content is acquired based on the URL received by the IP telephone terminal (customer) 3.

  Note that at least the content displayed on the personal information display unit 101 needs to be stored in the temporary Web server 11 according to the present embodiment. The content displayed on the general information display unit 103 may be stored in the temporary Web server 11 or may be stored in a Web server other than the temporary Web server 11. Moreover, the information displayed on the general information display unit 103 and the information displayed on the personal information display unit 101 may be configured as one content. However, in that case, content configured as one content is stored in the temporary Web server 11. The reason is that the personal information needs to be stored in the temporary Web server 11, but the personal information is included in the content when the content is composed of one content.

  When a telephone call is made from the IP telephone terminal (customer) 3 to the IP telephone terminal (operator) 5, an IP telephone system session for a videophone call is made between the IP telephone terminal (customer) 3 and the IP telephone terminal (operator) 5. And the URL of the content displayed on the personal information display unit 101 and the content displayed on the general information display unit 103 from the IP telephone terminal (operator) 5 to the IP telephone terminal (customer) 3 through the session. The URL is passed, and the IP telephone terminal (customer) 3 acquires the content based on the URL, and configures the screen 100 shown in FIG. It is assumed that nothing is written in the “name”, “address”, “phone number”, and “credit card number” fields immediately after the start of the call.

  FIG. 6 shows that in the IP telephone terminal (customer) 3, the personal information of the customer of the IP telephone terminal (customer) 3 entered by the operator in the IP telephone terminal (operator) 5 of the travel agency is the IP telephone terminal (customer). It is the display screen example 100 which shows having been reflected on the display screen. When a customer applies for a tour, personal information such as “name”, “address”, “phone number”, and “(credit) card number” needs to be taught to the operator of the travel agency. For example, when teaching personal information to an operator using a voice telephone, the operator who heard the personal information transcribes the customer's personal information into an application document, or enters the customer's personal information into a travel agency database. When doing this, you may end up transferring / entering incorrectly. Therefore, it is important to provide feedback to the customer on how the operator has transcribed / input. In the present embodiment, a customer on the IP telephone terminal (customer) 3 side makes a videophone call with his / her name, address, telephone number, credit card number, etc. by voice without using an input device such as a keyboard, mouse, or remote control. It is possible to confirm whether or not the operator has surely input his / her name, address, telephone number and credit card number by looking at the personal information display unit 111 simply by telling the other operator.

  FIG. 11 is a diagram showing a Web page creation screen example 230 of the IP telephone terminal (operator) 5. The window 231 is a screen for making a reservation according to the schedule of the customer, and the window 233 is a screen on which the customer's personal information is displayed. An operator who operates the IP telephone terminal (operator) 5 knows personal information such as the customer's own name, address, telephone number, and credit card number transmitted by the customer's voice via the IP telephone. The customer's personal information is input to each item in this window. It is also possible to confirm the reservation status at any time with the reservation status confirmation button 235.

  When the input is completed, the operator clicks “information sharing” 237 to perform information sharing processing. Then, the personal information window 230 is converted into a Web page by the Web page generation unit 61.

  FIG. 7 is a flowchart showing the flow of control processing in the temporary Web server control unit 63 of the IP telephone terminal (operator) 5. File sharing is started in step S1, personal information is uploaded to the temporary Web server 11 in step S2, and the URL of this personal information is notified to the IP telephone terminal (customer side) 3 in step S3.

Subsequent processing will be described later.
The IP telephone terminal (customer) 3 acquires content including personal information placed on the temporary Web server 11 and updates the display of the personal information display unit 101. As a result, the contents entered by the operator are fed back to the IP telephone terminal (customer) 3 so that the customer can know how the operator has entered the personal information and can complete the travel application with peace of mind. .

  The timing when the personal information is uploaded from the IP telephone terminal (operator) 5 to the temporary Web server 11 is “name”, “address”, “phone number”, “credit card number” as in the present embodiment. It may be after all items of personal information are input, every time one item is filled, or depending on the case, every time an operator inputs one character. When the operator inputs feedback to the customer's IP phone terminal (customer) 3 every time a character is input, it feels as if the operator is directly operating the IP phone terminal (customer) 3 in front of herself. be able to.

  FIG. 8 is a flowchart showing the flow of processing in the temporary Web server control unit 33 of the IP telephone terminal (customer) 3. The file sharing process is started (step S11). When a URL is received from the IP telephone terminal (operator) 5 in step S12, file download is started in step S13.

  At this time, eavesdropping by a third party can be prevented by establishing a secure session such as HTTPS. Further, in order to prevent spoofing by a third party, only a specific customer terminal may access the page by sending a password necessary for accessing the temporary Web server 11 together with the address. Further, if this password is a one-time password, it is possible to prevent a sneak view by a customer who has previously accessed the same URL.

  If the IP call is disconnected before the download is completed in step S14 (Y), the process proceeds to step S19, where the download is stopped. If the IP call is ongoing (N), it is determined whether or not there is a download error in step S15. If it is an error (Y), the process proceeds to step S16 to determine whether or not to retry, and retry is performed. In the case (Y), the process returns to step S14. When not retrying (N), the process proceeds to step S19. In step S17, it is determined whether or not the download is completed. If not completed (N), the process returns to step S14. If completed (Y), the IP telephone terminal (operator) 5 is notified in step S18 that the download has been completed, and the process is terminated (step S20).

  The notification means from the IP telephone terminal (operator) 5 to the IP telephone terminal (customer) 3 and from the IP telephone terminal (customer) 3 to the IP telephone terminal (operator) 5 uses the command function of the IP telephone. These commands are usually exchanged within a secure session to prevent eavesdropping. Other methods, for example, if the IP telephone terminal has a mail function or a short message function, may be notified using those functions.

  Upon receiving the download completion notification from the IP telephone terminal (customer) 3 (FIG. 7, step S6), the IP telephone terminal (operator) 5 immediately deletes the content on the temporary Web server 11 (step S7). Complete the process.

  Alternatively, as soon as the call between the IP telephone terminal (customer) 3 and the IP telephone terminal (operator) 5 ends (step S4), the content is deleted (step S7). Further, after a network error or the like occurs and the IP telephone terminal (operator) 5 uploads the content, the IP telephone terminal (customer) 3 does not acquire the content or cannot confirm that the content has been acquired (step S5). Even in this case, the content is deleted (step S7).

  If the above-described exchange is repeated and the customer is satisfied, the web page created on the IP telephone terminal (operator) 5 is transferred to an order processing server (not shown) by the operator or the ordering operation by the customer, and the order processing is performed thereafter. . Here, when the customer touches the “apply” button (FIG. 6: 119) displayed on the screen of the IP telephone terminal (customer) 3, the ordering process is performed.

  In the present embodiment, the order processing server is a secure server that is not directly visible to the customer side, and there is little risk of eavesdropping from the outside even if stored for a long time. However, in order to confirm later, an ID or password may be issued to the customer, and the order information may be viewed by inputting it.

  Further, the Web page on the IP telephone terminal (customer) 3 may be stored in the storage unit 27 or deleted after leaving a history of information in some form, for example, outputting paper by a printer connected to the network. Good.

  As described above, according to the present embodiment, the risk of leakage of personal information such as eavesdropping is minimized by minimizing the period in which content including customer personal information exists on the temporary Web server. There is an advantage that it can be suppressed to the limit.

  Next, a second embodiment of the present invention will be described. In the first embodiment, the call is between two parties. However, the present embodiment relates to a case where a plurality of calls are made between three parties.

  FIG. 12 is a diagram illustrating a configuration example of a system according to the present embodiment. In the present embodiment, an IP telephone session is established between three parties: an IP telephone terminal (operator) 245, an IP telephone terminal (customer A) 241, and an IP telephone terminal (customer B) 243. The external appearance of the IP telephone terminal (operator) 245 and the functional blocks and external appearances of the IP telephone terminals (customers) 241 and 243 may be the same as those in the first embodiment.

  FIG. 13 is a diagram showing a display screen example 260 by the Web page generation unit of the IP telephone terminal (operator) 245 according to the present embodiment. The common window 261 is a screen for editing travel schedule information common to two customers, the individual information window 263 is personal information of the customer A, and the individual information window 265 is personal information of the customer B. The window surrounded by the bold line (here, 263) is currently selected for editing.

  In the first embodiment, the customer conveys all personal information by voice and the operator inputs it. In the present embodiment, since a call between three parties is performed, only a card number is input by a customer operating a key button of an IP telephone terminal (customer), for example. In this state, when the operator clicks the “all sharing” button 271 or the “individual sharing” button 273, information sharing is started. The web page generation unit generates a web page in which individual information corresponding to common information is merged for each customer.

  FIG. 14 is a flowchart showing the flow of processing when all sharing is performed in the temporary Web server control unit of the IP telephone terminal (operator side) 245. The description will be made with reference to FIGS.

  When all sharing processing step S31 is started, the individual web pages 247a, 247b,... Created by the web page generation unit in step S32 are uploaded to the temporary web server 247, respectively. In step S33, it is determined whether or not the data of all customers in the call have been uploaded. If Y, the process proceeds to step S34 to notify each customer of the URL of each individual page. In step S35, it is determined whether or not all customers in the call have been notified. If YES, the process proceeds to step S36, where the IP call is terminated, whether a certain time has passed in step S37, or download is completed in step S38. It is determined whether a notification has been received. Regarding the deletion of data, the customer's Web page corresponding to when the download completion notification is received for each customer is deleted (step S39). When the IP call ends during downloading or when a certain time has elapsed, all the customer-specific web pages remaining on the temporary web server 247 are deleted (step S40). The process ends (step S42).

  Note that in the case where information sharing is performed only for a customer selected by a bold line, it can be shared by the same processing as in the first embodiment.

  FIG. 15 is a diagram illustrating a display example 300 of the screen display unit when information is shared in the IP telephone terminal (customer A) 5. The common information is displayed in the window 302, and only the personal information of the customer A is displayed in the window 301. The window 305 displays an operator, the window 307 displays a customer, and a return button 311 and an application button 315 are provided.

  By the same operation as described above, it is possible to acquire personal information and add a personal information identifier. As a result, it is possible for a plurality of people to collectively apply at the time of application, and to individually perform the authentication.

  As described above, personal information can be safely shared even when three or more parties make a call, and impersonation of a third party can be prevented.

  As described in detail above, according to each embodiment of the present invention, information can be shared more safely during an IP telephone call. Therefore, the customer can receive Web shopping and Web services easily and safely.

  Since protocol processing such as the temporary Web server control function of the IP telephone terminal (customer) is implemented by software / firmware, the terminal can be manufactured without increasing costs. If software and firmware can be updated, existing devices can be used.

  Further, there is an advantage that the temporary Web server can be realized with an existing one without constructing a special server.

  The present invention can be used for services using IP terminals.
