Description

  The present invention relates to a communication system and a communication method for realizing a two-party call or a multi-party call by third party control.

  In recent years, a technique called 3rd party call control (3PCC) that enables terminals to connect to each other and make a call with a single click on an address book displayed on a personal computer screen has become widespread (for example, Patent Document 1). ). By using 3PCC technology, terminals can be connected to each other with a single click, so that business efficiency can be realized. In addition, central management of telephone numbers in a corporate telephone directory also helps protect personal information. In addition, a teleconference system with high operability using the Web, in which a multi-party call function using 3PCC technology is implemented, has been developed.

FIG. 15 is a conceptual diagram of a communication system that realizes a two-party call using 3PCC technology.
By clicking a partner on the address book displayed on the screen of the user's personal computer 1 that issues a connection instruction, a connection instruction (1) is issued to the third party control system 3 via the Internet or the intranet 2. The third party control system 3 connects to the telephone terminal 4 designated in advance by the user (2), and confirms that the user has responded at the telephone terminal 4, and then connects to the telephone terminal 5 of the other party and calls (3) When the telephone terminal 5 responds, the terminals are connected to make a call possible state (4).

Alternatively, the call may be made by connecting to the other party's telephone terminal 5 first, and if the telephone terminal 5 responds, the connection to the user's call terminal 4 is made, and if the user off-hooks the call terminal 4, the terminals may be in a call-ready state. it can. In the case of the teleconference system, the third party control system is called by sequentially clicking the partner who is scheduled to participate in the conference on the address book displayed on the screen of the user's (calling side) personal computer 1. 3 adds the other terminal that has been off-hook or responded to the call being established in order, so that a multi-party call is possible.

  However, since the conventional system using the 3PCC technology cannot be canceled before the call is established, there are the following problems.

  (1) Since there is no means for disconnecting a call without receiving the other party's phone, there is a problem that the other party's phone is ringed or the user's telephone number is left in the incoming call history. In the conventional method of making a call by dial or button operation, if you reconsider making a call while performing the dial operation or button operation of the phone, or if you notice a mistake in the phone number and cancel the call, It was possible to cancel without calling. However, when the 3PCC technology is used, when the user's own phone rings and responds, the other party starts to be called, so there is no way to cancel before calling the other party. The other party could cause inconvenience such as "The call was disconnected despite trying to answer the call", or "The call was returned by looking at the incoming call history".

  (2) When calling the other party before the user, this connection cannot be canceled unless a call between the other party and the user is established. If the other party does not answer, the other party's phone will continue to ring. It will cause trouble. In addition, there is a problem that if the wrong party is called, the other party is forced to answer the call.

  (3) There is a problem in that when a callee terminal automatically answers, the user is forced to communicate with an automatic answering device such as an answering machine at the other terminal. Even if the person who called using 3PCC technology or the other party is in a state where a call cannot be made, such as an answering machine function, the next process is to call the other party or own seat. Will go. In such a case, when the called party answers the call, the other party's answering machine message will be heard. In the case of a conference phone, there is a problem that a message on the answering machine flows to the conference participant and the voice of the conference participant is recorded on the answering machine for a certain period of time.

  The present invention has been made in view of the above circumstances, and is a two-party call or a multi-party call using the 3PCC technology, and the connection of a terminal designated and connected by a third party is established before the call is established or It is an object of the present invention to provide a communication system and a communication method that can be canceled later and do not cause trouble to the other party or the user.

  The communication system of the present invention receives a connection request specifying a connection destination terminal at a user apparatus, notifies the connection instruction from the user apparatus to a third party control apparatus, and the third party control apparatus transmits the connection instruction. A communication system that calls a user terminal and a partner terminal in response to the connection and connects the user terminal and the partner terminal to enable a two-party call or a multi-party call, wherein the user device is currently connected A terminal display means for displaying a terminal designated by the terminal, a terminal selection means for selecting a terminal selected by the user among the terminals displayed on the terminal display means as a cancel terminal, and a terminal selection means selected by the terminal selection means Canceling means for sending a cancel instruction to call or terminate the terminal from the talking state to the third party control device is provided.

  According to the communication system configured as described above, when the user selects a terminal whose connection is to be canceled from among the currently displayed connection terminals, a cancel instruction for calling the selected terminal or releasing the call state from the call state is issued. It can be sent to a third party control device and released from the call or call.

  Further, the communication system of the present invention receives a connection request designating a connection destination terminal at a user device, notifies a connection instruction from the user device to a third party control device, and the third party control device receives the connection. A communication system that calls a user terminal and a partner terminal in response to an instruction and connects the user terminal and the partner terminal to enable a two-party call or a multi-party call, wherein the user device is used Wait for a certain period of time after receiving a connection request from the user until notification of the connection instruction to the third party control device, and if a cancel instruction is input from the user during the waiting time, connect to the third party control device An instruction is not notified.

  As a result, there is a waiting time for a certain time until the third party control device is notified of the connection instruction, so reconsidering making a call during this waiting time, and if you notice an error in the phone number, cancel the instruction. Can be canceled without calling the other party.

  Further, the communication system of the present invention receives a connection request designating a connection destination terminal at a user device, notifies a connection instruction from the user device to a third party control device, and the third party control device receives the connection. A communication system that calls a user terminal and a partner terminal in response to an instruction and connects the user terminal and the partner terminal to enable a two-party call or a multi-party call, wherein the third-party control device includes: , Wait for a certain period of time after receiving a connection instruction from the user device until calling the user terminal or the partner terminal, and if a cancel instruction is input from the user during the waiting time, the user terminal or partner terminal The connection instruction is canceled without calling.

  As a result, it will wait for a certain period of time after receiving a connection instruction from the user device until it starts calling the terminal, so if you reconsidered making a call during this waiting time and noticed an error in the phone number In this case, it is possible to cancel without calling the terminal by inputting a cancel instruction from the user device.

  Further, the communication system of the present invention receives a connection request designating a connection destination terminal at a user device, notifies a connection instruction from the user device to a third party control device, and the third party control device receives the connection. A communication system that calls a user terminal and a partner terminal in response to an instruction and connects the user terminal and the partner terminal to enable a two-party call or a multi-party call, wherein the third-party control device includes: When calling a user terminal or a partner terminal based on a connection instruction received from the user device, and calling the partner terminal or the user terminal after a lapse of a certain time after a response from the user terminal or the partner terminal, the user terminal Alternatively, the connection is stopped when the user terminal or the partner terminal is on-hooked within a certain time after the response of the partner terminal.

  As a result, the connection is canceled when the user terminal is on-hooked within a certain time after the response of the user terminal, so the user can simply on-hook the user terminal within a certain time after the response of the user terminal. Connection instructions can be canceled without calling the other terminal.

  Further, the communication system of the present invention receives a connection request designating a connection destination terminal at a user device, notifies a connection instruction from the user device to a third party control device, and the third party control device receives the connection. A communication system that calls a user terminal and a partner terminal in response to an instruction and connects the user terminal and the partner terminal to enable a two-party call or a multi-party call, wherein the third-party control device includes: The user terminal is called based on the connection instruction received from the user device, and the connection is stopped when the user terminal does not respond within a certain time from the start of the call.

  As a result, the connection is canceled if the user terminal does not respond within a certain time from the start of the call, so if the user wants to cancel the connection instruction after sending the connection instruction, the user terminal will answer the call to the user terminal. The connection instruction can be canceled without calling the partner terminal.

  Further, the communication system of the present invention receives a connection request designating a connection destination terminal at a user device, notifies a connection instruction from the user device to a third party control device, and the third party control device receives the connection.

Thus, when the user selects a terminal to cancel the connection from among the displayed connection terminals, a cancel instruction to call the selected terminal or release from the call state is sent to the third party control device. Can be freed from calls or calls.

  According to the present invention, it is possible to cancel the connection of a terminal specified and connected from a third party while the call is a two-party call or a multi-party call using 3PCC technology, before the call is established. It is possible to provide a communication system that does not cause trouble.

  A telephone service communication system according to an embodiment of the present invention will be specifically described below with reference to the drawings.

(First embodiment)
FIG. 1 is a conceptual diagram of a communication system that realizes a two-party call or a multi-party call by third party control according to the present embodiment. The connection terminal inquiry screen M1 is displayed on the user personal computer 10 so that a terminal for canceling the connection instruction can be designated. A connection terminal inquiry screen M1 displaying a list of all counterpart terminals for which connection instructions have been issued to the third party control system 11 at this stage can be called to the user personal computer 10. The connection terminal inquiry screen M1 is provided with a cancel button 12 for each connection terminal, and when the cancel button 12 is clicked, a disconnection request for the corresponding connection terminal is transmitted to the third party control system 11. The terminal whose connection instruction has been canceled and the terminal whose connection has been disconnected are deleted from the connection terminal inquiry screen M1, and the screen transitions to the connection terminal inquiry screen M2.

  FIG. 2 shows functional blocks of a part related to a two-party call or a multi-party call under the third party control in the user personal computer 10. The user personal computer 10 receives user operation input via the user interface 21 and displays and outputs information. The connection instruction unit 22 is an application that provides a screen necessary when a user issues a connection instruction to the third party control system 11 from the screen of the user personal computer 10. In the case of a configuration in which a user's telephone number is input on a Web screen and a connection is made to a predetermined company, it can be configured by browser software. The connection cancel unit 23 inquires of the connection instruction unit 22 about a terminal for which a connection instruction has been issued, and presents a connection terminal inquiry screen to the user. The connection instruction cancels and connects on the connection terminal inquiry screen M1. A cancel terminal selection unit 25 that accepts disconnection of the terminal, and a cancel instruction unit 26 that is instructed to cancel the connection instruction or to disconnect, and notify the third party control system 11 of the cancel instruction for the terminal. The interface provided by the connection cancel unit 23 can be used by specifying a specific URL with a Web browser. Alternatively, a dedicated application screen for the browser may be used instead of the Web screen, and the interface is installed by installing an application that runs on the personal computer instead of the browser and starting it as necessary. May be provided.

  The system configuration illustrated in FIG. 2 is an example in which the user interface 21, the connection instruction unit 22, and the connection cancellation unit 23 are provided on the user side, but can be variously changed depending on the application. For example, a system configuration in which only the user interface 21 is placed on the user side is possible, and the connection instruction unit 22, the connection cancellation unit 23, and the third party control system 11 may be housed in the same housing.

Next, the operation of the present embodiment configured as described above will be described.
As shown in FIG. 1, a user inputs a connection request specifying a connection destination terminal using a user personal computer 10 serving as a user device. In the present embodiment, the terminal B is selected by selecting from the address book displayed on the user personal computer 10 or by directly inputting a telephone number, and a connection instruction is issued. The third party control system 11 receives a connection instruction from the user personal computer 10, first calls the user terminal A, receives a response from the terminal A, calls the terminal B, and receives a response from the terminal B to receive the terminal A and terminal B are connected. Further, a connection instruction for the terminal C is issued from the user personal computer 10, and the third party control system 11 calls the terminal C, receives a response from the terminal C, and participates in a call between the terminal A and the terminal B.

  The cancellation of the connection instruction issued from the user personal computer 10 to the third party control system 11 can be performed on the Web screen displayed on the user personal computer 10. The terminal inquiry unit 24 receives an operation input from a user via the user interface 21. When a connection terminal inquiry request is input, the terminal inquiry unit 24 acquires terminal information that is currently issuing a connection instruction from the connection instruction unit 22, and displays a connection terminal inquiry screen M1 illustrated in FIG. The connection terminal inquiry screen M1 is provided with a cancel button 12 for canceling a connection instruction for the connection terminal. The user clicks the cancel button 12 of the terminal for which the connection instruction is to be sent. The cancel terminal selection unit 25 receives the click of the cancel button 12 and recognizes the corresponding terminal. The cancel instruction unit 26 transmits to the third party control system 11 the connection terminal information that has received the cancel request on the connection terminal inquiry screen M1. The third party control system 11 recognizes the cancellation target terminal C indicated in the connection terminal information received from the cancellation instruction unit 26 and disconnects the connection with the cancellation target terminal C. On the other hand, the connection instruction unit 22 receives the cancel request issued by the cancel instruction unit 26 and excludes the corresponding terminal from the connection terminals. The terminal inquiry unit 24 that has received the information of the terminal for which the connection instruction has been issued from the connection instruction unit 22 deletes the terminal requested to cancel from the connection terminal inquiry screen M1, and transitions to the connection terminal inquiry screen M2. For example, if the user notices the wrong partner selection immediately after sending out the connection instruction, the third party control system 11 can be requested to cancel by displaying the connection terminal inquiry screen M1 and clicking the cancel button 12 of the corresponding terminal. Can be communicated.

  FIG. 3 is a flowchart showing the operation contents of the third party control system 11. The third party control system 11 receives a connection instruction from the user terminal 10 (step S1) and calls the user terminal A (step S2). When it is detected that the user has responded at the terminal A at the seat (step S3), the counterpart terminal B is called (step S4). When it is detected that the terminal B has responded (step S5), the terminal A and the terminal B are connected to establish a call (step S6).

  For example, while the third party control system 11 is calling the user terminal A (step S2), the user displays the connection terminal inquiry screen M1 on the user personal computer 10 and presses the cancel button 12 of the terminal B. click. As a result, a cancel request for canceling the connection instruction of the terminal B is sent to the third party control system 11.

  When the third party control system 11 receives the cancel request for the terminal B (step S7), the third party control system 11 cancels the connection instruction before calling the terminal B (step S8). Accordingly, the user can interrupt the call to the terminal B before receiving the call to the terminal B by clicking the cancel button 12 of the terminal B on the connection terminal inquiry screen M1 while calling the terminal A at his / her seat.

  Also, after responding at the user terminal A (step S3), the calling of the partner terminal B is automatically started (step S4), but before the terminal B responds, the user connects to the user personal computer 10 When the inquiry screen M1 is displayed and the cancel button 12 of the terminal B is clicked, the cancel request is received (step S9), the call to the terminal B is interrupted and the connection to the terminal B is disconnected before the call is established. Yes (step S8).

  Further, it is assumed that the call between the terminal A and the terminal B is established by the terminal B responding in step S5. When the terminal B is set as an answering machine, it is connected to the answering machine function and an answering message is played. Even at this time, the third party control system 11 receives the cancel request by displaying the connection terminal inquiry screen M1 on the user personal computer 10 and clicking the cancel button 12 of the terminal B (step S10). Can only be cut.

  As described above, according to the present embodiment, the connection instruction can be canceled from the connection terminal inquiry screen M1 displayed on the user personal computer 10, so that the partner terminal B is connected before the user terminal A responds. If canceled, it can be canceled before calling the partner terminal B, and it is possible to prevent the other party from being troubled. Further, since all the connected terminals are displayed on the connected terminal inquiry screen M1, and the connection instruction of an arbitrary terminal can be canceled therefrom, the terminal connected to the answering machine function can be quickly disconnected.

FIG. 9 to FIG. 11 show configuration examples of the connection terminal inquiry screen.
FIG. 9A is a diagram showing a connection terminal inquiry screen M1 when a multi-party call is performed under the third party control. A user terminal (telephone number = AAAAAAA), a second terminal (telephone number = BBBBBB), and a third terminal (telephone number = CCCCCC) are performing multi-party calls. On the connection terminal inquiry screen M1 of the user terminal, the telephone number 61 of the currently connected terminal is displayed in order, and a cancel button 62 is displayed corresponding to the telephone number. As shown in FIG. 9B, when canceling the connection with the terminal having the telephone number = BBBBBBB, the cancel button 62a corresponding to the telephone number = BBBBBBB is selected.

  10 (a) and 10 (b) are examples in which a screen for instructing release is configured by using the screen (transmission instruction screen) used when instructing transmission. FIG. 10A shows a screen in which the user terminal (phone number = AAAAAAA) selects the terminal (phone number = BBBBBBB) and the terminal (phone number = CCCCCC) as the other party and instructs the call. As the instruction button 63, a connection button 64 for selecting and instructing a connection terminal and a release button 65 for instructing connection release are provided separately. When designating multiple terminals at once, a conference button may be prepared so that instructions can be issued at a time. As shown in FIG. 10B, when disconnecting from the terminal (phone number = BBBBBB), the release button 65a of the terminal (phone number = BBBBBB) is selected.

  FIGS. 10C and 10D are examples of the screen configuration of the release instruction using the call instruction screen as it is, but are examples in which the connection button and the release button are not provided separately. FIG. 10C shows a screen in which the user terminal (telephone number = AAAAAAA) selects the terminal (telephone number = BBBBBBB) and the terminal (telephone number = CCCCCC) as the other party, and instructs the transmission. A dual-purpose button 66 serving as both a connection button and a release button is displayed. In the outgoing instruction screen, the dual-purpose button 66 functions as a connection button. As shown in FIG. 10 (d), when disconnecting from the terminal (phone number = BBBBBB), the dual-purpose button 66a of the terminal (phone number = BBBBBB) is selected. In the release instruction screen shown in FIG. 10D, the shared button 66a functions as a release button.

  FIGS. 11A and 11B are screen configuration examples in which a release button is displayed on a terminal that can be canceled (already connected) on a screen for instructing outgoing calls. FIG. 11A shows a screen in which the user terminal (telephone number = AAAAAAA) selects the terminal (telephone number = BBBBBBB) and the terminal (telephone number = CCCCCC) as the other party and directs the call. When a user terminal (phone number = AAAAAAA), a terminal (phone number = BBBBBB), and a terminal (phone number = CCCCCC) are connected, the screen changes to the screen shown in FIG. Is displayed and a cancel instruction screen is displayed. It is conceivable that a release button is newly generated and displayed every time transmission is selected, or a release button is displayed using a bookmarklet technique.

  FIGS. 11 (c) and 11 (d) are screen configurations for displaying a release button on a terminal that can be canceled (already connected) on a screen for instructing outgoing calls. This is an example of a connection button. FIG. 11C shows a screen in which the user terminal (telephone number = AAAAAAA) selects the terminal (telephone number = BBBBBBB) and the terminal (telephone number = CCCCCC) as the other party and directs the call. The terminal (phone number = DDDDDD) is not selected as the other party. As shown in FIG. 11D, a release button is prepared for the terminal (telephone number = BBBBBB) and the terminal (telephone number = CCCCCC) selected as the other party.

  In the above description, the button is used, but a link, a check box, or the like can be used instead of the button.

(Second Embodiment)
In the second embodiment, the connection operation of the user terminal or the partner terminal is started after waiting for a certain time after the connection instruction by the third party control. A communication system for realizing a two-party call or a multi-party call by third party control is the same as the communication system shown in FIG.

  FIG. 4 is a flowchart for issuing an actual connection instruction to the third party control system 11 after a predetermined time has elapsed from the user's connection instruction in the user personal computer 10. When the connection instruction unit 22 is activated in the user personal computer 10, it is determined whether a connection instruction has been input by selecting a partner terminal (step S20). If a connection instruction is input, the apparatus enters a standby state until a predetermined time T1 elapses after the connection instruction is input (step S21). During a period from when the connection instruction is input until the predetermined time T1 elapses, it is monitored whether or not the connection instruction is canceled (step S22). Even after the user selects the terminal B and issues a connection instruction, the user can cancel the actual calling operation itself if the user instructs cancellation before the predetermined time T1 elapses. The cancel method can use the cancel button 12 on the connection terminal inquiry screen M1 as in the first embodiment. If the connection instruction is canceled before the predetermined time T1 elapses after the connection instruction is input (step S22), the process ends without performing the calling operation on the counterpart terminal B (step S23). For example, even if it is set to call the terminal B of the connection partner for the first time, the connection instruction is sent from the user personal computer 10 to the third party control system 11 if a predetermined time T1 has elapsed after the connection instruction is input. Since the connection instruction is not transmitted, the connection operation can be terminated without calling terminal B.

  On the other hand, when a predetermined time T1 elapses after the connection instruction is input, a connection operation similar to that in the first embodiment is started (step S24). A connection instruction is transmitted from the user personal computer 10 to the third party control system 11. Even after the start of the connection operation, the connection with the terminal can be disconnected using the cancel button 12 on the connection terminal inquiry screen M1 as in the first embodiment.

  In this way, the connection operation is not started immediately after the connection is specified by the third party control, but the connection instruction is canceled before actually calling by actually entering the connection after waiting for a certain period of time. Can prevent the other party from being inconvenienced.

  FIG. 5 is a flowchart for issuing a connection instruction to the terminal after a predetermined time has elapsed since the connection instruction from the user was received in the third party control system 11. When the third party control system 11 receives the connection instruction from the user personal computer 10 (step S30), the third party control system 11 starts measuring the elapsed time with a timer and does not make a call until the standby time T2 elapses (step S31). If a cancel instruction is received from the user personal computer 10 during this waiting time T2 (step S32), the connection instruction received in step S30 is canceled (step S33). When the connection instruction is canceled, the process ends without making a call to the user terminal A and the partner terminal B.

  On the other hand, in the determination in step S31, it is confirmed that no cancellation is received even when the standby time has elapsed, and the terminal is called. In the example shown in FIG. 5, the user terminal A is called first (step S34), and when the user responds with the terminal A at his seat (step S35), the partner terminal B is called (step S36). When the counterpart terminal B responds (step S37), the user terminal A and the counterpart terminal B are connected to establish a call (step S38).

  In this way, even if the third party control system 11 issues a connection instruction to the terminal after a lapse of a certain time after receiving the connection instruction from the user, the user who notices the error immediately after issuing the connection instruction immediately If the cancel operation is performed, the actual call operation can be prevented.

  In the first and second embodiments described above, the application for realizing the connection cancel unit 23 is installed in the user personal computer 10 and the connection terminal inquiry screen is presented. However, such an interface is prepared. Even if it is not, it is possible to notify the third party control system 11 of the cancel instruction. For example, a second operation may be recognized as a cancel operation by repeatedly performing an operation of inputting a connection instruction via the connection instruction unit 22. When the third party control system 11 receives the first connection instruction and calls the user terminal A or the partner terminal B, if the second connection instruction is received, it is recognized as a cancel instruction for the connection instruction. Interrupt the call.

(Third embodiment)
In the third embodiment, after a connection instruction is issued from the user personal computer 10 to the third party control system 11, a cancellation is performed using the user terminal. The terminal A of the user's own seat is called, and when the user answers at the terminal A, the other terminal is not called immediately, but is called after waiting for a certain time.

  FIG. 6 is a flowchart for calling the partner terminal after a lapse of a certain time from the response of the user terminal A in the third party control system 11. Assume that the user terminal 10 is selected from the user personal computer 10 and a connection instruction is issued. When receiving the connection instruction (step S40), the third party control system 11 calls the user terminal A (step S41). When there is a response from the user terminal A (step S42), the call to the partner terminal B is not performed until a predetermined time T3 has passed (step S43). Since the calling of the partner terminal B is not performed for a certain time T3 from the response of the user terminal A, if a cancel instruction is input from the user personal computer 10 during that time, the connection may be interrupted before the partner terminal B is called. it can. When the third party control system 11 receives a cancel instruction from the response of the user terminal A before a predetermined time T3 has elapsed (step S44), the third party control system 11 cancels the connection instruction for the terminal B (step S45). Therefore, the user can cancel the connection without calling the partner terminal B if a cancel instruction is issued before the fixed time T3 elapses after the terminal A responds to the call. Alternatively, if the on-hook of the terminal A is set to be recognized as cancelled, the user can cancel before calling the other party by on-hooking immediately after answering and disconnecting the telephone.

  When a certain time T3 has elapsed without receiving a cancel instruction after the user terminal A responds, the calling of the partner terminal B is started (step S46). If partner terminal B responds to the call (step S47), terminal A and terminal B are connected to establish a call (step S48).

  As described above, when the user responds with the terminal A and calls the partner terminal B after a predetermined time T3 has elapsed, the user can cancel before calling the partner because there is room for cancellation.

  In addition, even if the user issues a connection instruction and the telephone at his / her seat is called, the user may recognize that the call has been canceled if there is no response for a certain period of time. FIG. 7 is a flowchart for canceling processing when a user does not respond for a certain time even when the user's own telephone is called. The same steps as those in the flowchart shown in FIG. The third party control system 11 recognizes that the connection instruction is cancelled and stops the connection when there is no response even after a predetermined time T4 has elapsed since the start of calling the user terminal A (step S49). . The fixed time T4 needs to be set to a time shorter than the time when the terminal A automatically responds.

(Fourth embodiment)
The fourth embodiment is an example in which a call is not established for a terminal that is connected to the answering machine function and cannot talk. A communication system for realizing a two-party call or a multi-party call by third party control is the same as the communication system shown in FIG.

  FIG. 8 is a flowchart in the third party control system 11 in the present embodiment. When a connection instruction is received from the user personal computer 10 (step S50), the user terminal A is called (step S51). When there is a response from the user terminal A (step S52), an announcement is given to perform a predetermined button operation (step S53). For example, when the user's terminal A is set to answering machine, the conventional automatic answering is performed. However, in the present embodiment, unless the user performs a button operation on the terminal A, the following is performed. No terminal calls are made. If the user has mistakenly set the answering machine for terminal A, the requested predetermined button operation is not performed, and a connection cancellation process is performed (step S55).

  When the user performs a predetermined button operation according to the announcement (step S54), the calling of the partner terminal B is started (step S56). When partner terminal B responds (step S57), an announcement is sent to perform a predetermined button operation in the same manner as described above (step S58). When the partner terminal B is set to answering machine and the partner is absent, the button operation corresponding to the announcement is not performed. The third party control system 11 determines whether or not a predetermined button operation has been performed from the partner terminal B that has responded (step S59). If the requested button operation has not been performed, a connection cancellation process is performed (step S59). S55). Therefore, when the partner terminal B is connected to the answering machine function and automatically answers, the connection cancellation process is performed without establishing the call.

  When a button operation corresponding to the announcement is performed at the partner terminal B (step S59), a call between the user terminal A and the partner terminal B is established (step S60).

  As described above, since the connection is made only when a predetermined button operation is performed from the terminal that responds to the call, when the answering machine function automatically answers, the connection is canceled without establishing the call. be able to.

  In the above description, the button operation is announced to the terminal that responds to the call. However, the third party control system 11 recognizes the button operation in advance so that a predetermined button operation is performed. If you can, you don't have to make announcements. Further, in the flowchart shown in FIG. 8, the button operation announcement is sent to both the user terminal and the counterpart terminal, but the announcement may be sent to only one side. For example, when a button operation from the counterpart terminal is not expected, an operation announcement is sent only to the user terminal.

(Fifth embodiment)
The fifth embodiment has the same system configuration as that of the fourth embodiment, and establishes the two-party call after the user gives a connection permission prior to the two-party call under the control of the third party. This is an example.

  Currently, there is a service that allows a user to input a telephone number of a telephone he / she wants to use and to connect to a specific partner (a business operator who wants to receive calls from an unspecified number of users). As shown in FIG. 16, when a web screen 70 is displayed on the user personal computer 10 by accessing a service site 73 on the Internet, a telephone number input box 71 is displayed together with a message “Please enter your telephone number”. Is displayed. When the telephone number (03-AAA-BBB) of the telephone that the user wants to use is entered in the input box 71 and the call button 72 is clicked, a connection instruction is transmitted to the third party control system 11 and the telephone designated by the user. The number (03-AAA-BBB) is called. When the user responds with terminal A (phone number = 0-AAA-BBB), a call is established by connecting to terminal B of XX Corporation.

  However, when a malicious third party intentionally enters the telephone number of another person (victim A) in the input box 71 of the Web screen 70 and makes a call, the victim A's terminal is called and automatically responds to the call. Therefore, it is connected to the terminal B of XX Corporation. In addition, even if a third party is not malicious, if there is an input mistake in the phone number, if someone else's phone is called and responds, it is automatically connected to the terminal B of XX Corporation, which is not intended. It will be annoying.

  Therefore, in the present embodiment, in the case of a two-party call or a multi-party call under the control of a third party, the system is configured to establish a call after obtaining a connection permission of the user and / or the other party.

  FIG. 12 is a conceptual diagram of a communication system that realizes a two-party call or a multi-party call under the third party control according to the present embodiment. A state in which the user personal computer 10 accesses the service site 73 on the Internet 2 to display the Web screen 70 on the user personal computer 10 is shown. Terminal B is a telephone prepared by XX Corporation that wants to receive calls from an unspecified number of users, and the third party control system 11 uses the telephone number input in the input box 71 of the Web screen 70 as the user terminal. Call connection processing for connecting the user terminal and the terminal B is performed.

  As shown in FIG. 12, the third party control system 11 calls the user terminal A of the telephone number input in the input box 71 of the Web screen 70. At this time, there is an operation for permitting connection from the terminal A. The partner terminal B is called and connected only when the call is received. That is, on the condition that the user called to the system side performs an operation of permitting connection to terminal A, a malicious third party inputs the telephone number of user A and user's terminal A Even if it is called, a mechanism that does not automatically connect to the terminal B is constructed.

  FIG. 13 is a flowchart of a portion for requesting the user to perform a connection permission operation in the third party control system 11. When the third party control system 11 receives the connection instruction (step S70), the third party control system 11 determines whether the incoming call is restricted (step S71). As will be described later, a user device that has made a nuisance call in the past is registered, and it is checked based on the registration information whether the user who is instructed to connect by this telephone number input is subject to incoming call restriction. As registration information of the user device that made the nuisance call, the IP address of the user computer that made the nuisance call, a mobile phone number if it is a mobile phone, and other terminal-specific identification numbers can be registered.

  After confirming that it is a connection instruction from a user device that is not registered as an incoming call restriction target in step S71, the user terminal A (phone number = 03-AAA-BBB) whose phone number is entered on the Web screen 70 is displayed. A call is made (step S72). When the user responds at the terminal A (step S73), an announcement for prompting a button operation meaning connection permission is sent (step S74). For example, a message such as “Connect to XX Corporation. Please press the button“ 1 ”if you want.” When permitting connection to XX Corporation, the user presses the button “1” as a button operation for permitting connection. The third party control system 11 confirms that the button “1” has been pressed on the terminal A (step S75), and then establishes a call by connecting to the terminal B serving as the reception telephone of XX Corporation (step S75). S76).

  On the other hand, when a malicious third party different from the user of terminal A inputs the telephone number of user terminal A = 03-AAA-BBB on the Web screen 70 without permission, the user picks up the handset of terminal A. And you will hear an unexpected message. Since the user of the terminal A has not issued a connection instruction to XX Corporation, it can be processed as a suspicious call or a nuisance call. First, the user who responds at the terminal A does not perform the button operation for permitting connection, so that the third party control system 11 stops the connection to the terminal B (step S77). In the present embodiment, the user is inquired whether or not to register the nuisance transmission device that has made annoying transmission this time as an incoming call restriction target (step S78). For example, when an inquiry message as to whether or not to register as an incoming call restriction target is sent and the user performs a button operation for a registration request on the terminal A, the call is registered as an incoming call restriction target (step S79). In other words, the telephone number of terminal A is registered as an incoming call restriction target, and no incoming calls from the third party control system will be received in the future, or incoming calls for requests to connect to XX Corporation via the third party control system will be received. I will not come.

  In a system that only needs to recognize that the connection is permitted, the connection may be canceled or the button operation in the case of a mischievous telephone may be omitted to improve the operability. In addition, as a way to prevent the victim who received a mischievous call from performing unnecessary operations, instructing the button operation only for connection permission and cancellation and disconnecting the telephone without doing anything, or when the specified number does not respond for a certain period of time It is also possible to treat it as a mischievous phone.

  In the above description, the nuisance call on the user side has been described. However, the present invention can be similarly applied to the nuisance call rejection on the partner terminal side.

(Sixth embodiment)
In the sixth embodiment, prior to a two-party call or a multi-party call controlled by a third party, a user authentication is performed by inputting a dedicated authentication code presented on the Web screen at the time of response on the user terminal. This is an example in which

  FIG. 14 is a conceptual diagram of a communication system that realizes a two-party call or a multi-party call by third party control according to the present embodiment. A state in which the user personal computer 10 accesses the service site 73 on the Internet 2 to display the Web screen 70 on the user personal computer 10 is shown. The terminal B is a phone prepared by XX Corporation that wants to receive calls from an unspecified number of users. On the Web screen 70, an authentication code 74 that the user inputs when responding at the user terminal is displayed. When the user inputs the telephone number (03-AAA-BBB) of the terminal A that the user wants to receive and clicks the call button 72, the authentication code is entered together with the terminal telephone number (03-AAA-BBB) of the user terminal A that has been input. (0001) is sent to the third party control system 11.

  The third party control system 11 calls the user terminal A from the telephone number (03-AAA-BBB), and further requests input of an authentication code if there is a response. If the user of the called terminal A is the person who entered the telephone number of his / her terminal A on the Web screen 70, the user can input the authentication code (0001) displayed on the Web screen 70 with a button operation. it can. The user inputs the authentication code (0001) by operating the button on the terminal A. Thereby, the third party control system 11 confirms the match between the authentication code (0001) input by the button operation of the terminal A and the authentication code (0001) of the Web screen 70 received earlier, thereby authenticating the user. Is possible.

  On the other hand, from the viewpoint of preventing damage by a user who has used his / her phone number by a malicious third party, it is not possible to input an authentication code (0001) that the user (victim) does not know by button operation. Since there is no possibility, the connection can be stopped reliably.

  Thus, by requesting the input of the authentication code presented on the Web screen 70 at the time of response of the user terminal, the third party control system 11 can perform user authentication, while the user side makes a malicious third Can prevent annoying calls from being made.

  It is also possible to take measures such as preventing the authentication code from being input every time by displaying the authentication code only when the number is input for the first time after the telephone number is once input. The third party who used the phone number input instruction in combination with the IP address or information held by the device (mobile phone identification number for mobile phones, IP address or cookie information for personal computers, etc.) It is possible to determine whether the user telephone number is used for the first time from the control terminal or the second time.

  In the above description, the personal computer 10 is used as the user device, but a mobile phone, PHS, or other information communication device can also be used. Moreover, the system which integrated the user terminal which transmits a connection instruction | indication, and the user terminal A called from the 3rd party control system 11 may be sufficient.
