The gateway 3 also realizes a function of accessing the proxy response information management server 2 through the IP network 100A and acquiring necessary information.

The main unit 4 resolves addresses between terminals connected to the communication line, and between subordinate devices connected to the LAN 7 and between devices connected to the LAN 7 and devices connected to the wide area network 100. In addition, it functions as a small exchange for connecting telephone lines. The main device 4 of this embodiment is a SIP server that uses SIP (Session Initiation Protocol) to perform call control such as associating a telephone number with an IP (Internet Protocol) address and calling and connecting a partner. It has the function of Furthermore, the main unit 4 controls the lighting and extinguishing of LEDs (Light Emitting Diodes) of extension telephone terminals 5(1), 5(2), . It also performs various controls on subordinate terminals such as information control.

As shown in FIG. 1, each of the extension telephone terminals 5(1), 5(2), . (speaker) and a handset unit equipped with a transmitter (microphone). An extension number is assigned to each of the extension telephone terminals 5(1), 5(2), . . . Each of the extension telephone terminals 5(1), 5(2), .

The virtual terminals 6(1), . Therefore, in the main device 4, each of the virtual terminals 6(1), . In the business phone system 200 of this embodiment, the virtual terminal 6(1) is for positioning the mobile phone terminal 1 as a phone terminal under the business phone system 200 and managing it. Therefore, when a plurality of mobile phone terminals exist as telephone terminals under the business phone system 200, a plurality of virtual terminals such as virtual terminals 6(2), 6(3), . . . will be Information about the correspondence can be provided from the mobile phone terminal to the main device 4 through, for example, the IP network 100A.

By associating the mobile phone terminal owned by the user with each of the extension phone terminals 5(1), 5(2), . . . can be placed under That is, in the telephone system of this embodiment, the extension telephone terminals 5(1), 5(2), . . . and the virtual terminals 6(1), 6(2), . can be managed by associating it with a mobile phone terminal. Thereby, a mobile phone terminal such as the mobile phone terminal 1 can be positioned under the business phone system 200 . Note that the virtual terminals 6(1), 6(2), . . . are always associated with mobile phone terminals. However, if the user owns a mobile phone terminal, the extension phone terminals 5(1), 5(1), . . . can be associated with the mobile phone terminal.

The extension telephone terminals 5(1), 5(2), . . . and the virtual terminals 6(1), 6(2), . . In other words, among extension telephone terminals 5(1), 5(2), . . . and virtual terminals 6(1), 6(2), . This is a compatible phone terminal that corresponds to a mobile phone terminal.

A user who owns a mobile phone terminal associated with extension telephone terminals 5(1), 5(2), . . . or virtual terminals 6(1), 6(2), . If you want to contact yourself by telephone, ask the other party to make a call using the dial-in function of the corresponding telephone terminal. That is, the extension number assigned to the corresponding telephone terminal is notified to the other party, and how to make a call using the dial-in function. In the example shown in FIG. 1, the extension number of the extension telephone terminal 5(1) is "101" and the extension number of the extension telephone terminal 5(2) is "102". The extension number of the virtual terminal 6(1) is "501".

In this way, the user of the general external line telephone terminal 10 informed of the extension number "501" of the virtual terminal 6(1), which is the corresponding telephone terminal, is the virtual terminal 6, which is one of the corresponding telephone terminals of the business phone system 200. For (1), assume that a direct call is made using the dial-in function. In this case, in the telephone system of this embodiment, for the incoming call to the virtual terminal 6(1), which is the corresponding telephone terminal to which the direct call was made, the mobile phone associated with this virtual terminal 6(1) A proxy response can be made through the telephone terminal 1.例文帳に追加The location of the cellular phone terminal 1 that makes a proxy response is not limited. In other words, even when the mobile phone terminal associated with the corresponding phone terminal is located at an arbitrary place outside the home, it is possible to answer an incoming call to the corresponding phone terminal under the business phone system 200 by proxy.

In this way, in the telephone systems of the first and second embodiments described below, the dial-in function is used to receive an incoming call at a compatible telephone terminal, It allows the terminal to respond by proxy. There are roughly two types of processing for making a proxy response. One is to register the proxy response information required for the proxy response from the mobile phone terminal 1 to the proxy response information management server 2 . The other is to register the proxy response information required for the proxy response from the main device 4A to the proxy response information management server 2A.

Therefore, although the telephone system of the first embodiment and the telephone system of the second embodiment have the same components, there are some differences in processing in each component. For this reason, as shown in FIG. 1, the telephone system of the first embodiment is assumed to consist of a mobile telephone terminal 1, a proxy response information management server 2, and a business phone system 200. FIG. The business phone system 200 in the telephone system of the first embodiment includes the gateway 3, the main unit 4, the extension telephone terminals 5(1), 5(2), . Suppose that it consists of

On the other hand, it is assumed that the telephone system of the second embodiment comprises a mobile telephone terminal 1A, a proxy response information management server 2A, and a business phone system 200A. The business phone system 200A in the telephone system of the second embodiment includes the gateway 3, the main unit 4A, the extension telephone terminals 5(1), 5(2), . Suppose that it consists of Also in the second embodiment, it is assumed that the mobile phone terminal 1A is associated with the virtual terminal 6(1). The telephone system according to the first embodiment and the telephone system according to the second embodiment will be described below.

For example, the general external line telephone terminal 10 may be virtual terminals 6(1), 6(2), . You can make a direct call to … using the dial-in function. However, in order to simplify the explanation below, the dial-in function is used from the general telephone terminal 10 to make a call to the virtual terminal 6(1) associated with the mobile telephone terminals 1 and 1A. A specific description will be given with an example of a case where

[First embodiment]
First, the telephone system according to the first embodiment, in which proxy response information required for proxy response is registered in the proxy response information management server 2 from a cellular phone terminal, will be described. In the first embodiment, as in the above-described example, the telephone terminal 10 uses the dial-in function to make a call to the virtual terminal 6(1) whose extension number is 501 in the business phone system 200. 6(1) is answered through the mobile phone terminal 1 as an example.

<Outline of notification processing of incoming call to mobile phone terminal 1>
FIG. 2 is a diagram for explaining the process of notifying the mobile phone terminal 1 associated with the virtual terminal 6(1), which is the corresponding phone terminal in which a dial-in incoming call has occurred, of the incoming call. The general external line telephone terminal 10 uses the external line telephone number assigned to the business phone system 200 and the extension number "501" assigned to the virtual terminal 6(1) to form an originating message, which is then transferred to the public switched telephone network. 100C (process Pr1).

The outgoing message from the general telephone terminal 10 is received by the gateway 3 of the business phone system 200 and provided to the main device 4 through the LAN 7 (process Pr2). In response to the incoming call from the general outside line telephone terminal 10, the main device 4 connects and holds the call line, and makes an incoming call to the destination virtual terminal 6(1) (process Pr3). In this case, since the virtual terminal 6(1) does not exist as a physical terminal, only a signal for incoming call is sent from the main device 4. FIG. However, if the called party is an actual extension telephone terminal 5(1), 5(2), .

Further, the main device 4 identifies the mobile phone terminal 1 associated with the virtual terminal 6(1) in accordance with the management information of its own address management DB (Data Base), which will be described in detail later. , and forms an incoming call notification request for requesting the mobile phone terminal 1 to notify the incoming call. Then, main device 4 transmits the formed incoming notification request to association server 9 through IP network 100A (process Pr4). As identification information of the mobile phone terminal 1, a mobile phone number, an IP address, or the like can be used.

Correlation server 9 identifies mobile phone terminal 1 based on the identification information included in the incoming call notification request from main device 4, and sends virtual terminal 6 ( 1) is notified that there is an incoming call (process Pr5). In this way, when there is a direct incoming call to the corresponding telephone terminal using the dial-in function, the main device 4 sends the corresponding telephone terminal to the mobile telephone terminal associated with the corresponding telephone terminal through the route through the IP network 100A. The terminal is notified that there is an incoming call.

<Overview of Proxy Response Processing Using Mobile Phone Terminal 1>
FIG. 3 is a diagram for explaining the processing when the mobile phone terminal 1 associated with the virtual terminal 6(1), which is the corresponding phone terminal for which a dial-in incoming call has occurred, makes a proxy response to the incoming call. . As described with reference to FIG. 2, when the user of the mobile phone terminal 1 notified of an incoming call to the virtual terminal 6(1) responds to the incoming call by proxy, the mobile phone terminal 1 has a Start the extension phone application described above. Note that the extension phone application can be activated by a simple operation such as tapping on the display that notifies the virtual terminal 6(1) that there is an incoming call. Further, the extension phone application may be automatically activated when receiving a notification that there is an incoming call to the virtual terminal 6(1).

When the extension phone application is activated, the mobile phone terminal 1 displays a "proxy response button" as a software key on the display unit, and accepts an instruction input to the button as a response operation. When the response operation is accepted, the mobile phone terminal 1 forms proxy response information by the extension phone application, transmits it to the proxy response information management server 2 via the IP network 100A, and registers it (process Pr11). The proxy response information, which will be described in detail later, consists of identification information of the mobile phone terminal 1, identification information of the terminal to which the proxy response is to be made, and information for instructing the proxy response. Proxy response information management server 2 receives and stores proxy response information transmitted from mobile phone terminal 1 through IP network 100A.

Next, the mobile phone terminal 1 uses the extension phone application to form an outgoing message for the business phone system 200 under which the mobile phone terminal 1 is positioned, and transmits the message to the business phone system 200 via the mobile phone network 100B and the public switched telephone network 100C. (Process Pr12). In other words, the process Pr12 is a process in which the mobile phone terminal 1 makes a call to the business phone system 200 through the telephone network. However, the mobile phone terminal 1 makes a call to a dedicated phone number assigned in advance to the business phone system 200 for receiving a request for a proxy response from a mobile phone terminal positioned under its own system.

Assume that the gateway 3 of the business phone system 200 accepts an incoming call from the mobile phone terminal 1 to the dedicated phone number. In this case, the gateway 3 requests the proxy response information management server 2 via the IP network 100A to provide the proxy response information registered in the proxy response information management server 2 by the caller mobile phone terminal 1 (process Pr13). ). The request includes, for example, a mobile phone number as identification information of the mobile phone terminal 1 , and the proxy response information management server 2 searches for proxy response information including the mobile phone number of the mobile phone terminal 1 . and. Proxy response information management server 2 provides the retrieved proxy response information to gateway 3 through IP network 100A (process Pr14).

Upon receipt of the proxy response information from the proxy response information management server 2, the gateway 3 mainly instructs the mobile phone terminal 1 to make a proxy response to the incoming call to the virtual terminal 6(1) based on the proxy response information. The device 4 is instructed (process Pr15). In response to the instruction, main device 4 connects and maintains a call line with mobile phone terminal 1 through mobile phone network 100B and public switched telephone network 100C, and receives an incoming call to virtual terminal 6(1). is canceled (process Pr16).

Then, the main device 4 connects the communication line with the general outside line telephone terminal 10 previously held by the processes Pr1 and Pr2 of FIG. Connects a telephone line between As a result, between the general outside line telephone terminal 10 calling the virtual terminal 6(1) and the mobile telephone terminal 1 calling the dedicated telephone number of the business phone system 200 for proxy response, A telephone line TL is connected as indicated by a dotted line in FIG. As a result, a call can be made between the general telephone terminal 10 and the mobile phone terminal 1 through the telephone line TL.

In this way, when the mobile phone terminal 1 directly calls the virtual terminal 6(1) associated with itself using the dial-in function and receives an incoming call, You can answer incoming calls on your behalf. Moreover, the mobile phone terminal 1 can make a proxy response from any place such as outside. Then, as shown in FIG. 3, the call line between the mobile phone terminal 1 and the general external phone terminal 10 is through a mobile phone network 100B and a public switched telephone network 100C, which are call networks that guarantee voice quality. Since the connection is made, the voice of the call is not degraded, and the call can be made stably with high quality.

Upon receiving the proxy response request, the main device 4 holds the communication line with the mobile phone terminal 1 of the caller, and terminates the incoming call notification (incoming call) to the virtual terminal 6(1) started in step S3 ( step S16).

Thereafter, in the main device 4, under the control of the control unit 110, the proxy response processing unit 408 functions to execute proxy response processing (step S17). Specifically, the proxy response processing unit 408 stores the call line between the caller's general external line telephone terminal 10 and the A call line is connected to the held mobile phone terminal 1.例文帳に追加As a result, the general outside line telephone terminal 10 and the mobile telephone terminal 1 are connected by a telephone line through the mobile telephone network 100B and the public switched telephone network 100C via the main unit and the gateway 3 of the business phone system 200 (step S18). . As a result, the mobile phone terminal 1 can make a proxy response to the incoming call to the virtual terminal 6 ( 1 ), and the general outside line phone terminal 10 and the mobile phone terminal 1 can be used to make a call.

[Processing in Each Device Constituting the Telephone System]
Next, each of the cellular phone terminal 1, the proxy response information management server 2, the gateway 3, and the main device 4, which constitute the telephone system of this embodiment, which operates as described with reference to the sequence diagram of FIG. Processing will be explained.

<Processing of mobile phone terminal 1>
FIG. 11 is a flow chart for explaining the processing performed by the mobile phone terminal 1 according to the first embodiment. The processing shown in FIG. 11 is executed when the extension phone application is activated in the mobile phone terminal 1 notified by the push notification that there is an incoming call to the virtual terminal 6(1). As described above, the activation of the extension phone application can be triggered by performing a predetermined operation to activate the extension telephone application after the push notification, or by automatically activating the extension telephone application after the push notification. There are at least two cases where

Assume that an opportunity to activate the extension phone application has arrived. In this case, control unit 110 activates the extension phone application (step S101), displays a proxy response button on display unit 106D, and receives a response operation instructing a proxy response through touch panel 106 (step S102). ). Then, control unit 110 determines whether or not a response operation instructing a proxy response has been received (step S103). When it is determined in the determination process of step S103 that the response operation for making a proxy response has not been accepted, it is determined whether or not an operation to terminate the extension telephone application has been performed (step S104).

Assume that it is determined in the determination process of step S104 that an operation to end the extension phone application has been performed. In this case, control unit 110 performs a predetermined termination process such as returning the display on display unit 106D to the state before execution of the extension telephone application (step S105), thereby terminating the extension telephone application. Further, when it is determined in the determination processing of step S104 that the operation to terminate the extension telephone application has not been performed, the processing from step S102 is repeated.

Assume that it is determined in the determination process of step S103 that a response operation instructing a proxy response has been received. In this case, proxy response information processing section 122 functions to form proxy response information (FIG. 6A) and transmit it to proxy response information management server 2 through IP network 100A (step S106). Next, the origination processing unit 123 functions to form an origination message to the dedicated telephone number of the business phone system 200 and transmit it through the telephone network, ie, in this embodiment, the mobile telephone network 100B and the public switched telephone network 100C. (Step S107).

Then, control unit 110 determines whether or not a response message has been transmitted from business phone system 200 (step S108). When it is determined in the determining process of step S108 that a response message has been sent, the control section 110 performs processing to connect the telephone line (step S109). As a result, in this embodiment, a call line is connected to the general outside line telephone terminal 10 to which the call is made, and the call is made through the wireless communication unit 101, the transmission/reception signal processing unit 102, and the call voice processing unit 103. made possible.

After that, the control unit 110 receives an operation input from the user (step S110), and determines whether or not an on-hook operation has been performed (step S111). When it is determined in the determination processing of step S111 that the on-hook operation is not performed, the processing from step S110 is repeated. When it is determined in the determination process of step S111 that the on-hook operation has been performed, a predetermined termination process such as restoring the display of the display unit 106D is performed (step S112), and the extension phone application is terminated.

Further, when it is determined in the determining process of step S108 that the response message has not been sent, the control section 110 accepts an operation input from the user (step S113). Thereafter, in step S113, control unit 110 determines whether or not an on-hook operation has been received (step S114). When it is determined in the determination processing of step S114 that the on-hook operation is not accepted, the processing from step S108 is repeated. When it is determined that the on-hook operation has been received in the determination process of step S114, predetermined end processing such as restoring the display of the display unit 106D is performed (step S112), and the extension phone application is terminated.

In this way, when the user of the mobile phone terminal 1 receives a push notification that there is an incoming call to the associated virtual terminal 6(1), the user sends the call to the virtual terminal 6(1) through the mobile phone terminal 1. It is possible to perform a response operation so as to make a proxy response to the incoming call. In this case, the proxy response information necessary for the proxy response can be provided and managed by the proxy response information management server 2 through the IP network 100A. Then, the mobile phone terminal 1 calls the dedicated phone number of the business phone system 200 through the mobile phone network 100B and the public switched telephone network 100C, and receives the incoming call from the virtual terminal 6(1) to the business phone system 200. You can request to respond on your behalf.

<Processing of Proxy Response Information Management Server 2>
FIG. 12 is a flow chart for explaining the processing performed by the proxy response information management server 2 according to the first embodiment. The control unit 202 of the proxy response information management server 2 always executes the processing shown in FIG. Then, the control unit 202 receives a request addressed to itself or proxy response information (hereinafter referred to as a request or the like) through the connection terminal 201T and the communication I/F 201 (step S201). is received (step S202).

When it is determined in the determination processing of step S202 that a request addressed to the device itself has not been received, the processing from step S201 is repeated. Suppose that it is determined in the determination processing of step S202 that a request or the like addressed to the device itself has been received. In this case, the control unit 202 determines whether the received request or the like is proxy response information having the configuration shown in FIG. 6A from the mobile phone terminal (step S203). Suppose that it is determined that the received request or the like is proxy response information in the determination processing of step S203. In this case, the control unit 202 controls the proxy response information receiving unit 205 to receive the proxy response information from the mobile phone terminal and record it in the proxy response information memory 204 (step S204). After that, the control unit 202 repeats the processing from step S201.

In addition, when it is determined in the determination processing in step S203 that the received request etc. is not the proxy response information from the mobile phone terminal, the control unit 202 determines that the received request etc. is the proxy response information provided from the gateway 3. It is determined whether or not it is a provision request (step S205). Assume that it is determined in the determination processing in step S205 that the received request or the like is a request for provision of proxy response information. In this case, the control unit 202 controls and accepts the request for provision, provides the mobile phone number included in the request for provision to the proxy response information search unit 207, and searches for the corresponding proxy response information. (step S206).

As a result, proxy response information search unit 207 searches and extracts the corresponding proxy response information based on the mobile phone number from provision request reception unit 206, and sends the extracted proxy response information to proxy response information provision unit 208. supply to The proxy response information providing unit 208 performs a process of providing the proxy response information from the proxy response information searching unit 207 to the request source gateway 3 (step S207). After that, the process from step S201 is repeated. Assume that the received request or the like is determined not to be a proxy response information provision request in the determination process of step S205. In this case, the control unit 202 executes processing according to the received request (step S208), and then repeats the processing from step S201.

In this manner, the proxy response information management server 2 can receive provision of proxy response information from mobile phone terminals associated with virtual terminals and extension telephone terminals of the business phone system 200, and can manage this. Also, the proxy response information management server 2 registers mobile phone terminals associated with virtual terminals and extension telephone terminals of the business phone system 200 in the proxy response information management server 2 in response to a request from the gateway 3 . proxy response information can be provided.

<Processing of Gateway 3>
FIG. 13 is a flowchart for explaining the processing performed by the gateway 3 of the telephone system according to the first embodiment. The controller 302 of the gateway 3 always executes the processing shown in FIG. Then, the control unit 302 receives an incoming call (outgoing message) addressed to the own device via the connection terminal 301T and the line I/F 301 (step S301), and determines whether or not an incoming call addressed to the own device has occurred. (Step S302).

When it is determined in the determining process of step S302 that an incoming call addressed to itself has not occurred, the control section 302 repeats the processes from step S301. Assume also that it is determined in the determining process of step S302 that an incoming call addressed to itself has occurred. In this case, the control unit 302 determines whether or not the incoming call is an incoming call to a dedicated telephone number for proxy answering from a mobile telephone terminal associated with a virtual terminal or an extension telephone terminal of the business phone system 200 (step S303).

When it is determined in the determining process in step S303 that the incoming call is to the dedicated telephone number, the control unit 302 controls the proxy response information requesting unit 305 to form a proxy response information provision request and perform proxy response information management. A process of transmitting to the server 2 is executed (step S304). In response to this, proxy response information management server 2 transmits proxy response information for enabling proxy response using the mobile phone terminal of the caller to the dedicated telephone number. Therefore, the control unit 302 of the gateway 3 receives (acquires) this through the connection terminal 301T and the line I/F 301 (step S305), controls the proxy response request providing unit 306, and generates a proxy response request based on the proxy response information. is formed and provided to the main device 4 (step S306). After that, the control unit 302 repeats the processing from step S301.

If it is determined in the determining process in step S303 that the incoming call is not to the dedicated telephone number, the control unit 302 determines whether the current incoming call is a direct incoming call to a virtual terminal or extension telephone terminal using the dial-in function. It is determined whether or not (step S307). When it is determined by the determination processing in step S307 that the incoming call is direct to a virtual terminal or extension telephone terminal using the dial-in function, the gateway function unit 307 functions to notify the main device 4 of the dial-in incoming call. (Step S308). As a result, the main device 4 performs a process of requesting an incoming call notification to the virtual terminal or the extension telephone terminal or a push notification of an incoming call to the mobile phone terminal associated with these terminals.

Further, when it is determined by the determination processing in step S307 that the incoming call is not a direct call to a virtual terminal or extension telephone terminal using a dial-in function, the main unit is notified of the normal incoming call (step S309). As a result, the main unit 4 notifies the extension telephone terminal under its control of the incoming call, connects the telephone line between the extension telephone terminal having the response operation and the telephone terminal of the caller, and makes it possible to make a call. After the process of step S308 and after the process of step S309, the control unit 302 repeats the process from step S301.

Thus, the gateway 3 realizes the function of connecting the public switched telephone network 100C and the business phone system 200. FIG. Then, the gateway 3 can acquire the proxy response information from the proxy response information management server 2, triggered by an incoming call to the dedicated telephone number from the mobile phone terminal associated with the virtual terminal or the extension telephone terminal of the business phone system 200. . Furthermore, the gateway 3 can request the main device 4 to make a proxy response through the mobile phone terminal of the caller to the dedicated telephone number based on the obtained proxy response information.

<Processing of main unit 4>
FIG. 14 is a flow chart for explaining the processing performed by the main unit 4 of the telephone system according to the first embodiment. The control unit 402 of the main device 4 always executes the processing shown in FIG. Then, the control unit 402 receives a request addressed to itself through the connection terminal 401T and the LAN I/F 401 (step S401), and determines whether or not a request addressed to itself has been received (step S402). ).

When it is determined in the determination processing of step S402 that a request addressed to the device itself has not been received, the control unit 402 repeats the processing from step S401. Assume also that it is determined in the determination processing of step S402 that a request or the like addressed to itself has been received. In this case, the control unit 402 determines whether the received request or the like is for notifying a dial-in incoming call from the gateway 3 (step S403). Whether or not the incoming call is a dial-in call can be determined by the presence or absence of an extension number.

Assume that it is determined in the determining process of step S403 that the received request or the like is for notifying a dial-in incoming call from the gateway 3. FIG. In this case, the control unit 402 controls the call control unit 405 and the terminal control unit 406 to notify the corresponding telephone terminal, that is, the virtual terminal or the extension telephone terminal, of the incoming call (step S404). . Furthermore, the control unit 402 controls the incoming call notification requesting unit 407 to form an incoming call notification request, and performs processing for transmitting this to the association server 9 (step S405). The process of step S405 is to notify the mobile phone terminal associated with the corresponding phone terminal that has received the call that the corresponding phone terminal has received the call by push notification. This is the processing required for After the processing of step S405, the control unit 402 repeats the processing from step S401.

Assume also that it is determined in the determination processing in step S403 that the received request or the like is not for notifying a dial-in incoming call from the gateway 3. FIG. In this case, the control unit 402 determines whether the received request or the like is a proxy response request from the gateway 3 (step S406). When it is determined that the received request or the like is a proxy response request from the gateway 3 in the determination processing of step S406, the control unit 402 controls the proxy response processing unit 408 to execute proxy response processing (step S407). ).

In the process of step S407, the mobile phone terminal associated with the virtual terminal or the extension phone terminal that has received the direct-in incoming call, and the mobile phone terminal calling the dedicated phone number This is a process of making a proxy response to an incoming call. As a result, in the case of the above-described first embodiment, the caller general external telephone terminal 10 and the mobile telephone terminal 1
A call line is connected between the two, and a call can be made.

Assume also that it is determined that the received request or the like is not a proxy response request from the gateway 3 in the determining process of step S406. In this case, the control unit 402 controls the call control unit 405 and the terminal control unit 406 to execute processing according to the received request (step S408). In step S408, normal outgoing call processing, incoming call processing, and the like are performed. As a result, a telephone call can be made by connecting a telephone line to the other party.

Then, after the processes of steps S407 and S408, the control unit 402 determines whether or not an event for ending the process to be executed has occurred (step S409). That is, in steps S407 and S408, the telephone line is connected to make a call, or a call is being made to connect the telephone line. Therefore, in step S409, it is determined whether or not a predetermined termination event such as an on-hook operation has occurred in the extension telephone terminal connected to the called party or the main unit 4 or not.

If it is determined in the determination processing of step S409 that the termination event has not occurred, the processing from step S409 is repeated, and the termination event of the processing to be executed is waited for. Further, when it is determined in the determination processing of step S409 that an end event has occurred, predetermined termination processing such as terminating the call or releasing the connected communication line is performed (step S410), The processing from step S401 is repeated.

In this way, the main unit 4 performs normal call control, and also receives a dial-in incoming call to a virtual terminal or extension telephone terminal. A terminal can be used to make a proxy response.

[Second embodiment]
Next, a telephone system according to a second embodiment in which proxy response information necessary for proxy response is registered in the proxy response information management server 2A from the main device 4A will be described. In the second embodiment, it is assumed that the general telephone terminal 10 uses the dial-in function to make a call to the virtual terminal 6(1) whose extension number is 501 in the business phone system 200A. An example of a case where an incoming call to the virtual terminal 6(1) is answered through the mobile phone terminal 1A associated with the virtual terminal 6(1) will be described as an example.

<Outline of notification processing of incoming call to mobile phone terminal 1>
FIG. 15 is a diagram for explaining the process of notifying the mobile phone terminal 1A associated with the virtual terminal 6(1), which is the corresponding phone terminal in which the dial-in incoming call has occurred, of the incoming call. Also in FIG. 15, the same reference numerals as in FIG. 2 denote the same processes as those shown in FIG. 2 and the same devices as those shown in FIG.

The general external telephone terminal 10 forms an originating message using the external telephone number assigned to the business phone system 200A and the extension number "501" assigned to the virtual terminal 6(1), and transmits the message to the public switched telephone network. 100C (process Pr1). The outgoing message from the general telephone terminal 10 is received by the gateway 3 of the business phone system 200A and provided to the main device 4A through the LAN 7 (process Pr2). In response to the incoming call from the general outside line telephone terminal 10, the main device 4A connects and holds the call line, and makes an incoming call to the destination virtual terminal 6(1) (process Pr3). In this case, since the virtual terminal 6(1) does not exist as a physical terminal, only a signal for incoming call is sent from the main device 4A.

Further, the main device 4A, according to the management information (FIG. 9A) of its own address management DB 404 configured in the same manner as the main device 4 of the first embodiment, Proxy response information is formed for enabling a proxy response through the mobile phone terminal 1A associated with the terminal 6(1). Then, the main device 4A provides and registers the formed proxy response information to the proxy response information management server 2A through the IP network 100A (process Pr4A). The proxy response information formed by the main device 4A is the same as that shown in FIG. 6(A).

The proxy response information management server 2A that receives the proxy response information from the main device 4A registers the proxy response information in the proxy response information memory. Further, the proxy response information management server 2A forms an incoming call notification request based on the proxy response information from the main device 4A, and transmits it to the association server 9 through the IP network 100A (process Pr5A). The incoming call notification request requests the mobile phone terminal 1 associated with the virtual terminal 6(1) to notify the virtual terminal 6(1) of an incoming call by push notification. It is. Correlation server 9 identifies mobile phone terminal 1 based on the identification information included in the incoming call notification request from main device 4, and sends virtual terminal 6 ( 1) is notified that there is an incoming call (process Pr6A).

As described above, the telephone system of the second embodiment is characterized by the functions provided by the main unit 4A. That is, the main unit 4A performs normal call control, and when a dial-in incoming call occurs to the corresponding telephone terminal associated with the mobile telephone terminal, the main unit 4A forms proxy response information and sends it. It has a function of providing and registering in the proxy response information management server 2 . Also, the proxy response information management server 2A, which receives the proxy response information from the main device 4A, not only manages and provides the proxy response information. When the proxy response information management server 2A receives the proxy response information from the main device 4A, the proxy response information management server 2A sends a push notification to the mobile phone terminal associated with the corresponding phone terminal that there is an incoming call at the corresponding phone terminal. Processing for requesting the association server 9 to notify is also performed.

<Overview of Proxy Response Processing Using Mobile Phone Terminal 1>
FIG. 16 shows the case where the mobile phone terminal 1A associated with the virtual terminal 6(1), which is the corresponding phone terminal for which a dial-in incoming call has occurred, makes a proxy response to the incoming call, as described with reference to FIG. 3 is a diagram for explaining the processing of . In FIG. 16 as well, the same reference numerals as in FIG. 2 denote the same processes as those shown in FIG. 3 and the same devices as those shown in FIG.

As in the case of the first embodiment described with reference to FIG. 3, when the user of the mobile phone terminal 1A notified of the incoming call to the virtual terminal 6(1) responds to the incoming call by proxy. Then, the above-described extension phone application installed in the mobile phone terminal 1 is activated. As described above, the extension phone application can be activated by a simple operation such as touching the display for notifying that there is an incoming call on the virtual terminal 6(1). Also, the extension phone application may be automatically activated when receiving a push notification that there is an incoming call to the virtual terminal 6(1).

When the extension phone application is activated, a "proxy response button" is displayed as a software key on the display screen of the mobile phone terminal 1, and an instruction input to the button is accepted as a response operation. When the response operation is accepted, the mobile phone terminal 1 forms an outgoing message for the business phone system 200 using the extension phone application, and transmits the message to the business phone system 200 through the mobile phone network 100B and the public switched telephone network 100C (process Pr12). In other words, the process Pr12 is a process in which the mobile phone terminal 1 makes a call to the business phone system 200 through the telephone network. However, the mobile phone terminal 1 makes a call to a dedicated phone number assigned in advance to the business phone system 200 for receiving a request for a proxy response from a mobile phone terminal positioned under its own system.

It is assumed that the gateway 3 of the business phone system 200 receives an incoming call to the dedicated telephone number from the mobile phone terminal 1 under its own system. In this case, as described with reference to FIG. 15, the gateway 3 provides the proxy response information registered in the proxy response information management server 2A by the main device 4A to the proxy response information management server 2A via the IP network 100A. (processing Pr13). The request includes, for example, a mobile phone number as the identification information of the mobile phone terminal 1A. and. The proxy response information management server 2A provides the searched proxy response information to the gateway 3 through the IP network 100A (process Pr14).

Upon receiving the proxy response information from the proxy response information management server 2A, the gateway 3, based on the proxy response information, instructs the mobile phone terminal 1A to make a proxy response to the incoming call to the virtual terminal 6(1). The main device 4A is instructed (process Pr15). In response to the instruction, main device 4A connects and maintains a call line with mobile phone terminal 1A through mobile phone network 100B and public switched telephone network 100C, and receives an incoming call to virtual terminal 6(1). is canceled (process Pr16).

Then, the main device 4A connects the communication line with the general outside line telephone terminal 10 previously held by the processes Pr1 and Pr2 of FIG. Connects a telephone line between As a result, between the general outside line telephone terminal 10 calling the virtual terminal 6(1) and the mobile telephone terminal 1A calling the dedicated telephone number of the business phone system 200 for proxy response, A telephone line TL is connected as indicated by a dotted line in FIG. A call can be made between the general telephone terminal 10 and the mobile telephone terminal 1A through the telephone line TL.

In the case of the telephone system of the second embodiment, the proxy response information is provided from the main device 4A to the proxy response information management server 2A and registered as described with reference to FIG. This eliminates the need for the mobile phone terminal 1A to form the proxy response information, provide it to the proxy response information management server 2A, and register it. Therefore, as can be seen by comparing FIG. 3 and FIG. 16, when the mobile phone terminal 1A receives a push notification that there is an incoming call to the associated virtual terminal 6(1), the business phone system 200 A proxy response to an incoming call to the virtual terminal 6(1) can be made by simply calling the dedicated telephone number of the virtual terminal 6(1).

Thus, in the second embodiment as well, the mobile phone terminal 1A uses the dial-in function to directly make a call to the virtual terminal 6(1) with which it is associated. When an incoming call is received by a mobile phone, it is possible to make a proxy response to the incoming call. Moreover, the mobile phone terminal 1A can make a proxy response from any place such as outside. As shown in FIG. 16, the call line between the mobile phone terminal 1 and the general outside line phone terminal 10 is connected to the mobile phone network 100B and the public switched telephone network 100C, which are call networks. Stable, high-definition calls can be made without voice deterioration.

<Configuration example of devices that make up the telephone system>
Next, a configuration example of the mobile phone terminal 1A, the proxy response information management server 2A, and the main device 4A, which are components of the business phone system 200, which constitute the telephone system of the second embodiment will be described. In the telephone system of the second embodiment, the gateway 3, which is a component of the business phone system 200, is the same as that of the first embodiment, so the explanation of the gateway 3 is omitted. .

<<Configuration example of mobile phone terminal 1>>
FIG. 17 is a block diagram for explaining a configuration example of the mobile phone terminal 1A according to the second embodiment. In the mobile phone terminal 1A of the second embodiment shown in FIG. 17, the mobile phone terminal 1 and the The same reference numerals are given, and the description of the relevant parts is omitted.

As can be seen by comparing FIG. 17 and FIG. 4, the cellular phone terminal 1A of the second embodiment differs from the first embodiment in that it does not include the proxy response information processing section 122 in the extension telephone function section 120A. It is different from the mobile phone terminal 1 in form. This is because, as described above, the main device 4A forms proxy response information, provides it to the proxy response information management server 2A, and registers it.

Therefore, in the mobile phone terminal 1A of the second embodiment, when there is an incoming call using the dial-in function in the associated virtual terminal and this is notified by push notification, the incoming call notification processing unit 121 It functions to perform processing for notifying the user of the mobile phone terminal 1A. Then, when the user of the mobile phone terminal 1A makes a proxy response to the virtual terminal 6(1), the outgoing call processing unit 123 functions, and simply calls the dedicated phone number of the business phone system 200, and the virtual terminal 6(1) can be answered by proxy.

<<Configuration example of proxy response information management server 2>>
FIG. 18 is a block diagram for explaining a configuration example of the proxy response information management server 2A according to the second embodiment. In the proxy response information management server 2A of the second embodiment shown in FIG. 18, a proxy The same reference numerals as those of the response information management server 2 are attached, and the description of the relevant portions is omitted.

As can be seen from a comparison between FIG. 18 and FIG. 5, the proxy response information management server 2A of the second embodiment is provided with an incoming call notification requesting unit 209, unlike the proxy response information management server of the first embodiment. 2 different. That is, in the first embodiment, the main device 4 provides an incoming call notification request to the association server 9, and pushes notification to the mobile phone terminal 1 that an incoming call has occurred at the virtual terminal 6(1). I was requesting so.

However, in the second embodiment, the main device 4A forms proxy response information, provides it to the proxy response information management server 2A, and registers it. Therefore, in the second embodiment, when proxy response information is provided, the incoming call notification requesting unit 209 of the proxy response information management server 2A functions to provide an incoming call notification request to the association server 9. do. As a result, the proxy response information management server 2A can request the correspondence server 9 to send a push notification to the mobile phone terminal 1 that an incoming call has occurred at the virtual terminal 6(1).

The proxy response information reception unit 205 of the proxy response information management server 2A of the second embodiment receives the proxy response information provided from the main device 4A through the IP network 100A and stores it in the proxy response information memory 204. The registration process is performed.

<<Configuration example of the main device 4>>
FIG. 19 is a block diagram for explaining a configuration example of the main device 4A of the second embodiment. In the main unit 4A of the second embodiment shown in FIG. 19, the same reference numerals as those of the main unit 4 are used for the parts configured in the same manner as the main unit 4 of the first embodiment described with reference to FIG. , and the description of this part is omitted.

As can be seen from a comparison of FIG. 19 and FIG. 8, main apparatus 4A of the second embodiment does not include incoming call notification requesting section 407, but includes proxy response information providing section 409. is different from the main unit 4 in the form of As described above, in the second embodiment, the main device 4A forms proxy response information, provides it to the proxy response information management server 2A, and registers it.

[Processing when proxy response to incoming call to virtual terminal 6(1) via mobile phone terminal 1A]
FIG. 20 is for explaining the processing in the case of making a proxy response through the mobile phone terminal 1A to an incoming call from the general outside line phone terminal 10 to the virtual terminal 6(1), which is the corresponding phone terminal, in the second embodiment. is a sequence diagram of. In the process for making a proxy response according to the second embodiment shown in FIG. 20, the parts that are performed in the same manner as the process for making a proxy response according to the first embodiment described with reference to FIG. They are given the same reference numerals.

As shown in FIG. 20, it is assumed that the user of the general line telephone terminal 10 uses the dial-in function to make a call to the virtual terminal 6(1) of the business phone system 200A using the general line telephone terminal 10. (Step S0). In this step S0, the telephone number assigned to the business phone system 200A through the general outside line telephone terminal 10, a predetermined symbol such as "*", and the extension number "501" of the virtual terminal 6(1) are input. Try to call 6(1) directly.

A call origination message formed in accordance with the call origination operation in step S0 is sent from the general telephone terminal 10 to the public switched telephone network 100C, and transmitted to the gateway 3 of the business phone system 200A (step S1). In the gateway 3, the transmission message is received through the connection terminal 301T and the line I/F 301, the gateway function unit 307 functions to convert it into data in a format that can be processed in its own system, and the data is sent to the main unit 4A through the LAN 7. Send (step S2).

When the main device 4A receives the outgoing message from the gateway 3, the call control unit 405 functions to hold the call line with the general external telephone terminal 10 of the sender, and the virtual terminal 6 (1) of the called party. ), an incoming call notification (incoming call) is started (step S3). Since virtual terminal 6(1) is virtually connected, incoming call notification processing such as incoming call ringing is not actually performed. However, when the destination of the incoming call notification (call destination) is the extension telephone terminal 5(1) or the like, the incoming call notification processing such as ringing is performed by the incoming call notification from the main device 4A.

Then, in the main device 4A, the proxy response information providing unit 409 functions to generate the proxy response information (Fig. 6(A)). The proxy response information providing unit 409 then transmits the formed proxy response information to the proxy response information management server 2A through the IP network 100A (step S4A).
