Description

  The present invention relates to telephone transfer, and more particularly to transfer to a telephone terminal that includes an input device and a display device like a general mobile phone terminal and can display a web browser.

  There is a so-called transfer telephone as a technique for receiving an incoming call to an office telephone terminal even at a destination. With the widespread use of mobile phones, the need for transfer telephones is increasing.

  A conventional transfer telephone is generally performed as follows. When a caller calls the office and receives a call at an office private branch exchange, a button telephone device, or a telephone transfer device (hereinafter, these devices are collectively referred to as a transfer device), the transfer device receives a predetermined transfer destination. Make a call to the phone terminal. When the transfer destination telephone terminal responds, the transfer device connects the incoming call of the caller to the transfer destination.

  On the other hand, telecommunications carriers provide a caller ID notification service as a telephone additional service. In this service, a signal indicating the telephone number of the calling terminal is notified to the receiving terminal together with the incoming call. By using this service, the user of the receiving terminal can know the telephone number of the caller before starting the call.

  Consider a case where a call to an office is transferred to a mobile phone terminal while using a caller ID notification service. A general mobile phone terminal includes a display device. When an incoming call is detected, the telephone number of the office that is the source of the transfer call is displayed on the display device, but the telephone number of the caller cannot be displayed. For this reason, the user of the mobile phone terminal can identify whether a call originated by someone in the office has arrived, or whether someone outside the office has originated a call and the call forwarded from the office has arrived before going off-hook. Can not do it.

  Some phone numbers are designated as forwarding numbers, and when making a call for forwarding, the forwarding number is used to transfer whether the incoming call is a forwarding call based on the notified phone number. It is possible to configure to identify at the destination terminal. However, even in this case, it is only known whether the call is a transfer call, and the telephone number of the caller is not known.

  Patent document 1 is illustrated as literature in which the invention relevant to a transfer telephone was described. In Patent Document 1, when an INVITE message is received from a source SIP telephone terminal, an originator number and a destination number are acquired from the received INVITE message, and an INVITE message including customer information corresponding to the acquired originator number is provided. A SIP server is described in which customer information corresponding to a caller number is notified to a transfer destination SIP telephone terminal by being generated and transmitted to the transfer destination SIP telephone terminal.

  The Web server 6 includes an http request analysis unit 40, an html document creation unit 41, an http response transmission unit 42, and a storage unit 43. Hereinafter, the Web server 6 will be described with further reference to FIG.

  The http request analysis unit 40 analyzes an http request received via the Internet 8 and determines whether or not the terminal unique identifier stored in the storage unit 43 in advance as the terminal unique identifier of the transfer destination terminal 5 is included. Further, when a control link described later is included in the http request, the http request analysis unit 40 transmits a control signal corresponding to the control link to the transfer apparatus 2.

  When the http request analysis unit 40 determines that the terminal unique identifier of the transfer destination terminal 5 is included in the http request, the html document creation unit 41 creates an html document and passes it to the http response transmission unit 42.

  The http response transmission unit 42 creates an http response including the HTML document created by the HTML document creation unit 41, and transmits it via the Internet 8 to the terminal that sent the http request analyzed by the http request analysis unit 40. To do.

  The storage unit 43 stores the terminal unique identifier of the telephone terminal registered in the transfer device 2 as the transfer destination terminal 5. Further, the telephone number of the caller of the incoming call to the transfer device 2 notified from the control unit 30 of the transfer device 2 is stored. For example, the terminal unique identifier XYZ of the transfer destination terminal 5 and the telephone number 03-1111-2222 of the caller terminal 9 are stored in the storage unit 43.

  Further, the storage unit 43 stores various information related to the telephone number in association with the telephone number. Examples of such information include incoming histories such as date, time, call time, etc. received from the telephone number, and various names such as the subscriber name and company name of the telephone number. The contents of the storage unit 43 may be stored in the storage unit 32 of the transfer device 2 and referred to by the Web server 6 as necessary. The storage unit 32 and the storage unit 43 may be a single storage device.

  When the terminal unique identifier of the transfer destination terminal 5 is included in the http request and the transfer device 2 is informed by the transfer setting notification that the transfer function is activated, the html document creation unit 41 stores the storage unit 43. An html document in which the telephone number (03-1111-2222) of the source terminal 9 stored in is written is created. An html document describing information stored in the storage unit 43 in association with the telephone number, such as a subscriber name of the telephone number, may be created together with the telephone number or instead of the telephone number. In addition, the incoming call history from the telephone number may be described in the html document.

  Further, in addition to the above information, the html document creation unit 41 describes an instruction for remotely operating the transfer device 2 from the transfer destination terminal 5 via the mobile communication network 7 and the Internet 8 as a link in the html document. May be. Such a link is called a control link.

  The control link includes a text character string displayed on the display unit 14 of the transfer destination terminal 5 in order to explain the content of the instruction given to the transfer device 2 when the control link is selected. Further, the control link is to be passed to the name of the control signal to the transfer device 2 corresponding to the instruction, the URL associated with the control signal, or a CGI (Common Gateway Interface) program executed on the Web server 6. Includes an argument associated with the control signal appended to the URL. The correspondence relationship between the control link, the text character string, and the control signal is stored in advance in a storage device accessible from the Web server 6 such as the storage unit 43, for example.

  The control link includes, for example, a control link for operating the telephone function of the telephone terminal 4 such as hold and transfer, a control link for changing settings related to the operation of the transfer device 2 such as activation and stop of the transfer function, and transfer A control link for instructing the interruption or resumption of the operation currently being executed by the transfer device 2 can be considered, such as transfer rejection of the telephone in the middle.

  As described above, even when the transfer function of the transfer device 2 is not activated, the user of the transfer destination terminal 5 activates the web browser 13 by performing an operation via the input unit 16 and activates the web server 6. And the transfer device 2 can be remotely operated via a Web page provided by the Web server 6. At this time, although the terminal unique identifier of the transfer destination terminal 5 is included in the http request, it is notified by the transfer setting notification that the transfer function is not activated from the transfer device 2. In this case, the html document creation unit 41 creates an html document including a control link for activating the transfer function.

  In addition, the html document creation unit 41 may create the following html document.

(1) Information regarding transfer operations performed in the past. Various source information such as the telephone number of the transferred telephone, various names such as the subscriber name and company name of the telephone number, and the address and location of the subscriber and company. In this case, various names, addresses / locations, and other information related to the sender are stored in advance in a storage device that can be accessed by the html document creation unit 41, for example, the storage unit 43, in association with the telephone number of the sender. Since such information is generally managed in a customer database, the html document creation unit 41 may acquire information from a customer database prepared separately from the Web server 6.

(2) Information related to the result of operations such as a call, hold, transfer, transfer rejection, etc. performed via the transfer device 2. Date and time of incoming call, start and end date and time of call, hold time, forwarding phone number, etc. In this case, the control unit 30 of the transfer device 2 stores information on the time and time related to these operations in the storage unit 32 in association with the transmission source number and the transfer destination number. The html document creation unit 41 reads out the information from the storage unit 32 using, for example, the transmission source number as a key and writes it in the html document.

(3) A list of telephone numbers of senders set to transfer rejection. When there is an incoming call from the telephone number set for transfer rejection, the transfer device 2 does not transfer the incoming call even if the transfer function is activated. In this case, a list of telephone numbers set to transfer rejection is stored in the storage unit 32 by an operation by the telephone terminal 4 or a remote operation by the transfer destination terminal 5. Hereinafter, this list is referred to as a transfer rejection list. Prior to transfer execution, the control unit 30 determines whether or not the caller's number is registered in the transfer rejection list, and if applicable, does not transfer the incoming call even if the transfer unit 31 is active. . In response to an http request including a control link for referring to the transfer refusal list, the html document creation unit 41 makes an html document in which the transfer refusal list is described. Is transmitted from the http response transmission unit 42 to the transmission source of the http request.

  When the telephone number set for transfer rejection is described in the html document, it is preferable to write the control link for canceling the transfer rejection setting for the telephone number together with the telephone number set for transfer rejection. When receiving an http request indicating that the control link has been selected and inputted, the http request analysis unit 40 transmits a control command for canceling the transfer rejection setting for the telephone number to the transfer device 2. In response to this control command, the control unit 30 deletes the telephone number from the transfer rejection list in the storage unit 32.

(4) Setting status of transfer operation. Whether transfer operation is set. When the terminal unique identifiers of a plurality of mobile phone terminals are registered as the transfer destination terminal 5, it is conceivable to set the transfer operation individually for each terminal. The setting state of the transfer operation for each terminal at this time.

  Next, the operation of the telephone transfer system 1 will be described with reference to FIG. It is assumed that the transfer unit 31 of the transfer device 2 is activated in advance by an operation by the telephone terminal 4 or a remote operation via the Internet 8 by the transfer destination terminal 5. Assume that the transfer destination telephone terminal, that is, the telephone number of the transfer destination terminal 5 (hereinafter referred to as the transfer destination number) 090-5555-6666 is registered in advance in the storage unit 32 of the transfer apparatus 2. It is assumed that the telephone number (090-5555-6666) of the transfer destination terminal 5 and the terminal unique identifier (XYZ) are associated with each other and registered in advance in the storage unit 43 of the Web server 6. In the storage unit 11 of the transfer destination terminal 5, the terminal unique identifier (XYZ) of the own terminal, the telephone number (03-3333-4444) of the transfer device 2, and the URL (Uniform Resource Locator) of the Web page distributed by the Web server 6 are stored. Is registered in advance. Here, it is assumed that www.example.co.jp/XYZ.html is registered as the URL. The character string XYZ in the character string XYZ.html indicating the name of the html document corresponds to the terminal unique identifier XYZ. In this example, the terminal unique identifier is directly included in the URL, but may be included in the URL in the form of an argument.

  When the caller terminal 9 makes a call in a state where the caller number is notified and arrives at the transfer device 2 by line switching with a switch (not shown) of the PSTN 3, the caller terminal 9 provides a caller number notification service provided by the telecommunications carrier. The transfer device 2 is notified of 03-1111-2222, which is the telephone number of the subscriber terminal 9 (hereinafter referred to as the caller number) (step S1).

  Now, since the transfer unit 31 is activated in the transfer device 2, when the control unit 30 detects an incoming call, the transfer unit 31 makes a call to the transfer destination terminal 5 in a state of notifying the caller number, and the PSTN 3 Is transferred to the transfer destination terminal 5 while notifying 03-3333-4444, which is the telephone number of the transfer device 2 (hereinafter referred to as the transfer source number), by line switching in the exchange (not shown) (step S2).

  The control unit 30 notifies the Web server 6 that the call is sent to the transfer destination number 090-5555-6666 in order to transfer the incoming call from the caller number 03-3333-4444 along with the call to the transfer destination terminal 5. (Step S3). Receiving this notification, the Web server 6 associates the forwarding number and the caller number and stores them in the storage unit 43 (step S4).

  The transfer destination terminal 5 compares the telephone number of the transfer device 2 registered in advance in the storage unit 11 with the number notified by the caller ID notification service (step S5). 13 is started (step S6). In the Web browser 13, the http request generation unit 19 generates an http request including the terminal unique identifier of the own terminal and transmits it to the Web server 6 (step S7). If the comparison result in step S5 does not match, the transfer destination terminal 5 treats the incoming call as a normal incoming call.

  When receiving the http request, the Web server 6 analyzes the http request by the http request analyzing unit 40, and includes the terminal unique identifier of the terminal registered in advance in the storage unit 43 as the transfer destination terminal 5 in the http request. If it is included, the telephone number corresponding to the terminal unique identifier is read from the storage unit 43 (step S9). If it is determined in step S8 that the http request does not include the terminal unique identifier of the registered terminal, the Web server 6 ignores the http request or transmits an http response including an HTML document prepared in advance for the unregistered terminal. .

  Subsequently, the http request analysis unit 40 compares the number stored as the transfer destination number in the storage unit 43 in step S4 with the telephone number read in step S9, thereby obtaining the terminal-specific information acquired in step S7. When the telephone number of the telephone terminal having the identifier is used as the transfer destination number, it is determined whether or not there is a source number stored in association with the transfer number in step S4 (step S10). Thus, when it is found that the telephone number of the terminal of the transmission source of the http request is the transfer destination number and the transmission source number stored in association with the transfer destination number in step S4 is stored in the storage unit 43, The document creation unit 41 creates an html document (step S11).

  Note that the terminal unique identifier and the transfer destination number of the transfer destination terminal 5 may be associated with each other and stored in the storage unit 43 in advance. In this case, when the transfer destination number and the transmission source number are received from the transfer device 2 in step S4, it is determined whether or not the transfer destination number is stored in the storage unit 43, which corresponds to step S8. It is possible to determine whether or not the terminal is a registered terminal. Furthermore, the process corresponding to steps S9 and S10 may be completed by associating the terminal unique identifier and the caller number with the transfer destination number as an intermediary in step S4.

  At this time, the html document creation unit 41 creates an html document in which the transmission source number stored in the storage unit 43 in association with the transfer destination number is described in step S4. In addition to the source number or instead of the source number, information associated with the source number read from the customer database or the like may be described. Furthermore, a control link may be described.

  The http response transmission unit 42 transmits the html document to the transmission source of the http request received in step S7 (step S12).

  If they do not match in step S10, it is an http request from a terminal registered as a transfer destination terminal, but that terminal is not the terminal that the transfer device 2 is currently transferring. At this time, the http response transmission unit 42 transmits an html document stating that transfer is not being performed from the transfer device 2 to the transfer destination terminal 5 to the transmission source of the http request received in step S7. This html document may be stored in advance in the storage unit 43, or may be generated as appropriate by the html document creation unit 41. By reading this html document with the Web browser 13, the user of the transfer destination terminal 5 can make a call that is currently received from the transfer device 2 not for transfer but by a normal call from the telephone terminal 4. You can know that it is a thing.

  When the http response is received from the Web server 6, in the transfer destination terminal 5, the html document analysis unit 20 extracts the html document included in the http response, and the html document display unit 21 displays the extracted html document on the display unit 14. Displayed (step S13).

  An example of the screen displayed on the display unit 14 at this time is shown in FIG. In the address field 50, the URL designated by the http request transmitted in step S7 is described. In the main screen 51, a message 52 indicating that the call is a transfer call, a sender number field 53, a name field 54, an address field 55, and a control link field 56 are described in order from the top. The descriptions in the name column 54 and the address column 55 are information stored in advance in the customer database in association with the telephone number described in the caller number column 53. Each line of the control link column 56 is a control link, and the number at the beginning of the line indicates a dial number.

  Since the information of the sender number field 53, the name field 54, and the address field 55 is displayed on the display unit 14, the user of the transfer destination terminal 5 receives an incoming call from the transfer device 2 starting from step S2 from the telephone terminal 4. Knowing that the call is not a normal incoming call but a transfer call, and confirming the telephone number, name, address, etc. of the caller, the call can be started off-hook (step S14).

  Next, an operation when the transfer device 2 is remotely operated from the transfer destination terminal 9 will be described with reference to FIG. Here, the operation when the transfer device 2 activates the answering machine function unit 33 instead of responding to the transfer call by the user of the transfer destination terminal 9 who knows the call origination number of the transfer call by the operations of steps S1 to S13. explain.

  In step S11, the html document creation unit 41 includes a control link including a text message indicating the content of the remote operation and a command for instructing the Web server 6 to send a control signal to the transfer device 2, as shown in FIG. Assume that an html document has been created. The control signal is a signal for instructing an operation to be performed by the transfer device 2 in order to realize a target operation. Now, it is assumed that steps S1 to S13 have elapsed, but that no off-hook has been performed in step S14.

  At this time, an html document as shown in FIG. 6 is displayed on the display unit 14 of the transfer destination terminal 5 (step S20). When one of the numeric keys 1 to 9 is pressed at the input unit 16, the same control link as the one at which the number at the beginning of the line is pressed is selected from the control links described in the control link field 56 (step S21). In response to this pressing, the http request generation unit 13 generates an http request including the selected control link and transmits it to the Web server 6 (step S22). Here, it is assumed that the user presses the numeric key “2” in order to activate the answering machine function of the transfer device 2.

  In the Web server 6, after analyzing the http request received by the http request analysis unit 40 and extracting the control link, a control signal corresponding to the control link is transmitted to the transfer device 2 (steps S23 and S24) and a predetermined number An http response is returned to the transfer destination terminal 5 (step S25).

  When receiving the control signal, the control unit 30 of the transfer apparatus 2 performs an operation according to the control signal. A control signal corresponding to the control link pressed in step S21 is transmitted, and the transfer device 2 performs an operation corresponding to the control signal. Here, in response to the depression of the numeric key “2” “activate answering machine”, the control unit 30 activates the answering machine function unit 33 (step S26). Accordingly, the transfer unit 31 stops the transmission to the transfer destination terminal 5 continued from step S2 in FIG. 5 (step S27).

  The answering machine function unit 33 establishes a call in response to the incoming call from the caller terminal 9 continuing from step S1 in FIG. The voice message transmitted by the user of the caller terminal 9 is stored as voice data in the storage device (step S30).

  In the above description, the transfer destination terminal 5 activates the Web browser 13 in response to an incoming call from the transfer device 2. However, even when there is no incoming call from the transfer device 2, the user performs the operation using the input unit 16. The web browser 13 may be activated according to the operation, and the operations after step S6 may be performed. In this case, the html document creation unit 41 creates an html document including only the control link field 56.

  In particular, the control link column 56 preferably describes a control link for activating the transfer function. In the control link column 56 of FIG. 6, “3. Activation / deactivation of transfer telephone” corresponds to this control link. When the numeric key “3” is pressed while the html document of FIG. 6 is displayed on the display unit 14, the Web server 6 sends a control signal for requesting activation of the transfer unit 31 to the transfer device 2. By using such a control link, even if the user of the transfer destination terminal 5 goes out without starting the transfer function of the transfer device 2, it can be started from the outside.

  The telephone transfer system 1 is an embodiment of the present invention, and various modifications are conceivable. FIG. 8 shows a telephone exchange system 60 which is an example of a modification. The difference from the telephone transfer system 1 is that the main apparatus 62 of the private branch exchange system 61 is used instead of the transfer apparatus 2, and a plurality of extension telephone terminals 4a, 4b,..., 4n corresponding to the telephone terminal 4 (n is a natural number) Exists. The extension telephone terminals 4a, 4b,..., 4n are assigned IDs = 1, 2,..., N as unique identifiers (n is a natural number). The telephone exchange system 60 generally operates as follows.

(1) The caller terminal notifies the caller number and makes a call to the telephone number 03-3333-4444.

(2) The main unit rings each extension telephone terminal. At this time, the extension telephone terminal (ID = 1) for which forwarding has been set in advance is not ringed, but instead, the incoming call is forwarded to the telephone number 090-5555-6666 registered in advance in association with ID = 1. To do.

(3) In response to the incoming call, the transfer destination terminal 5 activates the Web browser 13. The Web browser 13 notifies the terminal unique identifier XYZ of the terminal itself to the address under the Web server 6.

(4) The Web server 6 identifies the incoming call currently being transferred to the transfer destination terminal 5 having the notified terminal unique identifier, and generates an html document in which the caller number of the incoming call is 03-1111-2222 Then, the data is transmitted to the transfer destination terminal 5. The web browser 13 displays the html document.

  FIG. 9 shows a telephone transfer system 70 which is another modified example. In the telephone transfer system 1, the transfer device 2 and the Web server 6 are connected without going through another device. On the other hand, in the telephone transfer system 70, the Web server 6 is disposed on the Internet 8, and the transfer device 71 and the Web server 6 are connected via the Internet 8. In order to take such a connection form, the transfer device 71 includes a LAN (Local Area Network) card and is configured to be connected to the Internet 8.

  As mentioned above, although this invention was demonstrated according to embodiment, the above-mentioned embodiment and its deformation | transformation are illustrations, and this invention is not limited to these.
