  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

<First Embodiment>
FIG. 1 is a diagram showing a schematic configuration of a communication system according to a first embodiment of the present invention. The illustrated communication system includes a terminal A1 and a terminal B2. The terminal A1 and the terminal B2 are communication terminals (for example, a smart phone, a PC, a mobile phone, etc.) equipped with both a telephone function (call) and a data communication function (Internet connection, etc.).

  In the illustrated example, the terminal A1 makes a telephone connection to the terminal B2 via the first network 3 (for example, 3G, NGN, etc.) (S11). Then, the terminal A1 transmits the IP address information (address information) of the terminal A1 itself to the terminal B2 via the first network 3 (S12). The terminal B2 transmits a connection request addressed to the IP address information received from the terminal A1 to the terminal A1 via the second network 4 (for example, the Internet), and the terminal B2 transmits the connection request between the terminal A1 and the terminal B2. 2 starts data communication via the network 4 (S13).

  FIG. 2 is a diagram for specifically explaining the configuration and operation of the communication system shown in FIG.

  The terminal A1 and the terminal B2 are assumed to be connected via the first network 3 and the second network 4. In the present embodiment, the first network 3 is a telephone network, and here, 3G (3rd Generation: third generation mobile phone) and NGN (Next Generation Network) are used. The second network 4 is a network to which an unspecified number of users can connect and can perform data communication. Here, the Internet is used.

  The terminal A1 includes a telephone function unit 11, an IVR function unit 12, an address acquisition function unit 13, and a data communication function unit 14. The telephone function unit 11 is connected to the other apparatus by line switching via the first network 3 and performs a telephone call by voice. The IVR function unit 12 converts data into a voice DTMF signal and also converts the DTMF signal into data. The DTMF (Dual-Tone Multi-Frequency) signal is composed of 16 kinds of codes, a number from 0 to 9, and symbols of *, #, A, B, C, and D. This is a method of transmitting with a synthesized signal sound of a frequency band, and is also called “tone signal”, “dial tone”, or “push signal”. The address acquisition function unit 13 inquires and acquires its own IP address information. The data communication function unit 14 performs data communication by packet communication via the second network 4.

  The terminal B2 also includes a telephone function unit 21, an IVR function unit 22, an address acquisition function unit 23, and a data communication function unit 24 similar to those of the terminal A1.

  For the terminal A1 and the terminal B2 described above, for example, a general-purpose computer system including a CPU, a memory, an external storage device such as an HDD, an input device, and an output device can be used. In this computer system, the functions of the terminal A1 and the terminal B2 are realized by the CPU executing programs for the terminal A1 and the terminal B2 loaded on the memory. The programs for the terminal A1 and the terminal B2 can be stored in a computer-readable recording medium such as a hard disk, a flexible disk, a CD-ROM, an MO, and a DVD-ROM, or can be distributed via a network.

  Next, the operation of the connection method of this embodiment will be described.

  As shown in FIG. 2, first, the telephone function unit 11 of the terminal A receives a user operation / instruction, and makes a call to the terminal B via the first network 3 (S21). It is assumed that terminal A (user) does not know the IP address information of terminal B, but has acquired the telephone number of terminal B. The NGN of the first network 3 performs line authentication of the terminal A, and if the line authentication is successful (in the case of a call from a valid contractor), the telephone call of the terminal A is connected to the terminal B, and the line If the authentication fails (in the case of an outgoing call from an unauthorized contractor), the telephone call of terminal A is not connected to terminal B.

  When the telephone function unit 21 of the terminal B receives a telephone call from the terminal A that has succeeded in the line authentication (S22), it transmits a response signal to the terminal A (S23).

  When the telephone function unit 11 of the terminal A receives the response signal in S23, the telephone function unit 11 notifies the address acquisition function unit 13. In response to the notification from the telephone function unit 21, the address acquisition function unit 13 inquires the data communication function unit 14 about the IP address information for data communication of the terminal A itself (S24). Then, the address acquisition function unit 13 acquires its own IP address information from the data communication function unit 14 (S25), and transfers it to the IVR function unit 12 (S26). The IVR function unit 12 converts the IP address information into a DTMF signal and delivers it as voice information to the telephone function unit 11 (S27). The telephone function unit 11 transmits the DTMF signal (IP address information) received from the IVR function unit 12 to the terminal B side via the first network 3 (S28).

  The telephone function unit 21 of the terminal B receives the DTMF signal as voice information and transfers the received DTMF signal to the IVR function unit 22 (S29). The IVR function unit 22 converts the DTMF signal into data, and passes it to the data communication function unit 24 as IP address information (S30). The data communication function unit 24 connects to the terminal A (for example, connection using the http protocol) with the received IP address information as the destination via the second network 4 (S31). As a result, communication via the second network 4 is started between the data communication function unit 14 of the terminal A and the data communication function unit 24 of the terminal B.

  As described above, in this embodiment, even if the IP address information of the communication partner is not known in advance, it is possible to connect to the partner device using the telephone number, and the IP address that may change dynamically is always set. There is no need to notify. In addition, there is no need to disclose unique information called an IP address to an unspecified number of people, and safety is improved.

  In the present embodiment, line switching is used for connection via the first network 3 by the telephone function units 11 and 21. However, in addition to circuit switching, SIP protocol (Session Initiation Protocol) is used. A telephone connection (IP phone) or the like may be used. In telephone connection using the SIP protocol, line authentication similar to that of a normal telephone line is performed by the SIP server. In this case, a packet network (for example, 3G / LTE (3GPP Long Term Evolution) and NGN) is used for the first network 3. This makes it possible to apply this technology regardless of network type, such as ordinary analog or digital fixed telephone lines (fixed telephone lines / optical telephone lines / IP telephone lines, etc.), mobile phone lines (3G / LTE, etc.) it can.

<Second Embodiment>
FIG. 3 is a diagram illustrating the configuration and operation of a communication system according to the second embodiment of this invention. In the present embodiment, the terminal B2 on the receiving side that has received a call from the terminal A1 notifies the terminal A1 of its own IP address information.

  The communication system shown in the figure has a terminal A1 and a terminal B2, and is connected via a first network 3 and a second network 4. The first network 3 and the second network 4 of this embodiment are the same as those of the first embodiment.

  Similarly to the first embodiment, the terminal A1 and the terminal B2 are the telephone function units 11 and 21, the IVR function units 12 and 22, the address acquisition function units 13 and 23, and the data communication function units 14 and 24, respectively. With.

  In the operation of the present embodiment, as shown in FIG. 3, first, the telephone function unit 11 of the terminal A accepts a user operation / instruction and makes a call to the terminal B via the first network 3 ( S41). It is assumed that terminal A (user) does not know the IP address information of terminal B, but has acquired the telephone number of terminal B. The NGN of the first network 3 performs line authentication of the terminal A, and if the line authentication is successful (in the case of a call from a valid contractor), the telephone call of the terminal A is connected to the terminal B, and the line If the authentication fails (in the case of an outgoing call from an unauthorized contractor), the telephone call of terminal A is not connected to terminal B.

  When the telephone function unit 21 of the terminal B receives a telephone call from the terminal A that has succeeded in line authentication (S42), the telephone function unit 21 transmits a response signal to the terminal A (S43) and notifies the address acquisition function unit 23 of the incoming call. . In response to the notification from the telephone function unit 21, the address acquisition function unit 23 inquires of the data communication function unit 24 about IP address information for data communication of the terminal B itself (S44). Then, the address acquisition function unit 23 acquires its own IP address information from the data communication function unit 24 (S45), and transfers it to the IVR function unit 22 (S46). The IVR function unit 22 converts the IP address information into a DTMF signal and delivers it as voice information to the telephone function unit 21 (S47). The telephone function unit 21 transmits the DTMF signal (IP address information) received from the IVR function unit 22 to the terminal A side via the first network 3 (S48).

  The telephone function unit 11 of the terminal A receives the DTMF signal as voice information and passes the received DTMF signal to the IVR function unit 12 (S49). The IVR function unit 22 converts the DTMF signal into data, and passes it to the data communication function unit 14 as IP address information (S50). The data communication function unit 14 connects to the terminal B (for example, connection using the http protocol) with the received IP address information as the destination via the second network 4 (S51). As a result, communication via the second network 4 is started between the data communication function unit 14 of the terminal A and the data communication function unit 24 of the terminal B.

  As described above, in this embodiment, even if the IP address information of the communication partner is not known in advance, it is possible to connect to the partner device using the telephone number, and the IP address that may change dynamically is always set. There is no need to notify. In addition, there is no need to disclose unique information called an IP address to an unspecified number of people, and safety is improved.

  In this embodiment, line switching is used for connection via the first network 3 by the telephone function units 11 and 21, but telephone connection (IP telephone) using the SIP protocol is used in addition to circuit switching. It is good as well. In telephone connection using the SIP protocol, line authentication similar to that of a normal telephone line is performed by the SIP server. In this case, a packet network (for example, 3G / LTE and NGN) is used for the first network 3. This makes it possible to apply this technology regardless of network type, such as ordinary analog or digital fixed telephone lines (fixed telephone lines / optical telephone lines / IP telephone lines, etc.), mobile phone lines (3G / LTE, etc.) it can.
