  Note that the switching function of the MDF 43 is, for example, a program step executed by the CPU of the relay device 40.
  The other input / output port of the ADSL modem 42 is connected to one input / output port of the VoIP gateway 45. The other input / output port of the VoIP gateway 45 is connected to the provider 50 through a dedicated line (a line for VoIP communication) such as an optical fiber cable.
[0016]
  For example, a fixed telephone 90 is connected to the telephone line network 31.
  On the other hand, the provider 50 connected to the VoIP gateway 45 is connected to the Internet 60. The Internet 60 is connected to a provider 55 and other devices (not shown) that transmit and receive information via the Internet 60.
  Further, for example, the gateway 72 of the processing device 70 of the calling proxy system is connected to the Internet 60 via the provider 55. The processing device 70 is provided with a plurality of proxy call mobile phones. For example, the call proxy mobile phone 71 performs a call to the destination mobile phone 80 that has made a call with the fixed telephone 10 of the call originator.
  In FIG. 1, only one source fixed telephone 10 having the source interface 20 is shown, but an appropriate number can be provided.
  If the providers 50 and 55 are unnecessary, they may be omitted.
  The dedicated line between the relay device 40 and the provider 50 is arbitrary. It does not have to be an optical fiber cable.
  Also, the line between the processing device 70 and the Internet 60 is arbitrary.
  The processing device 70 and the Internet 60 may be connected via a commercial service provider.
  In addition, the access line from the source interface 20 to the relay device 40 may use other communication methods instead of ADSL communication using a telephone line. For example, an ISDN line may be used.

[0017]
  Next, the operation of the transmission agent system according to the first embodiment will be described.
  For example, when the telephone number (for example, 090-1234-5678) of the destination mobile phone 80 is input using a dial key provided on the fixed phone 10, the source fixed phone 10 The telephone number (090-1234-5678) of the mobile phone 80 is transmitted to the caller interface 20 ((1) in FIG. 1). When it is determined that the switching means 21 of the caller interface 20 is a call to a mobile phone (for example, the first three digits of the destination telephone number are “090”), the input / output port 21b of the switching means 21 1 transmits the telephone number (090-1234-5678) of the destination mobile phone 80 to the ADSL modem 22 ((2) in FIG. 1). The ADSL modem 22 converts the telephone number (052-987-6543) of the source fixed telephone 10 and the telephone number (090-1234-5678) of the destination mobile telephone 80 into digital data signals of the ADSL communication system. To the input / output port 23b of the splitter 23 ((3) in FIG. 1). The splitter 23 includes the telephone number (052-987-6543) of the source fixed telephone 10 input to the input / output port 23b, the telephone number (090-1234-5678) of the destination mobile telephone 80, and the processing device. 70 address information is transmitted to the relay device 40 provided in the telephone station via the telephone line network 30 by the ADSL communication method ((4) in FIGS. 1 and 2).
[0018]
  When the MDF 43 of the relay device 40 receives an analog signal such as a voice signal or an ADSL signal from the source interface 20 of the user A's home via the telephone line network 30, it determines that the signal is from a contractor of ADSL communication. To the splitter 41 ((5) in FIG. 2).
  The splitter 41 separates an analog signal such as an audio signal and an ADSL signal. In the present embodiment, an ADSL signal is transmitted from the transmission source interface 20 (the telephone number of the fixed telephone 10 that is the transmission source, the telephone number of the mobile phone 80 that is the reception destination, and the address information of the processing device 70). Therefore, the ADSL signal is transmitted to the ADSL modem 42 ((6) in FIG. 2).
  As described above, if the data transmitted from the transmission source interface 20 is an ADSL signal (when a call is made to the mobile phone using the fixed telephone 10 of the transmission source at the user A's home and transmission from the PC 11), The ADSL signal is transmitted to the ADSL modem 42. On the other hand, if the data transmitted from the caller interface 20 is an analog signal (when a call is made to a telephone other than a mobile phone using the caller's fixed telephone 10 at the user A's home), the analog signal is sent to the splitter 41. And is transmitted to the exchange 44.
  When receiving the ADSL signal, the ADSL modem 42 transmits the ADSL signal to the VoIP gateway 45 ((7) in FIG. 2).
[0019]
  In the VoIP gateway 45, the ADSL signal is converted into a LAN signal for communication of the Internet 60 (the telephone number of the source fixed telephone 10, the telephone number of the destination mobile telephone 80, and the address information of the processing device 70). , And transmitted to the provider 50 via a VoIP dedicated line (for example, an optical fiber cable). The provider 50 transmits the LAN signal to the VoIP gateway 72 of the processing device 70 via the Internet 60 and the provider 55 based on the address information of the processing device 70 included in the LAN signal ((8) in FIG. 2). .
  Since the LAN signal includes the telephone number (090-1234-5678) of the destination mobile phone 80, when the processing device 70 receives the LAN signal, the processing device 70 receives the destination telephone number via the calling proxy mobile phone 71. A calling signal is transmitted to the mobile phone 80. What kind of processing is performed in the processing device 70 to perform the calling proxy using the calling proxy mobile phone 71 is arbitrary.
[0020]
  When receiving the call signal, the destination mobile phone 80 notifies the user of the mobile phone 80 of the incoming call, for example, with a ring tone. When the user of the mobile phone 80 operates, for example, a call key (not shown) of the mobile phone 80, the processing device 70 provided with the calling proxy mobile phone 71, the provider 55, the Internet 60, the provider 50, and the relay device 40. The mobile phone 80 that is the destination and the fixed telephone 10 that is the call destination are connected via the telephone line network 30 (ADSL communication) and the call source interface 20 so that the call can be made.
  In this way, the user of the source fixed telephone 10 can make a call with the user of the destination mobile phone 80.
  In the processing device 70, a transmission agent company that performs a predetermined billing process and manages the transmission agent system issues, for example, a fee bill to the user of the fixed telephone 10 as a transmission source every predetermined period.
  According to the first embodiment, since data is transmitted and received via the Internet 60, there is no need to install the processing device 70 in various places, and even if the processing device 70 is out of the city, an expensive long distance call Since there is no need to charge a fee, the operation cost of the transmission agent system can be reduced. Moreover, the installation cost can be reduced.
[0021]
  On the other hand, when the fixed telephone 10 of the caller makes a call to the fixed telephone 90, the switching means 21 of the caller interface 20 determines that it is not a call to the mobile phone, and the switching means 21 is turned on. An analog signal such as an audio signal is transmitted from the output port 21 a to the splitter 23. The analog signal is transmitted to the relay device 40 via the telephone line network 30. The analog signal is separated from the ADSL signal by the splitter 41 of the relay device 40 and transmitted to the exchange 44. When receiving the analog signal, the exchange 44 analyzes the telephone number information, performs a circuit switching operation, and connects to the destination fixed telephone 90 via the telephone network 31.
  Thus, when the source fixed telephone 10 calls the fixed telephone 90, the source fixed telephone 10 and the fixed telephone 90 are connected by a data transmission method using an analog signal of the telephone line network. A call can be made.
  In addition, when users B and C who do not have an ADSL communication contract make a call to the fixed telephone 90, an analog signal such as voice is transmitted from the MDF 42 of the relay station 40 of the telephone office to the analog signal of the subscriber of ADSL communication or ADSL. It is separated from the signal and transmitted to the exchange 44 as it is.
  Note that the relay device 40 as a whole only needs to have a function of converting a received signal (for example, an ADSL signal) into a signal (for example, a LAN signal) for realizing a voice call on the IP network. . Therefore, the configuration of the relay device 40 is not limited to the first embodiment. In the first embodiment, a case has been described in which the VoIP gateway 45 has a function of converting an ADSL signal into a LAN signal and the ADSL modem 42 passes an ADSL signal transmitted from the user A side. (In this case, the ADSL modem 42 is not an essential component requirement). However, for example, when the ADSL modem 42 has a function of converting an ADSL signal into a LAN signal, the VoIP gateway 45 may not be provided. In this case, a router (not shown) may be provided at the position of the VoIP gateway 45. The router here is a device that connects between networks or lines that match a protocol of a predetermined layer (for example, layer 4) or more of an intersystem interconnection standard (for example, OSI).

  The configuration and operation of the present invention are not limited to the first and second embodiments.
  Further, although the telephone numbers of the fixed telephones 10 and 210 of the transmission source are transmitted as identification information for specifying the transmission source from the transmission source interfaces 20 and 220, the ID number of the transmission source may be transmitted. Moreover, you may transmit both.
  Further, the method of determining that the user of the source fixed telephone 10 has called the mobile phone is not limited to the method of determining that the first three digits of the destination telephone number are “090”. Various methods are conceivable.
  In addition, the caller telephone may not be a fixed telephone. Further, the destination telephone does not have to be a mobile phone.
  The means for data transmission / reception between the relay device 40 and the transmission source interface 20 is not limited to ADSL communication using a telephone line.
  In addition, as shown in FIG. 3, when it is not appropriate for the processing device 70 designated by the transmission source interface 20 to perform the transmission agent, another processing device connected to the Internet 60 is substituted for the transmission agent. May be. Here, the case where it is not appropriate to perform the calling agent may be, for example, the case where all of the calling agent mobile phones provided in the processing device 70 are in use. In such a case, since the processing device 70 cannot perform the outgoing call proxy operation, the processing device 70 instructs the processing device 70b to substitute the outgoing call proxy operation to fix the telephone number of the destination mobile phone 80 and the source. The telephone number of the telephone 10 is transmitted. The calling proxy mobile phone 71b of the processing device 70b transmits a call signal to the destination mobile phone 80. In this way, by connecting the processing devices 70 via the Internet 60, even if calling signals from a large number of sender telephones to a destination mobile phone are concentrated on one processing device, the other processing devices 70a to 70- Since c can be substituted for the call proxy operation, the call proxy operation can be performed more efficiently. The processing device 70 may not be replaced with another processing device when the processing device 70 is not capable of performing a call proxy operation. For example, there may be a management device that manages a plurality of processing devices connected to the Internet 60, and the transmission agent operation may be assigned to each processing device so that the transmission agent operation can be performed efficiently. According to this, when call requests for mobile phones are concentrated on an arbitrary processing device, the call origination system as a whole can respond to the call requests.
  In the first and second embodiments, the source interfaces 20 and 220 are the telephone numbers of the source fixed telephones 10 and 210, the telephone numbers of the destination mobile phones 80 and 280, and the processing devices 70 and 270, respectively. Address information at a time ((4) shown in FIGS. 1 and 2, (3) shown in FIG. 4). However, if it is confirmed that the source interfaces 20 and 220 and the processing devices 70 and 270 can be connected, the telephone numbers of the fixed telephones 10 and 210 of the source and the telephone numbers of the mobile phones 80 and 280 of the destination are transmitted. You may make it do.
  Each communication means may be wired or wireless.
