The storage unit 22 forms administrator terminal identification information registration means in the present invention.

  In this embodiment, a maximum of four mobile terminal IDs can be registered as these administrator mobile terminals, and not only the administrator's mobile phone 1 but also a person related to the administrator, for example, a family The mobile terminal ID of the mobile phone 1 can also be registered as an administrator mobile terminal.

  In addition, the communication unit 24 in the AP terminal 2 of the present embodiment uses the same communication method as that for connecting the computers 4 and 5 to the ADSL modem router 3, for example, an ADSL modem router in the IEEE 802.3u standard communication method. However, the present invention is not limited to this, and the communication method between the communication unit 24 and the ADSL modem router 3 is sufficient to send and receive VoIP packets. As long as a sufficient communication speed can be obtained, wireless or infrared contactless communication may be used as long as the sufficient communication speed can be obtained.

  When registering a mobile terminal ID as an administrator mobile terminal, the registration button 28 may be operated with the mobile phone 1 to be registered placed in the vicinity of the AP terminal 2, and the registration button 28 is operated. Thus, when the four mobile terminal IDs are not already registered (stored) in the storage unit 22, the mobile terminal ID of the mobile phone 1 is acquired by the wireless data communication in the AP terminal 2 and the liquid crystal panel (LCD) ) And a pseudo incoming call request is transmitted from the AP terminal 2 to the mobile phone 1 having the mobile terminal ID displayed on the liquid crystal panel (LCD) 25. Since the incoming call notification is performed at 1, the registration button 28 is operated again when the mobile phone on which the incoming call notification is performed is the mobile phone 1 that is definitely to be registered. And the portable terminal ID, which is displayed on the liquid crystal panel (LCD) 25 at that time is stored (registered) in the storage unit 22.

  The wireless LAN module 23 used in the AP terminal 2 of this embodiment is a part that performs data communication with the mobile phone 1 by the spread spectrum communication method in the 2.4 GHz band that is the ISM band. As 23, a wireless LAN standard conforming to IEEE802.11b or IEEE802.11g can be suitably used.

  Further, the control unit 21 used in the AP terminal 2 of the present embodiment transmits and receives various data such as VoIP packets to and from the wireless LAN module 23 of the mobile phone 1 via the wireless LAN module 23. The VoIP call is made possible by a control microcomputer (MPU).

  Hereinafter, the operation content of the AP terminal 2 in the VoIP call system of the present embodiment will be described based on the flowchart of FIG. In the connection control server 13, the modem ID of the ADSL modem router 3 is registered in advance, and the ADSL modem router 3 is always connected to each ISP 10a, 10b,. It is assumed that the portable terminal ID of the administrator portable terminal is registered by performing the above registration operation.

  First, as shown in the flowchart of FIG. 4, the control unit 21 of the AP terminal 2 is located within the communicable range (cell) of the wireless LAN module 23, that is, a call packet from the mobile phone 1 in the area. Waiting to receive data.

  In this state, when call packet data is transmitted from the mobile phone 1, reception of the transmitted call packet data is detected in step S1, and the process proceeds to step S2. ID collation processing is performed.

  In this administrator terminal ID collation process, first, the portable terminal ID of the portable telephone 1 included in the received call packet data is the portable terminal ID of the administrator portable terminal registered (stored) in the storage unit 22. It is checked whether or not it matches.

  If the mobile terminal IDs match in the collation, that is, if the mobile phone 1 that is the transmission source of the call packet data is an administrator mobile terminal, the steps of S8 to S7 are not carried out. In step S2, the call packet transmission process is performed without performing the normal portable terminal ID authentication process or the call availability determination based on the traffic information. On the other hand, the collation result in step S2 does not match the portable terminal ID. That is, if the mobile phone 1 that is the transmission source of the call packet data is not an administrator mobile terminal, the process proceeds to step S4, and terminal ID authentication processing is performed.

  Specifically, in the terminal ID authentication process in step S4 of the present embodiment, the mobile terminal included in the call packet data received from the mobile phone 1 with respect to the connection control server 13 assigned with a predetermined IP address. An authentication request including the ID and the AP terminal ID of the AP terminal 2 is transmitted.

  In response to the reception of this authentication request, the connection control server 13, as described above, of the mobile phone 1 in which the mobile terminal ID included in the received authentication request is registered as the mobile phone 1 that permits the call. Whether or not it is a mobile terminal ID, that is, whether or not the mobile terminal ID is registered is searched. If it exists, an authentication result of “authentication OK” is returned, and if it does not exist, “authentication NG” is returned. ”Is returned.

  In response to the reception of the authentication result returned from the connection control server 13 in this way, the control unit 21 determines “No” in step S5 when the received authentication result is “authentication NG”. Then, by terminating the process and returning to S1, the VoIP call is not permitted by not performing the call packet transmission process of S8 based on the received call packet data, while the received authentication result is “ If “authentication is OK”, “Yes” is determined in step S5 and the process proceeds to step S6, where traffic information indicating the traffic status of the ADSL line at that time is acquired from the ADSL modem router 3. Implement traffic information acquisition processing.

  Specifically, in the traffic information acquisition process, the control unit 21 transmits a traffic information output request to the connected ADSL modem router 3.

  In response to the traffic information output request, the ADSL modem router 3 returns the traffic information of the ADSL line at that time to the AP terminal 2 that is the transmission source of the traffic information output request.

  Then, in response to the return of the traffic information, the control unit 21 determines whether or not the traffic status of the ADSL line specified from the returned traffic information is a traffic status exceeding a predetermined data amount. The determination is made in the step.

  In the determination in step S7, if the traffic status of the ADSL line is a result of determination that the traffic status is greater than or equal to a predetermined amount of data, that is, “Yes” is determined in step S7. In this case, the process is terminated and the process returns to S1, so that the call packet transmission process of S8 based on the received call packet data is not performed, so that the VoIP call is not permitted, while the traffic state of the ADSL line Is a result of determination that the traffic is not more than a predetermined amount of data, that is, if “No” is determined in the step of S7, the process proceeds to the step of S8 and the call packet transmission process is performed. To do.

  In the call packet transmission process, the call packet data received from the mobile phone 1 is transmitted (relayed) to the call control server 11 to which a predetermined IP address is assigned, and then the process proceeds to step S9. The process proceeds to a connection packet relay process for relaying a connection packet accompanying the transmission of the call packet (S9).

  Then, in response to the reception of the call packet data relayed in the call packet transmission process in step S8, the call control server 11 receives the telephone number (VoIP telephone number) of the call partner included in the received call packet. The global IP address corresponding to is specified, and the call request is relayed to the specified global IP address. In this embodiment, SIP (Session Initiation Protocol) is used for the call control, but the present invention is not limited to this, and the protocol used for the call control is appropriately selected. That's fine.

  When the global IP address cannot be specified, for example, when the call destination telephone number is not registered, the call control server 11 returns a call error (connection packet) and performs the processing. To return to S1.

  In response to the transmission of the call request, the other party's telephone, for example, the mobile phone 1 is notified of the incoming call by a ringing tone or a vibrator. When the user performs an incoming call operation, for example, a call button on the mobile phone 1 (the other party) that is calling, the mobile phone 1 (the other party) sends a response indicating that the call has been successful. Is transmitted to the call control server 11, and in response to this response, the call control server 11 sends the success response (connection packet) including the global IP address of the mobile phone 1 (the other party) that is the call destination to the caller. A reply is made to the mobile phone 1.

  Whether this successful response (connection packet) or paging error (connection packet) is relayed to the mobile phone 1 (calling source) in the connection packet relay process of S9, and whether the connection has been established by the contents of the connection packet. No is determined in step S10.

  If the relayed connection packet is a paging error, it is determined as “No” in step S10, and the process ends and returns to S1, so that the VoIP call is not started, but the relayed connection packet is successful. If it is a response, it is determined as “Yes” in the step of S10, and the VoIP call is started by proceeding to the VoIP packet relay processing of the step of S11 for relaying the VoIP packet data transmitted from the respective mobile phones 1. Is done.

  When the VoIP call based on the VoIP packet relay process is terminated, specifically, when a specific call end packet data indicating the end of the call is transmitted to the call control server 11, the call end packet The connection end due to the data transmission is detected in step S12, and the process proceeds to step S13. The mobile terminal ID, the AP terminal ID, the VoIP call start time and end time of the mobile phone 1 on which these VoIP calls are made, The connection information transmission process for transmitting the connection information including “” to the connection control server 13 is performed, the series of processes is terminated, and the process returns to the step S1 again.

  As described above, according to the present embodiment, an access point is simply installed by connecting the AP terminal 2 to the ADSL modem router 3 which is an always-connected communication terminal already installed in a general house or the like. Therefore, the chance that the user of the mobile phone 1 (mobile terminal) can use the VoIP call can be remarkably increased, and the convenience of these users can be improved.

  Further, according to the present embodiment, a mobile terminal having a predetermined mobile terminal ID (terminal identification information) permitted to be connected in advance, that is, a mobile terminal ID is registered in the connection control server 13 by subscribing to the VoIP connection service. Since all of the mobile terminals that are set up are allowed to establish a VoIP call connection, it is possible to prevent these AP terminals 2 (VoIP call wireless access point terminals) from being illegally connected and used.

  Further, according to the present embodiment, the connection control server 13 (connection management server) can manage the connection information including the mobile terminal ID (terminal identification information). A corresponding fee or the like can also be calculated.

  Further, according to the present embodiment, when the traffic state on the ADSL line (always connected line) is equal to or greater than a predetermined data communication amount, the VoIP call is started by transmitting the call packet data. Therefore, it is possible to avoid an adverse effect such as a decrease in processing due to data waiting or the like on the data communication other than the VoIP call, that is, the data communication of the personal computers 4 and 5 due to traffic tightness.

  In addition, according to the present embodiment, the administrator or the related person of the administrator registers the administrator portable terminal ID (terminal identification information of the administrator portable terminal), so that the traffic state in the ADSL line (always connected line) Regardless of the case, a VoIP call can always be performed.
