In a telephone conference, first, when a call is made between two parties via an IP network, when a third party calls one of the former two parties via the IP network, the third Is in a call state including the caller. Further, the same is true even if a telephone call is made from a subsequent fourth party. The process of confirming the participation of the third party or later is performed by using two or more voice data other than the user's own voice received via the IP network from another telephone connected to the same type of telephone equipment adapter. And performs audio output. For example, to the caller of the telephone 10, the voice of the telephones 20 and 30 mixed by the voice data mixing means 700 of the telephone adapter 12 is output.

In this embodiment, the voice data mixing means 700 is provided in the communication device adapter. However, as another mode, the voice data mixing means 700 having the voice data mixing means 700 is provided.
A configuration is also possible in which one device mixes and transmits voice data of another participant excluding its own uttered voice to another communication device adapter device. In this case, it is not necessary to provide the audio data mixing means 700 in another communication device adapter.

In the procedure for confirming participation in the telephone conference described above, first, it is a procedure for confirming whether or not a third or later party participates in a telephone call between two parties. No action was taken in this procedure to confirm that the call was allowed to participate in a conference call conducted by three or more parties. However, if the call between the three parties is a mere notification of information or a conversation of the level of a small talk, it is not necessary to confirm whether the participating parties are authorized parties, but hold a conference. It is necessary to confirm whether the call is permitted to participate in the call. For this reason, in the third embodiment, in order to confirm whether or not the person is permitted to participate in the call, an identification number is assigned to the conference, and the caller is given one of the permission information before starting the call. A method for allowing a certain conference identification number to be entered and determining that the entered identification number is correct. How to confirm that the phone is authorized to participate in the phone, and to enter another password, which is another permission information, before starting a call, and confirm that the entered password is the correct password A method is conceivable. 3 above
The two methods will be described below one by one.

First, a method of setting an identification number for a telephone conference will be described. An identification number is set for each telephone conference, and the set identification number is stored in advance in the permission information storage unit 855. However, the identification number of the telephone conference is stored not in all of the permission information storage units 855 provided in the telephone adapter connected to the telephone set participating in the telephone conference, but in the organizer of the telephone conference. Is stored only in the permission information storage unit 855 of the telephone device adapter connected to the telephone set. The telephone adapter connected to the organizer's telephone determines whether or not the person can participate in the telephone conference. The IP network communication processing means 5000 of the host device's communication device adapter includes the IP network 14
When there is a further call request, the telephone conference identification number management means 80
0 is notified that there is a call request. Upon receiving the notification, the telephone conference identification number management means 800 notifies the telephone requesting the telephone of a message prompting the input of the telephone conference identification number by voice data. Then, when the identification number of the telephone conference is input from the telephone of the called party, IP network communication processing means 5000 receives the identification number and notifies received telephone identification number to telephone conference identification number management means 800. I do. Teleconference identification number management means 8
00 refers to the permission information storage unit 855 and checks whether the notified conference call identification number is the set identification number. If it is the set identification number, the telephone conference identification number management unit 800 outputs a message for permitting the call via the IP network communication processing unit 5000. The message permitting the call is a message that the other party can hear by voice. If the notified conference call identification number is a number not set in the permission information storage unit 855, a message not permitting participation in the telephone conference is sent to the telephone conference identification number management unit 800.
Output to the destination telephone via the IP network communication processing means 5000. This message is also a message that can be heard by the caller of the other party's telephone by voice.

Next, a method for confirming that it is possible to participate in a telephone conference by using the telephone identification number will be described. The identification numbers of the telephones that can participate in the telephone conference are stored in advance in the permission information storage unit 855 of the telephone device adapter connected to the telephone of the organizer who hosted the telephone conference. Upon receiving the call request from the IP network 14, the IP network communication processing means 5000 of the communication device adapter connected to the organizer's telephone notifies the telephone identification number management means 900 of the call request. The telephone identification number management means 900 notifies the destination telephone of a message for inputting the telephone identification number. The message is a message that can be heard by the caller of the other party's telephone. Next, the IP network communication processing means 5
000 receives the telephone identification number from the destination telephone,
The received telephone identification number is stored in the telephone identification number management means 90.
Notify 0. The telephone identification number management unit 900 refers to the permission information storage unit 855 and checks whether the notified telephone identification number is set. If it is set, the IP network communication processing means 5000 outputs a message permitting participation in the telephone conference. This message can be heard by the caller of the other party's telephone. If the telephone identification number notified to the permission information storage unit 855 is not set, the IP network communication processing unit 5000 outputs a message not permitting participation in the telephone conference. This message is also a message that the caller of the destination telephone can hear by voice. Also, in the case where the organizer of the telephone conference hosts a plurality of telephone conferences, the telephone to be joined is often different for each telephone conference. Set a telephone identification number for each number. For example, when three telephone conferences are hosted as shown in FIG. 15, the telephone conference identification numbers are set to "1000" and "133" for each telephone conference hosted.
0 ',' 1600 ', and the telephone identification number for the telephone conference identification number' 1000 'for each telephone conference identification number,' 500, 501, 503 'for the telephone conference identification number' 1330 '. Phone identification number '50
0,600,700 'and the conference call identification number' 1 '
For 600 ', telephone identification numbers' 101, 102,
The settings are made as 105, 501, 502 '. In the description, the telephone identification number is input when the caller inputs the telephone number from the telephone. The telephone identification management means 900 of the telephone device adapter connected to the telephone may notify the telephone device adapter of the host of the telephone conference.

Next, a method of confirming participation in a telephone conference by inputting a password will be described. The password is also stored in the permission information storage unit 855 provided in the telephone adapter of the organizer of the telephone conference, but since the password is meaningless if known to anyone other than the caller. It is necessary for the caller to set his / her own password for the telephone conference identification number in advance. The setting method will be described in another embodiment. Here, the description will be given on the assumption that the password is already stored in the permission information storage unit 855 of the telephone device adapter of the telephone conference host. The password is also stored for each telephone conference identification number like the telephone identification number in FIG. The IP network communication processing means 5000 of the telephone device adapter of the host of the telephone conference sends the call request to the IP network 1
When the call is received from No. 4, the telephone conference participant password management means 1000 is notified that there is a call request. Teleconference participant password management means 1000 outputs a message prompting the input of a password to the other party's telephone from IP network communication processing means 5000. This message is a message that the caller of the destination telephone can hear by voice. The password is input by the caller of the other party's telephone, and the IP network communication processing means 5
000 receives the password, and notifies the password management unit 1000 of the received password.
The telephone conference participant password management unit 1000 refers to the permission information storage unit 855 and checks whether the password is set. Since a password is set in the permission information storage unit 855 based on the telephone conference identification number, it is supposed that the user is prompted to input the telephone conference identification number at the same time as prompting the input of the password. Then, it is assumed that IP network communication processing means 5000 receives the password input from the other party's telephone and the telephone conference identification number. If the notified password and the telephone conference identification number are set in the permission information storage unit 855, the telephone conference participant password management unit 1000 notifies the telephone of the other party of a message permitting participation in the telephone conference. If it is not set, a message not admitting participation in the conference call is sent to the other party's telephone. This notification is also a message that the caller of the other party's telephone can hear by voice.

The telephone conference identification number, telephone identification number, and password can be used to confirm participation in the telephone conference by arbitrarily combining respective permission information.

As described above, two or more pieces of voice data other than one's own voice received from another telephone to which the telephone adapter of the present invention is connected via the IP network are mixed to output voice. Therefore, it is possible to hold a telephone conference via an IP network by three or more callers.

Further, since an identification number is set for a telephone conference and the identification number is directly designated and transmitted, a telephone conference via an IP network can be held between specific participants.

Also, an identification number is set on the telephone connected to the telephone adapter, and the identification number of the telephone is transmitted from the telephone participating in the telephone conference to the telephone of the organizer hosting the conference. A telephone conference can be held between specific telephones via an IP network.

Also, the password assigned to each participant is managed for each telephone conference, and each participant is required to input a password at the time of participation, so that the registered password is compared and collated. Participants can be authenticated.

This embodiment is a voice data mixing means for making a call from another telephone connected to a telephone adapter via an IP network, mixing two or more voice data other than the own voice, and outputting a voice. The Internet telephone network system has been described in which 700 is provided so that a telephone conference can be held by three or more people using a telephone.

The telephone conference identification number management means 800 for managing the identification numbers of the set telephone conferences and the telephone identification number management means 900 for managing the telephone identification numbers of the participants of the telephone conference are provided. An Internet telephone network system has been described that is capable of authenticating conference participants.

[0139] The provision of the telephone conference participant password management means 1000 for storing and managing the password registered by the telephone conference participant enables authentication of the telephone conference participant. A telephone network system has been described.

Embodiment 4 In the fourth embodiment, the control information stored in the setting information storage unit from the IP network or the public line is stored in the setting information storage unit storing information for controlling the telephone device adapter provided in the telephone device adapter. An example in which information for changing the setting is input and the information in the setting information storage unit is changed will be described. FIG. 16 is a configuration diagram of each means showing the communication device adapter according to the fourth embodiment. In FIG. 16, an IP 1200 changes the control information by inputting change information for changing information for controlling the telephone device adapter from the IP network 14 and accessing a storage unit storing the control information. An IP network data read / write unit 1300 serving as a network data read / write unit inputs change information for changing control information for controlling the communication device adapter 12 from the telephone set 10, and stores the control unit in which the control information is stored. Telephone input data writing means which is a telephone input data writing unit for accessing and changing control information. 1
A setting information storage unit 400 stores control information for controlling the telephone device adapter 12.

Next, the operation will be described. For example, it is assumed that a maintenance work of the communication device adapter has occurred. For maintenance work, change information for changing control information is input from the telephone 10 using a push button or the like, and the change information is received by the public line signal transmitting / receiving means 1100 as a tone signal. The public line signal transmitting / receiving means 1100 passes the received change information to the telephone input data writing means 1300. Telephone input data writing means 13
00 accesses the setting information storage unit 1400 according to the change information passed from the public line signal transmitting / receiving unit 1100,
Change the setting information.

Further, change information may be input from a telephone other than the telephone 10 via the public line 13.
By doing so, for example, the control information stored in the setting information storage unit 1400 of the communication device adapter 12 can be changed from a remote location.

It is also assumed that a personal computer is connected to the IP network 14, for example. A personal computer connected to the network 14 specifies the IP address of the telephone device adapter, and inputs change information for changing the control information to the telephone device adapter 12 via the IP network 14. The change information is transmitted to the IP network communication processing unit 50
00 and received by the IP network communication processing means 5
000 passes the received change information to the IP network data read / write means 1200. IP network data read / write means 1200 changes the control information stored in setting information storage section 1400 according to the change information for changing the control information passed from IP network communication processing means 5000.

As described above, the control information generated for the maintenance work can be input from the existing telephone or general-purpose personal computer connected to the telephone adapter, and the setting information storage unit is stored in accordance with the input change information. Since the stored control information is changed, the cost of adding a data input / output device dedicated to maintenance work to the communication device adapter can be reduced. A user or the like can easily perform a maintenance setting operation using a conventional device.

Further, FIG. 12 described in the third embodiment will be described.
The input of the permission information such as the telephone conference identification number, the telephone identification number, and the password stored in the permission information storage unit 855 shown in (1) is performed by the telephone connected to the telephone device adapter or the personal computer connected to the IP network. Alternatively, the permission information storage unit 855 may be accessed and registered by the telephone input data writing unit 1300 when the telephone number is input from a remote telephone. When inputting from a personal computer via the IP network 14, the permission information storage unit 855 may be accessed and registered by the IP network data read / write unit 1200. It is thought that the frequency of new registrations, changes or deletions of registered information, etc., is high because permission information on telephone conferences can be entered and registered from a telephone connected to the telephone device adapter or a personal computer connected to the IP network. Registration work of the permission information related to the telephone conference to be performed can be easily performed.

In the fourth embodiment, IP network data read / write means 1200 capable of updating and writing data stored in a telephone adapter based on data received from the IP network by the telephone adapter. An internet telephone network system has been described, characterized in that maintenance work of control information for controlling the telephone device adapter can be performed from a computer such as a personal computer connected via an IP network.

Further, information for changing and registering information stored in the telephone adapter is input to the telephone adapter using a dial or a push button from a telephone, and the telephone apparatus is input using the input information. A telephone input data write unit 1300 capable of registering and changing information stored in the adapter is provided, and maintenance work of control information for controlling the telephone device adapter is performed.
An Internet telephone network system has been described which can be performed from a telephone connected to a telephone device adapter.

Embodiment 5 FIG. In the drawings of the first to fourth embodiments, the configuration diagram of each means showing the components of the telephone device adapter of the Internet telephone network system of the present invention is shown. In the fifth embodiment, the IP network communication is performed. A detailed internal configuration of the processing unit 5000 will be described. FIG. 17 is a network configuration diagram including a firewall on an IP network according to the fifth embodiment. In FIG. 17, 17, 2
7 is a firewall. For other symbols, see FIG.
The description is omitted because it is the same as. FIG. 18 is a configuration diagram of the IP network communication processing means 5000 according to the fifth embodiment. The IP network communication processing means 5000 in FIG. 15 can be applied to the IP network communication processing means 5000 shown in the first to fourth embodiments as it is.

In FIG. 18, reference numeral 5100 denotes a User Datagram Protocol as a communication protocol for transmitting / receiving audio data on the IP network 14.
(Hereinafter, referred to as UDP)
A UDP communication processing unit 5200 as a DP communication processing unit is a UDP port usage management unit as a UDP port usage management unit that transmits and receives voice data to and from a firewall via a specific UDP port. A UDP port communication confirmation unit 5400, which is a UDP port communication confirmation unit for examining the existence of a UDP port capable of transmitting and receiving data, has a Real Protocol as a communication protocol for voice data transmission / reception processing on an IP network.
RTP capable of performing processing of time transport protocol (hereinafter referred to as RTP)
RTP communication processing means, which is a communication processing unit.

Next, the operation will be described with reference to the flowcharts of FIGS. FIG. 19 and FIG.
Is the same process as in FIGS. 10 and 11 described in the second embodiment. FIG. 21 shows processing for the fifth embodiment. In the transmission / reception processing of voice data during a call state in the first to fourth embodiments, IP network communication processing means 5000 operates. A case where voice data is transmitted from the telephone device adapter 22 of the other party to the telephone device adapter 12 via the IP network 14 will be described. A header for transmitting and receiving audio data will be described with reference to FIG. The structure of a packet of voice data performed between the telephone device adapter 12 and the telephone device adapter 22 via the IP networks 14 and 24 is as shown in FIG. In the fifth embodiment, an IP header 51 and a UDP header 5
2 and the RTP header 53 are added to form an IP packet. When the voice data is transmitted from the voice device adapter 22 via the IP network 14, the voice device adapter 12 transmits the voice data I
UDP header 5 excluding IP header 51 from P packet
Take out the packet with 2. Next, the RTP communication processing unit 5400 extracts the packet with the RTP header 53 from the packet with the UDP header 52, and further,
The main part of the digital audio data from which the RTP header has been removed is sent to the audio data digital-to-analog converter 500, and is converted into analog audio data by the audio data digital-to-analog converter 500.
00 to the telephone 10. Although it has been described that the analog voice data converted by the voice data digital-to-analog converting means 500 is sent to the telephone set 10 via the public line signal transmitting / receiving means 1100, the direct voice data digital-to-analog converting means 500 performs the IP network communication processing means 5000. Public line signal transmitting / receiving means 1 via
The route may be such that analog audio data is transmitted to the telephone 100 and output to the telephone 10.

Next, the telephone 10 sends the IP network 14
A case where call information is transmitted to the telephone set 20 via the telephone will be described. The analog voice data body input from the telephone 10 is transmitted to the public line signal transmitting / receiving unit 1100, the connection destination determining unit 200, and the line connection switching unit 100 via
It is input to the P network communication processing means 5000. I
P network communication processing means 5000 converts the input analog audio data into digital audio data by audio data analog-to-digital conversion means 600. The converted digital audio data is input to the RTP communication processing unit 5400 of the IP network communication processing unit 5000 and is created as a packet to which the RTP header 53 has been added. Further, the UDP communication processing means 5100 causes the UD
The packet is created as a packet to which a P header 52 is added, and subsequently, as an IP packet to which an IP header 51 is added,
The message is transmitted to the telephone set 20 connected to the communication device adapter 22 of the communication partner via the P network 14.

By using the UDP, when the voice data packet does not arrive at the telephone adapter 22 connected to the telephone 20 of the other party, no retransmission processing is performed. For this reason, it is possible to improve the real-time characteristics of the voice data communication. In addition, by using RTP, the transmission time and counting of audio data packets can be managed, so that the real-time characteristics of audio data communication can be improved.

Next, in order to cope with a case where the IP network route is blocked by the firewalls 17 and 27, a configuration for confirming whether a UDP port can be used will be described. It is assumed that information indicating that the network environment of the communication partner is blocked by the firewall is stored in the address conversion table 302 together with the IP address. By being stored in the address conversion table 302, it is possible to know the state of the network environment of the other party when making a call.

The procedure for making a call from the telephone connected to the telephone device adapter and the procedure for processing when a call is made are the same as those in FIGS. 10 and 11 described in the second embodiment. If it is determined that a call can be made to the telephone, a process for confirming the existence of a port capable of communicating with the communication device adapter of the communication partner is performed. FIG.
Telephone 10 on telephone 9,20,21
2 shows a flowchart of a procedure for making a call via a. FIG.
9 is the same process as FIG. 10 described in the second embodiment,
FIG. 20 is the same process as FIG. 11 described in the second embodiment. FIG. 21 is a flowchart of the process added in the fifth embodiment. S2400 to S2406 in FIG.
0 is a process corresponding to the process of S24. In FIG. 19, when the corresponding IP address can be obtained based on the telephone number input from the telephone 10 (S23), the UDP
The port communication confirming unit 5300 scans each port of the other party's communication device adapter via the IP network 14 and checks whether or not an arbitrary UDP port can be accessed (S2400). The UDP port communication confirmation means 5300 transmits data for confirming whether communication is possible by designating a predetermined port number. If the answer data arrives within a certain period of time from the telephone adapter connected to the telephone of the other party, the port number can be used. If the UDP port can be accessed by an arbitrary UDP port, the port number of the UDP port checked by the UDP port communication confirmation means 5300 is set to the destination port number of the UDP header 52, and the voice data communication processing is performed by the arbitrary UDP port Is started (S2401). If not possible,
It is checked whether communication is possible with the previously specified UDP port managed and stored by the UDP port use management unit 5200 (S2402). Generally, a firewall does not recognize the specification of an arbitrary UDP port, but it is also possible to set a firewall so that a limited specific UDP port can be used. In this case, the limited specific UDP port is managed and stored in advance in the UDP port use management unit 5200. If this is possible, communication processing of audio data is started at the specified UDP port (S2403). If not possible, a search for another communication port can be made to explore further possibilities. In the example of this flowchart, it is checked whether or not the normally used HTTP port can be accessed (S2404). However, in order to confirm whether access is possible with the HTTP port as in S2404, the HTTP port communication confirmation means described in the sixth embodiment is required. Here, if it is determined as “No” in the processing of S2402, it is confirmed whether or not the access through the HTTP port is possible. If “No” in the processing of S2402, the error notification processing of S2406 is performed. You may branch to.

As described above, since UDP and RTP, which are excellent in the real-time characteristics of the communication processing, are used, the voice quality of a call can be improved. Also,
Generally, a firewall that does not allow the use of an arbitrary UDP port is set so that a very specific UDP port can be used, and the specific UDP port number is set in the communication device adapter. By storing, it is possible to perform communication processing of audio data beyond the firewall. Further, in general, any UD
Since it is possible to scan available UDP ports for firewalls that do not allow the use of P ports, even if the available UDP ports are unknown, they are searched for and used for voice data communication. Processing can be performed.

In the fifth embodiment, when the telephone adapter makes a call via the IP network,

Shown in This IP network communication processing means 5000 can be directly applied to the same means in the drawings of the first to sixth embodiments. The configuration diagram of the network system according to the seventh embodiment is the same as the network configuration diagram shown in FIG. 17 of the fifth embodiment.

In FIGS. 24 and 25, reference numeral 5500 denotes an audio data packet encoding unit which compresses audio data itself and changes the header of a packet of a standard format such as RTP or HTTP to a compressed header which is limited to minimum necessary information. Audio data packet encoding means, 5600
Is an audio data packet decoding unit which is an audio data packet decoding unit for decompressing the received audio data itself and analyzing the compressed header to obtain a header of a packet of a standard format such as RTP or HTTP. The buffer size is adjusted such that the digital voice data packet received at a discontinuous timing from the destination telephone set 20 connected to the IP network at a discontinuous timing due to a change in network traffic is converted into an analog signal and transmitted at a constant delay. A reception buffering unit 6200, which is a reception buffering unit for temporarily storing in a reception buffer that can be changed, 6200
Creates a digital voice data packet to be transmitted when transmitting a digital voice data packet to the destination telephone set 20 connected to the IP networks 14 and 24;
Transmission buffering means 6300, which is a transmission buffering unit for performing processing for adding only necessary data to packet assembly before storing and sending the data to a transmission buffer whose buffer size can be changed, is connected to the IP networks 14 and 24. When transmitting digital voice data packets to the telephone set 20, a redundant packet issuing unit for transmitting the same voice data packets in a variable number of duplicates in order to cope with a packet loss of voice data generated according to the situation of network traffic. The redundant packet issuing means 6400 is used to reduce network traffic when transmitting digital voice data packets to telephones connected to the IP networks 14 and 24.
The packet generation filtering unit 6500 is a packet generation filtering unit that can reduce the number of voice data packets to be transmitted.
A network traffic monitoring unit 6600, which is a network traffic monitoring unit for monitoring the reception timing of the voice data packet from the network unit 4, stores the statistical data of the network traffic status and averages the data in each time zone in a cycle such as one day or one week. Network traffic statistical data management means, which is a network traffic statistical data management unit that calculates a parameter indicating a typical traffic situation.

Next, the operation will be described. In the transmission / reception processing of voice data during a call state as in the first to sixth embodiments, the IP network communication processing unit 5000 is used.
Works. This IP network communication processing means 500
The basic operation of 0 is performed in the same manner as in the fifth to sixth embodiments. Here, the RTP communication processing unit 5400 and the HTTP
When sending or extracting audio data to / from the communication processing unit 5800, the audio data packet encoding unit 5500 uses the audio data and RTP or HT
The TP header is compressed, and the packet decoding means 56
00 decompresses audio data and RTP or HTTP headers. The compression of the RTP or HTTP header also includes a case where a modified header in which only necessary minimum information is collected compactly without actually conforming to a standardized header format.

Further, since various data traffics exist on the IP network, voice data packets do not always arrive continuously at fixed time intervals. Such variation in the arrival time of each packet is called fluctuation of the transmission time. When a packet is received in order to absorb the fluctuation of the transmission time, the voice data packet is stored in a reception buffer and output to the public line signal transmitting / receiving means 1100 on the analog side at regular intervals. In this case, even if a delay occurs in each packet, the timing at which the audio data is output to the output side becomes constant as long as it is within the capacity of the reception buffer, and the reproduced sound is not interrupted. This processing is performed by the reception buffering means 6100. Reception buffering means 610
Reference numeral 0 denotes a unit having the reception buffer 6101 and performing the above-described processing. Since the delay in which the sound is reproduced is increased by the length of time accumulated in the reception buffer 6101, the capacity size of the reception buffer cannot always be increased. Therefore, this capacity size is traded off from actual call quality for delay and fluctuation. ... sounds as if a blank time "..." was inserted, like "Oh ... In order to fill in the blank time "...", a reception buffer is prepared.
By delaying the entire reproduction time, the process of the reception buffer is to remove the interruption of the sound. As the size of the receiving buffer is increased, the interruption is eliminated and the voice quality is improved, but the overall delay is increased, so that the talk timing is likely to be delayed and it is difficult to hear. That is,
Increasing the receive buffer size absorbs fluctuations and improves voice quality, but on the other hand, increases delay and makes it difficult to hear.
The timing of speaking becomes easier. The receiving buffer size is determined by a trade-off between the two features. ) Should be set to the optimal value. However, in reality, the optimum value fluctuates according to the state of network traffic and the like. Receive buffering means 6100
Thus, the capacity size of the reception buffer 6101 can be changed according to an arbitrary condition. Also, in order to cope with a case where the buffer overflows frequently, the capacity size of the buffer is set to be large, and the data sent out from the audio data digital-to-analog conversion means 500 on the reproducing side is always only a part of the data. There is also. In this case, it is conceivable to control not only the capacity size of the reception buffer but also the size of the data to be sent to the audio data digital-to-analog converter 500 on the reproducing side so as to be changed according to various conditions.

Similarly, in order to cope with various data traffic conditions on the IP network, it is conceivable that the transmitting side also changes the size of the voice data packet to be transmitted to the IP network 14. To this end, the transmission buffering means 6200 has a transmission buffer 6201. Transmission buffering means 620
0 indicates that audio data is stored in the transmission buffer 6201 in a fixed amount before transmission. The smaller the packet size of the voice data to be transmitted, the smaller the delay and the better the call quality. There is a limit. If the size is further reduced, the amount of packets increases, so that the amount of network traffic increases. Therefore, control is performed to change the size of the transmission buffer according to the network traffic situation.

Similarly, in order to cope with the traffic situation of various data on the IP network, in the case where packet loss of transfer data frequently occurs in the UDP communication processing, packets of audio data having exactly the same contents are prepared. A countermeasure for transmitting a redundant message as a backup is considered.
This processing is performed by the redundant packet issuing unit 6300. This redundant packet is not always issued, but if network traffic increases, the delay of the entire packet increases. To reduce unnecessary packets,
It is necessary to adjust so that redundant packets are not issued.
Network traffic is not increasing much,
When packet loss occurs frequently, if control is performed to issue a redundant packet, packet loss is reduced and communication quality is improved.

Similarly, in order to cope with various data traffic conditions on the IP network, when the network traffic increases, the amount of data to be transmitted is reduced so that the communication quality is not affected. Control that does not transmit the packet of the audio data is considered. This processing is performed by the packet generation filtering unit 6.
400. Here, as a condition for performing the filtering, a setting except for a case where the volume level of the audio data is equal to or less than a certain value can be considered. This is because in human hearing, it has already been confirmed that even if a sound at a certain volume level is not reproduced, there is no effect on the call. As a result, by controlling the amount of voice data to remove the limit level of the volume of voice data to be removed at the time of transmission as network traffic increases, it is possible to continue a voice call with almost no loss of voice quality. it can.

Similarly, it has been described that various means of performing various communication controls by each means in the communication processing to cope with the data traffic situation on the IP network.
Therefore, in order to grasp the network traffic situation, the network traffic monitoring means 6500 continuously records the reception timing of the voice data packet. Thereby, the amount of network traffic is estimated, and the conditions for the communication control are appropriately changed. For example, in the case of the reception buffering unit 6100, when the network traffic monitoring unit 6500 confirms that the network traffic has been increased, it notifies the reception buffering unit 6100 to increase the capacity size of the reception buffer 6101. When the capacity size of the reception buffer is increased, the reception buffer 6
Since packets are stored in the voice data 101 and passed to the voice data digital-to-analog conversion means 500, network traffic can be eliminated. Conversely, when the network traffic decreases, the packet arrives at the communication device adapter at a stable timing.
A notification is made to the reception buffering means 6100 so that the capacity size of the reception buffer 6101 is reduced.

Further, in order to cope with the traffic situation of various data on the IP network, statistical data is used for changing the various parameters for the communication control. Network traffic monitoring means 6500
The network traffic statistical data management unit 6600 receives the data monitored and stored by the network traffic statistical data management unit 6600, and performs communication control by the above-described reception buffering unit 6100, transmission buffering unit 6200, redundant packet issuing unit 6300, and packet generation filtering unit 6400. Provide necessary information. In a cycle such as one day or one week, the average network traffic tendency is determined by the network traffic statistical data management means 6600.
Can be referred to for performing communication control by each means.

In the configuration shown in FIG. 24, the communication processing means includes an RTP communication processing means 5400 and a UDP communication processing means 5100. In the configuration shown in FIG. 25, the communication processing means is an HTTP communication processing means. 5800 and a TCP communication processing unit 5700. The reception buffering unit 6100, the transmission buffering unit 6200, the packet generation filtering unit 6400, the network traffic monitoring unit 6500, and the network traffic statistical data management unit 6600 are provided in common in the configuration diagrams of FIGS. However, the redundant packet issuing means 6300 is provided only in the configuration diagram shown in FIG. This is because the UDP communication processing means 5100 and the redundant packet issuing means 6300 are related. U
Since the DP has a feature that data is sent to the destination without establishing a session, the UDP itself does not have a function to cope with the packet loss even if the packet loss frequently occurs. Therefore, a redundant packet issuing unit 6300 is provided to support UDP. On the other hand, TC
Since P starts communication after establishing a session, it has the characteristic that it retries as many times as possible until data can be reliably communicated. Therefore, since the TCP does not need to support the retry function, there is a reason that the communication device adapter of FIG. 25 does not have the redundant packet issuing unit 6300.

As described above, unique compression is performed on the header portion of the packet of the audio data to be communicated. Therefore, the packet size can be made smaller than the standard packet size, and network traffic can be reduced. This unique compression means, for example, that the information in the header section is compressed using a compression program to reduce the size, or that the header section has only the data necessary for the communication device adapter which is an element of the present invention. Point to do.

Further, even if the transmission time of each packet of the audio data to be communicated fluctuates, the data is accumulated until it reaches a certain size at the time of reception and is sent to the analog playback side. Even if stable, stable call quality can be maintained.

In transmitting each packet of voice data to be communicated, the packet size is reduced when the amount of network traffic is small, and the packet size is increased when the amount of network traffic is increased. Even if the situation is unstable, stable call quality can be maintained without affecting network traffic.

Further, since a redundant packet can be issued when a packet loss frequently occurs during transmission of each packet of voice data to be communicated, even in a situation where network traffic frequently causes a packet loss, Stable communication quality can be maintained.

Also, when transmitting each packet of voice data to be communicated, if the amount of network traffic increases, the transfer of voice data packets that do not affect call quality under conditions such as a certain volume level or less is not performed. As a result, stable communication quality can be maintained even when the amount of network traffic increases.

Further, the reception timing of each packet of the voice data to be communicated is measured, the network traffic situation is estimated, and various parameters of the communication processing are adjusted. The optimal communication process can be performed according to
Stable communication quality can be maintained.

Since the result of measuring the reception timing of each packet of the audio data to be communicated is accumulated and can be referred to as data indicating the network traffic status in a cycle such as one day or one week, the average is obtained. It is possible to perform optimal communication processing control corresponding to various network traffic conditions, and maintain stable communication quality.

In the seventh embodiment, with respect to the telephone connected to the telephone device adapter, the other telephone connected to the telephone device adapter of the same type recognizes that the connection destination is the telephone device adapter of the same type. At this point, the audio data packet encoding means 5500 for compressing the audio data itself, changing the header of a packet in a standard format such as RTP or HTTP to a compressed header limited to the minimum necessary information and transmitting the audio data, And an audio data packet decoding means 5600 for decompressing the received compressed audio data itself and analyzing the compressed header to obtain a header of a packet in a standard format such as RTP or HTTP to reduce the amount of transmitted / received data. Characterized in that efficient call data transmission / reception processing can be performed. It described the Netto telephone network system.

Further, a digital voice data packet received at a discontinuous timing from a partner telephone via an IP network due to a change in network traffic is converted into an analog signal for a telephone connected to the telephone adapter. Buffering means 6100 for temporarily storing in a receiving buffer whose buffer size can be changed so that the timing for sending out the data becomes a constant delay, and the analog voice signal can be transmitted to the telephone at a stable timing. Internet telephone network system to be described.

When transmitting a digital voice data packet to a telephone connected to the telephone device adapter to the telephone of the other party via the IP network, a digital voice data packet to be transmitted is created and a buffer size is set. Transmission buffering means 6200 for performing a process of adding only necessary data to the packet assembly before storing and sending the data to a transmission buffer capable of changing the transmission buffer, and realizes an optimal digital voice data packet transmission mode according to network traffic conditions. An Internet telephone network system has been described which is capable of transmitting high quality voice data.

Further, when transmitting a digital voice data packet to a telephone connected to a telephone device adapter via an IP network to a partner telephone, a packet loss of voice data generated according to a network traffic situation. In order to cope with the above problem, a redundant packet issuing unit 6300 for transmitting the same voice data packet in a variable number by overlapping is provided, so that high quality voice data can be transmitted even if a network traffic condition is deteriorated and packet loss occurs. An Internet telephone network system characterized by the above has been described.

Further, when a digital voice data packet is transmitted to a telephone connected to a telephone device adapter via an IP network to a telephone of the other party, a transmission target is to be reduced in order to reduce network traffic as much as possible. A packet generation filtering unit 6400 that can reduce the number of voice data packets;
An internet telephone network system characterized in that high-quality voice data transmission can be performed while suppressing an increase in network traffic due to voice data has been described.

Further, the network traffic monitoring means 6500 for monitoring the reception timing of the voice data packet received via the IP network for the telephone connected to the telephone device adapter analyzes the network traffic condition and finds any specific condition. After detecting that the situation is the situation, an instruction is given to change the operation status of the various means of the reception buffering means 6100, transmission buffering means 6200, redundant packet issuing means 6300, and packet generation filtering means 6400 provided in the communication device adapter. An Internet telephone network system has been described, which is characterized by realizing optimal transmission / reception processing according to network traffic conditions and capable of transmitting high-quality voice data.

[0192] Also, for the telephone connected to the telephone device adapter, the network traffic monitoring means 6500 which receives the voice data packet received via the IP network receives network data status statistical data from the network traffic monitoring means 6500 and accumulates the data. One day or one

An Internet telephone network system characterized by the above has been described.

The above HTTP access is HT
By assuming that the TP relay server is a Web server and assuming that the communication device adapter has a Web browser, each of the communication device adapters sends voice data to the HTTP relay server as a Web server by a message of POST in HTTP. Can be.
In addition, each call device adapter can acquire a location where voice data output from a telephone connected to each call device adapter is accumulated by a GET message. This is referred to as HTTP access. The voice data can be temporarily stored in the HTTP relay server, and the voice processing can be realized by the voice device adapter connected to another telephone that needs the voice data to obtain the voice data. Reference numeral 8200 denotes telephone call information for confirming whether or not each telephone device is calling the telephone device adapter in response to a telephone call from the telephone device adapter, and for responding when there is an inquiry about each telephone device adapter. Telephone call information management means 8300 as a management unit includes two telephone adapters, for example, telephone 10 and telephone 2
0, the communication between the communication device adapter 12 connected to the telephone 10 and the communication device adapter 22 connected to the telephone 20 is performed by connecting the HTTP relay server 18 to the Web server, and the communication device adapter to the Web browser. HTTP connection changing means 8400, which is an HTTP connection changing unit for changing the connection so as to change the connection so that
This is a TCP / IP packet header conversion unit, which is a TCP / IP packet header conversion unit that converts the IP address of the P header portion and the port number of the TCP header into the IP address and port number of the communication device adapter of the final destination.

FIG. 28 is an internal configuration diagram of the IP network communication processing means 5000 according to the eighth embodiment. I in FIG.
The P network communication processing means 5000 can be directly applied to the same means in the first to seventh embodiments.

In FIG. 28, reference numeral 7300 denotes an HTTP telephone calling means which is an HTTP telephone calling unit for transmitting telephone call information by HTTP access to the HTTP relay server 18, and 7100 denotes a telephone call information managing means 8200.
HTTP polling means, which is an HTTP polling unit for checking the call status of the callee adapter of the callee at the callee, which is stored in the communication device, by polling HTTP access using the inquiry information. This is a telephone call communication unit which is a telephone call communication unit that reports that a call is made to the communication device adapter of the call destination when it is determined that the adapter is blocked by the firewall.

FIGS. 29 and 30 show a first example and a second example of the configuration of each means showing the HTTP relay server management server of the Internet telephone network system according to the eighth embodiment. 29 and 30, reference numeral 9200 denotes a plurality of HTTs.
HTTP relay server load status monitoring means 9100, which is an HTTP relay server load status monitoring unit for monitoring the load status of the P relay server, designates an HTTP relay server 9100 that specifies an HTTP relay server to be used in the call processing in response to an inquiry from the call device adapter. It is an HTTP relay server designating unit that is a server designating unit.

The first example of FIG. 29 shows an HTTP relay server management server which prepares a plurality of HTTP relay servers 18 themselves of FIG. 27 and manages them collectively. In the second example of FIG. 30, only processing means necessary for connection negotiation with the communication device adapter is extracted from the HTTP relay server 18 of FIG. 27, and the extracted processing means is incorporated in the HTTP relay server management server 180, and The figure shows a mode in which the relay server management server 180 performs processing up to connection negotiation. In this case, since the transmission / reception processing of the voice data of the call after the connection negotiation is performed only by the TCP / IP packet header conversion means 8400, the HTTP relay server can be realized by incorporating only such means.

Next, the operation will be described. First, FIG. 31 shows a form of a network configuration including a communication device adapter and an HTTP relay server. FIG. 31A shows HT
A method is shown in which the TP relay server 18 is executed assuming it is a provider. The means for checking that a telephone is connected to the telephone to which the intercom adapter is connected is H
There is a method in which information stored in the telephone call information management means 8200 which is a management area of the TTP relay server 18 is periodically polled and checked, or a mail, an instant message, and a public line call are checked from outside. . FIG. 31B shows the firewalls 17 and 27.
In an environment where the communication device adapters 12 and 22 are provided in a network environment protected by an external device and an external WWW server or proxy is provided in a network environment blocked by the same firewall, the external WW is used.
A method of executing an HTTP relay server program on a W server or the like can be considered. In FIG. 31C, a dedicated terminal (H) is set in a network environment blocked by a firewall.
A method is considered in which a telephone terminal capable of making a call with a terminal that executes a TTP relay server program) is installed, and a call is made between the installed telephone terminal and a dedicated terminal. Here, three forms of (A), (B) and (C) are shown, but the form of (A) (HTTP by a provider or the like)
The method for executing the relay server will be described based on the flowcharts (polling method) in FIGS.

The procedure for making a call from one telephone adapter to the other telephone adapter is as follows. First, the receiver of the telephone call is picked up, a telephone number is entered, and a telephone call is made based on the entered telephone number. Number IP address conversion means 3
00 is converted to the IP address of the other party. I
An example of converting to a P address is the same as that described in the first embodiment.

(In the case of the polling method) S22 in FIG.
To convert the telephone number to an IP address,
If it can be converted to a P address, the HTTP telephone calling means 7300 sets a flag for the IP address of the telephone call information management means 8200 in the HTTP relay server 18 for the IP address for which a call is to be made. Information is set (S62). The management area for each IP address of the telephone call information management means 8200 is always
Since the own management area in the telephone call information management means 8200 in the HTTP relay server is periodically referred to by the HTTP polling means 7100 of the telephone equipment adapter of the other party of the call, it is connected to the telephone of the other party. The intercom adapter can know that a call is being made.

(In the case of mail or instant message) If the IP address can be converted from the telephone number in the confirmation processing in S23 of FIG. Sends an e-mail or an instant message to inform that the other party's telephone is being called. The processing for mail and instant messages is not specifically illustrated in the flowcharts of FIGS.

(In the case of informing by calling from the public line) If the telephone number can be normally converted to the IP address in S23 of FIG.
0, the telephone line is called from the public line side, and the telephone adapter connected to the called telephone instantly notifies that the telephone call is being made.

Then, the other party's communication device adapter also sends a call tone to the telephone connected to the communication device adapter to start a call. If the receiver of the other party's telephone is picked up, it will be in a call state, and each telephone equipment adapter will go to get the other party's call data,
The call data transmitted by the user is transmitted to the HTTP relay server as needed. This continues until disconnected. The voice data buffer is where voice data is sent from this telephone device adapter and temporarily stored until it is taken out from the other telephone device adapter, and the voice data buffering means 8100 performs transmission / reception processing of voice data of this voice call. Do. S66 and S66 in FIG.
The processing of steps 67 and S68 is a procedure from the time when a call is received by another party to a state where the telephone is in a call state and the call is continued, and S62, S63, S64 and S65 in FIG. This is a process of a procedure in which the receiver of the other party's telephone is picked up and the communication state is established, and the procedure is continued until the call is disconnected. Since the two telephones make a call via the HTTP relay server in the same manner as when making a call and when making a call, the two telephones mutually communicate with the HTTP relay server after the above-described call state is established. The process of transmitting and receiving call data via S66-S68 in FIG.
33 corresponds to the description of the processing from S62 to S65 in FIG.

Next, a flowchart (polling method) of the HTTP relay server shown in FIG. 34 will be described. The HTTP relay server 18 accepts only HTTP access from outside via the IP network. FIG.
Then, it is confirmed by the HTTP communication processing unit 5800 whether or not the data of the HTTP access has been received in S70. Only in the polling method, there is an HTTP access for confirming whether or not each telephone adapter is calling itself. Other than that, there are access to make a new call to another phone, access to send voice data and obtain voice data for yourself, and HTTP access to contact when disconnecting a call. I do. In S71, if it is determined that the HTTP access makes a new call to another telephone, the telephone call information management means 8200 accesses the management area of the other party of the call, and determines whether the telephone is already in use or not. Check (S75). If it is on the phone, the HTTP message on the phone is returned (S7).
6, S77), otherwise, the fact that the telephone call has been started is returned as an HTTP message (S78). When the communication state is established, the voice data delivered from the telephone device adapter is temporarily stored (S79), and the voice data buffering means 8100 manages the voice data so that it can be collected by another telephone device adapter. . If there is call data in the voice data buffer area of the call destination, the call data is used as an HTTP return message as voice data buffering means 8100 and HTTP communication processing means 5800.
Is transmitted to the telephone device adapter connected to the telephone at the destination (S80). Also, in the process of S71,
In the case of HTTP access for confirming whether or not the telephone device adapter is making a call, the telephone call information management unit 8200 manages whether the telephone connected to the telephone device adapter of the confirmation request source is calling. The information is checked (S72). As a result of the check, if there is a telephone call (S73), information indicating that the telephone call is made is transmitted by the HTTP communication processing means 5800 to the telephone device adapter connected to the telephone of the confirmation request source (S74). If it is determined in step S71 that the access is HTTP access for disconnecting the call, the telephone call information management unit 8200 changes the management information of both the caller and the callee to information indicating that the caller is on standby. (S81).

As described above, since the general firewall can access the external Internet by HTTP, the telephone adapter can perform telephone calling and telephone processing via the HTTP relay server. The user can make a call via the IP network without having to make any setting changes to the firewall.

The HTTP relay server sends and receives call data after the first connection negotiation process between each of the call device adapters. However, since this processing load becomes considerably heavy, the transmission and reception of the call data is performed by HTTP relay. If the communication is performed directly between the two communication device adapters without going through the server, the processing load on the HTTP relay server is reduced,
Even if many users make a call and call processing is concentrated, the processing can be continued without delay and call quality can be maintained. For this reason, the HTTP connection changing means 8300 changes the connection between the HTTP and the TCP directly after the first connection negotiation so that the connection between the two adapters is established.

As described above, transmission and reception of call data
Since the processing load on the HTTP relay server is reduced because the communication is performed directly between the two communication device adapters without passing through the HTTP relay server, many users make calls and call processing is concentrated. Process can be continued without delay, and communication quality can be maintained.

Further, in the HTTP relay server, the communication data is transmitted and received after the first connection negotiation process between the communication device adapters. However, since the processing load becomes considerably heavy, the process performed by the HTTP relay server is not performed. It is conceivable to perform only the simplest processing possible. this is,
At the point in time when the two relay device adapters for making a telephone call are connected by the HTTP relay server and the preparation for call processing is completed, the IP address of the IP header part in the packet of the voice data transferred from the two relay device adapters to the HTTP relay server And the port number of the TCP header are directly converted into the IP address and port number of the final destination communication device adapter.
400.

[0209] As described above, transmission and reception of call data is performed by H
As processing on the TTP relay server, the IP address of the IP header part in the packet of the voice data and the port number of the TCP header are directly converted to the IP address and port number of the communication device adapter of the final destination, and the Since the processing load is reduced, even if many users make telephone calls and call processing is concentrated, the processing can be continued without delay and communication quality can be maintained.

On the other hand, even if efficient communication processing is performed in the HTTP relay server, if the number of users increases and the number of telephone adapters requesting call processing increases, the processing performance of one HTTP relay server is limited. There will be someday going bankrupt. Therefore, by preparing a plurality of HTTP relay servers and distributing the call processing of each of the call device adapters, each user can maintain a comfortable call state.

Therefore, an HTTP relay server management server that integrally manages the plurality of HTTP relay servers is required. The relationship between the HTTP relay server management server and the HTTP relay server is shown in FIGS.

The address conversion table 302 is a table that stores telephone numbers and terminal identifier names in association with each other.

In recent years, even in a company, from the viewpoint of saving IP addresses, IP addresses are changed to DHCP (Dynamic Host).
t Configuration Protocol)
In many cases, it is dynamically assigned by a server or router. In some cases, an IP address is dynamically allocated in a dial-up manner. In such a case, in order to specify the other party's communication device adapter at the time of calling, recognition is performed not by the IP address but by the name which is the identifier of the communication device adapter. By transmitting and receiving an IP address to and from the other party of a call using a mail protocol by specifying a name at the time of calling, it becomes possible to specify the IP address for subsequent call processing.

Embodiment 10 FIG. In the tenth embodiment, a method different from that of the ninth embodiment will be described for a method of dynamically assigning an IP address of a telephone device adapter. FIG.
FIG. 26 is a configuration diagram of each means of the telephone device adapter according to the tenth embodiment. In FIG. 36, reference numeral 5001 denotes a public line communication processing unit which is a public line communication processing unit, and performs communication processing via an IP network by using PPP (poi) via a public line.

This is a means that can be performed on a dial-up connection using a protocol such as "tocol".

By the public line communication processing means 5001,
A call is made by replacing the processing via the IP network described in the first and second embodiments with communication processing on a dial-up connection.

In the tenth embodiment, a public line communication processing means 5001 can perform communication processing via an IP network to a telephone connected to a telephone device adapter over a dial-up connection using a protocol such as PPP via a general public line. The Internet telephone network system has been described in which a telephone call can be made by replacing processing via an IP network with communication processing on a dial-up connection.

Embodiment 11 FIG. In the eleventh embodiment, a telephone device adapter capable of making a telephone call by replacing processing via an IP network with communication processing on a serial port connection to a terminal adapter will be described. FIG. 37 is a configuration diagram of each means of the telephone device adapter according to the eleventh embodiment. In FIG. 37, reference numeral 5002 denotes a serial port communication processing means, which is connected to a general terminal adapter capable of performing communication processing via an IP network on a dial-up connection by a protocol such as PPP via a general public line via a serial port such as RS232C. This is a serial port communication processing means that can be performed after connection. In addition, the communication device adapter 12 connects the serial port cable 33. Other symbols are the same as those in FIG. 9 of the second embodiment.

[0229] For a telephone connected to the telephone equipment adapter of the eleventh embodiment, a general terminal adapter capable of performing communication processing via an IP network on a dial-up connection by a protocol such as PPP via a general public line is connected to an RS232C. Serial port communication processing means 5002 that can be performed after connecting with

Embodiment 12 FIG. Embodiments 1 to 11 above
In the above, the call information input to the call device adapter was output from the call device (telephone). However, the communication device is not limited to a telephone, but may be a personal computer, a mobile phone, or the like.

Embodiment 13 FIG. As described in the second embodiment, in both cases where a call is made and a case where a call is made, the communication device adapter learns the IP address of the other party of the call. However, when a call is made, it is sufficiently assumed that the same person will be called again. However, when a call is made, it is not always possible to call that person. For example, when making a call for the purpose of selling sales or inquiring for specific information, there is almost no case where the called person calls the called person. Therefore, when a telephone call is often made for such a purpose, the other party's I who does not expect to make a telephone call
For storing the P address, the address conversion table 30 is used.
It is fully assumed that two entries will be consumed.

As described above, in the communication device adapter of the user who often makes a telephone call for such a purpose,
When a call is made, it is possible not to learn the IP address of the other party of the call.

When a call is made as described above, the IP
It is conceivable to adopt a process specification that does not perform address learning, but such a situation is expected to change, so the user can change the setting whether to use such a process specification By doing so, the convenience is improved for the user. Therefore, the above-described maintenance function is used to set the communication device adapter so that it is possible to select whether or not to learn the IP address of the communication partner when a call is made. Alternatively, when the user makes a telephone call, address learning prohibition information for instructing not to learn the IP address is input after the telephone number of the other party using the dial or push button of the telephone. Or, enter it before the other party's phone number. Address learning prohibition information is set in advance on a predetermined dial or a predetermined push button. The public line signal transmission / reception unit 1100 detects the address learning prohibition information and notifies the IP address learning unit 400 that the learning of the IP address is not performed. In this way,
The learning of the IP address of the other party of the call may not be performed.

In the second embodiment, the public line signal processing unit can make a telephone call for the learning process of the IP address learning unit for learning the address information of the communication device from the calling party and the called party. Although an example of an Internet telephone network system characterized in that it is performed by both the calling party and the calling party has been described, in the thirteenth embodiment, the public line signal processing unit performs An example of the Internet telephone network system has been described in which the learning process of the IP address learning unit for learning the address information of the communication device is not performed on the called side.

Also, the public line signal processing unit performs the learning process of the IP address learning unit for learning the address information of the calling device from the called party and the called party, and performs the learning process with the called party. A mode for both parties to make the call,
Mode setting is possible by allowing the calling party to select between two modes, in which the learning process of the IP address learning unit, which learns the address information of the communication device from the calling party, is not performed by the called party. It is also possible to build a simple Internet telephone network system.

Embodiment 14 FIG. In the fourteenth embodiment, a mechanism for exchanging IP addresses after the end of the call described in the second embodiment will be described in further detail. FIG. 38 shows that for both users,
A schematic configuration in a case where a telephone call is performed using a telephone device (telephone) and the telephone device adapter is shown. Telephone circuit I / F (interface) control circuit 11 in the adapter of FIG.
Reference numeral 10 is a general term for the public line signal transmission / reception unit 1100, the line connection switching unit 100, the connection destination determination unit 200, and the like.

After the end of the call, the user places the handset of the communication device on the main body of the communication device after an appropriate time has elapsed.
This state of the handset is generally called on-hook. Conversely, a state in which the handset is picked up is called off-hook. If the on-hook state of the handset is transmitted to the public line exchange as it is, the line for the call is disconnected, and the exchange of IP address information becomes impossible. Therefore, the public line signal transmitting / receiving means 1100 of the telephone device adapter detects the on-hook state of the telephone device, and switches the circuit of the public line by the telephone line I / F control circuit 1110 so as to indicate the off-hook state of the telephone device. That is,
At this point, the communication device itself is disconnected from the public line,
The intercom adapter is directly connected to the public line instead of the intercom.

As described above, even if the user ends the call and puts down the receiver, the connection can be maintained and the IP address information can be transmitted and received.

This means that the public line signal processing unit
Immediately after both users on the call end the call and go on-hook on the handset, hold the connection on the public line without disconnecting it and send the call information to the other party sending the call information. An example of an Internet telephone network system is described in which address information corresponding to the identification information of the communication device on the transmitting side is transmitted via a public line.

FIG. 39 shows an example of a sequence of a procedure for transmitting and receiving IP address information. Here, the sequence when a call is made from the telephone A to the telephone B is shown by (1) to (9). The called telephone B emits a disconnect tone to signal the start of the first processing (1). At the time of transmitting the disconnect tone of the first signal, it is necessary that the user already has the receiver on-hook in both communication devices. Therefore, after the call is ended, the user waits for a sufficiently long time, for example, about 5 seconds, until the user hangs up the receiver, and then transmits the first disconnection tone. By doing so, in most cases, the IP address transmission / reception process succeeds. If the disconnection tone is transmitted while the telephone A is still in the off-hook state, the call fails, so that the IP address transmission / reception processing is executed again after the next call.

[0241] This means that the public line signal processing unit is not supposed to be able to predict that the other user will go on-hook immediately after one of the users on the call ends the call and goes on-hook on the handset. After a lapse of time, while maintaining the connection on the public line without disconnecting, address information corresponding to the identification information of the communication device on the side transmitting the call information to the other party transmitting the call information An example of an Internet telephone network system in which the Internet telephone network is transmitted via a public line is described.

Further, after the end of the call, in order for the on-hook operation of the handset to be ready for the start of the IP address transmission / reception processing, when the on-hook operation is performed on one of the communication devices, the communication device adapter connected to the other device is connected to the other device. By transmitting a busy tone (a tone indicating busy) to the user, the on-hook operation of the receiver can be encouraged. In general, it is more customary for the user to hang up the handset immediately after the busy tone than when there is no sound. In addition, it may be more effective to transmit a tone having a sound color with a stronger warning color than the busy tone.

[0243] This is because the public line signal processing unit sets the other user on-hook immediately after one of the users on the call ends the call and puts the receiver on-hook. An example of an Internet telephone network system characterized by transmitting a sound such as a busy tone to the user from the telephone device adapter of the user to the telephone device to make the user aware of the end of the telephone call is described.

Further, during the IP address transmission / reception processing, even if the use of the telephone is immediately resumed, the use is impossible. As a process of the telephone device adapter, when the IP address transmission / reception process is started, the connection of the public line is not switched to the telephone device until the process is completely completed. In order to notify the user of such a state, the user can hear a sound, such as a busy tone, to warn the user that the call cannot be used even during the IP address transmission / reception processing. If an off-hook operation of the receiver of the telephone device is detected during the IP address transmission / reception processing, the telephone device can transmit a busy tone to the telephone device. As described above, it is possible to emit another tone having a stronger warning color than the busy tone.

This is because the public line signal processing unit holds the connection on the public line without disconnection immediately after both users who are talking end the call and immediately turn on the receiver. While transmitting the address information corresponding to the identification information of the communication device on the side transmitting the call information to the other party transmitting the call information via the public line, either of the two users may receive the call information. Also, when the receiver is off-hook to use the telephone, the calling device adapter of the user sends a call to the calling device to warn the user that the transmission process is in progress and the call cannot be made. An example of an Internet telephone network system is described in which a sound such as a busy tone is transmitted to a user to realize that the call cannot be made.

In the above description, during the IP address transmission / reception processing,
Although the operation of making a telephone call could not be performed, the telephone device adapter can accept only a telephone number input operation from the telephone device. Therefore, instead of listening to the busy tone, the input of the telephone number is accepted as usual, and the communication device identification information of the telephone number is stored.
After the end of the P address transmission / reception processing, a normal telephone call processing can be executed. Since the IP address transmission / reception process does not take several minutes, it is highly likely that the process has been completed sufficiently during the operation of the user to input the telephone number. By doing so, the user can use the telephone without waiting in the IP address transmission / reception processing even if he tries to make another call immediately after the call ends.

[0247] This is because the public line signal processing unit holds the connection on the public line without disconnecting the telephone line immediately after both users on the call end the telephone call and turn on the receiver. While transmitting the address information corresponding to the identification information of the communication device on the side transmitting the call information to the other party transmitting the call information via the public line, either of the two users may receive the call information. When the receiver is off-hook to use the telephone, the input of the identification information of the communication device of the call destination of the user is received and stored, and after the transmission process is completed, the call corresponding to the identification information is completed. An example of the Internet telephone network system characterized by starting the processing of (1) is described.

Up to now, only the registration processing in the IP address table has been described. Next, for the convenience of the user, the registration of the IP address of the call destination once registered is deleted. explain. In the case where a call has already been made, it may be better not to register the IP address of the other party of the call in the first embodiment.
Explanation was made in Section 3. Therefore, when a call was made, it was possible to make settings so that the IP address would not be registered uniformly.
If it is assumed that you will never call the other party after making a particular call, you can cancel the registration of the IP address of the other party immediately after the call . For example, a wrong call, a complaint call from a customer, an inquiry call, or a questionnaire call. In order to realize this function, after the IP address transmission / reception processing after the end of the call, the user picks up the receiver and sets a number indicating the execution of the registration deletion function together with a specific # or * symbol (deletion instruction information). Make the communication device input. Based on this input operation, the public line signal transmission / reception unit 1100 in the communication device adapter deletes the registration of the entry of the IP address table stored immediately before via the telephone number IP address conversion unit 300. In this way, it is possible to delete the registration of the IP address of the other party of the call that is unnecessary for the convenience of the user.

This means that if the public line signal processing unit does not use the next call, such as an incorrect call, when the user makes a call, the public address signal learning unit learns the IP address after the call. An example of an Internet telephone network system characterized in that registration of the address information of the above-mentioned call device of the called party can be deleted by an operation such as button input of the call device.

Embodiment 15 FIG. In the second embodiment,
In S21 of FIG. 4, it is shown that the input of the telephone number is confirmed. In the fifteenth embodiment, the contents will be described in more detail. Since there are various numbers of digits in the telephone number which is the identification information of the communication device, there are several methods for determining whether or not the user has finished inputting the telephone number. Basically, the input operation of one digit of a continuous telephone number is performed at an appropriate time (for example, 0.3 digits).
Every second). Since it is assumed that the time interval rarely exceeds, for example, 5 seconds, it is determined that the input of the telephone number has been completed if there is no input operation at a point in time when a certain set time is exceeded. it can. Since the set time may depend on the user's habit of telephone operation, it is desirable to set an appropriate time for each user. Therefore, the user is allowed to change the set time.

This means that the public line signal processing unit determines whether or not the user who makes the call has finished inputting the identification information of the communication device of the communication destination to be input to the communication device, based on the continuous information of one character per character. An example of an Internet telephone network system in which a state in which an input is not performed even after a lapse of a specific time is detected and performed is described.

In the above description, a standby time for determining input completion of, for example, about 5 seconds has been set. However, it is assumed that some users may not like to wait for such a standby time. . Therefore, when the input of the last number of the telephone number composed of the predetermined character information is completed, in order to notify the end of the telephone number to the communication device adapter side, the characters such as # and * which indicate appropriate ends are terminated. It is also conceivable to adopt a method of inputting information. Needless to say, in combination with the method of inputting the end information, it is possible to automatically determine the end after the elapse of the set time without any input. On the other hand, if the phone number is basically fixed to a predetermined size, for example, a 4-digit telephone number, such as an in-house extension, the extension number must be entered by first inputting 9 or the like first. , And then inputting a four-digit telephone number, it is possible to automatically determine the end of the input operation.

This means that the public line signal processing unit determines whether or not the input of the identification information of the communication device of the communication destination to be input to the communication device by the user performing the communication ends by inputting the continuous information of one character per character. An example of an Internet telephone network system in which the input of a character indicating a specific final input is detected and performed is described.

Further, as the telephone number system, since the communication carrier information determined for each communication carrier (telephone service company) is adopted, the input of this communication carrier information (such as 090 for a mobile phone) is performed. Thus, a method of confirming the number of digits (size) of the subsequent telephone number can be realized.

[0255] This means that the public line signal processing unit determines whether or not the user who makes the call has finished inputting the identification information of the destination communication device to be input to the communication device, by using the higher order identification information (that specifies the telephone company). Confirmation of the input of telecommunications carrier information), the number of digits (size) of the identification information is determined by the number system of the upper identification information of each telephone company, and the final input was made while counting the number of characters to be input An example of an Internet telephone network system characterized in that the Internet telephone network system is detected and performed.

The following describes the high-order identification information for each telephone service company. The telephone service company name is abbreviated. -Higher order identification information A 3 or 4 digit number to be prefixed and dialed when using a telecommunications carrier other than NTT from an NTT subscriber telephone. 2
Since the spring of 001, if you register a telecommunications carrier you usually use in advance, a "telephone priority connection system" will be introduced that allows you to make a call without omitting a 3- to 4-digit identification number.
Following the reorganization of T, this identification number was also assigned to NTT East and NTT West in August 1999 by the Ministry of Posts and Telecommunications. FIG. 40 shows high-order identification information for each telephone service company (communications carrier). However, the company name of the telephone service company (telecommunication carrier) shown in FIG. 40 is abbreviated.

On the other hand, after S21 in FIG. 4 of the second embodiment, the address conversion table is referenced in S22 according to the input telephone number. In this reference processing, there is a method in which all the telephone number information is collected, or a method in which the candidate of the corresponding IP address table entry is narrowed down from the upper digit every time a telephone number is input. Can also be taken.

[0258] This means that the connection destination determination unit performs the conversion process by the address conversion unit on all the identification information input to the destination communication device after determining the end of the input of the communication device. An example of a featured Internet telephone network system is described. Further, the connection destination determination unit may continuously perform the conversion processing by the address conversion unit every time one character of the identification information is input from the communication device of the communication destination after the determination of the end of the input of the communication device. An example of an Internet telephone network system is described.

As described above, when searching for an IP address table entry for each digit of a telephone number, before searching for an entry for all digits,
It is assumed that there are many cases where only one address information candidate remains. In such a case, by ending the IP address conversion processing when there is no other address information candidate, higher-speed processing can be realized.

This means that, after the connection destination determining unit determines that the input of the communication device has been completed, every time one character of the identification information is input from the communication device of the communication destination, the conversion process by the address conversion unit performs the conversion. The potential address information candidates are limited, and when the options are narrowed down to one, the address information candidates are adopted as a final conversion result without waiting for input of all identification information. An example of an Internet telephone network system characterized by the following is described.

If the configuration is not such that the candidates for the IP address table entry are narrowed down by confirming the telephone number one digit at a time as described above, the telephone number of all digits is searched. As an intermediate case between the two,
For example, a method of searching for an IP address table entry when an 8-digit telephone number is input is also conceivable.
As a pre-reading of the search, it is based on the assumption that if the search result is approximately eight digits or so, the search process will be successful. As the number of digits for the look-ahead, various types other than eight digits can be considered. If you often call your company's 4-digit extension,
By performing the search process once at the time of digit input, it becomes possible to realize a comprehensively high-speed determination process. Also,
Also in these prefetching search processes, when a plurality of candidates remain, a more accurate search process can be realized by executing a search for the telephone number added again.

This means that, after the connection destination determination unit determines that the input of the communication device has been completed, every time one character of the identification information is input from the communication device of the communication destination, the conversion process by the address conversion unit performs the conversion. The possible address information is limited, and after the identification information having a specific number of digits is input, when the options are reduced to one, without waiting for the input of all the identification information, An example of an Internet telephone network system characterized in that the address information is adopted as a final conversion result is described.

Embodiment 16 FIG. Here, processing in a case where the present call device adapter is connected to a call device management device such as a PBX or a key telephone device will be described in more detail. FIG. 41 shows a usage form of a plurality of telephone lines by a general PBX or key telephone device. When making a call from a telephone device (telephone) to an area outside the PBX 190, there is no difference in communication processing from the case of using only the conventional telephone device. The telephone number information at the time of the telephone call input to the telephone device is transmitted as it is to the exchange of the telephone office, and the exchange creates a connection with the other party of the call. On the other hand, as shown in FIG.
When a call is received from outside the PBX 190, it is necessary to select a specific communication device in the PBX, so the exchange 192 identifies the plurality of communication devices 10a to 10d supported by the PBX. It is necessary to transmit the information of the lower digit of the telephone number to the PBX side. This PBX1
The method of transmitting and receiving information between the switch 90 and the exchange 192 has a specification determined by the telephone company.

FIG. 42 shows a mode of using a plurality of telephone lines by a telephone device management device to which a telephone device adapter is connected.
In order for the telephone device adapter 22 to support a connection mode with a telephone device management device such as a PBX or a key telephone device, when a call is made from outside the PBX 190,
As the actual communication device management device does, switch 1
It is necessary for the communication device to transmit the lower digit information of the telephone number received from 92 to the communication device management device. At this time, the transmission / reception method between the telephone device adapter 22 and the telephone device management device of the PBX 190 uses exactly the same transmission / reception method between the exchange 192 and the PBX 190. Each telephone company publishes detailed specifications on the transmission / reception method of the lower digit information of the telephone number.

[0265] This means that the public line signal processing unit of the telephone device adapter has a P-P between the telephone device and the telephone device.
When a communication device management device such as a BX or a key telephone device is connected, the identification information for identifying a specific communication device among the plurality of the communication devices connected to the communication device management device is described above. The public line of the intercom adapter,
Alternatively, when a call is received from the IP network, the call is transmitted to the communication device management device,
An example of an Internet telephone network system in which a call device can be specified to make a call is described.

In addition to the transmission / reception processing between the exchange and the general communication device, the telephone company may perform transmission / reception processing for realizing the service in order to provide a special service with the above-described device such as the PBX. is there. In addition to support for PBXs and the like, there is also one related to a number display (number display function). This allows the telephone number of the other party of the call to be displayed on the display device of the telephone device at hand, and transmission / reception processing of telephone number information is performed between the exchange and the telephone device. Basically, the exchange performs a process of transmitting telephone number information to the caller on the other side. In order to realize this in the Internet telephone network system of the present invention, the telephone device adapter connected to the telephone device of the caller temporarily stores the telephone number information transmitted from the exchange, and communicates with the exchange. Similarly, the telephone number information is transmitted to the communication device.

[0267] This means that the public line signal processing unit of the telephone device adapter, when the telephone device has a contract for a number display function (number display function) in a telephone call service on the public line, has a call destination. By transmitting identification information for identifying the communication device of the communication device to the communication device when a call is received from the public line of the communication device adapter or the IP network, the communication device An example of an Internet telephone network system characterized in that it is possible to display the identification information of the other party of the call on the display device of (1).

Since the above service is a service provided by an exchange on a public line, in order to support a similar function on an IP network, the caller adapter of the caller must be connected to the caller adapter of the caller. This can be realized by transmitting the telephone number information of the calling party to the telephone device adapter.

This is because the public line signal processing unit of the telephone device adapter determines that the telephone device of the other party of the telephone call has a contract for a number display function (number display function) in a telephone call service on the public line. When the identification information for identifying the communication device is called from the IP network of the communication device adapter,
An Internet telephone network system wherein transmission information is transmitted to the call device adapter of a call partner, whereby identification information of the call device can be displayed on a display device of the call device of the call partner. An example is described.

Further, regarding the number display function (number display function), by inputting non-notification information which is a special number digit (eg, 184) at the beginning of a telephone number, a telephone call to the destination of a call can be made. Transmission of the number information can be refused. The communication device adapter of the person making a call via the public line only needs to transmit the telephone number including the special number digits entered above to the exchange as it is, so no special communication processing is required. It is necessary for the communication device adapter of the person who can make a telephone call to mediate a rejection communication process for requesting telephone number information between the exchange and the communication device. Further, when making a call via the IP network, if the input of the special number digits is confirmed, the telephone number information is not transmitted to the caller adapter which can make the call. Furthermore, the telephone device adapter of the person who can make a telephone call must reject transmission of telephone number information to the telephone device in the same manner as the communication processing of the exchange.

[0271] This means that the public line signal processing unit of the telephone device adapter determines that the telephone device of the other party of the telephone call has a number display function (number display function) contract in a telephone line service. When making a call from the IP network of the telephone device adapter, the identification information for identifying the telephone device is
When a call is made by adding a number digit for which a number is not notified, by not transmitting the call to the above-mentioned telephone device adapter of the other party of the call,
An example of the Internet telephone network system is described in which the display of the identification information of the communication device of the present invention can be suppressed on the display device of the communication device of the other party of the call.

As for the service relating to the number display function (number display function), since the telephone company discloses the specification of the communication processing method between the exchange and the telephone, the telephone adapter is provided in accordance with the specification. Can implement the above function.

Embodiment 17 FIG. The maintenance setting function described in the fourth embodiment allows the user to set the control information unique to the setting information storage unit. Processing cannot be performed. For example, if the IP address or the netmask of the telephone device adapter is incorrect, all processes for accessing the IP network fail. Therefore, when a clear error of the set value is detected by executing the processing in the communication device adapter, the user is notified of the error of the set value. Means for informing the user include, for example, displaying a warning lamp or a display screen on the telephone device adapter, or indicating a setting error when the receiver is picked up in an attempt to use the connected telephone device. For example, a warning tone is emitted.

[0274] This means that the IP network communication processing unit or the public line signal processing unit allows the user to read the IP network data read / write unit or
As a result of the setting in the telephone device adapter by the telephone input data light unit, when the telephone call processing cannot be executed due to an error in the setting during the entire telephone call processing, a warning is displayed on the display device of the telephone device adapter. A description is given of an example of an Internet telephone network system characterized in that a user can be guided to correct a setting error by making a display indicating the same or transmitting a sound indicating a warning to a connected telephone.

In the above description, an example was given where the set IP address and the like were incorrect for access to the IP network. However, for access to the IP network,
A warning can be issued in the same manner as described above, because the connected router is out of order or the IP network is disconnected, and the IP network cannot be accessed.

This means that the IP network communication processing unit or the public line signal processing unit determines whether the user
In the case where the setting in the communication device adapter is performed by the P network data read / write unit or the telephone input data writing unit, the communication process can be executed due to an error in the setting during the entire call processing. When the IP network connected to the telephone device adapter, or the public line is disconnected, or when the telephone or the IP network device connected to the telephone device adapter is not operating due to failure or stop, An internet telephone network system capable of alerting a user of an abnormality of a peripheral device by displaying a warning on a display device of the telephone device adapter or transmitting a warning sound to a connected telephone; An example is described.

Therefore, the above warning function can also be used because normal IP network access can be resumed when the router failure is restored or the disconnected IP network is newly restored. In
By stopping the conventional warning process and starting the normal process, the user does not have to cancel the warning function.

This means that the IP network communication processing unit or the public line signal processing unit determines whether the user
In the case where the setting in the communication device adapter is performed by the P network data read / write unit or the telephone input data writing unit, the communication process can be executed due to an error in the setting during the entire call processing. The IP network connected to the telephone device adapter, or the public line was disconnected, or the telephone or IP network device connected to the telephone device adapter was not operating due to failure or stoppage. When the state is activated by the recovery processing of the peripheral device, the display indicating the warning is stopped on the display device of the intercom adapter, or the transmission of the sound indicating the warning to the connected telephone is stopped. Internet telephone network, which can notify the user that the abnormality of the peripheral device has been recovered It describes an example of the stem.

Embodiment 18 FIG. In Embodiment 8 described above,
The POST message has been described as a message for sending voice data to the HTTP relay server. However, it is also possible to use a message such as GET or PUT other than POST. However, in the case of GET, since it is basically necessary to embed in a field called URL, there is an upper limit on the data size. Since POST and PUT can have a data body in addition to various fields such as a header, there is basically no upper limit on the size (however, there are cases where there is a restriction due to the implementation of the HTTP proxy, etc.).

When the voice data is acquired from the HTTP relay server in the GET message, the fragmented voice data can be repeatedly obtained by issuing the GET message, but the first size is obtained. Once a GET message for acquiring data of a second size that is sufficiently larger than the voice data of the call time is issued only once, the voice data of the first size is repeatedly cut when the voice data can be captured. It is also possible to obtain.

According to the HTTP specification, the message transmission / reception processing is executed after a connection is first made between the client side and the server side. Basically, there is a necessary processing time to create this connection, so basically in real-time audio data transmission / reception processing, once a connection is created once to improve performance, the connection is It is desirable to transmit and receive audio data while holding the data. However, since a network node such as an HTTP proxy is generally interposed between the client side and the server side, the connection may be disconnected regardless of the convenience of the client side and the server side due to a relay condition. There is also. In such a case, a new connection is made to restart the transmission / reception processing of the audio data.

In addition to the HTTP, the present communication device adapter and the HTTP relay server use the TCP
Communication on the P network. TCP is a connection-type communication protocol, and it is necessary to establish a connection before transmitting and receiving data. In the communication processing by the TCP, data transmission / reception may be delayed for a long time or the connection may be disconnected due to some cause on the IP network. In such a state, the processing of the program is stopped. Therefore, all the processing for transmitting and receiving data via the IP network is set to a fixed time-out value, such as waiting for a reply from the communication partner. If there is no response even if the timeout value is exceeded in the processing, a new connection is made and the access processing of the IP network is restarted from the beginning, so that a hangout of the system can be avoided.

[0283] This means that after the communication device adapter makes a connection to the HTTP communication processing unit of the relay server in order to transmit a voice data packet,
An example of an Internet telephone network system in which voice data is stored in a message of a method such as GET, POST, and PUT specified by TTP in an encoded format and transmitted is described.

Also, this means that the communication device adapter
After performing connection to the HTTP communication processing unit of the relay server in order to receive a voice data packet, voice data is encoded in a response message of a message of a method such as GET defined by HTTP after encoding. An example of an Internet telephone network system characterized in that the Internet telephone network system stores and receives data in the Internet is described.

This also means that the communication device adapter
After performing connection to the HTTP communication processing unit of the relay server in order to receive a voice data packet, a message of a GET method specified by HTTP is used to reduce the size of voice transmission / reception data of a telephone act. Make sure to acquire data of a sufficiently large size, store the audio data in the data format of the response message in an encoded format, and continuously receive the audio data as fragments each time the audio data is generated. An example of a featured Internet telephone network system is described.

This also means that the communication device adapter
A connection is made to the HTTP communication processing unit of the relay server to transmit and receive voice data packets,
After sending and receiving the message of each method and its response message, do not immediately disconnect,
An example of an Internet telephone network system that transmits and receives a message of each method and a response message thereof is described.

[0287] This also means that the communication device adapter
A connection is made to the HTTP communication processing unit of the relay server to transmit and receive voice data packets,
If the connection is disconnected for some reason during or immediately after sending or receiving the message of each method or its response message, reconnect and continue the message of each method or its response An example of an Internet telephone network system that transmits and receives messages has been described.

This also means that the communication device adapter is
A connection is made to the HTTP communication processing unit of the relay server to transmit and receive voice data packets,
During or immediately after sending or receiving a message of each method or its response message, if there is no response to the HTTP or TCP transmission / reception processing even after a certain period of time elapses for some reason. An example of an Internet telephone network system in which a connection disconnection process is performed, a connection is made again, and a message of each method and a response message thereof are continuously transmitted and received is described.

Embodiment 19 FIG. In the above-mentioned Embodiment 8, referring to FIG.
Allows access to the administrative area of the other party in the call,
It has been checked whether the user is already on the phone (S75). In the nineteenth embodiment, an identifier, which is call connection identification information, is given to a call act itself (this identifier is referred to as a session ID). When making a call using the HTTP method, first, When it is determined that a call can be made at the time of inquiring of the HTTP relay server whether the call can be made, the
The TP relay server assigns a session ID to the call and confirms that the call can be made. (Basically, the session ID only needs to be generated incrementally by the counter.) Based on the session ID, the HTTP relay server manages information about the call. If the caller adapter on the user side also acquires this session ID as call permission, transmission / reception of voice data to / from the HTTP relay server can be distinguished from other calls while referring to the session ID. In the HTTP relay server, the source of the session ID, information about the call,
For example, management can be performed by recording log information such as identification information, IP address information, call time, call start time, and call end time of both communication devices of the call. It is also possible to perform a charging operation based on such management information.

This means that the relay server manages session information, which is a set of address information of the communication device adapters of both users when the user makes a call, as call connection identification information, and stores the information in the voice data packet. An example of an Internet telephone network system in which the call connection identification information is stored and transferred on an IP network has been described.

[0291] This also means that the relay server uses the session information, which is a set of address information of the communication device adapters of both users when the user makes a call, as the call connection identification information, so that the user's call can be made. An example of an Internet telephone network system is described in which a call time, a communication packet amount, and the like can be stored and taken out as log information every time it is executed.

Embodiment 20 FIG. In the twentieth embodiment, when a telephone call is received from a third party in another system during a telephone call via a public line, a call via UDP over an IP network, and a call via HTTP. A communication device adapter provided with a processing method for notifying the busy state will be described. Already in Embodiment 6,
A description has been given of the form of the call processing in which the public line, the UDP, and the HTTP coexist. Also, in Embodiment 8,
The procedure for making a call using the HTTP method has been described. Here, the procedure for making the call is SMT
P (simple mail transfer pr
The case of using a telephone call method using e-mail according to an O.T.

FIG. 43 shows a case where a call is received from a third party while a call is being made by the above three methods.
There are nine patterns shown in FIG.

As described in FIG. 43, the process of notifying the busy state basically outputs a busy tone to the third party communication device. If the telephone call from the third party is via the public line, besides transmitting the busy tone directly from the telephone company exchange, the telephone equipment adapter that made the telephone call generates a busy tone and transmits it via the public line. I do. However, in the case of the latter, the telephone is only informed of the busy state and the telephone is in a call state, so that a telephone charge is paid to the telephone company. If the telephone call from the third party is UDP, the busy state is reported from the telephone equipment adapter that made the telephone call, so the third party telephone equipment adapter itself generates a busy tone and provides the user with a busy tone. I try to hear that sound. Phone calls from third parties are HTTP
In the case of (3), if it is determined by the inquiry to the HTTP relay server that the telephone is busy, the third party communication device adapter itself generates a busy tone so that the user can hear the sound.

In the above-described method, even when three types of telephone communication methods are mixed, it is possible to report a busy state in response to a telephone call from a third party. However, in order to simplify the implementation of the communication device adapter and the like, it is possible to omit the report of the busy state as described above. In this case, even if the third party calls the telephone, the third party feels that the other party will not answer the telephone forever, and gives the user a sense of discomfort compared to the existing telephone usage. It will be.

[0296] This is because the IP network communication processing unit or the public line signal processing unit uses the communication method of the public line communication, the RTP communication process, or the HTTP communication process to make a call. In addition, when the third user makes a telephone call using any of the above-mentioned calling methods, a busy tone is transmitted to the third user's calling device to notify the busy state. An example of an Internet telephone network system characterized by what can be done is described.

[0297]

As described above, the above-described embodiment, which has described one example of the Internet telephone network system of the present invention, has the following effects.

When a call can be made via the IP network when a call via the IP network is possible, the telephone number cannot be converted to an IP address, or when the other party's communication device is not connected to the IP network If a call on the IP network is not possible, for example, if the call device adapter connected to the call device of the other party is a device that is incompatible with the call device adapter on the transmission side, a public line network There is an effect that you can make a call via.

[0299] Further, there is an effect that a user can make a call via an IP network using a conventional telephone number as it is.

Also, when call information is received as digital voice data from the IP network, the voice information can be transmitted as analog voice data to the telephone device.

[0301] Further, when the call information is received as analog voice data from the telephone device, there is an effect that the voice information can be converted into digital voice data and transmitted to the IP network.

[0302] If the communication device of the other party to which the call information is transmitted can communicate via the IP network, a call can be made from the IP network side. By making a call, both can be automatically switched. For this reason, the caller can use the public line,
There is an effect that call information can be transmitted and received via any of the P networks.

After making a call via the public line, the telephone number of the user's own communication device and the IP address corresponding to the telephone number are notified to the other party's telephone number, or the telephone number of the other party's communication device is used. Is provided with an IP address learning unit that receives an IP address corresponding to the IP address, so that the caller does not need to check the IP address of the other party in advance and set the address conversion table.

Also, the conventional general public line telephone number and I
Storing the P address in a corresponding manner has an effect that a telephone call can be automatically made via the IP network after the next telephone call.

Also, since two or more voice data other than the own voice received via the IP network from another telephone device to which the telephone device adapter of the present invention is connected are mixed to output a voice. There is an effect that three or more callers can hold a telephone conference via the IP network.

Also, a conference identification number is set for the telephone conference,
Since the conference identification number is specified by the caller who requested the call at the time of the call request, there is an effect that a telephone conference via the IP network can be performed between the specified participants.

[0307] Also, a telephone identification number is set to the telephone device to which the telephone device adapter is connected, and the telephone identification number is specified by the caller who has requested the telephone call at the time of the telephone call request. This makes it possible to hold a telephone conference via the IP network.

Also, by assigning a password to each caller scheduled to participate in the telephone conference in advance, managing each telephone call, and inputting the password of each caller at the time of participating in the telephone conference, the password can be compared with the password registered in advance. Collation can be performed, and there is an effect that telephone conference participants can be authenticated.

Also, the control information generated for the maintenance work can be input from the existing telephone, a telephone, or a general-purpose personal computer connected to the telephone adapter, and the setting information storage unit is stored in accordance with the input control information. Since the control information stored in is changed.
This has the effect of reducing the cost of adding a data input / output device dedicated to maintenance work to the communication device adapter. In addition, there is an effect that a user or the like can easily perform maintenance setting work using a conventional device (a communication device that is an existing telephone or a general-purpose personal computer).

[0310] In addition, since permission information regarding a telephone conference can be entered and registered from a telephone connected to the telephone device adapter or a personal computer connected to the IP network, the occurrence of new registration, change or deletion of registered information, and the like can occur. There is an effect that the work of changing the registration of the permission information regarding the telephone conference which is considered to be frequently performed can be easily performed.

[0311] Further, since UDP and RTP, which are excellent in real-time characteristics of communication processing, are used, there is an effect that the voice quality of a call can be improved.

[0312] For a firewall that does not allow the use of an arbitrary UDP port, a very limited specific UD is used.
By setting the firewall so that the P port can be used and storing the specific UDP port number in the communication device adapter, there is an effect that voice data communication processing over the firewall can be performed.

Further, since it is possible to scan a usable UDP port for a firewall that does not permit the use of an arbitrary UDP port, even if the available UDP port is unknown, it can be scanned. There is an effect that it is possible to search for and perform communication processing of audio data.

[0314] Although a firewall often cannot use a UDP port, the HTTP port is normally open, so voice data is transmitted as an HTTP message. For this reason, there is an effect that call processing via an IP network can be realized even for a robust firewall.

[0315] Further, when the telephone adapter makes a call via the IP network, there is an effect that voice data can be transmitted and received by TCP.

[0316] Further, when the telephone adapter makes a call via the IP network, there is an effect that voice data can be transmitted and received by HTTP.

[0317] Also, when the telephone device adapter makes a call via the IP network, security that prohibits illegal access to the boundary from the IP network region to which the telephone device adapter is connected and managed to the external IP network region. Investigating the existence of an HTTP port capable of transmitting and receiving data to a firewall for the purpose of
There is an effect that the P port is specified, and voice data communication can be performed using the HTTP port.

Also, unique compression is performed on the header of the packet of the audio data to be communicated. Therefore, the packet size can be made smaller than the standard packet size, and there is an effect that network traffic can be reduced. Also, since the packet of the compressed audio data can be decompressed, it is possible to receive the compressed packet information. This has the effect of reducing network traffic.

Also, even if the transmission time of each packet of the audio data to be communicated fluctuates, the data is accumulated until a certain size is received at the time of reception and sent to the analog playback side, so that the network traffic situation is not good. There is an effect that a stable communication quality can be maintained even when the communication is stable. Also, I
When transmitting a digital voice data packet to a destination telephone via the P network, a digital voice data packet to be transmitted is created and stored in a transmission buffer whose buffer size can be changed and data required before transmission. It has a transmission buffering unit that performs a process of adding only the packet data to the packet assembly, so that an optimal digital voice data packet transmission mode can be realized according to network traffic conditions, and there is an effect that high quality voice data transmission can be performed.

In transmitting each packet of voice data to be communicated, the packet size is reduced when the amount of network traffic is small, and the packet size is increased when the amount of network traffic is increased. Even if the situation is unstable, there is an effect that a stable call quality can be maintained without affecting network traffic.

Further, since a redundant packet can be issued when a packet loss frequently occurs during transmission of each packet of voice data to be communicated, even in a situation where network traffic frequently causes a packet loss, This has the effect of maintaining stable call quality.

Also, when transmitting each packet of voice data to be communicated, if the amount of network traffic increases, the transfer of voice data packets that do not affect call quality under conditions such as a certain volume level or less is not performed. As a result, there is an effect that stable communication quality can be maintained even when the amount of network traffic increases.

Also, the reception timing of each packet of the audio data to be communicated is measured, the network traffic situation is estimated, the size of the reception buffer is adjusted, the number of packet information to be duplicated by the redundant packet issuing unit is adjusted, Since at least one of the conditions for reducing the number of packet information transmitted by the generation filtering unit is adjusted, optimal communication processing can be performed according to the latest state of network traffic, This has the effect of maintaining stable call quality.

Since the result of measuring the reception timing of each packet of the voice data to be communicated is accumulated and can be referred to as data indicating the network traffic status in a cycle such as one day or one week, the average is obtained. It is possible to perform optimal communication processing control corresponding to various network traffic conditions, and to maintain stable communication quality.

Also, since the firewall is capable of accessing the external Internet via HTTP, the telephone adapter can perform telephone calling and telephone call processing via the HTTP relay server. Thus, there is an effect that it is possible to make a call via the IP network without having to change any settings. Also, it is possible to temporarily hold the voice data in the HTTP relay server, and to realize a call process by a call device adapter connected to another telephone requiring the voice data to obtain the voice data. There is an effect that can be done. In addition, when it is determined that the communication device adapter of the communication destination is blocked by the firewall, the communication device always reports HTTP calls to the communication device adapter of the communication destination at an appropriate time interval. For the relay server, the telephone call status of the telephone device adapter of the telephone call destination in the telephone call information management unit in which the telephone call status of each telephone is stored is set to H.
Investigation by the TTP polling unit has the effect that, when it is determined that a telephone call is being made, the called device adapter can make a call via the HTTP relay server by HTTP access. In addition, when it is determined that the call device adapter of the call destination is blocked by the firewall, the public line signal processing unit reports the call to the call device adapter of the call destination by a public line signal processing unit. Only the telephone call information is transmitted via the temporary public line, and the called telephone adapter is HTT
There is an effect that a call can be made via the HTTP relay server by the P access, and the call information can be mutually exchanged via the HTTP relay server.

[0327] In the HTTP relay server, after the first connection negotiation process with each of the communication device adapters, the
The TP connection changing unit changes the connection between HTTP and TCP so that the connection is directly between the two adapters. After the processing of the connection negotiation between the first communication equipment adapters, the transmission and reception of the communication data is performed. However, since the processing load becomes considerably heavy, the transmission and reception of the communication data is performed directly without passing through the HTTP relay server. If the communication is performed between the two communication device adapters, the processing load on the HTTP relay server is reduced,
Even if many users make a call and call processing is concentrated, the processing can be continued without delay, and there is an effect that call quality can be maintained.

Further, since the transmission and reception of the call data is performed directly between the two communication device adapters without passing through the HTTP relay server, the processing load of the HTTP relay server is reduced, so that many uses are possible. Even if a call is made and a call is concentrated, the process can be continued without delay,
This has the effect of maintaining call quality.

The transmission and reception of the call data is performed on the HTTP relay server as a process on the HTTP relay server.
Since the IP address of the P header portion and the port number of the TCP header are directly converted into the IP address and port number of the final destination communication device adapter, the processing load on the HTTP relay server is reduced, so that many Even if the user makes a call and the call processing is concentrated, the processing can be continued without delay and there is an effect that the call quality can be maintained.

Even if efficient communication processing is performed in the HTTP relay server, if one user increases the number of telephone device adapters requesting call processing, then one HTTP
Since the TTP relay server has a limit in processing performance, it will eventually fail. Therefore, a plurality of HTTP relay servers are prepared, an HTTP relay server management server that integrally manages the plurality of HTTP relay servers is provided, and an HTTP relay server with a small number of users currently available is identified, and a candidate used in the call processing is determined. Specify the HTTP relay server. By distributing the call processing of each call device adapter to the plurality of HTTP relay servers, there is an effect that each user can maintain a comfortable call state.

Also, the name of the communication device adapter is used as an identifier of the communication device adapter which is previously grasped between the communication device adapters transmitting and receiving the communication information. For this reason, the telephone adapter can be used in a network form in which the IP address is not fixed and is dynamically given. In the case where an IP address is dynamically assigned, a DHCP server may be required to provide an IP address, or a telephone device adapter may make a dial-up connection to an Internet service provider (ISP) and have an IP address assigned at the time of connection. In some cases, even if a fixed IP address is not assigned,
There is an effect that the connection negotiation process with the communication partner of the communication device adapter can be realized.

[0331] The Internet telephone can be used by making a dial-up connection to an Internet service provider (ISP) at a necessary point in time, not in a network environment that is always connected to the IP network. In other words, there is an effect that an Internet telephone can be used by a dial-up connection that can be relatively easily performed in an ordinary home without the user having to set up or make a contract for a constant connection mode.

[0332] Further, a dial-up connection is made to an Internet service provider (ISP) at a necessary point in time, not in a network environment that is always connected to the IP network.
Use the popular terminal adapter for personal computers. The terminal adapter has a built-in device for communicating with a public line or ISDN such as a modem. By providing an RS232C serial port processing device that can be easily mounted in the communication device adapter, the relatively large cost device is left to the terminal adapter, thereby reducing the cost of realizing the communication device adapter. There is.

[0333] Even if both parties who are talking using the communication device end the communication and put down the handset of the communication device, the communication device adapter keeps the connection of the public line. Has the effect of being able to send and receive

[0334] Also, when a call is being made using the communication device, the other party transmitting the call information after a predetermined time has elapsed after the end of the call and the side transmitting the call information hangs up the receiver. Sends a tone signal notifying the disconnection. For this reason, since the caller adapter keeps the connection of the public line in a state where the call of the caller is completely terminated and both handsets are placed, the transmission and reception of the IP address information can be performed reliably. is there.

Also, since a voice such as a busy tone for notifying the end of the call is generated to the other party transmitting the call information, the other party transmitting the call information can surely know the end of the call. Yes, there is an effect that the receiver can be placed.

[0336] Further, if the user tries to use the communication device while transmitting / receiving the IP address information, the user can hear a voice such as a busy tone from the receiver. Therefore, the user should not use the communication device while transmitting / receiving the IP address information. There is an effect that can be.

When the user tries to use the communication device during transmission / reception of the IP address information, the input of the identification information of the communication partner is accepted, and when the transmission / reception of the IP address information is completed, the received identification information is received. Perform the process of connecting to the destination. Also, the transmission / reception processing of the IP address information does not take several minutes. For this reason, a user who intends to make a call can use the communication device without waiting, which has the effect of improving convenience.

[0338] The determination of the end of the input of the identification information is made when no input is made even after a certain time has elapsed. For this reason, the user who makes the call can omit inputting information for determining the end of input of the identification information, which has the effect of improving convenience.

[0339] Further, the determination of the end of the input of the identification information is made by inputting specific information. For this reason, the end of the input can be reliably determined, and the identification information can be input accurately.

[0340] The determination of the end of the input of the identification information is performed by specifying the size of the identification information input by the communication carrier information and comparing the specified size of the identification information with the size of the input identification information. To do it. For this reason, the user making the call can input the identification number in the same manner as in the related art, and the input of the identification information can be surely completed, thereby improving the convenience.

After the input of the identification information is surely completed, the address conversion processing is performed by the address conversion unit. For this reason, the obtainable IP address information becomes accurate information, which has the effect of increasing the reliability of the Internet telephone network system.

Every time one-character information is input as identification information, the address conversion unit narrows down candidates. Therefore, there is an effect that the process of converting the identification information into the IP address can be performed at high speed.

When the number of candidates is reduced to one during the narrowing down of the candidates, the processing by the address conversion unit is terminated. Therefore, there is an effect that the process of converting the identification information into the IP address can be performed at high speed.

If the character information constituting the input identification information exceeds a predetermined number, the address conversion unit converts the character information into IP address information based on the character information. For this reason, since the conversion to the IP address is performed without waiting for the completion of the input of all the identification information, the processing can be performed at a high speed.

The learning process by the IP address learning unit is performed on both the calling party and the called party. For this reason, it is possible to learn without being aware of the identification information and the IP address information of the other party just by making a call, and it is possible to provide a highly convenient Internet telephone network system.

Further, it is possible to prevent the learning processing by the IP address learning unit from being performed when a call is made. For this reason, when the calling party calls for the purpose of sales, for example, the identification information of the other party and the IP
Since it is possible to prevent the address from being registered, it is possible to prevent an unnecessary use of the storage area of the address conversion table.

[0347] Further, it is possible to prevent the calling party from performing the learning process by the IP address learning unit of the other party's communication device adapter when a call is made. For this reason, it is possible to prevent the other party from performing the learning process due to the convenience of the calling party, and thus it is possible to provide an Internet telephone network system that is highly convenient for the user.

[0348] Further, the user can delete information registered in the address conversion table. Therefore, there is an effect that the storage area of the address conversion table can be effectively used.

When the control information is erroneously corrected, the user is notified that the communication device adapter cannot operate normally. Since the user who has received the notification can correct the control information immediately, there is an effect that an Internet telephone network system highly convenient for the user can be provided.

[0350] Further, the user is notified that a call cannot be made due to a line failure. Therefore, there is an effect that the user can immediately know the state in which the call cannot be made.

[0351] Further, when the communication device changes from an unusable state to a usable state, the user is notified that the communication apparatus can be used. For this reason, the user can immediately know that it has become available for use, and this has the effect of providing a highly convenient Internet telephone network system for the user.

If a connection request is made by a third party while a call is being made through one of a public line communication, a RTP communication processing, and an HTTP communication processing, the third party is notified. On the other hand, the state of busy is notified. Therefore, there is an effect that an Internet telephone network system that is highly convenient for the user can be provided.

Also, the relay server assigns session information, for example, a session ID to a call activity. Then, it transmits the session information in the packet information for transmitting the call information. For this reason,
The relay device has the effect of managing the content of the call using the session information in the packet information.

The relay server manages the contents of the call using the session information. For this reason, the relay server can perform, for example, a billing operation based on the contents of the call managed by the relay server.

Further, the communication device adapter performs HTTP access to the relay device using at least one of GET, PUT, and POST methods. Therefore, there is an effect that an access can be performed as if the relay server were a Web server.

Further, the relay server returns the call information in a response message to the request using the method. For this reason, the communication device adapter has an effect of receiving the call information from the relay server by the HTTP access in which the relay server is regarded as a Web server.

When receiving call information by accessing the relay server from the call device adapter, a method for receiving call information having a size sufficiently larger than actual call information is issued. Therefore, there is an effect that the call information can be repeatedly received every time a call is made and the call information is generated.

The connection between the communication device adapter and the relay server is continued even after the transmission of the message for requesting the call information and the reception of the message responding to the request are completed. . Therefore, the processing time required for the connection between the communication device adapter and the relay server can be saved, and there is an effect that real-time transmission and reception of the communication information can be performed.

In addition, the connection between the communication device adapter and the relay server once connected may be unintentionally disconnected. In this case, since the connection is made again, there is an effect that the user can receive the call information from the relay device without being aware of the disconnection.

When no response is received from the relay server even after the lapse of a predetermined time, the connection is once disconnected and then reconnected. Therefore, there is an effect that the user can receive the call information from the relay device without being conscious of the state of the relay server.

Further, the identification information is notified to the communication device management device to which the communication device adapter is connected.
For this reason, the communication device management device has an effect that a predetermined communication device can be specified from a plurality of managed communication devices.

[0362] Also, a call is being made via a public line.
The telephone device adapter notifies the telephone device having the number display function of the identification information. Therefore, the communication device having the number display function has an effect that the identification information of the communication partner can be confirmed.

Also, even when a telephone call is being made via the IP network, the telephone device adapter notifies the telephone device having the number display function of the identification information. For this reason, there is an effect that the identification information of the other party can be confirmed even if the user is making a call via the IP network.

Also, non-notification information for instructing not to display a number is included in the identification information. For this reason,
When the non-notification information can be confirmed in the identification information, the communication device adapter can not notify the other party of the call of the identification information, thereby improving the convenience of the user.
