Next, the operation will be described with reference to the flow charts of FIGS. For ease of explanation, the telephone 10 and the telephone device adapter 12 shown in FIG. 1 will be described as the side for making a call, and the telephone set 20 and the telephone device adapter 22 will be described as the side for receiving the telephone. First, when the power of the telephone device adapter 12 is turned on (S10), the public line signal transmitting / receiving means 1100 and the IP network communication processing means 5 are connected.
000 is used to check whether or not another telephone call is made (S11). In the case of calling from the public line side (S12), the public line signal transmitting / receiving means 1100 transmits the ringing tone from the telephone set 20 input from the public line 13 to the telephone set 10 as it is, and waits until the handset of the telephone set 10 is picked up. (S13). When the handset of the telephone 10 is picked up or the call from the telephone 20 ends (S14), the process returns to S10. If the handset is picked up (S1
4) Then, the call is maintained as it is on the public line and the call is continued until it is disconnected (S17). On the other hand, in the case of a call from the IP network side, the public line signal transmitting / receiving means 1100
Transmits a ringing tone to the telephone 10 and waits until the handset is picked up (S17). If the handset is picked up, the call continues on the IP network as it is until the call is disconnected (S18).

The processing procedure of S18 will be described in detail with reference to the flowchart of FIG. In FIG. 7, S1
At 000, the IP network communication processing unit 5000 determines whether there is received data from the IP network 14. If there is no received data, the process ends. When there is received data (the received data (digital voice data) input from the IP network 14 is packet information), the IP header is removed from the data received by the IP network communication processing means 5000 ( S1001). Next, the IP network communication processing means 5000 further removes the header of the communication protocol from the data from which the IP header has been removed (S100).
2). Then, the obtained digital audio data is decompressed (decoded) (S1003). Next, the audio data digital-analog conversion means 500 converts the digital audio data decoded in S1003 into analog audio data. Then, the IP network communication processing means 5000
Sends the analog voice data converted by the voice data digital-analog conversion means 500 to the public line signal transmitting / receiving means 1100, and the public line signal transmitting / receiving means 1100.
Transmits the sent analog voice data to the telephone 10 (S1005). After the analog voice data has been transmitted to the telephone set 10, the process returns to S2000 in FIG. 6 to continue the call process in order to determine whether or not to continue the call. As for the call state described in S18 of FIG. 5, as shown in FIGS. 6 and 7, the analog voice data from the telephone 20 is converted into digital voice data by the voice data analog-to-digital conversion means 600 provided in the telephone device adapter 22. IP
Sent to network 24, while Internet /
The digital voice data transmitted from the telephone set 20 via the intranet 16 is converted into analog voice data by the voice data digital-analog conversion means 500, and the process of transmitting to the telephone set 10 is continued.

Now, returning to the beginning, when there is no call from others (S11), the public line signal transmitting / receiving means 1100 confirms whether or not the handset of the own telephone 10 has been picked up (S20). At this time, if the handset is not picked up, the process returns to the first step (S10), but if it is picked up, the public line signal transmitting / receiving means 1100 sends a tone to the telephone set 10 indicating that the telephone number has been entered, and the telephone is called. Confirm that the number is input (S21). The input telephone number is converted by the telephone number IP address conversion means 300.
The IP address of the destination telephone 20 is obtained by referring to the address conversion table based on the telephone number (S22). IP
If the address is correctly obtained (S23), the connection destination determination means 200 generates route selection information so as to transmit / receive the call information via the IP network, and the line connection switching means 100 activates the IP network communication processing means 5000. To do. The IP network communication processing means 5000 sends a digital signal for calling the telephone 20 of the other party, enters the call state after the handset is picked up, and continues the call until it is disconnected (S24). Detailed processing of S24 of FIG. 4 will be described with reference to FIG. In FIG. 6, S2000
Then, it is confirmed by the IP network communication processing means 5000 whether the handset of the telephone 10 is placed and disconnected. Then S
In 2001, it is confirmed whether there is a voice input for the set time from the telephone 10. When there is a voice input for the set time, the voice data analog-to-digital converter 600 converts the input analog voice data into digital voice data. The IP network communication processing means 5000 collects voice data at a predetermined fixed sampling time,
The voice data collected within the sampling time is converted from analog data to digital data, and the digital voice data is transmitted to the telephone 20 of the other party. The converted digital voice data is passed to the IP network communication processing means 5000, and the voice data is compressed (encoded) (S20).
03). Then, the IP network communication processing means 500
For 0, the header of the communication protocol is added to the encoded voice data body (S2004), the IP header is further added to the above data (S2005), and the generated data is added to the IP.
It is sent to the network 14 (S2006). Next, the process proceeds to S1000 in FIG. 7 for confirming that the telephone 20 returns the call information via the IP network 24. Since the processing of FIG. 7 has already been described in the detailed processing of S18 of FIG. 5, the description of the processing of FIG. 7 is omitted here. If the IP address is not correctly obtained, the connection destination determination unit 200 generates route selection information so that the call information is transmitted and received via the public line, and the line connection switching unit 100 switches the line connection to the public line 13. The public line signal transmitting / receiving means 1100 is activated. Public line signal transmitting / receiving means 1100 is a public line 1
From the public line 13 to the telephone corresponding to the telephone number input from the telephone 10 via 3 (S25), until the other party picks up the telephone, the public line becomes in a call state and is disconnected. Continue the call (S3
0). In the flowchart of FIG. 4, the processing when the telephone receiver 20 of the other party is not picked up is omitted.
In this case, it disconnects itself and returns to the beginning of the process (S10).

FIG. 9 is a block diagram of each means showing the telephone device adapter of the present invention. In FIG. 9, reference numeral 1100 is a public line signal transmitting / receiving means for making a call via a general public line and transmitting IP address information to each other when disconnected.
0 is an IP which is provided in the connection destination determining means 200 and which gives the public line signal transmitting / receiving means 1100 an instruction to obtain an IP address corresponding to the conventional public telephone number from the telephone device adapter connected to the telephone of the other party. It is an IP address learning unit that is an address learning unit.

Next, the operation of the telephone device adapter shown in FIG. 9 will be described with reference to the flowcharts of FIGS. 10 and 11. The entire processing for making a call is the same as that of FIGS. 4 and 5 of the first embodiment (S10 to S30 of FIGS. 4 and 5).
Is the same processing as S10 to S30 in FIGS. 10 and 11 and FIGS. 4 and 5 are different from each other in that when the telephone cannot be called from the telephone 10 on the side of the IP network, the telephone device adapter connected to the other telephone from the telephone 10 after disconnection is of the same type. The process of transferring the IP addresses to each other after confirming that they are the same is added. Similar processing is added for both cases where a call is made from here and when a call is made.

First, in the former case (when a call is made from the telephone set 10), after the call through the public line is completed (S2

At this time, if the telephone device adapter of the other party's telephone is not a telephone device adapter compatible with the telephone device adapter of the configuration shown in FIG. 9 (S41), after waiting for a prescribed time, the telephone device of the other party is connected. Since there is no response from the calling device adapter, the process ends. If the telephone device adapter connected to the telephone device of the other party is the telephone device adapter of the same type (S41), there is a response from the telephone device adapter connected to the telephone of the other party, and therefore the IP address learning means 400 is public. Line signal transmitting / receiving means 1100
First, it instructs the telephone device adapter connected to the other party's telephone to transmit this IP address in the tone of the analog signal (S42). The own IP address is stored together with its own telephone number in the address conversion table 302, for example, and the public line signal transmitting / receiving means 1100 refers to the address conversion table 302 to obtain the IP address for the own telephone number. Alternatively, the IP address learning means 400 may refer to the address conversion table 302 to acquire the IP address for its own telephone number, and pass the acquired IP address to the public line signal transmitting / receiving means 1100. Next, the IP address is transmitted from the communication device adapter of the call destination, the public line signal transmitting / receiving means 1100 receives the IP address, and the public line signal transmitting / receiving means 1100 causes the IP address learning means 400 to receive the received IP address. hand over. The IP address learning means 400 stores the received IP address in the address conversion table 302 in association with the telephone number of the destination telephone (S4).

In the latter case (when a call is made), after the call via the public line is completed (S30), is there a compatibility between the call device adapter of the caller's telephone and the call device adapter? Is transmitted, the public line signal transmitting / receiving means 1100 receives the tone signal transmitted from the telephone device adapter connected to the other party's telephone, and returns the response tone signal within the prescribed time ( S50). When the inquiry tone does not arrive from the partner telephone device adapter, the process returns to S10.
After returning the tone signal, the IP address of the other party is transmitted from the communication device adapter of the other party, so the public line signal transmitting / receiving means 1100 receives the transmitted IP address and learns the received IP address. Means 4
Pass to 00. The IP address learning means 400 stores the telephone number of the other party and the IP address in the address conversion table 302 in association with each other. The telephone number of the other party is transmitted together with the IP address, or when the telephone of the other party is called, the telephone number of the other party's telephone is acquired, and the public line signal transmitting / receiving means 1100 or the IP address learning means 400 is acquired. It is to be stored temporarily. Next, IP
The address learning unit 400 acquires the telephone number of its own telephone and the IP address corresponding to the telephone number from the address conversion table 302, and the public line signal transmitting / receiving unit 1100.

In some cases, the process of S3001 that adds a new caller to the current call process is added. In a conference call, when a call is first made between two parties via an IP network, and if a third party makes a call to one of the former two parties via an IP network, the third The person and the person are in a call. Further, the same is true even if a telephone call is made from the fourth person and thereafter. In the process of confirming participation by the third party and thereafter, two or more voice data other than one's own voice received from another telephone connected to the same type of communication device adapter via the IP network is used as the voice data mixing means 700. To mix and output audio. For example, the call voice of the telephones 20 and 30 mixed by the voice data mixing means 700 of the telephone device adapter 12 is output to the caller of the telephone 10.

In this embodiment, the voice data mixing means 700 is prepared in the telephone equipment adapter, but as another mode, the voice data mixing means 700 is provided.
A configuration is also possible in which one device mixes and transmits the voice data of other participants excluding the voice uttered by itself to the other telephone device adapter device. In this case, it is not necessary to provide the voice data mixing means 700 in another communication device adapter.

In the procedure for confirming the participation in the above-mentioned telephone conference, it was the procedure for confirming whether or not the third party or later parties are participating while the two parties are talking on the telephone. No processing was performed in this procedure to confirm whether or not participation in the call to the conference held by three or more parties was permitted. However, if the call between the three parties is merely a notification of communication items or a call about small talk, it is not necessary to confirm whether the participating callers are authorized callers, but a conference is held. It is necessary to confirm whether the call is for permission to participate in the call. Therefore, in the third embodiment, in order to confirm whether or not the person who is permitted to participate in the call, an identification number is attached to the conference, and the caller can use one of the permission information before starting the call. A method of inputting a certain conference identification number and determining whether the input identification number is correct. There are three ways to check whether the phone is allowed to participate in the call and how to confirm that the entered password is the correct password by entering the password that is another permission information before starting the call. A method can be considered. 3 above
Each of these methods will be described below one by one.

First, a method of setting an identification number in a telephone conference will be described. An identification number is set for each conference call, and the set identification number is stored in advance in the permission information storage unit 855. However, the identification number of the conference call is not stored in all the permission information storage units 855 included in the communication device adapters connected to the telephones that participate in the conference call, but the organizer who hosts the conference call. It is stored only in the permission information storage unit 855 of the telephone device adapter connected to the telephone. The telephone device adapter connected to the organizer's telephone then confirms whether or not the person can participate in the conference call. The IP network communication processing means 5000 of the caller adapter of the sponsor is the IP network 14
When there is a call request, the conference call identification number management means 80
Notify 0 that there was a call request. Upon receiving the notification, the conference call identification number management unit 800 notifies the telephone requesting the call of the message by voice data to prompt the user to enter the conference call identification number. Then, when the identification number of the conference call is input from the telephone of the called party, the IP network communication processing unit 5000 receives the identification number and notifies the conference call identification number management unit 800 of the received identification number. To do. Telephone conference identification number management means 8
00 refers to the permission information storage unit 855, and confirms 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 means 800 outputs a message permitting a call via the IP network communication processing means 5000. The call permission message is a message that the other party's caller can hear by voice. If the notified conference call identification number is a number that is not set in the permission information storage unit 855, the conference call identification number management means 800 displays a message that does not allow participation in the conference call.
Output to the other party's telephone via the IP network communication processing means 5000. This message is also a message that can be heard by the caller of the destination telephone.

Next, a method for confirming that it is possible to participate in the conference call by using the telephone identification number will be described. The identification number of the telephone that can participate in the conference call is stored in advance in the permission information storage unit 855 of the telephone device adapter connected to the telephone of the host who organized the conference call. Upon receiving a call request from the IP network 14, the IP network communication processing means 5000 of the calling 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 destination telephone. Next, the IP network communication processing means 5
000 receives the telephone identification number from the other party's telephone,
The received telephone identification number is the telephone identification number management means 90.
Notify 0. The telephone identification number management means 900 refers to the permission information storage unit 855 and confirms whether the notified telephone identification number is set. If set, the IP network communication processing unit 5000 outputs a message permitting participation in the conference call. This message is a message that can be heard by the caller of the other party's telephone. When 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 notifying the participation in the conference call. This message is also a message that can be heard by the caller of the destination telephone. In addition, when the host who hosts the conference call hosts multiple conference calls, the telephones that participate in each conference call are often different. In this case, the identification for identifying the conference call described above is used. A telephone identification number is set for each number. For example, when three conferences are hosted as shown in FIG. 15, the conference identification numbers are “1000” and “133” for each conference.
0'and '1600' are set, and the telephone conference identification number '1000' is assigned to the telephone conference identification number '1000' for each telephone conference identification number '500, 501, 503'. Phone identification number '50
0,600,700 ', and conference call identification number' 1
For 600 ', telephone identification numbers' 101, 102,
The setting is made as 105, 501, 502 '. The input of the telephone identification number was explained as being input from the telephone by the calling party.However, the telephone identification number is stored in advance in the telephone device adapter connected to the telephone, and the The telephone identification management unit 900 of the telephone device adapter connected to the telephone may notify the telephone device adapter of the organizer of the conference call.

Next, a method for confirming participation in a telephone conference by inputting a password will be described. It is assumed that the password is also stored in the permission information storage unit 855 included in the calling device adapter of the organizer who hosts the conference call, but the password is meaningless if it is known to anyone other than the caller. It is necessary for the caller to set his / her password for the conference call identification number in advance. The setting method will be described in another embodiment. Here, it is assumed that the password is already stored in the permission information storage unit 855 of the telephone device adapter of the conference call 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 conference call organizer sends the call request to the IP network 1
When it is received from 4, the telephone conference participant password management means 1000 is notified that there is a call request. The telephone conference participant password management unit 1000 outputs a message prompting the user to input a password to the telephone of the other party from the IP network communication processing unit 5000. This message is a message that can be heard by the caller of the destination telephone. The password is entered by the caller of the other party's telephone, and the IP network communication processing means 5
000 receives the password, and notifies the received password to the conference call participant password management means 1000.
The conference call participant password management unit 1000 refers to the permission information storage unit 855 to confirm whether the password is the set password. Since the password is set in the permission information storage unit 855 based on the telephone conference identification number, it is assumed that the telephone conference identification number is prompted at the same time when the password is prompted. Then, the IP network communication processing means 5000 receives the password input from the telephone of the other party and the telephone conference identification number. If the notified password and the conference call identification number are set in the permission information storage unit 855, the conference call participant password management unit 1000 notifies the other party's telephone of a message permitting participation in the conference call. If not set, a message notifying the participation in the conference call is notified to the other party's telephone. This notification is also a message that can be heard by the caller of the destination telephone.

It is also possible to confirm participation in the telephone conference by arbitrarily combining the respective permission information of the telephone conference identification number, telephone identification number, and password.

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

Further, since the identification number is set in the telephone conference and the identification number is directly designated and transmitted, it is possible to hold the telephone conference between the specific participants via the IP network.

Further, since the identification number is set in the telephone to which the telephone device adapter is connected and the identification number of the telephone is transmitted from the telephones participating in the conference call to the telephones of the organizer who is hosting the conference, A conference call can be held between specific telephones via an IP network.

The password assigned to each participant is managed for each conference call, and each participant is allowed to enter the password at the time of participation so that the registered password is compared and collated. Participants can be authenticated.

In this embodiment, a voice data mixing means for making a voice call from another telephone set to which the telephone device adapter is connected via the IP network and mixing two or more voice data other than the voice of the user to output the voice. The Internet telephone network system has been described which is characterized by including 700 so that a telephone conference can be held by three or more persons using a telephone.

Further, by providing the conference call identification number management means 800 for managing the set conference call identification number and the telephone identification number management means 900 for managing the telephone identification numbers of the participants of the conference call, An Internet telephone network system has been described which is characterized by the ability to authenticate conference participants.

Further, by providing the conference call participant password management means 1000 for storing and managing the password registered by the conference call participants, it is possible to authenticate the participants of the conference call. Described the telephone network system.

Fourth Embodiment 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 that stores information for controlling the communication device adapter included in the telephone device adapter. An example in which the information for changing the setting information is input and the information in the setting information storage unit is changed will be described. FIG. 16 is a block diagram of each means showing the telephone device adapter of the fourth embodiment. In FIG. 16, reference numeral 1200 denotes an IP for inputting change information for changing information for controlling the communication device adapter from the IP network 14 and accessing a storage unit in which the control information is stored to change the control information. An IP network data read / write means 1300, which is a network data read / write unit, inputs change information for changing control information for controlling the communication device adapter 12 from the telephone 10, and stores the storage unit in which the control information is stored. It is a telephone input data write means which is a telephone input data write 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, assume that maintenance work on the telephone device adapter occurs. For maintenance work, change information for changing the control information is input from the telephone 10 with a push button or the like, and the change information becomes a tone signal and is received by the public line signal transmitting / receiving means 1100. The public line signal transmitting / receiving means 1100 transfers the received change information to the telephone input data writing means 1300. Telephone input data write 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.

The change information may be input from the 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 telephone device adapter 12 can be changed from a remote place.

Also, for example, assume that a personal computer is connected to the IP network 14. From the personal computer connected to the network 14, the IP address of the telephone device adapter is specified, and change information for changing the control information is input to the telephone device adapter 12 via the IP network 14. The change information is the IP network communication processing means 50.
00, and IP network communication processing means 5
000 passes the received change information to the IP network data read / write means 1200. The IP network data read / write unit 1200 changes the control information stored in the setting information storage unit 1400 according to the change information for changing the control information passed from the IP network communication processing unit 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 device adapter, and the setting information storage section is stored according to the input change information. Since the stored control information is changed, the cost of adding the data input / output device dedicated to the maintenance work to the telephone device adapter can be reduced. A user or the like can easily perform maintenance setting work with a conventional device.

FIG. 12 described in the third embodiment.
The permission information such as the conference call identification number, the telephone identification number, and the password stored in the permission information storage unit 855 illustrated in FIG. 2 is input to 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 write means 1300 when the input is performed from a remote telephone. When inputting from the personal computer via the IP network 14, the IP network data read / write unit 1200 may access and register the permission information storage unit 855. Since it is possible to register permission information related to conference calls by inputting it from a telephone connected to the telephone device adapter or a personal computer connected to the IP network, it is thought that new registration or change or deletion of registered information will occur frequently. It is possible to easily perform the registration change work of the permission information regarding the telephone conference to be performed.

An internet telephone network system has been described which is characterized in that it can be performed from a telephone to which a telephone device adapter is connected.

Embodiment 5. 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, but in the fifth embodiment, the IP network communication is performed. The detailed internal configuration of the processing means 5000 will be described. FIG. 17 is a network configuration diagram including a firewall on the IP network according to the fifth embodiment. In FIG. 17, 17, 2
7 is a firewall. Other symbols are shown in FIG.
The description is omitted because it is similar to. 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 of FIG. 15 can be applied as it is to the IP network communication processing means 5000 of the drawings described in the first to fourth embodiments.

In FIG. 18, reference numeral 5100 denotes a User Datagram Protocol as a communication protocol for transmitting and receiving voice data on the IP network 14.
U capable of performing processing (hereinafter, referred to as UDP)
A UDP communication processing unit 5200, which is a DP communication processing unit, is a UDP port use management unit, which is a UDP port use management unit that transmits and receives voice data to and from a firewall via a specific UDP port, and 5300 is a firewall. UDP port communication confirmation means, which is a UDP port communication confirmation unit for investigating the existence of a UDP port capable of transmitting / receiving data, 5400 is Real as a communication protocol for transmitting / receiving voice data on an IP network.
-RTP capable of performing a time transport protocol (hereinafter referred to as RTP)
It is an RTP communication processing means that is a communication processing unit.

Next, the operation will be described with reference to the flowcharts of FIGS. 19 and 20.
Is the same processing as in FIGS. 10 and 11 described in the second embodiment. FIG. 21 shows the processing for the fifth embodiment. The IP network communication processing means 5000 operates in the transmission / reception processing of the voice data in the call state in the first to fourth embodiments. A case will be described in which voice data is transmitted from the calling device adapter 22 of the other party who is talking to the calling device adapter 12 via the IP network 14, but before that, using the communication protocols of UDP and RTP. A header for transmitting / 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, the IP header 51 and the UDP header 5 are applied to the voice data 50.
2 and RTP header 53 are added to form an IP packet. When the voice device adapter 12 receives the voice data from the voice device adapter 22 via the IP network 14, the UDP communication processing means 5100 transmits the voice data I
UDP header 5 without IP header 51 from P packet
Take out the packet with 2. Next, the RTP communication processing means 5400 extracts the packet with the RTP header 53 from the packet with the UDP header 52, and further,
The digital voice data body from which the RTP header is removed is sent to the voice data digital-analog conversion means 500, converted into analog voice data by the voice data digital-analog conversion means 500, and the public line signal transmission / reception means 11
00 to the telephone set 10. Although it has been described that the analog voice data converted by the voice data digital-analog conversion means 500 is sent to the telephone set 10 via the public line signal transmission / reception means 1100, the voice data digital-analog conversion means 500 directly transfers the IP network communication processing means 5000. Public line signal transmission / reception means 1 via
The route may be such that analog voice data is sent to 100 and output to the telephone 10.

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

By using UDP, when a packet of voice data does not arrive at the telephone device adapter 22 connected to the telephone 20 of the other party, the retransmission process is not performed. Therefore, it is possible to improve the real-time characteristics of voice data communication. Further, by using RTP, it is possible to manage the transmission time and count of packets of voice data, so that it is possible to improve the real-time characteristics of voice data communication.

Next, in order to deal with the case where the IP network route is blocked by the firewalls 17 and 27, a configuration for confirming whether or not the UDP port can be used will be described. It is assumed that the information indicating that the network environment of the other party is blocked by the firefall 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 other party's network environment when making a call.

The procedure for making a call from the telephone set to which the telephone device adapter is connected and the processing procedure when a call is made are the same as those in FIG. 10 and FIG. 11 described in the second embodiment, but the other party is connected via the IP network. When it is determined that the call can be made to the telephone, the processing for confirming the existence of a port capable of communicating with the communication device adapter of the other party of the call is performed. Figure 1
Telephone device 10 to telephone device adapter 12 on 9, 20, and 21
6 shows a flowchart of a procedure for making a call via the Internet. Figure 1
9 is the same processing as that of FIG. 10 described in the second embodiment,
20 is the same process as that of FIG. 11 described in the second embodiment. FIG. 21 is a flowchart of the process added in the fifth embodiment. S2400 to S2406 of FIG. 21 are shown in FIG.
This is a process corresponding to the process of S24 of 0. In FIG. 19, when the corresponding IP address can be acquired based on the telephone number input from the telephone 10 (S23), UDP
The port communication confirmation means 5300 scans each port of the communication device adapter of the other party via the IP network 14 and checks whether or not access is possible through an arbitrary UDP port (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 from the telephone device adapter connected to the telephone of the other party within a certain time, it can be known that the port number can be used. When access is possible with an arbitrary UDP port, the port number of the UDP port checked by the UDP port communication confirmation means 5300 is set in the destination port number of the UDP header 52, and the voice data communication process is performed with the arbitrary UDP port. Is started (S2401). If not possible,
It is confirmed whether communication is possible with respect to the previously specified UDP port managed and stored by the UDP port use management means 5200 (S2402). Generally, the firewall does not allow the specification of an arbitrary UDP port, but it is possible to set the firewall so that a limited specific UDP port can be used. In that case, the limited specific UDP port is managed and stored in advance in the UDP port use management means 5200. If this is possible, the voice data communication process is started at the specified UDP port (S2403). If this is not possible, it is possible to search for another communication port 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 the HTTP port can be accessed as in S2404, the HTTP port communication confirmation means described in the sixth embodiment is required. Here, if it is determined "No" in the process of S2402, it is confirmed whether access through the HTTP port is possible. If "No" in the process of S2402, the error notification process of S2406 is performed. You may branch to.

As described above, since UDP and RTP, which are excellent in the real-time characteristics of communication processing, are used, the voice quality of a call can be improved. Also,
Generally, for a firewall that does not allow the use of any UDP port, configure the firewall so that a very limited number of specific UDP ports can be used, and set that specific UDP port number in the intercom adapter. By storing the data, it is possible to perform communication processing of voice data that exceeds the firewall. Furthermore, 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 an available UDP port is unknown, it is searched for and voice data communication is performed. Processing can be performed.

The Internet telephone network system, which is provided with 800 and is capable of transmitting and receiving voice data by HTTP, has been described.

Further, when the telephone device adapter makes a call via the IP network, security for prohibiting 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. For the purpose of the firewall, the HTTP port communication confirmation means 5900, which investigates the existence of an HTTP port capable of transmitting / receiving data, identifies the HTTP port capable of transmitting / receiving voice data, and uses the HTTP port. The Internet telephone network system characterized by being able to make voice data calls has been described.

Seventh Embodiment In the drawings of the above-described first to sixth embodiments, the configuration diagram of each means showing the communication device adapter of the internet telephone network system of the present invention is shown, but in the seventh embodiment, detailed description of the IP network communication processing means 5000 24 and 25 are internal configuration diagrams.
Shown in. This IP network communication processing means 5000 can be applied as it is to the same means in the drawings of the first to sixth embodiments. It is assumed that the network system configuration diagram of 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 is a voice data packet encoding unit for compressing voice data itself and changing the header of a packet in a standard format such as RTP or HTTP into a compressed header in which the minimum necessary information is limited. Audio data packet encoding means, 5600
Is a voice data packet decoding unit that is a voice data packet decoding unit that decompresses the received voice data itself and analyzes the compressed header to obtain a header of a packet in a standard format such as RTP or HTTP. The buffer size is set so that the digital audio data packet received from the destination telephone 20 connected to the IP network at a discontinuous timing due to changes in network traffic is converted into an analog signal and sent out with a constant delay. A reception buffering unit, which is a reception buffering unit for temporarily storing in a changeable reception buffer, 6200
Creates a digital voice data packet to be transmitted when transmitting the digital voice data packet to the destination telephone 20 connected to the IP networks 14 and 24,
A buffer size can be changed. A transmission buffering unit, which is a transmission buffering unit for performing processing of adding only necessary data to a packet assembly before accumulating in a transmission buffer and transmitting, 6300 is connected to IP networks 14 and 24. When transmitting a digital voice data packet to the telephone set 20, a redundant packet issuing unit for transmitting the same voice data packet in a variable number in a duplicated manner in order to cope with a voice data packet loss that occurs depending on the state of network traffic. The redundant packet issuing means, 6400, is for transmitting digital voice data packets to the telephones connected to the IP networks 14 and 24 in order to reduce network traffic.
Packet generation filtering means, which is a packet generation filtering unit capable of reducing the number of voice data packets to be transmitted, 6500 is the IP network 1
4 is a network traffic monitoring means which is a network traffic monitoring unit for monitoring the reception timing of voice data packets from 4, and 6600 stores statistical data of the network traffic status, and averages in each time zone in a cycle such as one day or one week. It is a network traffic statistical data management unit that is a network traffic statistical data management unit that calculates a parameter indicating a typical traffic condition.

Next, the operation will be described. As in the first to sixth embodiments, the IP network communication processing unit 5000 is used in the voice data transmission / reception process during the call state.
Works. This IP network communication processing means 500
The basic operation of 0 is performed similarly to the fifth to sixth embodiments. Here, the RTP communication processing means 5400 and HTTP
When sending and receiving audio data to and from the communication processing means 5800, the audio data packet encoding means 5500 allows the audio data and RTP and 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 the case where a remodeled header in which only the necessary minimum information is compactly compiled is not actually conformed to the header format defined by the standard.

Since various data traffics exist on the IP network, the voice data packets do not always arrive at regular intervals. Such variations in the arrival time of each packet is called fluctuation of transmission time. When a packet is received in order to absorb the fluctuation of the transmission time, the packet of the voice data is stored in the reception buffer and is output to the public line signal transmitting / receiving means 1100 on the analog side at regular intervals. In this way, even if a delay occurs in each packet, the timing at which the audio data goes out to the output side is constant and the reproduced sound is not interrupted as long as it is within the capacity of the receiving buffer. This processing is performed by the reception buffering means 6100. Reception buffering means 610
Reference numeral 0 is a unit that has a reception buffer 6101 and performs the above processing. Since the delay in reproducing the voice increases 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 a trade-off between delay and fluctuation from the actual call quality (if there is fluctuation in the arrival time of voice data packets transferred via the IP network, for example, when explaining an extreme example, "Good morning. The conversation "..." sounds like a blank time "..." is inserted, such as "O ... hayogo ... zaima ... su ...". There is a break in the sound.) So, in order to fill the blank time of "...", prepare a receive buffer,
By delaying the entire playback time, the processing of the reception buffer is to remove the interruption of the sound. The larger the size of the receiving buffer, the more the interruptions will disappear and the voice quality will improve, but the overall delay will increase, so that the speaking timing will be delayed and difficult to hear. That is,
When the receive buffer size is increased, fluctuations are absorbed and the voice quality is improved, but on the other hand, delay increases and it becomes difficult to hear, and when it is decreased, the voice quality is deteriorated.
It becomes easier to adjust the timing of speaking. The reception buffer size is determined by the trade-off between the characteristics of both. ), It is necessary to set the optimum value. However, in reality, the optimum value fluctuates depending on the situation of network traffic. Reception buffering means 6100
Then, the capacity size of the reception buffer 6101 can be changed according to an arbitrary condition. In addition, in order to deal with the case where the buffer overflows frequently, the capacity size of the buffer is set to a large value so that only a part of the data sent out from the audio data digital-analog converting means 500 on the reproducing side is always sent. There is also. In this case, it is conceivable that not only the capacity size of the reception buffer but also the size of the data sent to the audio data digital-analog conversion means 500 on the reproducing side is controlled to be changed according to various conditions.

Similarly, in order to deal with various data traffic conditions on the IP network, it is conceivable that the transmitting side may change the size of the voice data packet to be sent to the IP network 14. For this purpose, the transmission buffering means 6200 has a transmission buffer 6201. Transmission buffering means 620
0 stores a certain amount of audio data in the transmission buffer 6201 and then transmits it. The smaller the packet size of the voice data to be transmitted, the smaller the delay and the better the call quality.However, since each packet always has a header part of a certain size, the size cannot be reduced even if the packet size is reduced. There is a limit. If the size is further reduced, the amount of packets will increase and the amount of network traffic will increase. Therefore, the size of the transmission buffer is also changed according to the network traffic situation.

Similarly, in order to deal with various data traffic conditions on the IP network, a packet of voice data of exactly the same content is prepared in case a packet loss of transfer data frequently occurs in the UDP communication processing. As a backup, it is possible to take a measure to duplicate and transmit.
The redundant packet issuing means 6300 performs this processing. This redundant packet is not always issued, but if network traffic increases, the delay of the entire packet increases, so in order to reduce unnecessary packets,
It is necessary to adjust so that redundant packets are not issued either.
Network traffic hasn't increased much,
When the packet loss frequently occurs, the redundant packet is controlled so that the packet loss is reduced and the communication quality is improved.

Similarly, in order to deal 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 call quality is not affected. A control that does not transmit a packet of voice data can be considered. This processing is performed by the packet generation filtering means 6
It is 400. Here, as a condition for performing filtering, it is conceivable that the sound data volume level is set to a value other than a certain level. This is because it has already been confirmed by human hearing that the sound having a certain volume level does not affect the call even if it is not reproduced. As a result, as the network traffic increases, the limit level of the volume of voice data to be removed at the time of transmission is controlled to increase so that the amount of voice data to be removed can be controlled to continue the call with almost no loss in call quality. it can.

Similarly, in order to deal with the data traffic situation on the IP network, various communication controls are performed by each means in the communication processing.
Therefore, in order to grasp the network traffic condition, the reception timing of the packet of the voice data is continuously recorded by the network traffic monitoring means 6500. Thereby, the amount of network traffic is estimated and the conditions for the above communication control are changed appropriately. For example, in the case of the reception buffering means 6100, when the network traffic monitoring means 6500 confirms that the network traffic has increased, it notifies the reception buffering means 6100 to increase the capacity size of the reception buffer 6101. If the capacity size of the receive buffer is increased, the receive buffer 6
Since packets are accumulated in 101 and then passed to the voice data digital-analog conversion means 500, network traffic can be eliminated. On the contrary, when the network traffic decreases, the packet arrives at the communication device adapter at a stable timing.
The reception buffering means 6100 is notified so as to reduce the capacity size of the reception buffer 6101.

Further, in order to deal with various data traffic conditions on the IP network, statistical data is utilized for changing the various parameters for the above communication control. Network traffic monitoring means 6500
In order for the network traffic statistical data management means 6600 to receive the data monitored and accumulated by the above, and to perform the communication control by the reception buffering means 6100, the transmission buffering means 6200, the redundant packet issuing means 6300, and the packet generation filtering means 6400 described above. Provide the necessary information. The network traffic statistical data management means 6600 shows the average network traffic tendency in a cycle of one day or one week.
Can be used as a reference for performing communication control by each means.

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

As described above, the header of the packet of the voice data to be communicated is uniquely compressed. Therefore, the packet size can be made smaller than the standard packet size, and network traffic can be reduced. This unique compression is, for example, compression of the information in the header section using a compression program to reduce the size, or compression in which only the data necessary for the communication device adapter, which is an element of the present invention, is included in the header section. Refers to doing.

Further, even if there is fluctuation in the transmission time of each packet of the voice data to be communicated, the packet is stored until it reaches a certain size at the time of reception and is sent to the analog reproducing side. Even if it is stable, stable call quality can be maintained.

Further, at the time of transmitting each packet of voice data to be communicated, the packet size is reduced when the amount of network traffic is small, and 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 redundant packets can be issued when packet loss frequently occurs during transmission of each packet of voice data to be communicated, even in a situation where network traffic frequently causes packet loss, Can maintain stable call quality.

Further, when the packet of voice data to be communicated is transmitted, when the network traffic amount increases, the packet of voice data which does not affect the call quality under a condition such as a certain volume level or less is not transferred. Therefore, stable call quality can be maintained even if the amount of network traffic increases.

Further, the reception timing of each packet of voice data to be communicated is measured, the network traffic situation is estimated, and various parameters of the above communication processing are adjusted, so that the latest situation of network traffic can be obtained. Depending on the optimum communication processing,
Can maintain stable call quality.

Further, 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 the data indicating the network traffic condition in a cycle such as one day or one week. It is possible to control the optimum communication processing corresponding to various network traffic situations, and maintain stable call quality.

Also, it is provided with a voice data packet decoding means 5600 for decompressing the received compressed voice data itself and analyzing the compressed header to obtain a header of a packet of a standard format such as RTP or HTTP, thereby reducing the amount of transmitted / received data. The feature is that it is possible to perform efficient transmission / reception processing of call data. It described the Netto telephone network system.

[0187] Further, for a telephone connected to the telephone device adapter, a digital voice data packet received at a discontinuous timing due to a change in network traffic from the telephone of the other party via the IP network is converted into an analog signal. It is characterized in that it is equipped with a reception buffering means 6100 for temporarily storing in a reception buffer whose buffer size can be changed so that the transmission timing is fixed delay, and an analog voice signal can be transmitted to a telephone at a stable timing. The Internet telephone network system to be described.

The transmission mode of the digital voice data packet is optimized according to the network traffic condition. The Internet telephone network system has been described which is characterized by being capable of transmitting voice data of high quality.

In addition, when a digital voice data packet is transmitted to a telephone set connected to the telephone equipment adapter to a destination telephone set via the IP network, packet loss of voice data may occur depending on the state of network traffic. In order to cope with the above, the redundant packet issuing means 6300 for transmitting the same number of voice data packets by overlapping in a variable number is provided, and good quality voice data can be transmitted even if the network traffic situation deteriorates and packet loss occurs. The Internet telephone network system characterized by.

In addition, when a digital voice data packet is transmitted to a telephone set connected to the telephone equipment adapter to a telephone set of the other party via the IP network, the transmission target is set in order to reduce network traffic as much as possible.

The Internet telephone network system characterized by being able to transmit high-quality voice data 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 detects any specific data. After detecting the situation, an instruction is issued to change the operating status of the various units of the reception buffering means 6100, the transmission buffering means 6200, the redundant packet issuing means 6300, and the packet generation filtering means 6400 provided in the telephone device adapter. The Internet telephone network system has been described, which is characterized in that it can realize optimum transmission / reception processing according to network traffic conditions and can transmit high-quality voice data.

Further, the network traffic monitoring means 6500 for monitoring the reception timing of the voice data packet received via the IP network is received and stored in the telephone connected to the telephone device adapter. One day or one
Using the network traffic statistical data management means 6600 that calculates a parameter indicating an average traffic condition in each time period in a cycle such as a week, the reception buffering means 6100 and the transmission buffering means provided in the communication device adapter are used. 6200, redundant packet issuing means 6300, and packet generation filtering means 6400 can be instructed to change the operation status, optimal transmission / reception processing can be realized according to average network traffic status, and high-quality voice data can be transmitted. The Internet telephone network system characterized by.

What is HTTP access? HT
By assuming that the TP relay server is a web server and the telephone device adapter has a web browser, each telephone device adapter sends voice data to the HTTP relay server which is regarded as a web server by a POST message in HTTP. You can
Further, each telephone device adapter can acquire the location where the voice data output from the telephone set to which each telephone device adapter is connected is stored by the GET message. This is called HTTP access. The call processing can be realized by temporarily holding the voice data in the HTTP relay server, and the call device adapter connected to another telephone that needs the voice data acquires the voice data. Reference numeral 8200 is telephone call information for confirming whether or not a call device adapter is being called by each call device according to a call from the call device adapter, and for replying when there is an inquiry from each call device adapter. A telephone call information management unit, which is a management unit, 8300 is two communication device adapters, for example, a telephone 10 and a telephone 2.
When a conversation is made with 0, the HTTP relay server 18 is connected to the telephone device adapter 12 connected to the telephone 10 and the telephone device adapter 22 connected to the telephone 20 to connect the HTTP relay server to the web server and the telephone device adapter to the web browser.

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

In FIG. 28, 7300 is an HTTP telephone calling means which is an HTTP telephone calling unit for transmitting telephone calling information to the HTTP relay server 18 by HTTP access, and 7100 is a telephone calling information management means 8200.
HTTP polling means, which is an HTTP polling unit for checking the call status of the call device adapter of the call destination stored in the table by polling for HTTP access using inquiry information, and 7200 is the call device of the call destination by the telephone number IP address conversion means 300. When the adapter is found to be blocked by a firewall, it is a telephone call communication unit that is a telephone call communication unit that reports that a telephone call device adapter of a call destination is being called.

29 and 30 are a first example and a second example of the configuration diagram of each means showing the HTTP relay server management server of the Internet telephone network system of the eighth embodiment. 29 and 30, 9200 indicates a plurality of HTTs.
HTTP relay server load state monitoring means, which is an HTTP relay server load state monitoring unit for monitoring the load state of the P relay server, and 9100 is an HTTP relay for designating the HTTP relay server used in the call process in response to an inquiry from the telephone 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 that prepares a plurality of HTTP relay servers 18 themselves of FIG. 27 and collectively manages them. In the second example of FIG. 30, only the processing means necessary for connection negotiation with the telephone device adapter is extracted from the HTTP relay server 18 of FIG. The form in which the relay server management server 180 performs the process of connection negotiation is shown. 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 that means.

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

The procedure for making a call from one communication device adapter to the other communication device adapter is as follows. Number IP address conversion means 3
00 is converted into the IP address of the other party. I
An example of converting to the P address is the same as that described in the first embodiment.

(In case of polling method) S22 of FIG.
Convert the phone number into an IP address with
If the IP address can be converted into the P address, the HTTP telephone calling unit 7300 next flags the management area for each IP address of the telephone call information management unit 8200 in the HTTP relay server 18 for the IP address that is about to be called. Information is set (S62). The management area for each IP address of the telephone call information management means 8200 is always
Since the HTTP polling means 7100 of the telephone conversation device adapter of the other party of the call regularly refers to its own management area in the telephone call information management means 8200 in the HTTP relay server, it is connected to the destination telephone. The intercom adapter can know that a call is being made.

(In the case of mail or instant message) When the IP address can be converted from the telephone number in the confirmation processing in S23 of FIG. To the other party's telephone to inform that the other party's telephone is being called. The processing in the case of mail or instant message is not particularly shown in the flowcharts of FIGS. 32 and 33.

(When making a call by calling from the public line) When the telephone number can be normally converted into the IP address in S23 of FIG. 33, next, the public line signal transmitting / receiving means 110
When 0 is called from the public line side to the telephone of the other party, the telephone device adapter connected to the telephone of the other party instantly informs that the telephone is being called.

Then, the communication device adapter of the other party also sends a ring tone to the telephone set to which the communication device adapter is connected in order to start a call. If the handset of the other party's phone to be called is picked up, it becomes a call state, and while each other's telephone device adapter goes to the other party's call data,
If necessary, the call data that one speaks is transmitted to the HTTP relay server. This continues until disconnected. A voice data buffer is a portion where call data is sent from this telephone device adapter and is 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 telephone call. To do. 32, S66 and S
The processing of 67 and S68 is a procedure until a call is made and a call is continued when a call is being made from another person, and S62, S63, S64, and S65 of FIG. This is a process of a procedure that continues until the receiver of the other party's telephone is picked up and the call becomes in the call state and the call is disconnected. The two telephones make a call via the HTTP relay server in the same way when making a call and when making a call. Therefore, after the telephone call state described above, the two telephones make a mutual call to the HTTP relay server. The process of transmitting / receiving the call data via S66 to S68 in FIG.
33 corresponds to the description of the processing of S62 to S65 in FIG.

Next, the flowchart (polling method) of the HTTP relay server of FIG. 34 will be described. The HTTP relay server 18 accepts only HTTP access from the outside via the IP network. FIG. 34
Then, the HTTP communication processing means 5800 confirms whether the HTTP access data is received in S70. Only in the polling method, there is HTTP access for confirming whether or not a call is made from each communication device adapter to itself. Other than that, there is access for making a new call to another phone, access for sending voice data and acquiring voice data for yourself, and HTTP access for contact when disconnecting a call. To do. When it is determined in S71 that HTTP access is to make a new call to another phone, the telephone call information management means 8200 accesses the management area of the other party of the call to determine whether the call is already in progress or not. Check (S75). If the call is in progress, the HTTP message in the call is returned (S7).
6, S77), otherwise, the fact that the telephone call has started is returned as an HTTP message (S78). In the case of a call state, the voice data buffering means 8100 manages so that the voice data delivered from the telephone device adapter is temporarily stored (S79) and is 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 treated as an HTTP return message by the voice data buffering means 8100 and the HTTP communication processing means 5800.
Then, the transmission is performed to the telephone device adapter connected to the telephone set of the called party (S80). In the process of S71,
In the case of HTTP access for confirming whether or not a telephone call is made to the telephone device adapter itself, the telephone call information management means 8200 manages whether or not the telephone connected to the telephone call device which is the source of the confirmation request is telephone-calling. The information is checked (S72). As a result of the examination, if there is a telephone call (S73), the 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 confirmation requesting telephone (S74). Further, when it is determined that the HTTP access for disconnecting the call is performed in the process of S71, the telephone call information management means 8200 changes the information indicating that both the management information of the call source and the call destination are waiting. Yes (S81).

As described above, since a general firewall can access the external Internet by HTTP, the communication device adapter enables the telephone call and the call processing via the HTTP relay server. It is possible to make a phone call via the IP network without having to make any setting changes to the firewall.

In the HTTP relay server, the call data is transmitted and received after the processing of the first connection negotiation with each communication device adapter. However, since the processing load is considerably heavy, the call data is transmitted and received by the HTTP relay server. If the processing is performed directly between both communication device adapters without going through the server, the processing load of the HTTP relay server will be reduced,
Even if many users make calls and the call processing is concentrated, the processing can be continued without delay and the call quality can be maintained. For this reason, the HTTP connection changing means 8300 changes the HTTP and TCP connections directly to the connection between both adapters after the first connection negotiation.

As described above, the transmission / reception of the call data is H
Since the processing load of the HTTP relay server is reduced because the processing is performed directly between both communication device adapters without going through the TTP relay server, many users make calls and call processing concentrates. Also, the processing can be continued without delay and the call quality can be maintained.

[0208] Further, the HTTP relay server transmits and receives the call data after the processing of the first connection negotiation with the telephone device adapter, but since the processing load is considerably heavy, the processing performed by the HTTP relay server is performed. It is possible to perform only the simplest processing possible. this is,
The IP address of the IP header part in the packet of the voice data transferred from the two telephone device adapters to the HTTP relay server when both the telephone device adapters for making a telephone call are connected by the HTTP relay server and the call processing is prepared.

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

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

Thirteenth Embodiment As described in the second embodiment, the calling device adapter learns the IP address of the other party of the call both when the call is made and when the call is made. However, when a call is made, it is sufficiently assumed that the same party will be called, but if the call is made, the possibility of making a call to the person is not necessarily high. For example, when making a call for the purpose of selling sales or for inquiring for specific information, there is almost no case where the called party makes a call. Therefore, when a call is often made for such a purpose, the I
An address conversion table 30 for storing the P address
It is fully assumed that 2 entries will be consumed.

From the above, in the communication device adapter of the user who can often make a 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.

[0233] When a telephone call is made as described above, the IP
It is possible to adopt the specification of processing that does not learn addresses, but since such a situation is expected to change, the user can change the setting whether to use such processing specifications. By doing so, the convenience for the user can be improved. Therefore, it is possible to select whether or not to learn the IP address of the other party of the call when a call is made, as the setting of the communication device adapter using the maintenance function described above. Alternatively, when the user makes a call, the address learning prohibition information instructing not to learn the IP address is continuously input after the telephone number of the destination by using the dial of the telephone or the push button. Alternatively, enter it in front of the other party's telephone number. The address learning prohibition information is set in advance in a predetermined dial or a predetermined push button. The public line signal transmitting / receiving means 1100 detects this address learning prohibition information and notifies the IP address learning means 400 that the IP address learning is not performed. In this way
It does not matter if the IP address of the other party of the call is not learned.

In the second embodiment, the public line signal processing unit is called by the learning process of the IP address learning unit that learns the address information of the calling device from the calling side and the called side. Although an example of the Internet telephone network system characterized in that both the calling side and the calling side are carried out has been described, in the thirteenth embodiment, the public line signal processing unit makes a call from the calling side. The example of the Internet telephone network system is described in which the learning process of the IP address learning unit that learns 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 that learns the address information of the calling device from the calling side and the called side with the calling side. A mode that is performed by both the caller side,
The IP address learning unit that learns the address information of the calling device from the calling side can be set in mode by allowing selection of two modes that the calling side does not perform. It is also possible to build a simple internet telephone network system.

Fourteenth Embodiment In the fourteenth embodiment, a mechanism for exchanging IP addresses with each other after the call described in the second embodiment is completed will be described in more detail. FIG. 38 shows that in both users,
1 shows a schematic configuration when a telephone call is made using a telephone device (telephone) and the telephone device adapter. Telephone circuit I / F (interface) control circuit 11 in the adapter of FIG.
Reference numeral 10 is a collective term for the public line signal transmitting / receiving means 1100, the line connection switching means 100, the connection destination determining means 200, and the like.

After the end of the call, the user places the handset of the communication device on the communication device body after an appropriate time has elapsed.
The state of this handset is generally called on-hook. On the contrary, the state where the handset is picked up is called off-hook. If the on-hook state of the handset is directly transmitted to the exchange of the public line, the line of the call is disconnected, so that the IP address information cannot be exchanged. 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 telephone device adapter is directly connected to the public line instead of the telephone device.

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

This is because the public line signal processing unit
Immediately after both users who are talking have finished the call and on-hooked the handset, the call information was sent to the other party who sent the call information while maintaining the connection on the public line without disconnecting. An example of an internet telephone network system is described in which address information corresponding to the identification information of the above-mentioned communication device on the side of transmitting the is transmitted via a public line.

[0240] Fig. 39 shows an example of a sequence of procedures for transmitting / receiving IP address information. Here, the sequence when the telephone A is called from the telephone A is shown by (1) to (9). The called telephone B sends a disconnection tone as a signal to start the first processing (1). At the time of transmitting the disconnection tone of this first signal, it is necessary that the user has already hooked the handset on both of the communication devices. Therefore, when the call ends, the user waits for a sufficiently long time, for example, about 5 seconds, before placing the handset, and then the first disconnection tone is transmitted. By doing so, the IP address transmission / reception process succeeds in most cases. If the disconnection tone is transmitted while the telephone set A is still in the off-hook state, the call fails and the IP address transmission / reception process is executed again after the next call.

[0241] This means that it is predicted that the public line signal processing unit predicts that the other user will be on-hook immediately after the other user who is talking has finished the call and hooked the handset on the other hand. Address information corresponding to the identification information of the communication device on the side transmitting the call information to the other party who transmits the call information while maintaining the connection on the public line after the lapse of time An example of an internet telephone network system characterized by transmitting a message via a public line is described.

Further, after the end of the call, in order to delay the on-hook operation of the handset to the start of the IP address transmission / reception processing, when one of the communication devices is on-hook, the communication device adapter connected to the communication device is connected to the communication device of the communication partner. On the other hand, by transmitting a busy tone (a tone indicating that the phone is busy), the on-hook operation of the handset can be prompted. This is because, in general, when the user is busy tones, it is more habitual to put the handset on immediately than when there is no sound. In addition, it may be more effective to transmit a tone with a stronger warning color tone than a busy tone.

This is because the public line signal processing unit causes the other user to put the receiver on hook immediately after the one user who is talking ends the call and hooks the receiver on the other hand. An example of an Internet telephone network system is described in which the above-mentioned telephone device adapter of the user transmits a tone, such as a busy tone, to the user to inform the user of the end of the telephone call.

Furthermore, during the IP address transmission / reception process, or even if the use of the telephone is immediately resumed, the use is impossible. As the processing of the communication device adapter, after the IP address transmission / reception process is started, the connection of the public line to the communication device side is not switched until the process is completely completed. In order to notify the user of such a state, a sound such as a busy tone can be heard to warn the user that the call cannot be used even during the IP address transmission / reception process. When the off-hook operation of the handset of the communication device is detected during the IP address transmission / reception process, it is possible by transmitting a busy tone to the communication device side. As described above, it is also possible to emit another tone having a stronger warning color than the busy tone.

This is because the public line signal processing section holds the connection on the public line without disconnecting immediately after both users who are talking have finished the call and hooked the handset. While the address information corresponding to the identification information of the communication device on the side transmitting the call information is being transmitted to the other party who transmits the call information via the public line, one of the two users Also, when the handset is taken off-hook to use the telephone, in order to warn the user that the call cannot be made because of the transmission process, the call device adapter of the user sends the call device to the call device. , An example of an internet telephone network system characterized by transmitting a tone, such as a busy tone, that informs the user of the impossibility of a call is described.

In the above, during the IP address transmission / reception processing,
Although the operation for making a call was not possible, the telephone device adapter can accept only the telephone number input operation from the telephone device. Therefore, instead of giving a 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 P-address transmission / reception process is completed, a normal telephone call process can be executed. Since the IP address transmission / reception process does not take many minutes, there is a high possibility that the IP address transmission / reception process is sufficiently completed during the operation of inputting the telephone number of the user. By doing so, even if the user tries to make a call again immediately after the end of the call, the user can use the call without waiting in the IP address transmission / reception process.

This is because the public line signal processing unit holds the connection on the public line without disconnecting immediately after both users who are talking have ended the call and hooked the handset. While the address information corresponding to the identification information of the above-mentioned communication device on the side transmitting the above-mentioned call information is being transmitted to the other party to whom the call information is transmitted via the public line, one of both users Also, when the handset is off-hook to use the telephone, the identification information of the communication device of the user's call destination is received and stored, and after the transmission processing is completed, the call corresponding to the identification information is received. An example of an 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 mentioned, but next, for the convenience of the user, the point that the registration of the IP address of the other party of the call 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. Embodiment 1
The explanation was given in 3. Therefore, when a call was made, it was possible to set so that the IP address would not be registered uniformly, but including such cases,
If you assume that you will never make a call to the other party after you have made a particular call, you will be able to cancel the registration of the other party's IP address immediately after the call. . For example, a wrong phone call, a complaint phone call from a customer, an inquiry phone, or a questionnaire phone call. In order to realize this function, after the IP address transmission / reception processing after the call ends, the user picks up the handset and puts a number indicating the execution of the registration deletion function together with a specific # or * symbol (deletion instruction information). Make it input to the communication device. Based on this input operation, the public line signal transmitting / receiving unit 1100 in the telephone device adapter deletes the registration of the entry of the IP address table stored immediately before via the telephone number IP address converting unit 300. In this way, it becomes possible to delete the registration of the IP address of the other party of the call which is unnecessary for the convenience of the user.

This is learned by the IP address learning unit after the call when the public line signal processing unit obviously does not use the next call such as a wrong call when the user makes a call. An example of the Internet telephone network system is described in which the registration of the address information of the above-mentioned calling device of the called party can be deleted by an operation such as a button input of the calling device.

Fifteenth Embodiment In the second embodiment,
In S21 of FIG. 4, it is shown to confirm the input of the telephone number. In the fifteenth embodiment, the contents will be described in more detail. Since the telephone number, which is the identification information of the communication device, has various digits, various methods can be considered to determine whether or not the user has finished the input operation of the telephone number. Basically, the continuous operation of inputting one digit one digit of a telephone number takes an appropriate time (for example, 0.3
It is repeated every (about seconds). Since it is assumed that this time interval rarely exceeds, for example, 5 seconds, it is possible to determine that the input of the telephone number is completed if there is no input operation at the time when a certain set time is exceeded. it can. Since this set time may depend on the user's habit of telephone operation, it is desirable to set an appropriate time for each user, so that the user can change the set time.

This means that the public line signal processing unit determines whether or not the user who is making a call determines whether or not the input of the identification information of the callee of the call destination to be input to the caller has been completed. An example of the Internet telephone network system is described in which the input is performed by detecting a state in which the input is not performed even after a lapse of a specific time.

In the above, the waiting time for determining the input end is set to about 5 seconds, for example, but it is assumed that some users may not like to wait for such waiting 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 communication device adapter side of the end, the end of characters such as #, *, etc., which are appropriate ends, is notified. It is also possible to take a method of inputting information. Of course, in combination with the method of inputting the end information, it is possible to automatically determine the end after the set time has elapsed without any input. On the other hand, if it is basically fixed to a predetermined size, for example, a 4-digit telephone number, such as an internal extension, enter 9 etc. at the beginning of the entry to make it an extension number. It is also possible to automatically determine the end of the input operation by informing that, and then inputting a 4-digit telephone number.

This means that the public line signal processing unit determines whether input of the identification information of the communication device of the call destination to be input to the communication device by the user who is making the call is completed by inputting continuous information of each character. An example of an internet telephone network system is described which is characterized by detecting that a character indicating a specific final input has been input therein.

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

This means that the public line signal processing unit determines the completion of input of the identification information of the communication device of the call destination, which is input by the user making a call to the communication device, to the upper identification information ( Confirm the input of (telecommunications carrier information), determine the number of digits (size) of the identification information according to the number system of the upper identification information of each telephone company, and make the final input while counting the number of input characters An example of an Internet telephone network system characterized by detecting and performing is described.

The high-level identification information for each telephone service company will be described below. The company name of the telephone service company is abbreviated. Higher-order identification information A 3- to 4-digit number that is prefixed and dialed when using a carrier other than NTT from an NTT subscriber telephone. Two
Since the spring of 001, a "telephone priority connection system" will be introduced, in which if you normally register a telecommunications carrier to use in advance, you can omit the 3- to 4-digit identification number and make a call.
With the reorganization of T, this identification number was also given to NTT East and NTT West in August 1999 by the Ministry of Posts and Telecommunications. FIG. 40 shows high-level identification information for each telephone service company (telecommunications carrier). However, the company name of the telephone service company (telecommunications carrier) described in FIG. 40 is abbreviated.

On the other hand, after S21 of FIG. 4 of the second embodiment, reference processing of the address conversion table is performed 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 of narrowing down the IP address table entry candidates from the upper digits little by little each time the telephone number is input by one digit. Can also be taken.

This means that the connection destination judgment unit performs the conversion processing by the address conversion unit on all the identification information input to the communication device of the communication destination after the completion of the input of the communication device. An example of a characteristic Internet telephone network system is described. Further, the connection destination determination unit continuously performs 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 input end of the communication device. An example of an Internet telephone network system that performs

As described above, when searching the IP address table entry for each digit of the telephone number, before performing the entry search for all digits,
It is assumed that there are many address information candidates when only one remains. In such a case, when the other address information candidates no longer exist, the IP address conversion process is terminated, whereby a higher speed process can be realized.

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 is performed by the address conversion unit. The possible address information candidates are limited, and when the options are narrowed down to one, the address information candidates are adopted as the final conversion result without waiting for the input of all identification information. An example of an Internet telephone network system characterized by the above is described.

If the IP address table entry candidates are not narrowed down by checking the telephone numbers one digit at a time as described above, the telephone numbers of all digits are searched. As an intermediate case between the two,
For example, a method of searching the IP address table entry when an 8-digit telephone number is input can be considered.
This is based on the assumption that the search process will be successful if the search result matches about 8 digits as the prefetch of the search. Various numbers other than 8 digits are considered to be appropriate as the number of digits for this look-ahead. If you often call a 4-digit internal extension phone number, 4
By performing the search process once when a digit is input, it is possible to realize a comprehensive high-speed determination process. Also,
Even in these prefetching search processes, when a plurality of candidates remain, a more accurate search process can be realized by executing the search for the telephone number added again.

This means that, after the connection destination determination unit determines that the input of the communication device is completed, every time one character of the identification information is input from the communication device of the communication destination, the conversion process is performed by the address conversion unit. Limiting the possible address information, when the number of options is narrowed down to one after the identification information having a specific digit number is input, without waiting for the input of all identification information, An example of the Internet telephone network system characterized by adopting the above-mentioned address information as a final conversion result is explained.

Sixteenth Embodiment Here, the processing in the case where the present communication device adapter is connected to the communication device management device such as the PBX or the key telephone device will be described in more detail. FIG. 41 shows a usage pattern of a plurality of telephone lines by a general PBX or a key telephone device. There is no difference in communication processing when making a call from the communication device (telephone) to an area outside the PBX 190 as compared with the case of the existing communication device alone. The telephone number information at the time of calling the telephone, which is input to the communication device, is directly transmitted to the exchange of the central office, and the exchange generates a connection with the other party of the call. On the other hand, as shown in FIG.
When a call is made from the outside of the PBX 190, it is necessary to select a specific communication device in the PBX, and therefore the exchange 192 identifies the plurality of communication devices 10a to 10d supported by the PBX. It is necessary to send the lower digit information of the telephone number to the PBX side. This PBX1
The method of transmitting and receiving information between the 90 and the exchange 192 has a specification decided by the telephone company.

FIG. 42 shows a form of use of a plurality of telephone lines by the telephone device management apparatus to which the telephone device adapter is connected.
In order for the communication device adapter 22 to support a connection form with a communication device management device such as a PBX or a key telephone device, when a call is made from the outside of the PBX 190,
Exchange 1 as the actual intercom management system does
It is necessary for the telephone device to transmit the lower digit information of the telephone number received from 92 to the telephone device management device. At this time, the transmission / reception system between the exchange device 192 and the PBX 190 is exactly the same as the transmission / reception system between the exchange device 192 and the PBX 190. Regarding the transmission / reception method of the lower digit information of this telephone number, each telephone company discloses detailed specifications.

[0265] This means that the public line signal processing section of the communication device adapter is connected between the communication device and the communication device by P
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 communication devices connected to the communication device management device is provided as above. The public line of the communication device adapter,
Alternatively, when a call is made from the above IP network, by transmitting the call to the communication device management device,
An example of an Internet telephone network system is described in which a telephone device can be specified to make a telephone call.

In addition to the transmission / reception processing between the exchange and the general communication device, the telephone company may perform the transmission / reception processing for realizing the service in order to provide a special service with the above-mentioned device such as PBX. is there. In addition to the support for PBX and the like, there are those related to 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 local communication device, and the transmission / reception processing of the telephone number information is performed between the exchange and the communication device. Basically, the exchange performs a process of transmitting telephone number information to the telephone device of the person who made the call. In order to realize this also in the Internet telephone network system of the present invention, the telephone device adapter connected to the telephone device of the person making the call temporarily accumulates the telephone number information transmitted from the exchange, and Similar to the transmission / reception method of (1), the telephone number information is further transmitted to the telephone device.

This means that if the public line signal processing unit of the telephone device adapter has a contract for the number display function (number display function) in the telephone service of the telephone device on the public line, the other party of the telephone call Of the communication device by transmitting identification information for identifying the communication device to the communication device when a call is made from the public line of the communication device adapter or the IP network. 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 FIG.

Since the above service is the service of the exchange on the public line, in order to support the same function on the IP network, the calling device adapter of the calling user can This can be realized by transmitting the telephone number information of the calling party to the telephone device adapter.

This means that the public line signal processing unit of the communication device adapter has a contract for the number display function (number display function) in the communication service on the public line of the communication device of the other party of the call. When calling from the IP network of the communication device adapter, the identification information for identifying the communication device is
An internet telephone network system characterized by being able to display the identification information of our calling device on the display device of the calling device of the calling party by transmitting to the calling device adapter of the calling party. An example is described.

Further, regarding the above number display function (number display function), by entering non-notification information which is a special number digit (eg, 184 etc.) at the beginning of the telephone number, the call destination is called. You can refuse to send the number information. The telephone device adapter for making a call via the public line does not need any special communication processing because it only needs to send the telephone number including the above-mentioned special number digit input to the exchange as it is. The telephone device adapter that can make a telephone call must intervene in the refusal communication process for requesting telephone number information between the exchange and the telephone device. Further, when making a call via the IP network, if the input of the above-mentioned special number digit is confirmed, the telephone number information is not transmitted to the telephone device adapter of the person who can make a call. Further, the telephone device adapter of the person who can make a call needs to reject the transmission of the telephone number information to the telephone device as in the communication processing of the exchange.

This means that the public line signal processing unit of the communication device adapter has a contract for the number display function (number display function) in the communication service on the public line by the communication device on the other end of the call. When making a call from the IP network of the communication device adapter, the identification information for identifying the communication device,
When the number digit of the number non notification is added and the call is not sent to the above communication 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 communication device of the other party of the communication partner can be prevented from displaying the identification information of the communication device of the other party.

As for the service related to the number display function (number display function) described above, the telephone company publishes the specifications of the communication processing method between the exchange and the calling device. The above functions can be implemented in.

Seventeenth Embodiment The maintenance setting function described in the fourth embodiment allows the user to set the control information unique to the setting information storage unit. However, if there is an error in the setting, a normal setting is made in the telephone device adapter. Processing cannot be executed. For example, if the IP address or netmask of the telephone device adapter is incorrect, all processing to access the IP network will fail. Therefore, when an apparent error in the set value is detected by executing the process in the telephone device adapter, the user is notified of the error in the set value. As means for notifying the user, for example, a setting error is displayed when the telephone receiver is picked up by displaying a warning lamp or a display screen on the telephone device adapter or trying to use the connected telephone device. Send a warning tone.

This means that the IP network communication processing unit or the public line signal processing unit uses the IP network data read / write unit by the user, or
As a result of setting the inside of the above-mentioned communication device adapter by the telephone input data light part, when the call process cannot be executed due to the setting error during the whole call process, a warning is given to the display device of the above-mentioned communication device adapter. An example of the Internet telephone network system characterized in that the user can be guided to correct the setting error by performing the display as shown in the figure or transmitting a sound indicating a warning to the connected telephone is explained.

In the above, the case where the set IP address or the like is incorrect for the access to the IP network is taken as an example, but regarding the access to the IP network,
A warning can be issued in the same manner as described above, because the IP network cannot be accessed because the connected router is out of order or the IP network is disconnected.

This means that the IP network communication processing unit or the public line signal processing unit is

An example is described.

Therefore, also in the above warning function, when the failure of the router is recovered or the broken IP network is newly recovered, normal IP network access can be resumed. Has
By stopping the conventional warning process and allowing the normal process to be started, it is possible to save the user the trouble of releasing the warning function.

This means that the IP network communication processing unit or the public line signal processing unit is
As a result of setting the inside of the above-mentioned communication device adapter by the P network data read / write unit or the telephone input data write unit, when the call process can be executed due to the setting error during the whole call process, The IP network connected to the communication device adapter or the public line is disconnected, or the telephone or IP network device connected to the communication device adapter is not operating due to a failure or a stop. , When the state becomes to work due to the recovery process of the peripheral device, the display indicating the warning is stopped on the display device of the communication device adapter, or the sound indicating the warning is stopped to the connected telephone. Internet telephone network characterized by being able to notify the user that the peripheral device has recovered from the abnormality It describes an example of the stem.

Eighteenth Embodiment In the above eighth embodiment,
The message POST has been described as the message for transmitting the voice data to the HTTP relay server. However, it is also possible to use messages such as GET and PUT other than POST. However, in the case of GET, it is basically necessary to embed it in a field called a URL, so there is an upper limit to the data size. Since POST and PUT can have a data body part in addition to various fields called a header part, there is basically no upper limit to the size (however, there may be restrictions due to the implementation of HTTP proxies, etc.).

When voice data is obtained from the HTTP relay server as a GET message, the chopped voice data can be repeatedly obtained by issuing a GET message, but it has the first size. Issue a GET message to obtain data of the second size that is sufficiently larger than the voice data of the call time. Once the voice data can be captured, the voice data of the first size is repeatedly cut into pieces. It is also possible to obtain.

According to the HTTP specification, the message transmission / reception process is executed after the client side and the server side are first connected. Basically, there is a processing time required to create this connection, so basically in real-time voice data transmission / reception processing, once a connection has been created to improve performance, that connection should be created as much as possible. It is desirable to hold and send and receive voice 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 depending on the relay situation regardless of the convenience of the client side and the server side. There is also. In such a case, a new connection is made to restart the transmission / reception process of the audio data.

In addition to HTTP, not only HTTP but also this telephone device adapter and HTTP relay server use I
It communicates on the P network. TCP is a connection-type communication protocol, and it is necessary to establish a connection (connection) before transmitting / receiving data. In this TCP communication process, 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, a fixed timeout value is set for all processing of transmitting and receiving data via the IP network, and waiting for a reply from the communication partner, etc. If there is no response even if the processing exceeds the timeout value, it is possible to reconnect and restart the IP network access processing from the beginning to avoid a system hangout.

This means that after the call device adapter has made a connection to the HTTP communication processing unit of the relay server in order to transmit a voice data packet, the H
An example of an Internet telephone network system characterized by storing voice data in an encoded format in a message of a method such as GET, POST, PUT and the like defined by TTP and transmitting the voice data is described.

This also means that the telephone device adapter
After connecting to the HTTP communication processing unit of the relay server to receive the voice data packet, the voice data is encoded in the response message of the message of the method such as GET specified by HTTP. An example of an internet telephone network system characterized by storing and receiving in the above is described.

This also means that the telephone device adapter
After connecting to the HTTP communication processing unit of the relay server in order to receive a voice data packet, the size of voice transmission / reception data of a telephone call is larger than the size of voice transmission / reception data of a telephone action by a message of a GET method specified in HTTP It should be possible to store voice data in encoded format in the data body of the response message by obtaining data of a sufficiently large size, and to continue receiving the voice data as fragments whenever the voice data occurs. An example of a characteristic Internet telephone network system is described.

In addition, this means that the telephone device adapter
A connection is made to the HTTP communication processing unit of the relay server in order to send and receive voice data packets,
After sending and receiving the message of each method and its response message, do not disconnect immediately, continue,
An example of an internet telephone network system characterized by transmitting and receiving a message of each method and a response message thereof is described.

This also means that the telephone device adapter
A connection is made to the HTTP communication processing unit of the relay server in order to send and receive voice data packets,
While sending or receiving the message of each method or its response message, or immediately after the message is sent, if the connection is disconnected due to some reason, reconnect and continue to continue sending the message of each method and its response. An example of an internet telephone network system characterized by transmitting and receiving messages is described.

[0288] This also means that the telephone device adapter
A connection is made to the HTTP communication processing unit of the relay server in order to send and receive voice data packets,
When there is no response for the HTTP or TCP transmission / reception process even if a certain set period of time elapses for some reason during or immediately after transmitting / receiving the message of each method or its response message. In the above, an example of the Internet telephone network system is described, in which the connection disconnection process is performed, the connection is performed again, and the message of each method and the response message thereof are continuously transmitted and received.

[Embodiment 19] FIG. In the above-mentioned Embodiment 8, referring to FIG. 34, telephone call information management means 8200
Allows you to access the management area of the other party of the call,
I checked whether it was already on the phone (S75). In the nineteenth embodiment, an identifier that is call connection identification information is given to the call act itself (this identifier will be referred to as a session ID), and when making a call by the HTTP method, first, At the time of inquiring of the HTTP relay server as to whether or not a call can be made, when it is found that a call can be made, HT
The TP relay server adds a session ID to the call and confirms that the call can be made. (Basically, a session ID may be incrementally generated by a counter.) Based on this session ID, the HTTP relay server manages information about the call. If the communication device adapter on the user side also acquires this session ID as a call permission, it is possible to perform transmission / reception of voice data to / from the HTTP relay server while referring to the session ID and distinguishing from other calls. In the HTTP relay server, the source of this session ID, information about the call,
For example, it is possible to record and manage log information such as identification information of both call devices of the call, IP address information, call time, call start time, call end time and the like. It is also possible to perform billing work based on these management information.

This means that the relay server manages session information, which is a set of address information of the above-mentioned communication device adapters of both users when the user makes a call, as call connection identification information, and stores it in the voice data packet. An example of an Internet telephone network system characterized by storing the call connection identification information and transferring it on an IP network is described.

This also means that the relay server uses the session information, which is a set of address information of the above-mentioned communication device adapters of both users when the user makes a call, as the call connection identification information, and the call of the user is made. An example of the Internet telephone network system is described in which the call time, the communication packet amount, and the like can be stored and retrieved as log information each time the call is executed.

Embodiment 20. In the twentieth embodiment, when a call from a third party using another method is received during a call using three methods, that is, a call via a public line, a call via UDP via an IP network, and a call via HTTP. A communication device adapter equipped with a processing method for notifying the busy state will be described. Already in the sixth embodiment,
The form of call processing in which the three methods of public line, UDP, and HTTP coexist has been described. In addition, in the eighth embodiment,
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)
A case of using a telephone calling method using an e-mail according to an auto-col will be described.

As shown in FIG. 43, when a call is received from a third party while the call is made by the above three methods.
There are nine patterns shown in.

As described in FIG. 43, basically, the process of informing the busy state is to output a busy tone to the communication device of the third party. When a telephone call from a third party is sent via a public line, the telephone device switching device directly generates a busy tone, and in addition to the busy tone being generated from the telephone company's exchange, the telephone device adapter generates a busy tone and transmits it via the public line To do. However, in the latter case, a telephone call fee is paid to the telephone company because the telephone call state is set only by informing the busy state. When the telephone call from the third party is UDP, the telephone adapter that has made the telephone call reports the busy state, and the telephone adapter of the third party itself generates a busy tone and notifies the user. I try to hear the sound. Telephone call from a third party is HTTP
In such a case, when it is found by the inquiry to the HTTP relay server that the telephone is in the busy state, the communication device adapter itself of the third party generates a busy tone to let the user hear the sound.

With the above-described method, even when three types of telephone communication methods are mixed, it is possible to report the 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 above-mentioned reporting of the busy state. In this case, even if the third party makes a telephone call, it will make the user feel that he / she will not answer the telephone no matter how long the other party of the call waits. That will be the case.

[0296] This means that while the IP network communication processing unit or the public line signal processing unit makes a call by the user using any one of the communication methods of public line communication, RTP communication processing and HTTP communication processing. In addition, when the third user makes a telephone call by any of the above calling methods, it sends a busy tone to the third user's telephone device to notify the busy status. An example of an internet telephone network system characterized by what is possible is described.

[0297]

As described above, the above-described embodiment of the Internet telephone network system according to the present invention has the following effects.

When a telephone call can be made via the IP network when a telephone call via the IP network is possible and the telephone number cannot be converted into an IP address, or the calling device on the partner side is not connected to the IP network. Or if the telephone device adapter connected to the other party's telephone device is a device that is not compatible with the transmitting side telephone device adapter, when it is not possible to make a call on the IP network, the public network The effect is that you can make a call via.

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

Further, when the call information is received from the IP network as digital voice data, there is an effect that it can be transmitted to the call device as analog voice data.

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

If the calling device of the other party to which the call information is transmitted can make a call via the IP network, the IP network side can make a call. Otherwise, the public line side can make a call. By making a phone call, both can be automatically switched. For this reason, the caller can use the public line, I
There is an effect that the call information can be transmitted and received through either of the P networks.

After making a call via the public line, the telephone number of the own telephone apparatus and the IP address corresponding to the telephone number are notified to the telephone number of the other party, or the telephone number of the other telephone apparatus of the other party. Since the IP address learning unit for receiving the IP address corresponding to is provided, it is possible to eliminate the need for the caller to check the IP address of the other party in advance and set it in the address conversion table.

[0304] The conventional public telephone number and I
By storing the P-addresses in association with each other, it is possible to automatically make a call via the IP network after the next call is made.

Also, since two or more voice data other than one's own voice received from another call device to which the call device adapter of the present invention is connected via the IP network is mixed and voice output is performed. There is an effect that it is possible to hold a telephone conference via the IP network by three or more parties.

Also, the conference identification number is set in the conference call,
Since the conference identification number is designated by the caller who has requested the call at the time of the call request, there is an effect that a conference call via the IP network can be held between the identified participants.

[0307] Further, since the telephone set identification number is set in the telephone set connected to the telephone set adapter and the telephone set identification number is designated by the calling party who has requested the call at the time of the call request, the communication between the specified call sets Thus, there is an effect that a telephone conference can be held via the IP network.

Also, a password is assigned in advance to each caller who is scheduled to participate in the conference call, is managed for each conference call, and the password of each caller is entered when participating in the conference call. There is an effect that the collation can be performed and the conference call participants can be authenticated.

Also, control information generated for maintenance work can be input from an existing telephone connected to the telephone adapter, a telephone, a general-purpose personal computer, etc., and a setting information storage section is provided according to 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 telephone device adapter. Further, there is an effect that a user or the like can easily perform maintenance work by using a conventional device (a telephone device such as an existing telephone or a general-purpose personal computer).

[0310] In addition, since permission information regarding a telephone conference can be registered by inputting it from a telephone connected to a telephone device adapter or a personal computer connected to an IP network, new registration or change or deletion of registered information occurs. This has the effect of facilitating the registration change work of the permission information regarding the telephone conference, which is considered to be frequent.

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

Also, for a firewall that does not allow the use of an arbitrary UDP port, a very limited specific UD
By setting a 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 it is possible to perform communication processing of voice data that exceeds the firewall.

Further, since it is possible to scan the usable UDP ports for the firewall which does not allow the use of any UDP port, even if the available UDP port is unknown, There is an effect that it is possible to find out and perform communication processing of voice data.

In many cases, the UDP port cannot be used in the firewall, but since the HTTP port is normally open, voice data is communicated as an HTTP message. Therefore, there is an effect that the call processing via the IP network can be realized even for a robust firewall.

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

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

Also, when the telephone device adapter makes a call via the IP network, security is provided to prohibit illegal access at the boundary from the IP network area to which the telephone device adapter is connected and managed to the external IP network area. For the purpose of firewalls, by investigating the existence of HTTP ports that can send and receive data, it is possible to send and receive voice data.
There is an effect that a P port can be specified and a voice data call can be made using the HTTP port.

Also, the header part of the packet of voice data to be communicated is uniquely compressed. Therefore, the packet size can be made smaller than the standard packet size, and the network traffic can be reduced. Moreover, since the packet of the compressed audio data can be decompressed, the compressed packet information can be received. This has the effect of reducing network traffic.

Further, even if there is fluctuation in the transmission time of each packet of the voice data to be communicated, the packet is stored until it reaches a certain size at the time of reception and sent out to the analog reproducing side, so that the network traffic situation is unclear. Even if it is stable, it has the effect of maintaining stable call quality. Also, I
When transmitting a digital voice data packet to the destination telephone via the P network, the digital voice data packet to be transmitted is created, and the data required before being stored in the transmission buffer whose buffer size can be changed and sent out It is provided with a transmission buffering unit that performs processing for adding only the packet to packet assembly, and has an effect that an optimum digital voice data packet transmission mode can be realized according to the network traffic situation and high-quality voice data transmission can be performed.

When transmitting each packet of voice data to be communicated, the packet size is reduced when the amount of network traffic is small, and is increased when the amount of network traffic is large. Even if the situation is unstable, it has the effect of maintaining stable call quality by not affecting network traffic.

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

When the amount of network traffic increases at the time of transmitting each packet of voice data to be communicated, the voice data packet which does not affect the call quality under a condition such as a certain volume level is not transferred. Therefore, even if the amount of network traffic increases, there is an effect that stable call quality can be maintained.

Also, the reception timing of each packet of voice 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 copies by the redundant packet issuing unit is adjusted, Since at least one of the adjustments of the conditions for reducing the number of packet information transmissions by the generation filtering unit is performed, it is possible to perform optimal communication processing according to the latest situation of network traffic, This has the effect of maintaining stable call quality.

Further, 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 the data indicating the network traffic condition in a cycle such as one day or one week, the average value is obtained. It is possible to control the optimum communication processing corresponding to various network traffic conditions, and it is possible to maintain stable call quality.

Further, since the firewall can access the external Internet by HTTP, the telephone device adapter allows telephone call and telephone call processing via the HTTP relay server. There is an effect that it is possible to make a call via the IP network without having to make any setting changes. Also, the voice processing can be realized by temporarily storing the voice data in the HTTP relay server and having the telephone device adapter connected to another telephone that needs the voice data obtain the voice data. There is an effect that can be done. Also, when it is found that the communication device adapter of the called party is blocked by the firewall, HTTP is always reported at an appropriate time interval in order to report that the calling device adapter of the called party is being called. For the relay server, the call status of the call device adapter of the call destination of the telephone call information management unit that stores the call status of each telephone is set to H.
When it is determined by the TTP polling unit that a telephone call is made, the telephone device adapter that made the telephone call has the effect of making a telephone call via the HTTP relay server by HTTP access. In addition, when it is found that the communication device adapter of the call destination is blocked by the firewall, the public line signal processing unit notifies the call device adapter of the call destination that a call is being made. Only telephone call information is transmitted via a temporary public line, and the telephone device adapter on which the call is made is HTT.
There is an effect that a call can be made via the HTTP relay server by P access and the call information can be exchanged with each other via the HTTP relay server.

Further, in the HTTP relay server, after the processing of the first connection negotiation with each communication device adapter, the HT
The TP connection changing unit changes the HTTP and TCP connections directly to the connection between both adapters. The call data is sent and received after the first connection negotiation between the call device adapters, but this processing load is quite heavy. Therefore, the call data is sent and received directly without passing through the HTTP relay server. If it is done between the two communication device adapters, the processing load of the HTTP relay server is reduced,
Even if many users make calls and the call processing is concentrated, the processing can be continued without delay, and the call quality can be maintained.

[0327] Also, since the transmission / 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 person makes a call and the call processing is concentrated, the processing can be continued without delay,
This has the effect of maintaining call quality.

Also, the transmission / reception of the call data is carried out by processing in the HTTP relay server as I in the packet of voice data.
Since the IP address of the P header part and the port number of the TCP header are directly converted to the IP address and port number of the telephone device adapter of the final destination, the processing load of the HTTP relay server is reduced, so many Even if the user makes a call and the call processing is concentrated, the processing can be continued without delay, and the call quality can be maintained.

Even if efficient communication processing is performed in the HTTP relay server, if the number of users and the number of telephone device adapters requesting call processing increase, one H
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, an HTTP relay server with few users currently available is identified, and a candidate used in the call processing. Specify the HTTP relay server of. By distributing the call processing of each communication device adapter to the plurality of HTTP relay servers, there is an effect that each user can maintain a comfortable call state.

The name of the calling device adapter is used as the identifier of the calling device adapter that is known in advance among the calling device adapters that transmit and receive the call information. Therefore, the telephone device adapter can be used in a network form in which the IP address is not fixed and is dynamically given. The case where the IP address is dynamically assigned is when the DHCP server gives the IP address, or when the telephone equipment adapter dials up to the Internet service provider (ISP) and has the IP address assigned at the time of connection. In some cases, even if fixed IP address allocation is not done,
There is an effect that it is possible to realize a connection negotiation process with a communication partner of the communication device adapter.

Also, the Internet telephone can be used by making a dial-up connection to an Internet service provider (ISP) at a necessary time instead of in a network environment which is always connected to an IP network. In other words, there is an effect that the Internet telephone can be used by a dial-up connection that can be relatively easily performed in a general home, even if the user does not set up or contract the constant connection mode.

[0333] Also, in a network environment which is not always connected to the IP network, dial-up connection is made to the Internet service provider (ISP) at a necessary time. As a device for making this dial-up connection,
Use the terminal adapter that is widely used for personal computers. The terminal adapter has a built-in device such as a modem for communicating with a public line or ISDN. By providing the communication device adapter with a processing device for the RS232C serial port that can be more easily mounted than these devices, it is possible to reduce the implementation cost of the communication device adapter by leaving the device with a relatively large cost to the terminal adapter side. There is.

[0333] Further, even if both parties making a call using the calling device terminate the call and put the handset of the calling device, the calling device adapter holds the connection of the public line, so that the IP address information There is an effect that can be sent and received.

Also, when a call is being made using the call device, the other party who has sent the call information after a lapse of a predetermined time after the end of the call and the side transmitting the call information puts the handset Send a tone signal to notify the side of the disconnection. For this reason, the call device adapter maintains the connection of the public line when the caller's call is completely terminated and both handsets are placed, and therefore, the effect of reliably transmitting and receiving the IP address information is obtained. is there.

[0335] Further, since a voice notifying the end of the call, such as busy tone, is generated to the other party who transmits the call information, the other party who sends the call information can surely know the end of the call. This has the effect of allowing the receiver to be placed.

[0336] Also, when trying to use the telephone device while transmitting / receiving the IP address information, it is made possible to hear a voice such as busy tone from the handset. Therefore, do not use the telephone device while transmitting / receiving the IP address information. There is an effect that can be.

If the calling device is to be used during the transmission / reception of the IP address information, the input of the identification information of the other party of the call is accepted, and when the transmission / reception of the IP address information is completed, the accepted identification information is received. Perform the process to connect to the destination. The IP address information transmission / reception process is not a process that takes many minutes. Therefore, a user who wants to make a call can use the call device without waiting, and there is an effect that convenience can be improved.

Further, it is determined that the input of the identification information is completed when nothing is input even after a certain period of time. Therefore, the user who makes a call can omit the input of information for determining the end of input of the identification information, and the convenience can be improved.

Further, the judgment of the end of inputting the identification information is made by inputting the specific information. Therefore, there is an effect that it is possible to reliably determine the end of input and accurately input the identification information.

Further, the determination of the end of the input of the identification information is made by specifying the size of the identification information input by the communication carrier information and comparing the size of the specified identification information with the size of the input identification information. I decided to do it. Therefore, the user making the call can input the identification number in the same manner as the conventional method, and the input of the identification information can be surely completed, so that the convenience can be improved.

Also, every time one character of the identification information is input, the address conversion unit narrows down the 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 becomes one while the candidates are being narrowed down, 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 forming the input identification information exceeds a predetermined number, the address conversion unit converts the character information into IP address information. Therefore, the IP address is converted without waiting for the completion of the input of all the identification information, so that the processing can be performed at high speed.

Further, the learning process by the IP address learning unit is performed on both the caller side and the callee side. Therefore, it is possible to provide a highly convenient Internet telephone network system because it is possible to learn by simply making a call without being aware of the identification information and IP address information of the other party.

Also, it is possible to prevent the learning process by the IP address learning unit from being performed when a telephone call is made. Therefore, when the caller makes a call for sales purposes, for example, the identification information of the other party and the IP
Since it is possible not to register the address, it is possible to prevent the storage area of the address conversion table from being unnecessarily used.

Further, when a call is made, it is possible to prevent the caller from performing the learning process by the IP address learning section of the communication device adapter of the other party. 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 there is an effect that it is possible to provide an Internet telephone network system that is highly convenient for the user.

Also, the information registered in the address conversion table can be deleted by the user. Therefore, there is an effect that the storage area of the address conversion table can be effectively utilized.

Further, 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 immediately correct the control information, there is an effect that it is possible to provide a highly convenient Internet telephone network system for the user.

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

Further, when the communication device is changed from the non-usable state to the usable state, the user is notified of the usable state. Therefore, the user can immediately know that the device is ready for use, and there is an effect that an Internet telephone network system that is highly convenient for the user can be provided.

If a connection request is made by a third party while the call is being made by one of the public line call, the RTP communication process call, and the HTTP communication process call, the third party requests the connection. The status of busy is notified. Therefore, there is an effect that it is possible to provide an internet telephone network system that is highly convenient for users.

Also, the relay server is configured to add session information, for example, a session ID, to the call activity. Then, the session information is included in the packet information for transmitting the call information, and the packet information is transmitted. For this reason,
The relay device has an effect of managing the call contents by using the session information in the packet information.

Further, the relay server manages the call contents using the session information. Therefore, the relay server can perform, for example, billing work based on the managed call content, and has an effect that the Internet telephone network system can be used in various ways.

Further, the telephone device adapter is adapted to perform HTTP access to the relay device by using at least one of GET, PUT, and POST methods. Therefore, there is an effect that the relay server can be accessed like a Web server.

Also, the relay server is configured to return the call information in the response message to the request using the method. Therefore, the telephone device adapter has an effect of being able to receive the telephone call information from the relay server by HTTP access in which the relay server is regarded as a Web server.

When the relay server is accessed from the telephone device adapter to receive the telephone call information, a method for receiving the telephone call information of a size sufficiently larger than the actual telephone call information is issued. Therefore, each time a call is made and call information is generated, the call information can be repeatedly received.

Further, the connection between the telephone device adapter and the relay server is made to continue after the transmission of the message for requesting the call information and the reception of the message responded to the request are completed. . Therefore, there is an effect that the processing time required for connecting the telephone device adapter and the relay server can be saved, and the telephone call information can be transmitted and received in real time.

Further, the connection between the telephone device adapter once connected and the relay server may be unintentionally cut off. In this case, since the connection is made again, the user can receive the call information from the relay device without being aware of the disconnection.

Further, if there is no response from the relay server even after the lapse of a predetermined time, disconnection is made and connection is made again. Therefore, the user can receive the call information from the relay device without being aware of the state of the relay server.

Further, the identification information is notified to the communication device management apparatus to which the communication device adapter is connected.
Therefore, the communication device management device has an effect of being able to specify a predetermined communication device from a plurality of managed communication devices.

In addition, a call is 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 of being able to confirm the identification information of the communication partner.

Further, even when a telephone call is made through the IP network, the telephone device adapter notifies the telephone device having the number display function of the identification information. Therefore, even if a call is made via the IP network, there is an effect that the identification information of the call partner can be confirmed.

Further, the non-notification information for instructing not to display the number is included in the identification information. For this reason,
When the non-notification information can be confirmed in the identification information, the telephone device adapter can not notify the other party of the call of the identification information, which has the effect of improving the convenience for the user.
