2. Description of the Related Art Conventionally, voice communication services using a VoIP system for enterprises or general consumers have been put to practical use by various telecommunications carriers (for example, WAKWAK call go go by NTT ME). . Also, mainly for enterprises, an IP voice converter (VoIP GW) is installed in the enterprise, and VoIP GW or VoIP installed in a telecommunications carrier via a leased line or the like.
A service form is also envisioned in which a voice communication service is provided while interlocking with the control unit. However, in the above-mentioned network-provided voice communication service, one V
On the oIP system, there is no mechanism to arbitrarily set extension numbers for each group of companies, and if one VoIP system is shared and used by multiple groups, the same extension number is assigned so that it does not overlap. There are constraints.

A conventional product will be described. Taking commercially available VoIP products as an example, many of them use protocols such as H323 and MGCP (for example, Fujitsu Limited's IP Mediaserve series, Ci
Sonus Network, sco's VoIP product
s company's soft switch products, etc.). The mainstream of these methods is that a control unit called a gatekeeper or a call agent takes charge of conversion processing between an extension number and an actual telephone number based on a numbering plan table registered in advance.
However, in this case, many of these VoIP products have a limitation that only one extension number system can be set and managed when setting in the numbering plan table. Therefore, when different VOIP systems are shared between different groups. Had a problem that the extension number system was restricted. As a result, when implementing the VoIP service operation in which an arbitrary extension number is assigned to each group, it is necessary to install a plurality of VoIP systems and set and manage a plurality of control units / number plan tables. ,cost,
There was a problem in terms of system operation and centralized management of extension numbers.

On the other hand, on the VoIP system, a V that can assign any extension number to each group
There are also oIP products (for example, Oki Electric Co., Ltd. IP
(Stage CO model, etc.), there is a restriction that only a service form in which a plurality of individual VoIP GWs existing in a VoIP system are assigned in advance to each group and used. Therefore, in a single VoIP system, a usage pattern can be realized when the VoIP GW is shared by a plurality of groups or when the shared VoIP GW and the VoIP GW / VoIP communication terminal that is independently used by a specific group are linked. There was also the problem that I could not. In addition, in the conventional VoIP system, there are various cases such as communication between a telephone for circuit switching and a VoIP communication terminal (a terminal dedicated to VoIP communication or a personal computer that realizes VoIP communication) and a case of connecting between VoIP communication terminals. There is also a problem that the extension number cannot be flexibly set in the usage pattern.

[0005]

As described above, there are the following problems in using the conventional VoIP system. (A) Setting extension numbers for group users such as companies
When the management is performed, there is a problem that an arbitrary number system cannot be assigned to each group for an installation mode in which one VoIP GW is shared by a plurality of groups. As a result, in a mode in which a VoIP GW is shared and used on a certain VoIP system via a public telephone network, a leased line, or the like, there is a restriction on the extension number usage system. (B) In addition, a telephone for circuit switching communication and a P for circuit switching
BX, VoIP communication terminal (terminal dedicated for VoIP communication, VoIP
VoIP communication terminals are mixed because there is a constraint that flexible extension systems cannot be set and managed centrally and efficiently for communication service forms that use various communication terminals such as personal computer (PC) that realizes IP communication. In the form of communication service, there is a problem in using the group extension.

[0006] Therefore, an object of the present invention is to solve these problems of the related art and to make a VoIP connection via a telephone network or a private line.
Extensions for multiple groups when accessing the GW for shared use by multiple group users, when a specific group exclusively uses the VoIP GW, or when the specific group uses a PC or VoIP terminal having a VoIP function The number system can be set and managed centrally, and the extension number can be set and managed efficiently.
Another object of the present invention is to provide an extension number management device of a VoIP system that can also support service cooperation for sharing a VoIP GW with a plurality of groups. Further, another object of the present invention is to
In addition to the telephone number system, it is possible to set an extension to a VoIP usage number on a PC, and to provide an extension number management device for a VoIP system that can be integrated with various usage patterns. is there.

[0007]

In order to achieve the above object, an extension number management device of a VoIP system according to the present invention comprises:
A management number assigned to an IP voice conversion device for converting a voice signal and an IP packet, a voice input / output port number of the IP voice conversion device, a calling ID telephone number from a user (calling side), a user (calling side) ) Inputting a user number, a registration number given to the VoIP communication terminal, and a means for identifying a plurality of group IDs, and a connection to the IP voice converter via the telephone network.

1, 3-2 are connected. Further, the LAN 12 and the user premises type VoIP GW 11 are connected to the IP network 4 via the router 10, the dedicated line 7-2, and the switch 5, but the switch 5 is used instead of the router 10.
It is also possible to use the switch 5 together. In addition, as the user premises installed VoIP GW 11,
A method of implementing the oIP GW function or a method of using a VoIP GW of a type connected to the LAN 12 can be considered. In addition, NW equipment installation type VoIP GW3-1, 3
For -2, either of the telephone network 6 and the UNI connection can be adopted.

(Explanation of Operation) First, when a telephone call is started using the telephone 8 in the user A 15-1, the NW equipment installation type VoIP GW 3-1 is transmitted from the telephone 8 via the telephone network 6.
It is premised that it is once connected to. The voice signal from the telephone 8 is IP packetized (IP voice packetized) in the NW facility-installed VoIP GW 3-1 and passed through the IP network 4 to the user A 15-2 and the user B 16-1,1.
6-2, a telephone call is realized by connecting to the telephone 8, the PC 13, the VoIP terminal 14 and the like installed in the users C17-1 and 17-2.

At this time, the IP voice packet passing through the IP network 4 is converted back to a voice signal by the NW equipment installation type VoIP GW 3-2, taking the user A 15-2 and the user B 16-2 as an example, and the user C 17 In the case of -2 as an example, the voice signal is returned to the voice signal by any means of the user premises installed VoIP GW 11, the VoIP board installed in the PC 13 (or the VoIP software installed in the PC 13), and the VoIP terminal 14. . Further, user A15-
In the case of 1, a dial-in service type in which the telephone 8 is connected to the telephone network 6 via the PBX is also conceivable.

Next, when a telephone call is started using the telephone 8 in the user B 16-1, the telephone 8 is accommodated in the PBX 9 and the NW facility installation type Vo is received via the leased line 7-1.
Once connected to the IPGW 3-1. The voice signal from the telephone 8 is I in the NW equipment installation type VoIP GW3-1.

1 and the voice signal is transmitted from the telephone 8 when the voice signal is transmitted to the user premises VoIP GW11.
Is converted into an IP voice packet. When a call is started using the PC 13, the VoIP board installed in the PC 13 or the VoIP software installed in the PC 13 converts the voice signal into an IP voice packet.
At that time, a method of connecting a sound medium means such as a microphone, a speaker, and a handset to the PC 13 can be considered.

Further, a method of externally connecting a VoIP board mounted on the PC 13 or a VoIP adapter for executing a voice-IP packet conversion process to the PC 13 instead of the installed VoIP software is also conceivable. Finally, when a call is started using the VoIP terminal 14,
The VoIP terminal 14 converts the voice signal into an IP voice packet. The IP voice packet from the user C17-1 is passed through the leased line 7-2, for example, the user A15-

The advantage is that connection control of (P software) can be realized. In addition, NW equipment installation type VoIP GW3-1,3-
The number 2 can be shared among a plurality of groups, and the extension number for each group can be used.

(Management of group and extension number 1) FIG.
FIG. 2 is an image diagram of group identification information and extension number table stored in a DB in FIG. 1. In FIG. 2, 18
Is a group identification information and extension number management table, 18-
1 is a management part for group 1, 18-1-1 is a setting management part for identifying group 1, and 18-1-2 is a group 1
An extension number setting management part, 18-2 corresponds to a group 2 internal management part, and 18-3 corresponds to a group 3 management part. Although only the management tables up to the group 3 are described in this example, it is also possible that the number of groups is 4 or more.

In the example of FIG. 2, in the setting management part 18-1-1 for identifying the group 1, the calling ID (phone number of calling side), user number (ID / Password),
It is possible to enter one or more pieces of information of the port allocation number of the NW facility installation type VoIP GW3 and the VoIP GW number. This makes it possible to identify which group the user belongs to, according to the information described in each item.

Here, "calling ID (phone number of calling side)"
Is based on the telephone number of the calling user of the calling side, the group to which the user belongs to GK1.
Is a means to check authentication. The method using the "user number" is a means for the GK1 to perform authentication check as to which group the user belongs to based on the ID and password input by the user on the originating side. 'NW
The method using the port allocation number 'of the equipment-installed VoIP GW3 is the NW equipment-installed VOI that connects to the PBX 9.
Input / output port numbers on the audio signal side of the PGWs 3-1 and 3-2 (for example, for the user B16, ports # 1, 2,
It is a means for the GK1 to perform an authentication check of which group the user belongs to based on the setting (assignment of 3). Further, the method of using the'VoIP GW number 'means that all of a certain VoIP GW is assigned to a specific usage group. For example, the GW number is assigned to the user premises type VoIP GW 11 or the VoIP terminal 14, and the GW number is assigned. It can be attributed to the user C17.

Further, in the example of FIG. 2, in the extension number setting management part 18-1-2 of the group 1, the telephone number (including the telephone number in the case of dial-in) of the telephone set 8 belonging to the group 1 and the extension number are also included. Information of one or more of the correspondence relationship among the PCs, the registration number of the PC 13 (IP address, etc.), the registration number of the VoIP board installed in the PC 13, or the registration number of the VoIP software installed in the PC 13 (PC number. Corresponding to the extension number,
At least one of the correspondence relationship between the registration number (IP address or the like) of the VoIP terminal 14 and the extension number is set and managed.

After authenticating to which group the calling user belongs, the GK1 identifies the telephone number of the called party or the registration number of the called terminal based on the extension number input by the calling party ( = Number conversion) to connect. It is also possible to use an outside line number other than the closed extension number for a specific group, and in that case, a specific number that determines the outside line as the first value of the called telephone number entered by the calling user. A method of inputting a key or key can be considered. Further, in addition to the extension number system closed to a specific group, a method of using a setting management table of abbreviated numbers commonly available to all groups on the VoIP system is also conceivable. A method of classifying extension numbers into a plurality of subgroups and assigning different extension numbers to each subgroup is also conceivable.

(Management of Group and Extension Number 2) FIG.
It is a figure which shows the other structural example of the management table of a group and an extension number. In FIG. 3, 19 is a group identification information setting management table (19-1 is a group 1 identifying setting managing part, 19-2 is a group 2 identifying setting managing part, and 19-3 is a group 3 identifying setting). Management part),
20 is a registered group extension number setting management table (2
0-1 is an extension number setting management part for group 1, 20
2 is an extension setting management part for group 2 and 20-3 is an extension setting management part for group 3.

The example of FIG. 3 is an example in which the setting management table of group identification information and the setting table of extension numbers for each group are separated, which is suitable for an operation in which setting management items are separately managed. Further, an example in which the number of set groups is four or more can be considered. As described above, by adopting the configuration of FIG. 2 or 3, the VoIP GW or the VoIP
GK identifies the group to which the calling user belongs based on the registration number related to the terminal etc. and the number entered by the calling user, and efficiently searches for the extension number corresponding to the group.
It is possible to connect to the called party. Also, the telephone 8 (or PBX) for circuit switching communication, the PC 13, the Vo
Extension numbers can be assigned to various terminals such as the IP terminal 14.

(Processing of GK1) FIG. 4 is an explanatory diagram of processing of GK showing an embodiment of the present invention. The internal configuration of the GK1 can be considered in correspondence with both the physical configuration and the logical configuration. In FIG. 4, 1-1 is a communication call acceptance unit, 1-2 is an address resolution unit, 1-3 is a bandwidth management unit, 21 is a calling side VoIP terminal / GW (NW equipment installation type VoIP GW3, user home installation type VoIP). GW1
1, PC 13, VoIP terminal 14, etc.).

First, the communication call accepting section 1-1 is a part which performs processing for establishing a call when starting a new communication, and is composed of the address resolution section 1-2 and the bandwidth management section 1-3. The call setup is judged based on the cooperation. After receiving the connection start request from the calling VoIP terminal / GW 21, the communication call accepting unit 1-1 acquires group identification information about the calling user from the DB 2. When the calling user confirms that the calling user belongs to a specific group registered in advance, the communication call receiving unit 1-1 accepts the authentication and starts the call connection process.

Next, the address resolution unit 1-2, based on the cooperation with the communication call reception unit 1-1, calls the calling VoIP terminal / GW.
Based on the called party number information sent from 21, the destination V
The DB 2 is searched for address information (IP address etc.) regarding the oIP terminal / GW 22. At this time, if the called number sent from the calling side is in the extension number format, the address resolution unit 1-2 determines the telephone number format of the telephone 8 for circuit switching communication, the connection number to the PC 13 (IP address). etc),
DB of connection numbers (IP address, etc.) to VoIP terminals
The number plan table in 2 is searched (= number conversion).
On the other hand, when the called number sent from the calling side is in the number format (= outline number) for circuit switching communication, the address resolution unit 1
-2 only needs to search the address information (IP address or the like) of the NW facility installation type VoIP GW3 to be connected without performing extension / outline number conversion.

Here, the bandwidth management unit 1-3 uses VoIP.
The used band is managed based on the communication status of the system, the used band is managed based on the communication status of the VoIP system, and the quality maintenance of the VoIP communication and the call setting approval / disapproval processing at the time of receiving the communication call are performed. At this time, if there is a margin in the communication band, the communication call accepting unit 1-1 determines that the band managing unit 1-
In cooperation with 3, accept the request for communication call setup. At the time of judging the acceptance of the communication call, the address information (IP address etc.) of the destination VoIP terminal / GW 22 is the same as the originating VoIP terminal / GW 2
However, when the final destination terminal (end destination terminal) is the telephone 8 for circuit switching, it is transmitted from the NW equipment installation type VoIP GW3 on the receiving side via the telephone network 6. Telephone number information when calling is also sent. Based on the above procedure, the originating VoIP terminal / GW
The call connection from 21 to the destination VoIP terminal / GW 22 is started.

It should be noted that the call setup request from the calling side as seen from the GK1 may come not only from the calling VoIP terminal / GW21 but also from the GK that manages another communication zone. , GK1 carries out the processing relating to the call setting including the delivery of the destination information in the same manner as described above. On the other hand, for the destination side, the destination side VoIP
Not only the terminal / GW 22 but also GK that manages another communication zone is assumed. In this case as well, the call setting process including the delivery of the destination information is performed. By using the configuration and the processing method as shown in FIG. 4, group identification of use and extension number use of the called party are efficiently realized in a VoIP communication system environment in which various terminal types are mixed.

(Operation Sequence) FIGS. 5 to 10 are shown in FIG.
4 is a connection sequence chart up to the start of a call from a calling-side user in the case of the VoIP system based on FIG. Figure 5

Is an example of a connection to the telephone 8 of the user A15-
1 is a VoIP GW3-with NW equipment installed via a telephone network 6.
1 corresponds to the case where GK1 authenticates based on the calling ID of the telephone 8 once. Further, in FIG. 5, the telephone number of the calling telephone 8 is 03-3509-8200, and the telephone number and extension of the called telephone 8 are 0422-59-, respectively.
2904 and 3100.

In the example of FIG. 5, the telephone network 6 is transmitted from the calling telephone 8.
When the NW equipment-installed VoIP GW 3-1 is once accessed via the route, the NW equipment-installed VoIP GW 3-1 issues an input instruction of the called number to the telephone 8 on the calling side. Extension 3 of the destination telephone 8 from the originating telephone 8
After 100 is entered, the GK1 performs the calling ID authentication of the calling telephone 8 based on the information in the DB2, identifies the group to which the calling user belongs, and identifies the extension number and the destination telephone number. Conversion is performed. However, in GK1, when the calling ID authentication of the calling telephone 8 becomes NG, the connection process can be stopped without performing the process of connecting to the called party.

1 and NW equipment installation type VoIP GW3-2,
A call is started after performing a check (= communication start process) on basic settings such as a bandwidth used. By the way,
In the above example, the procedure is such that the GK1 carries out the calling ID authentication after receiving the input of the called party number from the calling side telephone 8. However, the calling side telephone 8 has the NW equipment installation type VoIP G.
Immediately after accessing W3, the procedure in which the GK1 executes the calling ID authentication, and only when the calling telephone 8 has the calling ID number (telephone number) registered in advance, the input instruction of the called number is executed. Can also be considered.

FIG. 6 is a sequence chart showing a connection example from the telephone 8 of the user A15-1 to the telephone 8 of the user A15-2. Calling user A15-1 telephone 8
This corresponds to the case where GK1 authenticates based on the user number (75114 in FIG. 6) input from In the example of FIG. 6, the NW equipment installation type V is transmitted from the calling side telephone 8 via the telephone network 6.
This corresponds to a case where the oIP GW 3-1 is once accessed, and an instruction to input the user number and the called number is issued to the telephone 8 on the outgoing side from the NW facility installation type VoIP GW 3-1. When the user number 75114 and the extension number 3100 of the destination telephone 8 are input from the calling telephone 8, GK1
Authenticates the user number based on the information in DB2 and also converts the extension number and the telephone number of the called party. However, in GK1, when the authentication of the user number is NG, the connection process can be stopped without performing the connection process to the destination. The subsequent connection procedure basically conforms to FIG.

In the example of FIG. 6, the procedure is such that the GK1 executes the user number authentication processing after receiving the input of the called party number from the telephone 8 on the calling side. Immediately after the 8 has accessed the NW equipment-installed VoIP GW 3, the GK 1 authenticates the user number, and only when the calling telephone 8 has the user number registered in advance in the DB 2, A procedure for executing the input instruction may be considered. Further, a method of simultaneously inputting the user number and the called party number and simultaneously inputting the user number in the calling telephone 8 at once by inserting the * key or the like is also conceivable.

FIG. 7 shows an example of connection from the telephone 8 of the user B16-1 to the telephone 8 of the user A15-2. The user number (input from the telephone 8 connected to the calling user B16-1) ( In FIG. 7, this corresponds to the case where GK1 authenticates based on 75114). In the example of FIG. 7, the calling telephone 8
More than exclusive line 7-1 NW equipment installation type VoIPGW3
-1 once access (= GW port is restricted), NW
The equipment-installed VoIP GW 3-1 issues an instruction to input a user number and a called number to the telephone 8 on the calling side.
On the calling side telephone 8, the user number 75114 and the extension number 3100 of the destination telephone 8 are input.
The user number is authenticated in cooperation with 2, and the extension number and the telephone number of the called party are converted. However, in GK1, when the authentication of the user number is NG, the connection process can be stopped without performing the connection process to the destination. The subsequent connection procedure basically conforms to the case of FIG.

In the example of FIG. 7, the user number and the destination number from the calling telephone 8 are entered simultaneously by inserting the * key between them, and the GK1 performs the user number authentication process. Although the procedure is performed, a method of separating the input instruction of the user number and the input instruction of the called number may be considered as in the example of FIG. FIG. 7 corresponds to an example of the calling side from the user B 16-1, but other than this, a method based on the calling ID authentication of the telephone 8 or a setting without authentication can be considered. In addition, in the example of FIG. 7, at the time of the first access (restriction of the GW port) of the NW facility installation type VoIP GW3-1, without inputting a specific number such as the * key or a specific number,
A method of dealing with the problem by simply raising the handset of the telephone 8 is conceivable. In addition, as another method, by simply inputting the destination number from the telephone 8, the NW equipment installation type VoIP GW
A method of collectively processing access and connection request to 3-1 (in this case, it is assumed that the input instruction of the called number is not output) can be considered.

FIG. 8 shows an example of a connection from the telephone 8 of the user C17-1 to the telephone 8 of the user A15-2, which is a user home installation type Vo installed in the calling user C17-2.
This corresponds to the case where a call is made from the telephone 8 under the IPGW 11. In FIG. 8, the user premises installation type VoIP GW1
1 is an example in which it is registered in the DB2 in advance that it is for the group of the user C17-1, and all extension calls from terminals under the user premises installed VoIP GW11 belong to the group to which the user C17-1 belongs. It is set to correspond.

In the example of FIG. 8, after inputting the extension number 3100 from the calling side telephone 8, the GK1 identifies that the calling side user belongs to the user C17-1 based on the information of DB2, Authentication of the calling user is omitted and extension numbers and recipients are converted. The subsequent connection procedure is based on FIG. In the example of FIG. 8, by inputting the extension number 3100 from the calling side telephone 8, the access to the user premises type VoIP GW 11 (GW port restriction) and the destination number are realized at the same time. Alternatively, a method of accessing a VoIP GW 11 installed in the user's home by entering a specific number such as the * key before inputting the called number is also conceivable.
