When a call is transmitted from the IP telephone terminal 2-1 to the IP telephone terminal 2-2, the central processing unit 10 detects the transmission and transmits / receives control data to / from the IP telephone terminal 2-2 via the LAN interface circuit 13. As a result, a communication path for transmitting voice data is established, and thereafter, voice data is transmitted and received between the IP telephone terminals 2-1 and 2-2 by a peer-to-peer connection. A call is made in this manner. Note that the peer-to-peer connection is a connection method in which IP terminals are directly connected to each other by IP without passing through a time-division switch, and can be used on an IP network infrastructure.
[0037]
[Description of operation]
Now, the operation of the IP telephone terminal system of the present invention configured as described above will be described in detail with reference to FIGS.
[0038]
1. Login
First, a sequence for connecting the IP telephone terminal 2 to the LAN 3 and setting it in a login (usable) state will be described with reference to FIG.
[0039]
There are two modes for setting the IP telephone terminal 2 in the login state, that is, an automatic login mode and a manual login mode. The automatic login mode is a mode in which an extension number is automatically assigned just by connecting the IP telephone terminal 2 to the LAN 3 so that the IP telephone terminal 2 can be used as a telephone. On the other hand, in the manual login mode, when the IP telephone terminal 2 is connected to the LAN 3, the user is required to enter a user authentication number and a password, and the user enters his / her own user authentication number and password to enter the user authentication number. In this mode, the extension number of the corresponding individual is assigned and the IP telephone terminal 2 can be used as a telephone.
[0040]
1.1 Automatic login
The sequence of the automatic login mode will be described assuming that the IP address of the IP telephone terminal 2 to be logged in is “IP208”.
[0041]
When the IP telephone terminal 2 (IP208) is connected to the LAN 3 (step A1 in FIG. 14), the IP telephone terminal 2 (IP208) notifies the IP-PBX 1 of an initial setting request including the information of the IP address “IP208”. (Step A2). The IP-PBX 1 that has received the initialization request searches the received information for the registration of the corresponding IP address “IP208” in the data on the database 12 (FIG. 5) (step A3).
[0042]
As a result of the search, as shown in FIG. 5, since the registration of the IP address “IP208” exists, the IP address “IP208” is detected (YES in step A4), and the IP telephone having the IP address “IP208” is detected. Terminal 2 (IP 208) is determined to be in the automatic login mode. At the same time, based on the stored contents of the database 12 in FIG. 5, the extension number data necessary for automatically bringing the IP telephone terminal 2 (IP 208) into the login state is the extension number 104, and the user authentication number is USR4. Understand (Step A11).
[0043]
Subsequently, the IP 208 is set in the column of the IP address corresponding to the user authentication number USR4 of the IP telephone terminal 2 (IP 208) in the login terminal setting memory shown in FIG. 7 (step A12). As a result, IP telephone terminal 2 (IP 208) enters the log-in state. Further, in the stored contents of the data (FIG. 6) on the database 12, the own seat IP address corresponding to the user authentication number USR4 is searched to obtain the own seat IP address “SIP4”. Thereafter, a service start notification with the extension number “ext. 104” and the own seat IP address “IP4” is transmitted to the IP telephone terminal 2 (IP 208) (step A14).
[0044]
Upon receiving the service start notification, the IP telephone terminal 2 (IP 208) is automatically connected to the IP telephone terminal 2 (SIP 4) at his / her seat via the LAN 3 in a peer-to-peer manner. As a result, the personal information stored in the database unit 22 of the IP telephone terminal 2 (SIP4) at the seat can be downloaded (step A15) while preventing leakage to the outside. As a result, an operating environment for using the IP telephone terminal 2 (IP208) as the IP telephone terminal 2 (SIP4) at the user's seat has been established. After the downloading of the personal information is completed, the login of the IP telephone terminal 2 (IP208) is completed (step A16), and thereafter, the IP telephone terminal 2 (IP208) can be used as the extension number "extension 104".
[0045]
1.2 Manual login
The sequence of the manual login mode will be described assuming that the IP address of the IP telephone terminal 2 to be logged in is “IP11”.
[0046]
When the IP telephone terminal 2 (IP11) is connected to the LAN 3 (step A1 in FIG. 14), the IP telephone terminal 2 (IP11) notifies the IP-PBX 1 of an initial setting request including information on the IP address “IP11”. (Step A2). The IP-PBX 1 having received the initialization request searches the database 12 for a registration of the corresponding IP address “IP11” from the received information (step A3).
[0047]
As a result of the search, if it is found that the registration of the IP address “IP11” does not exist in the data (FIG. 5) on the database 12 (NO in step A4), the IP telephone terminal 2 (IP11) whose IP address is IP11 is manually operated. It is determined that the mode is the login mode. Thereby, IP-PBX 1 notifies user input request to IP telephone terminal 2 (IP11) (step A5).
[0048]
The IP telephone terminal 2 (IP11) that has received the user input request displays a login prompt (FIG. 11) on the screen display unit 21 (step A6), and waits for a user input. From the input processing unit 20 of the IP telephone terminal 2 (IP11), the user inputs a user authentication number (here, “USR26”) in the Login part of the login prompt and a password (here, “PW26”) in the Password part of the login prompt. (Step A7). Thereby, a user input response including the user authentication number (USR26) and the password (PW26) is returned from the IP telephone terminal 2 (IP11) to the IP-PBX 1 (step A8).
[0049]
The IP-PBX 1 that has received the user input response searches the data (FIG. 5) in the database 12 using the user authentication number (USR 26) received from the IP telephone terminal 2 (IP11) as a key, and finds the corresponding extension number “extension 126 "And the password" PW26 "(step A9). Then, the detected password “PW26” is collated with the password “PW26” received from the IP telephone terminal 2 (IP11) (step A10). If the collation results are not identical (NO in step A10), the user input request is transmitted again (step A5).
[0050]
Here, since the collation results match (YES in step A10), the IP address “IP11” is set in the column corresponding to the user authentication number USR26 in the login terminal setting memory shown in FIG. 7 (step A12). Further, in the data on the database 12 (FIG. 6), the own IP address corresponding to the user authentication number USR26 is searched (step A13), and the own IP address "SIP26" is obtained. Thereafter, a service start notification with the extension number “extension 126” and the own seat IP address “SIP26” is transmitted to the IP telephone terminal 2 (IP11) (step A14).
[0051]
Upon receiving the service start notification, the IP telephone terminal 2 (IP 11) is automatically connected to the IP telephone terminal 2 (SIP 4) of the user's seat via the LAN 3 in a peer-to-peer manner. As a result, the personal information stored in the database unit 22 of the IP telephone terminal 2 (SIP4) at the seat can be downloaded (step A15) while preventing leakage to the outside. As a result, an operation environment for using the IP telephone terminal 2 (IP11) as the IP telephone terminal 2 (SIP4) at the user's seat has been established. After the download of the personal information is completed, the login of the IP telephone terminal 2 (IP11) is completed (step A16), and thereafter, the IP telephone terminal 2 (IP11) can be used as the extension number "extension 126".
[0052]
In the above-described automatic login mode, the user can use the user authentication number USR4 corresponding to the self-seat IP telephone terminal 2 (SIP4) as the self-seat IP telephone terminal 2 (SIP4) only by the IP telephone terminal 2 (IP208) registered in the database 12. Could be used. On the other hand, according to the manual log-in, even if the user uses an arbitrary IP telephone terminal 2, the user enters the user authentication number and the password to change the IP telephone terminal 2 to the own IP telephone terminal 2 (SIP4). Can be used as
[0053]
2. change Password
Next, a sequence when the password for the user authentication number is changed from the IP telephone terminal 2 will be described with reference to FIG. The IP address of the IP telephone terminal 2 used here is “IP208”, the user authentication number is “USR4”, the old password is “PW4”, and the new password is “NP4”.
[0054]
After the IP telephone terminal 2 (IP208) is logged in according to the sequence of FIG. 14, the password change button 20-1 (see FIG. 4) provided in the input processing unit 20 of the IP telephone terminal 2 (IP208) is pressed (see FIG. 4). Step B1 in FIG. 15). Thus, a password change request is notified from IP telephone terminal 2 (IP 208) to IP-PBX 1 (step B2).
[0055]
IP-PBX 1 having received the password change request transmits a user input request to IP telephone terminal 2 (IP 208) (step B3). Upon receiving the user input request, the IP telephone terminal 2 (IP 208) displays a password change prompt (FIG. 12) on the screen display unit 21 (step B4), and waits for user input. From the input processing unit 20 of the IP telephone terminal 2 (IP208), the user inputs his / her user authentication number “USR4” to the Login part of the password change prompt and the old password “PW4” to the Old Password part of the password change prompt (step). B5). Since the password is changed in the login state, the user authentication number has already been input (step A7 in FIG. 14), but the user is required to input the password again when changing the password.
[0056]
When the old password “PW4” is input, the password change prompt is switched as shown in FIG. 12, so the user inputs the new password “NP4” twice into the New Password section of the password change prompt (step B5). This is to prevent a user's password setting error. As a result, a user input response including the user authentication number, the old password, and the new password (input twice) is returned to the IP-PBX 1 (step B6).
[0057]
The IP-PBX 1 that has received the user input response searches the data (FIG. 5) on the database 12 using the user authentication number USR4 as a key and detects the corresponding password “PW4” (step B6). Next, the detected password “PW4” is collated with the received old password “PW4” (step B7). If the result of the comparison is a mismatch (NO in step B8), a screen display request (error: old password mismatch) is transmitted to IP telephone terminal 2 (IP208) (step B9). The IP telephone terminal 2 (IP 208) displays a message “Error: old password mismatch” on the screen display unit 21 (step B15).
[0058]
Here, since the collation results match (YES in step B8), collation is performed between the new passwords “NP4” that have been input and transmitted twice. If the collation results do not match (NO in step B11), a screen display request (error: new password mismatch) is transmitted to IP telephone terminal 2 (IP208) (step B12). The IP telephone terminal 2 (IP 208) displays a message “Error: new password mismatch” on the screen display unit 21 (step B15).
[0059]
Here, since the collation results match (YES in step B11), the password in the column corresponding to the user authentication number “USR4” of the data (FIG. 5) on the database 12 is updated from “PW4” to “NP4” (step B11). B13). When the password is updated, the data on the database 12 (FIG. 5) becomes as shown in FIG.
[0060]
Thereafter, IP-PBX 1 transmits a screen display request (normal: password change completed) to IP telephone terminal 2 (IP 208) (step B13). When receiving the screen display request, IP telephone terminal 2 (IP 208) displays a message “Normal: Password change completed” on screen display unit 21 (step B15), and ends the password change process.
[0061]
3. Change login mode
Next, a sequence when the login mode for the user authentication number is changed from the IP telephone terminal 2 will be described with reference to FIG. The IP address of the IP telephone terminal 2 used here is “IP11”, the user authentication number is “USR26”, and the password is “PW26”.
[0062]
After making the IP telephone terminal 2 (IP11) log in according to the sequence of FIG. 14, the login mode change button 20-2 (see FIG. 4) provided in the input processing unit 20 of the IP telephone terminal 2 (IP11) is pressed. (Step C1 in FIG. 16). Thereby, a login mode change request accompanied by the IP address “IP11” is notified from the IP telephone terminal 2 (IP11) to the IP-PBX 1 (step C2).
[0063]
The IP-PBX 1 that has received the login mode change request searches the data (FIG. 5) on the database 12 for the received IP address “IP11” (step C3). As a result of the search, since IP 11 cannot be detected in this operation example (NO in step C4), the current login mode is determined to be the manual login mode. If the IP 11 exists (YES in step C4), the current login mode is the automatic login mode.
[0064]
After the current login mode is determined (in this case, the manual login mode), the IP-PBX 1 notifies the IP telephone terminal 2 (IP11) of a user input request accompanied by the detected login mode (step C7). Upon receiving the user input request, IP telephone terminal 2 (IP11) displays a login mode change prompt (FIG. 13) on screen display unit 21 (step C8). In the Login Mode section of the login mode change prompt (FIG. 13), "Self" indicating the current login mode, that is, the manual login mode, is displayed, and the user waits for input. The user selects “Self” or “Auto” (“Auto” in this operation example) in the New Mode part of the login mode change prompt (FIG. 13) from the input processing unit 20 of the IP telephone terminal 2 (IP11). To enter a new login mode (step C9).
[0065]
As a result, a user input response with the user authentication number and the new login mode is returned from IP telephone terminal 2 (IP11) to IP-PBX1 (step C10). The IP-PBX 1 that has received the user input response determines whether the received new login mode is manual or automatic (step C11). If the log-in mode is the manual log-in mode (NO in step C11), the data in the database 12 (FIG. 5) is searched using the user authentication number as a key, and the IP address in the corresponding column is deleted (step C12). . The user authentication number has already been input to the IP-PBX 1 at the time of login (step A8 in FIG. 14).
[0066]
In the present operation example, since the received login mode is the automatic login mode (YES in step C11), “IP11” is registered in the IP address column corresponding to the user authentication number USR26 in the data on the database 12 (FIG. 5) ( Step C13). When the login mode is changed, the data on the database 12 (FIG. 5) becomes as shown in FIG.
[0067]
Thereafter, IP-PBX 1 transmits a screen display request (login mode change completed) to IP telephone terminal 2 (IP11) (step C14). The IP telephone terminal 2 (IP11) that has received the screen display request displays a message “login mode change completed” on the screen display unit 21 (step C14), and ends the login mode change process.
[0068]
4. Logout
Finally, a sequence when the IP telephone terminal 2 logs out will be described with reference to FIG. The IP address of the IP telephone terminal 2 used here is “IP67”, and the USR authentication number is “USR1”.
[0069]
After the IP telephone terminal 2 (IP67) is logged in according to the sequence of FIG. 14, the logout button 20-3 provided in the input processing unit 20 is pressed (step D1 in FIG. 17). Thereby, a logout request is notified from IP telephone terminal 2 (IP67) to IP-PBX 1 (step D2).
[0070]
The IP-PBX 1 that has received the logout request deletes the IP address “IP67” at the location corresponding to the user authentication number USR1 in the login terminal setting memory (FIG. 7) (step D3). As a result, the login terminal setting memory (FIG. 7) becomes as shown in FIG. Further, in the data on the database 12 (FIG. 6), the own seat IP address corresponding to the user authentication number USR1 is searched to obtain the own seat IP address “SIP1” (step D4). The user authentication number has already been input to the IP-PBX 1 at the time of login (step A8 in FIG. 14).
[0071]
Thereafter, the IP-PBX 1 notifies the IP telephone terminal 2 (IP 67) of a user input request including the own seat IP address “SIP 1” and a login prompt (step D5). The IP telephone terminal 2 (IP67) that has received the user input request establishes a peer-to-peer connection with the IP telephone terminal 2 (SIP1) at his / her seat, and thereby switches from the IP telephone terminal 2 (IP67) to the IP telephone terminal 2 (SIP1). ) Is uploaded (step D6). This is to update the personal information stored in the in-seat IP telephone terminal 2 (SIP1) with the added, corrected, or deleted personal information obtained during the login.
[0072]
After the upload is completed, a login prompt (FIG. 11) is displayed on the screen display unit 21 of the IP telephone terminal 2 (IP67) (step D7), and the user waits for a user authentication number and a password to be input (= logout state). (Step D8).
[0073]
As described above, when the user logs in to the IP telephone terminal 2 using the arbitrary IP telephone terminal 2 at an arbitrary place and inputs his / her own user authentication number and password, The customized personal information is automatically downloaded from the IP telephone terminal, and the IP telephone terminal 2 and the personal information can be used as if they were at their own seat.
[0074]
【The invention's effect】
A first effect of the present invention is that even if an IP telephone terminal is located at an arbitrary place, the personal database set in the IP telephone terminal at the user's seat can be used as it is, so that the user can stay away from the user's seat. This means that it is possible to use the IP telephone terminal in the same working environment as being in the user's seat at any place.
[0075]
The second effect is that, by providing two types of modes for the login method of the IP telephone terminal, a manual login mode and an automatic login mode, a method of using the fixed terminal similar to the conventional PBX (automatic login mode) is provided. A service for the convenience of the user by providing a use method (manual login mode) in which a call can be made using an extension number at the user's seat even at an arbitrary IP telephone terminal at an arbitrary place. Is to be provided.
[0076]
Furthermore, the third effect is that each user has a dedicated user authentication number and password for the IP telephone terminal, and it is impossible for a third party to use the terminal work environment, so that a third party cannot use the terminal work environment. It is possible to prevent the personal database environment from being changed or destroyed, which may have been performed when using his / her own IP terminal.
