A call is made in this way. Note that peer-to-peer connection is a connection method in which IP terminals are directly connected to each other by IP without going 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. Log in
First, a sequence for connecting the IP telephone terminal 2 to the LAN 3 and entering a login (usable) state will be described with reference to FIG.
[0039]
There are two modes for bringing the IP telephone terminal 2 into the login state: an automatic login mode and a manual login mode. The automatic login mode is a mode in which an extension number is automatically assigned and the IP telephone terminal 2 can be used as a telephone simply by connecting the IP telephone terminal 2 to the LAN 3. On the other hand, in the manual login mode, when the IP telephone terminal 2 is connected to the LAN 3, the user authentication number and the password are required to be entered. This is a mode in which a corresponding personal extension number 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 that logs 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-PBX1 of an initial setting request including information on the IP address “IP208”. (Step A2). The IP-PBX 1 that has received the initial setting request searches the data on the database 12 (FIG. 5) from the received information for the registration of the corresponding IP address “IP208” (step A3).
[0042]
As a result of the search, since the registration of the IP address “IP208” exists as shown in FIG. 5, the IP address “IP208” is detected (YES in step A4), so the IP phone whose IP address is “IP208” Terminal 2 (IP208) 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 to automatically log in the IP telephone terminal 2 (IP208) is the extension 104, and the user authentication number is USR4. Yes (Step A11).
[0043]
Subsequently, the IP 208 is set in the IP address column 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, the IP telephone terminal 2 (IP208) enters a login state. Further, the self-seat IP address corresponding to the user authentication number USR4 is searched in the stored contents of the data on the database 12 (FIG. 6) to obtain the self-seat IP address “SIP4”. Thereafter, a service start notification is transmitted to the IP telephone terminal 2 (IP208) with the extension number “extension 104” and the own IP address “IP4” (step A14).
[0044]
The IP telephone terminal 2 (IP208) is automatically connected to its own IP telephone terminal 2 (SIP4) via the LAN 3 on a peer-to-peer basis by receiving this service start notification. As a result, the personal information stored in the database unit 22 of the IP telephone terminal 2 (SIP4) at the user's seat can be downloaded while preventing leakage to the outside (step A15). As a result, an operating environment for using the IP telephone terminal 2 (IP208) as the own IP telephone terminal 2 (SIP4) can be constructed. After the download of the personal information is completed, the IP telephone terminal 2 (IP208) completes login (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 that logs 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-PBX1 of an initial setting request including information on the IP address “IP11”. (Step A2). The IP-PBX 1 that has received the initial setting request searches the received information for whether the corresponding IP address “IP11” is registered in the database 12 (step A3).
[0047]
If it is found as a result of the search that there is no registration of the IP address “IP11” in the data on the database 12 (FIG. 5) (NO in step A4), the IP telephone terminal 2 (IP11) whose IP address is IP11 is manually The login mode is determined. Thereby, IP-PBX1 notifies a 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 user input. From the input processing unit 20 of the IP telephone terminal 2 (IP11), the user enters a user authentication number (here, “USR26”) in the Login portion of the login prompt, and a password (here “PW26”) in the Password portion of the login prompt. (Step A7). Thereby, a user input response with the user authentication number (USR 26) and the password (PW 26) 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) on the database 12 using the user authentication number (USR 26) received from the IP telephone terminal 2 (IP 11) as a key, and the corresponding extension number “extension 126”. And a password “PW26” are obtained (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 do not match (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). In addition, the self-seat IP address corresponding to the user authentication number USR26 is searched in the data on the database 12 (FIG. 6) (step A13), and the self-seat IP address “SIP26” is obtained. Thereafter, a service start notification is sent to the IP telephone terminal 2 (IP11) with the extension number “extension 126” and the self-seat IP address “SIP26” (step A14).
[0051]
Upon receiving this service start notification, the IP telephone terminal 2 (IP11) is automatically connected peer-to-peer with its own IP telephone terminal 2 (SIP4) via the LAN 3. As a result, the personal information stored in the database unit 22 of the IP telephone terminal 2 (SIP4) at the user's seat can be downloaded while preventing leakage to the outside (step A15). As a result, an operating environment for using the IP telephone terminal 2 (IP11) as the own IP telephone terminal 2 (SIP4) can be constructed. After the download of the personal information is completed, the IP telephone terminal 2 (IP11) completes login (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 only the IP telephone terminal 2 (IP208) in which the user authentication number USR4 corresponding to the own IP telephone terminal 2 (SIP4) is registered in the database 12 as the own IP telephone terminal 2 (SIP4). I was able to use it. On the other hand, according to the manual login, even if the user uses any IP telephone terminal 2, the user can enter the user authentication number and password to make the IP telephone terminal 2 the own IP telephone terminal 2 (SIP4). Can be used as
[0053]
2. change Password
Next, a sequence for changing the password for the user authentication number 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 by the sequence shown in 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. Thereby, the password change request is notified from IP telephone terminal 2 (IP208) to IP-PBX1 (step B2).
[0055]
The IP-PBX 1 that has received the password change request transmits a user input request to the IP telephone terminal 2 (IP 208) (step B3). Upon receiving the user input request, IP telephone terminal 2 (IP208) displays a password change prompt (FIG. 12) on screen display unit 21 (step B4), and waits for user input. The user inputs his / her user authentication number “USR4” in the Login section of the password change prompt and the old password “PW4” in the Old Password section of the password change prompt from the input processing section 20 of the IP telephone terminal 2 (IP208) (step). B5). Since the password change is performed in the login state, the user authentication number has already been input (step A7 in FIG. 14), but the input is requested again when the password is changed.
[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 in the New Password portion of the password change prompt (step B5). This is to prevent a user's password setting error. As a result, a user input response with the user authentication number, the old password, and the new password (for two inputs) is returned to the IP-PBX 1 (step B6).
[0057]
The IP-PBX 1 that has received the user input response searches the data on the database 12 (FIG. 5) 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). As a result of the verification, if they do not match (NO in step B8), a screen display request (error: old password mismatch) is transmitted to the IP telephone terminal 2 (IP208) (step B9). The IP telephone terminal 2 (IP208) displays the message “error: old password mismatch” on the screen display unit 21 (step 8B15).
[0058]
Here, since the collation results match (YES in step B8), collation of the new password “NP4” input and transmitted twice is performed. 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 (IP208) displays the message “Error: New password mismatch” on the screen display unit 21 (step 8 B15).
[0059]
Here, since the collation results match (YES in step B11), the password in the column corresponding to the user authentication number “USR4” in the data on the database 12 (FIG. 5) is updated from “PW4” to “NP4” (step B13). When the password is updated, the data on the database 12 (FIG. 5) becomes as shown in FIG.
[0060]
Thereafter, the IP-PBX 1 transmits a screen display request (normal: password change completion) to the IP telephone terminal 2 (IP 208) (step B13). When the IP telephone terminal 2 (IP208) receives the screen display request, the message “normal: password change complete” is displayed on the screen display unit 21 (step B15), and the password change process is terminated.
[0061]
3. Changing the login mode
Next, a sequence for changing the login mode for the user authentication number 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 the IP telephone terminal 2 (IP11) is logged in by 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 with the IP address “IP11” is notified from the IP telephone terminal 2 (IP11) to the IP-PBX1 (step C2).
[0063]
The IP-PBX 1 that has received the login mode change request searches for the received IP address “IP11” in the data on the database 12 (FIG. 5) (step C3). As a result of the search, since IP11 cannot be detected in this operation example (NO in step C4), the current login mode is determined to be the manual login mode. If IP11 exists (YES in step C4), the current login mode is the automatic login mode.
[0064]
After the current login mode is determined (here, the manual login mode), the IP-PBX 1 notifies the IP telephone terminal 2 (IP11) of a user input request with 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). “Self” indicating the manual login mode, which is the current login mode, is displayed in the Login Mode portion of the login mode change prompt (FIG. 13), and the apparatus waits for user input. The user selects “Self” or “Auto” (“Auto” in this operation example) in the New Mode portion of the login mode change prompt (FIG. 13) from the input processing portion 20 of the IP telephone terminal 2 (IP11). To enter a new login mode (step C9).
[0065]
As a result, a user input response accompanied by 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 login mode is the manual login mode (NO in step C11), a search is performed from the data on the database 12 (FIG. 5) using the user authentication number as a key, and the IP address in the corresponding column is deleted (step C12). . Note that 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) is as shown in FIG.
[0067]
Thereafter, the IP-PBX 1 transmits a screen display request (login mode change completion) to the IP telephone terminal 2 (IP11) (step C14). The IP telephone terminal 2 (IP11) that has received the screen display request displays the message “login mode change completion” on the screen display unit 21 (step C14), and ends the login mode change process.
[0068]
4). Logout
Finally, a sequence for logging out the IP telephone terminal 2 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 by the sequence shown in 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-PBX1 (step D2).
[0070]
The IP-PBX 1 that has received the logout request deletes the IP address “IP67” 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, the self-seat IP address corresponding to the user authentication number USR1 is searched in the data on the database 12 (FIG. 6) to obtain the self-seat IP address “SIP1” (step D4). Note that 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 its own IP address “SIP1” and a login prompt (step D5). The IP telephone terminal 2 (IP67) that has received the user input request makes a peer-to-peer connection with its own IP telephone terminal 2 (SIP1), so that the IP telephone terminal 2 (IP67) The personal information is uploaded to) (step D6). This updates the personal information stored in the self-seat IP telephone terminal 2 (SIP1) with the added, modified, or deleted personal information obtained during login.
[0072]
After the uploading 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 a user authentication number and password input waiting state (= logout state) is entered. (Step D8).
[0073]
As described above, when the user logs in to the IP telephone terminal 2 by using the arbitrary IP telephone terminal 2 in an arbitrary place and entering the user authentication number and password dedicated to the user, The personal information customized from the IP telephone terminal is automatically downloaded, and the IP telephone terminal 2 and the personal information can be used as if they were at their seats.
[0074]
【The invention's effect】
The first effect of the present invention is that even if it is an arbitrary IP telephone terminal in an arbitrary place, the personal database set in the own IP telephone terminal can be used as it is. This means that the IP telephone terminal can be used in a work environment similar to that of being at his / her seat at an arbitrary place.
[0075]
In addition, the second effect is that there are two types of IP telephone terminal login methods, a manual login mode and an automatic login mode, so that it can be used as a fixed terminal like the conventional PBX (automatic login mode) A service designed for the convenience of the user by providing two usage methods (manual login mode) in which a user can make a call using an extension number of his / her seat at any IP telephone terminal in an arbitrary location. It will be able to provide.
[0076]
Furthermore, the third effect is that each user has a dedicated user authentication number and password for the IP telephone terminal, and the 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 occurred when using the own IP terminal.
