Description

Description: TECHNICAL FIELD The present invention relates to a telephone exchange system, and is particularly suitable for registering various services from a terminal other than the terminal device to the terminal device and for switching connection of a call via the terminal device. The present invention relates to a method for controlling an identification number registered for each terminal device.

[Conventional technology]

In a conventional telephone exchange system, a variable call forwarding, a message service, etc. are registered in the own terminal device, and an incoming call from another terminal device to the own terminal device is diverted to the transfer destination terminal device or the message is transmitted. Message to the caller.

[Problems to be solved by the invention]

In such a system, when changing or canceling the service registered in the own terminal device, it is necessary to return to the user's seat and operate with the own terminal device. In such a case, when the seat is far away or outside the company, the user must once return to his / her own seat or the company, which is time-consuming, and has the drawback that the service cannot be easily changed or canceled. Further, not only the change or deletion of the service, but also the case where the user wants to newly register the service in the terminal device at his / her seat from another seat, he / she must return to his / her own seat, which has the same inconvenience. Another drawback is that even when a message or the like is registered in the terminal device from another terminal, the registered contents (so-called registered service contents) cannot be known until the user returns to the terminal. Also, for the variable abbreviated dialing that can be registered and transmitted for each terminal device, the special abbreviated number + the terminal number of the abbreviated terminal + the variable short path, in order to perform the variable abbreviated dialing registered at the terminal device at the own seat from the terminal device at the other seat. There is also a function that allows a call to be made by dialing a number. However, in this case, there is a disadvantage that a call can be made from anyone other than the user's own seat and calling from other seats cannot be restricted.

SUMMARY OF THE INVENTION It is an object of the present invention to identify various service registration states of a terminal device of another seat or a terminal device of the own seat via a line trunk and to display, change, delete, or register a new service of a terminal device without returning to a seat. It is to provide a possible and efficient switching connection.

[Means for solving the problem]

An object of the present invention is to store a terminal device identification number (corresponding to a personal identification number registered individually for each terminal device) in pair with a terminal number (corresponding to an extension number registered for each terminal device) for each terminal device in the telephone exchange system. If the caller terminal device identification number dialed by the caller is compared with the terminal device identification number registered in the called terminal device and they match, the service contents registered in the called terminal device and the service being registered are transmitted to the terminal device of the caller. This can be achieved by a configuration in which information is virtually transferred.

[Action]

The terminal line replacement method using the terminal device identification number of the present invention can be performed by simply dialing the terminal device identification number of the own seat using the terminal device of the other seat or the office line trunk, and the contents being registered or registered with the terminal device of the own seat. Can be changed and released easily,
In addition, since it can be realized only when the identification number registered by dialing matches the identification number, only a person who knows the terminal device identification number at his / her seat can operate.

〔Example〕

FIG. 1 is a block diagram showing connection control for explaining an embodiment according to the present invention. First, the terminal device 1 in the other seat
An example of an operation method for virtually replacing the terminal device 1-2 in the user's seat using the device 1 will be described with reference to FIG. The terminal device 1-1 raises the handset and listens for a dial tone.
The terminal device 1-1 uses * as the terminal device identification number start code.
Dial 2-2, and then dial the terminal device identification number (personal identification number) of the called side (own seat). 2-3 # is dialed as the terminal device identification number end code. 2-
4. At this point, the central processing unit CPU1-7 temporarily stores the received called terminal device identification number in the main memory MM1-6.
Next, the terminal device 1-1 sets the terminal number (extension number) 1-
If you dial 2, 2-5, CPU1-7 receives first and MM1
The terminal device identification number stored in -6 is already stored in the terminal device 1.
-2 compares the own terminal apparatus identification number registered in MM1-6 with 2-6, and if they do not match, sends out a tone that cannot be virtually replaced on the terminal line. If they match, the caller's terminal line 1-
1 is virtually replaced under the condition of the called terminal line 1-2. 2-7 Therefore, at this point, all the service information that the called party's terminal line 1-2 is registering or being registered is
The information is virtually transferred to the caller's terminal line 1-1, and a tone is transmitted to the caller's terminal device.
D8-4 display, LCD8-3 display, etc. are performed.

Next, the terminal device 1 at the user's seat via the office line trunk COT1-3
An example of an operation method for virtually replacing -2 will be described with reference to FIG. A response (revers) is returned to the DID (direct in-dial) incoming call 3-1 of the office trunk COT1-3, 3-2, and a PBREC (PB receiver) 1-5 is connected 3-3, and the office trunk COT1. -3 is received. First, * is received as the terminal device identification number start code,
4. Subsequently, the terminal identification number of the called terminal device 1-2 is received. 3-5, and # as the terminal device identification number end code
To receive. 3-6. At this time, the CPU 1-7 temporarily stores the received called terminal identification number in the MM 1-6. Next, when receiving the called terminal number 1-2, the CPU 3-7 receives the terminal identification number previously received and stored in the MM1-6, and the terminal 1-2 already recognizes the MM1-6. The terminal line COT1-3 is released by comparing with the own terminal device identification number registered in the terminal line 3-8. If they do not match, the terminal line cannot be virtually replaced. If they match, the caller's line 1-3 is replaced by the called party's terminal line 1-
Virtual replacement is performed under the condition of 2. 3-9. At this time, all the service information for which the terminal line of the individual is being registered or registered is transferred to the line 1-3 of the sender. In this case, since the calling line is a central office trunk, LED lamp display, LCD
Although it is not possible to display the characters, the method of notifying the contents of the service being registered or being registered by the audio device may be used in order to eliminate these, but this is not specified. In this manner, the service contents can be identified during registration or registration of the called terminal after replacement of the terminal line, even from a terminal device having no LED lamp or LCD display.

In this embodiment, the operation method of dialing * as the start code and # as the end code before and after the terminal device identification number has been described. However, it is sufficient that the terminal device identification number on the called side can be distinguished from the called terminal number. Therefore, the dial operation is not particularly limited.

Next, a specific description will be given of a terminal line replacement control method in a case where a terminal device at the own seat during the variable call forwarding registration is called from another terminal device and the variable call forwarding extension is changed. First, an operation method for registering the variable call forwarding with the multifunction telephone (extension number 200) at the seat will be described with reference to FIG. Raise the handset of the multi-function telephone 4-1 and listen to the dial tone and press the absent function key. 4-
2. After confirming the absence lamp ignition, dial the extension number 201 of the transfer destination. 4-3. If registration is OK, listen to the registration completion sound and lower the handset. 4-4. The multifunction telephone at the seat is in the process of registering a variable call forwarding, so that the absence lamp is lit and the handset is raised to hear the 4-5 service registration sound.

Next, referring to FIG. 5, a case will be described in which the multi-function telephone at the other seat accesses the multi-function telephone at the own seat. First, raise the handset, dial 5-1 after listening to the dial tone. 5-2,
Subsequently, the terminal device identification number of the user's seat, for example, 3524 is dialed. After dialing the 5-3 terminal device identification number end code #, dial the extension number 200 of the 5-4 own seat. 5-5. The central processing unit CPU1-7 stores the terminal device identification number 3524 registered in the main memory MM1-6 by the terminal device having the extension number 200 as shown in FIG. The terminal device identification number 3524 is compared, and if they match, as shown in FIG. 7, the variable call forwarding information X7-8 registered in the multifunction telephone having the extension number 200 itself is stored in the caller information area of the other seat. The information X is transferred to the call terminal service information save area. 7-5,
At this time, the information is transmitted to the caller during the service registration sound transmission and the absence lamp is ignited, and the terminal conditions at the seat are virtually replaced with the terminals at the other seat. Therefore, as shown in FIG. 5, in the multi-function telephone at the other seat, the absence key is depressed in order to change the forwarding destination and the extension number of the forwarding destination, for example 5-5.
Dial 202. 5-7, whereby the information X in the called terminal service information save area in the caller information area in FIG. 7 is changed to Y. 7-6. Then, after listening to the registration completion sound shown in FIG. 5, lower the handset 5-8. Then, the information Y stored in the called terminal service information save area of the caller shown in FIG. The information is transferred to the own terminal service information area in the information area 7-11, and the absence lamp of the called multi-function telephone is lit again based on this information. The called terminal service information save area in the caller information area is cleared by lowering the handset of the other terminal and returns to the original terminal line.

In the present embodiment, the terminal device identification number is described by four digits, but it is needless to say that it is not particularly required to be four digits.
Also, the method of returning to the actual terminal line after virtually replacing the terminal line of the other seat with the terminal line of the own seat is described in Descending the handset of the caller, but pressing or releasing another release key An operation of a code dial or the like or an automatic release after a lapse of a certain period of time can be considered, but no particular operation is specified.

In addition, although the registration method of the terminal device identification number is not particularly specified, a registration method by key operation from the terminal device or a registration format by an external input device is considered, and a particularly limited registration method is not specified.

〔The invention's effect〕

According to the present invention, as described in the embodiment, by simply dialing the terminal device identification number of the own seat by the terminal device of the other seat or the office line trunk, the content being registered or registered at the terminal device of the own seat can be displayed. It is highly effective because it can be easily changed and released, and can be operated and responded quickly.

In addition, the present invention can be realized only when the terminal device identification number is dialed and matches the registered identification number, so that the operation can be performed only by a person who knows the terminal device identification number of the user's seat, so that another person can easily use the terminal device identification number. Since the terminal information is not changed, it is also effective in information protection.
