Abstract

PURPOSE:To recognize the state of a telephone set terminal efficiently by providing a database storing a data representing a current state of each telephone set terminal and reading the content of the database corresponding to a telephone set terminal on request when a service request comes from the telephone set terminal so as to inform it to the telephone set terminal on request. CONSTITUTION:When a service request is given to a system control section 5, the section 5 confirms it that a telephone set terminal on request 2 is available of the request and sends a signal representing the permission of the service request to the telephone set terminal 2. Then the operator of the terminal equipment 2 dials a telephone set terminal of service request destination, that is, a telephone set terminal number whose current state is desired to be recognized. When the request destination is a telephone set terminal 3 and its number is 001, the control section 5 retrieves a database 6 corresponding to the terminal equipment 3, reads the information and sends it to the terminal equipment 2. Thus, since the information representing the current state of the terminal equipment 3 is displayed onto a display device or the like provided to the terminal equipment 2, the operator resident at the terminal equipment 2 recognizes the state without calling the terminal equipment 3.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an exchange used in a telephone service system such as a PBX, and more particularly to a technique for recognizing the status of a telephone terminal on the other end without calling it.

0002

2. Description of the Related Art In recent years, as the services of electronic exchanges used in PBXs and the like have become more diversified, there has been a demand for more convenient services.

[0003] When a conventional telephone exchange receives a call request from a certain telephone terminal, it sends a calling signal to the called telephone terminal and controls the telephone terminal to conduct a telephone conversation. In such exchanges, even when the user simply wants to know the status of the other party, such as whether or not the other party is there, the user must call the calling party and talk to the other party. For this reason, even if the other party is very busy, the user has to use the telephone terminal to talk to the other party for less important requirements, which causes a great deal of inconvenience to the other party.

[0004] Furthermore, when it is desired to confirm whether or not a telephone with a certain signal exists, such as during maintenance, it is first necessary to press that number and try to call the other party. If a telephone terminal with that number exists, the user must talk to the other party at that terminal, causing trouble to the other party.

[0005]

[Problem to be Solved by the Invention] As described above, in conventional exchanges, it is necessary to call the other party and make a call to confirm the simple status of the other party, which is not very important. there were. Therefore, there was a problem in that it caused a great deal of trouble to the other party.

[0006] This invention has been made in order to solve the above-mentioned conventional problems, and its purpose is to call the requesting party's phone by checking the status of the terminal without calling the other party's telephone terminal. The purpose is to provide an exchange that can notify terminals.

[0007]

[Means for Solving the Problem] In order to achieve the above object, the present invention provides an exchange that is connected to a plurality of telephone terminals and controls communication between the telephone terminals, and that indicates the current state of each of the telephone terminals. A database that stores data, and when a service request is made from the telephone terminal, the contents of the database corresponding to the requested telephone terminal are read out and a service request is made without making a call to the requested telephone terminal. It is characterized by having a system control unit that notifies the telephone terminal.

[0008]

[Operation] With the configuration as described above, data indicating the current status of each telephone terminal is written into the database. Then, when a service request is made, the contents stored in the database corresponding to this telephone terminal are transmitted to the service requesting telephone terminal without making a call to the telephone terminal of the request destination.

[0009] Therefore, at the service requesting telephone terminal,
Data indicating the status of the request destination telephone terminal can be obtained without calling the telephone terminal.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing the configuration of a telephone service system including an electronic exchange 1 to which the present invention is applied.

In the figure, an electronic exchange 1 is connected to a plurality of telephone terminals (two telephone terminals 2 and 3 in the figure), controls calls between each telephone terminal, and is connected to a system control section 5. , has a database 6.

The database 6 is provided for each telephone terminal, and sequentially exchanges data with the corresponding telephone terminal to obtain data indicating the status of the telephone terminal, such as the telephone number and whether or not the telephone is free. It writes and stores data such as whether or not incoming calls have been rejected, and the time of last use.

[0013] When the system control unit 5 receives a call request from a telephone terminal, it makes a call to the called destination telephone terminal, and also sends a request to simply know the status of the other party's terminal without requiring a call. When there is a service request (hereinafter referred to as a service request), the contents stored in the database corresponding to the other party's terminal are read out and transmitted to the service requesting telephone terminal.

Next, the operation of this embodiment will be explained with reference to the sequence diagram shown in FIG.

Normally, among a plurality of telephone terminals, those that are capable of making a service request and those that are not capable of making a service request are divided, and if the service request key is pressed on the telephone terminal 2 that is capable of making a service request, A service request is transmitted to the electronic exchange 1 (step ST1).

When the system control unit 5 receives this service request, it confirms that the requesting telephone terminal 2 is capable of requesting the service, and transmits a signal to the telephone terminal 2 indicating that the service request is permitted. (Step ST2).

Next, at the telephone terminal 2, the operator dials the telephone terminal number of the service request destination, that is, the telephone terminal number whose current status is desired to be known (step ST3). Now, the destination of this request is telephone terminal 3, and its number is "2".
001'', the system control unit 5 searches the database 6 corresponding to this telephone terminal 3 (step S
T4), this information is read and transmitted to the telephone terminal 2 (step ST5). As a result, information indicating the current status of the telephone terminal 3 is displayed on the display provided on the telephone terminal 2, so that the operator on the telephone terminal 2 side can know the status without calling the telephone terminal 3. This is possible.

Now, for example, telephone terminal 3 (telephone terminal number "
2001") is in the idle state, incoming calls are being rejected, and the last time of use was 1:15 p.m., the display is displayed on the telephone terminal 2 as shown in Display Example 7 in FIG. 1.

[0019]The operator then looks at this display and says things like, ``Currently, telephone terminal 3 is rejecting calls, so it must be in a meeting right now,'' or ``The last time it was used was 1:15 p.m., so someone is still in the room.'' It is possible to infer the state of the other party, such as "he is probably in the area."

[0020] Also, from the telephone terminal 2, the telephone terminal number "2"
002'' exists, a service request is made using the same procedure as in the above example. As a result, if it is confirmed that it does not exist, the display of the telephone terminal 2 is displayed as shown in Display Example 8 of FIG. This allows the operator to confirm that the telephone terminal 4 with the number "2002" does not exist without making a call.

In this way, in this embodiment, a database for each telephone terminal is provided in the electronic exchange 1, and the status of the telephone terminal is stored in this database. and,
When a service request is made, the stored contents are transmitted to the service requesting telephone terminal and the operator is notified.

[0022] Therefore, it becomes possible to know the status of the telephone terminal to which the service is requested without calling it. As a result, the problem of bothering the other party simply because one wants to know the other party's status is eliminated.

In this embodiment, the electronic exchange 1 is provided with a database, but each telephone terminal may have a database.

[0024]

As described above, according to the present invention, the status of the other party's terminal can be known without making a call to the other party's terminal. Therefore, it is possible to eliminate the problem of having to bother the other party when the user wants to know a simple status of the other party's terminal.
