CONSTITUTION:When dialed numeral information is received in an exchange, the dial number is informed (c) to an external computer, the external computer receiving the number retrieves (d) a connection destination, allows the exchange to make a connection request to the connection destination (e), the exchange receiving the request makes connection processing (f), the external computer implements retrieval processing of display information corresponding to the dial (g), makes a display request of a called terminal equipment to the exchange (h), and the exchange makes display control to the called terminal equipment according to a display request from the external computer (i).

Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a private branch exchange that connects a calling terminal and a called terminal, and more particularly to a call display control method for displaying display information on a called terminal.

0002

2. Description of the Related Art Generally, in a private electronic branch exchange, when a call is made by dialing from a calling terminal, the calling terminal and the corresponding receiving terminal are connected by a stored program in an external computer. Conventionally, private electronic branch exchanges have adopted an incoming call display control method that unconditionally displays the extension number of the caller on the incoming terminal.

0003

[Problems to be Solved by the Invention] However, this conventional incoming call display method only displays the extension number of the caller, and there is no method for displaying various information corresponding to the dialed number. In the case of reception work, there is a problem in that it is difficult to confirm various information such as what the caller is for and who is calling before answering and talking to the caller.

The present invention has been made in view of the above problems, and is an incoming call display method that can display various types of information corresponding to dialed numbers and can quickly confirm information. The purpose is to provide.

[0005]

[Means for Solving the Problems] In order to achieve the above object, the incoming call display control method of the present invention provides a method for controlling dialed calls from a calling terminal in an exchange that connects a calling terminal and a receiving terminal by a storage program of an external computer. a notification means for notifying a number to an external computer; a connection means for connecting to a receiving terminal accommodated in the exchange corresponding to the dialed number based on a connection request from the notified external computer; The apparatus is configured to include display means for displaying display information corresponding to a number dialed to the receiving terminal on the receiving terminal based on a display request from the computer.

[0006] If necessary, the display means is configured to display display information corresponding to the dialed number retrieved from the database by the external computer.

[0007]

[Operation] According to the incoming call display control method having the above configuration,
When the exchange receives a dialed call from a calling terminal,
The dialed number is notified to the external computer, and when a connection request is received from the external computer, the external computer connects to the incoming terminal accommodated in the exchange according to the dialed number, and displays the information from the external computer. When a request is made, display information corresponding to the number dialed to the receiving terminal is displayed on the connected terminal.

[0008]

Embodiments Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 and 2 are a relay system diagram and a processing sequence diagram, respectively, to which an embodiment of the present invention is applied. In FIG. 1, the exchange includes a time division switch 6 and a control CPU.
3, and accommodates an extension terminal (STA-A) 1 and an extension terminal (STA-B) 2. In addition, the control CP
U3 is functionally coupled to an external computer 5 via an information communication path 4. A database 7 stores connection destinations and predetermined display information for each connection destination.

The control CPU 3 includes notification means for notifying the external computer 5 of the number dialed from the calling terminal;
a connecting means for connecting a calling terminal and a receiving terminal corresponding to a dialed number based on a connection request from the external computer 5, which will be described later; and display means for displaying display information corresponding to the assigned number.

[0010] When the external computer 3 receives the notification from the notification means, it has a function of searching the database 7 for the receiving terminal corresponding to the dialed number and sending a connection request to connect to the receiving terminal. It also has a function of searching the database 7 for display information corresponding to the dialed number and sending out a display request to display the display information.

Next, an example of operation will be explained according to FIG. When you make a call from STA-A1 (a) and dial (b)
), after receiving the dial, the control CPU 3 sends the STA-A
1 notifies the external computer 5 of the dialed number via the information communication path 4 (c).

The external computer 5 searches the database 7 for a connection destination corresponding to the dialed number (d
), and when it is determined that it is STA-B2 from the connection destination, STA-B2 is sent to the exchange.
A connection request (e) is made via the information communication path 4 to connect TA-A1 and STA-B2. Based on this request, the control CPU 3 performs connection processing (f) between STA-A1 and STA-B2.

The external computer 5 also searches the database 7 for display information corresponding to the dialed number (g), and sends a display request (h) to the STA-B2 to display the information. 4 to the exchange. Based on this request, the control CPU 3
Display control (i) is performed for 2.

[0014]

[Effects of the Invention] As explained above, according to the incoming call display control method of the present invention, various information corresponding to the number dialed at the time of incoming call can be displayed on the incoming terminal, so that telephone service can be quickly responded to. There is an effect that it can be done.
