JPS61169060A - Display system of caller position information - Google Patents

Abstract

PURPOSE:To recognize properly the position and the location of a caller by displaying the position information of the caller to a called party in talking connection. CONSTITUTION:When a caller A hooks off a handset, a central controller 3 connects the caller A to a register 2. When the caller A dials the number of the called party B next, the controller 3 starts a main storage device 4 and transfers the caller number and the position information of the caller stored in the device 4 to a display control circuit 5. A call signal is sent to the called party B as shown in broken lines II and a call tone is sent to the caller A as shown in broken lines III. When the called party B responds to the signal, the controller 3 connects the caller A and the called party B as shown in broken lines IV. The circuit 5 drives a display device 6 installed at the caller party B to display the caller number and the position information to the device 6 as shown in broken lines V. Thus, the called party B confirms visually the position and the location of the caller.

Description

DETAILED DESCRIPTION OF THE INVENTION <Field of Industrial Application> The present invention relates to a telephone exchange, and more particularly to a calling party location information display method for displaying location information of a calling party to a called party.

<Prior Art> Conventionally, in the connection of electronic switching equipment, there has been a display method that automatically displays the calling party's number to a specific called party. In the event of an emergency call such as a fire or traffic accident, it is only after the calling party and the called party are connected that location information such as the location of the calling party can be obtained. There was a problem in that it took time to obtain and confirm location information.

Problems to be Solved> The present invention is intended to solve the above problems, and provides a method for displaying caller location information that can directly display the caller's location information to the called party when a call is connected. It is about providing.

<Means for Solving the Problems> In order to solve the above problems, the configuration of the calling party location information system according to the present invention includes a means for storing the location information of the subscriber and a means for receiving the call from the subscriber in the telephone exchange. In this case, the calling party's location information is read out from the storage means, and the caller's location information is displayed to the called party.

<Example> Next, one embodiment of the present invention will be briefly described with reference to the drawings.

FIG. 1 is a relay system diagram showing an embodiment of a caller location information display system according to the present invention.

FIG. 2 is a block diagram showing main parts in the same embodiment.

FIG. 3 is a format diagram showing caller information stored in the main storage device in the same embodiment.

In the figure, 1 is a switch (SW), and A and B are subscribers connected to this switch 1. In this embodiment, A is the calling party and B is the called party. 2 is a register, 3 is a central control unit (CC), and 4 is a central control unit (MEM). A display device control circuit (DISPC) 5 is connected to the central control device 3, and a display device 6 attached to subscriber B is connected to this display device control circuit 5.

The main storage device 4 stores in advance the calling party number a1 of the calling party A and its location information (installation location name, etc.) a2. As shown in FIG. 2, the display device control circuit 5 includes a memory readout section 5a that reads out caller A information from the main storage device ft4 via the central control device 3, and a memory readout section 5a that reads out caller A information from the main storage device ft4 via the central control device 3. Based on the buffer circuit 5b that accumulates and transfers the accumulated information to the display drive device 5c, and the caller A information transferred from this, the display device 6 is driven to transfer the caller A information.
It is composed of a display device driving device 5c.

Next, to explain the operation of the above embodiment, first, caller A
When the caller A picks up the handset for the purpose of making a call, the central control unit 3 connects the caller A to the register 2, as shown by the dashed line in FIG. 1, in a manner similar to a conventional switched connection. Next, when calling party A dials called party B for the purpose of an emergency call, called party B's number is registered in the emergency call answering phone and is pre-registered.
The central control device 3 activates the main storage device 4, transfers the calling number a1 and location information a2 of the calling party A stored therein to the display device control circuit 5, and also sends a calling signal which is a normal connection. At the same time as the ringing tone is sent to the called party B as shown by the broken line ■ in FIG. 1, a ringing tone is sent to the calling party A as shown by the broken line ■ in FIG. Here, when the called party B answers, the central control device 3 connects the calling party A and the called party B as shown by the broken line ■ in FIG. 1, but at the same time, The display device control circuit 5 drives the display device 6 installed at the place of the called party B, and displays the calling party number a1 and location information a2 on the display device 6, as shown by ay in FIG. .

This allows the called party B to visually confirm the location of the calling party A.

<Effects of the Invention> As explained above, according to the caller location information display method according to the present invention, by displaying not only the caller's number information but also the location information, the caller's location can be displayed. This has the effect of being able to accurately recognize a location.
