Abstract

PURPOSE:To specify the caller at the called side by using an ID card reader to read identification information of a caller registered in advance on an ID card and displaying the caller ID information to the called party extension telephone set. CONSTITUTION:A caller at first allows an ID card reader 8 added to an exten sion telephone set 7 to read ID information through an ID card 9. Then the caller hooks off the telephone set 7 and dials an exclusive network access special number and a called party extension number. A caller station exchange 13 stores and analyzes the dial number from the telephone set 7 and adds the ID information read previously to a common line signal call message (IAM) in the case of dialing to a private line network and sends the resulting signal. The caller message is sent to a called exchange via a relay station exchange 14. The called own station extension telephone set 10 is discriminated from the received call message by the exchange 15, the telephone set 16 is called by a ringer and the caller ID information added to the call message is displayed on the telephone set 16 simultaneously.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a common line signaling system for electronic private exchanges and exchanges.
In particular, the present invention relates to a calling party information display method for displaying calling party information on a called party's extension telephone.

[Conventional technology]

When calling party information is displayed on an extension telephone using the conventional common line signaling system, the extension number of the calling party's extension telephone is displayed.

[Problem to be solved by the invention]

In the conventional caller information display method described above, the extension number of the calling party's extension telephone is displayed on the called party. If you move within the country and make a call from the nearest extension telephone, there is a drawback that the caller cannot be identified on the receiving side.

[Means to solve the problem]

The caller information display method of the present invention is such that in a private branch exchange system having a dedicated line network connection function using a common line signaling system, before a call is made from an extension telephone equipped with an ID card reader to a dedicated line network, a first means for reading identification information of a caller pre-registered in an ID card by the ID card reading device attached to the ID card; and a first means for transmitting a calling message from a common line signal transmitting/receiving device of a calling station when making a call on a dedicated line network. a second means for adding and transmitting the identification information read by the first means; and a common channel signal transmitting/receiving device receiving the outgoing message from the originating station at the receiving station and adding it to the outgoing message. and third means for reading out the identification information and displaying it on the called extension telephone that answered the call, so that even if the call is made from any extension telephone within the leased line network, the caller can be identified on the called party. It is possible.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 shows the configuration of an apparatus according to an embodiment of the present invention.

In this embodiment, the common line signal is transmitted from the common signal line trunk 5 via the exchange switch 2 to the common line signal transmitting/receiving device 3.
The common line signal transmitting/receiving device 3 transmits the common line signal and transmits the received common line signal to the exchange CPU 1 according to instructions from the exchange control unit (CPU) 1.

On the other hand, the identification (ID) registered in advance in the ID card 9
The information is read by an ID card reader 8 connected to the extension telephone 7, and the ID information is stored in the internal memory of the exchange CPUI via the digital line circuit 6. Note that 4 is a communication line trunk.

FIG. 2 shows an example of the control procedure in the same embodiment.
In the figure, 13 is an originating exchange, 14 is a relay exchange, and 15 is a terminating exchange. First, the caller swipes the ID card 9 through the ID card reader 8 attached to the extension telephone 7 to read the ID information (■). As the ID information, for example, member number 9 and name (alphabet notation) are registered in advance. Next, the calling party takes the extension telephone 7 off-hook (■) and dials the dedicated line network access special number and the called party's extension number (■).

The originating exchange 13 stores and analyzes the dialed digits from the extension telephone 7, and when making a call to a dedicated line network, adds the previously read ID information to the common line signal calling message (IAM). Transmit (■) 0 The calling message is sent to the terminating exchange 5 via the relay exchange 14 (■) 0 The terminating exchange 15 transmits the received calling message (IAM) to the called local extension line. determining the telephone 16;
If the extension telephone 16 is empty, the extension telephone 16 is ringed, and at the same time, the caller ID information added to the calling message (IAM) is displayed on the extension telephone 16 (■). At this time, the destination exchange 15 sends a common line signal calling message (ACM) to the dedicated line network.
(■), and the calling message (ACM) is sent to the originating exchange 13 via the relay exchange 14 (
■) Thereafter, when the called extension telephone 16 responds off-hook (■), a common line signal response message (
ANC) is sent to the originating exchange 1 via the relay exchange 14.
3 ([Phase], ■), and from now on, extension telephone 10
A call is in progress between the user and the extension telephone 16 (@).

〔Effect of the invention〕

As explained above, according to the present invention, by displaying caller ID information on the called party's extension telephone, it is possible to display caller ID information on the called party's extension telephone. Even when the user moves and makes a call from the nearest extension telephone, the caller can be identified on the receiving side.

Claims (1)

[Claims] In a private branch exchange system having a leased line network connection function using a common line signaling system, before a call is made from an extension telephone equipped with an ID card reader to the leased line network, the ID card reader attached to the extension telephone reads the ID card. a first means for reading the calling party's identification information registered in advance in the private line network; a second means for transmitting with identification information added; and a common line signal transmitting/receiving device receives the outgoing message from the originating station at the destination station, reads out the identification information added to the outgoing message, and responds to the incoming call. a third means for displaying on the called party's extension telephone; the calling party is characterized in that the calling party can be identified on the called party even if the call is made from any extension telephone within the dedicated line network; Information display method.
