The present invention relates to a method for displaying caller information in an electronic switchgear, and more particularly, to a method for displaying a caller's information to a called subscriber in a TIDX-1B (TDX_1B) telephone exchange. .

Conventionally, a malicious call tracking service is a service that an operator tracks a call to an operation terminal and provides it to a user. Using this service, a called party determines whether a call is made through a display device and determines whether to receive a call accordingly. Can't.

Accordingly, the present invention has been made to solve the above-described problems, and the caller in the TDX-1B electronic switchboard, which allows the called party to check the information of the calling party through the display device. The purpose is to provide a method of displaying information.

In order to achieve the above object, a caller information display method in an electronic switch according to a preferred embodiment of the present invention, the subscriber control processor located in the first shelf of the subscriber rack of the standard rack shape in the switch to display the caller information Adding a frequency shift modulation data generation function to a board used for the purpose; collecting caller information including caller name information by interworking with a name database system when a caller's call signal is received at the destination exchange; Characterized in that it comprises the step of displaying the caller information on the display means of the telephone of the called subscriber by sending the information of the called party to the telephone of the called subscriber by modulating the frequency shifter.

Hereinafter, with reference to the accompanying drawings will be described an embodiment of the present invention in more detail.

1 is a diagram showing the structure of the TDX-1B electronic switch system and the caller information display service data path applied to an embodiment of the present invention, in the TDX-1B system. Calling Identity Delivery service is implemented by FSK signal system and its system structure is as follows.

The OMP 10, a T-level processor system, manages and maintains all maintenance functions of the system. The SNP 12 controls the switch unit (SWCD), which is the main exchange device, and handles station number translation (routing decision) and some special services. In addition, the SLP 14 controls the subscriber unit in units of 1,024 lines and performs a maintenance function for the subscriber unit under the control of the OMP 10.

The DTLP 16 controls the relay line unit of a digital 480 line unit and performs a maintenance function for the relay line unit under the control of the OMP 10.

The OMP 10, SNP 12, SLP 14, and DTLP 16 are interconnected via a T-bus.

The ALCP 18, which is a B-level processor system, controls the subscriber module (ALC) 20 in units of 256 lines as a lower processor of the SLP 14, and the SSGP 22 is a PBID (Push) which is a digit receiving device of the subscriber circuit unit. Button Sender Receiver Interface Device (eg, USRD, TGD (Tone Generator Device)).

The subscriber module (ALC) 20, which is a device system, accepts an analog subscriber, and the TGD 24 provides various tones to the subscriber.

In the implementation of the caller information display function according to an embodiment of the present invention, the MLIB-B (Memory and Line Interface) of the conventional subscriber control processor (SSGP) 22 is implemented without first implementing a new hardware shape in consideration of operability and economical efficiency. In addition to maintaining existing functions on the Board-B, it implements additional Frequency Shift Modulation (FSK) data generation and eight channels per MLIB-F (Memory and Line Interface Board-FSK) 26.

In addition, the MLIB-F 26 receives a command input from a common processor board (CPB-B) 28 to receive a frequency shift modulation (FSK) signal from a DSP chip. After the data is generated as PCM data, it is sent to the digital line concentrator device (DLCD) 30. The MLIB-F 26 implements a maintenance test function for a frequency shift keying (FSK) generation function.
That is, the MLIB-F 26 of the present invention not only performs communication of signals such as ring signals of the conventional MLIB-B, but also performs frequency shift braiding to match a format for transmitting and receiving caller information. That is, the MLIB-F 26 modulates the frequency shifter of the sender information received from the common processor board (CPB-B) and transmits the modulated sender information to the requested subscriber channel.

In addition, in order to perform the caller ID service, a service is provided using resources in the exchange, and the caller name service is an INAP protocol using the No. 7 network 32, which provides a service by interworking with the name database system 34. do.

On the other hand, in order to perform the sender information display service in the exchange to which the present invention is applied, it is possible to provide a caller information display service to the system by developing a MLIB-F board which adds a frequency shift modulation (FSK) data generation function to the existing MLIB-B. In addition, it can be implemented without interruption of call when adding function, and it uses half duplex method for frequency shift modulation (FSK) data maintenance function while taking advantage of operation advantages as it is.

In addition, by replacing and replacing the new MLIB-F board that implements the frequency shift modulation (FSK) function in the existing MLIB-B board, caller information display service is possible. In addition, the MLIB-B board can be used for maintenance of other B-level processors in the existing subscriber control processor (SSGP).

In addition, the switch resources can be serviced without using additional switch resources by using the sub-highway (SHW) No. 31 not used in the subscriber rack (SUBR).

Therefore, according to the caller information display method in the TDX-1B electronic switch in accordance with an embodiment of the present invention, if any caller makes a call to the desired recipient, the caller's call signal is called the call exchanger. Is sent to the destination exchange to which the called party subscribes.

The destination exchange then interworks with the name database system to collect the caller's information (i.e. telephone number or telephone number and name).

Thereafter, the called exchange sends the collected caller's information to the telephone of the called subscriber, so that the caller's information is displayed on the display means of the called subscriber's telephone.

The called party checks the displayed caller's phone number or phone number and name, and then receives the call.

FIG. 2 is a mounting diagram of a rack in which a frequency shifted modulation (FSK) data generation function employed in an embodiment of the present invention is implemented, and is located in a first shelf (Shelf 0) of a subscriber rack (SUBR) among standard rack shapes. The existing MLIB-B board used for (SSGP) is replaced by the MLIB-F board with the addition of new Frequency Shift Modulation (FSK) data generation.

Therefore, when the sender information display service function is applied to the electronic switching system, it is possible without relocating the rack or removing / mounting the backboard.

Figure 3 shows the position where the conventional MLIB-B and the new MLIB-F board is replaced, it is possible to conveniently remove / mount without interrupting the call in the system operating state.

According to the present invention as described above, it is provided to the analog subscribers of the public telecommunication network (PSTN) to provide basic services and additional services in the exchange, and in the medium to long term computer telephony integration (CTI) and server (server) It is an essential resource for providing various services in connection with

On the other hand, the present invention is not limited to the above-described embodiment, but can be modified and modified within the scope not departing from the gist of the present invention, such modifications and changes should be regarded as belonging to the following claims. will be.
