The above and other objects and various advantages of the present invention will become more apparent from the preferred embodiments of the invention described below with reference to the accompanying drawings by those skilled in the art.

The configuration of the present invention is an ISDN line control unit 102 for transmitting / receiving an ISDN call, and processing a received ISDN call to connect with a corresponding called party, and when the call is received as an ISDN subscriber, a digital call for incoming processing to the ISDN subscriber. A control unit 104 and a number translation unit 106 for translating the numbers in response to the command of the digital call control unit 104.

Hereinafter, with reference to the accompanying drawings, it will be described in detail a preferred embodiment of the present invention.

First, referring to FIG. 1, FIG. 1 illustrates a block diagram of an ISDN switch suitable for displaying own terminal number in accordance with the present invention. The ISDN line controller 102 is provided from an ISDN subscriber when a call of ISDN subscribers is input. Send an information message such as setup message, digit information and device number, call connection request, call termination request, etc. to connect the ISDN call to an ISDN call or to another subscriber, and the ISDN call under the control of the digital call controller 104. To exit.

Then, the digital call controller 104 requests the number information of the service requesting device and transmits the received subscriber's number information to the terminal to display the information received from the ISDN line controller 102 received by the terminal.

The digital call controller 104 receives the information received from the ISDN line controller 102 and requests the number translation unit 106 to translate the number.

The number translation unit 106 determines the received number translation information to determine whether the service request or a connection request to the called subscriber requesting the service, and executes the corresponding service.

If it is determined in the above-described step that the connection request from the subscriber is determined to be a directory number display service, the directory number information of the corresponding calling party number translated to the calling party requesting the service is transmitted through the ISDN line control unit 102.

The number translator 106 receives the call request signal from the originating subscriber, translates the number of the originating subscriber and the number digitized by the originating subscriber, and transmits the number to the digital call controller 104, thereby transmitting the digital call controller 104. Determine whether to connect with the called subscriber, to execute the service, or to output an error message to the subscriber who requested the service.

Referring to FIG. 2, the steps of displaying the own terminal number in the ISDN exchange are described. When the ISDN subscriber inputs a command for displaying the own terminal number through the ISDN-type exchange, the ISDN exchange is inputted from an arbitrary subscriber. Receive the digit (step 202).

The ISDN line control unit 102 of the ISDN exchange receives the digits input from the digital subscriber, transmits the digits to the digital call control unit 104, and the digital call control unit 104 sets up the request of the originating subscriber.

The digital call controller 104 of the exchange analyzes the received digits to determine whether the method of transmitting the call is the Enbloc method (step 206).

The Enbloc method is a method of transmitting a series of stored numbers to an exchange at the same time by entering a set number of keys stored in the terminal when the subscriber enters a number. In this case, in the mobile communication telephone, the SND (sand) key is a key for simultaneously transmitting the stored number to the exchange.

As a result of the determination in step 206, when the Enbloc method is inputted with a special code to output its directory number in the setup message, the digital call control unit 104 converts the digit information from the ISDN subscriber to the digit number. 106 to translate the number (step 208).

The digital call controller 104 receives the number translation result from the number translation unit 106 and determines whether or not a preset special code is inputted to output the directory number to the number entered as the number translation result (step 210).

In the case where a predetermined special code for determining the output of the directory number is input in step 210, the process proceeds to step 228. In the case where the predetermined special code for outputting the directory number is determined in step 210, the preset special code is input. If not, it is determined whether its own terminal number is input (step 212).

If it is determined in step 212 that its terminal number is input, the flow proceeds to step 228. If it is determined in step 212 that it is determined that the terminal number is not input, it is determined that a digit displaying the own terminal number is input. If the number entered is displayed by sending a message informing that there is an error, or the announcement is broadcast, or if the corresponding number is the number of the called party, the call is connected to the number (step). 214).

If it is determined in step 206 that it is not the Enbloc method, the digital call control unit 104 processes the overlap method because it is an overlapping transmission type telephone.

The digital call controller 104 receives the digit number information received one by one from the subscriber who requested the service by the ISDN line controller 102 at a predetermined interval (step 216).

In this case, the overlapping method is an MFC telephone that we commonly use as a subscriber inputs a number, and the inputted number is transmitted to the exchange as soon as a signal is input.

The digital call control unit 104 transmits the digit number information to the number translation unit 106 to request number translation (step 218).

In operation 220, it is determined whether a preset special code for outputting own terminal number is input to the input number.

If the predetermined special code for outputting the directory number determined by the subscriber is input from the subscriber, the process proceeds to step 228. If the predetermined special code for outputting the directory number is not inputted, the control proceeds to step 228. If it is, it is determined whether its own terminal number is input (step 222).

If it is determined in step 222 that its own terminal number has been entered, the process proceeds to step 228. If it is determined in step 222 that it is determined that its own terminal number is not entered, the unsigned digit number is the subscriber described above. It is determined whether it has been input from (step 224).

If it is determined in step 224 that the unprocessed digit number is input from the subscriber described above, the process loops back to step 216 and receives input information such as digit information from the ISDN line control unit 102 to receive the input digit. Receive.

If it is determined in step 224 that an unprocessed digit number has not been entered, a message indicating that there is an error in the entered number is displayed to the subscriber, or an announcement of an error is sent or the called party requested by the subscriber is called. (Step 226).

If it is determined in step 210, 212, 220, 222 that the predetermined special code or its own terminal number for requesting its own directory number has been input, the subscriber's own phone number display information is sent to the terminal connected to the subscriber. The subscriber's own terminal number is displayed on the display device connected to the terminal (step 228).

A confirmation tone such as a message or tone indicating that the service has been successfully completed is transmitted so that the subscriber can confirm the service success (step 230).

For example, if it is determined by the digital call control unit 104 of the exchange and determined by the Enbloc method, and the special code for displaying the number of its terminal to the Enbloc type phone is set to * 88 *, the subscriber inputs * 88 *. When received by the setup message, the digital call control unit 104 receives the number translated number and determines its own terminal number as a special code for displaying.

Assuming that the telephone number of the subscriber who requested the service is ″ 252-200 ″, a message ″ My DN = 252100 ″ is output on the display panel of the subscriber terminal with a confirmation tone.

In the Enbloc method, another embodiment of the present invention, if a user inputs a number instead of a special code, ″ 252100 ″, and transmits it through a setup message, if it is determined to be the same value as the own terminal number obtained by translating the number, the calling subscriber Connect a confirmation tone to the subscriber's terminal with the output of ″ My DN = 252100 ″ on the display panel of the terminal.

Further, in another embodiment, if a special code for judging by the digital call control unit 104 of the exchange and determined as an overlap method and displaying a terminal number of the terminal with the overlap type phone is set to * 88 *, the subscriber is * 88. When each signal is transmitted to the digital call controller 104 through the ISDN line controller 102, the digital call controller 104 transmits the received special code to the number translation unit 106. Receive the translated special code and determine the own terminal number of the subscriber who applied for service as a special code for display.

Assuming that the telephone number of the subscriber who requested the service is ″ 252-200 ″, a message ″ My DN = 252100 ″ is output on the display panel of the subscriber terminal with a confirmation tone.

According to another embodiment of the overlap method, when a user transmits his or her own number instead of a special code, ″ 252-100 ″ is input, his terminal number obtained by translating the number is the same as his own terminal number. If it is determined, a confirmation tone is connected to the subscriber terminal with the output of the message ″ My DN = 252100 ″ on the display panel of the calling subscriber terminal.

In this case, when the subscriber inputs a number, the MFC phone that we commonly use is a method in which a number inputted like a general telephone is transmitted to an exchange as soon as a signal is input.

As an example, if a special code for displaying a number of its own terminal is set to * 88 * using an overlapped telephone, the digital call controller 104 of the switchboard determines that it is an overlapped method. If the own terminal number is ″ 252100 ″ and the special code for displaying his own terminal number is registered as * 88 *, if the subscriber enters ″ * 88 * ″ consecutively after setup, the number is translated and When it is confirmed that the code is a special code for displaying the own terminal number of the terminal, the message ″ My DN = 252100 ″ is output on the display panel of the subscriber station with a confirmation tone.

Alternatively, when 252100 is dialed continuously, if the own terminal number obtained by translating the number is the same value as the own own terminal number, a confirmation tone is outputted along with the output of ″ My DN = 252100 ″ on the display panel of the calling subscriber station. Connect

As described above, the present invention has the effect of verifying its own telephone number through a display panel connected to a telephone in an ISDN serviceable local or private exchange, thereby providing an improved service to digital subscribers.

The principles of the invention have been described above in connection with specific devices, which are described by way of example only, and are not limited to the spirit of the invention as described in the appended claims.
