The present invention relates to a method for controlling a call restriction function in an electronic exchange, and in particular, a subscriber having a call restriction function sends a specified specific code and number to the exchange to change and cancel the call restriction range and related number according to the call restriction function. Call restriction function that can be controlled directly through the phone relates to a call control function remote control method of the subscriber.

In general, the call restriction function is one of the service functions provided by the electronic exchange. When a calling subscriber having a call restriction function picks up a handset and dials an arbitrary called subscriber number, the call is restricted according to the area to which the called subscriber belongs. Here, if the area is classified into domestic, local, and long-distance international area, this will be explained.-The self-local area is the case where the originating and receiving subscribers belong to the same exchange, and-the local area is the originating and destination subscriber belonging to different exchanges. The charges for the charges are tolled up and down.-The out-of-area is when the originating and receiving subscribers belong to different exchanges and the charges for the call are detailed. It is a case where a national call is established.

Conventionally, a call restriction function has been performed only when a subscriber having a call restriction function changes or cancels a call restriction area and contacts the telephone company, and the exchange maintainer in the telephone station changes or cancels the function through the VDU. At this time, the maintenance officer inputs a function and a new call restricted area by using a VDU or changes or deletes an existing call restricted area according to a new request of a function, a change or cancellation of a call restricted function. When the result entered by the above operation was correct, the subscriber was to contact the subscriber to receive the service function. In other words, every time you change or cancel, you must contact, there was a problem to wait a long time until the change and cancellation.

Accordingly, an object of the present invention is to provide a method for changing and canceling a number by sending a specific code and number designated by the subscriber directly through the telephone to the exchange without passing through the telephone exchange operator in charge. .

Another object of the present invention is to provide a method for allowing a subscriber to change and cancel a call restriction service directly and freely and quickly receive the service.

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

1 is a system diagram applied to the present invention, wherein the call limiting function ST1 is connected to the first central processing apparatus 10 through the subscriber network 0, and the signal processing apparatus through the network matching device 30. 60 and the signal matching device 70 are connected to the first central processing device 10, and the first recording device or the second recording device is connected to the first central processing device through the network matching device 30. It becomes a basic configuration for the performance of the invention. Note that other system parts are omitted here.

2 is a flow chart according to the present invention, the first step of recognizing the hook-off state of the call limiting subscriber, receiving the digits and checking whether the corresponding digits have reached a predetermined number, and the digits entered in the first step. Checks the first instruction (″ * 55 ″) or not, when the number reaches the predetermined number, and waits for the next digit when the call restricting function possessing subscriber is checked in the second step. A third step of checking whether the received digit is 1 or 2, which is the third command after the reception, and a second command (″ # 55 ″) when the first command (″ * 55 ″) is not in the second step; The fourth step of checking whether or not the input restriction is 1 or 2 after checking and accepting the call restriction function subscriber and waiting for the next digit, and the digit received in steps 3 and 4 Not 1 or 2 And transmitting a negative right congestion, if the one or two wait for the next digit. When the next digit is received, the fifth step of checking whether the digit is the third instruction ″ * ″, and the fifth step sends ″ * ″ or runaway sound and ″ * ″, and various data for the function. Recording, and the sixth step of transmitting a confirmation tone.

3 is a subroutine of the process (2a) of FIG. 2 according to the present invention, and FIG. 4 is a subroutine of the process (2b) of FIG. 2 according to the present invention.

Therefore, specific embodiments of the present invention will be described in detail with reference to 1-4. When the subscriber ST1 with the call restriction function picks up the handset in the process (2a), the first central processing apparatus of FIG. 1 detects it through the subscriber network 0 of FIG. 60) The signal matching device 70 is connected through the network matching device 30, and the dialer is sent out from the signal processing device. The subscriber ST1 which has heard the dial tone sends a digit to the exchange by pressing a button on the telephone.

The digits sent by the subscriber ST1 are received in the process (2b) through the signaler a of FIG. 1, and the number of digits received in the process (2c) after recording the received digits in the buffer of the signal processor 60 Determines whether is "3". If three digits have not been reached, wait for the next digit again and, if three digits have been reached, analyze it in step (2d).

Analyzing the three digits (referred to as PREFIX) accepted in the above process and determining whether it is ″ * 55 ″ or ″ # 55 ″ in step (2d) (2e), if not, the process is processed accordingly. Are treated together.

In the case of ″ * 33 ″ in the above process, it is first determined whether the limited function is retained in (2 m). In the case of (2m), if there is no function, a congestion sound is sent out in the process of (2l) through the subscriber network of FIG. 1, and if there is a function, the next digit is received in the process of (2n) (2p). In the 2Q process, the received digit is judged as 1 or 2. If it is not 1 or 2, the alarm is issued by sending a runaway sound in (2l). If it is 1 or 2, the next digit is received through (2r) (2s). In the process (2t), if the digit is not ″ * ″, a congestion sound is sent and information is received. If ″ * ″, the digit received from the first recording device or the second recording device of FIG. 1 is transferred. Check in step (2u) if the digit received before ″ * ″ is ″ 1 ″. If it is ″ 1 ″, the call restriction function subscriber can perform the call up to the local area and related data is recorded in the process (2v).

If it is not ″ 1 ″ in the process 2u, and ″ 2 ″ in the process 2w, related data is recorded in the process 2x so that the call can be performed to the suburban area. When the recording is completed, in step 2y, a confirmation tone (degree, US, brush) is transmitted to the subscriber ST1 through the subscriber network to inform that the change is completed.

If the digit received in step (2d) is not "* 55" and is "# 55" in step (2e), it is determined whether the call restriction function holder is held in step (2f) as described above.

If the next digit is received through step (2g) (2h), if the corresponding digit is 1 or 2 in step (2i), if the next digit is received through step (2j) (2k), if it is not 1 or 2, (2l) In the process of sending a runaway sound through the subscriber network to warn.

Digit received through (2j) (2k) is judged in (2t ') process, and if it is ″ * ″, the digit received through process (2g) (2k) is recorded in the first recording device 40 of FIG. If it is not ″ * ″, it transmits the runaway sound in the process of (2l).

If it is determined in the digit 2u 'process transmitted to the first recording device 40 or the second recording device 50, and is ″ 1 ″, the call restriction function is deleted to the downtown area, and it is determined again in the process (2w'). If ″ 2 ″, the relevant data is recorded so that the lake can be forwarded to the international call by deleting the call restriction function to the suburban area. When the recording is completed, the confirmation tone (degree, US, brush sound) is sent to the subscriber ST1 through the subscriber network 0 to indicate that the call restriction function deletion is completed.

Referring to FIG. 2, the process (2a) is described in detail with reference to FIG. 3. When the subscriber state change is received from the subscriber network to the first central processing apparatus in the process (3a), the first process is performed in the process (3b). 2 Check how the central processing unit has changed from the previous state. When the change is made in the previous state in step (3b), it checks whether the subscriber (ST1) is hooked off in step (3c) and performs hook-on processing when the hook is on, and goes to step (2b) of FIG. 2 when the hook is off. If it does not change in the previous state in step (3b), the information of the next subscriber network is repeatedly processed.

Referring to FIG. 2, the process (2b) is described in detail with reference to FIG. 4. In step 4a, the signal processing unit 60 reads the push button signal reception state through the signal matching device 70 (4b). In step (4c), check whether there is a signal reception or valid signal application, and when the received signal is valid, perform the process (2c) and process all push button reception data when the signal is not received or is not valid data. When the checker processing device 70 checks and fails to process all of the processes (4d), the process repeats the process by taking the number of the next pushbutton receiving data (4e).

As described above, the subscriber dials directly, without going through the telephone domestic exchange maintainer, and checks the digits of the call restriction function subscriber in the exchange to automatically change and cancel the call restricted area. The time according to the change and cancellation is shortened and there is an advantage of reducing the work of the exchanger maintenance.
