Outgoing call restriction service method by subscriber in electronic switching center

The present invention relates to a calling party restriction service method by a subscriber in an electronic switchgear, and more specifically, to a subscriber registered in a calling party restriction service for an international call or a long distance call to a international call or a long distance call. The present invention relates to a method of limiting calling number by a subscriber in an electronic switching system that is capable of performing international call or long distance call when a password identical to a password given at a call attempt is input.

In general, an office that does not have a public telephone facility has a high-cost long-distance call, allowing local subscribers to use the subscriber's phone only at the request of the customer or at the office to provide convenience to the customer. (B) It is common to register for calling limit services provided by telephone exchanges to limit international calls.

This calling party restriction service may cause the subscriber to register the long distance or international call restriction service with the telephone company, and the telephone company will keep the information about the subscriber. In addition, the service is provided to restrict intercity or international calls by outputting recorded announcements.

According to the conventional calling party restriction service method, since long distance or international calls cannot be made through a telephone to which a subscriber number registered in the service is assigned, a long distance call or international call should be attempted. Inevitably, it was inconvenient to install a new phone which is not registered in the call limit service or use another phone such as a public phone.

The present invention has been made in view of the above-described circumstances, and it is possible to provide a subscriber in an all-electronic exchange that enables call processing services for long distance or international calls only for subscribers who know the password by registering the password together when joining outgoing call restriction service. Its purpose is to provide a service method for limiting the calling number.

According to an embodiment of the present invention for achieving the above object, if the subscriber who wants to limit the calling party presents the desired password when registering the calling party restriction service on the exchange, the operator of the exchange using the PC uses the calling party's calling party number. Registering a restricted service and the password; A second step in which the calling party restriction service registration data and the password data registered by the exchange operator are authorized by the MMP to the NTP in the INS and stored in the number-related database in the NTP; A third step of determining whether the call is a local call by translating the called party's called number by the NTP based on the calling party's calling number when the subscriber registered to the calling party restriction service attempts to call the call; A fourth step of transmitting the announcement broadcast according to the password to the calling subscriber by requesting the announcement broadcast for inputting a password to the GSP, if it is determined that the called number is not a local call; A fifth step of determining whether the NTP matches the password registered in the database with the input number when the calling subscriber inputs the password in response to the voice message requesting the password input; If it is determined that the numbers in the above step is the same, the NTP requests the incoming ASP to receive the call, the sixth step of performing a call processing according to the normal long distance or international calls, characterized in that Calling restriction service method by subscriber in is provided.

Preferably, if it is determined in the fifth step that the password registered in the database of the NTP 18 and the password inputted by the calling party do not match, the NTP 18 sends a password to the GSP 37. Receiving the announcement broadcast according to the discrepancy, transmitting the announcement broadcast according to the password mismatch to the calling subscriber and in the step, the NTP 18 counts the number of discrepancies between the registration number and the input number registered in the database as a counter. If the number exceeds the predetermined number of times, requesting the call to the LSP (7) characterized in that it further comprises the step of sending a call tone to the calling subscriber.

According to the present invention composed of the above steps, when the subscriber attempts to intercity code or international call by registering the password together when registering the calling number restriction service, if the password is input according to the announcement, normal call processing for the intercity call or international call The service can be provided.

Read the specific recorded data of the recorded data and reproduce the processing to output a specific voice message.

Hereinafter, with reference to the flowchart shown in Figure 2 will be described in detail the calling party limit service method by the subscriber in the electronic switch according to an embodiment of the present invention.

First, when a subscriber presents his / her desired password at the time of registration of the call limit service to the operator of the exchange (step 50), the exchange operator registers the call limit service and the password of the subscriber using the PC, where the Call limit service registration data and password data registered through the PC 26 is the IPCU 23 of the CCS 300 and the HIPCU of the INS 200 by the MMP 25 performing a dialogue function between the operator and the system. It is applied to NTP 18 via 17 and stored in the numbering database in NTP 18 (step 52).

Next, if the calling party limited service subscriber detects a state in which the receiver hooks off the receiver to attempt a call by the ASIP 1 (step 54), the ASIP 1 determines the calling party and calling class for the subscriber. Data is transmitted to the ASP 11 and the ASI 3 controls the LSP 7 so that the dial tone generated in the LSI 8 is transmitted through the TSL 6 and the ASI 3 through the subscriber. To A.

Subsequently, when the calling party A dials the called party, the ASP 11 receives the digit corresponding to the called party number through the IPCU 10 and the HIPCU 17 after receiving the last digit of the called party. Request a number translation to determine if the call is a city call (step 56).

If it is determined in step 56 that the call is a local call (YES in step 56), the NTP 18 performs normal local call processing by requesting the called party's incoming call to the destination ASP. (Step 58).

If it is determined in step 56 that the call is not a local call as a result of the number translation in the NTP 18 (NO in step 56), the NTP 18 communicates with the GSP through the HIPCU 17 and the IPCU 28. The broadcast request is transmitted to the 37 to receive the password input. Accordingly, the TSL 34-CDL 21 receives the corresponding voice message generated from the GSI 38 under the control of the GSP 37. It is transmitted to the calling party ASI 3 via the SSW 15 -CDL 13-TSL 6 and forwarded to the calling party A (step 60).

Subsequently, when the subscriber A who listened to the voice guidance message inputs a password (step 62), the input password digit is transmitted by the ASP 11 through the IPCU 10 and the HIPCU 17 through the NTP 18. Where the NTP 18 determines whether the input number matches the password registered and stored in the database for the subscriber A (step 64).

As a result of the determination, if it is determined that the password registered in the database of the NTP 18 and the input number match (YES in step 64), the NTP 18 requests the incoming ASP to receive the call, thereby making a normal out-of-bound call or Ensure that call processing is performed in accordance with international calls (step 68).

On the other hand, if it is determined in step 64 that the password entered by the originating subscriber and the password registered in the database of the NTP 18 do not match (NO in step 64), the NTP 18 returns to the GSP 37. It requests the transmission of the password error announcement, and under the control of the GSP 37, the voice message generated from the GSI 38 is read and the TSL 34-CDL 21-SSW 15 is read. -Transmitted to the calling party ASI 3 via the CDL 13 -TSL 6 and forwarded to the calling party A (step 70).

Subsequently, the NTP 18 counts the number of inconsistencies between the registration number data and the input number data registered in the database of the NTP 18 with a counter (step 72), and if the counting count is determined to be two or less (step 72). NO at 72), the process returns to step 60 to send a voice message for receiving the password input generated by the GSI 38 to receive the password input up to two times.

If it is determined in step 72 that the number of inconsistencies between the registration number data and the input number data registered in the database of the NTP 18 has been counted two or more times (YES in step 72), the NTP 18 determines the HIPCU ( 17) and the call request to the LSP (7) through the IPCU (10), and accordingly the call sound is read from the LSI (8) to the subscriber through the TSL (6) -ASI (3) Allow the ringtone to be connected (step 74).

According to the present invention made as described above, the subscriber registered in the call limiting service does not have to use the other phone to receive long distance or international call service, and there is no additional expense of installing a new phone.
