Abstract

PURPOSE: A number processing method for a caller information display prohibition in a full electronic exchanger is provided to prevent personal information from unintentionally leaking by making a digit of '1585' code without an additional operator instruction word and not displaying the caller information to a callee by call units. CONSTITUTION: When a caller makes a phone call to a callee, a subscriber control block request a number translation of '1585' plus a real destination number(PfxTranSubsRQ). The number translation block translation the '1585' code, informs the subscriber control block that it is a code for a call unit prevention(CallBLKSvcRP) and transmits the digit of the code. The subscriber control block of the caller transmits the real destination number except as many as the number of the digits of the received code to the number translation block and requests again a number translation(PfxTranSubsRQ). The number translation block requests a routing for an outgoing from a route control block(RoutingRQ), requests an outgoing occupancy from a caller party ISDN user control block(IsupOgtSzRQ), and transmits an initial address message(IAM) carrying a caller information display prevention(CID blocking) information to the exchanger of the callee. Then, the ISDN user control block of the callee party exchanger requests translation for the received number from the number translation block(PfxTranTrkRQ). The number translation block translates the received number and requests a destination occupancy from the subscriber control block(CdSubsSzRQ). Then, frequency shift keying data are constructed with a display unavailable code 'P' instead of an origination number and the caller name.

전전자교환기에서 발신자정보표시금지를 위한 번호처리 방법{Delivery number handling method for calling identity delivery blocking in electronic switching system}Delivery number handling method for calling identity delivery blocking in electronic switching system

본 발명은 전전자교환기에서 발신자정보표시금지를 위한 번호처리 방법에 관한 것으로, 보다 상세하게는 발신자 정보를 착신 가입자에게 표시하지 않도록 한 방법에 관한 것이다.The present invention relates to a number processing method for prohibiting caller information display in an electronic switchboard, and more particularly, to a method of not displaying caller information to a called subscriber.

현재, 발신자가 전화를 걸게 되면 착신측의 단말기에 발신자의 정보(예컨대, 전화번호 또는 이름)가 디스플레이되도록 하여 착신자가 이를 확인한 후 전화를 받을 수 있도록 하는 기술이 연구되고 있는 상황이다.Currently, when a caller makes a call, a technology is being studied in which a caller's information (eg, a phone number or a name) is displayed on a terminal of a called party so that the called party can receive a call after confirming it.

그러나, 아직까지 발신자의 정보가 착신측에서 확인할 수 없도록 하는 기술은 연구되지 않고 있다.However, a technique for preventing the caller's information from being confirmed by the called party has not been studied.

따라서, 본 발명은 상술한 종래의 사정을 감안하여 이루어진 것으로, 착신 가입자측에서 발신자의 정보를 임의대로 확인해 볼 수 없도록 한 전전자교환기에서 발신자정보표시금지를 위한 번호처리 방법을 제공함에 그 목적이 있다.Accordingly, the present invention has been made in view of the above-described conventional situation, and an object thereof is to provide a number processing method for prohibiting caller information display in an electronic switchgear in which a called party's information cannot be arbitrarily checked. have.

상기한 목적을 달성하기 위해 본 발명의 바람직한 실시예에 따른 전전자교환기에서 발신자정보표시금지를 위한 번호처리 방법은, 발신가입자가 호 단위 방지 코드와 함께 착신 번호를 눌러 호 단위 발신자 정보 표시 방지 호를 시도하는 과정;In order to achieve the above object, a number processing method for prohibiting caller information display in an electronic switch according to a preferred embodiment of the present invention, the caller by pressing the called number together with the call-by-call prevention code, call-by-caller information display prevention call The process of trying;

상기 시도된 호가 호 단위 발신자 정보 표시 방지 호로 판명되면 상기 호 단위 방지 코드를 제외한 실제 착신 번호에 대한 번호번역을 행하는 과정;If the attempted call is found to be a call-by-call information display prevention call, performing a number translation on the actual called number except for the call-by-call prevention code;

상기 실제 착신 번호로 라우팅 정보를 구하여 해당하는 착신 교환기로 발신자 정보 표시 방지 정보를 포함하여 초기 어드레스 메시지를 착신측으로 보내는 과정; 및Obtaining routing information from the actual called number and sending an initial address message to the called party including information indicating prevention of calling party information to a corresponding called exchange; And

상기 착신측에서 번호번역을 행하여 해당 착신 가입자에게 착신점유를 요구하고, 발신자 정보를 표시하지 않는 과정을 구비한다.Performing a number translation on the called party, requesting the called party to occupy the called party, and not displaying the calling party information.

도 1은 본 발명의 실시예에 따른 발신자 정보표시금지를 위한 번호처리 방법을 설명하는 흐름도이다.1 is a flowchart illustrating a number processing method for prohibiting caller information display according to an embodiment of the present invention.

이하, 첨부된 도면을 참조하여 본 발명의 실시예를 보다 상세히 설명한다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명의 실시예에 따른 발신자정보표시금지를 위한 번호처리 방법을 설명하는 흐름도이다.1 is a flowchart illustrating a number processing method for prohibiting caller information display according to an embodiment of the present invention.

본 발명의 실시예는 호 단위 방지 코드를 먼저 번역한 후 실제 착신번의 번역이 이루어진다.In an embodiment of the present invention, the call unit prevention code is first translated and then the actual called number is translated.

상기 호 단위 방지 코드 "1585"는 운용자 명령어에 의해 생성된다. 발신자가 통화 개시전에 상기 호 단위 방지 코드 "1585"를 입력함으로써 활성화된다.The call protection code "1585" is generated by an operator command. A caller is activated by entering the call protection code " 1585 " before initiation of a call.

발신자(a)가 착신자(b)에게 전화를 걸게 되면 가입자 제어 블럭(ASCa; Analog Subscriber Control Block)에서 "1585 + 실제 착신번" 의 번호번역을 요구(PfxTranSubsRQ)한다.When the caller (a) calls the called party (b), the subscriber control block (ASCa) requests a number translation ("PfxTranSubsRQ") of "1585 + actual called party number."

그에 따라, 번호 번역 블록(NTR; Number Translation Block) 에서 "1585" 코드를 번역한다. 그 결과, 호단위 방지를 위한 코드임을 상기 가입자 제어 블럭(ASCa)에게 통보(CallBLKSvcRP)하고, 코드의 자리수를 전송한다.Accordingly, the code " 1585 " is translated in the Number Translation Block (NTR). As a result, the subscriber control block (ASCa) is notified (CallBLKSvcRP) of the code for call-by-call prevention, and the number of digits of the code is transmitted.

상기 발신자(a)의 가입자 제어 블럭(ASCa)은 결과로 받은 코드의 자리수 만큼을 제외한 실제 착신번을 번호 번역 블럭(NTR)으로 보내 다시 번호번역을 요구(PfxTranSubsRQ)한다. 이 때 방지호임을 알리는 정보가 전송된다.The subscriber control block (ASCa) of the sender (a) sends the actual called number except the number of digits of the result code to the number translation block (NTR) and requests number translation again (PfxTranSubsRQ). At this time, information indicating that the protection code is transmitted.

상기 번호 번역 블럭(NTR)에서는 실제착신 번호로 라우팅 정보를 구하여 루트 제어 블럭(RCO; Route Control Block)으로 보내고, 그 루트 제어 블럭(RCO)에서는 ISDN사용자부 제어 블럭(UPCa; ISDN User Part Control Block)을 통해 해당 교환기(즉, 착신자(b)가 가입된 착신 교환기)로 발신자 정보표시 방지(CID blocking) 정보를 포함하여 초기 어드레스 메시지(IAM; Initial Address Message)를 전송한다. 즉, 상기 번호 번역 블럭(NTR)에서 루트 제어 블럭(RCO)으로 출중계에 대한 루팅요구(RoutingRQ)를 하고, 다시 발신자(a)측의 ISDN사용자부 제어 블럭(UPCa; ISDN User Part Control Block)으로 출중계 점유요구(IsupOgtSzRQ)를 하게 된다. 그리고, 발신자 정보표시 방지(CID blocking) 정보를 싣고 초기 어드레스메시지(IAM; Initial Address Message)를 착신자측의 교환기로 전송한다.The number translation block (NTR) obtains routing information based on the actual called number and sends the route information to a route control block (RCO). The route control block (RCO) provides an ISDN user part control block (UPCa). Transmits an initial address message (IAM) including CID blocking information to a corresponding exchange (that is, a destination exchange to which the called party b is subscribed). That is, a routing request (RoutingRQ) for the outgoing call from the number translation block (NTR) to the root control block (RCO), and again the ISDN user part control block (UPCa) on the calling party (a) side. In this case, the outgoing occupancy request (IsupOgtSzRQ) is made. Then, the CID is loaded with CID blocking information and an Initial Address Message (IAM) is transmitted to the exchange at the called party.

그에 따라, 착신 교환기내의 ISDN사용자부 제어 블럭(UPCb; ISDN User Part Control Block)은 번호 번역 블럭(NTR)에게 수신된 번호(즉, 발신정보방지 기능이 부여된 번호임)에 대한 번역을 요구(PfxTranTrkRQ)하며, 그 번호 번역 블록(NTR)은 수신된 번호를 번역하여 가입자 제어 블럭(ASCb; Analog Subscriber Control Block)에게 착신점유를 요구(CdSubsSzRQ)하면 발신번호와 발신자 이름 정보 대신 표시불가 코드 "P"로 FSK(Frequency Shift Keying)데이터를 구성한다.Accordingly, the ISDN User Part Control Block (UPCb) in the destination exchange requests translation from the number translation block (NTR) to the received number (i.e., the number to which the calling information prevention function is given). (PfxTranTrkRQ), and the Number Translation Block (NTR) translates the received number and requests an incoming call from the Analog Subscriber Control Block (ASCb) (CdSubsSzRQ). P "to configure the frequency shift keying (FSK) data.

한편, 본 발명에서의 부가서비스 수행시 "1585" 처리는 다음과 같다.On the other hand, when performing the additional service in the present invention "1585" processing is as follows.

발신 부가서비스도 일반 호와 동일하게 발신자가 통화 개시전 호 단위 방지 코드 "1585"를 입력하므로써 활성화된다. 부가 서비스 등록/확인/삭제 등의 가입자 활성화시 착신번에 1585 코드를 포함하면 번호번역부(NTR)에서 이를 인지하고 1585를 제외한 실제 착신번의 번호번역을 수행하게 한다. 착신 호 전환 서비스를 가입자가 활성화할 때 * 88 + 1585 + 최종착신번 * 은 허용되지 않는다.The calling supplementary service is activated like the general call by the caller entering the call prevention code "1585" before the call. When the subscriber activates additional services such as registration / confirmation / deletion, including the 1585 code in the called party, the number translation unit (NTR) recognizes this and performs the translation of the actual called party except 1585. When the subscriber activates the forwarding service, * 88 + 1585 + called party number * is not allowed.

그리고, 상기 "1585" 코드의 생성시 정보는 공중전화에서는 사용할수 없는 코드 즉, CBX_RETRICTION으로 된다. 비과금 처리되도록 하며, 이 정보는 수정할 수 없다.When generating the "1585" code, the information becomes a code that cannot be used in a public telephone, that is, CBX_RETRICTION. Non-billable, this information cannot be modified.

이상 설명한 바와 같은 본 발명에 의하면, 별도의 운용자 명령어없이 "1585"코드를 디지트함으로써 호단위로 발신자의 정보를 착신가입자에게 표시하지 않게 하므로 원하지 않는 개인의 정보유출을 막을 수 있다.According to the present invention as described above, by digitizing the "1585" code without a separate operator command so that the caller's information is not displayed to the called party on a call-by-call basis, unwanted information leakage can be prevented.

한편, 본 발명은 상술한 실시예로만 한정되는 것이 아니라 본 발명의 요지를 벗어나지 않는 범위내에서 수정 및 변형하여 실시할 수 있고, 이러한 수정 및 변경 등은 이하의 특허 청구의 범위에 속하는 것으로 보아야 할 것이다.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.
