Description
본 발명은 이동통신 지능망 서비스에서의 일반 호 전환방법에 관한 것이다. 보다 상세하게는 지능망 서비스에서의 고장 발생시 실시간 호 전환에 의해 지능망 가입자에게 일반 호를 제공토록 하는 기술에 관한 것이다.The present invention relates to a general call transfer method in a mobile communication intelligent network service. More specifically, the present invention relates to a technology for providing a general call to an intelligent subscriber by real-time call switching when a failure occurs in the intelligent network service.
일반적으로 이동통신망에서는 여가가지 부가서비스를 제공하고 있으며, 그 중 하나의 서비스가 호전환 서비스이다. 호전환 서비스란 가입자가 전화 받기를 원하지 않거나 연결이 되지 않을 때, 다른 번호로 호를 연결해 주는 서비스이다. 호전환 서비스는 호전환 방법에 따라 몇 가지 부류로 나눌 수 있다. In general, a mobile communication network provides a variety of additional services, one of which is a call transfer service. Transfer service is a service that connects a call to another number when the subscriber does not want to answer or cannot be connected. Call transfer services can be divided into several categories depending on the call transfer method.
우선, 조건부 호전환과 무조건 호전환이 있다. 조건부 호전환은 가입자의 위치를 알 수 없거나, 가입자가 전화를 받지 않거나, 통화 중일 때 다른 번호로 연결해 주는 서비스를 말하고, 무조건 호전환이란 가입자를 호출하지 않고 다른 번호로 연결해 주는 서비스이다. 전자를 " 자동연결서비스 " 라고 하고, 후자를 " 착신전환서비스 " 라고 한다.First, there are conditional and unconditional call transfers. Conditional transfer refers to a service that connects to another number when the subscriber's location is not known, the subscriber does not answer a call, or is busy. Unconditional transfer is a service that connects to another number without calling the subscriber. The former is called "automatic linkage service" and the latter is called "call forwarding service".
호전환이 어디로 연결되는냐에 따라서도 구분되는데, 자동연결서비스나 착신전환서비스는 어떤 번호로도 연결되는 반면에, 음성사서함(VMS) 서비스를 이용하는 이동가입자는 음성사서함(VMS)으로 착신전환이나 자동연결을 설정할 수 있다. 호재설정 요구(Redirection Request) 메시지는 조건부 호전환에 사용된다.It is also classified according to where the call transfer is connected. The automatic connection service or the call forwarding service is connected to any number, while the mobile subscriber who uses the voice mail service (VMS) is transferred to the voice mailbox (VMS). You can establish a connection. Redirection Request messages are used for conditional call forwarding.
도 1은 종래 기술에 따른 이동통신 지능망 서비스에서의 호처리 과정을 나타낸 흐름도이다.1 is a flowchart illustrating a call processing process in a mobile communication intelligent network service according to the prior art.
먼저, 발신 가입자가 호를 시도하면, 발신 교환국(10)이 착신가입자의 위치정보를 얻기 위해 홈위치등록기(HLR)(20)로 위치등록 요구신호를 전송한다(S10). 위치등록 요구신호를 수신한 HLR(20)에서는 착신교환국(30)으로 착신가입자의 루팅 정보를 요구한다(S20).First, when the calling subscriber attempts to make a call, the calling switching center 10 transmits a location registration request signal to the home location register (HLR) 20 to obtain the location information of the called subscriber (S10). Upon receiving the location registration request signal, the HLR 20 requests routing information of the called party to the destination switching center 30 (S20).
그러면, 홈위치등록기(HLR)가 착신가입자가 로밍해 있는 착신 교환국(30)으로부터 착신가입자의 루팅 정보를 전달 받는다(S30).Then, the home location register (HLR) receives the routing information of the called subscriber from the destination switching center 30 where the called subscriber roams (S30).
이후, 착신 교환국(30)으로부터 전달 받은 루팅 정보를 발신 교환국(10)에 반송해준다(S30). 그러면, 발신 교환국(10)은 이 루팅 정보를 이용해 착신 교환국(30)과 음성 통화로를 할당하게 된다(S40).Thereafter, the routing information received from the destination switching center 30 is returned to the calling switching center 10 (S30). Then, the source switching center 10 allocates a voice call path with the destination switching center 30 using this routing information (S40).
이러한 종래의 호처리 과정에 있어서 지능망 서비스에 고장이 발생할 경우에는 HLR에서 지능망의 서비스 식별번호(Service Access Code; SAC) 제한을 통해 착신교환국에서 HLR로 SAC과 착신(Destnation) 이동식별번호(Mobile Identification Number; MIN)를 함께 실어 보내게 된다.In case of failure of the intelligent network service in the conventional call processing, the SAC and the destination mobile identification number from the destination exchange station to the HLR through the restriction of the service access code (SAC) of the intelligent network in the HLR. Number (MIN) will be sent together.
이는 HLR에서 지능망 호를 처리시 이동통신지능망(Wireless Intelligent Network; WIN) 접두 디지트(Prefix Digit)의 어드레스 자릿수가 4자리에서 10자리로 기 설정되어 접두 디지트의 값은 확정된 자릿수 안에서 변경이 가능하나, 일반 호를 처리하기 위한 디지트를 " 0자리 "로 변경할 수 있는 WIN 트리거 디지트(Trigger Digit)의 삭제 기능이 없었다. 따라서, 지능망 서비스 고장 시 일반 호의 전환 시간이 장시간 소요됨으로써 다음과 같은 문제점을 초래한다.This is because the address digits of the Wireless Intelligent Network (WIN) prefix digit are set to 4 to 10 digits when the HLR processes an intelligent network call, so the value of the prefix digit can be changed within the defined number of digits. There was no clearing of the WIN Trigger Digit, which could change the digits for normal calls to "zero digits." Therefore, when the intelligent network service breaks down, it takes a long time to switch a general call, which causes the following problems.
첫째, 지능망 가입자의 이동전화 사용이 중단되며; 둘째, 백업시스템이 구축되어 있으나 수용서비스가 다양하여 잦은 S/W 변경으로 원할한 백업 절체가 이루어지지 않게 된다. 특히, 백업 절체가 성공적으로 이루어지더라도 약 10분이 소요된다.First, the use of the mobile phone of the intelligent network subscriber is stopped; Second, although the backup system is established, the service is diversified, so frequent backup changes are not made due to frequent S / W changes. In particular, it takes about 10 minutes even if the backup transfer is successful.
셋째, 지능망 서비스 고장시 전국 이동통신교환국(MSC)에서 지능망 가입자의 발신 Trigger(SAC Code)에 대하여 4-Digit 삭제를 수행하여 일반 호처리하므로써 약 15분간 소요된다.Third, in case of an intelligent network service failure, it takes about 15 minutes by performing 4-Digit deletion on the originating trigger (SAC Code) of the intelligent network subscriber in the MSC.
넷째, 이동통신교환국(MSC)가 전국적으로 분포되어 통제 및 관리에 어려움이 많아 실질적으로 지능망 호의 일반 호 전환 작업이 이루어지지 않는 지역도 발생하는 문제점이 초래된다.Fourth, since MSCs are distributed nationwide, they are difficult to control and manage, resulting in areas where virtual network calls are not generally made.
본 발명은 상기한 문제점을 해결하기 위한 것으로서 본 발명은 지능망 서비스의 고장 발생시 실시간 호 전환에 의해 지능망 가입자에게 일반 호를 제공함으로써 지속적인 통화가 가능토록 하는데 그 목적이 있다.The present invention is to solve the above problems, the present invention is to provide a continuous call to the intelligent network subscribers by the real-time call switching when the failure of the intelligent network service is to enable a continuous call.
상기한 본 발명의 목적을 달성하기 위한 기술적 사상으로서 본 발명은As the technical idea for achieving the above object of the present invention

이하, 본 발명의 실시예에 대한 구성 및 그 작용을 첨부한 도면을 참조하면서 상세히 설명하기로 한다.Hereinafter, with reference to the accompanying drawings, the configuration and operation of the embodiment of the present invention will be described in detail.
본 발명에 의한 이동통신 지능망 서비스에서의 일반 호 전환 방법을 설명하기에 앞서 일반적인 이동 통신망의 시스템을 살펴보기로 한다.Before describing a general call transfer method in a mobile communication intelligent network service according to the present invention, a system of a general mobile communication network will be described.
이동 통신망은 홈위치등록기(HLR), 이동통신교환기(MSC), 방문자위치등록기(VLR), 기지국(BS) 및 이동국(MS) 등과 그 외의 여러 부가장비로 이루어져 있다. The mobile communication network consists of a home location register (HLR), a mobile communication exchange (MSC), a visitor location register (VLR), a base station (BS), a mobile station (MS), and many other additional equipment.
상기 홈위치등록기(HLR : Home Location Register)는 가입자의 위치정보 및 부가서비스 정보 등을 가지고 있는 데이터베이스로서, 서비스를 통제하는 역할도 하고 있다. 이동통신교환기(MSC : Mobile Switching Center)는 이동전화가입자가 전화를 걸거나 받을 때 호를 연결하고, 방문자위치등록기(VLR : Visitor Location Register)는 이동통신교환기가 서비스하는 지역의 방문가입자의 정보를 저장하고 있다.The home location register (HLR) is a database having subscriber location information and additional service information, and also serves to control services. Mobile Switching Center (MSC) connects calls when mobile subscribers make or receive calls, and Visitor Location Register (VLR) displays visitor information in the area serviced by mobile switch. Saving.
기지국(BS : Base Station)은 기지국 제어기(BSC)와 기지국 송수신 서브시스템(BTS)으로 구성되어 있으며, 기지국 제어기(BSC : Base Station Controller)와 기지국 송수신 서브시스템(BTS : Base station Tranceiver Subsystem)은 이동통신 교환기와 가입자 사이에서 유/무선간의 인터페이스 기능을 담당한다. 이동국(MS : MobileStation)은 단말기를 소지한 이동가입자를 지칭한다. A base station (BS) is composed of a base station controller (BSC) and a base station transmit / receive subsystem (BTS), and the base station controller (BSC) and base station transmit / receive subsystem (BTS) are moved. It is in charge of the wire / wireless interface function between the communication switch and the subscriber. A mobile station (MS) refers to a mobile subscriber who has a terminal.
보통 1개의 서비스 망에는 다수의 홈위치등록기(HLR)가 존재할 수 있고, 1개의 홈위치등록기(HLR)에는 1개 또는 그 이상의 이동통신교환기/방문자위치등록기가 접속될 수 있으며, 1개의 이동통신교환기에는 여러 개의 기지국(BS)이 접속될 수 있다.Usually, there can be multiple home location registers (HLRs) in one service network, one home location register (HLR) can be connected to one or more mobile switching centers / visitor location registers, and one mobile communication. Several base stations (BS) may be connected to the exchange.
도 2는 본 발명에 따른 이동통신 지능망 서비스에서의 일반 호 전환 과정을 나타낸 흐름도이다.2 is a flowchart illustrating a general call transfer process in a mobile communication intelligent network service according to the present invention.
지능망 서비스의 고장 발생시 발신 가입자가 호를 시도하면, 발신 교환국(10)이 착신가입자의 위치정보를 얻기 위해 홈위치등록기(HLR)(20)로 위치등록 요구신호를 전송한다(S10). 위치등록 요구신호를 수신한 HLR(20)에서는 착신교환국(30)으로 착신가입자의 루팅 정보를 요구한다(S20).When the originating subscriber attempts to make a call when a failure of the intelligent network service occurs, the originating switching center 10 transmits a location registration request signal to the home location register (HLR) 20 to obtain the location information of the called party (S10). Upon receiving the location registration request signal, the HLR 20 requests routing information of the called party to the destination switching center 30 (S20).
그러면, 홈위치등록기(HLR)가 착신가입자가 로밍해 있는 착신 교환국(30)으로부터 착신가입자의 루팅 정보(착신 이동식별번호(Destnation MIN))를 전달 받는다(S30).Then, the home location register (HLR) receives the routing information (destination MIN) of the called subscriber from the destination switching center 30 where the called subscriber roams (S30).
이 때, 종래 기술에서는 HLR(20)에서 지능망의 서비스 식별번호(SAC) 사용 제한을 통해 착신교환국(30)에서 HLR(20)로 SAC과 착신 MIN를 함께 실어 보냈으나, 본 발명에서는 Destnation MIN 만을 실어보내게 된다.At this time, in the prior art, the SLR and the destination MIN are sent together from the destination switching center 30 to the HLR 20 through the restriction of the use of the service identification number (SAC) of the intelligent network in the HLR 20, but in the present invention, only the Destnation MIN is carried. Will be sent.
이는 WIN 트리거 디지트(Trigger Digit) 자릿수 관리 범위를 확장하여 WIN 접두 디지트(Prefix Digit)의 어드레스 자릿수가 " 0자리에서 10자리(종래에는 4자리에서 10자리) "로 변경됨으로써 지능망 서비스의 고장에서도 가입자에게 실시간으로 일반 호의 전환이 가능하게 된다.This extends the WIN Trigger Digit digit management range to change the address digits of the WIN Prefix Digit from "0 to 10 digits (formerly 4 to 10 digits)." This allows the general call to be transferred in real time.
즉, 발신 교환국(10)에서는 지능망 WIN 트리거가 없는 디지트를 수신하여 지능망이 아닌 일반 호로 해석하여 위치등록 요구에 응답하게 된다.That is, the originating switching center 10 receives a digit without an intelligent network WIN trigger, interprets it as a general call, not an intelligent network, and responds to a location registration request.
이후, 착신 교환국(30)으로부터 전달 받은 루팅 정보를 발신 교환국(10)에 반송해준다(S40). 그러면, 발신 교환국(10)은 이 루팅 정보를 이용해 착신 교환국(30)과 음성 통화로를 할당하게 된다(S50).Thereafter, the routing information received from the destination switching center 30 is returned to the calling switching center 10 (S40). Then, the source switching center 10 allocates a voice call path with the destination switching center 30 using this routing information (S50).
이상에서와 같이 본 발명에 의한 이동통신 지능망 서비스에서의 일반 호 전환방법에 따르면, 지능망 서비스의 고장 발생시 실시간 호 전환에 의해 지능망 가입자에게 일반 호를 제공함으로써 지속적인 통화가 가능토록 하여 지능망 서비스의 무(無) 고장 기반을 확보할 수 있으며, 지역별 이동교환기의 일반 호 전환 소요시간에 대한 편차를 제거할 수 있으며, 일반 호 처리에 대한 요금 정산시 객관화된 기준 시간의 도출이 가능하다.As described above, according to the general call switching method in the mobile communication intelligent network service according to the present invention, when a failure of the intelligent network service occurs, the general call is provided to the subscribers of the intelligent network by real-time call switching so that continuous calls can be made. Fault-free base can be secured, the deviation of the general call transfer time of the regional mobile exchange can be eliminated, and the standardized reference time can be derived when calculating the charge for general call processing.
