Abstract

PURPOSE: A method for adding and deleting a base station in a digital mobile communication system is provided to add or delete the base station without having an influence on a subscriber service provision by a system by changing PLD(Program Load Data) of a BSM(Base Station Manager), a BSC(Base Station Controller) and a base station on the basis of information of an added or deleted base station, loading a newly generated PLD to only the added base station, and operating the added base station. CONSTITUTION: A BSM receives information of an added or deleted base station from an operator(S1). The BSM transmits received information of the base station, information extracted from PLD of a BSC and a base station to a BSC and a base station which provide a service through a trunk so that the BSC and the base station change their PLD(S2). The BSM changes PLD on the basis of information of the added or deleted base station until a PLD change response is received from the BSC and the base station(S3). If the base station is added, the BSM generates PLD used in the added new base station on the basis of information of the added base station and information extracted from the PLD of the BSC and the base station which provide the service(S4). If the generation of the PLD is completed, the BSM loads the generated PLD and a software to the added new base station(S5).

디지털 이동통신 시스템에서의 기지국 추가/삭제방법How to add / remove base station in digital mobile communication system

본 발명은 디지털 이동통신 시스템에 있어서, 운영자에 의한 기지국 운영 관리기(Base Station Manager ; 이하, 'BSM'이라 칭함)의 명령에 따라 제어국과 기지국의 PLD(Processor Load Data)를 제한적으로 변경할 수 있음을 이용하여 추가 또는 삭제되는 기지국의 정보가 반영되도록 BSM, 제어국, 기지국의 PLD를 변경하고,추가되는 기지국만이 새로 생성되는 PLD를 로딩(Loading)받아 동작함으로써 시스템에 의한 가입자 서비스 제공에 전혀 영향을 주지않고 기지국을 추가 또는 삭제할수 있도록 한 디지털 이동통신 시스템에서의 기지국 추가 및 삭제방법에 관한 것이다.According to the present invention, in a digital mobile communication system, a processor load data (PLD) of a control station and a base station can be changed in a limited manner according to a command of a base station manager (hereinafter referred to as "BSM") by an operator. Change the PLD of the BSM, the control station and the base station to reflect the information of the base station to be added or deleted by using, and only the added base station is operated by receiving the newly generated PLD loading to provide subscriber service by the system. The present invention relates to a method for adding or deleting a base station in a digital mobile communication system that can add or delete a base station without affecting.

일반적으로 디지털 이동통신 시스템은 도 1에 도시된 바와 같이 이동 단말국(10)과, 기지국(20)과, 상기 기지국(20)을 제어하는 제어국(30)과, 상기 기지국(20)과 제어국(30)의 상태를 관리하는 BSM(40)과, 상기 제어국(30)을 관리하는 교환국(50)으로 구성되며, 상기 기지국(20), 제어국(30),BSM(40)은 각각 관리를 위한 운영 데이터, 즉 PLD를 가지고 있다.In general, a digital mobile communication system, as shown in FIG. 1, controls a mobile terminal station 10, a base station 20, a control station 30 that controls the base station 20, and the base station 20. The base station 20, the control station 30, and the BSM 40, respectively, are composed of a BSM 40 that manages the state of the station 30 and an exchange station 50 that manages the control station 30. It has operational data for management, or PLD.

즉, 기지국(20)은 자기 자신의 동작을 위한 PLD를, 제어국(30)은 자기 자신과 자신이 관리하는 각 기지국을 위한 PLD를, BSM(40)은 자기 자신과 자신이 관리하는 모든 제어국과 기지국의 동작을 위한 PLD를 각각 가지고 있다.That is, the base station 20 is a PLD for its own operation, the control station 30 is a PLD for itself and each base station that it manages, the BSM 40 is all control itself and its own control Each has a PLD for operation of the station and the base station.

한편, 상기와 같이 구성된 디지털 이동통신 시스템에서는 초기 전체 서비스 지역과 예상 가입자 수 등을 토대로 셀 플래닝(Cell Planning)을 수행하여 필요한 기지국 수와 각 기지국의 위치 등을 결정하고 그에 따라 기지국을 설치된다.Meanwhile, in the digital mobile communication system configured as described above, cell planning is performed based on the initial total service area and the expected number of subscribers to determine the required number of base stations, the location of each base station, and the like.

이때, 디지털 이동통신 시스템에서는 여러 가지 이유, 즉 가입자의 증가/감소, 서비스 지역의 확대/축소, 음영지역 처리등을 위해 기지국의 추가 또는 삭제가 필요하다.In this case, the digital mobile communication system needs to add or delete a base station for various reasons, namely, increase / decrease of subscribers, expansion / reduction of service area, shadow area processing, and the like.

이에 따라, 종래에는 기지국의 추가 또는 삭제가 필요할 경우 오프-라인(Off-Line) 상태에서 추가 또는 삭제되는 기지국의 정보를 포함되도록 모든 PLD를 변경한 후 BSM(40)에서부터 제어국(30), 기지국(20)으로 로딩하도록 하였다.Accordingly, in the related art, when the addition or deletion of the base station is required, all the PLDs are changed to include information of the base station to be added or deleted in the off-line state, and then the BSM 40 to the control station 30, Loading to the base station 20 is made.

그러나, 상기와 같이 오프-라인(Off-Line) 상태에서 기지국의 추가 또는 삭제에 따른 PLD 의 로딩이 이루어지게 되면 PLD를 로딩하는 동안 BSM(40), 제어국(30), 기지국(20)은 가입자에게 서비스를 제공하지 못하여 서비스가 중단되게 된다.However, when the PLD is loaded in accordance with the addition or deletion of the base station in the off-line state as described above, the BSM 40, the control station 30, and the base station 20 during the loading of the PLD Failure to provide services to the subscriber will result in service interruption.

즉, 로딩중인 제어국(30), 기지국(20)의 영역 내에 존재하는 모든 가입자가 무선 전화를 사용할 수 없게 되는 문제점이 있었다,That is, there was a problem that all the subscribers existing in the area of the control station 30 and the base station 20 being loaded cannot use the wireless telephone.

또한, 시스템 운영중 필요에 따라 PLD의 내용을 수시로 변경하는 경우 기본값을 가지고 새로 PLD를 만들어야 하므로 운영중 변경된 내용이 모두 유실되게 되는 문제점이 있었다.In addition, if the contents of the PLD are changed from time to time according to the needs of the system operation, new PLDs should be created with default values, so that all the changed contents are lost during the operation.

본 발명은 상기와 같은 문제점을 해결하기 위한 것으로서, 그 목적은 운영자에 의한 BSM의 명령에 따라 제어국과 기지국의 PLD를 제한적으로 변경할 수 있음을 이용하여 추가 또는 삭제되는 기지국의 정보가 반영되도록 BSM, 제어국, 기지국의 PLD를 변경하고, 추가되는 기지국만이 새로 생성되는 PLD를 로딩받아 동작함으로써 시스템에 의한 가입자 서비스 제공에 전혀 영향을 주지 않고 기지국을 추가 또는 삭제할 수 있도록 한 디지털 이동통신 시스템에서의 기지국 추가/삭제 방법을 제공하는데에 있다.The present invention is to solve the above problems, the object of the BSM to reflect the information of the base station that is added or deleted by using a limited change of the PLD of the control station and the base station according to the command of the BSM by the operator In a digital mobile communication system in which a base station can be added or deleted without changing the PLD of a control station and a base station, and only an additional base station is loaded and operated with a newly generated PLD. The present invention provides a method for adding / deleting a base station.

이러한 목적을 달성하기 위한 본 발명에 의한 기지국 추가/삭제 방법은, BSM에서 운영자로부터 추가 또는 삭제되는 기지국의 정보를 입력받아 서비스를 제공하고 있던 제어국과 기지국이 입력받은 정보와 기존의 PLD로부터 추출되는 정보를 토대로 제어국과 기지국의 PLD를 변경하도록 하고, 이어 BSM내의 PLD도 상기 입력받은 기지국의 정보가 반영되도록 변경하면서 기지국 추가인 경우에 상기 입력받은 기지국의 정보와 기존 제어국과 기지국의 PLD로부터 추출되는 정보를 토대로 추가되는 기지국의 PLD를 생성하며, 이후 제어국을 통해 상기 생성된 PLD와 기지국 동작을 위한 각종 소프트웨어를 추가되는 신규 기지국으로 로딩하도록 함으로써 가입자의 서비스 중단없이 기지국의 추가 또는 삭제가 이루어지도록 함을 특징으로 한다.The method for adding / deleting a base station according to the present invention for achieving the above object is to extract information from a control station and a base station, which are providing a service by receiving information of a base station added or deleted from an operator in a BSM, and information received from an existing PLD. Change the PLD of the control station and the base station based on the information, and then change the PLD in the BSM to reflect the information of the received base station, and add the base station information and the PLD of the existing control station and the base station when the base station is added.

이하, 첨부된 도 2를 참고하여 본 발명에 의한 디지털 이동통신 시스템에서의 기지국 추가/삭제방법을 상세히 설명한다.Hereinafter, a method for adding / deleting a base station in a digital mobile communication system according to the present invention will be described in detail with reference to FIG. 2.

본 발명에서는 제어국 및 기지국으로 트래픽 데이터(Traffic Data), 제어신호(Contral Signal)등을 전송하기 위해 가설된 트렁크(Trunk)를 통해 BSM에서 내린 명령이 전송되어 제어국과 기지국의 PLD를 제한적으로 변경할 수 있다고 하는 점을 이용하였다.In the present invention, a command issued by the BSM is transmitted through a hypothetical trunk to transmit traffic data, a control signal, etc. to a control station and a base station, thereby restricting the PLD of the control station and the base station. The fact that it can change was used.

도 2는 본 발명에 의한 디지털 이동통신 시스템에서의 기지국 추가 및 삭제방법을 보인 흐름도로서, 먼저 BSM에서는 운영자로부터 추가 또는 삭제되는 기지국의 정보를 입력받는다(S1).2 is a flowchart illustrating a method for adding and deleting a base station in a digital mobile communication system according to the present invention. First, the BSM receives information of a base station added or deleted from an operator (S1).

이때, 기지국의 추가 또는 삭제를 위해 반드시 입력되어야 하는 최소한의 정보는 다음과 같다.At this time, the minimum information that must be input for the addition or deletion of the base station is as follows.

기지국을 추가할 경우에는 기지국 번호, 기지국 이름, 기지국 사용섹터(Sector)수, 각 섹터의 파일롯 오프셋(Pilot Offset), 사용 채널수, 각 채널의 주파수, 각 기지국 장비의 설치/미설치 여부 정보를 입력해야 하고, 기지국을 삭제할 경우에는 기지국 번호만을 입력해야 한다.When adding a base station, input base station number, base station name, base station sectors, pilot offset of each sector, number of channels used, frequency of each channel, and whether each base station equipment is installed or not. When deleting a base station, only the base station number should be entered.

이어, BSM은 상기 단계(S1)에서 입력받은 기지국 정보와 기존 제어국과 기지국 PLD로터 추출되는 정보를 트렁크를 통해 서비스를 제공하고 있던 제어국과 기지국으로 전송하여 제어국과 기지국이 자신의 PLD를 변경하도록 한다,(S2).Subsequently, the BSM transmits the base station information received in the step S1 and the information extracted from the existing control station and the base station PLD to the control station and the base station providing the service through the trunk, so that the control station and the base station transmit their own PLD. To change, (S2).

즉, 상기 제어국과 기지국의 PLD를 상기 추가 또는 삭제되는 기지국의 정보가 반영되도록 변경한다.That is, the PLD of the control station and the base station is changed to reflect the information of the base station to be added or deleted.

그리고 나서, 상기 제어국과 기지국으로부터 PLD 변경 응답을 받는 대로 BSM 자신도 상기 단계(S1)에서 입력받은 기지국 정보, 즉 추가 또는 삭제되는 기지국의 정보가 반영되도록 PLD를 변경한다.(S3).Then, upon receiving the PLD change response from the control station and the base station, the BSM itself also changes the PLD to reflect the base station information input in step S1, that is, the base station information to be added or deleted (S3).

이후, BSM은 기지국 추가인 경우에 상기 단계(S1)에서 입력받은 기지국 정보와 기존에 서비스를 제공하고 있던 제어국과 기지국의 PLD로부터 추출되는 정보를 토대로 추가되는 신규 기지국이 가지고 동작할 PLD를 생성한다.(S4).Subsequently, in the case of adding a base station, the BSM generates a PLD to be operated by a new base station added based on the base station information received in the step S1 and information extracted from the PLD of the control station and the base station previously providing the service. (S4).

상기 단계(S4)에서 신규 기지국을 위한 PLD 생성이 완료되면, BSM은 제어국을 통해 상기 생성된 PLD와 기지국 동작을 위한 소프트웨어를 추가되는 신규 기지국으로 로딩하도록 한다(S5).When generation of the PLD for the new base station is completed in step S4, the BSM causes the control station to load the generated PLD and software for base station operation to the new base station to be added (S5).

이상, 상기 설명에서와 같이 본 발명은 가입자에게 서비스를 제공중인 제어국과 기지국들의 동작에 아무런 영향없이 PLD 변경, 생성 및 로딩을 통해 기지국을추가 또는 삭제할 수 있으며, 이에 따라 가입자들의 통신 서비스가 중단되지 않을뿐만 아니라 기지국이 추가 또는 삭제될 때마다 전체 PLD를 새로 만들어야 하는 번거로움을 제거함은 물론 제작된 PLD의 안정성 검증, 운영중 수정된 부분을 재수정하는데 드는 노력을 감소시킬 수 있게 되는 효과가 있다.As described above, the present invention can add or delete base stations through PLD change, generation, and loading without affecting the operation of the control station and the base stations providing the service to the subscriber, and thus the communication service of the subscribers is interrupted. Not only does this eliminate the hassle of creating a whole PLD every time a base station is added or removed, but it also reduces the effort required to verify the stability of the fabricated PLD and to revise the modifications in operation. .
