Abstract

본 발명은 전전자 교환기에 있어서 RASP(Remote Access Switching Processor)가 시작할 경우 그 RASP가 동작에 필요한 데이터를 신속하게 로딩하도록하는 전전자 교환기의 데이터 로딩 시간 단축 방법에 관한 것으로, 종래의 기술에 있어서는 RASP가 CCP(Central Control Processor)로부터 해당 데이터를 로딩받는 시간이 상당히 많이(12분 내지 13분 정도) 걸리기 때문에 RASP의 시작이 늦어지는 결점이 있었으나, 본 발명에서는 전전자 교환기에 있어서 RASP(12)가 시작할 경우 그 RASP(12)가 동작에 필요한 데이터를 기설정된 자신의 제1 저장부로(22)부터 신속하게 로딩하도록함으로써 상술한 결점을 개선시킬 수 있는 것이다.The present invention relates to a method for shortening the data loading time of an electronic switchboard so that when the RASP (Remote Access Switching Processor) starts in the electronic switchboard, the RASP loads data necessary for operation. The start of RASP is delayed because the time required to load the corresponding data from the central control processor (CCP) is about 12 to 13 minutes. However, in the present invention, the RASP 12 is used in the electronic switchboard. In the beginning, the above-described drawbacks can be ameliorated by having the RASP 12 quickly load data required for operation from its first storage 22, which is preset.

Description

전전자 교환기의 데이터 로딩 시간 단축 방법How to shorten data loading time of electronic exchange

본 발명은 전전자 교환기의 데이터 로딩(data loading) 시간 단축 방법에 관한 것으로서, 특히 전전자 교환기에 있어서 RASP(Remote Access Switching Processor)가 시작할 경우 그 RASP가 동작에 필요한 데이터를 신속하게 로딩하도록하는 전전자 교환기의 데이터 로딩 시간 단축 방법에 관한 것이다.The present invention relates to a method for shortening the data loading time of an electronic switchgear, and more particularly, to enable the RASP to quickly load data required for operation when a RASP (Remote Access Switching Processor) starts in an electronic switchgear. The present invention relates to a method for shortening the data loading time of an electronic exchange.

이와 관련하여, 종래의 기술에 있어서 RASP(도면 중에 도시하지 않음)가 시작할 경우 그 RASP는 CCP(Central Control Processor)(도면 중에 도시하지 않음)로부터 IPC(Inter Processor Communication) 망(도면 중에 도시하지 않음) 및 1Mbps PCM 링크(Pulse Code Modulation link)(도면 중에 도시하지 않음) 전송로를 통해 해당 데이터를 로딩한다.In this regard, in the prior art, when a RASP (not shown in the figure) starts, the RASP is from an Central Control Processor (CCP) (not shown) and an IPC (Inter Processor Communication) network (not shown). And the corresponding data are loaded through a 1 Mbps PCM link (Pulse Code Modulation link) (not shown).

이때 상술한 CCP는 IPC 망과 8Mbps의 전송로를 통해 접속된다.At this time, the above-mentioned CCP is connected to the IPC network through a transmission path of 8Mbps.

그러나, 이와 같은 종래의 기술에 있어서는 RASP가 CCP로부터 해당 데이터를 로딩받는 시간이 상당히 많이(12분 내지 13분 정도) 걸리기 때문에 RASP의 시작이 늦어지는 결점이 있었다.However, this conventional technique has a disadvantage in that the start of RASP is delayed because the RASP takes a considerable time (about 12 to 13 minutes) to load the corresponding data from the CCP.

본 발명은 상술한 결점을 개선하기 위하여 안출한 것으로서, 전전자 교환기에 있어서 RASP가 시작할 경우 그 RASP가 동작에 필요한 데이터를 기설정된 자신의 저장부로부터 신속하게 로딩하도록하는 전전자 교환기의 데이터 로딩 시간 단축 방법을 제공하는 데 그 목적이 있다.SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned shortcomings. When the RASP starts in the electronic switchboard, the data loading time of the electronic switchboard allows the RASP to quickly load data necessary for operation from its own storage. The purpose is to provide a shortening method.

본 발명의 상술한 목적 및 기타 목적과 여러 가지 장점은 이 기술 분야에 숙련된 사람들에 의해 첨부된 도면을 참조하여 하기에 기술되는 발명의 바람직한 실시 예로부터 더욱 명확하게 될 것이다.The above and other objects and various advantages of the present invention will become more apparent from the preferred embodiments of the invention described below with reference to the accompanying drawings by those skilled in the art.

이하, 상술한 목적을 달성하기 위한 본 발명의 실시 예를 상세히 설명하면 다음과 같다.Hereinafter, an embodiment of the present invention for achieving the above object in detail.

도 1은 본 발명에 따른 전전자 교환기의 데이터 로딩 시간 단축 방법을 실시하기 위한 전전자 교환기의 일 실시 예를 나타낸 블록도로, RASP(12), CCP(14), INP(Interconnection Network Processor)(16), TP(Telephony Processor)(18) 및 ASP(Access Switching Processor)(20)는 IPC 망(10)을 통하여 통신한다.1 is a block diagram showing an embodiment of an all-electronic exchange for implementing a method for shortening the data loading time of the all-electronic exchange according to the present invention. The RASP 12, the CCP 14, and the INP (Interconnection Network Processor) 16 ), The Telephony Processor (TP) 18 and the Access Switching Processor (ASP) 20 communicate through the IPC network 10.

또한, 제1 저장부(22)는 HDD(Hard Disk Drive)로 이루어져 RASP(12)의 동작에 관련된 데이터를 저장하며, 제2 저장부(24)는 HDD로 이루어져 CCP(14)의 동작에 관련된 데이터를 저장한다.In addition, the first storage unit 22 is configured as a hard disk drive (HDD) to store data related to the operation of the RASP 12, and the second storage unit 24 is configured as an HDD related to the operation of the CCP 14 Save the data.

도 2는 도 1에 따른 전전자 교환기의 데이터 로딩 시간 단축 방법의 일 실시 예를 단계별로 나타낸 순서도로, RASP(12)가 시작할 경우 제1,제2 저장부(22,24)의 각 파일을 서로 비교한다(30,32).FIG. 2 is a flowchart illustrating a step-by-step embodiment of a method of reducing data loading time of an electronic switch according to FIG. 1. When the RASP 12 starts, each file of the first and second storage units 22 and 24 is displayed. Compare with each other (30, 32).

이때 상술한 비교의 실시 예를 보면, 각 파일의 크기, 체크섬(checksum)(가장 우선적으로 비교되어야 할 항목), 버전(version), 만들어진 날짜 및 업데이트(update)한 날짜 등을 비교한다.In this case, the size of each file, a checksum (an item to be compared first), a version, a created date, and an updated date are compared.

다음, 상술한 단계(30,32)에서 제1,제2 저장부(22,24)의 각 파일이 서로 같을 경우 RASP(12)는 자신의 저장 장치인 제1 저장부(22)로부터 각 파일을 로딩한다(34).Next, when the files of the first and second storage units 22 and 24 are the same in the above-described steps 30 and 32, the RASP 12 stores each file from the first storage unit 22 which is its storage device. Load (34).

또한, 상술한 단계(30,32)에서 제1,제2 저장부(22,24)의 각 파일이 서로 같지 않을 경우 RASP(12)는 CCP(14)를 통해 CCP(14)의 저장 장치인 제2 저장부(24)로부터 각 파일을 로딩한다(36).In addition, when the files of the first and second storage units 22 and 24 are not identical to each other in the above-described steps 30 and 32, the RASP 12 is a storage device of the CCP 14 through the CCP 14. Each file is loaded 36 from the second storage unit 24.

즉, 시스템 운용중에 변경되는 파일이 있을 경우 그 파일을 제1 저장부(22)에 즉시 갱신시켜 저장해 놓아야 할 것이다.That is, if there is a file that is changed during system operation, the file should be immediately updated and stored in the first storage unit 22.

이상에서 설명한 바와 같이 본 발명은 전전자 교환기에 있어서 RASP(12)가 시작할 경우 그 RASP(12)가 동작에 필요한 데이터를 기설정된 자신의 제1 저장부로(22)부터 신속하게 로딩하도록함으로써 RASP(12)의 정상적인 시작 동작이 빨라지는 효과가 있다.As described above, according to the present invention, when the RASP 12 starts in the electronic switchboard, the RASP 12 quickly loads data necessary for the operation from its first storage 22 to the RASP ( The normal starting operation of 12) is effective.
