Abstract:
The method includes recording for introducing subscriber information change and abnormal call to a subscriber, connecting and releasing channel for messaging. The method comprises the steps of: (A) checking the state of line and maintaining the line empty for preventing blocking when a channel connection request is received; (B) discriminating the types of requested service and requesting line connection to a space switch; (C) sending connecting complete signal to a global service control block; and (D) releasing line using the space switch when a release request signal is transmitted from the global service control block.
Abstract:
The method provides a various services, efficiently controls the traffic quantity , and gives a high fidelity services. The method employs a man machine processor (MMP:4A), a central control subsystem (CCS:1A) which contains a software subsystem (MMS:9A), an operation maintenance processor (OMP:5A), an interconnect network subsystem (INS:2A) which contains a software subsystem (NTS:10A), a control software block (RCO:12A), a number translation software block (NTR:13A), a number translation processor (NTP:6A), and an access switching subsystem (ASS:3A) which contains an access switching processor (ASP:7A).
Abstract:
The method for generating processor load data suitable to relations registered to a data administration system and for generating data to be reference to distributed data base system. The method comprises the steps of: (A) verifying input station data necessary to operate an exchange; (B) sending error message when errors are detected from the input station data; (C) generating relation data by processor units and generating object files; (D) generating tuple data and constructing files by processor units; (E) generating relation data; (F) generating relation search data; and (F) generating process or load data by linking results of the step (A)-(E).
Abstract:
The method for using user's own program directly without recompiling regardless DB version comprises steps: (a) generating list files corresponding to the reference and request DB versions when the synchronisation request for the relation number of the new generated DB version by the operator is received; (b) comparing each relation numbers and names of the requested and the reference DB versions; (c) if the compared numbers are different, the reference relation number is allocated to the requested relation number, but repeating the (b) step as much as the relation number of the requested DB version; (d) after comparing process is ended, the relation number of the requested DB version is synchronized to the relation number of the reference DB version.
Abstract:
The method is for accessing a data base with minimized time and in real time by using the physical address of the data base. It is composed of the stages of: generating the physical data structure; generating the information needed for controlling; generating the information needed for searching physical address; allocating the physical starting address of relation; and searching attributes directly from data base.
Abstract:
본 발명의 목적은 교환기의 호 서비스 신뢰도를 높이기 위해서 대규모 전전자 교환기에 데이타 파손, 프로그램 오류 그리고 부하 정도에 따른 처리순서 불일치등으로 인한 통화 부족현상과 통화중 절단현상을 최소화할 수 있는 통화로 제어방법을 제공하는데 있다. 상기의 목적을 달성하기 위하여 본 발명은, 공간스위치(SSW)를 내장한 연결망 서브시스팀(INS)과, 상기 연결망 시스팀에 연결되어 타임스위치(TSW)를 내장한 다수의 교환서브시스팀(ASS)으로 구성된 통화로계를 갖고 통화로를 제어하는 전전자 교환기에 있어서, 발신가입자와 착신 가입자의 통화로 채널을 배정하는 제1단계, 발신 가입자의 타임스위치를 연결하고 착신 가입자의 타임 스위치를 연결하여 통화로를 연결하는 제2단계, 발신 가입자의 타임 스위치를 절단하고 착신 가입자의 타임 스위치를 절단하여 통화로를 절단하는 제3단계, 발신가입자와 착신 가입자의 통화로 채널을 해제하는 제4단계로 이루어진다.
