ΑΝΑΠΤΥΞΗ ΣΥΣΤΗΜΑΤΟΣ ΑΥΤΟΜΑΤΗΣ ΚΑΤΑΓΡΑΦΗΣ ΚΑΙ ΕΠΕΞΕΡΓΑΣΙΑΣ ΤΗΣ ΣΥΝΔΡΟΜΗΤΙΚΗΣ ΤΗΛΕΦΩΝΙΚΗΣ ΚΙΝΗΣΗΣ

THIS THESIS CONSISTS OF A THEORETICAL PART A CONSTRUCTION PART AND AN APPLICATION PART. IN THE FIRST PART A NEW METHOD OF TELEPHONE TRAFFIC DATA ACQUISITION IS PRESENTED. THE DATA ACQUIRED IS FROM A LARGE NUMBER OF TELEPHONE SUBSCRIBER LINES CONNECTED BY CONVENTIONAL ELECTROMECHANICAL TELEPHONE EXCHANGES. THIS METHOD IS BASED ON THE SCANNING OF A SUBSCRIBER LINE AND ON THE PROCESSING OF EACH CALL PHASE BY PROGRAMMES BASED ON STATISTICAL DATA TAKEN FROM THE CALL PHASE'S TRANSITIONAL STATES. IN THE SECOND PART A LIMITED CONSTRUCTION OF THE ABOVE METHOD IS PRESENTED. A DATA ACQUISITION SYSTEM IS CONSTRUCTED WITH A HIERARCHICAL STRUCTURE WHICH IS CONTROLLED BY MICROPROCESSORS ON A TWO-LEVEL PARALLEL OPERATION. THE LOWER LEVEL IS USED FOR THE SCANNING OF THE SUBSCRIBER LINES AND FOR TEMPORARY DATA RECORDING . THE UPPER LEVEL IS USED FOR THE COMPRESSION AND PERMANENT STORAGE OF THE DATA ON DISKETTE. IN THE THIRD PART THE APPLICATION OF THE METHOD INTO THE GREEK NETWORK AND ITS USEFULNESS IS DESCRIBED. THE TRANSFORMATION OF THE ACQUIRED DATA IN AN ORGANIZED DATA BASE AND A PROCESSING METHOD ON APC IS ALSO DEVELOPED.
