Abstract

A találmány tárgya helymeghatározó rendszer digitálistelefonhálózatokhoz, helymeghatározó rendszert tartalmazó digitálistelefonhálózat, kézibeszélő ilyen digitális telefonhálózathoz éseljárás mobil vevőkészülék helyének meghatározására. A találmányszerinti helymeghatározó rendszer legalább két, adóegységet istartalmazó digitális telefonhálózathoz tartozó vevőegységet tartalmaz,amelyek közül az első ismert helyen tartózkodik, a második pedig olyanmobil vevőegység, amelynek a helyét meg kell határozni, továbbá arendszer adásjeleinek legalább egy része előre meghatározott vagyismétlődő értékeket tartalmaz. Az egyes vevőegységek a következőelemeket tartalmazzák: referenciaóra; az egyes vevőegységekben areferenciaórához szinkronizált referenciajelet előállító eszköz, amelyreferenciajel formátuma hasonló az adásjelek formátumához, és ezáltala referenciajel egy része megegyezik a vett jel előre meghatározottvagy ismétlődő értékeket tartalmazó részével; az egyes vevőegységekbena beérkező adásjelet és a beérkező referenciajelet összehasonlító ésazok egymáshoz viszonyított késleltetését meghatározó eszköz, amely akét vevőegységben az egymásnak megfelelő, beérkező jelek közöttiidőbeli késleltetés alapján határozza meg a második vevőegység helyét.A találmány szerinti digitális telefonhálózat a találmány szerintihelymeghatározó rendszert tartalmazza. A találmány szerinti digitálistelefonhálózatban alkalmazható kézibeszélő a különböző adóegységektőlkapott adásjelek egymáshoz viszonyított időbeli késleltetéseit azokegymással történő összehasonlítása révén mérő eszközt, valamint akézibeszélő helyének meghatározása érdekében a viszonylagos időbelikésleltetéseket reprezentáló adatokat továbbító eszközt tartalmaz. Atalálmány szerinti, mobil vevőegység helyének meghatározására szolgálóeljárás helymeghatározó rendszerrel ellátott, legalább kétvevőegységet tartalmazó digitális telefonhálózatban alkalmazható, aholaz egyik vevőegység ismert helyen tartózkodó vevőegység, a másikvevőegység pedig mobil vevőegység. Az eljárás is a találmány részétképezi. Ó
