Abstract

A találmány tárgya kommunikációs rendszer, időosztásos többszöröshozzáférésű (TDMA) adatátviteli eljárás alkalmazásával, amelyben azadatokat keretekben továbbítják, amely keretek több időrésre vannakfelosztva és egy keret kezdete több vezérlőidőrésből és az ezt követőadat-időrésekből áll, ahol egy adott felhasználóhoz egy meghatározottvezérlőidőrést rendelnek hozzá, és ahol minden egyes időréshez egyelső, maghatározott biztonsági időt rendelünk, és a találmány szerintegy keretet a következő lépésekkel hoznak létre: a keret elsőelfoglalt vezérlőidőrésének időzítését az előző keret utolsóvezérlőidőrésének időzítése alapján határozzák meg; minden egyestovábbi elfoglalt időrés időzítését a kereten belül az azonos keretbenutolsóként elfoglalt vezérlőidőrés időzítése alapján határozzák meg; akereten belül az elfoglalt vezérlőidőrések időzítését az azonoskeretben levő utolsó elfoglalt vezérlőidőrés időzítése alapjánhatároznak meg, és a kerethez egy második meghatározott biztonságiidőt rendelnek, amely biztonsági időt a keret végére helyezik, amásodik biztonsági időt az első biztonsági időhöz képes megnyújtják.
