Verfahren und Anordnung zum Erzeugen von Zufallszahlen in Telekommunikationsgeräten eines drahtlosen Telekommunikationssystems
摘要
Useful data, e.g. speech data are evaluated and a start value for the random number generator is thus obtained. The start value is transmitted to the random number generator. Radio transmission path data, e.g. field strength values and/or system specific data (e.g. time frame values) can be used together with speech data as the basis of the random number generating process. System information is evaluated as a third random number parameter according to system values. The telephone system is a DECT/GAP specific cordless telecommunication system.
