METHOD, SYSTEM, BASE STATION AND DATA CARRIER FOR CLASH-FREE SIGNAL TRANSMISSION BETWEEN A BASE STATION AND A NUMBER OF MOBILE DATA CARRIERS

摘要

To enable a method and a system, having at least one base station (B) and/or one data carrier (D1, D2), for transmitting signals (K, C; Al, A2) between the base station (B) and a number of mobile data carriers (D1, D2) operating in the crypto mode or in the plain mode, wherein [a] the base station (B) emits at least one command signal and/or data signal (K, C) that is provided with at least one identifying pattern (P), [b] at least one of the data carriers (Dl, D2) receives the command signal and/or data signal (K, C) emitted by the base station (B) that is provided with the identifying pattern (P), [c] at least one of the data carriers (D1, D2) that receive the command signal and/or data signal (K, C) transmits to the base station (B) a response signal (Al, A2) that is a response to the command signal and/or data signal (K, C), and [d] the base station (B) receives the response signal (A1, A2) transmitted by the data carrier (D1, D2).To be further developed in such a way that the reliable transmission of data is ensured in a simple yet effective manner, it is proposed that the identifying pattern (P) take the form of at least one first identifying pattern (P1) that identifies the crypto mode, for addressing at least one data carrier (Dl) operating in the crypto mode, and take the form of at least one second identifying pattern (P2) that can be distinguished from the first identifying pattern (P1) and that identifies the plain mode, for addressing at least one data carrier (D2) operating in the plain mode.
