Abstract:
A method of establishing a radio link between at least two network subscribers of a digital relay radio network, wherein an individual position identification is assigned to each of the individual network subscribers so that the position of all network subscribers may be determined relative to each other, and wherein each network subscriber knows its own position identification as well as the position identifications of a source subscriber (SS) and a destination subscriber (DS), and with each network subscriber including a transmitter, and comprising the steps ofaddressing a mobile network subscriber (TS) with a radio signal from the source subscriber (SS) or a previous network subscriber (PT), comparing the position identification of the addressed network subscriber (TS) with the position identification of the source subscriber (SS) or the previous network subscriber (PT), and with the position identification of the destination subscriber (DS), and determining whether the position identification of the addressed subscriber (TS) is closer to the position identification of the destination subscriber (DS) than to the position identification of the source subscriber (SS) or the previous subscriber (PT), and if so then causing the addressed subscriber (TS) to retransmit the radio signal from the source subscriber (SS) or the previous subscriber (PT), and if otherwise causing no retransmission from the addressed subscriber (TS) but a continuation of the transmission via the source subscriber (SS) or the previous subscriber (PT).
