A method for detecting a signal propagation time between a mobile radio
terminal and a base station in a mobile radio network in a mobile radio
terminal, particularly for the purpose of localizing the mobile radio
terminal inserts a propagation time detection information item into a
channel request message in order to signal to the base station that no
channel reservation is necessary, and that only the propagation time
detection needs to be carried out, so as to achieve significantly reduced
loading of network resources
