Patent ID: 7710890

Claim:
A method for detecting a signal propagation time between a mobile radio terminal and a base station for the purpose of localizing the mobile radio terminal, the method comprising the steps of: generating a channel request message in the mobile radio terminal, wherein the channel request message is provided in order to prompt the base station to determine a physical channel for transmitting further messages and to reserve the physical channel in order to set up a connection; transmitting the channel request message to the base station; receiving a channel allocation message from the base station, wherein the channel allocation message comprises: data related to channel parameters of the physical channel reserved in the base station for transmitting further messages in accordance with the channel request message; a signal propagation value for synchronizing the mobile radio terminal to a timeslot pattern in the base station in order to continue connection setup; and inserting a propagation time detection information item into the channel request message at the mobile radio terminal in order to use the channel request message to signal to the base station that only propagation time detection needs to be carried out without reservation of the physical channel.
