Abstract
A method for controlling a subscriber station operating on a direct mode channel in a mobile radio system. The mobile radio system is one which includes a radio network with at least one base station and subscriber stations, and at least one subscriber database and further, at least one repeater station, which forwards traffic between the at least one base station and the subscriber stations operating on a direct mode channel. In the method, a subscriber station is registered in a radio network via a base station. The subscriber station transmits a detachment message to the base station, and indicates that it is switching to operate on a direct mode channel. In order that the radio network is able to control and communicate with the subscriber station switched to the direct mode channel, the identifier of the repeater station via which repeater station operating on the direct mode channel can be reached by the radio network, is transmitted to the radio network. The identifier of the repeater station is stored in the at least one subscriber database of the radio network.
