Abstract
In a method of controlling the power at which an access packet is transmitted by a mobile on an access channel to a base transceiver station of a mobile radio system, the base transceiver station transmitting a broadcast channel regularly, the base transceiver station transmits on the broadcast channel a power indication representing the transmit power of the broadcast channel. At the mobile the power received on the broadcast channel is measured and the measured power is compared with the transmit power indicated by the transmit power indication on the broadcast channel to deduce an estimated propagation loss from the mobile to the base transceiver station. An optimal transmit power for the access packet is determined on the basis of the estimated propagation loss and parameters of the mobile radio system.
