Abstract
A radio communications system includes a radio base station provided with an array antenna. The antenna lobes of the array antenna can be directed onto a terminal with the aid of a generated directional estimate. The directional estimate is based on a signal received from the terminal. A method registers a generated directional estimate together with a terminal recognition character. The directional estimate is read when the radio connection with the terminal changes channel. The antenna lobe is directed on the basis of the direction estimate, immediately communication commences over the new channel. A radio base station is equipped with a database in which the terminal recognition character and the direction estimate are registered.
