Control of multidirectional antenna structure in a primary station for use in a radio communication network
First Claim
1. A mobile station for use in a communication system including a plurality of base stations, said mobile station comprising:
- a multi-directional controllable antenna structure operable to transmit and receive radio signals;
acquisition means for acquiring data relating to at least one of said base stations from at least one radio signal received by said multi-directional controllable antenna structure;
selection means for, based on the acquired data, conditionally selecting at least an active base station and conditionally selecting at least an alternative base station suitable for becoming active;
calculation means for calculating directions of signals received from the selected base stations;
storage means for storing the calculated directions; and
control means for controlling said multi-directional controllable antenna structure in dependence of the stored directions.

Abstract
A method for controlling a multidirectional antenna structure in a primary station for use in a radio communication networks comprising a plurality of secondary stations. This method involves an acquisition step of acquiring data relating to secondary stations, a selection step of selecting, based on acquired data, an active secondary station and alternative secondary stations suitable for becoming active, a calculation step of calculating the directions of signals received from the selected secondary stations, a storage step of storing the calculated directions, and a control step of controlling said antenna structure depending on stored directions.
