The invention relates to a direction-based interface selection method, carried out by a communication control module (8) in a vehicle (1), for establishing and retaining a wireless high-frequency communication connection between a communication interface of a moving vehicle (1) and a communication interface of at least one counterpart station. In this case, position data and an orientation of the vehicle with respect to a global coordinate system are determined. A position data record is determined by at least one counterpart station and the position data (12) contained therein are extracted. A direction vector (13) from the vehicle (1) to the counterpart station is then determined and an assignment to a sectoral radiation characteristic of a transmission apparatus is determined for said vector. This transmission apparatus is then connected to a communication device (7) via a communication position switch (6).
