A process is proposed for determining the radio reception direction on the downlink
at a radio base station location, comprising a plurality of radio coverage areas,
in a mobile communications network, in which in each area on the downlink radio
signals are radiated by means of a transmitting antenna for reception by at least
one mobile communications terminal. For the determination of the radio reception
direction, at least the reception levels of the radio signals radiated by a first
and a second of the transmitting antennae are measured by the relevant mobile communications
terminal. From the two measured reception levels, a ratio value is formed which
is independent of the prevailing radio propagation conditions, and this ratio value
is used to effect an estimation of azimuthal angles for the radio reception direction
to be determined. The invention can thus be implemented in any individual radio
base station location, it being unnecessary for there to be contact with a plurality
of radio base stations. The calculation of a ratio value serves to eliminate influences
which can arise from changing radio propagation conditions. In this way a reliable
estimation of the azimuthal angles and determination of the radio reception direction
is possible. This is independent of the prevailing radio propagation conditions.
