The invention relates to a method of improving the quality of a radio connection (170) in a cellular radio network. Relevant for the invention, the cellular radio network includes a base station system (126) and a subscriber terminal (150). A bidirectional radio connection (170) using a directional antenna beam (304) is provided between the base station system (126) and the subscriber terminal (150). In the method, in the base station system (126) an angle of incidence (302) of the directional antenna beam (304) is formed on the basis of a received radio signal (170A) transmitted by the subscriber terminal (150). The base station system (126) transmits a radio signal (170B) to the subscriber terminal (150) in the direction of an angle of departure (308) formed on the basis of the angle of incidence (302). In accordance with the invention, a ratio is formed for the imbalance between the downlink and uplink traffics. The processing of the directional antenna beam (304) of the radio signal (170A, 170B) is controlled on the basis of the formed ratio.

1. A method of improving the quality of a radio connection in a cellular radio network including a base station system, a subscriber terminal, and a bi-directional radio connection between the base station system and the subscriber terminal using a directional antenna beam, the method comprising:receiving, by the base system, uplink traffic of the bi-directional radio connection transmitted by the subscriber terminal; transmitting, by the base station system, downlink traffic of the bi-directional radio connection to the subscriber terminal; forming a ratio for imbalance between the downlink traffic and the uplink traffic; and controlling processing of the directional antenna beam on a basis of the ratio.
