    摘要： The present invention relates to a method for establishing a random access type connection and a subscriber terminal equipment (37 to 38) and a radio system operating in accordance with the method. The subscriber terminal equipment (37 to 38) establishes a connection to several base stations (33 to 36). The base stations (33 to 36) are selected before establishing the connection by deducing the quality of the connection by means of pilot signals and both uplink and downlink interferences. The subscriber terminal equipment (37 to 38) has a connection to several base stations (33 to 36) already at the initial stage of the connection.
