The present invention relates to a connection establishment method and a radio system. When a base station (11) detects a preamble (20) from a subscriber terminal equipment (13), the power adjustment of a closed loop is started for controlling the transmission power of the subscriber terminal equipment (13). Signals (15) of the base station (11) and the subscriber terminal equipment (13) are synchronized and the subscriber terminal equipment (13) sends a randomly selected identifier. The identifier determines a transit channel to which the subscriber terminal equipment (13) suggests to move. The base station (11) may change the suggested transit channel and echo the identifier back to the subscriber terminal equipment (13), and the base station (11) and the subscriber terminal equipment (13) communicate on the transit channel from which they move to a traffic channel. The inventive method accelerates connection establishment.

[ What is claimed is:] [1.] A connection establishment method in a radio system including at least one base station and a plurality of subscriber equipment, the method comprising:multiplying system signals, to be sent, by spreading codes;synchronizing a connection from a base station of the at least one base station to a subscriber terminal equipment of the plurality of subscriber terminal equipment;receiving, by the subscriber terminal equipment, control data of the radio system from the base station;sending of an access signal by the subscriber terminal equipment to the base station on an access channel, wherein:when establishing a connection, the subscriber terminal equipment transmits on the access channel essentially at most:a preamble including sync data of a spreading code,an identifier including at least data on the subscriber terminal equipment, anda timing sync portion including a synchronization word, at least the identifier being interpreted by using the synchronization word, wherein:the preamble is sent as long as the base station detects the preamble and a power adjustment of a closed loop is started to keep transmission power of the subscriber terminal correct, starting of the power adjustment of the closed loop informing the subscriber terminal that reception of the preamble of the access signal is successful.
