Abstract
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.
