The invention relates to a method for connection establishment and a radio system relaying packet traffic, in which system a terminal (402) is arranged to inform (700) the system network part (400) that it wishes to transmit dat a to the network part; the network part (400) is arranged to receive the messa ge and to allocate a default amount of radio resources to the terminal; the network part (400) is arranged to inform (702) the allocated resources to th e terminal; the terminal (402) is arranged to send a first control message (71 0) to inform the terminal's radio path characteristics to the network part. According to the solution of the invention, when the network part (400) allocates the default amount of radio resources to the terminal (402), the network part is arranged to reserve one or more radio blocks for the terminal's control messages. When the terminal (402) sends the network part information about its radio path characteristics, the terminal is arranged t o inform in the message if there are additional characteristics. In that case, the terminal sends a second control message (712) comprising information abo ut its radio path characteristics.
