The invention relates to a method for connection establishment and a radio
system relaying packet traffic. A terminal informs the system that it
wishes to transmit data. The network part receives the message and
allocates default radio resources and informs the allocated resources to
the terminal. The terminal sends a first control message to inform the
terminal's radio path characteristics. According to the solution of the
invention, when allocating the default amount of radio resources to the
terminal, the network part is arranged to reserve one or more radio blocks
for the terminal's control messages. When the terminal sends the network
part information about its radio path characteristics, it is arranged to
inform in the message if there are additional characteristics. In that
case, the terminal sends a second control message comprising information
about its radio path characteristics.
