METHOD FOR CONNECTION ESTABLISHMENT IN A RADIO SYSTEM RELAYING PACKET-SWITCHED TRAFFIC AND RADIO SYSTEM

摘要

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 data to the network part; the network part (400) is arranged to receive the message 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 the terminal; the terminal (402) is arranged to send a first control message (710) 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 to inform in the message if there are additional characteristics. In that case, the terminal sends a second control message (712) comprising information about its radio path characteristics.
