ABSTRACT:
A method and an arrangement for managing packet data transfer in a cellular system such as the Universal Mobile Telecommunications System, UMTS. The decision about the channel used for the transfer of packet data is made based on a channel selection parameter and values of the parameters needed in the decision-making are sent to the mobile station. The parameters are advantageously sent on a common channel such as the BCH or FACH. Parameters sent advantageously include the maximum packet size on the RACH, current RACH load, a threshold value for amount of data in RLC buffers, etc. The parameters may concern all mobile stations, a subset of the mobile stations or one mobile station in the area in which the parameters are sent. The invention minimizes the transfer capacity load associated with signaling and the transfer of packet data can be performed with minimal delays caused by signaling.
