Abstract:
1. A method for assigning transmission rates, for an uplink packet data channel, to a mobile terminal in a radio telecommunications network comprising a radio base station, comprising the steps of: said radio base station receiving at least a first rate request from said mobile terminal, said radio base station sending at least a first grant message to said mobile terminal assigning a first transmission rate for uplink packet data transmission, said radio base station receiving at least a second rate request from said mobile terminal, said radio base station measuring a utilized transmission rate for said packet data transmission from said mobile terminal to said radio base station, said radio base station determining whether a condition exists, wherein the step of determining whether the condition exists comprises determining whether said measured transmission rate is lower than a first specified fraction of said assigned first transmission rate, and said radio base station sending to said mobile terminal a new grant message repeating said first transmission rate in response to determining that the condition exists, wherein said new grant message is sent to said mobile terminal without first receiving a rate request from said mobile terminal.
