Abstract: A technique for controlling data transmission over a connection employing congestion control is provided. The technique comprises two basic aspects: Detecting a decrease of Round Trip Time in respect of the connection, wherein the detection is facilitated by comparing a short-term Round Trip Time average with a long-term Round Trip Time average (302); and, in response to a result of the detection, adjusting the congestion control so as to increase the data transmission rate (304). Particularly, adjusting the congestion control includes enabling a data transmission rate that is (even) higher than what would have been allowed by any conventional, congestion control. In effect, the present technique may ‘push’ the conventional congestion control when it is not increasing the data transmission rate fast enough.

Abstract: A method of reducing buffer overflow in a cellular radio network caused by a transfer of data from a buffer in a first cell to a buffer in a second cell when a handover of mobile equipment from said first cell to said second cell occurs. The method comprises temporarily increasing an amount of temporary buffer space required to handle data transferred from the buffer of the first cell to the buffer of the second cell. In one embodiment of the method, prior to increasing the amount of temporary buffer space, the amount of temporary buffer space required is calculated.
