Patent ID: 8625608

Claim:
A method for controlling a bit-rate of a session between a sender and a receiver in a packet-switched communications system where multiple sessions are set-up via a shared resource, said method performed at a sending device and comprising the steps of: determining a bit-rate range valid for the session, the bit-rate range having an upper limit and a lower limit; receiving a rate adaptation request message from the receiver; comparing a current bit-rate of said session to said bit-rate range; adapting said current bit-rate in accordance with an estimated bit-rate adaptation so that the current bit-rate is reduced more when the current bit-rate is closer to the upper limit of the bit-rate range than when the current bit-rate is closer to the lower limit of the bit-rate range, or so that the current bit-rate is increased more when the current bit-rate is closer to the lower limit of the bit-rate range than when the current bit-rate is closer to the upper limit of the bit-rate range.
