Abstract:
Method for use in a mobile telecommunications system having a plurality of radio access networks (RANs) accessible by mobile stations in their vicinity, said RANs connected to a core network of said mobile telecommunications system, wherein each of said RANs allocates capacity in response to demand for capacity from said mobile stations in their vicinity, said method comprising the steps of:each RAN allocating, for each connection to an associated mobile station, a guaranteed capacity minimum bitrate as well as a non-guaranteed maximum bitrate and communicating said guaranteed bitrate and said non-guaranteed bitrate to said associated mobile station along with an error rate threshold; and each associated mobile station determining an error rate, comparing said error rate to said error rate threshold, and freely using a bitrate between said minimum bitrate and said maximum bitrate for so long as said error rate does not exceed said error rate threshold, but in the event said error rate exceeds said error rate threshold, using a reduced bitrate until said connection is terminated or said error rate no longer exceeds said error rate threshold and again freely using a bitrate between said minimum bitrate and said maximum bitrate beginning a random time period after said error rate no longer exceeds said error rate threshold.
