Abstract:
1. A method for communication of information in a telecommunication system having at least one fixed Abis interface and one radio interface, wherein each interface has flexible capacities for a plurality of connections having eligible higher or lower bandwidths, wherein the information sent on the connections are coded at eligible code rates, wherein the fixed Abis interface connects a base station controller with a base transceiver station, wherein the information is coded according to Adaptive Multi Rate (AMR) codecs defining half rate or full rate communications between the base station controller and the base transceiver station, and wherein the base transceiver station has half rate or full rate communications for the information on the radio interface with a mobile station, said method comprising the steps of: estimating the current load on the fixed Abis interface; and, if the estimated current load is above a certain threshold, switching communications on the Abis interface from the full rate to the half rate while keeping the full rate communications on the radio interface, wherein when the estimated current load is above the certain threshold this indicates that the Abis interface is currently overloaded and then the subsequent switching communications on the Abis interface from the full rate to the half rate results in the Abis interface being even more overloaded than before the switching of the communications but the overload is compensated for on the radio interface.
