Abstract:
A channel allocation method in a cellular radio network that includes at least one base transceiver station and at least one subscriber terminal connected to the base transceiver station over a bi-directional radio link wherein:in the channel allocation decision, an impact of a possible channel allocation on an interference level of the cellular radio network is taken into account; a prediction on the impact of a possible channel allocation on the interference level of the cellular network is made based on the received power level (RxLevs) of the serving cell, the received power level (RxLevi) of the adjacent cells and the signal qualities (RxQuali) of the adjacent cells; a probability P=Ps*Pn, is calculated for channel allocation, where variable Ps is dependent on the received power level (RxLevs) of the serving cell and variable Pn is dependent on the received power level (RxLevi) of the adjacent cells and the signal qualities (RxQuali) of the adjacent cells; variable Pn=II Pni, where Pni represents the probability on base transceiver station i and where variable Pni obtains values between 0 and 1; and variable Pni is calculated linearly according to equation Pni=a*RxLevi+b, where variable a is dependent on signal quality (RxQuali) and variable b is dependent on signal quality (RxQuali).
