Abstract:
1. A scheduler which allocates radio resources to mobile terminals in a radio mobile communication system, said scheduler comprising: a calculator which calculates, for each of the mobile terminals which are the objects of scheduling, an evaluation value relating to priority of allocation of radio resources by a predetermined evaluation formula including radio quality information relating to radio quality between a base station and the mobile terminal; a controller which controls the evaluation value so that the priority of allocating a radio resource to a mobile terminal, whose instantaneous radio quality is determined to be lower than a required radio quality, becomes lower than the priority of allocating a radio resource to a mobile terminal, whose instantaneous radio quality is determined to be equal to or higher than the required radio quality; and an evaluation value distribution controller which gives, to the evaluation value formula, a parameter for controlling the region of the maximum value and the dispersion as distribution characteristics of the evaluation value with respect to the instantaneous radio quality, wherein said evaluation value distribution controller controls the distribution characteristics of the evaluation value with respect to the instantaneous radio quality, corresponding to the statistical distribution of the instantaneous radio quality with respect to the mobile terminal of the radio mobile communication system.
