The invention discloses a resource scheduling method and a resource scheduling device used for solving the problems how to improve the business experience of a user when a resource is provided for a preemptive bearing, and relates to the field of a mobile communication technology. The method comprises the steps of calculating the quantity of resource needed by the preemptive bearing when the preemptive bearing waists for the release of the system resources; performing speed reduction process on the bearing of an accessed system sequentially until the rest of resources of the system meet the quantity of resources needed by the reduction of speed or until the bearings of all accessed system are conducted for speed reduction process, wherein the speed of each bearing after the speed reduction can meet the lowest requirement; and distributing the test of resources of the system to the preemptive bearing when the rest of resources of the system meet the amount of resources needed by the preemptive bearing.
