The invention provides a computation resource distribution method and a computation resource distribution system based on a processor in a communication system. The method comprises the steps of S1, acquiring a business set to be distributed; S2, performing permutation and combination on available computation resource blocks according to a predetermined strategy based on a computation resource mapping division scheme, thus acquiring different computation resource block combinations; and S3, distributing the computation resource block combinations to businesses in the business set to be distributed. The step S3 comprises the sub-steps of distributing computation resources to the single business k, distributing the resources to the plurality of businesses according to a priority sequence, or distributing the resources to a business queue after the plurality of businesses are permuted and combined, and selecting a distributing scheme with the maximal computation resource utilization rate to distribute the computation resources. According to the method and the system provided by the invention, the utilization rate of the computation resources in the communication system can be effectively enhanced, and relatively low complexity is provided.
