Field: Digital communication (Electrical engineering)
Classification: CPC H  G | IPC H

Claim 0:
1. A resource allocation device comprising:
one or more processors configured to:
estimate a course of each mobile terminal based on network information about a location of the mobile terminal acquired from a network device;
estimate a probability that each mobile terminal is located in each area at time of prediction;
calculate, for each area, a number of mobile terminals in the area using the probability and determine whether a maximum value of an overcommit ratio for each area calculated based on the number of mobile terminals in the area exceeds an upper limit; and
based on the maximum value of the overcommit ratio being equal to or less than the upper limit, execute allocation or release of resources to a virtual server group located in each area; and
based on the maximum value of the overcommit ratio exceeding the upper limit, refrain from executing allocation or release of the resources to the virtual server group,

wherein the one or more processors are configured to calculate the overcommit ratio by dividing (i) a number of resources to be committed by (ii) a number of existing resources, the number of resources to be committed being obtained by rounding up the number of mobile terminal to a nearest whole value, and the number of existing resources being a number of resources currently allocated to the virtual server group.
