Abstract
A central control device and a load balancing method thereof are provided. The central control device includes a network interface, a storage and a processor. The network interface is connected to a plurality of base stations and receives a load parameter from each base station. The storage stores the load parameters. The processor is electrically connected to the storage and the network interface. For each base station, the processor calculates a load indication according to the load parameter thereof to determine whether the base station is an overloaded base station based on the load indication, and calculates an offload priority indication according to the load indication, a quantity of off-loadable resources of at least one neighboring base station, a first weighting factor and a second weighting factor. The processor determines an offload order of the overloaded base stations according to the offload priority indications.
