## Abstract

A resource management method, a resource management system, and a workload scheduling apparatus for network slicing are provided. In the method resource management, a service request related to an application type of a terminal device is received. A monitoring report of the terminal device is obtained according to the service request. The monitoring result relates to a condition of the radio resource used by the terminal device. A usage situation of a slicing resource is analyzed based on the slicing resource requested by the service request and the monitoring report to predict a predicted arrangement result of the slicing resource. The slicing resource requested by the service result is arranged according to the predicted arrangement result to transmit a corresponding setting configuration to the radio access network. The setting configuration serves to adjust the slicing resource. Accordingly, the request of the service and the current condition are fulfilled.
