The present invention provides a control method in a communications network, a centralized controller, and a wireless communications network system, where the method includes: generating a to-be-confirmed processing type list according to a service type of a service flow and a data path type template, where the to-be-confirmed processing type list includes all processing function types that may be needed by the service flow; then filtering the to-be-confirmed processing type list, and generating a processing type list, where the processing type list includes processing function types that are essential to the service flow; further, sequentially selecting a working policy and a working parameter for each processing instance, generating a full path policy, and sending the full path policy to an instance of each function node. Therefore, a corresponding service flow path is selected according to a service type corresponding to a different service flow, a network load is balanced, and network resource utilization is improved. |
