摘要： A method for providing service is provided. A network slice management system of an operator receives a service request message sent by a control device of a third-party service provider. The service request message is used to request the network slice management system to provide a service, and the service request message carries a service requirement. The network slice management system creates a network slice instance based on the service requirement. The network slice instance is used to provide the requested service. The network slice management system sends a notification message to the control device. The notification message carries an identity of the network slice instance.
