The invention discloses a method and device for implementing a service-side drive service and an uplink service node. The method comprises the following steps: receiving a notification message from a service capacity module by an uplink service interface module, wherein the notification message carries interface input parameters; acquiring input parameter information by the uplink service interface module in accordance with the interface input parameters; and scheduling an interface of a service execution module by the uplink service interface module so as to adopt the input parameter information, uplink service identifications and uplink service method identifications to execute service process instances. According to the technical scheme provided by the invention, the demand of simplifying a service process can be met, thus improving the user experience.
