Controlling intelligent network services

The invention relates to a method for controlling intelligent network services and to an intelligent network. An intelligent network comprising service switching points () and at least one service control point (), whereby for one or more call state models there are two or more service logic programs located at the service control point (), the intelligent network being arranged to direct the call state model to a certain detection point or call phase in response to an operation sent by the intelligent network service, wherein at the service switching point at least one operation is defined, for the execution of which the service switching point can select from two or more alternative routes or detection points to which the service switching point can direct the call state model whereby the service control function is arranged to indicate the route or detection point to which the service switching point is to direct the call state model in connection with said sending of an operation.
