Abstract
A method of creating a network-initiated secondary packet data service instance includes sending a content request for application data from a mobile station to an application function through an access network. The method further includes sending a request for a secondary packet data service instance from the application function to a policy function, and evaluating the request for a secondary packet data service instance and determining one or more operational attributes from the evaluation. The method also includes creating the secondary packet data service instance between the application function to the mobile station by arranging one or more network components as a function of the one or more operational attributes. The method further includes transmitting the application data from the application function to the mobile station via the secondary packet data service instance.
