ABSTRACT:
A system and method that enables session-based and non-session-based application services to be controlled and managed within the IMS/NGN architecture. The IMS/NGN architecture includes a service layer and a transport layer. IMS service control functions are implemented within the service layer, and RACF and transport functions are implemented within the transport layer. The transport functions include access and core network functions, which have corresponding QoS resources. The access or core network function includes an application service control function (ASCF), which includes a PD-FE and a functional element for inspecting packet data flows, and identifying and classifying application services associated with the flows. The ASCF is employed to signal the IMS service control functions on behalf of non-session-based application services, and to reserve and allocate the QoS resources needed to support packet data flows associated with the non-session-based services. As a result, service providers can provide users or subscribers of such non-session-based services with guaranteed or differentiated QoS and/or differentiated service plans, thereby allowing charges to be calculated for the non-session-based services and service plans that are commensurate with the value of the respective service or plan.
