This Technical Report defines key issues and studies PCEF/TDF charging solutions for the network usage of services and applications when TDF performs application detection and control. Both online and offline charging aspects will be considered. The work will be based on the Rel-11 Policy and charging control architecture, including the specification for application detection and control and the corresponding TDF functionality definition, as defined in TS 23.203
Based on the technical analysis, any needed enhancements/updates to 3GPP functions and interfaces will be identified.
The agreed solutions will be evaluated for subsequent normative specification.
