Evolved Packet Core (EPC) enhancements to support interworking with data application providers; Stage 2
This Technical Report describes solutions for interworking between mobile operators and data application providers. The solutions developed will describe a framework for authentication, authorization, policy and charging for various interworking scenarios.
Solutions developed as part of this work item will cover the following different relationships between mobile operators and data application providers for both roaming and non-roaming cases when
- mobile operator owns all the application layer entities;
- mobile operator does not own all the application layer entities.
The technical report will investigate charging, policy and group addressing capabilities for interworking between mobile operators and data application providers. Updates to 3GPP functions and interfaces will be specified for solutions based on IMS and/or EPC.
On-going work for authentication and other aspects in other 3GPP work items will not be duplicated. It will be investigated whether changes to 3GPP specifications are needed and if so which ones. The work item will focus on impacts to IMS and EPC.
