Study on enhanced IP Multimedia Subsystem (IMS) to 5GC integration Phase 2; CT WG4 aspects
The aim of this Technical Report is to study and specify potential enhancements to the IMS architecture to enable IMS FE to integrate with the 5GC network functions to enable IMS applications to directly leverage the features and capabilities of 5GC.
The specific capabilities of 5GC included in this study:
- How can IMS utilize services provided by 5GC NFs other than PCF, such as HSS/UDM and AMF.
- How can localized routing of IMS media and signalling traffic be leveraged.
