Roaming and Interworking
Roaming and interworking covers the signaling, charging-record and messaging functions that let subscribers use partner networks and let IMS, legacy and application domains exchange messages.
The challenge
- Roaming signaling across SS7, Diameter and 5G
- Settlement records and disputes
- SMS continuity for VoLTE and VoNR subscribers
