4G & 5G Roaming Scenarios & Procedures course description This course is designed to explain the roaming procedures of modern mobile networks, based on the GSMA roaming specification the course explains all scenarios where a mobile subscriber may find themselves whilst visiting a preferred mobile network partner. Interconnection between MNOs and the use of GRX & IPX as an interworking process. The course will work through the registration & authentication procedure, download of the user profile, the APN configuration & DIAMETER process to verify user authenticity. VoLTE roaming and IMS registration procedures for voice support & SMS delivery will be discussed and explained.
