This course covers the principles and all other aspects of international and LTE roaming. Participants will learn about roaming in 2G and 3G core networks, SS7 signaling basics and routing, call establishment protocols such as MAP and ISUP and various LTE roaming architecture models as specified by the GSMA. 

Participants will also learn different roaming interfaces such as SIP and diameter protocols, the importance of DEA/DRA and IPX peering, the cost structure of the various roaming services that would help maximize roaming margins. They will gain knowledge on steering of roaming and IoT discount negotiation, which are important tools in this field.
