LTE roaming overview HSS PCRF PCRF MME Subscriber Data 4 • Attachment procedure • Authentication procedure • Update location procedure • Subscriber data retrieval procedure • Policy exchange Roaming border Visited network Home network 1 Attach 2 2 Authenticate Authenticate Update Location 3 Policy exchange 5

  5. Diameter is the key roaming protocol Home MNO Visited MNO Home MNO Visited MNO HSS PCRF PCRF MME • S6a Diameter (3GPP TS 23.401) • AAA interface between visited MME and home HSS • Transfers subscription, location and authentication data for authenticating user access to visited EPS • S9 Diameter interface (TS 23.203) • Policy interface between the Home PCRF and Visited PCRF • Transfers QoS policy and charging control information

  6. VoLTE roaming options Visited P-CSCF Visited Services Distributed Policy Control Home Routed PCRF H-PCRF PCRF PCRF V-PCRF eUTRAN eUTRAN eUTRAN eUTRAN • Home routed with data backhaul to home network (existing data model) • Distributed policy control with policy interfaces • Visited P-CSCF with policy control in visited network (selected by GSMA IR.92) • Visited services with IMS core in visited network Home network Visited network 7
