arrangements Leverages core IMS of Home Network Push towards QoS based charging
Higher QCI values (1,2) for Voice and Video Benefits
Fast time to market Less complexity Enables VPLMN w/o IMS support VoLTE roamers
Challenges Emergency calling Geo local calling

IPX value proposition Any-to-any connectivity
Interoperability between operators deploying different roaming methods
Build on existing IP Proxy with P-CSCF and TRF functionality
Enable faster time to market Enable VoLTE roaming for operators without IMS
core Accelerate revenues and monetization of 4G Outsourcing and hosted options for customers
Regional breakout in addition to local breakout Offload backhaul, improve latency on the more
complex call scenarios TDM interworking and transcoding heavy lifting
