Agenda

Drivers for 4G roaming The Value of Voice over LTE VoLTE/IMS interworking and

roaming Disruptive multimedia – Carrier

WebRTC Deploying 4G data roaming


Drivers for 4G Voice and Data Roaming

But… subscribers are trained to switch off their mobile data

The value of Voice Over LTE

The value of VoLTE HD Voice - better QoS Higher MOS: ~3.8 vs. ~3.4 Skype Faster Connect: 2.9 sec vs. 5 sec

for 3G Battery Life: 56-94% longer than

Skype

VoLTE/IMS Roaming Architectures

S8HR Comparable to existing mobile data roaming

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

• Local number mapping provisioning in HPMN

Local Breakout RAVEL – Roaming Architecture for Voice Over

IMS with Local Break Out Introduces TRF SIP Signaling and Media sent together over NNI Benefits

Familiar charging model – Reuse of cascade billing techniques

Support for Emergency Services Lawful Intercept Voice fall back support (CS/SRVCC)

Challenges Complexity – variations in UE to core IMS Both networks require IMS OCS interface required between networks

Which approach? Traffic dependent First commercial VoLTE roaming

arrangement April 2015 LG UPlus and KDDI using S8HR

Additional VoLTE roaming trials Docomo, KT, and Verizon using S8HR KPN, China Mobile and iBasis using a

LBO approach.






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

Layer advanced contextual voice services on top of roaming hub
