VoLTE introduction requires full interoperability
with the external world:
Media
Gateway

Other IMS and non-IMS VoIP domains

PSTN/PLMN
LTE
IPv4/IPv6
Border
Gateway
SBC
TDM
Diameter
Routing
System
NetMatch products have been designed for smooth
all-IP transformation, allowing:

migration from TDM to IP networks

migration from 2G/3G mobile networks towards LTE
and VoLTE

Delivery of voice and HD video services
Conclusions
 LTE constitute a powerful and effective tool for overcoming the
“digital divide” in rural areas
 Pre-IMS deployments can effectively accelerate VoLTE delivery
to fixed end-users, when specific features support (e.g.: PATS
requirements) is mandatory , thus enriching the SP’s offer and
providing a “zero impact” on user experience for legacy services
 VoLTE architecture is perfectly suitable for exceeding the
telephony experience and delivering HD Video services across
fixed and mobile…
