The Voice challenge for LTE

LTE is an all-IP mobile network
–
No support for ‘traditional’ CS domain voice

The risk – industry fragmentation

The Solution for Voice over LTE

The Reality – the industry knows where it is going

–
Massive backing from operator and vendor community.
–
‘Migratory
Migratory solutions’
solutions filling the gap between LTE launch and IMS deployment for
some operators.
VoLTE – GSMA PRD IR.92 “IMS Profile for Voice and SMS”
–
UNI Profile defining the minimum mandatory set of requirements for UE and
Network to support for a high
high-quality
quality IMS
IMS-based
based telephony service over LTE.
–
Based on 3GPP Release 8 standards (and some Release 9 e.g. Emergency
call)
Current status of VoLTE
„
„
„
„
VoLTE launched in three networks – SKT, LG U
U+ and Metro PCS
–
Many additional commitments to VoLTE for launch during 2013
Device implementation combines VoLTE with Wideband codec, Video, RCS
In the meantime,
meantime other operators may launch first with CSFB
CSFB.
–
Delays in SR-VCC capability making CSFB a likely first Voice deployment for
many operators.
–
CSFB still viewed as sub-optimal interim solution - improvements in set-up time
for CSFB ongoing.
–
PS handover (VoLTE <->
PS-handover
< > VoHSPA) may prove to be the alternative to CSFB
CSFB.
Everyone
y
is headingg to VoLTE – jjust takingg different ppaths to gget there.

What is joyn
joyn™?
™?
„
„
„
„
joyn is the global consumer facing brand for RCS-e services that will be used by
operators
t
www.joynus.com
Benefits:Benefits:
–
Service Discovery displays the services available to be used for any particular
contact in the user's address book.
–
joyn is interoperable between mobile operators, which enables the end user to
communicate and be connected with anyone.
–
joyn is either available natively in the mobile phone or can be downloaded as
