Short Description
VoLTE stands for voice over Long-Term Evolution. It is a
combination of LTE and IMS technology which enables
processing of digital packet voice service that is delivered
over IP
VoLTE course covers technical aspects of how voice is
harnessed in LTE Networks by leveraging the IMS solution
.This course would cover comprehensive information of
VoLTE architecture, Standards, protocols, QoS, interfaces,
interworking, SRVCC,T-ADS,Charging and Call flow.
Objective

• Module 04 : PCRF/PCEF in VoLTE solution
• Module 05: Protocols in VoLTE – SIP, Diameter, RTP,
H.248,GTP,NAS
• Module 06 :VoLTE Subscriber Access, Authentication
and Registration procedures
• Module 07: Application server
• Module 08: SR-VCC(Single Radio Voice Call Continuity)
and T-ADS
• Module 09: Charging concepts
