Product Description

Course Overview

The growing trends in mobile broadband have created a world of opportunities and opened up new challenges, and mobile broadband tests for the enhancement of communication services, such as voice, which are expected to generate 10 billion dollar revenue by 2020 for LTE/HSPA Networks. While LTE networks deliver mobile broadband services with greater data capacity and lower latency, the globally interoperable IP-based voice and video calling services for LTE, known as VoLTE, has enabled development of new innovative communication services like evolved HD voice, audio/video sharing within a call and video communication over IP networks.

This course provides deep insight to all aspects of Voice over LTE (VoLTE) including VoLTE Fundamentals, Evolved Packet Core (EPC) in conjunction with IP Multimedia Subsystem (IMS) to deliver various services, VoLTE architecture, VoLTE network nodes and VoLTE protocols. Subsequently full end to-end LTE and IMS signalling procedures will be examined, including initial attach and registration, bearer and QoS control and SIP/SDP interaction for various call and non-call related situations. The comprehensive training course investigates the core concepts in VoLTE such as VoLTE interfaces, session handling, media and control, VoLTE frameworks and profiles, VoLTE operational scenarios, QoS, security,charging and roaming.
