LTE and VoLTE Fundamentals

What you'll learn
  • Key concepts of LTE and VoLTE

  • Basic understanding of wireless networks

This self-paced LTE and VoLTE learning program from Dr. Nishith Tripathi (Samsung Research America) and Prof. Jeff Reed (Virginia Tech) provides a concise technical overview of LTE (Long Term Evolution) and VoLTE (Voice over LTE) through a series of video lectures. These lectures are based on the world’s first 5G multimedia book: “5G Cellular Communications- Journey and Destination.”
Section 1- Introduction to LTE and Network Architecture. Learn about how the wireless networks evolve from a third-generation (3G) cellular technology to a 4G LTE. Also, find out what entities exist in an LTE network.
Lecture 1: LTE Network Architecture.
An overall network architecture of LTE is described with the job functions of major network nodes or elements. Both the radio network and the core network are covered.
Section 2- Information Transfer in LTE. Ever wondered how a signaling message or user traffic such as an IP packet travels through a wireless network? This section explains the transfer of such information!
Lecture 2: LTE Radio Interface Protocol Stack. The air interface between the UE and the LTE Base Station (i.e., eNdoeB or eNB) follows the rules of engagement defined by the radio interface protocol stack. This lecture explains the roles of the protocols such as RRC, PDCP, RLC, MAC, and PHY.
Lecture 3: LTE Attach Procedure. Before you and I can exchange traffic such as a video or a photo using our smartphones, the smartphones need to meet certain prerequisites. The Attach procedure is one such prerequisite, where operations such as mutual authentication and default bearer setup occur.
Lecture 4: Data Transfer in LTE. This lecture explains how data transfer occurs between the device and the network in the downlink and the uplink.

Section 3- Mobility Management in LTE. An LTE UE may be in a Connected Mode or an Idle Mode. This section describes how handover is managed in the Connected Mode and how cell reselection, paging, and Tracking Area Updates are carried in the Idle Mode.
Lecture 5: Handover in LTE. This lecture illustrates the process of handover in LTE, where the network controls the UE configuration for measurements and controls the UE mobility.
Lecture 6: Idle Mode Activities. A UE without a dedicated radio connection operates in the idle mode. This lecture explains the idle mode operations such as cell reselection, paging, and Tracking Area Updates.

Session 4- VoLTE Fundamentals. This section discusses the basics of how a voice service is supported using an LTE network.
Lecture 7: Key Concepts of VoLTE. The LTE network supports voice services using the help of an IMS (IP Multimedia Subsystem) network. This lecture defines VoLTE and provides an overview of fundamental concepts of VoLTE including registration and call setup.
