LTE Quality of Service

1 Days / 2 Live Online Sessions (0900-1230) / Technical Level: Level 2

Course Code: LT1314

Course Summary

This course concentrates on the two main areas of an LTE network in which Quality of Service (QoS) is applied – the End-to-End EPS Bearer and the underlying Transport Network Layer (TNL). The main QoS concepts are explored as are details of the interworking between LTE QoS and the QoS schemes employed in other network types, such as UMTS, GPRS and the IMS.

Who would benefit

This course is suitable for engineering and technical management staff who require a technical overview of the technologies and techniques employed by 4G LTE networks to define and control the QoS applied to user connections.

Prerequisites

An engineering background with some knowledge of telecommunications technologies and protocols is assumed and previous LTE training would be beneficial, as would knowledge of QoS mechanisms in legacy 2G and 3G networks.

Topic Areas Include

• E-UTRAN architecture and interfaces

• EPS Bearer and PDN Connectivity options and operations

• User plane connection concepts, packet flows, SDFs and Traffic Flow Aggregates

• LTE QoS parameters, QCI, ARP

• QoS parameter representation in LTE signalling protocols

• QoS Management – TFTs and packet filters

• LTE PCC (Policy and Charging Control) mechanisms

• PCC Rules, function and structure

• Interaction between PCC elements and internal and external network nodes

• Mapping LTE QoS to legacy network schemes

• Measuring QoS

• TNL concepts, architecture and QoS mechanisms

• DiffServ, MPLS and Ethernet QoS

• End-to-End QoS Architecture and Operation

• Network node QoS functions

• QoS influence on LTE handovers
