QoS and QoE of Advanced Mobile Networks

Course Overview:

The increasing uptake of Internet of Things (IoT), Big data and cloud-based services introduces a new set of requirements for network performance. Furthermore, the evolution of mobile networks towards an all-IP 4G LTE, VoLTE and 5G introduces new challenges for traditional voice and data services. It is critical for operators to guarantee minimum levels of performance. Therefore, operators need to understand and manage both quality and performance of the services to fulfill the technical quality of service (QoS) as well as the quality of experience (QoE) level.

QoE is directly related to QoS. Therefore, one can map the objective QoS measurements (e.g. delay, packet loss and jitter) into the user’s perception QoE, through an appropriate set of tools and processes. QoS is defined as the capability of the communication network to provide a service at an assured service level. QoE basically depends on customer satisfaction in terms of usability, accessibility, and integrity of the service. QoE, however, is not limited to the technical performance of the network; there are also non-technical aspects, which influence the user perception and satisfaction.

In LTE Network, QoS is implemented between UE and PDN Gateway and is applied to a set of bearers. VoLTE QoS covers all the QoS and QoE features in LTE and LTE-A to support VoLTE. One of the major challenges associated with Voice over LTE (VoLTE) is defining the features of the Quality of Service (QoS) for the LTE RAN, EPC and IMS.

VoLTE QoS covers how LTE networks support end-to-end QoS for different IP-based services such as voice, video, multimedia messaging, and gaming. QoS in LTE Radio, EPC, LTE Backhaul and Core Network, PCC (Policy and Charging Control), EPS Bearers, policy, QCI for voice and video applications are covered. Voice over LTE will play a key part in determining a subscriber’s Quality of Experience (QoE) on a LTE/EPC/IMS network.

Pre-Requisites for Participants:

The audience for this course is regulators, telecommunications personnel who need a strong background about the LTE, LTE-A, VoLTE, VoIP, IMS, 5G technologies and mechanisms. It is a pre-requisite for the personnel in charge of the regulation, configuration, monitoring of a 4G, 5G network. The operations and maintenance folks will get an introduction to LTE and how 4G, 5G work and function overall.

Who Should Attend?

All regulators, engineers, technicians and Managers in 4G, 5G, GSM, UMTS, Wi-Fi, LTE technology background.
