Quality of Service

Introduction

New Networking technologies, Services and Applications are all arriving on the market, each with an aim to deliver a Quality of Service (QoS) that is equal to or better than the legacy equipment.

Service providers and network operators have trusted brands, the maintenance of which is critical to their business. The challenge is to make new technology work in a way that meets customer expectations for quality, availability and reliability, while still offering network operators the flexibility needed to adapt quickly to new technology.

Quality of Service (QoS) parameters are a key factor in the roll-out of new technology. ETSI works on several QoS specifications and has been particularly active in Interoperability events on speech quality.

QoS parameters are increasing in importance as networks become interconnected and a large number of operators and providers interact to deliver communications.

Our Role & Activities

3GPP™ Technical Specification Group SA2 covers Quality of Service requirements for access to both packet and circuit switched GSM and 3G networks.

ETSI E2NA and NTECH

E2NA and NTEC Technical Bodies are responsible for fixed networks and for migration from switched circuit networks to packet-based networks with an architecture that can serve in both.

E2NA is responsible for QoS studies in Next Generation Networks

ETSI STQ

STQ is ETSI's technical committee for Speech and multimedia Transmission Quality. Upcoming new services and technologies hold new challenges for end-to-end media quality as perceived by the user and for Quality of Experience (QoE), both subjects being addressed by STQ. New interests for future study include:

  • Impact of poor transmission quality on intelligibility
  • e-Inclusion for people with disabilities and for ageing
  • Loudness vs. Loudness Ratings
  • Concepts of 'net neutrality' & ‘differentiated traffic management' and their potential impact on QoS as perceived by the user 
  • Synchronization and interworking in packet based networks 

New NGN services in conjunction with the use of smartphones require new QoS measurement methods, reference data and load profiles in order to guarantee the quality of new services. These encompass web browsing, data transfer, video streaming, video live traffic, video sharing and LTE RCS location services.
