Next Generation Mobile Networks (NGMN) framework paper about integrated QoS management. Important to understand by those who need to plan/design QoS for LTE deployments.
Short introduction and purpose of document
The deployment of LTE networks is a key step in fulfilling the promise of high broadband anywhere and being connected all the time. With the increasing separation between peak and average bitrates, the use of advanced QoS management mechanisms becomes increasingly necessary in order to deploy cost-effective backhaul networks and avoid over-dimensioning.
A key element of better QoS management is a better integration of service and transport mechanisms and performance measurements. RAN nodes, being necessary points of passage, could be the ideal link between these two levels. However, no standard approach currently exists, and the mechanisms proposed by vendors are proprietary and opaque.
NGMN can provide a framework for defining and supporting the development of integrated QoS management solutions in three ways: clarifying their definition, facilitating interoperability and their further integration with transport-level mechanisms.
This will increase the operational agility of operators, enable vendors to expose their support of advanced features and improve the overall capacity of the network to handle high-value traffic.The current timing (with developing alternatives but no generic frame of reference) is right for NGMN to help establish a consensus on the definition and characteristics of these solutions.
This framework is organised into two parts;
-Part one is about service flow classification and the associated inter-layer classes of service alignment and,
-Part two is about investigating potential integrated service/transport layer QoS mechanisms.
This document covers part one of this framework.
