With the introduction of LTE operators need to look at how the backhauling network, the network domain that connects evolved NodeBs (eNBs) to MME and S/P-GW, is capable of adapting to the new requirements, namely the adoption of a packet infrastructure, without disrupting the existing services. This paper introduces some reference architectures, moving from a pure layer 2 topology to a full layer 3 one, discussing some elements to be considered in the design process of a network. The purpose of this is to support operators in their migration from current architectures to new, packet-based backhaul networks.
Fostering a successful ecosystem for the deployment of LTE/SAE as the next generation mobile network (NGMN) and its related services is a major goal of the NGMN Alliance's Ecosystem Working Group. As part of the working group's findings it identified that one of the important areas for further investigation is that the deployment of NGMN is expected to be an evolution that will see NGMN being deployed alongside existing networks in the form of heterogeneous networks.
The document describes the achievements done through NGMN technical projects, task forces and other activities during 2007 until 2010. Additionally this document includes references to other publications by NGMN that are important to provide an overview of the work achieved.
4G Americas has published a new white paper regarding strategies and policies addressing the vital need for additional spectrum for mobile broadband services. The white paper, Sustaining the Mobile Miracle: A 4G Americas Blueprint for Securing Mobile Broadband Spectrum in this Decade, provides a guide for securing a bright mobile broadband future to serve society's wireless and technology needs.
The document describes a set of requirements to verify to which extend each technology meets the NGMN White Paper requirements in field trials. Additionally this document includes definitions of environmental factors that are important to facilitate a comparison between various technologies.
This document describes use cases, recommendations and solutions to ensure operational efficiency in NGMN networks. The content of this document has been elaborated in the context of NGMN project on Operational Efficiency (P-OPE)
This NGMN white paper presents the problem and opportunities around publishing content and services across mobile operators. It presents existing solutions driven by external SDOs, as well as recommendations.
The Survey is initiated by NGMN Task Force Quality of Service to investigate the current status of QoS utilisation in the industry and the requirements for QoS from the views of different stakeholders. The objective of the task force is to facilitate the industry's leverage of the benefit of QoS capability provided by next generation mobile networks - LTE/EPC networks.
This document is produced by the NGMN Task Force TD-LTE. It provides general technical analysis on LTE TDD/FDD single chipset and summarizes the vendor survey which aims to give requirements and reference to chipset vendors for TDD/FDD single chipset design and implementation. This white paper is part of the document "Technical Achievements 2007 - 2010".
This paper explains how these dependencies impact the user data rates and shows how a file transfer simulation can be used to characterise the variation in data rates.
