This project aims to define requirements and to assess innovative ALL-IP transport solutions facilitating optimum backhauling (including self-backhauling).

 

It comprises a set of project streams:

 

  • Deployment Scenarios and Protocol Stacks (led by Alcatel-Lucent and Nokia Siemens Networks)
  • Backhaul Dimensioning (led by Cambridge Broadband Networks)
  • End-to-End Backhaul QoS (led by Huawei with Cambridge Broadband Networks, NEC, Tellabs)
  • Backhaul Security (led by Alcatel-Lucent)

Main Deliverables

Main deliverables of the project are/will be:

 

  • LTE backhauling deployment scenarios
  • Transport Provisioning for LTE
  • Quality of Service
  • Security
  • Phase/Time Synchronisation


EXECUTIVE WORKSHOP ON DEVICES


Project Leader

Mohammad SHAHBAZ (Lead), KPN/E-Plus


Scope & Objectives

The NGMN Alliance has been carrying out Executive Workshops on Devices since 2007 with the objective to jointly review the next generation device roadmap with NGMN Partners, to identify gaps to vendors' or standards' planning and to agree on action plans. The overall goal is to ensure synchronised availability of end-user devices and network elements. In 2011, the 5th Executive Workshop on Devices will be held.

 

To ensure a solid and structured basis for tracking NGMN milestones for device availability, the workshop is based on a survey carried out prior to each workshop. The results of the survey will be presented and discussed during the Executive Workshop on Devices.



PROJECT QUALITY OF SERVICE (QOS)


Project Leaders

Jinhan SONG (Lead), SK Telecom
Nathalie JOLLIVET (Co-Lead), Orange/FT


Scope & Objectives

The scope of this project is to

 

  • Understand the current status of QoS management capabilities enabled by SDOs and provided by suppliers
     
  • Understand the views toward QoS of industry parties (operators, vendors, 3rd parties)
     
  • Identify potential gaps between requirements for QoS and existing QoS capabilities
     
  • Explore how to implement QoS in networks efficiently with regards to technology and cost perspectives
     
  • Consider ways to solve potential barriers of implementing QoS (technical gaps, regulatory issues, etc.)
     

The objective of this project is to ensure the easy and cost effective implementation of end-to-end Quality of Service in LTE/EPC networks.



TRIAL

Contact: Franck EMMERICH, NGMN Office (office(at)ngmn.org)


Scope & Objectives

NGMN recognises that trial and validation activities are vital to accelerate the development of the NGMN eco system and its services by taking into account the lessons learned from other/previous technologies. Concerted trial initiatives will lead to accelerated development cycles and early time to market.

 

The NGMN Alliance has established a Trial project to accompany, guide and leverage industry activities and initiatives in the field of testing and validation of NGMN candidate technologies.

 

Objectives of the NGMN Trial project: 

  • Set up a framework to enable open collaboration between NGMN Partners and external trial initiatives;
  • Consolidate and evaluate trial results for different NGMN candidate technologies;
  • Provide evidence of key technology capabilities in technical field trials and friendly customer trials;
  • Benchmark technologies  against common NGMN requirements and recommendations (White Paper 3.0).

 

NGMN has not setup or execute trials on its own, but has leveraged existing trial initiatives of NGMN Partners or other industry forums based on an open and transparent collaboration framework. In a first stage, the NGMN Trial project generated common trial requirements and test cases and provides these to the respective trial initiatives for consideration to get results in a consistent manner. In the second stage, the Trial project accumulated specific trial results delivered from those initiatives and evaluated these trial results against the NGMN requirements and recommendations.


Working Principle


The NGMN Trial project took into consideration all NGMN candidate technologies. The LTE/SAE trials were driven and executed by the so-called LTE/SAE Trial Initiative (LSTI, www.lstiforum.org). The development of 3GPP2 UMB was monitored with limited effort, since none of the NGMN Members was considerably involved in any UMB trials.

 

LTE/SAE Trial Initiative (LSTI)

The LTE/SAE Trial Initiative was an open initiative driven by vendors and operators founded in May 2007 and successfully concluded its work in January 2011. LSTI joined the leading operators and the key LTE/SAE. For more information visit www.lstiforum.org

 

The main objectives of LSTI were:

 

  • Demonstrate 3GPP LTE/SAE capabilities
  • Stimulate development of LTE/SAE ecosystem
  • Promote industrialization of LTE/SAE
  • Promote LTE/SAE as NGMN technology
  • Consider NGMN and 3GPP requirements as input for LSTI tests

 

LSTI established different work streams to reflect the different stages in the technology development process. The Proof of Concept phase verified the basic LTE/SAE functionality and performance using pre-standard proprietary equipment. LSTI co-ordinated industry-wide interoperability testing of standards compliant equipment from different vendor pairs, stimulating early feedback into the standard. In 2009 LSTI demonstrated LTE capabilities and advantages in near-commercial conditions. Friendly users tested mobile broadband applications, using pre-commercial form factor terminals in several field trials. In January 2011, LSTI concluded its work and presented the outcomes at the Mobile World Congress 2011 (the presentation is available at
Presentation Package of Joint GSMA-NGMN Conference Stream - MWC).


Main Deliverables

Main deliverables of the NGMN Trial project:

 

  • Field Trial Requirements document (2 releases in 2008),
    Describes test requirements to enable the verification of the NGMN White Paper requirements through field trials, including
    - Trial setup recommendations
    - End-to-end proof point descriptions
    - Reporting recommendations;
  • Concept for NGMN-approved trials;
  • Evaluation reports on proof-of-concept, technical field trials, and friendly customer trials.

Achievements

In the initial phase of the NGMN Trial activities, a collaboration framework was established defining the informal interface towards LSTI and towards the WiMAX trial activity, as well as legal and confidentiality aspects. Furthermore, the NGMN Field Trial Requirements were finalised.
