NGMN Open OAM-IRP Ensembles Recommendations

10. January 2014//in Publications //by datenfluss

From their Release 99 onwards, 3GPP / SA5 adopted a new methodology to specify OA&M interfaces between Element Management System (EMS) and Network Element System (NMS). In their Management Reference Architecture, this interface is known as the Itf-N Interface.

There is a need to define « Ensembles » / « Profiles » / « Packages », i.e. some grouping of IRPs to determine which IRPs are needed in a given network management application profile. It is obvious that the subset of IRPs needed for Bulk Configuration Management of an LTE network will be different from the subset of IRPs needed for Fault Management of an EPC network.

The objective of this document is to present the IRP Ensemble concept, i.e. what it is and why it is important for MNOs but also for Telecom Equipment Manufacturers and 3rd-party tool vendors.

NGMN Identifies Key Performance Indicators (KPIs) and Target Values for Assessing Green Networks22. February 2023 - 10:11
Frankfurt, Germany, February 22nd, 2023. The Next Generation Mobile Networks Alliance (NGMN) today published ‘Green Future Networks: KPIs and Target Values for Green Network Assessment’ addressing the key issue of how operators measure, report, track, and act on their environmental and energy footprints, while maintaining high service quality for end users.

Measuring progress towards environmental goals is a critical success factor for operators as they move forward on their journeys towards greater environmental sustainability and energy efficiency in their networks and operations.

“NGMN’s vision is to provide impactful guidance to the industry with Green Future Networks being a core strategic priority”, said Anita Doehler, CEO, NGMN. “With the publication of KPIs and Target Values for assessing Green Networks, we are realising that vision by supporting and enabling operators and their wider ecosystem partners to measure and manage their progress towards their sustainability goals”, she added.
NGMN guides the industry with 6G Requirements and Design Considerations14. February 2023 - 11:26
Frankfurt, Germany, February 14th, 2023. In its latest 6G publication, “6G Requirements and Design Considerations”, the NGMN Alliance (NGMN) has defined several important requirements for 6G. By providing this guidance to the industry, NGMN takes on a leading role in avoiding fragmentation of future 6G standards and achieving affordable deployments and services valued by end users.

The publication offers guidance and input to Standards Development Organisations (SDOs) working towards realisation of the vision of communication systems for 2030 and beyond, currently being developed by ITU-R. It has been developed on the understanding that there will be an evolution towards 6G without distinction between any new 6G technology, an evolution of 5G or a combination of both.

New approaches have been identified within this publication covering digital inclusion, energy efficiency, environmental sustainability, and flexible deployment. Potential new capabilities related to prospective use cases are discussed qualitatively as well as new paradigms to address traffic growth, capacity needs, minimise complexity and provide alternatives to densification.
