The NGMN Alliance addresses top requirements for global success of mobile broadband

(PresseBox) ( London, UK/Frankfurt, Germany, )
In an Executive Press Briefing today at Mobile World Congress, Barcelona, the NGMN Alliance outlined the top technological requirements for successful deployment and operation of mobile broadband on a global scale.

These include:
- Global roaming: In a world of scarce spectrum and a variety of mobile access technologies, multi-band and multi-mode devices are a prerequisite. In its current work programme the NGMN addresses the key requirements.
- Convergence of network management: The large variety of technologies - even within a single operator's network - demand for an efficient management of fixed/mobile networks. This is a challenge for all major mobile network operators.

NGMN Board Directors gave their insight and opinion on these challenges and shared solutions developed by the NGMN partners. Further updates and conclusions will be made public during the NGMN Industry Conference and Exhibition on June 13-15 in San Francisco, US, see

Global Roaming
Yuhong Huang, Deputy General Manager China Mobile Research Institute, on behalf of NGMN MBMM project, focused her presentation on the industry requirements with regards to global roaming and expressed the need for a single, cost effective global UE platform. In addition she explained the requirement for multi-band multi-mode devices and discussed the feasibility, as well as the technology roadmap for the next two to three years.

One major challenge Mrs Huang named is the scarcity of spectrum that leads to various LTE bands in different regions. Development of devices that are able to support these frequency bands and in addition multiple technologies is a prerequisite for global roaming, but it is a challenge to implement more than 10 LTE bands in current products.

The NGMN Alliance has launched the project "Multi-band multi-mode" together with all major international chipset and device manufactures to enable knowledge transfer across players and to work on a roadmap towards multi-band multi-mode devices. It is the goal of this project to reduce complexity through an effective UE platform. This will be a prerequisite for improved end-user experience and mandatory to allow for global LTE roaming.

Mrs Huang stated that: "The NGMN Alliance invites all device ecosystem vendors to join the MBMM activity to enable cost effective multi-band multi-mode global UE platform and ecosystem, significantly enhancing the economy of scale and seamless LTE global roaming".

Management of Converged Fixed and Mobile Networks
Klaus-Jürgen Krath, SVP Radio Networks, Deutsche Telekom AG, highlighted in his contribution, today's operator challenges of having to manage a variety of network and service production infrastructures, from mobile and fixed network environments up to converged networks and services across regions. This has an enormous impact on network operations, which NGMN targets with its project on "Next Generation Converged Operations Requirements" (NGCOR).

The objective of this NGMN project is to reduce complexity and integration costs in the area of network management by achieving standardised interfaces between the Telco infrastructure and the OSS (Operations Support Systems). NGCOR aims to obtain more flexibility and reduced time-to-market in the introduction of services through standardised network management functionalities for converged fixed and mobile networks.

"The detailed operations requirements, developed by the NGMN Alliance, have already been shared and reviewed with all leading Telco and IT vendors and involved industry organisations", said Klaus-Jürgen Krath. "The NGMN operators encourage all these industry stakeholders to support in a joint effort the further enhancement of the requirements and, in particular, the implementation of NGCOR results in order to achieve the targeted benefits and savings. The deployment will be driven by operators putting the requirements in upcoming tenders."
