NGMN notes future mobile broadband spectrum shortage and supports Agenda Item 8.2 at ITU-R WRC-12 towards spectrum studies and possible additional allocations to the mobile service and identification of bands for IMT at ITU-R WRC-15. NGMN urges that ITU-R Working Party 5D have the lead role in conducting the relevant studies.
The document describes how a model is developed to predict traffic levels in transport networks used to backhaul LTE eNodeBs. Backhaul traffic is made up of a number of different components of which user plane data is the largest, comprising around 80-90% of overall traffic, slightly less when IPsec encryption is added. These results reveal that the cell throughput characteristics for data carrying networks are quite different to those of voice carrying networks.
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.
