LTE backhauling deployment scenarios

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.

Since the migration phase might pose concerns to operators still engaged in 2G/3G deployment or in maximizing the profitability of their existing networks, the scenarios described hereafter have been designed considering, among the other aspects, possible paths to migrate from circuit based network, and represent a kind of target architecture to aim at. Clearly, the path to an all packet-based backhaul will depend on the specific market, technical environment and services an operator is operating or dealing with.

Although this paper primarily focuses on LTE backhauling, some advanced topics are also referenced and constitute the basis for further studies on LTE-A.

The goal of this paper is to describe how the mobile backhauling network will evolve to support the deployment of LTE. Read the whitepaper for further insights:
