Huawei introduced an SDN-based mobile backhaul solution that simplifies the operation and maintenance (O&M) and management of mobile backhaul networks and shortens the time to market (TTM) of new services. The solution helps operators resolve network issues during the evolution to LTE networks.
First, a large gap exists between massive LTE hotspots and limited hotspot backhaul sites. The LTEHaul solution extends the traditional backhaul network downwards to form a fronthaul, facilitating the management and maintenance of massive hotspot backhaul nodes.
A second large gap is present between the vast increase in the LTE bandwidth and the limited bandwidth on the traditional backhaul network.
Third, there is a large gap between the traditional backhaul and core networks. The LTEHaul solution stretches the traditional backhaul network upwards to achieve end-to-end fast service provisioning, protection switching, and fault locating from eNodeBs to evolved packet cores (EPCs).
