Huawei releases SDN-based mobile backhaul solution
Mar 08, 2013 (Datamonitor via COMTEX) --
Huawei Technologies Co., Ltd., an information and communications technology solutions provider, has released the LTEHaul, a SDN-based mobile backhaul solution that provides support for the planning, construction, maintenance, and optimization of mobile backhaul networks.
By adopting the software defined networking (SDN) technology, the solution 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.
By addressing the large bandwidth and seamless quality service requirements of new LTE/LTE-A-oriented technologies such as eMBMS, COMP, and eICIC, the Huawei LTEHaul solution provides users with site-free and virtual service access. Meanwhile, the fronthaul, backhaul, and core are unified in the network structure, thereby overcoming the bottleneck of traditional GSM/UMTS network structure and bandwidth.
By leveraging the SDN technology, the network service bearing and control are separated, and far-end massive cell site gateways (CSGs) and small cell site gateways (SCSGs) can be managed on aggregation site gateways (ASGs). This significantly simplifies network management and O&M, saves the operating expense (OPEX) by approximately 60%, and facilitates fast service provisioning.
"As LTE networks are put into large scale commercial use, future mobile backhaul networks must be able to carry more new services and support more application scenarios. This will bring tremendous challenges to the live mobile backhaul networks.
"Huawei's LTEHaul solution will not only help operators resolve these challenges but also address the present GSM/UMTS bearing demands, allowing mobile backhaul networks to leap over the large gaps and smoothly evolve to LTE/LTE-A networks," said Wei Feng, vice president of the Huawei fixed network business unit.
