Huawei, a leading global information and communications technology (ICT) solutions provider, has unveiled its Backhaul Adaptive Solution, a mobile broadband (MBB) solution that provides operators with an IP Backhaul Performance Monitor (IPPM) and IP Backhaul Quality Management (IP SQM) services for improved IP backhaul efficiency.

The widespread global adoption of smart phones has ushered in a new era of mobile internet access, leading to unprecedented increases in data traffic. Data from Huawei's top 40 operator networks shows that end user data traffic in 2011 increased seven fold compared to 2007. Service experience demands also continue to grow on a yearly basis, resulting in significant operator investment in infrastructure. In response to this, Huawei has developed the Backhaul Adaptive Solution, which not only improves network performance, but also IP backhaul efficiency.

The Backhaul Adaptive Solution's IPPM service constantly monitors QoS between the eNodeB and the EPC Serving Gateway according to speed, delay, jitter and packet loss. The solution adjusts for bandwidth bottlenecking according to changes in network quality and realizes adaptive adjustments for bandwidth transmission. The IP SQM service focuses on the downlink from the EPC Serving Gateway to the eNodeB to realize smooth levels of data traffic and buffering. The IP SQM also supports both static and dynamic bandwidth adjustments based on data provided by the IPPM and increases backhaul usage and improves user experience by decreasing packet loss and retransmission.

Xu Weizhong, President of Huawei Packet Core Network, said, "Thanks to the support we have received from the world's top operators, Huawei is proud to see the success of the Backhaul Adaptive Solution in the global telecommunications market. We firmly believe that in the MBB era, Huawei's LTE and EPC user-oriented end-to-end solutions will maximize profits for operators."

The Backhaul Adaptive Solution has been successfully tested by top global operators. Test results show that when S1 link congestion occurs, TCP transmission efficiency is improved by up to 50% when the solution is employed.
