Performance Monitoring with Predictive QoS Analysis of LTE Backhaul

LTE (Long Term Evolution) represents an emerging technology that will change how mobility service providers connect user devices to their infrastructure over IP networks. To support growing mobile broadband data loads, an all-IP Ethernet cell site backhaul (CSBH) network infrastructure will make possible real-time high bandwidth applications using mobiles. This paper discusses the changes that LTE will bring and examines network operations impacts on the CSBH. It also introduces operations support system solutions to address performance management (PM) to determine if impaired LTE service has occurred. This paper covers major aspects of system solutions, including: capabilities for auto-detection, root-cause analysis based on correlation algorithms, and traffic congestion control mechanisms. It also presents functionality for quality of service (QoS) trending projections to manage traffic capacity and trigger the traffic control mechanisms, to protect network resources and improve the overall customer experience.
