LTE networks offer great benefits for mobile operators and their subscribers. For one, they are designed to easily and efficiently meet consumers’ growing demand for mobile data, which will be a crucial factor in ensuring an optimum customer experience. Plus, LTE simplifies the backhaul network, removes the need for complex and expensive network control functions, and reduces CAPEX and OPEX by using cheaper transport technology like IP and Ethernet.
However, despite these benefits, we’ve also seen a number of operational impacts arise for mobile operators deploying LTE. What many mobile operators don’t realize is that they need to dramatically change their Operations Support Systems (OSS) to plan, launch, optimize and manage these LTE networks. Here are a few tips to get the most out of LTE deployments:
Invest in mobile network planning
With higher frequencies of small cells and femtocells, a greater rate of change within the mobile network and higher expectations from subscribers, mobile operators will need to focus on their mobile network planning efforts. This particularly applies to backhaul planning, which will need to be very closely linked to the radio planning process in order to coordinate cell capacity with backhaul capability. Mobile operators will also benefit from tying in network performance data to this process in order to ensure they are able to continuously optimize LTE networks and ensure optimal performance.
Extend fault performance tools to the access network
As mobile operators scale their LTE access networks, they will need enhanced fault and performance tools to support the growing volume of connected devices. This will be accelerated as mobile operators are relied upon to manage quality of service (QoS) for more and more applications and services, such as VoLTE. With this shift, there will also be a need for trend and predictive functions that can pre-warn mobile operators of issues that require troubleshooting.
Maximize service value while supporting cost reduction
In addition to making these OSS changes, mobile operators must improve other internal processes so that they can not only deliver a great customer experience to subscribers but also realize the business benefits of LTE. This includes aligning network planning, network performance management and network optimization in order to optimize LTE functionality.
Be sure to join me at LTE World Summit for my presentation on this topic on June 25th at 2:40 p.m. During this talk, I will dive further into potential LTE stumbling blocks, and explain how the combination of LTE networks and targeted OSS changes can improve subscriber QoS and benefit mobile operators’ businesses.
