Facing the explosive growth of mobile data traffic and user demand, mobile network operators are investing significant amount of time, effort and money in building new and upgrading existing infrastructure. As the new generations of networks are getting more and more complex while network load rockets high, planning, configuration, management, optimization, operation and healing of a cellular network all become increasingly challenging. At present, an operator typically first identifies specifications, studies the geographic area to be covered and population, and performs simulation and analysis using radio frequency (RF) planning tools based on statistical and measured propagation models. After cells are deployed, extensive drive tests then follow to fine tune the network. The operator monitors live network performance by sending specifically designed signals to user equipment (UE) and examining the UE response. However, today's network operators do not have mechanisms to directly obtain a UE side's quality of experience (QoE) and quality of service (QoS) information. This Engage project utilizes a comprehensive set of QoE/QoS key performance indicators of a subscriber's device, innovatively developed by Tutela Technologies Ltd., to aid in network planning and optimization. The project aims to i) study how the user experience KPI can be employed in cellular network optimization and planning; ii) optimize the way KPIs are measured for the purpose of network optimization and planning. In the longer term, the project lays the foundation to the development and application of UE KPIs for self-organization networks (SON). The successful outcome will provide Tutela with concrete ideas to convince operators adopting their KPIs, which is critical to the expansion of Tutela's markets. Moreover, the mobile operators and users will benefit from the improved network performance, and reduced radio planning complexity, capital expenditure and energy consumption of the cellular network.
