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.

面对移动的数据流量和用户需求的爆炸式增长，移动的网络运营商正在投资 在建设新的和升级现有基础设施方面需要大量的时间、精力和资金。为 新一代的网络变得越来越复杂，而网络负载却越来越高，规划， 蜂窝网络的配置、管理、优化、操作和恢复都变得越来越重要 挑战性目前，运营商通常首先识别规范，研究要被配置的地理区域， 覆盖和人口，并使用基于无线电频率（RF）规划工具进行模拟和分析 统计和测量传播模型。部署单元后，进行广泛的路测， 微调网络。运营商通过发送专门设计的 向用户设备（UE）发送信号并检查UE响应。然而，今天的网络运营商不 具有直接获得UE侧的体验质量（QoE）和服务质量（QoS）的机制 信息. 该Engage项目利用用户的一组全面的QoE/QoS关键性能指标， 由Tutela Technologies Ltd.创新开发的设备，以帮助网络规划和优化。的 项目旨在i）研究如何在蜂窝网络优化中使用用户体验KPI， 规划; ii）优化KPI的测量方式，以实现网络优化和规划的目的。在 从长远来看，该项目为UE KPI的开发和应用奠定了基础， 自组织网络（SON）。成功的结果将为Tutela提供具体的想法， 说服运营商采用他们的KPI，这对Tutela的市场扩张至关重要。而且 移动的运营商和用户将受益于网络性能的改善和无线电规划的减少 蜂窝网络的复杂性、资本支出和能量消耗。
