【摘要】：移动互联网蓬勃发展,各种移动应用爆发式增长。目前移动办公应用的使用也随着4G网络的兴起而越来越普遍。在此趋势下,传统办公应用将过渡到在线办公应用,在线办公应用将发展到云办公应用。云办公与移动应用相结合将成为未来的主流工作模式。在此背景下,研究协作办公类应用对LTE网络的无线侧传输,所带来的流量、带宽、时延等的影响尤为重要。本文研究了移动协作办公类应用的两种实现方案(云桌面实现方案和Web实现方案)对LTE网络无线侧时延、流量和带宽的影响,并进行了对比分析。此研究将有助于移动网络运营商更好地了解移动协作办公类应用在LTE网络中的表现和对于网络资源的需求,从而可以更加有针对性的制定网络建设和优化方案。首先,本文介绍了协作移动办公应用的两种技术实现方案,并调研了主流的协作办公应用业务,确定了该类应用以Office在线办公、电子邮件、在线存储三大业务为主。其次,分别针对三大业务的两种实现方式,选取典型软件应用,在客户端抓取数据包,分析数据包大小和时延特征。然后,针对业务的数据特征,建立业务的数学模型。根据建立的模型,在LTE仿真系统中实现各个业务的核心逻辑。最后,通过对仿真结果的评估,对比两种技术实现方案在LTE网络环境中的性能。
[Abstract]:Mobile Internet is booming, various mobile applications explosive growth. At present, the use of mobile office applications is becoming more and more common with the rise of 4G networks. Under this trend, the traditional office application will transition to the online office application, and the online office application will develop to the cloud office application. The combination of cloud office and mobile application will become the mainstream work mode in the future. In this context, it is particularly important to study the effects of collaborative office applications on the wireless side transmission of LTE networks, such as traffic, bandwidth, delay and so on. In this paper, the effects of two implementation schemes of mobile collaborative office applications (cloud desktop implementation and Web implementation) on wireless delay, traffic and bandwidth of LTE network are studied and compared. This study will help mobile network operators to better understand the performance of mobile collaborative office applications in LTE networks and the need for network resources, so that more targeted network construction and optimization can be made. First of all, this paper introduces two kinds of technology realization schemes of collaborative mobile office application, and investigates the mainstream collaborative office application business, and determines that this kind of application mainly consists of Office online office, email and online storage. Secondly, aiming at the two kinds of implementation methods of the three major services, the typical software applications are selected to grab the data packets at the client side and analyze the data packet size and delay characteristics. Then, according to the data characteristics of the business, the mathematical model of the business is established. According to the established model, the core logic of each service is realized in the LTE simulation system. Finally, by evaluating the simulation results, the performance of the two schemes in LTE network is compared.
