3G移动数据业务中HTTP和FTP业务建模研究与实现
摘要
随着第三代移动通信系统的不断发展,移动数据业务在3G网络业务中所占的比例不断增加,为了更好的进行网络规划和网络性能的分析,需要对网络中数据业务模型进行研究,从而了解各种数据业务的特性,准确的分析3G系统的性能。
与第二代移动通信系统相比,3G系统对数据业务的承载能力有了很大的提高。从目前数据业务的使用情况上来看,数据业务还是以接入互联网为主,HTTP业务在所有互联网业务中占据主导地位,因此对于HTTP业务模型的研究在数据业务模型研究中是重中之重。
本文基于现有业务模型的研究成果,对于HTTP(?)口FTP协议的特点及业务特性进行了分析,分别提出了HTTP和FTP业务的业务模型,同时结合现网采集的移动数据业务的数据,通过一系列的建模流程,建立面向不同场景、不同维度的HTTP和FTP业务模型,并且计算相对应的业务模型指标参数,实现了移动数据业务建模系统的开发,对于实际网络中移动数据业务的发展规划,系统的配置规划和数据业务的预测等应用具有重要的价值。
With the development of the third generation mobile communication system, the proportion of mobile data services in 3G network business is increasing. In order to better plan the network and analyze the network performance, we need to study the data service model. From that we can learn the characteristics of all kinds of data services and analyze the performance of 3G system accurately.
Compared with the second generation mobile communication system. 3G system has improved a lot in carrying capacity of data services. According to the data services available, most of the bussiness based on the internet. And HTTP service plays a significant role in internet bussiness, so the study of HTTP service is the top priority.
This paper proposes HTTP and FTP service model based on the characteristics of these protocols and the existing research results. In the fourth part, we design a series of modeling process to establish these models for different scenes and dimensions and develop a prototype of mobile data service modeling system. This system can be used to predict and plan the mobile data services in the network, has important reference value.
