GTP信令规定了移动台MS接入GPRS网络的隧道控制和管理协议要求，信令主要执行建立、修改和删除隧道的功能。在用户面，GTP利用GSN之间建立的隧道传送用户数据分组。-GTP signaling provides GPRS mobile station MS network access control and management of the tunnel requirements in the agreement, signaling the main executive to establish, modify and delete functions of the tunnel. In the user plane, GTP using GSN tunnel established between the transmission of user data packet.

扩频通信.第一本有关扩频系统的专著是R.C.Dixon于1976年出版，是一本IEEE专利，1977年出版。1978年在日本京都召开国际无线通信咨询委员会公布研究成果。1982年在美国召开第一次军事通信会议，两次报告在军事中的应用。1985年美国提出CDMA(码分多址)的概念同年美国联邦通信委员会(FCC)制定扩频通信的标准和规范，逐步转入民用的商业化研究-Spread Spectrum Communication. The first book on spread-spectrum systems is RCDixon monograph published in 1976, is an IEEE patent, published in 1977. In 1978 in Kyoto, Japan, an international wireless communications Advisory Committee published research results. 1982 in the United States held its first military communications conference, two reports in the military applications. The United States in 1985 proposed CDMA (Code Division Multiple Access) the concept of the same year the United States Federal Communications Commission (FCC) the development of spread spectrum communication standards and norms, and gradually transferred to the commercialization of civilian research

如何计算结构体的大小运算符sizeof可以计算出给定类型的大小，对于32位系统来说，sizeof(char) = 1 sizeof(int) = 4。基本数据类型的大小很好计算，我们来看一下如何计算构造数据类型的大小。 -How to calculate the structure of the size of the sizeof operator can calculate the size of a given type, for a 32-bit systems that, sizeof (char) = 1 sizeof (int) = 4. Basic data types of the size of the fine calculation, we take a look at how to calculate the structure data type size.
