CDMA系统的仿真程序，在此基础上研究了下CDMA系统等。

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.
