| 摘 要： | 应急流动测震台网和遥测地震台网的性质不同，因此在组建方式上也具有差异性。VPN是一种新的网络技术，它能够提供远程访问，外部网和内部网的连接，价格比专线或者帧中继网络要低得多。目前，VPN技术在专用的传输业务中得到了广泛的应用。本文简要介绍了VPN技术原理，以及通过运用该技术借助GPRS和CDMA传输网络来实现流动测震信号的远程传输。

| Abstract: | The nature of mobile seismic network and telemetered seismic network is different, so we must construct they with different method. VPN is a new network technology. It can provide remote access, and the connection of internal network and external network. Compared with dedicated line or frame relay network, its price is very cheap. At present, VPN is widely applied in dedicated transmission. In this paper, VPN principle and how to transform mobile seismic signal through CDMA/GPRS VPDN with this technology is introduced. |
