| Abstract: | As an advanced CDMA network technology, CDMA VPDN has solved many problems occurred in early CDMA network applications. In order to achieve a good understanding of its application mechanism, this article began with an introduction of CDMA 2001 1x network techniques and structures. Then taking Sichuan digital seismic observation networks as an example, we particularly illustrated the structure form and fashion of CDMA VPDN IP digital seismic observation networks. Lastly, common problems and their solutions in CDMA VPDN IP networks were discussed. |
