CDMAEV-DV试验网主要测试EV-DV系统对数据业务支持及其和CDMA20001x网络的前向兼容性问题,并充分考虑今后网络升级的各种可能性,为今后的建设做好准备、积累经验。本文主要研究EV-DV试验网的核心网络的建设方案,提供了两种方案建设核心网电路域:第一,混合网方案,在现有的CDMA网络上利用软件升级达到EV-DVReleaseC规范要求;第二,独立网方案,新建MSC/VLR和HLR,这种方法较少影响原有网络。对于核心网分组域本文主要研究简单IP情况下的网元设置和IP地址分配方案。
CDMAEV-DV trial network mainly tests EV-DV system’s data service support and its forward compatibility with CDMA20001x network, fully considers the various possibilities of network upgrade in the future, prepares for future construction and accumulates experience. This paper mainly studies the construction plan of the core network of EV-DV trial network and provides two schemes to construct the core network circuit domain: first, the hybrid network solution, which achieves the EV-DVReleaseC specification through software upgrade on the existing CDMA network; Second, the independent network program, the new MSC / VLR and HLR, this method less affected the original network. For the core network packet domain This article focuses on the case of simple IP network settings and IP address allocation program.
