摘要
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。
CDMA EV-DV trial network is main to test EV-DV system on sustaining the data traffic and to test some problems about it＇s compatibility with CDMA 2000 1x network. It is considered that this network can be scalable. Constructing the test network accumulates experiences to prepare the future 3G network. This paper provides some projects to construct the Core Net of the EV-DV test network. There are two means to construct the Circuit Network of Core Net, The first is the mix network. This means can evolve the existing network to suffice the requirement of the EV-DV Release C standard. The second is independent network. By this means it is required to build new MSC/VLR and HLR, but it hardly infects the old one. About the Packet Network, this paper is main to research the net nodes setting in the position of Simple IP and also provides a project to assign IP addresses.
