现有IMS网络引入NFV方案研究

Research on the Introduction of NFV Solution to the Existing IMS Core Network

在竞争激烈的移动互联网时代,以VoLTE为核心的融合通信将不可避免地成为运营商加速转型、应对互联网公司跨界竞争的重要业务形态。现有IMS网络升级改造为VoLTE业务控制核心网过程中,考虑适时引入NFV技术,积极主动应对网络向ICT融合的云架构转型,成为当前运营商发展的主题。结合NFV标准和产业发展情况,分析在现有IMS网络引入NFV的策略,探索IMS网络NFV的演进路线。

In the highly competitive mobile Internet era, converge communication with VoLTE as the core, inevitably become the impor- tant service form which is used by operators to accelerate the transformation, and to deal with cross-border competition in In- ternet company. During the upgrade from the existing IMS core network to VoLTE service control core network, the theme of the current operator development should be the introduction of NFV technology in good time, actively respond to the transfor- mation that IMS network architecture becomes cloud architecture of ICT integration. Based on the standards and industrial de- velopment of NFV, it analyzes the strategy of introducing NFV in existing IMS network, and explores the NFV evolution route of IMS core network.
