面向特殊领域的IMS网络架构模型研究

Study on Special Domain-oriented IMS Network Architecture Model

依托公众移动网络的无线接入体系,研究构建面向特殊领域应用的IP多媒体子系统(IMSP Multimedia Subsystem)网络架构,将对特殊领域用户的管理控制集中到内部IMS进行,可以满足特殊单位或部门对通信的特殊要求,实现对内部业务的自管自控,同时保证内部通信的安全保密。在对现有IMS架构进行了分析的基础上,提出面向特殊领域的IMS网络架构模型,并以注册流程和特殊用户之间的语音呼叫流程为例,研究探讨了系统的会话流程。

Based on the public mobile network access framework, is built up, and the management over users in the special domain is centralized into the internal IMS, the IMS network architecture in special domain this could satisfy the special communication demands of corresponding departments and ensure the control of internal business and the security of internal communications. Based on analysis of the current IMS architecture, a new IMS system model for the special domain is proposed. And finally with registration and voice calling process as an example, the system session process is explored.
