面向固定移动融合环境的P2PSIP系统设计

全业务运营是电信市场继语音和宽带接入服务之后的下一个增长点,而基于IP的融合有线网络和无线网络的语音服务则是全业务的重点之一。本文通过分析现有VoIP网络存在的问题以及固定移动融合网络环境下VoIP的特点,提出一种新型双层重叠网架构的P2PSIP架构,并阐述了新型架构的优点及双层重叠网之间的通信机制。新型架构能有效提高系统的安全性、健壮性和用户节点资源利用效率,更好的满足固定移动融合网络环境下VoIP对带宽、网络质量和安全性的要求。

Design of the Fixed Mobile Convergence Oriented P2PSIP System

Full services operating is the telecommunication market＇s next growth point after voice service and broadband access services, while the voice service which based on the IP network combining the fixed and mobile network is the killer application. In this paper, we analyzed the disadvantages of the existing VoIP network and highlighted the characters of the mobile VoIP systems in the Fixed Mobile Convergence （FMC） environment. Based on them, we proposed a new two-layer-overlay P2P SIP architecture and elaborated the merits and communication mechanism of the architecture. The architecture can effectively improve system＇s security, robustness and user resources utilization efficiency, which better fulfill the requirements of bandwidth, network quality and security for VoIP in FMC environment.
