Unified Communications System Research and Application Based on Cloud Computing About Intelligent Policing Collaboration

摘要:

针对统一通信的资金高投入,为了提高统一通信的普及性,提出了托管型统一通信方案；整体方案基于云计算架构,由业务层、呼叫控制层、终端接入层和业务与网络管理层组成,同时分析了统一通信业务,包括基本语音业务、多媒体会议、协同类业务、统一消息、终端业务等；研究了统一通信语音网关,设计中继网关提高组网能力,设计接入网关扩展终端业务；探索了云架构的实现技术,包括P2PSIP技术、虚拟化技术、视频编解码技术等；P2P架构能够使系统动态适应节点失效的情况,提高整个系统的可靠性与鲁棒性；针对线路可提供带宽的不确定性及不稳定性,为保证视频质量,视频会议采用可伸缩视频编码技术；研究成果应用于公安智能警务协同系统,提高了语音系统的用户感知；同时分析了行业现状,展望了未来前景。

Abstract:

For high investment funds to unified communications, in order to improve the popularity of unified communications, UCaaS solution was designed and developed. The overall scheme was based on the cloud computing architecture and consisted of the service layer, the call control layer, the terminal access layer and the service and network management layer. Simultaneously unified communications services were analyzed, including basic voice services, multimedia conferencing, collaborative services, unified messaging, terminal services, etc. Voice gateway techniques were studied. the trunk gateway was designed to improve the networking capability, the access gateway was designed to expand the terminal business. The implementation technology about cloud architecture was explored, including P2PSIP technology, virtualization technology, video codec technology.P2P architecture can make the system adapt to the situation of node failure dynamically and improve the reliability and robustness of the whole system. In order to ensure video quality, video conferencing use scalable video coding technology to deal with the uncertainty and instability of the line bandwidth. The research results were applied to the public security intelligent police cooperation system, which improves the user perception of the speech system. Industry status was analyzed. At the same time, we look to the future prospects.
