摘要:

目前,专用移动通信网(简称专网)大多采用集群通信系统,主要功能局限在语音和低速数据,网络覆盖范围有限,各专网之间也难以实现漫游和互通。如何利用一个共用的技术平台实现不同专网之间、专网与公网之间的融合,并且支持宽带互联网应用例如高分辨率图像、视频和大数据量传输,是目前各国政府和相关行业、产业面临的重要课题。LTE 是公认的未来移动宽带发展的主流技术,具有高吞吐量、低延时、无线频谱适应性强等优势。本文提出泛在共享移动宽带网(ubiquitous shared mobile broadband network)的概念,介绍了其设计的基本思想、全新的网络架构、严格的安全管理机制、提供的业务和优势,最后提出了泛在共享移动宽带网的发展策略。

Abstract:

Today's public safety networks are designed mostly for trunk radio and originated from original 2G equivalent type of digital radio technology.These networks provide mainly voice communication and limited data communication in limited coverage.In addition,today' public safety networks are not interoperable and do not support inter-agency collaborations.Now the law enforcement forces and governmental agencies face the challenge of multi-organization collaboration and multi-unit common platform which accomplishes the interoperability and roaming among commercial networks and public safety networks of different agencies,more importantly,capable of supporting Internet based applications,such as images,video,and large data transfer.LTE,with its advantages of high throughput,low latency and bandwidth flexibility,is emerging as the unquestionable champion of future mobile broadband technology.By leveraging the technology advantage of LTE standard and its flat IP architecture,this paper proposes a new concept in building public safety networks and meeting the challenges:ubiquitous shared mobile broadband network(USMBN).Its conceptual overview,network architecture,security,novel services and benefits are introduced.The strategies to develop USMBN are also proposed and discussed in this paper.

Key words: private mobile communication network, LTE, evolved packet core, security, ubiquitous shared mobile broadband network
