一体化网络中支持寻呼的移动性管理机制

摘要

一体化网络是一种基于身份信息和位置信息分离的网络体系结构,能够有效支持主机的移动性.但随着用户数量的增多,信令开销可能成为制约网络发展的瓶颈之一.为了有效地减少移动过程中的信令开销,本文在一体化网络体系结构的基础上,提出了一种支持寻呼的移动性管理机制.此外,本文还建立了解析模型,导出了信令开销的计算公式,并分析了不同系统参数对信令花费的影响.性能分析结果表明,寻呼机制能够减少信令开销,从而增强了网络的性能.%Universal network is one of identifier/locator separation network architectures, which can efficiently support host mobility. However, as the number of mobile devices increases, the signalling overhead may become the bottleneck of the network. To address this issue, this paper proposes a new mobility management mechanism to support paging in the universal network. To evaluate the proposed scheme, we develop an analytic model to formulate the signalling cost and analyse the influence of the different factors on the signalling cost. The analytical results show that the proposed paging scheme could decrease the total signalling cost and improve the network performance.
