摘要
文中对认知网络的概念、背景和研究现状进行了深入调研,在此基础上,基于核心网融合采用的IP多媒体子系统体系架构,通过对认知网络进行研究,提出具有认知特性的新型网络的网络架构,在分层的网络架构中引入了关键实体以及认知过程,并设计了认知过程的行为模型,保证整个通信过程涉及的所有实体都具有自感知、自配置、自适应能力。并进一步针对访问控制展开研究,结合传统异构融合网络的接入选择技术,引入认知过程,实现新型认知网络体系架构中的访问控制方法。
This paper discusses first the concept, background and current research status of cognitive network, and based on this, proposes the key technologies of cognitive network, gives IMS architecture, suggests the network architecture for novel heterogeneous network with cognitive characteristics, describes the key entity and cognitive process in hierarchical network. Meanwhile, the behavior model of cognitive process is designed, ensuring that all entities involved in the communication procedure could be self-aware, self-configurable and self-adaptive. This paper treats of the cognitive access control issues in cognitive heterogeneous network. And by integrating traditional network selection method and introducing cognitive process, the access control method in new cognitive network architecture is realized.
