摘要
使任何用户在任何时间任何地点都能获得具有服务质量(QoS)保证的服务,同时提高网络的覆盖范围和通信容量,是异构网络融合必须考虑并解决的关键问题。异构环境下具有QoS保证的关键技术研究以及通信容量分析是异构网络融合的重要研究内容。异构网络融合中具有QoS保证的关键技术研究主要在呼叫接入控制(CAC)算法、垂直切换算法、异构资源分配算法和网络选择算法等无线资源管理算法方面。在异构网络融合系统中使用新颖的多跳网络结构可以扩大网络的覆盖范围,降低传输功率,增加系统通信容量和吞吐量。
To provide any subscriber from anywhere at anytime with services that have both secured Quality of Service (QoS) and simultaneous expansion of network coverage and communications capacity is a key problem that has to be considered and solved in heterogeneous networks convergence. Key technologies for a secured QoS and communications capacity analysis under heterogeneous environment are important subjects for research. Key technologies for a secured QoS are mainly on radio resource management algorithms covering Call Admission Control (CAC) algorithm, vertical handoff algorithm, heterogeneous resource allocation algorithm, network selection algorithm, etc. The applications of a novel multi-hop in heterogeneous convergence system serve the purposes of network coverage expansion, transmission power reduction, system communication capacity and throughput increase.
