摘要
不同类型无线网络的融合是宽带无线通信发展的必然趋势。在异构融合网络环境中,无论何种无线网络都能够提供无所不在的最优服务。具有挑战性的问题就是异构多模终端的管理系统和接入选择功能架构的设计。一种异构多模终端管理架构通过与各协议层的有效交互,可以适应多种接入标准与技术的要求,实现多模异构终端的无缝接入和移动。接入选择是核心研究问题之一,接入选择功能架构主要包含3个模块:接入适配、移动管理、用户偏好。
The convergence of heterogeneous wireless networks is an inevitable trend in broadband wireless communications development. In heterogeneous convergence environment, to secure the best Quality of Service （QoS） at anywhere provided by any wireless network of any kind, the most challenging task lies in the design of management system for heterogeneous multi -mode terminals and access selection functional architecture. A type of management architecture for heterogeneous multi-terminal via effective interaction with all protocol layers is adaptable for multi-access standards and technical requirements to facilitate enable seamless access and mobility for multi-mode heterogeneous terminals. As the core subject for research, access selection functional architecture mainly consists of three modules, namely as access adaptation, mobility management, and subscriber preference.
