TD-SCDMA和WiMAX技术融合实现宽带无线移动通信系统

TD-SCDMA and WiMAX Technology Convergence of Broadband Wireless Mobile Communication Systems

本文主要论述了基于TD-SCDMA和WiMAX技术融合实现一种新型的宽带无线移动通信系统。在该系统中,TD-SCDMA接入网提供广域无线覆盖,支持高移动性,提供话音业务和中、低速数据业务;WiMAX接入网提供热点区域覆盖,支持游牧移动性,提供高带宽流媒体数据服务,两种接入技术在网络层实现汇聚,通过网络层移动性管理技术,共享核心网络和业务系统,实现两种接入网的统一的无线资源管理以及统一的用户管理和计费,移动终端可以在该系统下的两种网络之间实现无缝漫游和切换。该种新型的移动通信系统能够很好的满足用户对移动通信业务的使用要求,也能够有力支持TD-SCDMA大规模独立组网,增强TD-SCDMA的竞争力;同时,也为TD-SCDMA系统的演进和跨越式发展提出新的思路。

This paper discusses the TD-SCDMA and WiMAX-based technology convergence to achieve a new type of broadband wireless mobile communication system.In this system,TD-SCDMA access network to provide wide-area wireless coverage,support high-mobility,providing voice services and in the low-speed data services;WiMAX access network to provide hotspot coverage,support nomadic mobility,provide high-bandwidth streaming media data Services,two kinds of access technologies to achieve convergence at the network layer,through the network layer mobility management techniques,shared core network and business systems to achieve the unity of two kinds of wireless access network resource management and unified subscriber management and billing.
