基于UMA技术的话音业务互切换技术的研究

摘要

在我国，中国移动已成为全球为数不多的几个同时拥有固定网络与移动网络的大运营商之一，如何充分利用固定网络资源与移动网络资源成为了全球通信业界研究的热点之一。本平台的目标是利用UMA技术有效的将Wi-Fi网络与TD-SCDMA网络和GSM网络结合在一起，实现三网融合，将话音业务和数据业务进行分流；由一个具有自主开发产权的UMA控制器(UNC)和双模手机构成。在不影响现有移动网络的基础上，通过增加UMA控制器，双模手机能够通过Wi-Fi网络无缝接入移动通信网络，实现WLAN、TD-SCDMA网络和GSM网络相互切换、漫游、无线上网等功能，移动用户不需改变号码即可享受该功能。%In our country, China Mobile has become the world as one of the major operators of the few also has the fixed network and mobile network, how to make full use of cyber source fixed and mobile cyber source has become one of hot research of global communication industry. This platform is the effective use of UMA technology in Wi-Fi network and TD-SCDMA network and GSM network together, realize the integration of three networks, phonetic and data business flow. UMA controller by an independent development of property (UNC) and dual mode mobile phone. Does not affect the existing mobile network, by increasing the UMA controller, dual-mode mobile phone can use Wi-Fi network to realize seamless access to mobile communication network, WLAN, switch, TD-SCDMA network and GSM network roaming, wireless internet access and other functions, without changing the number of mobile users can enjoy the function.
