1.
This paper analyses the architecture and function of Iu interface,and proposes a design scheme of Iu interface in MSC(CS),which can integrate QoS of service and the resource of software-hardware in system significantly.
在第三代移动通信系统中,如何实现移动业务交换中心(MSC)和无线网络控制器(RNC)之间的Iu接口是一个复杂的问题。
2.
Iu interface,as the interface between wireless access network and Core Network in the third-generation(3G) mobile communications system,provides data transmission on both the control plane and the user plane,interconnecting the wireless access network and core network.
Iu接口是第三代移动通信系统中无线接入网与核心网之间的接口,用于完成控制面和用户面的数据传输,实现无线接入网与核心网的互连互通。
3.
MSC is divided into MSC Server and MG(Media Gateway),and Iu interface becomes the universal interface between UTRAN and CN.
为了满足用户对网络性能不断增长的需求,3GPP在R4核心网中引入软交换技术,将移动交换中心(MSC)分成移动交换中心服务器(MSC Server)和媒体网关(MG),并选择Iu接口作为无线接入网(UTRAN)和核心网(CN)的通用接口。
5) IU Normal
IU标准
6) IU&NU
IU比NU比
补充资料：iu
[ao],[ou],[iu]都是复韵母。前一个元音开口度大，发音长而响；后一个元音开口度小，发音短而轻，比较模糊。从前一个元音到后一个元音是自然滑行，不能跳跃。
