Iub接口是3G中NodeB与RNC之间的接口,Iub接口的传输组网方式主要有基于ATM的传输组网和基于IP的传输组网,Iub接口基于IP的传输组网方式有:基于IPoverE1/T1overSDH的IP组网、基于PDH/SDH的IP组网、基于数据网络的IP组网、基于MSTP的IP组网、基于分路传输的IP组网。介绍了IUb接口基于IP的协议栈结构、功能、传输组网方法及人机命令配置方法。
The Iub interface is an interface between the NodeB and the RNC in the 3G network. The transmission networking modes of the Iub interface mainly include an ATM-based transmission network and an IP-based transmission networking. The IP-based transmission networking mode of the Iub interface includes: IPoverE1 / T1overSDH IP networking, PDH / SDH-based IP networking, data networking-based IP networking, MSTP-based IP networking, shunting based IP networking. This paper introduces the architecture, function, transmission networking method and man-machine command configuration method of IP-based protocol stack of IUb interface.
