联通武广高铁RNC Iur接口流量分析及互联接口的设计

A Case Study of RNC Iur Interface Traffic Analysis and Interface Design

武广高铁(湖南段)WCDMA网是专网的覆盖方式,每个本地网设计一个高铁专用的网络控制器(RNC),在UTRAN内部,不同RNC之间通过Iur接口互联。本文通过Iur接口流量的分析,对Iur接口的互联进行了设计,从而保证了跨RNC的软切换顺利进行,防止列车高速运行状态下发生硬切换造成掉话。

A dedicated network is used for the WCDMA network coverage in the Hunan section of the Wuhan-Guangzhouhigh-speed railway. Each lo- cal network has a special RNC, andevery RNC is connected by fur interface. The article tries to de- sign IUR＇S interconnection through analyzing the flow of RNC＇s IUR to prevent hard handover.
