摘要
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。主要讨论了在TD-SCDMA网络建设中Iu接口用户面的假活现象对网络性能的影响,并提出了具体的解决措施,包括增加MSC Server对Iu用户面资源的监测功能,利用SNMP协议在MSC Server中检测并向无线网元管理器(WEM)实时反馈Iu接口用户面状态。最后将该方案以系统补丁的形式,在上海贝尔阿尔卡特实验室TD-SCDMA试验网中进行功能验证与测试。
In order to support the require of performance in the network, softswiteh is introduced into R4 by 3GPP. MSC is divided into MSC Server and MG （Media Gateway）, and Iu interface becomes the universal interface between UTRAN and CN. In this article, softswitch Iu interface user plane AAL2 pseudo -effect in TD -SCDMA network is researched, and a new procedure is designed for testing Iu interface user plane quality in MSC Server： and reporting it to WEM in time. At last, performance simulation made in ShangHai Actel Lab is introduced.
