    核心网统一平台是融合的基础,对于不同的系统来说,物理单板是共用的,通过加载不同的软件来实现不同系统中的功能。
    基于统一硬件平台,实现了全业务融合。
  • 最下边的导风槽是4面进风,进风量大,导风效果好。
  • ZXUR 9000 UMTS可以通过增加单板和加载软件的方式,转化为ZXUR 9000 GU产品形态。接口板和交换板占用后插槽位,管理单板和处理单板占用前插槽位。
  • 控制框:背板采用BCTC(Backplane of Control Center),主要负责RNC控制面的处理(RCB)。第1个控制框中还包括了操作维护(ROMB)、时钟(CLKG)和控制面的交换单元(THUB)。多个控制框之间、控制框和资源框之间,通过THUB交换数据。
    资源框:背板采用BGSN(Backplane of General Switch Network),负责用户面处理(RUB)和接口的接入(如:E1、STM-1、信道化STM-1、GE/FE等)。2个资源框以上必须使用交换框,以完成资源框之间的数据交换。
    交换框:背板采用BPSN(Backplane of Universal Switch Network),提供系统的一级IP交换平台,作为系统用户面的交换单元。超过2个资源框时必须使用交换框进行框间用户面数据的交换。
  • EGFS含GPS卡,默认配置带GPS。
  • ESDTG的处理能力比ESDTT大,多了2个子卡,因为处理Abis和Ater的处理量大于处理A口的,所以Abis和Ater配ESDTG,当A口需配置语音增强功能,用ESDTG,否则用ESDTT。
    EGPB建议不同接口分开配置,其他单板可以不同接口混用。
  • CMP是1+1的,DMP和RUP是资源池方式,是负荷分担的,但这里的负荷分担是由上层调度的,单板本身对负荷分担没做什么工作。
  • 对于IPA和IPAbis而言,控制面都是承载于SCTP协议,在CMP处理。
    即IPA方向上由平台管理偶联;而Abis方向上由GSM应用动态建立偶联。
    TDM A MTP2在接口板处理,MTP3/SCCP在CMP处理
  • CS媒体面数据流承载于RTP协议,在Abis口与A口之间经过GUP的转发进行直通,其中A口的RTP/RTCP协议到GUP单板终结;PS数据在GUP单板进行处理(相当于iBSC的UPPB),RTP的相关处理由GUP完成。UDP发到Gb口。
    RTP数据流在接口板进行UDPMux和RTPMux复用。其中,Abis口方向上固定使用RTP压缩头格式,而A口方向上要根据RTCP协商的结果决定压缩与否。
    CS语音将在IPA口和IPAbis口对接,因此CS数据将取消按载频打包的处理模式;而同时PS数据出于每载频数据时间对齐的考虑,依然采用载频打包的发送机制。
  • RTP在ETCB的DSP上终结。ETCB到接口板为内部UDP报文
    PS同全IP流程
  • UMP功能板通过软件版本加载实现2种逻辑板
    OMM逻辑板
    OMM、Log、MR/CDT功能,等同于V3的SBCX单板,支持1+1备份
    外部接口
    1×GE:到EMS以太网端口
    2×GE: Fabric平面,连接2个交换板,与OMP、EGPB通信
    OMP逻辑板
    系统全局处理,含OMCB转发
    支持与CMP共物理CPU
    外部接口
    2×GE:Base平面,连接2个交换板
    2×GE:Fabric平面,连接2个交 换板,与OMM通信
  • 130Mbps 是RUB单板PS能力建议商用值,单板最大PS能力为450Mbps,基于签约HS1024业务。
  • ZXUR 9000 UMTS容量大、集成度高,扩容方便,可有效节省机房面积,适应各种业务环境和业务量的快速增长,保护运营商的投资。
  • ZXUR 9000 UMTS支持ATM/IP双协议栈,可支持E1、STM-1、信道化STM-1接口、FE、GE等各种物理接口,在不同阶段,可根据不同的情况实现灵活组网。
  • 1.高集成度,节省投资
    ZXUR 9000 UMTS容量大、集成度高,扩容方便,可有效节省机房面积,适应各种业务环境和业务量的快速增长,保护运营商的投资。
    2.全IP设计,适应网络演进需求
    ZXUR 9000 UMTS内部采用基于IP的交换平台,使得数据传送高效灵活。相对于ATM架构的平台,IP交换管理维护方便、配置简单,扩容灵活、传送效率更高,传送机制也更为灵活,故更能适应未来移动数据业务高速增长的需求。
    3.可靠性高
    ZXUR 9000 UMTS具有非常高的可靠性,整个系统完全采用冗余设计,无单点故障,系统支持在线的软件下载,可远程加载远程启动。
    4.丰富的接口,组网灵活
    ZXUR 9000 UMTS支持ATM/IP双协议栈,可支持E1、STM-1、信道化STM-1接口、FE、GE等各种物理接口,在不同阶段,可根据不同的情况实现灵活组网。
    5.配置简单,维护方便
    ZXUR 9000 UMTS单板种类少,仅包含处理板,接口板和交换板,使得配置简单,扩容方便,并可减少备件种类,降低维护成本。
