1)  inter-MSC handover
跨MSC切换
2)  The MSC to which the MS is handed over in a basic Handover MSC-B
被切换到的MSC
3)  The Controlling MSC on which the call was originally established
发起切换的主控MSC
4)  The MSC to which the MS is handed over in a subsequent
被切换到的第三方MSC(后续切换)
5)  virtual cut-through switching
虚跨步切换
1.
Focusing on the particular characteristics of virtual cut-through switching network, the authors find that message dependencies are localized between adjacent queues.
利用虚跨步切换技术中消息的依存关系只与相邻缓冲区队列相关的特点,设计了一种称为维度气泡流控(DBFC)的新型流控策略。
6)  Mobile Switching Center MSC
移动交换中心MSC

!ANSYS命令流
! 写单元及节点数据文件
! 作者:陆新征,清华大学土木系
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
!选中所有单元
ALLSEL,ALL
! 得到当前模型中的总节点数
*GET,NNode,NODE,,COUNT, , , ,
!输出节点
*CFOPEN,Node,txt
*VWRITE
('coordinates')
*VWRITE,chrval(3),chrval(NNode),chrval(0),chrval(1)
(4A5)
