根据对无线ATM (AsynchronousTransferMode)通信网中越区切换问题的研究 ,提出了一种新的基于虚通道(VP)的快速越区切换方案。文中详细描述了系统在采用CDMA (码分多址 )接入方式情况下这种方案的软切换过程 ,并与虚拟连接树方案就有线资源利用率等方面进行了比较。
According to the research of handoff problem in wireless ATM (AsynchronousTransferMode) communication network, a new fast handoff scheme based on virtual channel (VP) is proposed. The paper describes in detail the soft handoff process of this scheme when the system adopts CDMA (code division multiple access) access mode and compares it with the virtual connection tree scheme on the utilization of wired resources.
