This strategy introduces the concept of sub rating channel to CPCB ( Compact pattern based channel borrowing ), and significantly reduces the forced termination probability at the expenses of temporarily degrading the voice of quality of partial calls. 这种策略将半速率信道的思想引入到新近提出的CPCB策略中,以短时间降低部分呼叫的话音质量为代价,来降低系统的呼叫阻塞。
On this basis, the paper discuses four principles of pharmaceutical marketing channel designation : multilayer channels principle, choice marketing principle, double-wins principle, and termination improvement principle. 在此基础上论述了药品分销通路设计的四个原则:多层通路原则、选择分销原则、双赢原则、终端优化原则。
