摘要
基于某种大型局用程控交换机座席控制系统的实际工作原理,详细分析了座席控制系统呼叫过程中的各种定时问题,研究了具体解决方法,即:定义一个含有定时器字段的双向链表,并按定时先后排序.对不同的定时数据,维护不同链头.定时处理定时器,同时根据链头呼叫记录的状态和定时器值进行不同处理.该方法不仅适用于交换机的座席控制系统,对其他多任务复杂系统也适用.
On the basis of the practical working principle of the operator's station control system(OSCS) of the large-size SPC exchange for a telephone office, various timing problems in OSCS during call are analyzed, and the method to make the timer work validly and reliably is studied. A doublylinked list with timer field is defined, and it is sequenced according to timing order. According to thecall record state and the timer message, the head is processed respectively together with the regularprocessing of the time.
