摘　　要：在常规模拟无线通信系统中,大部分系统控制采用的是模拟信令,受信令编码容量及时间所限,只能为终端提供简单的功能。这里介绍了一种编解码简单易行可靠、编码容量大的数字信令,使常规模拟无线通信系统具有较强的系统功能及控制灵活性。不但能和用户的某些事件及控制之间通信,还通过信号传输协议给系统增加数字数据处理性能,增强了其基本的语音通信功能。Analog signaling is used in most controlling system of the conventional wireless communication systems. But as a result limited by coding capacity and time, these systems can only provide some simple functions for End-Users. Here we introduce a sort of Numeric signal- ing with big capacity which can not only make encode ＆ decode simple and reliable but also more perfect function and flexible control can be acquired in conventional wireless communication system. Therefore, not only the system can communicated with some event and control, but also the signal transport protocol enhances the basic voice correspond function by add numerical data processing capability to the system.
