从号码图表谈数字语音用户收号问题

用户拨号是语音业务的重要环节,接入网完成用户收号,并配合交换设备实现语音呼叫功能。通过对用户拨号实现方式的梳理,并比较其在传统电路交换网络以及数字语音网络中的区别。报告了数字语音网络中3种不同的收号方式及其之间的关系,并对按号码图表收号进行了重点研究,通过典型交互信令分析了影响按号码图表收号效率的匹配模式、定时器等重要因素。依据上述因素报告了如何构造号码图表,并结合工程应用实例进行了探讨总结。

The discussion about digital voice user number receiving problems from the digitmap

The user dialing is a very important link in voice service,the access network fulfils user number receiving and cooperates with LE (Local Exchange) to realize the voice call function. Through combing user dialing methods, we compare the difference in traditional circuit-switched network and digital voice network. The application of three different user number receiving modes and the relationship among them in the digital voice network have been reported.We focus on the user number reception according to the digitmap. Through the typical interactive signal,we analyse the important factors affecting the digitmap efficiency which includes matching mode, timer and so on. On the basis of the above factors, we report how to construct the digitmap, and has carried on the discussion and summary combined with engineering application.
