摘要
对ＦＴＡＭ传输协议和交换机内部产生实时呼叫记录的机制进行研究，介绍了一种利用ＯＳＩ协议栈， ＦＴＡＭ ＡＰＩ编辑接口实现联机话务数据的实时采集系统．针对移动交换机两种常用的话务数据传输接口（８０２ｘ与Ｘ．２５）。对其ＯＳＩ协议栈中底层协议的各自特点进行了对比分析．
In telecom service management systems, the online real-time billing is the base of most real-time service disposals. Further more the real-time CDRs gathering plays an impel-taut role in real-time billing. This paper researches into the mechanism of FTAM protocol and CDR stream in switch, and it introduces the implementing of real-time CDRs gathering by OSI protocol stacks and FTAM API. Because most switches have the interface of 802.x or X.25, this paper also compares the 802.3 with the X.25.
