基于GSM-R的传统的录音系统具有通信事件和部分通话无法记录的局限，并且需要GSM-R网络的特别支持。文中提出了一种基于GSM-R信令监测的选择录音系统( OVRS)，通过信令监测技术，对呼叫信令流程进行分析，根据录音规则选择性地记录语音和与语音通话相关的事件，有效解决了以上问题，具有易规划、易管理、安全保密、易操作、易维护的特点。首先介绍了OVRS系统的硬件架构和软件系统设计；然后，阐述了系统包含的信令链路自动识别、选择录音、DXC设备控制等关键技术；最后，描述了系统的实现方案和实验结果，并对该系统的应用前景和社会效益、未来的工作进行了展望。

Traditional voice recording system based on GSM-R has limitations that communication events and part of calls can’ t be recor-ded,and the need for special support of the GSM-R network. In this paper,the Optional Voice Recording System ( OVRS) based on the GSM-R signaling monitoring is proposed,with signaling monitoring technologies to analyze the process of calling signaling,recording voice alternatively according to recording rules and tracking communication events relating to voice call,which effectively solves the a-bove problem. The OVRS is easy to plan,manage,secure,operate and maintain. First,the hardware architecture and software system de-signing of OVRS are introduced. Second,the key technologies of OVRS are elaborated,which includes the automatic identification of the signaling link,optional recording and DXC equipment control. Finally,the system implementation and experimental results are described, and the system application prospects,social benefits and future work are explained.
