【摘要】：为了适应运营商对列车乘客信息系统越来越高的性能要求,提出了基于会话发起协议(SIP)的乘客信息系统设计的基本原则,并阐述其在列车语音通信中的应用方案.该方案充分利用SIP方法和会话描述协议谈判机制完成了会话的管理和媒体的协商.为验证方案的可行性,完成了语音控制单元的软件结构设计,并实现了各软件模块.系统测试表明,该列车语音控制单元能够准确地完成所设计的广播对讲功能.
[Abstract]:In order to meet the requirements of the operators for the higher and higher performance of the train passenger information system, the basic principles of the passenger information system design based on the session initiation protocol (SIP) are put forward, and the application scheme of the system in the train voice communication is described. The scheme makes full use of the SIP method and the session description protocol negotiation mechanism to complete the session management and media negotiation. In order to verify the feasibility of the scheme, the software structure of the speech control unit is designed, and each software module is implemented. The system test shows that the train voice control unit can accurately complete the designed broadcast intercom function.
