【摘要】：為了適應運營商對列車乘客信息系統(tǒng)越來越高的性能要求,提出了基于會話發(fā)起協(xié)議(SIP)的乘客信息系統(tǒng)設計的基本原則,并闡述其在列車語音通信中的應用方案.該方案充分利用SIP方法和會話描述協(xié)議談判機制完成了會話的管理和媒體的協(xié)商.為驗證方案的可行性,完成了語音控制單元的軟件結構設計,并實現(xiàn)了各軟件模塊.系統(tǒng)測試表明,該列車語音控制單元能夠準確地完成所設計的廣播對講功能.
[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.
