随着通信技术的不断进步,民航空管传统话音交换系统使用的TDM技术存在系统接口数量受限制、只提供话音服务难以融合新业务新应用、系统互联困难等问题,已经逐渐无法满足业务需求。基于网络的Vo IP(Voice Over Internet Protocol)话音技术的出现与不断发展,很好地解决了这些问题,并随着电信等运营商传输骨干线路的网络化,Vo IP话音技术将逐步取代传统的TDM技术,成为民航空管地空通信主流的话音通信技术。
With the continuous improvement of communication technology, the number of system interfaces used in the traditional voice switching system of civil aviation ATC is limited. Only the provision of voice services is difficult to integrate with the new applications of new services, and the interconnection of system is difficult. Therefore, the TDM technology has been gradually unable to meet the business needs. With the advent and continuous development of Voice over Internet Protocol (VoIP) voice over Internet, Vo IP technology will gradually replace the traditional Voice over Internet Protocol (VoIP) voice technology, which has solved these problems. With the network transmission of backbone lines such as telecom operators, TDM technology, air traffic control to become the mainstream of civil aviation ATC voice communications technology.
