摘要
随着软交换技术的不断发展和日渐成熟,其在业务功能和组网方式方面具有更大的优势,因此建立基于软交换技术的公务电话系统成为轨道交通通信系统中的热点。本文对软交换技术的概念、特点及其在轨道交通公务电话系统的方案进行了分析,论述了软交换完全能够满足轨道交通公务电话系统的需要。
With the continuous development and gradual maturity,the soft-switching technology enjoys more advantages in terms of services and networking modes.Thus,to build soft-switching technology based administrative telephone switching system has become a heat topic for the rail traffic communication system.This article makes an analysis on the conception and characteristic of soft-switching technology as well as its solution for administrative telephone system of rail traffic communications,and demonstrates that soft——switching technology can fully satisfy the requirements of administrative telephone switching system for rail traffic communications.
