Paper Abstract

With the rapid development of Urban Rail Transit, the demand and service quality of communication system for the subway is higher and higher. Good communication system is an important factor to ensure the safe operation of Urban Rail Transit. Telephone Communication is the basic hand of train command in Urban Rail Transit, including public telephone and private telephone. At present, SPC Exchange Technology is adopted in public telephone and private telephone system in Urban Rail Transit while domestic essential equipment suppliers such as ZTE, Huawei and other companies, declared phasing out the production of SPC Exchange Equipment. Thus, a new idea would be put forward to solve this problem. Soft-switch Technology can support various forms of information. It is a new network technology which integrates voice, data, image and fax services. Soft-switch technology as a representative of scientific and technological innovation can be effectively integrated with Urban Rail Transit Communication System. And the quality of communication service can also be improved. Taking Wuhan Metro as an example, this paper discusses Soft-switch technology and its application in urban rail transit communication system. After successful pilot, it can be extended to other cities.
