USSD在GSM-R智能网中的应用与研究

Study and application on USSD of GSM-R IN

智能网是在原有通信网的基础上设置的一层叠加网络。GSM-R是一种专门应用于铁路的综合数字移动通信系统。GSM-R作为UIC支持开发的欧洲铁路无线专用通信系统,具有适应铁路运输特点的优势,其标准、技术和产品在铁路上的应用得到许多欧洲国家的验证,达到了商用的程度。铁道部也决定采用GSM-R作为我国铁路综合移动通信的技术体制。主要描述了利用USSD的方式实现GSM-R智能网中功能号的注册、注销与管理及被叫用户位置的获取,并给出了详细的解决方案。

IN is an overlay network on the original core network. GSM-R is an integrated digital communication network used specially in railway system. As the European railway＇s wireless communication system supported by UIC, the GSM-R system has many advantages in the aspect of railway transportation. The standard and product of the GSM-R system have been applied in many European countries. The railway department has taken the GSM-R system as the special railway communication system of our country. The function number＇s register, logout, management and getting the called subscriber＇s location information in the GSM-R wireless intelligent network which is implemented by USSD way are briefly described. Then the specific resolve solution is introduced.
