GSM-RSIM卡具有铁路通信自身的特点,其中存储了一系列支持GSM-R特殊应用要求的基本文件。这些基本文件中包含GSM-R编号方案的各种信息。研究利用GSM-RSIM卡中这些信息在铁路通信中实现用户拨号帮助的方法,避免GSM-R用户记忆铁路通信中各类复杂的号码结构,并给出具体的实现流程和举例。
The GSM-RSIM card has the characteristics of railway communication itself, storing a series of basic files supporting the special GSM-R applications. These basic documents contain a variety of information about the GSM-R numbering plan. This paper studies how to use the information of GSM-RSIM card to help users dial in railway communication, and avoids all kinds of complex numbers structure in GSM-R users memorizing railroad communication. The specific implementation flow and examples are given.
