GSM-R is the new wireless communication standard for railway networks. It has been developed under European Union sponsorship to assist railways in achieving their goals of network interoperability, reduced operational costs, improved safety at higher speeds, and delivery of new services for the benefit of passengers and employees.

GSM-R Applications

GSM-R services standardized within ETSI are collectively called the Advanced Speech Call Items (ASCI). ASCI comprises of the following three services:

• eMLPP (enhanced Multi-Level Precedence and Preemption) allows resource preemption for priority/ emergency calls
• VBS (Voice Broadcast Services) allows groups of users to receive common information
• VGCS (Voice Group Call Service) allows groups of users to make calls within/among the groups

Examples for Railway features are:

• Functional Addressing and presentation of the functional numbers
• Location Dependent Addressing
• Access Matrix
• Emergency Calls
