GERAN is the radio part of GSM / base station controllers ( A interfaces, etc . ) The network represents the core of a GSM network, through which phone calls and packet data are routed from and to the PSTN and Internet to and from subscriber handsets.

The transponders digitally convey their identification information and other relevant bits of information via wires to a trackside Base Station Controller ( BCM ), which uses a data radio to communicate with the locomotive s on-board computers, allowing the locomotives to know precisely when they have reached a particular waypoint.

A Cell Broadcast Centre ( CBC ), a node which is a source of SMS-CB, is connected to a base station controller ( BSC ) in GSM networks or to a radio network controller ( RNC ) in UMTS networks via standardized interface over TCP / IP . The BSC-CBC interface is described in 3GPP standard TS 48.049; however, non-standard implementations exist.
