Abstract
A system is described herein that includes mobile communication devices and a cellular base station to communicate with a telecommunication network. The mobile communication devices access telephony service through the cellular base station when inside a geofence. The mobile communication devices determine whether they are inside the geofence based on distances from proximity beacons. When outside of the geofence, the mobile communication devices are prevented from accessing telephony service through the cellular base station. When inside the geofence, the mobile communication devices may access telephony service through the cellular base station. The mobile communication devices may only make and receive calls from mobile communication devices of a specific other system. When a call is received at the system, the mobile communication devices of the system are rung. To enable this, a serving call session control function of the telecommunication network forks a call directed to the system.
