Abstract

A detecting base station transmits user zone information to wireless communication device when the presence of a wireless communication device is detected. A detecting base station receives a detection signal, such as an uplink signal, transmitted from the wireless communication device to determine the presence of the wireless communication device. The detecting base station notifies the core network the detection by transmitting a device proximity message and, after receiving authorization from the network, transmits the user zone information within the broadcast channel used by the originating base station communicating to the wireless communication device.
