A detecting base station detects a wireless communication device by intercepting an uplink communication signal intended for an originating base station. In response to the detection of the wireless communication device, the detecting base station sends a message to the core network. The detecting base station includes a mobile communication device detector configured to intercept the uplink communication signal transmitted from the wireless communication device to the originating base station of a communication network. A network interface within the detecting base station is configured to send a device proximity message to the communication network where the device proximity message is based on the proximity of the wireless communication device to the detecting base station. The device proximity message may be a handoff request, distance, or other information that is derived or otherwise related to the intercepted uplink communication signal.
