Claim:
1. A method comprising: receiving, at a target transceiver node, an uplink signal transmitted from a wireless communication device receiving wireless service from an originating transceiver node, the uplink signal transmitted within originating uplink time periods assigned to the originating transceiver node for receiving uplink signals and non-overlapping with target uplink signal time periods assigned to the target transceiver node for receiving uplink signals from target served wireless communication devices when providing wireless service to the target served wireless communication devices; sending a message identifying the wireless communication device, the target transceiver node having a target node geographical service area at least partially overlapping with an originating node geographical service area of the originating transceiver node; and at least estimating a proximity of the wireless communication device to the target transceiver node based on the uplink signal, wherein sending the message comprises sending the message when the proximity is below a threshold.
