1. In a radio communication system having a plurality of transceivers, the transceivers having known locations, and at least one remote unit communicating a signal to a candidate transceiver, a method for selecting a serving transceiver for the remote unit comprising:

  • a.) estimating the at least one remote unit'"'"'s location within the radio communication system in response to collected signal characteristics measured by a set of transceivers from the plurality of transceivers wherein estimating the at least one remote unit'"'"'s location further comprises;

    (i) segregating those transceivers in the set of transceivers with respect to the candidate transceiver, into distance ranges, wherein transceivers segregated in any single range are a substantially similar distance from the candidate transceiver;

    (ii) determining for each transceiver a per-transceiver likelihood contribution that the at least one remote unit is in the region of the transceiver in response to at least one of;

    a distance range to which the transceiver was segregated, a number of transceivers within the distance range, a collected signal characteristic of the remote unit, and a predetermined RF propagation model associated with the distance ranges;

    (iii) repeating steps (i-ii) above for any transceiver in the set; and

    (iv) summing the per-transceiver likelihood contributions for each receiving transceiver to compute a metric for each transceiver;

    b.) selecting the serving transceiver as a transceiver of the set of transceivers having the highest metric.
