Claim One:
1. A method for locating a mobile radio terminal in a radio communications network, the method comprising: identifying a set of cells about an approximated location of the mobile radio terminal; identifying at least one cell in the identified set that is unreported by the mobile radio terminal, the remaining cells in the identified set being reported; determining a maximum number of cells that can be reported by checking a network threshold; if the reported cells in the identified set exceed the maximum number of cells, compare interference levels from the reported cells against a level of signal strength of the weakest reported cell and determine a first probability that an unreported cell is weaker than the weakest of the reported cells; if the reported cells in the identified set do not exceed the maximum number of cells, compute a maximum interference level from the reported cells in the identified set and determine whether the maximum interference level is greater than a receiver sensitivity threshold of the mobile radio terminal; if the maximum interference level is greater than the sensitivity threshold, compute a second probability of the unreported cell being weaker than the maximum interference level; if the maximum interference level is not greater than the sensitivity threshold, compute a third probability that the unreported cell is weaker than the mobile radio terminal sensitivity threshold; and determining a location of the mobile radio terminal on the basis of at least of the first probability, the second probability and the third probability.
