1. A method for resolving identification code ambiguities in a wireless access network, the method comprising: accessing an identification code associated with a cell in the wireless access network that is detected by a mobile device; determining a probability score for candidate cells that are assigned the identification code in the wireless access network, the probability score based on a likelihood that a candidate cell is a cell in the wireless access network associated with the identification code detected by the mobile device; and selecting one of the candidate cells as an origination cell of the identification code detected by the mobile device based on the determined probability scores, wherein determining a probability score for candidate cells that are assigned identification code in the wireless access network includes: calculating a number of intra-frequency neighbors shared between a predetermined source cell and the candidate cell; calculating a number of scrambling codes shared between the predetermined source cell and the candidate cell; determining whether the predetermined source cell is on a neighbor list of the candidate cell; determining whether the predetermined source cell is on a detected set report of the candidate cell; and calculating an inverse of a distance or geoscore between the predetermined source cell and the candidate cell.
