Abstract
A method and system for resolving handover in the presence of coverage area identifier conflict is disclosed. In a market area in which an LTE RAN and CDMA RAN operate, a base station receives a PCI that indicates a particular one of the LTE coverage areas detected by a mobile terminal. The base station determines that at least two of the LTE coverage areas have the particular PCI. Thereafter, the base station determines which one of the LTE coverage areas is the particular LTE coverage area that was indicated by the particular PCI based at least in part on a particular PN offset that indicates a particular CDMA coverage area of the CDMA RAN. The base station then arranges for handover to the particular LTE coverage area.
