Claim:
1. A method of tracking area management in a femtocell network at a mobility management entity, the method comprising: receiving, from a plurality of femtocell base stations, physical cell identities (PCI) of neighbor macrocell base stations of each one of the femtocell base stations as macrocell tracking area information associated with each one of the femtocell base stations; generating an integrated tracking area list by extracting, based on the PCIs of neighbor macrocell base stations, at least one tracking area identity of a macrocell tracking area overlapping a femtocell tracking area of respective femtocell base station, and adding the extracted at least one tracking area identity of the overlapped macrocell tracking area into a tracking area list associated with the respective femtocell base station; storing and managing the generated integrated tracking area information; and controlling femtocell base stations and macrocell base station, which are only included in the integrated tracking area list, to transmit a paging message to associated user equipments for finding user equipments in an idle mode.
