Abstract:
A method for hand-off of a CDMA access mobile from a macrocell to a femtocell is disclosed. The method includes tracking each femtocell which mobile stations have allowed access incorporating a mobile station identification for each of the mobile stations. The method continues with storing the mobile station identification for each femtocell. This may occur in a database or similar structure. The message continues on with requesting a hand-off from the macrocell to the femtocell via PN offset and the method concludes with querying all femtocells that have that PN offset that are within range of the macrocell's neighbor list. If only one femtocell fits that criteria the method is done. If more than one femtocell fits that criteria, a priority list may be set up based at least in part on the number of times and/or frequency that the mobile station has been allowed access on the femtocell. The method could include allocating resources for all high priority femtocells and cleaning up resources for the femtocells that do not send a hand-off complete message.
