METHOD TO ALLOW HAND-OFF OF A CDMA MOBILE FROM IMS FEMTOCELL TO CIRCUIT MSC

摘要

A method for hand-off of a cell division multi-access mobile from an internet protocol base network to a circuit mobile switching center is disclosed. The system includes determining whether a hand-off is appropriate based at least in part on signal strength of a call for a mobile unit. The method continues with sending a message indicating that the mobile identification of the mobile unit and a target cell locating the circuit identification of a circuit that is available to support a hand-off. The method continues on with allocating the circuit and reconfiguring the mobile unit to a macrocell (CDMA access network) and legacy MSC via the circuit.
