System and method for wireless call handover from a shared network to a home network
First Claim
1. A method for selecting a cell for handover of a continuing communication, wherein the communication is initially routed through a first cell of a partner mobile network, comprising:
- establishing a flag for use by a partner mobile network and a home mobile network, the flag indicating that a mobile station belongs to a subscriber to the home mobile network;
storing information including the flag in a database that is in communication with the partner mobile network;
setting a flag with respect to a communication involving the mobile station that is being carried on a partner mobile network as including a mobile station of a subscriber of a home mobile network;
determining that a handover from a first cell in the partner mobile network to a second cell among a plurality of candidate cells, is necessary to maintain communications for the mobile station; and
initiating a handover of the communication from the first cell to the second cell if the second cell belongs to the home mobile network, wherein whether the second cell belongs to the home mobile network is determined, at least in part, by evaluating whether the flag is set.

Abstract
A method and system for differential handover of a call into a home mobile network from a partner mobile network is disclosed. An exemplary embodiment of a method for differential call handover includes setting a flag in the partner mobile network which identifies a mobile station, whose communication is being handled by the partner network, as a subscriber to the home network. In an exemplary embodiment, channel information associated with possible handover cells of the home network is retrieved by the partner network after the latter receives a communication from the mobile station indicating a handover condition.

12. A method for increasing revenues of a home mobile communications network, comprising:
-
establishing a flag for use by a partner mobile network and a home mobile network, the flag indicating that a mobile station belongs to a subscriber to the home mobile network; storing information including the flag in a database that is in communication with the partner mobile network; setting the flag when the partner mobile network handles a communication to a mobile station belonging to a subscriber to the home mobile network; and handing over the communication back to the home mobile network whenever the mobile station enters a region in which the home network operates, the handover being effected due to the flag being set, whereby revenues are increased to the home mobile network by handling the communication through the home mobile network whenever the mobile station is in a region in which the home mobile network operates.
