Patent ID: 10805788

Abstract:
A system and method that enables the setting up of an incoming call from an originating endpoint of a calling party to a mobile station of a called party who is registered as a roamer in a visited cellular network. In response to receiving a dialed number, or other call information, the system determines whether to set up the call to the mobile station of the called party through a pre determined, over-the-top (OTT) call service that bypasses the visited network. The OTT call service is offerable as a feature to the called party by the party's home mobile network operator (MNO). Call handling for the OTT call service is provided through i) an OTT feature server that is coordinating the incoming call, an application server that is affiliated with the OTT feature server, and iii) a OTT software application that is executing on the called party's mobile station.
