Abstract

A global prepaid roaming services method and apparatus is described in which a roaming phone located in a first region places an outgoing call to a destination party in a second region, and responsive to placing the call, a service processing node (SPN) establishes a first call connection between the roaming phone and the SPN, a second call connection between the SPN and the destination party is established and the SPN bridges the first and second call connections to establish a call connection between the roaming phone and the destination party. Incoming calls originating in a first region made to a wireless phone roaming in a second region are established by signaling from the first region to a home region associated with the wireless phone in order to determine that the wireless phone is roaming in the second region; signaling a cellular-switching center (CSC) in the second region, responsive to the determination that the wireless phone is roaming in the second region, to inform the CSC in the second region of a call connection request to the wireless phone; routing the call, responsive to the call connection request, from the CSC in the second region to a service processing node (SPN) in the second region and establishing a first call connection from the originating first region to the SPN in the second region; launching a message from the SPN in the second region to the wireless phone, the message instructing the wireless phone to establish a second call connection with the SPN in the second region; and bridging the first call connection with the second call connection, responsive to establishing the second call connection with the SPN.
