Abstract
A system and method is provided for determining the availability of a mobile communications device on a network based on a prediction that the device will cross a pre-defined service boundary between two different coverage areas serviced by two different service providers. Specifically, when the device is predicted to cross the service boundary, or has crossed the boundary, a notification of a change in service is issued to at least one of the user of the device, a presence service, or another network operator. The notification may include a change in the presence status of the mobile communications device.
