PREDICTING USER AVAILABILITY FROM AGGREGATED SIGNAL STRENGTH DATA
First Claim
1. A method for determining the availability of a user of a mobile communications device on a network, comprising the steps of:
- providing service coverage data comprising at least a segment of a predefined service boundary;
determining, using tracking data for the mobile communications device, when the mobile communications device is likely to cross the segment of the predefined service boundary; and
issuing a notification of a change in service associated with crossing the predefined service boundary.

Abstract
A system and method for determining the availability of a mobile communications device on a network based on a prediction that the device will cross a peer-defined service boundary. The service boundary may be the periphery of a region in which the received signal strength is stronger than a minimum value, or the periphery of a region in which a particular service provider'"'"'s signal is dominant. When the device is about 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 comprise a change in the presence status of the mobile communications device. The service boundary is defined using aggregated data from a plurality of mobile communications devices reporting the received signal strength at various geographic locations.

24. A mobile communications device for use in a system for determining the availability of a user in a network, the mobile communications device comprising:
-
a location module for determining the geographic location and velocity data of the mobile communications device; a memory for storing said geographic location and velocity data, and for storing service coverage data comprising at least a segment of a predefined service boundary; a processor configured to predict, using stored service coverage data and geographic location and velocity data, that the mobile communications device will cross the predefined service boundary; and a processor and transmitter configured to issue a notification of a change in service associated with crossing the predefined service boundary. - View Dependent Claims (25, 26, 27, 28, 29, 30)

31. A coverage service for determining the availability of a user of a mobile communications device in a network, comprising:
-
a communications link for communicating with the network; a memory for storing service coverage data comprising at least a portion of a predefined network coverage area; a processor configured to receive tracking data sent from a mobile communications device, and further configured to predict, using stored service coverage data and received tracking data, that the mobile communications device will exit the predefined network coverage area, and further configured to generate a notification of a change in service associated with exiting the predefined network coverage area. - View Dependent Claims (32)
