Abstract:
1. A method for identifying an appropriate public safety answering point for a traveling mobile unit, the method comprising: establishing communication between a telematics service provider and the traveling mobile unit; receiving data from the traveling mobile unit at the telematics service provider, the data including at least then-current speed, then-current direction of travel and then-current position of the traveling mobile unit; predicting, for the traveling mobile unit, at the telematics service provider upon recognition and analysis of the data, at least two positions of the traveling mobile unit during a future planned communication between the traveling mobile unit and a public safety answering point or at a future time when the traveling mobile unit is likely to contact a public safety answering point; assigning, via the telematics service provider, a success factor to each of the at least two predicted positions; identifying, via the telematics service provider and for the traveling mobile unit, at least two appropriate public safety answering points based on each of the at least two predicted positions of the traveling mobile unit; assigning, by the telematics service provider, a success factor to each of the at least two identified appropriate public safety answering points; and establishing, from the telematics service provider, communication between the traveling mobile unit and one of the at least two identified appropriate public safety answering points, the appropriate public safety answering point being chosen based on the success factors assigned to each of the at least two identified appropriate public safety answering points; wherein one of the at least two predicted positions of the traveling mobile unit is in a first public safety answering point boundary, wherein an other of the at least two predicted positions of the traveling mobile unit is in a second public safety answering point boundary, and wherein assigning the success factor to each of the at least two identified appropriate public safety answering points includes: approximating a time it will take the traveling mobile unit to leave the first public safety answering point boundary and enter the second public safety answering point boundary; approximating a time it will take for establishing the communication between the traveling mobile unit and the one of the at least two identified appropriate public safety answering points; and from the approximations, determining which of the public safety answering point boundaries the traveling mobile unit will be in during the establishing of the communication.
