Systems and methods for implementing handovers in a vehicle communication system
First Claim
1. A vehicle communication system comprising:
- a first communication system configured to communicate via first type of communication signal to at least one first remote communication system;
a second communication system configured to communicate via a second type of communication signal to at least one second remote communication system;
a controller located in a vehicle, configured to perform the following;
review a communication coverage map along a projected travel path of the vehicle;
assign a priority level to communication associated with the vehicle;
select between use of the first and second communication systems based on the priority level of the communication, a predicted percentage of time along the travel path with first or second communication system coverage, and an anticipated number of handovers between the first communication system and second communication system needed in a defined window of time; and
activate the selected communication system as the vehicle travels along the projected travel path.

Abstract
A vehicle communication system is provided. The vehicle communication system includes a first communication system, a second communication system and a controller. The first communication system is configured to communicate via first type of communication signal to at a least one first remote communication system. The second communication system is configured to communicate via a second type of communication signal to the at least one second remote communication system. The controller is configured to select between use of the first and second communication systems based on at least one of a predicted availability of first and second communication coverage during a travel route and an anticipated number of handovers needed in a defined window of time.

1. A vehicle communication system comprising:
-
a first communication system configured to communicate via first type of communication signal to at least one first remote communication system; a second communication system configured to communicate via a second type of communication signal to at least one second remote communication system; a controller located in a vehicle, configured to perform the following; review a communication coverage map along a projected travel path of the vehicle; assign a priority level to communication associated with the vehicle; select between use of the first and second communication systems based on the priority level of the communication, a predicted percentage of time along the travel path with first or second communication system coverage, and an anticipated number of handovers between the first communication system and second communication system needed in a defined window of time; and activate the selected communication system as the vehicle travels along the projected travel path. - View Dependent Claims (2, 3, 4, 5, 6, 7)

8. A method of operating a vehicle communication system having a first communication system and at least one second communication system, the method comprising:
-
reviewing a communication coverage map along a projected travel path for the vehicle; assigning a priority level to communication associated with the vehicle; determining an anticipated number of handovers between the first communication system and the second communication system in defined windows of time along the projected vehicle path based at least in part on the communication coverage map; comparing determined anticipated number of handovers in each defined window of time with a select threshold; activating the second communication system for each defined window of time along the vehicle path based on the priority level of the communication, a predicted percentage of time along the travel path with first communication system coverage or second communication system coverage, and whether the determined anticipated number of handovers for the defined window of time is less than the select threshold; and activating the first communication system for each defined window of time along the vehicle path based on the priority level of the communication, a predicted percentage of time along the travel path with first communication system coverage or second communication system coverage, and whether the determined anticipated number of handovers for the defined window of time is more than the select threshold. - View Dependent Claims (9, 10, 11, 12, 13)

14. A method of operating a vehicle communication system that includes a first communication system and at least one second communication system, the method comprising:
-
reviewing a communication coverage map along a projected travel path for a vehicle; assigning a priority level to communication associated with the vehicle; determining if the at least one first or second communication system will be used as the vehicle travels along the projected travel path based on the priority level of the communication, a predicted percentage of time along the travel path with the first or second communication coverage, and an anticipated number of handovers between the first communication system and second communication system needed in a defined window of time as the vehicle travels along the travel path; and activating the first or second communication system as the vehicle travels along the projected travel path based on the determining result. - View Dependent Claims (15, 16, 17, 18, 19)
