Device and method for redirecting a wireless communication link based on location
First Claim
1. A wireless communication device in a vehicle for maintaining a communication link according to either a first wireless communication protocol or a second wireless communication protocol, the device comprising:
- a first network access device that operates according to the first wireless communication protocol;
a second network access device that operates according to the second wireless communication protocol;
a positioning unit for determining a location of the vehicle;
a memory that stores a database of geographic coverage areas for maintaining the communication link according to the first wireless communication protocol; and
a controller that switches a communication link from operating according to the second wireless communication protocol to operating according to the first wireless communication protocol when the location of the vehicle falls within the geographic coverage area of the first wireless communication protocol.

Abstract
A wireless communication device (22) in a vehicle (26) for maintaining a communication link according to either a first wireless communication protocol or a second wireless communication protocol. The device comprises a first network access device (42), a second network access device (44), a positioning unit (66), a memory (64), and a controller (56). The first network access device (42) operates according to a first wireless communication protocol. The second network access device (44) operates according to a second wireless communication protocol. The positioning device (66) is used for determining a location of the vehicle (26). The memory (64) stores a database of geographic coverage areas for maintaining the communication link according to the first wireless communication protocol. The controller (56) switches or otherwise redirects a communication link from operating according to the second wireless communication protocol to operating according to the first wireless communication protocol when the location of the vehicle (26) falls within the geographic coverage area of the first wireless communication protocol.

17. A method in a wireless communication device of a vehicle, the wireless communication device having a first network access device and a second network access device, the first network access device operating according to a first wireless communication protocol, the second network access device operating according to a second wireless communication protocol, the method comprising the steps of:
-
determining whether the wireless communication device is communicating through the second network access device;
determining the location of the vehicle when it is determined that the wireless communication device is communicating through the second network access device;
accessing a memory in the wireless communication device to obtain information regarding geographic coverage areas for communicating with remote base stations that operate according to the first wireless communication protocol; and
redirecting a communication from the second network access device to the first network access device based on the location of the vehicle and based on the information regarding the geographic coverage areas for communicating with the remote base stations that operate according to the first wireless communication protocol. - View Dependent Claims (18, 19, 20)
