Device and method for establishing a wireless communication link by a wireless communication device having more than one transceiver
First Claim
1. A wireless communication device comprising:
- a first transceiver that operates according to a first wireless communication protocol;
a second transceiver that operates according to a second wireless communication protocol;
a positioning unit for determining a location of the wireless communication device;
a memory that stores a database of the geographic coverage areas for communicating with remote base stations that operate according to the first wireless communication protocol; and
a controller that selects between the first transceiver and the second transceiver when initially attempting to establish a wireless communication link;
wherein the selection between the first transceiver and the second transceiver is based on the determined location of the wireless communication device from the positioning unit and the geographic coverage areas in the database that is stored in the memory.

Abstract
A wireless communication device (22) that comprises a first transceiver (40), a second transceiver (42), a positioning unit (44), a memory (46), and a controller (48). The first transceiver (40) operates according to a first wireless communication protocol. The second transceiver (42) operates according to a second wireless communication protocol. The positioning unit (44) determines a location of the wireless communication device (22). The memory (46) stores a database of the geographic coverage areas for communicating with remote base stations that operate according to the first wireless communication protocol. The controller (48) is configured to select between the first transceiver (40) and the second transceiver (42) when initially attempting to establish a wireless communication link. In particular, the selection between the first transceiver (40) and the second transceiver (42) is based on the determined location of the wireless communication device (22) from the positioning unit (44) and the geographic coverage areas in the database that is stored in the memory (46). There are also methods of performing these functions in the wireless communication device (22).

11. A wireless communication device comprising:
-
a first and second transceiver, each of the first and second transceivers operating according to a different wireless communication protocol;
a positioning unit for determining a location of the wireless communication device;
a memory that stores information regarding the geographic coverage areas for communicating with remote base stations that operate according to at least one of the wireless communication protocols; and
a means for selecting between the first and second transceivers when the wireless communication device needs to establish a wireless communication link, the selection means based on the location of the wireless communication device from the positioning unit and based on the information stored in the memory regarding the geographic coverage areas for communicating with remote base stations that operate according to at least one of the wireless communication protocols. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)

21. A method in a wireless communication device, the wireless communication device having a first transceiver and a second transceiver, each of the first and second transceivers operating according to a different wireless communication protocol, the method comprising the steps of:
-
determining whether a wireless communication link needs to be established by the wireless communication device;
determining the location of the wireless communication device when it is determined that a wireless communication link needs to be established;
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 at least one of the wireless communication protocols; and
selecting to establish the wireless communication link through either the first transceiver or the second transceiver based on the location of the wireless communication device and based on the information regarding the geographic coverage areas for communicating with the remote base stations that operate according to at least one of the wireless communication protocols. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29)
