Mobile wireless communications device establishing wireless communication links based upon near field communication and related methods
View Patent ↗A wireless communications system may include first and second mobile wireless communications devices each comprising a respective input device, wireless transceiver, near-field communication (NFC) transceiver, and controller coupled to the input device, wireless transceiver and NFC transceiver. At least one of the controllers may be configured to establish an NFC communications link between the NFC transceivers when the first and second mobile wireless communications devices are in proximity, provide a temporary device identifier (ID) via the NFC communications link, request authorization to establish a wireless link between the wireless transceivers, provide a permanent device ID upon receiving the authorization and based upon the temporary device ID, and establish the wireless link between the wireless transceivers based upon the permanent device ID.
1. A wireless communications system comprising:
a first mobile wireless communications device comprising a first input device, a first wireless transceiver, a first near-field communication (NFC) transceiver, and a first controller coupled to said first input device, said first wireless transceiver and said first NFC transceiver; and
a second mobile wireless communications device comprising a second input device, a second wireless transceiver, a second NFC transceiver, and a second controller coupled to said second input device, said second wireless transceiver and said second NFC transceiver;
wherein said first controller and said second controller are configured to
establish an NFC communications link between said first NFC transceiver and said second NFC transceiver when said first mobile wireless communications device and second mobile wireless communications device are in proximity, and each controller generates a pseudorandom number as a temporary device identifier (ID) corresponding to a temporary Bluetooth name for each device and exchanges the respective pseudorandom numbers as the temporary device ID's via the NFC communications link,
and in response to exchanging the temporary device ID's, displaying an authorization menu on a display and requesting authorization using the display to establish a wireless link between said first wireless transceiver and said second wireless transceiver,
said first and second wireless transceivers are configured to exchange permanent device address ID's identifying an address of respective first and second mobile wireless communications devices upon receiving the authorization, and
establish the wireless link between said first wireless transceiver and said second wireless transceiver based upon the permanent device address ID's of the first and second wireless transceivers.
2. The wireless communications system of claim 1 wherein each of said first wireless transceiver and said second wireless transceiver comprises a Personal Area Network (PAN) transceiver.
3. The wireless communications system of claim 1 wherein each of said first wireless transceiver and said second wireless transceiver comprises a Bluetooth transceiver.
4. The wireless communications system of claim 1 wherein the permanent device address ID comprises a Media Access Control (MAC) address.
5. The wireless communications system of claim 1 wherein at least one of said first input device or said second input device comprises an input key.
6. The wireless communications system of claim 1 wherein at least one of said first input device or said second input device comprises a touchscreen display.
7. The wireless communications system of claim 1 wherein at least one of said first controller and said second controller is further configured to:
exchange data via the wireless link and terminate the wireless link upon a conclusion of the data exchange; and
purge the permanent device address ID upon termination of the wireless link.
8. The wireless communications system of claim 1 wherein at least one of said first controller and said second controller is configured to request authorization to establish the wireless link between said first wireless transceiver and said second wireless transceiver via respective input devices.
9. A wireless communications method for a first mobile wireless communications device comprising a first input device, a first wireless transceiver, a first near-field communication (NFC) transceiver, and a first controller coupled to the first input device, and a second mobile wireless communications device comprising a second input device, a second wireless transceiver, a second NFC transceiver and a second controller coupled to the second input device, the method comprising:
establishing an NFC communications link between the first NFC transceiver and the second NFC transceiver when the first mobile wireless communications device and second mobile wireless communications device are in proximity and each controller generating a pseudorandom number as a temporary device identifier (ID) corresponding to a temporary Bluetooth name and exchanging the respective pseudorandom numbers as the temporary device ID's via the NFC communications link;
and in response to exchanging the temporary device ID's, displaying an authorization menu on a display and requesting an authorization using the display to establish a wireless link between the first wireless transceiver and the second wireless transceiver;
exchanging permanent device address ID's for respective first and second mobile wireless communications devices upon receiving the authorization and based upon the temporary device ID; and
establishing the wireless link between the first wireless transceiver and the second wireless transceiver based upon the permanent device address ID's of each of the mobile wireless communications devices.
10. The method of claim 9 wherein each of the first wireless transceiver and the second wireless transceiver comprises a Bluetooth transceiver.
11. The method of claim 9 wherein the permanent device address ID comprises a Media Access Control (MAC) address.
12. The wireless communications system of claim 9 wherein at least one of said first controller and said second controller is configured to request authorization to establish the wireless link between said first wireless transceiver and said second wireless transceiver via respective input devices.
13. The method of claim 9 wherein at least one of the first input device or the second input device comprises an input key.
14. The method of claim 9 wherein at least one of the first input device or the second input device comprises a touchscreen display.
15. The method of claim 9 further comprising:
exchanging data via the wireless link and terminating the wireless link upon a conclusion of the data exchange; and
purging the permanent device address ID upon termination of the wireless link.
16. The method of claim 9 wherein the first mobile wireless communications device comprises a first cellular transceiver; and wherein the second mobile wireless communications device comprises a second cellular transceiver.
17. The method of claim 9 wherein each of the first wireless transceiver and the second wireless transceiver comprises a Personal Area Network (PAN) transceiver.
