Abstract

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.

Claims22

Dependent claims

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, and exchanges the respective pseudorandom numbers as the temporary device ID's via the NFC communications link,
request authorization to establish a wireless link between said first wireless transceiver and said second wireless transceiver,
exchange permanent device address ID's between first and second wireless transceivers identifying an address of respective first and second wireless communications devices upon receiving the authorization and based upon the temporary device ID, and
establish the wireless link between said first wireless transceiver and said second wireless transceiver based upon the permanent device address ID's of each of the wireless communications devices.
