Establishing communication between devices using close proximity protocol

摘要

Methods and devices detect a near field communication (NFC) from a near field wireless communication device of an external computerized device, using an apparatus near field wireless communication device. Based on detecting the NFC, the methods/devices generate random identification and security codes, transmit the identification code and the security code from the apparatus near field wireless communication device to the device near field wireless communication device, and place the previously inactive apparatus wide-range wireless communication device in an active state. In response, the method receives the security code from a wide-range wireless communication device of the external computerized device using the apparatus wide-range wireless communication device. Then the method establishes a network communication session only between the external computerized device and the apparatus based on receiving the security code.

主权项

1. An apparatus comprising:
a processor; an apparatus near field wireless communication device operatively connected to said processor; and an apparatus wide-range wireless communication device operatively connected to said processor, said apparatus near field wireless communication device and said apparatus wide-range wireless communication device using different communication mediums, said processor maintaining said apparatus wide-range wireless communication device in an inactive state and said apparatus near field wireless communication device in an active state based on no communications being received from external devices that are external to said apparatus, said apparatus near field wireless communication device detecting a near field communication (NFC) from an external device near field wireless communication device of an external computerized device, based on said detecting of said NFC from said external computerized device, said processor:
generating a random identification code and a random security code;transmitting said identification code and said security code from said apparatus near field wireless communication device to said device near field wireless communication device; andmaintaining said apparatus wide-range wireless communication device in an active state, said apparatus wide-range wireless communication device receiving said security code from an external device wide-range wireless communication device of said external computerized device, said processor establishing a network communication session only between said external computerized device and said apparatus using only said apparatus wide-range wireless communication device and said external device wide-range wireless communication device, based on said receiving of said security code, and said generating of said identification code and said security code comprising generating different identification codes and different said security codes for each different network communication session between said apparatus and different ones of said external devices, making each different identification code and each different said security code unique for each said different network communication session.
