Pairing devices using data exchanged in an out-of-band channel
Abstract:
Two devices (110, 120) can be determined to be within near field communication (NFC) range of each other. Pairing information for a service can be conveyed over an out-of-band channel (114, 124). The out-of-band channel can be a near field communication (NFC) channel. The service can be a Bluetooth service provided via an in-band (e.g., BLUETOOTH) channel (112, 122). The conveying of the pairing information can require the first device (110) to request at least one desired service, to provide a device ID, and to provide an authorization code in a single message (150). In response to the single message (150), the second device (120) can either deny the request (160, 162) or can convey resource use parameters for the desired service and an ID for the second device within a second single message (164). Pairing the two devices (110, 120) can require use of the authorization code and the resource use parameters.
