PAIRING DEVICES USING DATA EXCHANGED IN AN OUT-OF-BAND CHANNEL
First Claim
1. A method for pairing two devices comprising:
- while in-band transceivers of two devices, a first device and a second device, are in an off state and out-of-band transceivers of the two devices are in an on state, detecting that the two devices are within near field communication (NFC) range of each other;
conveying pairing information over an out-of-band channel requiring use of the out-of-band transceivers, wherein the out-of-band channel is a near field communication (NFC) channel, wherein the conveying of pairing information requires the first device to request at least one desired in-band service, to provide a device ID, and to provide an authorization code in a single message, wherein in response to the single message, the second device either denies in-band service or conveys resource use parameters for the in-band service and provides its device ID, wherein the resource use parameters and device ID are conveyed within a second single message;
responsive to the conveying of pairing information, the two devices turning on the in-band transceivers; and
pairing the two devices over an in-band channel, wherein the pairing uses the authorization code and the resource use parameters.

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.

6. A method for paring two devices comprising:
-
receiving at a device having an in-band transceiver and at least one out-of-band transceiver an out-of-band message, wherein the out-of-band message from a different device is received by the out-of-band transceiver, wherein the out-of-band message indicates a desired in-band service, an authorization code, and a device ID for the different device; determining whether the device is available to satisfy at the desired in-band service, which results in a positive or a negative determination; when the determination is negative, either ignoring the out-of-bound message or conveying a denial message to the different device via the out-of-band channel; when the determination is positive, conveying resource use parameters for the desired in-band service to the different device via the out-of-band channel; and establishing the in-bound service via an in-band channel at the device using the authorization code provided by the different device to establish the in-band service, wherein the different devices uses the resource use parameters conveyed in the out-of-bound channel to establish the in-band service. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17)

18. A method for pairing two devices comprising:
-
sending from a device having a BLUETOOTH transceiver and at least one Near Field Communication (NFC) transceiver, an out-of-band message via the NFC transceiver, wherein the out-of-band message indicates at least one desired BLUETOOTH service, provides a device ID of the device, and provides an authorization code for the device, wherein the BLUETOOTH transceiver is initially in an off state; receiving a response from a different device via the NFC transceiver, which provides an ID for the different device and resource use parameters for the BLUETOOTH service; changing the BLUETOOTH transceiver to an on state; establishing the at least one desired BLUETOOTH service with the different device using the resource use parameters, wherein the sending, receiving, turning, and establishing of the BLUETOOTH service occur without requiring any user interactions with the device other than bringing the device within near field communication range of the different device, wherein the different device does not send the device a complete list of BLUETOOTH services supported by the device but only provides the response that indicates resource use parameters for the desired BLUETOOTH service in an event that the different device is able to provide the desired BLUETOOTH service to the device, and wherein BLUETOOTH refers to a protocol compliant with BLUETOOTH version 2.1 protocol standards. - View Dependent Claims (19, 20)
