Abstract

An accessory for a user equipment (UE) is disclosed that includes a housing configured to be connected to the UE and accessory near field communication (NFC) circuit attached to the housing. The accessory NFC circuit includes an antenna, a charging circuit, and a transceiver circuit. The antenna is configured to inductively couple to signals emitted by a UE NFC circuit within the UE. The charging circuit is configured to output power provided by the inductive coupling through the antenna to the signals emitted by the UE NFC circuit. The transceiver circuit is configured to be powered by the charging circuit to transmit information to the UE NFC circuit that will be used by the UE to retrieve content stored on a content server and/or to authorize use of content stored on the UE. Related UEs and methods are disclosed.

8. The accessory of claim 1, wherein:

the accessory NFC circuit further comprises a counter configured to count power-on cycles of the accessory NFC circuit; and

the transceiver circuit is configured to select a universal resource locator (URL) address from among a group of URL addresses defined in the accessory NFC circuit based on the count and/or to select an activation code from among a group of activation codes defined in the accessory NFC circuit based on the count, and to transmit the selected URL address and/or the selected activation code to the UE NFC circuit for use by the UE to retrieve content stored on the content server and/or authorize use of content stored on the UE.

9. The accessory of claim 1, wherein:

the accessory NFC circuit further comprises a counter configured to count power-on cycles of the accessory NFC circuit; and

the transceiver circuit is configured to transmit a first universal resource locator (URL) address and/or to transmit a first activation code when the count satisfies a defined relationship to a threshold value, and to transmit a second URL address different from the first URL address and/or transmit a second activation code different from the first activation code when the count does not satisfy the defined relationship to the threshold value.

10. The accessory of claim 1, wherein:

the accessory NFC circuit further comprises a counter configured to count power-on cycles of the accessory NFC circuit; and

the transceiver circuit is configured to transmit the information when the count satisfies a defined relationship to a threshold value and to prevent transmission of the information when the count does not satisfy the defined relationship to the threshold value.

11. The accessory of claim 1, wherein:

the accessory NFC circuit further comprises a counter configured to count a number of different UEs that have powered the accessory NFC circuit to obtain information transmitted by the transmitter; and

the transceiver circuit is configured to select a universal resource locator (URL) address from among a group of URL addresses based on the count and/or to select an activation code from among a group of activation codes based on the count, and to transmit the selected URL address and/or the selected activation code to the UE NFC circuit that will be used by the UE to retrieve content stored on the content server and/or to authorize use of content stored on the UE.
