Abstract

A wireless communications system includes a wireless communications network and a plurality of wireless communications devices. The wireless communications devices are each configured to communicate via the wireless communications network. At least one of the plurality of wireless communications devices has a portable housing, a wireless transceiver carried by the portable housing, and a wireless-based, availability detector carried by the portable housing. A processor is carried by the portable housing and is configured to determine a first availability status based upon the NFC device at a first time. The processor is further configured to activate the wireless-based, availability detector based upon the NFC device to thereby determine a second availability status based upon the wireless-based, availability detector at a second time after the first time. The processor is additionally configured to communicate the first and second availability status to the wireless communications network via the wireless transceiver.

Claims

1. A wireless communications system comprising:

a wireless communications network; and

a plurality of wireless communications devices, each configured to communicate via said wireless communications network, at least one of said plurality of wireless communications devices comprising

a portable housing,

a wireless transceiver carried by said portable housing,

a Near Field Communications (NFC) device carried by said portable housing,

a wireless-based, availability detector carried by said portable housing, and

a processor carried by said portable housing and configured to

determine a first availability status based upon said NFC device at a first time,

activate said wireless-based, availability detector based upon said NFC device to thereby determine a second availability status based upon said wireless-based, availability detector at a second time after the first time, and

communicate the first availability status and the second availability status to said wireless communications network via said wireless transceiver.

2. The wireless communications system according to claim 1, wherein said wireless communications network is configured to communicate the first availability status and the second availability status to at least one other wireless communications device.

3. The wireless communications system according to claim 1, wherein said wireless communications network is configured to communicate the first availability status and the second availability status to a social networking site.

4. The wireless communications system according to claim 1, further comprising at least one NFC tag cooperating with said NFC device carried by said portable housing;

and wherein the first availability status is based upon a momentary proximity between said at least one NFC tag and said NFC device carried by said portable housing.

5. The wireless communications system according to claim 1, wherein said wireless-based, availability detector comprises a Global Positioning Satellite (GPS) receiver so that the second availability status is based upon at least one geospatial position of said wireless communications device.

6. The wireless communications system according to claim 5, wherein said at least one wireless communications device further comprises at least one input device carried by said portable housing;

and wherein said wireless-based, availability detector is configured to cooperate with said at least one input device to permit association of the at least one geospatial position with the second availability status.

7. The wireless communications system according to claim 1, wherein said wireless-based, availability detector comprises a Bluetooth device.

8. The wireless communications system according to claim 7, further comprising at least one other Bluetooth device cooperating with said Bluetooth device;

and wherein the second availability status is based upon a communications link between said Bluetooth device and said at least one other Bluetooth device.

9. The wireless communications system according to claim 1, further comprising an accelerometer carried by said housing and coupled to said processor;

and wherein said processor is also configured to determine the second availability status based upon said accelerometer.

10. A wireless communications device for communication with a wireless communications network comprising:

a portable housing;

a wireless transceiver carried by said portable housing;

a Near Field Communications (NFC) device carried by said portable housing;

a wireless-based, availability detector carried by said portable housing; and

a processor carried by said portable housing and configured to

determine a first availability status based upon said NFC device at a first time,

activate said wireless-based, availability detector based upon said NFC device to thereby determine a second availability status based upon said wireless-based, availability detector at a second time after the first time, and

communicate the first availability status and the second availability status to said wireless communications network via said wireless transceiver.

11. The wireless communications device according to claim 10, wherein said wireless-based, availability detector comprises a Global Positioning Satellite (GPS) receiver;

and wherein the second availability status is based upon at least one geospatial position of said wireless communications device.

12. The wireless communications device according to claim 11, wherein said at least one wireless communications device further comprises at least one input device carried by said portable housing;

and wherein said wireless-based, availability detector is configured to cooperate with said at least one input device to permit association of the at least one geospatial position with the second availability status.

13. The wireless communications device according to claim 10, wherein said wireless-based, availability detector comprises a Bluetooth device.

14. The wireless communications system according to claim 13, wherein the second availability status is based upon a communications link between said Bluetooth device and at least one other Bluetooth device.

15. The wireless communications device according to claim 13, further comprising an accelerometer carried by said housing and coupled to said processor;

and wherein said processor is also configured to determine the second availability status based upon said accelerometer.

16. A method of using a wireless communications device comprising a processor, and a wireless transceiver, a Near Field Communications (NFC) device, and a wireless-based availability detector coupled thereto, the method comprising:

determining, using the processor, a first availability status based upon the NFC device at a first time;

activating, using the processor, the wireless-based, availability detector based upon the NFC device to thereby determine a second availability status based upon the wireless-based, availability detector at a second time after the first time; and

communicating the first availability status and the second availability status to a wireless communications network via the wireless transceiver.

17. The method according to claim 16, wherein the first availability status is based upon a momentary proximity between at least one external NFC tag and the NFC device.

18. The method according to claim 16, wherein the wireless-based, availability detector comprises a Global Positioning Satellite (GPS) receiver;

and wherein the second availability status is based upon at least one geospatial position of the wireless communications device.

19. The method according to claim 18, wherein the wireless-based, availability detector is configured to cooperate with at least one input device to permit association of the at least one geospatial position with the second availability status.

20. The method according to claim 16, wherein the wireless-based, availability detector comprises a Bluetooth device;

and wherein the second availability status is determined based upon a communications link between the Bluetooth device and at least one external Bluetooth device.

21. The method according to claim 16, wherein the second availability status is also determined based upon an accelerometer.
