Abstract

A network device receives, from a user device, an inquiry for a selected very-far field communication (VFC) tag and selects, from a group of available base stations, one or more particular base stations of a wireless access network from which to broadcast a tag query for the selected VFC tag. The network device inserts the tag query into a broadcast signal of each of the one or more particular base stations. The VFC tag receives the tag query and transmits a local response signal over a local wireless network. A mobile device within range of the local response signal processes the local response signal and forwards the local response signal to the network device as a tag response. The network device receives the tag response and sends an indication of the tag response to the user device.

Claims

1. A method, comprising:

selecting, by a network device and from a group of available base stations, one or more particular base stations of a wireless access network from which to broadcast a tag query for a selected very-far field communication (VFC) tag;

inserting, into a broadcast signal of each of the one or more particular base stations, the tag query;

receiving, by the network device and from a mobile device within range of a local wireless network signal of the selected VFC tag, a tag response that is prompted by the tag query and a local signal from the selected VFC tag, wherein the mobile device is different than the VFC tag; and

sending, by the network device and to a user device, an indication of the tag response.

2. The method of claim 1, further comprising:

detecting, by the selected VFC tag, the tag query; and

broadcasting, by the selected VFC tag, the local signal via the local wireless network that is different than the wireless access network.

3. The method of claim 2, further comprising:

receiving, by the mobile device, the local signal via the local wireless network; and

sending, by the mobile device, the tag response to the network device.

4. The method of claim 1, further comprising:

adding, by the mobile device, a location indication of the mobile device, to a local tag response from the selected VFC tag, to create the VFC tag response.

5. The method of claim 1, further comprising:

identifying expiration of a waiting period for receiving a response to the tag query;

selecting, from the group of available base stations, one or more other particular base stations of a wireless access network from which to re-broadcast the tag query; and

inserting, into a broadcast signal of each of the one or more other particular base stations, the tag query.

6. The method of claim 1, wherein inserting the tag query includes inserting a tag query symbol into a control channel of the wireless access network.

7. The method of claim 1, further comprising:

receiving, from the user device, an inquiry for the selected VFC tag.

8. The method of claim 1, further comprising:

storing, in a database, a record of the tag response, wherein the record includes the location information and time information.

9. The method of claim 1, further comprising:

forwarding, to one of a billing system, a payment system, or a third-party system, an indication of the tag response.

10. The method of claim 1, wherein sending the indication of the tag response includes:

providing the tag response via a short messaging service (SMS) message or an email message.

11. A system, comprising:

a very-far field communication (VFC) tag including;

a receiver to listen for a tag query provided via a wireless access network, and

a transmitter to provide a local signal, in response to the tag query, over a local wireless network that is different than the wireless access network;

a mobile device configured to;

receive the local signal from the VFC tag, and

send a tag response, based on the local signal, to a network device; and

the network device configured to;

select from a group of available base stations, a particular base station of the wireless access network from which to broadcast a tag query for the VFC tag,

cause insertion of the tag query into a broadcast signal associated with the particular base station,

receive the tag response from the mobile device, and

send, to a user device, an indication of the tag response.

12. The system of claim 11, wherein the VFC tag further comprises:

a power source, and

a controller to manage time intervals for listening by the receiver.

13. The system of claim 11, wherein the mobile device includes one of:

a smart phone,

a radiotelephone,

a personal communications system (PCS) terminal,

a personal digital assistant (PDA),

a wireless device,

a computer,

a global positioning system (GPS) device, or

a gaming device.

14. The system of claim 11, wherein the network device is further configured to:

receive, from the user device, registration information for the VFC tag, wherein the registration information includes contact information for the user device to receive the indication of the tag response.

15. The system of claim 11, wherein, when sending the tag response, the mobile device is further configured to:

add a location indication of the mobile device to information in the local signal to create the VFC tag response.

16. The system of claim 11, wherein the wireless access network is a cellular band network, and wherein the local wireless network is one of:

a WiFi protocol network, or

a Bluetooth protocol network.

17. A method, comprising:

receiving, by a mobile device and via a local wireless signal, a response message from a very-far field communication (VFC) tag, wherein the response message is responsive to a tag query provided through base station of a cellular network, and wherein the response message includes a unique identifier for the VFC tag;

adding, by the mobile device and to the response message, location information associated with the mobile device to create a tag response; and

sending, by the mobile device and to a network device beyond the range of the local wireless signal, the tag response.

18. The method of claim 17, wherein the location information includes one of:

Global Positioning System (GPS) coordinates,

cell-tower triangulation data, or

identification information of a fixed device with which the mobile device is in local communication.

19. The method of claim 17, further comprising:

receiving, from the network device, an application that includes a user interface to restrict sending of tag responses from the mobile device to sending only tag responses relating to particular VFC tags; and

determining, by the mobile device, that the unique identifier in the response message is from one of the particular VFC tags.

20. The method of claim 17, wherein the receiving, adding, and sending are performed by the mobile device without additional input from a user of the mobile device.
