Abstract

Methods of wireless communication and wireless transmit/receive units (WTRUs) are described. A WTRU includes a processor. The processor determines a location of the WTRU and whether an application is available to the WTRU based on the determined location of the WTRU. On a condition that the application is determined to be available to the WTRU based on the determined location of the WTRU, the processor initiates a registration to an application service hosting the application.

Claims

1. A method of wireless communication comprising:

a wireless transmit/receive unit (WTRU) receiving a system information block (SIB) broadcast by an eNodeB;

the WTRU determining that proximity detection for localized applications are supported by the eNodeB based on the received SIB;

the WTRU determining a location of the WTRU and sending the location to the eNodeB;

the WTRU receiving in response to the sending of the determined location a proximity detection associated with a localized application; and

in response to the proximity detection, the WTRU receiving discovery signals from a second WTRU for use in establishing device-to-device communications between the WTRU and the second WTRU;

wherein the localized application is received from the second WTRU via device-to-device communications;

wherein the device-to-device communications are WiFi communications offloaded from a cellular network.

2. The method of claim 1, wherein the WTRU determines the location of the WTRU based on at least one of global positioning system (GPS) positioning, assisted GPS (A-GPS) positioning, observed time difference of arrival (OTDOA) positioning, determining whether the WTRU is located in a sector of a given cell, determining whether the WTRU is located in a given cell associated with a given cell identity, determining whether the WTRU is located within a given cell area, determining whether the WTRU is located within a given tracking area, a system information element broadcast in a call, a multimedia broadcast multimedia services (MBMS) session available in a given cell, a Wifi parameter, determining whether the WTRU is located in a mobility management entity (MME) area of a given cell, or determining whether the WTRU receives discovery-related signals from another WTRU.

3. The method of claim 1, wherein the WTRU initiates access to the application by initiating a registration to the application using at least one of a network access server (NAS) service request or an NAS ATTACH procedure.

4. The method of claim 1, wherein the application is provided by the second WTRU via peer-to-peer communications, and the second WTRU is a Wifi access point.

5. The method of claim 1, wherein the WTRU determines whether the application is available to the WTRU based on the determined location of the WTRU by:

receiving localized application information (LAI) relating to at least one application from an application service associated with the application; and

determining whether the at least one application is available to the WTRU based on the received LAI.

6. The method of claim 5, wherein the LAI includes information about at least a location area of the at least one application.

7. The method of claim 1, further comprising:

the WTRU periodically determining whether the application continues to be available to the WTRU based on the determined location of the WTRU; and

on a condition that the WTRU determines that the application is no longer available to the WTRU, discontinuing communications with an application server associated with the application.

8. The method of claim 7, wherein the discontinuing communications with the application server includes initiating de-registration from the application.

9. The method of claim 1, wherein the SIB is transmitted by a long term evolution (LTE) eNodeB and the received discovery signals are IEEE 802.11 discovery signals.

10. The method of claim 9, wherein the LTE eNodeB sends the WTRU information for use by the WTRU to receive the IEEE 802.11 discovery signals.

11. The method of claim 1, wherein the WTRU periodically transmits determined locations to the eNodeB and the received proximity detection is in response to at least one of the transmitted determined locations.

12. The method of claim 1, wherein the WTRU receives broadcast or dedicated transmissions indicating resources for receiving the discovery signals associated with the localized application.

13. The method of claim 1, wherein the received discover signals are long term evolution (LTE) signals.

14. A wireless transmit/receive unit (WTRU) comprising:

a receiver configured to receive a system information block (SIB) broadcast by an eNodeB;

a processor configured to;

determine that proximity detection for localized applications are supported by the eNodeB based on the received SIB;

determine a location of the WTRU;

a transmitter configured to send the location to the eNodeB;

in response to the proximity detection, the receiver configured to receive discovery signals from a second WTRU for use in establishing device-to-device communications between the WTRU and the second WTRU;

wherein the localized application is received from the second WTRU via device-to-device communications;

wherein the device-to-device communications are WiFi communications offloaded from a cellular network.

15. The WTRU of claim 14, wherein the processor is configured to determine the location of the WTRU based on at least one of global positioning system (GPS) positioning, assisted GPS (A-GPS) positioning, observed time difference of arrival (OTDOA) positioning, determining whether the WTRU is located in a sector of a given cell, determining whether the WTRU is located in a given cell associated with a given cell identity, determining whether the WTRU is located within a given cell area, determining whether the WTRU is located within a given tracking area, a system information element broadcast in a call, a multimedia broadcast multimedia services (MBMS) session available in a given cell, a Wifi parameter, determining whether the WTRU is located in a mobility management entity (MME) area of a given cell, or determining whether the WTRU receives discovery-related signals from another WTRU.

16. The WTRU of claim 14, wherein the processor is configured to initiate access to an application server by initiating a registration to the application server using at least one of a network access server (NAS) service request or an NAS ATTACH procedure.

17. The WTRU of claim 14, wherein the application is provided by the second WTRU.

18. The WTRU of claim 14, wherein the transmitter is configured to transmit the SIB by a long term evolution (LTE) eNodeB and the received discovery signals are IEEE 802.11 discovery signals.
