Abstract

Location and other status information may be communicated between Proximity Service (ProSe) users. A ProSe function may retrieve a ProSe WTRU'"'"'s location data from SLP and provide it to a monitoring WTRU via a ProSe discovery procedure or EPC-level ProSe discovery procedure. A ProSe function may retrieve a ProSe WTRU'"'"'s location data from a ProSe WTRU and provide it to monitoring WTRUs via a ProSe discovery procedure. A ProSe WTRU may broadcast its location and/or other status information in a discovery message. A ProSe function may encrypt the location and/or other status information for encryption before broadcast. A ProSe WTRU may send its location and/or other status information via a user plane to another ProSe WTRU or ProSe group. A ProSe function may verify whether a WTRU is permitted to disclose and/or process information (e.g., location information) and may indicate to a WTRU whether to disclose information, e.g., before the information is disclosed, and/or whether to process the information.

Claims

1. A method for communicating status information, the method comprising:

receiving a match report from a first wireless transmit/receive unit (WTRU) at a proximity service (ProSe) function, the match report comprising a request for location information associated with a second WTRU;

determining whether the first WTRU is authorized to receive the location information associated with the second WTRU;

if the first WTRU is authorized to receive the location information associated with the second WTRU, determining the location information associated with the second WTRU; and

sending a match report acknowledgement to the first WTRU, the match report acknowledgement comprising the location information of the second WTRU.

3. The method of claim 1, wherein the location information is received from a secure user plane location (SUPL) location platform (SLP).

5. The method of claim 1, wherein the match report acknowledgement is sent to the first WTRU in an evolved packet core (EPC) level ProSe discovery procedure.

6. The method of claim 1, wherein the location information is sent in a discovery message.

7. The method of claim 1, wherein the location information is sent using a PC5 interface.

8. The method of claim 1, wherein the location information is encrypted.

9. The method of claim 1, further comprising determining whether the first WTRU is authorized to receive the location information from the second WTRU based on a home subscriber server (HSS) subscription.

10. The method of claim 1, further comprising requesting authorization from a ProSe application server (PAS) for the location information to be received by the first WTRU.

2. (canceled)

4. (canceled)

11. A public land mobile network (PLMN) device comprising:

a memory to store processor-executable instructions; and

a processor to execute the processor-executable instructions to;

receive a discovery request message from a first wireless transmit/receive unit (WTRU) at a proximity service (ProSe) function, the match report comprising a request for location information associated with a second WTRU;

determine whether the first WTRU is authorized to receive the location information associated with the second WTRU;

if the first WTRU is authorized to receive the location information associated with the second WTRU, determining the location information associated with the second WTRU; and

send a match report acknowledgement to the first WTRU, the match report acknowledgement comprising the location information of the second WTRU.

13. The PLMN device of claim 11,

wherein the location information is received from a secure user plane location (SUPL) location platform (SLP).

15. The PLMN device of claim 11, wherein the location information is sent to the first WTRU in an evolved packet core (EPC) level ProSe discovery procedure.

16. The PLMN device of claim 11, wherein the location information is sent in a discovery message or using a PC5 interface.

17. The PLMN device of claim 11, wherein the status information is encrypted.

18. The PLMN device of claim 11, the processor further configured to determine whether the first WTRU is authorized to send the status information to the second WTRU based on a home subscriber server (HSS) subscription.

19. The PLMN device of claim 11, the processor further configured to request authorization from a ProSe application server (PAS) for the location information to be received by the first WTRU.

12. (canceled)

14. (canceled)

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

a processor configured to;

send a match report to a proximity service (ProSe) function, the match report comprising a request for location information associated with a second WTRU;

receive a match report acknowledgement comprising the location information associated with the second WTRU on a condition that the second WTRU is authorized to disclose the location information to the first WTRU; and

determining a proximity of the first WTRU to the second WTRU.

21. The first WTRU of claim 20, the processor being configured to determine the proximity of the first WTRU to the second WTRU using an evolved packet core (EPC) level discovery procedure.

22. The first WTRU of claim 20, the EPC level discovery procedure comprising a secure user plane (SUPL) procedure.
