Abstract

Systems, methods, and instrumentalities are disclosed to provide privacy for inter-user equipment transfer (IUT) subscribers and remote parties involved in sessions with IUT subscribers. A first UE may establish a session with a remote party. The first UE may seek to perform an IUT to a second UE. The first UE may send a first request for the IUT to a service centralization and continuity application server (SCC AS). The SCC AS may receive the first request and perform an authorization. The SCC AS may determine that the requested IUT is allowed for the session. The SCC AS may send a second request to the remote party indicating the requested IUT. The remote party may evaluate the second request and may accept or reject the second request.

Claims

1. A method for performing an inter user equipment transfer, the method comprising:

receiving an indication of a privacy preference for an inter user equipment transfer action;

receiving a first request for the inter user equipment transfer of a media component of a session;

in response to receiving the first request, determining that the requested inter user equipment transfer is allowed for the session, wherein determining that the requested inter user equipment transfer is allowed for the session comprises determining that the session is not subject to copyright-based digital rights management;

if the privacy preference indicates that a source of the media component of the session be made aware of an inter user equipment transfer performed on the session, sending a second request to the source of the media component indicating the requested inter user equipment transfer; and

receiving an acceptance of the requested inter user equipment transfer from the source of the media component.

2. The method of claim 1, wherein the second request indicates an identity relating to a user equipment that is a target of the requested inter user equipment transfer.

3. The method of claim 2, wherein the identity is a session initiation protocol identity.

4. The method of claim 1, wherein the second request comprises a modified session description protocol message comprising an attribute, wherein the attribute indicates an identity of a user equipment that is a target of the requested inter user equipment transfer.

5. The method of claim 1, further comprising sending a control message to the source of the media component for transfer of the media component to a user equipment that is a target of the requested inter user equipment transfer, wherein the control message is a modified session description protocol message.

11. The method of claim 1, further comprising receiving, during an initiation of the session, an indication of a restriction applicable to a component of the session.

12. The method of claim 11, wherein the restriction applies to at least one of a transfer or a replication of the component of the session.

13. The method of claim 11, wherein the indication of the restriction comprises an attribute applied to the component of the session.

14. The method of claim 11, wherein the indication of the restriction overrides the privacy preference.

19. The method of claim 1, wherein the indication of the privacy preference is provided by the source of the media component.

6. A service centralization and continuity application server, comprising:

a receiver configured to receive an indication of a privacy preference for an inter user equipment transfer action and to receive a first request for the inter user equipment transfer of a media component of a session;

a processor configured to, in response to receiving the first request, determine that the requested inter user equipment transfer is allowed for the session, wherein determining that the requested inter user equipment transfer is allowed for the session comprises determining that the session is not subject to copyright-based digital rights management; and

a transmitter configured to, if the privacy preference indicates that a source of the media component of the session may be made aware of an inter user equipment transfer performed on the session, send a second request to the source of the media component indicating the requested inter user equipment transfer; and

wherein the receiver is further configured to receive an acceptance of the requested inter user equipment transfer from the source of the media component.

7. The service centralization and continuity application server of claim 6, wherein the second request indicates an identity relating to a user equipment that is a target of the requested inter user equipment transfer.

8. The service centralization and continuity application server of claim 7, wherein the identity is a session initiation protocol identity.

9. The service centralization and continuity application server of claim 6, wherein the second request comprises a modified session description protocol message comprising an attribute, wherein the attribute indicates an identity of a user equipment that is a target of the requested inter user equipment transfer.

10. The service centralization and continuity application server of claim 6, wherein the transmitter is further configured to send a control message to the source of the media component for transfer of the media component to a user equipment that is a target of the requested inter user equipment transfer, wherein the control message is a modified session description protocol message.

15. The service centralization and continuity application server of claim 6, wherein the receiver is further configured to receive, during an initiation of the session, an indication of a restriction applicable to a component of the session.

16. The service centralization and continuity application server of claim 15, wherein the restriction applies to at least one of a transfer or a replication of the component of the session.

17. The service centralization and continuity application server of claim 15, wherein the indication of the restriction comprises an attribute applied to the component of the session.

18. The service centralization and continuity application server of claim 15, wherein the indication of the restriction overrides the privacy preference.

20. The service centralization and continuity application server of claim 6, wherein the indication of the privacy preference is provided by the source of the media component.
