Abstract

Systems, methods, and instrumentalities are disclosed to control an inter user equipment transfer (IUT). A first user equipment (UE) may control an inter user equipment transfer (IUT) associated with a communication flow currently terminated at the first UE. The first UE may receive an indication of an environment change. An evaluation of an IUT policy may be performed in response to the environment change. It may be determined that a second UE is preferred to receive the communication flow. An IUT operation may be performed in relation to the communication flow. For example, the communication flow may be transferred from the first UE to a second UE.

Claims

1. A method to control an inter user equipment transfer (IUT), the method comprising:

receiving an indication of an environment change;

evaluating an IUT policy by a first user equipment (UE) in response to the indication of the environment change;

determining that a second UE is preferred to receive a communication flow; and

performing an IUT operation relating to the communication flow.

2. The method of claim 1, wherein the JUT operation is at least one of a transfer, an addition, or a replication.

3. The method of claim 1, wherein the environment change is at least one of:

a location change, a network entry, a network exit, a time period expiration, or a user action.

4. The method of claim 1, further comprising receiving a confirmation from a user relating to the IUT operation.

5. The method of claim 1, further comprising one of:

downloading the IUT policy from an access network discovery and selection function or defining and storing the IUT policy locally.

6. The method of claim 1, wherein the JUT operation is a transfer of the communication flow to the second UE, and wherein the transfer is designated as a user-initiated transfer, and wherein the user-initiated transfer designation indicates that the second UE is not to transfer the communication flow back to the first UE based on one or more IUT policies.

7. The method of claim 1, wherein the JUT policy includes one or more of:

a prioritized list of UEs, one or more types of media to which the IUT policy applies, a time period during which the IUT policy applies, a geographical area to which the IUT policy applies, or a network area to which the IUT policy applies.

8. The method of claim 1, wherein the JUT policy includes digital rights management (DRM) policy information, and wherein the DRM policy information includes one or more of the following:

a list of UEs that are able to receive DRM protected content, a maximum number of transfers associated with the communication flow, or a maximum number of transfers associated with a UE.

9. A first user equipment (UE) to control an inter user equipment transfer (IUT), the first UE configured, at least in part, to:

receive an indication of an environment change;

evaluate an IUT policy in response to the indication of the environment change;

determine that a second UE is preferred to receive a communication flow; and

perform an IUT operation relating to the communication flow.

10. The first UE of claim 9, wherein the IUT operation is at least one of a transfer, an addition, or a replication.

11. The first UE of claim 9, wherein the environment change is at least one of:

a location change, a network entry, a network exit, a time period expiration, or a user action.

12. The first UE of claim 9, further configured to receive a confirmation from a user relating to the IUT operation.

13. The first UE of claim 9, further configured to download the IUT policy from an access network discovery and selection function or define and store the IUT policy locally.

14. The first UE of claim 9, wherein the IUT operation is a transfer of the communication flow to the second UE, and wherein the transfer is designated as a user-initiated transfer, and wherein the user-initiated transfer designation indicates that the second UE is not to transfer the communication flow back to the first UE based on one or more IUT policies.

15. The first UE of claim 9, wherein the IUT policy includes one or more of:

a prioritized list of UEs, one or more types of media to which the IUT policy applies, a time period during which the IUT policy applies, a geographical area to which the IUT policy applies, or a network area to which the IUT policy applies.

16. The first UE of claim 9, wherein the IUT policy includes digital rights management (DRM) policy information, and wherein the DRM policy information includes one or more of the following:

a list of UEs that are able to receive DRM protected content, a maximum number of transfers associated with the communication flow, or a maximum number of transfers associated with a UE.
