Methods, architectures, apparatuses and systems for associating usims with a dualsteer device

A wireless transmit/receive unit (WTRU) that is communicatively coupled to a wireless network, the WTRU comprising:

• a first user equipment (UE);
• a second UE;
• a first universal subscriber identity module (USIM);
• a second USIM, wherein the first UE is associated with the first USIM and the second UE is associated with the second USIM,
• a processor;
• and
• a transceiver coupled to the processor, wherein the WTRU is to:
• detect a trigger to associate the first USIM and the second USIM with the WTRU;
• based on detecting the trigger, send by the first UE, to the wireless network, a first message indicating DualSteer capabilities for the WTRU based on the first UE and on the second UE;
• receive by the first UE, from the wireless network, a second message indicating authorized DualSteer capabilities, and association information for the first USIM and the second USIM with respect to the WTRU;
• send, by the first UE to the second UE, a third message indicating the association information and the authorized DualSteer capabilities;
• send, by the second UE to the wireless network, a fourth message indicating the association information;
• receive, from the wireless network, a fifth message indicating a time duration during which an association between the first USIM and the second USIM with the WTRU is valid;
• and
• perform DualSteer functions based on the time duration and on the authorized DualSteer capabilities.

• receive, from the second UE, a fourth message indicating the association information;
• authorize a time duration during which an association between the first USIM and the second USIM with the WTRU is valid;
• and
• send a fifth message indicating the authorized time duration, wherein the WTRU is to perform DualSteer functions based on the time duration and on the authorized DualSteer capabilities.
