4. The method of claim 1 , further comprising initiating a call on the second subscription using the extracted caller ID after sending the full set of UE capability information.

5. The method of claim 1 , wherein generating a report of less than a full set of UE capability information comprises generating the report having a first size less than a second size of a full report of the full set of UE capability information.

6. A user equipment (UE) for reporting UE capability information to a network, the UE comprising:

a transceiver configured to transmit a connection setup signal for a second subscription during a tune away from an active voice call on a first subscription, wherein the transceiver is configured to transmit the connection setup signal in response to receiving a paging message from the network for the second subscription during the tune away;

at least one processor coupled to the transceiver via a bus, the at least one processor configured to extract a caller identification (ID) associated with the connection setup for the second subscription during the tune away from the voice call on the first subscription; and to generate a report of less than a full set of UE capability information for sending to the network for the second subscription during the connection setup; and to initiate a transmission to the network for sending the full set of UE capability information for the second subscription in response to the voice call on the first subscription ending; and

a user interface for displaying the extracted caller ID;

wherein the transceiver is further configured to transmit a connection release signal for ending the voice call on the first subscription.

7. The UE of claim 6 , wherein the transceiver is further configured to receive a signal from the network with information including the caller ID, to tune back to the voice call on the first subscription after receiving the signal, and to send a release connection for the second subscription after the extraction of the caller ID.

8. The UE of claim 6 , wherein the at least one processor is further configured to format an information element for the report of less than the full set of UE capability information to exclude one or more enhanced UE capabilities.

9. The UE of claim 6 , wherein the at least one processor is further configured to initiate a call on the second subscription using the extracted caller ID after the sending of the full set of UE capability information and the transceiver is further configured to send a signal to the network to establish a connection for the call on the second subscription.

10. The UE of claim 6 , wherein the at least one processor generates the report of less than a full set of UE capability information having a first size less than a second size of a full report of the full set of UE capability information.

11. A user equipment (UE) for reporting UE capability information to a network, the UE comprising:

means for receiving a paging message for a second subscription during a tune away from an active voice call on a first subscription;

means for initiating a connection procedure to the second subscription in response to the received paging message;

means for transmitting a connection setup signal for the second subscription during the tune away from the active voice call on the first subscription;

means for extracting a caller identification (ID) associated with the connection setup for the second subscription during the tune away from the voice call on the first subscription;

means for generating a report of less than a full set of UE capability information for sending to the network for the second subscription during the connection setup;

means for sending the full set of UE capability information to the network for the second subscription in response to the voice call on the first subscription ending;

means for displaying the extracted caller ID; and

means for transmitting a connection release signal for ending the voice call on the first subscription.

12. The UE of claim 11 , further comprising:

means for receiving a signal from the network with information including the caller ID, for tuning back to the voice call on the first subscription after receiving the signal, and for sending a release connection for the second subscription after the extraction of the caller ID.

13. The UE of claim 11 further comprising:

means for formatting an information element for the report of less than the full set of UE capability information to exclude one or more enhanced UE capabilities.

14. The UE of claim 11 , further comprising:

means for initiating a call on the second subscription using the extracted caller ID after the sending of the full set of UE capability information and

means for sending a signal to the network to establish a connection for the call on the second subscription.

15. The UE of claim 11 , wherein the means for generating a report of less than a full set of UE capability information further generates the report having a first size less than a second size of a full report of the full set of UE capability information.
