Abstract: Techniques described provide for transferring calls between a first user equipment (UE) and a second UE. One implementation may include receiving a request to transfer a call, which has been established between the first UE and a third party device, to be between a second UE and the third party device. Location information for the first and second UEs may be received. A determination may be made to determine whether the first and second UE are in proximity to each other. In the event that a determination is made that the first and second UE are in proximity to each other, the established call may be transferred from the first UE to the second UE. Other aspects and features are also claimed and described.

Abstract: A configuration is disclosed to enable a UE to preempt SRVCC by triggering a handover to a Wi-Fi network. The apparatus determines whether a Wi-Fi cell is viable as a first target cell, from a plurality of target cells, serving the UE to continue the active transmission on the Wi-Fi cell. The apparatus extends a TTT timer length based at least in part on the determination that the Wi-Fi cell is viable as the target cell serving the UE to continue the active transmission on the Wi-Fi cell. The apparatus initiates a handover to the Wi-Fi cell from the first network prior to the expiration of a TTT timer and prior to the first network initiating a handover to a second target cell, from the plurality of target cells, on a second network.

Abstract: A system and method for performing video telephony (VT) is disclosed. In one example, there is provided an apparatus having a transceiver configured to receive VT data and information indicating a switch from a first display to a second display from a network. The apparatus also includes a decoder operatively coupled to the transceiver and configured to decode the VT data, a memory comprising a coded picture buffer (CPB) configured to store the decoded VT data, and a processor operatively coupled to the transceiver, the decoder, and the memory. The processor is configured to, in response to receiving the information indicating a switch from a first display to a second display, instruct the transceiver to transmit a request for an I-frame to the network.

Abstract: A system and method for rate-adaptation of a video telephony (VT) session is disclosed. In one example, there is provided a method that includes receiving a first information set indicative of a start of a handover of a device from a first Radio Access Technology (RAT) to a second RAT. The method further includes receiving a second information set indicative of an end of the handover. The method further includes adjusting a rate-adaptation protocol for the VT session based at least in part on the first and second information sets.
