Abstract: A method for offloading a video portion of a video call form a cellular network to a WLAN is provided. The method can include a wireless communication device participating in a video call with a remote device over a connection between the wireless communication device and a cellular network. The video call can include a first video stream carried over a first bearer on the cellular network and an audio stream carried over a second bearer on the cellular network. The method can further include the wireless communication device establishing a connection between the wireless communication device and a WLAN; performing a call setup procedure with the remote device to establish a second video stream over the WLAN; terminating the first video stream; and using the second video stream and the audio stream to continue the video call.

Abstract: QoS based uplink data buffering while TTI bundling is enabled by a wireless user equipment (UE) device. The UE may establish a packet-switched connection with a network via a wireless link. The UE may receive, at a media access control (MAC) layer, an indication to enable TTI bundling. The UE may selectively buffer uplink data at an application layer based on the indication to enable TTI bundling. The uplink data may be buffered selectively based on Quality of Service (QoS) considerations. Uplink transmissions may subsequently be performed using TTI bundling.
Abstract translation: 基于QoS的上行链路数据缓冲，而TTI绑定由无线用户设备（UE）设备启用。 UE可以经由无线链路与网络建立分组交换连接。 在媒体接入控制（MAC）层，UE可以接收启用TTI绑定的指示。 基于用于启用TTI绑定的指示，UE可以选择性地缓冲应用层上的上行链路数据。 可以基于服务质量（QoS）考虑来选择性地缓冲上行链路数据。 随后可以使用TTI捆绑来执行上行链路传输。

Abstract: A method for transitioning a video call is provided. The method can include a wireless communication device participating in a video call with a remote communication device via a first video call session established over a connection between the wireless communication device and a first cellular network. The video call can include a packet switched video stream carried over a first bearer and an audio stream carried over a second bearer. The method can further include the wireless communication device determining a degradation in a connection quality for the first cellular network; transitioning to a legacy cellular network having a circuit switched domain in response to the degradation in connection quality for the first cellular network; establishing a second video call session on the legacy cellular network; and using the second video call session to continue the video call on the legacy cellular network.

Abstract: A communications system may include at least a first user equipment (UE) device and a second UE device that communicate with one or more hosts via a cellular network and a call routing server. The first UE and the second UE may be paired and may convey peer-to-peer (P2P) signals between each other when in close proximity. The first UE may communicate with the cellular network using a Mobile Station International Subscriber Directory Number (MSISDN). The MSISDN may, as one example, be shared between the first UE and the second UE. In response to a trigger condition associated with the second UE moving out of proximity to the first UE and/or a user input, communication with the cellular network using the MSISDN may switch from the first UE to the second UE. This may be reversed when the second UE moves back into proximity to the first UE.
