摘要： 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.

摘要： Wireless devices, networks and methods may operate to have a wireless device cause a base station to trigger voice call continuity handovers responsive to the quality of the cellular radio link in addition to the base station triggering such handovers based on location or mobility. Furthermore, wireless communication devices may also perform monitoring of multiple buffers operating within the wireless communication device and associated with different respective communication layers, in addition to monitoring the quality of the cellular radio link, to perform intelligent dropping/discarding and/or scheduling of packets at the wireless communications device. Any one or more of these features may improve the ability of the wireless communications device to achieve stated Voice over Long Term Evolution (VoLTE) performance benchmarks in the context of the realities of current VoLTE networks.

摘要： Reducing power consumption for cellular broadcast communication by a wireless device. A cellular communication channel for cellular broadcast messages may be monitored in a discontinuous manner according to specified cellular broadcast scheduling periods. Between each pair of cellular broadcast scheduling periods, the wireless device may operate in a reduced power state. During each cellular broadcast scheduling period, at least a cellular broadcast scheduling message may be received. If all scheduled cellular broadcast messages are received prior to an end of a cellular broadcast scheduling period, the wireless device may operate in the reduced power state for the remainder of that cellular broadcast scheduling period after all scheduled cellular broadcast messages are received.
