Abstract
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.
