Optimal use of multiple concurrent internet protocol (IP) data streams for voice communications
Examples are disclosed for mediating a voice communication session in which a communications server functions as a bridge service between a hybrid mobile device and a second endpoint. The communications server sends, over a downstream link, and receives, over an upstream link, an Internet Protocol (IP) packet data media stream representing the voice communication session over a WiFi IP data communication link to and from the hybrid mobile device. The communications server is also capable of sending, over a downstream link, and receiving, over an upstream link, a second IP packet data media stream representing the same voice communication session over a cellular IP data communication link to and from the hybrid mobile device. The communications server monitors the quality of service (QoS) of the IP packet data media stream as determined by multiple communication link parameters for the 802.11 WiFi network connection. When the communication link parameters dip below a specified QoS, the communications server interleaves a help packet into the downstream IP packet data media stream instructing the hybrid mobile device to begin streaming the IP packet data media stream representing the voice communication session over the upstream link of the cellular IP data communication link in addition to and in sync with the IP packet data media stream being sent over the upstream link of the WiFi IP data communication link.
