OPTIMAL USE OF MULTIPLE CONCURRENT INTERNET PROTOCOL (IP) DATA STREAMS FOR VOICE COMMUNICATIONS

摘要

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.

1. A method of mediating a communication session between a hybrid mobile device and a second communication device endpoint in which a communications server functions as a bridge service between the hybrid mobile device and the second communication device endpoint for a voice communication session, wherein the communications server is currently sending, over a downstream link, and receiving, over an upstream link, a WiFi Internet Protocol (IP) packet data media stream representing the voice communication session over a WiFi IP data communication link comprising an 802.11 wireless fidelity (WiFi) network connection to and from the hybrid mobile device and the communications server is capable of sending, over a downstream link, and receiving, over an upstream link, a cellular IP packet data media stream representing the voice communication session over a cellular IP data communication link to and from the hybrid mobile device, the method comprising:
in the communications server:
monitoring the quality of service (QoS) of the upstream WiFi IP packet data media stream as determined by multiple communication link parameters for the 802.11 WiFi network connection; andwhen the QoS of the upstream WiFi IP packet data media stream dips below a specified threshold, interleaving a help packet into the downstream cellular IP packet data media stream, the help packet including an instruction for the hybrid mobile device to begin streaming the IP packet data media stream representing the voice communication session over the upstream cellular link in addition to and in sync with the IP packet data media stream representing the voice communication session over the upstream link of the WiFi IP data communication link.
