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.

Examples are disclosed for executing a handoff profile for a hybrid mobile device. Communication link handoff logic may be executed by a processor component to detect an 802.11 network access point while in a communication session between a mobile device and a call server over a cellular communication link. The mobile device may register with the call server over the 802.11 network access point and establish a Voice-over Internet Protocol (VoIP) communication link between the mobile device and the call server. A test Real-time Transport Protocol (RTP) stream over the VoIP communication link between the mobile device and the call server may then be established. Data for discrete time intervals of the test RTP stream may be received, the data for each time interval comprising a plurality of VoIP communication link parameter values and fit to a statistical. The statistical model may be associated with a plurality of outcomes based on the VoIP communication link parameter values, the VoIP quality outcomes being either acceptable VoIP audio quality or poor VoIP audio quality. The communication session may then be handed off from the cellular communication link to the VoIP communication link when the outcome of the application of the statistical model to the received data is acceptable VoIP audio quality.

Techniques for executing a handoff profile between telecommunications networks

Examples are disclosed for executing a handoff profile for a mobile device. Communication link handoff logic may be executed by a processor to detect an 802.11 network access point and register the mobile device with a call server over the 802.11 network access point. Thereafter, a first timer may be initiated for a specified duration wherein the registration between the mobile device and the call server over the 802.11 network access point is maintained without interruption for the duration of the first timer. Upon successful expiration of the first timer, a second timer may be initiated for a specified duration wherein VoIP communication link parameters for the 802.11 link between the mobile device and the call server are deemed sufficient for the entire duration of the second timer. Upon successful expiration of the second timer, a handoff may be performed between the mobile device and the call server from the cellular communication link to the 802.11 link.

Examples are disclosed for user feedback to enable a handoff profile for a dual-mode hybrid mobile device. In some examples communication link handoff logic may be executed by the processor component to receive user feedback during a test voice call mediated with a call server, the user feedback pertaining to one or more Voice-over Internet Protocol (VoIP) communication link parameters for the communication link between the hybrid mobile device and the call server. The communication link parameters are correlated with a call quality threshold based on the user feedback and a handoff profile is established for the hybrid mobile device based on the call quality thresholds, the handoff profile operative to establish criteria for switching the VoIP communication link to a communication link over a different network.
