Abstract

Examples are disclosed for hosting a communication session between a hybrid mobile device and a second communication device in an Internet Protocol (IP) based packet data network. A communications server functions as a bridge service between the hybrid mobile device and the second communication device enabling the exchange of multiple concurrent IP packet data media streams over multiple different IP based networks between the hybrid mobile device and the communications server. The hybrid mobile device determines a packet quality for each corresponding packet in the multiple concurrent IP packet data media streams and creates a blended IP packet data media stream by selecting the highest quality packet from among the multiple concurrent IP packet data media streams. On the send side, the hybrid mobile device fully and partially encodes an IP packet data stream to be sent out over the multiple different IP based networks to the communications server.

First claim

What is claimed is:

1. A method comprising:
in a hybrid mobile device communicable with a communications server situated in an Internet Protocol (IP) based packet data network:
receiving multiple concurrent IP packet data media streams over corresponding multiple different communication links and network connections, at least one IP packet data media stream comprised of fully encoded IP data packets and at least one IP packet data media stream comprised of partially encoded IP data packets that contain less information than fully encoded IP data packets;
determining a packet quality for each corresponding packet in each time slot for the multiple concurrent IP packet data media streams, the highest quality packet being the one containing the most information; and
creating a blended IP packet data media stream by selecting the highest quality packet for each time slot from among the multiple concurrent IP packet data media streams.

2. The method of claim 1 , the different communication links and network connections comprising one of an 802.11 WiFi network connection, a cellular network connection, an 802.16 WiMax network connection, a wireless network connection operating within a frequency range of 100 MHz and 700 MHz, and a wireless network connection operating within a frequency range of 3.5 GHz and 3.7 GHz.

3. The method of claim 2 , the cellular network connection utilizing an IP protocol based on one of a General Packet Radio Service (GPRS), Enhanced Data for GSM Evolution (EDGE), Evolution-Data Optimized (EV-DO), High Speed Packet Data (HSPD), High Speed Downlink Packet Access (HSPDA), Long-Term Evolution (LTE), Voice-over Long-Term Evolution (VoLTE), Wideband Code Division Multiple Access (WCDMA), Universal Mobile Telecommunications System (UMTS), or High Rate Packet Data (HRPD).

4. The method of claim 1 , the IP packet data media streams comprising a Voice-over Internet Protocol (VoIP) media stream.

5. The method of claim 4 , the VoIP media stream comprised of Real-time Transport Protocol (RTP) packets.

6. The method of claim 1 , further comprising:
converting the blended IP packet data media stream to an analog audio signal; and
playing the analog audio signal through an audio out component of the hybrid mobile device.

7. A method comprising:
in a hybrid mobile device communicable with a communications server situated in an Internet Protocol (IP) based packet data network:
generating an IP packet data media stream;
fully encoding each generated packet into a first IP packet data media stream;
partially encoding each generated packet into a second IP packet data media stream; and
sending the first IP packet data media stream to the communications server over a first communication link and network connection
sending the second IP packet data media stream to the communications server over a second communication link and network connection, the second communication link and network connection different from the first communication link and network connection.

8. The method of claim 7 , the different communication links and network connections comprising one of an 802.11 WiFi network connection, a cellular network connection, an 802.16 WiMax network connection, a wireless network connection operating within a frequency range of 100 MHz and 700 MHz, and a wireless network connection operating within a frequency range of 3.5 GHz and 3.7 GHz.

9. The method of claim 8 , the cellular network connection utilizing an IP protocol based on one of a General Packet Radio Service (GPRS), Enhanced Data for GSM Evolution (EDGE), Evolution-Data Optimized (EV-DO), High Speed Packet Data (HSPD), High Speed Downlink Packet Access (HSPDA), Long-Term Evolution (LTE), Voice-over Long-Term Evolution (VoLTE), Wideband Code Division Multiple Access (WCDMA), Universal Mobile Telecommunications System (UMTS), or High Rate Packet Data (HRPD).

10. The method of claim 7 , the IP packet data media streams comprising a Voice-over Internet Protocol (VoIP) media stream.
