Intralink based session negotiation and media bit rate adaptation

A method comprising:

• receiving, by a first device from a second device, an offer message with an offered bit rate;
• determining, by the first device, a first bit rate supportable on a wireless channel in an unlicensed spectrum between the first device and a first tethered device;
• comparing, by the first device, the first bit rate with a second bit rate supportable by a connection between the first device and the second device that is at least partially across a licensed spectrum to determine a lower of the first bit rate or a second bit rate;
• determining, by the first device, a reply bit rate as a lower of:
• the first bit rate, the offered bit rate, and the second bit rate;
• and
• sending, by the first device to the second device, a reply message with the reply bit rate to apply to wireless communication across at least the first tethered device, the first device and the second device.

A first device comprising:

• at least one processor configured to:
• determine a channel quality of a wireless channel in an unlicensed spectrum between the first device and a first tethered device;
• determine a first bit rate supportable on the wireless channel according to the channel quality;
• compare the first bit rate with a second bit rate supportable by a connection between the first device and the second device that is at least partially across a licensed spectrum to determine a lower of the first bit rate or a second bit rate;
• send, to a second device, an offer message with an offered bit rate comprising the lower of the first bit rate or the second bit rate;
• and
• receive, from the second device, a reply message with a reply bit rate that is less than or equal to the offered bit rate, to apply to wireless communication across at least the first tethered device, the first device and the second device.
