1. A method of managing licensed and unlicensed communications over a cellular protocol, comprising the steps of:

  • (a) wirelessly transmitting a communication session request from a wireless device to a wireless carrier system using the cellular protocol, wherein the communication session request is transmitted over a licensed communications frequency band as a part of an attach procedure;

    (b) receiving a response at the wireless device from the wireless carrier system as a part of the attach procedure, wherein an inspection of information in the response provides an indication that either the wireless carrier system is providing a communication session using the licensed communications frequency band or the wireless carrier system is providing a communication session using an unlicensed communications frequency band;

    (c) determining whether to establish communications via the licensed communications frequency band or the unlicensed communications frequency band based on the content of the communications that are to be carried out with the wireless carrier system; and

    (d) establishing communications from the wireless device via the wireless carrier system based on whether the wireless carrier system is providing cellular communications via the licensed communications frequency band or the unlicensed communications frequency band, wherein the establishing step includes;

    when it is determined to establish communications via the licensed communications frequency band and when it is determined that the wireless carrier system is providing cellular communications via the unlicensed communications frequency band, then repeating the attach procedure including steps (a) and (b) until the wireless carrier system provides cellular communications via the licensed communications frequency band.
