Abstract

See full text

The invention discloses a wireless communication handset comprising licensed wireless communication signal processing circuitry and unlicensed wireless communication signal processing circuitry. The invention further discloses a control circuit connected to both the licensed wireless communication signal processing circuitry and the unlicensed wireless communication signal processing circuitry, and a computer readable memory for directing the control circuit to function in a specified manner. This memory includes instructions to formulate a measurement report containing signal strength information that corresponds to the strength of a signal received through the unlicensed wireless communication signal processing circuitry. The measurement report also contains a request to transfer a wireless communication session from a licensed wireless system to an unlicensed wireless system. The memory further includes instructions to transmit the measurement report to the licensed wireless system through the licensed wireless communication signal processing circuitry.
