Apparatus for supporting the handover of a telecommunication session between a licensed wireless system and an unlicensed wireless system
First Claim
1. A mobile station comprising:
- a) a first wireless interface to access an unlicensed wireless communication network via an unlicensed wireless base station using an unlicensed radio frequency;
b) a second wireless interface to access a licensed wireless communication network using a licensed radio frequency;
c) a third interface to communicate with an unlicensed wireless network controller communicatively coupled to the base station via a broadband network;
d) circuits for handling a first set of messages transmitted over the second interface, the first set of messages comprising a measurement report sent to the licensed wireless communication network over the second interface, wherein the measurement report includes an Absolute Radio Frequency Channel Number (ARFCN) that is associated with the unlicensed wireless communication network and an indication that a cell associated with the unlicensed wireless communication network has a maximum signal quality; and
e) circuits for handling a second set of messages transmitted over the third interface to support handover of a communication session from the licensed wireless communication network to the unlicensed wireless communication network.

Abstract
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.
