Method and apparatus for supporting the handover of a telecommunication session between a licensed wireless system and an unlicensed wireless system
First Claim
1. A method for registering a mobile station and handing over a communication session from a licensed wireless communication system to an unlicensed wireless communication system, the unlicensed wireless communication system comprising an indoor system server for communicatively coupling the unlicensed wireless communication system to the licensed wireless communication system, the method comprising:
- at the mobile station, establishing the communication session with the licensed wireless communication system;
at the mobile station, establishing a connection with the unlicensed wireless communication system through the indoor system server while maintaining the communication session with the licensed wireless communication system;
sending a registration message from the mobile station to the indoor system server to register the mobile station with the unlicensed wireless communication system;
registering the mobile station with the unlicensed wireless communication system; and
after registering the mobile station with the unlicensed wireless communication system, handing over the communication session from the licensed wireless communication system to the unlicensed wireless communication system.

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.
