Methods and apparatuses for effecting handover in integrated wireless systems
First Claim
1. A method for effecting a handover in an integrated wireless system comprising an unlicensed first wireless system and a licensed second wireless system, the method comprising:
- receiving a handover request to perform the handover for a communication in progress, the handover being from the unlicensed first wireless system to the licensed second wireless system; and
prior to effecting the handover, changing a cell identifier associated with a user terminal in conjunction with the handover of the communication in progress, wherein the cell identifier is changed from a cell identifier of a first region of the unlicensed first wireless system to a cell identifier of a second region of the unlicensed first wireless system.

Abstract
Embodiments of the invention provide methods and apparatuses for effecting handover between the licensed and unlicensed portions of an integrated wireless network. For one embodiment, prior to hand out of a communication from the unlicensed wireless system (UWS), a cell identifier associated with a user terminal is changed from the cell identifier corresponding to the internet access point to the cell identifier corresponding to the unlicensed network controller. This allows the destination MSC of the licensed wireless system (LWS) to accept and fulfill a handover request from the UWS. In accordance with an alternative embodiment of the invention, after a hand in of a communication to the UWS, a cell identifier associated with the user terminal is changed from the cell identifier corresponding to the UNC to the cell identifier corresponding to the internet access point. This change allows providing location-based services to the UT being serviced by the UWS.
