Abstract
A method of integrating a licensed wireless system and an unlicensed wireless system includes establishing a communication session through a landline. The communication session is linked to a subscriber device through an unlicensed wireless system servicing an unlicensed wireless system service area. An indication is received that the subscriber device is moving from the unlicensed wireless system service area into a licensed wireless system service area. Without disrupting the communication session, the communication session is automatically transitioned from the unlicensed wireless system to a licensed wireless system servicing the licensed wireless system service area. Similarly, a call initiated on the licensed wireless system is automatically transitioned to the unlicensed wireless system when the subscriber device enters the unlicensed wireless system service area.
