Abstract

A server for integrating an unlicensed wireless communication system and a licensed wireless communication system includes a network interface card, a licensed wireless network interface card, and a processor connected to the network interface card and the licensed wireless network interface card. A memory is connected to the processor. The memory stores instructions to identify when a subscriber device is entering a service region of a selected unlicensed wireless communication base station. Additional instructions coordinate the routing of a current communication session on a licensed wireless communication system to the selected unlicensed wireless communication base station.

Claims
