Apparatus and method for extending the coverage area of a licensed wireless communication system using an unlicensed wireless communication system
First Claim
1. A system comprising:
- a mobile station operable to communicate with a telecommunications network using a licensed wireless communication channel serviced by the telecommunications network in a first mode and an unlicensed wireless communication channel in a second mode;
a base station communicably coupled to the mobile station via the unlicensed wireless communication channel; and
a network controller communicably coupled to the base station and adapted to communicate with the telecommunications network, wherein the mobile station includes call control to control a communication session with the telecommunications network through the network controller using the unlicensed wireless communication channel by exchanging call control information with the network controller via one or more messages having the A1 protocol message format.
