1. A mobile station, comprising:
- a) a first wireless interface to access a licensed wireless communication network;
b) a second wireless interface to access an unlicensed wireless communication network via an unlicensed wireless base station using an unlicensed radio frequency;
c) a third interface to communicate with an unlicensed wireless network controller communicatively coupled to the base station via a broadband network; and
d) circuits for handling a set of unlicensed radio resource (RR) messages transmitted over the third interface to support releasing an unlicensed RR session between the mobile station and the unlicensed network controller, wherein the set of unlicensed RR messages includes;
an unlicensed RR release message received at the mobile station from the unlicensed network controller, said unlicensed RR release message for commanding the mobile station to release voice channels that the mobile station had allocated to the unlicensed RR session.

Abstract
An unlicensed wireless service is adapted to generate the interface protocols of a licensed wireless service to provide transparent transition of communication sessions between a licensed wireless service and an unlicensed wireless service. In one embodiment, a mobile station includes level 1, level 2, and level 3 protocols for licensed wireless service and an unlicensed wireless service. An indoor base station and indoor network controller provide protocol conversion for the unlicensed wireless service into a standard base station controller interface of the licensed wireless service.

5. An unlicensed wireless network controller to operate in an unlicensed wireless communication system comprising a first radio access network, the unlicensed network controller comprising:
-
a) a first network interface comprising a broadband access network; b) a second network interface through which messages are sent to and received from a mobile station via an access point communicatively coupled between the mobile station and the unlicensed network controller, the interface including a plurality of layers implemented over the broadband network interface; c) a third network interface, through which the unlicensed network controller may be connected to a telecommunications network employed by a licensed wireless communication system; and d) circuits for handling a set of unlicensed radio resource (RR) messages transmitted over the second interface to support releasing an unlicensed RR session between the mobile station and the unlicensed network controller, wherein the set of unlicensed RR messages includes; an unlicensed RR release message sent from the unlicensed network controller to command the mobile station to release the unlicensed RR session. - View Dependent Claims (6)
