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.

21. A method for ciphering configuration in a communication system comprising a licensed wireless communication system and an unlicensed wireless communication system, wherein the unlicensed wireless communication system comprises an unlicensed network controller, the method comprising:
sending a base station system management application part (BSSMAP) cipher mode command from the licensed wireless communication system to the unlicensed network controller to indicate that ciphering is required. - View Dependent Claims (22, 23, 24, 25, 26, 27)

28. An unlicensed wireless network controller to operate in an unlicensed wireless communication system comprising a first radio access network, the network controller comprising:
-
a) a first network interface comprising a broadband access network;
b) a second network interface through which messages are to be transmitted to and from a mobile station via an access point communicatively coupled between the MS and the network controller, the interface including a plurality of layers implemented over the broadband network interface;
c) a third network interface, through which the network controller may be connected to a telecommunications network employed by a licensed wireless communication system; and
d) circuits for handling a set of messages exchanged with the licensed wireless communication network and a set of unlicensed radio resource (RR) messages transmitted over the second interface to support ciphering configuration of a mobile station, wherein the set of messages exchanged with the licensed wireless communication network includes;
a base station system management application part (BSSMAP) cipher mode command sent from the licensed wireless communication system to the unlicensed network controller to indicate that ciphering is required. - View Dependent Claims (29, 30, 31, 32, 35, 36, 37)

33. A machine readable medium comprising a set of instructions, which when executed by an unlicensed network controller through which a mobile stations has an unlicensed radio resource (RR) connection to an unlicensed wireless communication system, causes the network controller to exchange a set of messages with a licensed wireless communication system and exchange a set of unlicensed radio resource (RR) messages with the mobile station to support ciphering configuration of the mobile station, wherein the set of messages exchanged with the licensed wireless communication network includes:
a base station system management application part (BSSMAP) cipher mode command received from the licensed wireless communication system to the unlicensed network controller to indicate that ciphering is required. - View Dependent Claims (34)
