Mobile station messaging for ciphering in an unlicensed wireless communication system
First Claim
Patent Images
1. A method of operating a telecommunication device, the method comprising:
- providing a first communication layer for communicating with a licensed first communication system through a licensed first wireless communication channel; and
providing a second communication layer for communicating with a second communication system through a second wireless communication channel,wherein communicating with the second communication system comprises;
receiving a ciphering mode message through the second wireless communication channel from a network controller of the second communication system, said ciphering mode message comprising ciphering mode setting information for enabling ciphering when a communication session is handed over from the second communication system to the licensed first communication system; and
receiving a channel activation message through the second wireless communication channel from the network controller of the second communication system in order to facilitate activation of a channel for the communication session of the telecommunication device, wherein the activated channel uses Voice over Internet Protocol (VoIP).

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.

9. A telecommunication device operable with a licensed first wireless communication network and a second wireless communication network, the telecommunication device comprising:
-
a first module to implement protocols for facilitating communications with the licensed first wireless communication network; and a second module to implement protocols for facilitating communications with the second wireless communication network by processing a ciphering mode message received over a Transmission Control Protocol over IP (TCP/IP) connection from a network controller of the second wireless communication network, wherein the ciphering mode message indicates that ciphering is required for the telecommunication device when a communication session of the telecommunication device is handed over from the second wireless communication network to the licensed first wireless communication network. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A computer readable storage medium of a telecommunication device, said computer readable storage medium storing a computer program for execution by said telecommunication device, said computer program comprising:
-
a set of instructions for establishing a first communication layer for communicating with a licensed first communication system through a licensed first wireless communication channel; and a set of instructions for establishing a second communication layer for communicating with a second communication system through a second wireless communication channel, wherein the second wireless communication channel uses Voice over Internet Protocol (VoIP), wherein communicating with the second communication system comprises receiving a ciphering mode message through the second wireless communication channel from a network controller of the second communication system, said ciphering mode message comprising ciphering mode setting information for enabling ciphering when a communication session is handed over from the second communication system to the licensed first communication system. - View Dependent Claims (18, 19, 20)
