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.

Claims

1-20. -20. (canceled)

21. A method of operating a dual-mode telecommunication device, the method comprising:

providing a first communication layer for communicating with a licensed communication system through a licensed wireless communication channel; and

providing a second communication layer for communicating with an unlicensed communication system through an unlicensed wireless communication channel,

wherein communicating with the unlicensed communication system comprises receiving a ciphering mode message received through the unlicensed wireless communication channel from a network controller of the unlicensed communication system, said ciphering mode message comprising ciphering mode setting information for enabling ciphering when a communication session is handed over from the unlicensed communication system to the licensed communication system.

22. The method of claim 21, wherein the ciphering mode message further comprises an identity request for identifying the telecommunication device.

23. The method of claim 21, wherein communicating with the unlicensed communication system further comprises sending a ciphering mode complete message to the network controller to indicate that the telecommunication device will enable ciphering when the communication session established is handed over.

24. The method of claim 23, wherein the ciphering mode complete message comprises information that identifies the telecommunication device.

25. The method of claim 21, wherein the network controller communicatively couples a plurality of service regions of the unlicensed communication system to the licensed communication system, wherein the plurality of service regions comprises a particular service region in which the telecommunication device operates.

26. The method of claim 21, wherein communicating with the unlicensed communication system further comprises receiving a paging message for establishing the communication session through the network controller.

27. The method of claim 21, wherein the telecommunication device comprises at least one of a wireless telephone, a smart phone, a personal digital assistant, and a mobile computer.

28. The method of claim 21, wherein the communication session comprises voice communications.

29. A dual-mode telecommunication device operable with a licensed wireless communication network and an unlicensed wireless communication network, the telecommunication device comprising:

a first module to implement protocols for facilitating communications with the licensed wireless communication network; and

a second module to implement protocols for facilitating communications with the unlicensed wireless communication network by processing a ciphering mode message received from a network controller of the unlicensed 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 unlicensed wireless communication network to the licensed wireless communication network.

30. The telecommunication device of claim 29, wherein the second module is further for facilitating communications with the unlicensed wireless communication network by generating a response to the ciphering mode message to send to the network controller to indicate that the telecommunication device will enable ciphering when the communication session is handed over from the unlicensed wireless communication network to the licensed wireless communication network.

31. The telecommunication device of claim 30, wherein the response to the ciphering mode message comprises a ciphering mode complete message comprising information that identifies the telecommunication device.

32. The telecommunication device of claim 29, wherein said ciphering mode message comprises ciphering mode setting information for enabling ciphering when the communication session is subsequently handed over from the unlicensed wireless communication network to the licensed wireless communication network.

33. The telecommunication device of claim 32, wherein the second module is further for storing the ciphering mode setting information on the telecommunication device to be used when the communication session is handed over from the unlicensed wireless communication network to the licensed wireless communication network.

34. The telecommunication device of claim 29, wherein the communication session comprises voice communications.

35. The telecommunication device of claim 29, wherein the telecommunication device comprises at least one of a wireless telephone, a smart phone, a personal digital assistant, and a mobile computer.

36. The telecommunication device of claim 29 further comprising a processor and a memory storing the first module and the second module, the memory operatively connected to the processor and including computer instructions for executing the first module and the second module.

37. A computer readable storage medium of a telecommunications device, said computer readable storage medium storing a computer program for execution by said telecommunications device, said computer program comprising:

a set of instructions for establishing a first communication layer for communicating with a licensed communication system through a licensed wireless communication channel; and

a set of instructions for establishing a second communication layer for communicating with an unlicensed communication system through an unlicensed wireless communication channel,

wherein communicating with the unlicensed communication system comprises receiving a ciphering mode message received through the unlicensed wireless communication channel from a network controller of the unlicensed communication system, said ciphering mode message comprising ciphering mode setting information for enabling ciphering when a communication session is handed over from the unlicensed communication system to the licensed communication system.

38. The computer readable storage medium of claim 37, wherein the ciphering mode message further comprises an identity request for identifying the telecommunication device.

39. The computer readable storage medium of claim 37, wherein the computer program further comprises a set of instructions for sending a ciphering mode complete message to the network controller to indicate that the telecommunication device will enable ciphering when the communication session established is handed over.

40. The computer readable storage medium of claim 39, wherein the ciphering mode complete message comprises information that identifies the telecommunication device.
