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.

What is claimed is: 1. A method comprising: from a network controller of a first communication network that communicatively couples a plurality of service regions of the first communication network to a licensed wireless second communication network, sending a ciphering mode message to a particular
What is claimed is: 1. A method comprising: from a network controller of a first communication network that communicatively couples a plurality of service regions of the first communication network to a licensed wireless second communication network, sending a ciphering mode message to a particular service region to indicate that ciphering is required for a telecommunication device at the particular service region, wherein the telecommunication device uses the ciphering mode message to enable ciphering when the communication session is handed over from the first communication network to the licensed wireless second communication network; and from the network controller, sending a channel activation message to the particular service region in order to facilitate activation of a channel for a communication session of the telecommunication device, wherein the activated channel uses Voice over Internet Protocol (VoIP). 2. The method of claim 1 further comprising receiving a ciphering mode complete message at the network controller after sending the ciphering mode message. 3. The method of claim 1, wherein said ciphering mode message comprises ciphering mode setting information for enabling ciphering when the communication session is subsequently handed over from the first communication network to the licensed wireless second communication network. 4. The method of claim 3, wherein said ciphering mode setting information is for storing on the telecommunication device. 5. The method of claim 1, wherein said ciphering mode message comprises an identity request. 6. The method of claim 1, wherein the first communication network is an unlicensed wireless network, wherein the telecommunication device is a dual-mode device comprising a first mode for communicating with the second communication network using licensed wireless frequencies and a second mode for communicating with the first communication network using unlicensed wireless frequencies. 7. The method of claim 1, wherein the communication session comprises voice communications. 8. The method of claim 1 further comprising establishing a secure link between the network controller and the service region. 9. The method of claim 8, wherein the secure link comprises a Transmission Control Protocol (TCP) session. 10. The method of claim 1 further comprising: at the network controller, establishing a Transmission Control Protocol over IP (TCP/IP) connection with the telecommunication device that is at the particular service region of the first communication network, wherein sending the ciphering mode message comprises sending the ciphering mode message over the TCP/IP connection to the telecommunication device. 11. A method comprising: at a network controller that communicatively couples a plurality of service regions of a first communication network to a licensed wireless second communication network, establishing a Transmission Control Protocol over IP (TCP/IP) connection with a telecommunication device that is at a particular service region of the first communication network; from the network controller, sending a ciphering mode message over the TCP/IP connection to the telecommunication device to indicate that ciphering is required for the telecommunication device at the particular service region; and at the network controller, receiving a response to the ciphering mode message from the telecommunication device over the TCP/IP connection, wherein the response indicates that the telecommunication device at the particular service region will enable ciphering when a communication session established by the telecommunication device is handed over from the first communication network over to the licensed wireless second communication network. 12. The method of claim 11, wherein the response is received in a ciphering mode complete message comprising information that identifies the telecommunication device. 13. The method of claim 11, wherein the ciphering mode message comprises an identity request for identifying the telecommunication device. 14. The method of claim 11, wherein said ciphering mode message comprises ciphering mode setting information for enabling ciphering when the communication session is subsequently handed over from the first communication network to the licensed wireless second communication network. 15. A method comprising: at a network controller that communicatively couples a plurality of service regions of a first communication network to a licensed wireless second communication network, establishing a Transmission Control Protocol over IP (TCP/IP) connection with a telecommunication device that is at a particular service region of the first communication network; receiving encryption information from the licensed wireless second communication network, wherein said encryption information is for enabling ciphering for a telecommunication device at a particular service region; and from the network controller, sending the encryption information to the telecommunication device over the TCP/IP connection, wherein the encryption information is for use by the telecommunication device at the particular service region to enable ciphering when a communication session is handed over from the first communication network over to the licensed wireless second communication network. 16. The method of claim 15, wherein the encryption information is received in a ciphering mode command from the licensed wireless second communication network. 17. The method of claim 16, wherein the ciphering mode command further comprises an identity request for identifying the telecommunication device. 18. The method of claim 15, wherein ciphering mode setting information is sent to the telecommunication device in a ciphering mode command. 19. The method of claim 15 further comprising at the network controller, receiving a ciphering mode complete message from the particular region, wherein said ciphering mode complete message comprises information that identifies the telecommunication device. 20. The method of claim 15 further comprising from the network controller, sending a ciphering mode complete message to the licensed wireless second communication network, wherein said ciphering mode complete message comprises information that identifies the telecommunication device.
