Network controller messaging for ciphering in an unlicensed wireless communication system
First Claim
Patent Images
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).

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.

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. - View Dependent Claims (12, 13, 14)

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. - View Dependent Claims (16, 17, 18, 19, 20)
