Network controller messaging for channel activation in an unlicensed wireless communication system
First Claim
Patent Images
1. A method comprising:
- at 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, establishing a Transmission Control Protocol over Internet Protocol (TCP/IP) connection between the network controller and a telecommunication device that is at a particular service region of the first communication network;
from the network controller, sending a channel activation message to the telecommunication device over the TCP/IP connection;
through an activated channel, receiving at the network controller communication session data from the telecommunication device for routing to the licensed wireless second communication network; and
from the network controller, sending a release message to the telecommunication device at the particular service region over the TCP/IP connection, said release message causing the telecommunication device to terminate a communication session by releasing the activated channel.

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.

14. A method comprising:
-
a) 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 first message to page a telecommunication device in a particular service region; and b) from the network controller, sending to the particular service region a second message to activate a Voice over Internet Protocol (VoIP) communication channel between the network controller and the telecommunication device, wherein through the activated VoIP communication channel, the network controller receives communication session data from the telecommunication device for routing to the licensed wireless second communication network. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22)

23. In a communication system comprising a licensed wireless communication system and an unlicensed wireless communication system, the unlicensed wireless communication system having an unlicensed region served by an unlicensed network controller, the unlicensed wireless communication system having a service region that has an unlicensed wireless link with a telecommunication device using an unlicensed frequency, the licensed wireless communication system comprising a mobile switching center (MSC), a method for assigning a Voice over Internet Protocol (VoIP) voice bearer channel for the telecommunication device to access voice bearer services of the licensed wireless communication system via the unlicensed wireless communication system, the method comprising:
-
a) through the unlicensed wireless link, establishing at the unlicensed network controller a secure link with the telecommunication device; b) receiving an assignment request at the unlicensed network controller from the MSC; and c) at the unlicensed network controller, exchanging a set of unlicensed channel activation messages with the telecommunication device to assign the VoIP voice bearer channel, wherein the set of unlicensed channel activation messages includes; an activate channel message sent from the unlicensed network controller to the telecommunication device triggering an establishment of the VoIP voice bearer channel for the telecommunication device. - View Dependent Claims (24)

25. In a communication system that includes a licensed wireless communication system for communicatively connecting to a telecommunication device using a licensed wireless frequency and an unlicensed wireless communication system for communicatively connecting to the telecommunication device using an unlicensed wireless frequency, a computer readable storage medium of an unlicensed wireless network controller, said computer readable medium storing a computer program for execution by said unlicensed wireless network controller, said computer program comprising sets of instructions for:
-
a) connecting to a service region, said service region communicatively coupled to the telecommunication device using the unlicensed wireless frequency; and b) generating, transmitting, and processing a set of unlicensed messages to support assigning a Voice over Internet Protocol (VoIP) voice bearer channel for the telecommunication device to access voice bearer services of the licensed wireless communication system via the unlicensed wireless communication system, wherein the set of unlicensed messages comprises; an activate channel message sent by the unlicensed network controller and received at the telecommunication device, wherein the receipt of the activate channel message by the telecommunication device triggers an establishment of the VoIP voice bearer channel for the telecommunication device. - View Dependent Claims (26, 27)
