System for transmitting streaming media content to wireless subscriber stations
A radio access system receives packets from a local source of streaming media content via a local connection and from remote packet sources via a remote network. The radio access system communicates with a subscriber station via an air interface that includes an uplink and a downlink. A packet classifier in the radio access system maps packets having the subscriber station's IP address as destination address to the subscriber station's downlink. The subscriber station communicates with a content controller via the remote network to request selected streaming media content. The content controller instructs the radio access system to convey the selected streaming media content from the local source to the subscriber station. In response, the packet classifier maps the packets containing the selected streaming media content to a downlink (either the original downlink or a new one) for transmission to the subscriber station.
1. A system for conveying content to a subscriber station, said system comprising:
a radio access system for wirelessly communicating with said subscriber station;
a remote network;
a local content source for transmitting streaming media content to said radio access system via a local connection, wherein said local connection does not extend through said remote network; and
a content controller in communication with said radio access system via said remote network, wherein said content controller is configured to (i) exchange messages with said subscriber station via said remote network and radio access system, wherein said messages include descriptions of requested streaming media content and transport parameters to be used for delivering said requested streaming media content, said transport parameters including an Internet Protocol (IP) address and port number that will receive said requested streaming media content and (ii) after exchanging said messages, send one or more control signals to said radio access system, wherein said one or more control signals instruct said radio access system to convey said requested streaming media content from said local content source to said subscriber station, and wherein said one or more control signals identify said IP address and port number for receiving said requested streaming media content.
2. The system of claim 1 , wherein said radio access system comprises a base station.
3. The system of claim 1 , wherein said local content source comprises a satellite receiver.
4. The system of claim 1 , further comprising a radio access network, wherein said radio access network communicatively couples said radio access system and said remote network.
5. The system of claim 4 , further comprising a gateway, wherein said gateway communicatively couples said radio access network and said remote network.
6. The system of claim 5 , wherein said radio access network comprises an access service network, and wherein said gateway comprises an access service network gateway.
7. The system of claim 5 , wherein said radio access network comprises a base station controller and a packet control function, and wherein said gateway comprises a packet data serving node.
8. The system of claim 1 , wherein said messages are Session Initiation Protocol (SIP) messages.
9. The system of claim 8 , wherein said SIP messages include a SIP INVITE message transmitted by said subscriber station and a SIP 200 OK message transmitted by said content controller.
10. The system of claim 8 , wherein said descriptions of requested streaming media content and transport parameters to be used for delivering said requested streaming media content are Session Description Protocol (SDP) descriptions.
