Method and system for transmitting streaming media content to wireless subscriber stations
View Patent ↗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 radio access system, comprising:
a transceiver system for wirelessly transmitting data;
a plurality of data interfaces for receiving data packets, said data packets including first data packets and second data packets, said plurality of data interfaces including a first data interface for receiving said first data packets from a remote packet source via a first pathway and a second data interface for receiving said second data packets from a local packet source via a second pathway, wherein said first pathway extends through a gateway between said radio access system and a remote network and said second pathway does not extend through said gateway;
a packet classifier for mapping said first data packets and said second data packets to transport connections for wireless transmission to subscriber stations by said transceiver; and
a control interface for receiving control signals from an external controller in said remote network via said gateway, wherein said control signals control how said packet classifier maps said first data packets and said second data packets to said transport connections, wherein said control signals include an instruction to convey streaming media content from said local packet source to a first subscriber station, wherein said first subscriber station receives said first data packets from said remote packet source via a first transport connection, and wherein said packet classifier is configured, in response to said instruction, to change its mapping for said first transport connection so as to map said second data packets to said first transport connection instead of said first data packets.
2. The radio access system of claim 1 , wherein said local packet source comprises a satellite receiver.
3. The radio access system of claim 1 , wherein said first data packets contain signaling for establishing a streaming media session and said second data packets contain streaming media content.
4. The radio access system of claim 1 , wherein said packet classifier is part of an 802.16 convergence sublayer.
5. The radio access system of claim 1 , wherein said transceiver system, said control interface, said plurality of data interfaces, and said packet classifier are in a base station.
6. The radio access system of claim 1 , wherein said first pathway extends through a home agent and said second pathway does not extend through said home agent, and wherein said home agent supports Mobile IP.
