Abstract:
1. A method, comprising: receiving, by an intermediate network router comprising a processor, from a source gateway router streamed content associated with a broadcast video channel initiated by a mobile broadcast service center that provides broadcast video services, wherein the intermediate network router is coupled to a plurality of radio network controllers that control a plurality of base stations providing wireless services to each of a plurality of mobile communication devices, and wherein the plurality of base stations comprise a plurality of wireless base stations; routing, by the intermediate network router, over a first routing path the streamed content associated with the broadcast video channel to a first radio network controller of the plurality of radio network controllers for delivery to a first base station of the plurality of base stations that delivers the streamed content to a first mobile communication device of the plurality of mobile communication devices requesting content over the broadcast video channel and serviced by the first radio network controller; storing, by the intermediate network router, information indicating that the streamed content associated with the broadcast video channel is being delivered to the first radio network, wherein the information associated with the streamed content is added to a new channel bundle or existing channel bundle, and wherein the intermediate network router deletes or adds channel bundles from storage according to channel bundle changes initiated by the mobile broadcast service center to satisfy user content requests; receiving, by the intermediate network router, a request from a second radio network controller of the plurality of radio network controllers to deliver the streamed content associated with the broadcast video channel to a second mobile communication device of the plurality of mobile communication devices serviced by a second base station of the plurality of base stations coupled to the second radio network controller; determining, by the intermediate network router, that the streamed content associated with the broadcast video channel is being delivered to the first radio controller according to the stored information; determining, by the intermediate network router, that the request does not need to be routed to the source gateway or the mobile broadcast service center; and splitting, by the intermediate network router, the first routing path to create a second routing path for routing the streamed content associated with the broadcast video channel to the second radio network controller for delivery of the streamed content to the second base station for delivery to the second mobile communication device while continuing to route the streamed content associated with the broadcast video channel to the first radio network controller without interruption, wherein routing of the streamed content associated with the broadcast video channel to the second radio network controller is performed without informing the source gateway router or the mobile broadcast service center, and wherein the streamed content routed to the first radio network controller and to the second radio network controller constitutes a simulcast transmission of the streamed content associated with the broadcast video channel for simulcast delivery to the first mobile communication device and the second mobile communication device.
