发明名称 On-demand mobile wireless broadcast video delivery mechanism
摘要 A mobile broadcast service center and a mobile wireless network to deliver broadcast video to mobile wireless devices is described. When the mobile broadcast service center receives a request to deliver a broadcast video channel to a target mobile wireless device, it designates as target an intermediate node in the network that serves the target mobile wireless device. The mobile broadcast service center first determines if an existing channel bundle is routed to the target intermediate node. If this first determination is negative, the mobile broadcast service center routes a new channel bundle to the target intermediate node, including the requested broadcast video channel. If the first determination is positive, the mobile broadcast service center then determines if the requested broadcast video channel is in the existing channel bundle. If this second determination is negative, then it adds the requested broadcast video channel to the existing channel bundle.

主权项 1. A method, comprising: routing, by a network device comprising a processor, streamed content over a first routing path in a network to a first radio network controller for delivery to a first base station that delivers the streamed content to a first mobile communication device, wherein the streamed content is associated with a broadcast video channel; storing, by the network device, information indicating that the streamed content is being delivered to the first radio network controller via a support node positioned in the network between the first radio network controller and a source gateway router; receiving, by the network device, a request from a second radio network controller to deliver the streamed content to a second mobile communication device serviced by a second base station coupled to the second radio network controller; determining, by the network device, that the streamed content is being delivered to the first radio controller via the support node according to the information; adjusting, by the network device, the first routing path to generate a second routing path originating at the support node for routing the streamed content to the second radio network controller for delivery to the second mobile communication device via the second base station while continuing to route the streamed content to the first radio network controller via the support node, wherein the routing of the streamed content to the second radio network controller is performed without providing a notification to the source gateway router or to a mobile broadcast service center that initiated the broadcast video channel; receiving, by the network device from the source gateway router, the streamed content; and adjusting, by the network device, a group of channel bundles according to channel bundle changes initiated by a mobile broadcast service center to satisfy user content requests, wherein the information is added to a channel bundle.
