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 towards a first radio network controller for delivery to a first base station that delivers the streamed content to a first mobile communication device; detecting, by the network device, a request to deliver the streamed content to a second mobile communication device; adjusting, by the network device, the first routing path to generate a second routing path to a second radio network controller that delivers the streamed content to the second mobile communication device via a second base station while continuing to route the streamed content to the first radio network controller via a support node, wherein the second routing path includes the support node, wherein routing of the streamed content to the second radio network controller is performed without providing a routing adjustment notification to equipment of a gateway node or to a mobile broadcast service center that is associated with streaming of the streamed content; and receiving, by the network device from the equipment of the gateway node, the streamed content, wherein routing information is generated that indicates that the streamed content is being delivered to the first radio network controller via the support node positioned in a network between the first radio network controller and the equipment of the gateway node.
