Such estimates can be used to target specific network features that limit network performance. | 12-17-2015 |
20160119686 | ON DEMAND MOBILE WIRELESS BROADCAST VIDEO DELIVERY MECHANISM - 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. | 04-28-2016 |
