Territory mapping for efficient content distribution in wireless networks using broadcast/multicast
First Claim
1. A method for providing a content delivery service to subscribers in a wireless network comprising the steps of:
- receiving a description of a desired broadcast/multicast (BCMC) territory in terms of an extent of a physical area;
receiving a content indicator associated with the BCMC territory, such content indicator to be supplied to subscribers located in the BCMC territory;
estimating cell sector coverage areas for one or more cell sectors;
identifying a set of targeted cell sectors, by using the BCMC territory description and the estimated cell sector coverage areas to identify the set of targeted cell sectors as those sectors that relate to the BCMC territory; and
sending the content indicator to the set of targeted cell sectors using a BCMC protocol.

Abstract
A technique for content delivery in wireless networks which associates a desired broadcast/multicast (BCMC) territory with the content, estimates cell sector coverage area from a subscriber location data set, and then identifies a set of cell sectors to be sent the content using a BCMC protocol. The method involves first receiving a description of a designated broadcast/multicast (BCMC) territory in terms of a physical area. Next, a content indicator associated with the BCMC territory is identified. The content indicator identifies content, such as text or image data, that is to be supplied to subscribers located in the territory. A cell sector coverage area is then estimated from a subscriber location data set wherein the data set includes at least a geographic location and a cell sector identifier for multiple subscribers. The BCMC territory description and the estimated cell sector coverage areas are then compared against the subscriber location data set to identify a set of targeted cell sectors. Finally, the content indicator is then sent to the set of targeted cell sectors using a BCMC protocol.
