Location specific event broadcasting
First Claim
1. A system for broadcasting events to fine-grained locations in a network, the system comprising:
- a broadcast location manager installed on a server, the broadcast location manager comprising;
a policy manager configured to define a physical location in a network to which events are broadcast, wherein the physical location is smaller than an area served by the network, the policy manager being further configured to define a fine-grained location within the physical location, wherein an event is to be distributed to client devices within the fine-grained location,a topology manager configured to generate a client topology table which includes a mapping of location tags to physical locations in the network, wherein each physical location is identified by a network address,an intake manager configured to provide an event to be distributed to the fine-grained location with a location tag, anda broadcast manager configured to broadcast events to the physical location; and
a client location filter installed on a client device and coupled to the broadcast location manager by a broadcast distribution network, the client location filter comprising;
a client topology table manager comprising the client topology table, andan event filter configured to determine whether the client device is located in the fine-grained location based on the location tag and the client topology table,wherein the event is forwarded to the corresponding application in the client device when the client device is located in the fine-grained area of the network.

Abstract
Applications in a broadcast environment distribute events in real-time to a large number of receivers within specified geographic locations while efficiently sharing bandwidth resources with other applications using the same broadcast network. Applications need not be aware of the other applications sharing the resources, nor of the methods, protocols, and other mechanisms used to actually broadcast the data over the broadcast medium. Server-side applications that serve data, send notifications, or distribute events to specific locations within the network use a broadcast location manager. Client applications that receive such data, notifications, or events use a client location filter to obtain events that are relevant based on the location of the device. The broadcast location manager and client location filter work together to reliably and efficiently transmit data, notifications, and events to specific locations over the broadcast network for all applications involved.
