METHOD FOR DISTRIBUTING MEDIA IN AN INFRASTRUCTURE BASED COMMUNICATION SYSTEM
First Claim
1. A method for media distribution in an infrastructure-based communication system, the method comprising:
- acquiring membership in a first predefined group comprising a plurality of wireless communication devices where distribution of media within the first predefined group is managed by a first infrastructure device;
joining a first ad hoc network associated with the first predefined group and comprising as nodes a subset of the plurality of wireless communication devices, wherein one of the nodes of the first ad hoc network is selected as a duplicator node for the first ad hoc network;
participating in a session for distributing media to the first predefined group; and
if serving as the duplicator node, then receiving the media from the first infrastructure device and distributing the media to the other nodes of the first ad hoc network, otherwise receiving the media from the duplicator node.

Abstract
A wireless communication device acquires membership in a predefined group, joins an ad hoc network associated with the predefined group, and joins and participates in a first session established through an infrastructure device for distributing media to the predefined group. If the wireless communication device is a duplicator node for the ad hoc network, then it receives the media from the infrastructure device and distributes the media other nodes of the ad hoc network, otherwise it receives the media from the duplicator node. The infrastructure device identifies the duplicator node for each ad hoc network associated with the predefined group and each member of the predefined group that is not a node of any of the ad hoc networks and distributes the media only to these members of the predefined group.

12. A method for media distribution in an infrastructure-based communication system, the method comprising:
-
establishing a session for a predefined group having as members a plurality of wireless communication devices where distribution of media within the predefined group is managed by a first infrastructure device, wherein the first predefined group has associated therewith at least one ad hoc network, with each ad hoc network being formed by and between a different subset of the members of the predefined group, with one wireless communication device of each subset being selected as a duplicator node for the corresponding ad hoc network; identifying the duplicator node for each ad hoc network and each member of the predefined group that is not a member of any of the ad hoc networks; and distributing media for the session to only the members of the predefined group that are not a node of any of the ad hoc networks and to the duplicator nodes for distributing to the remaining members of the predefined group that have joined the session. - View Dependent Claims (13, 14, 15, 16)
