Abstract

Abstract A method and apparatus for delivering media to a group of target communication devices provides for multicasting media to the group of target communication devices to save network resources. The disclosed embodiments provide for a significant reduction in network traffic and media processing time by transmitting media in multicast transport mode, where a single copy of the media destined for a group of target recipients is transmitted to a wireless infrastructure over the multicast path. The wireless infrastructure replicates and transmits one copy of the media to each of the target recipients that are assigned to dedicated channels, but multicasts one copy of the media to the target recipients that are assigned to a shared channel.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 152 words
A method for multicasting media to a group of target communication devices in a wireless communication network, the wireless communication network including a wireless infrastructure and a group call server (GCS), the method comprising: multicasting one copy of the media from the GCS to the wireless infrastructure for transmission to the group of target communication devices; transmitting one copy of the media from the wireless infrastructure to each of a first plurality of target communication devices within a first zone; multicasting one copy of the media from the wireless infrastructure to a second plurality of target communication devices within a second zone; replicating, by the wireless infrastructure, the media for transmission to said each of the first plurality of target communication devices; and wherein said transmitting to each of the first plurality of target communication devices includes transmitting one copy of the media on a forward dedicated channel of the wireless infrastructure.
Claim 2
Independent Claim 152 words
A method for multicasting media to a group of target communication devices in a wireless communication network, the wireless communication network including a wireless infrastructure and a group call server (GCS), the method comprising: multicasting one copy of the media from the GCS to the wireless infrastructure for transmission to the group of target communication devices; transmitting one copy of the media from the wireless infrastructure to each of a first plurality of target communication devices within a first zone; multicasting one copy of the media from the wireless infrastructure to a second plurality of target communication devices within a second zone; replicating, by the wireless infrastructure, the media for transmission to said each of the first plurality of target communication devices; and wherein said transmitting to each of the first plurality of target communication devices includes transmitting one copy of the media on a forward dedicated channel of the wireless infrastructure.
Claim 3
Dependent Claim 152 words
A computer-readable medium embodying a method for multicasting media to a group of target communication devices in a wireless communication network including a wireless infrastructure and a group call server (GCS), the method comprising: multicasting one copy of the media from the GCS to the wireless infrastructure for transmission to the group of target communication devices; transmitting one copy of the media from the wireless infrastructure to each of a first plurality of target communication devices within a first zone; multicasting one copy of the media from the wireless infrastructure to a second plurality of target communication devices within a second zone; replicating, by the wireless infrastructure, the media for transmission to said each of the first plurality of target communication devices; and wherein said transmitting to each of the first plurality of target communication devices includes transmitting one copy of the media on a forward dedicated channel of the wireless infrastructure.
Claim 4
Dependent Claim 152 words
A computer-readable medium embodying a method for multicasting media to a group of target communication devices in a wireless communication network including a wireless infrastructure and a group call server (GCS), the method comprising: multicasting one copy of the media from the GCS to the wireless infrastructure for transmission to the group of target communication devices; transmitting one copy of the media from the wireless infrastructure to each of a first plurality of target communication devices within a first zone; multicasting one copy of the media from the wireless infrastructure to a second plurality of target communication devices within a second zone; replicating, by the wireless infrastructure, the media for transmission to said each of the first plurality of target communication devices; and wherein said transmitting to each of the first plurality of target communication devices includes transmitting one copy of the media on a forward dedicated channel of the wireless infrastructure.
Claim 5
Independent Claim 155 words
An apparatus for multicasting media to a group of target communication devices in a wireless communication network including a wireless infrastructure and a group call server (GCS), comprising: means for multicasting one copy of the media from the GCS to the wireless infrastructure for transmission to the group of target communication devices; means for transmitting one copy of the media from the wireless infrastructure to each of a first plurality of target communication devices within a first zone; means for multicasting one copy of the media from the wireless infrastructure to a second plurality of target communication devices within a second zone; replicating, in the wireless infrastructure, the media for transmission to said each of the first plurality of target communication devices; wherein said means for transmitting to each of the first plurality of target communication devices includes means for transmitting one copy of the media on a forward dedicated channel of the wireless infrastructure.
Claim 6
Independent Claim 155 words
An apparatus for multicasting media to a group of target communication devices in a wireless communication network including a wireless infrastructure and a group call server (GCS), comprising: means for multicasting one copy of the media from the GCS to the wireless infrastructure for transmission to the group of target communication devices; means for transmitting one copy of the media from the wireless infrastructure to each of a first plurality of target communication devices within a first zone; means for multicasting one copy of the media from the wireless infrastructure to a second plurality of target communication devices within a second zone; replicating, in the wireless infrastructure, the media for transmission to said each of the first plurality of target communication devices; wherein said means for transmitting to each of the first plurality of target communication devices includes means for transmitting one copy of the media on a forward dedicated channel of the wireless infrastructure.
Claim 7
Independent Claim 161 words
