Abstract

A method and system for peer to peer wide area network communication is provided. A peer in the network receives one or more media and one or more associated control signaling from any one of a plurality of Logical Media/Control Channels, wherein each Logical Media/Control Channel is associated with a Transport Resource on a base station; formats the media into a Formatted Media Packet; formats the control signaling into an Internet Peer to Peer Control Signaling; concatenates the Formatted Media with the Internet-Peer to Peer Control Signaling to form a Concatenated Packet comprising an Internet-Peer to Peer Control Signaling and a Media Packet; duplicates the Concatenated Packet, thereby forming a duplicated Concatenated Packet comprising at least one of a unicast packet and a multicast packet; and transmits the duplicated Concatenated Packets via the wide area network.

Claims

1. A method of operation of a peer within a distributed peer to peer wide area network, the wide area network comprising a plurality of network locations, each network location consisting of at least one peer and at least one base station, the method comprising:

receiving one or more media and one or more associated control signaling from any one of a plurality of Logical Media/Control Channels, wherein each Logical Media/Control Channel is associated with a Transport Resource on a base station;

formatting the media into a Formatted Media Packet;

formatting the control signaling into an Internet Peer to Peer Control Signaling;

concatenating the Formatted Media with the Internet-Peer to Peer Control Signaling to form a Concatenated Packet comprising an Internet-Peer to Peer Control Signaling and a Media Packet;

packet duplicating the Concatenated Packet, thereby forming a duplicated Concatenated Packet comprising at least one of a unicast packet and a multicast packet; and

transmitting the duplicated Concatenated Packets to at least one other Peer via the wide area network.

2. The method of claim 1, wherein the transmitting step comprises:

transmitting at least one of the duplicated Concatenated Packets through a Socket, wherein the Socket interfaces to the wide area network, and further wherein the socket comprises an Internet Protocol Address and a Port Number of at least one destination Peer and the Internet Protocol Address and Port Number of the source Peer wherein the socket is dedicated to communication with at least one of the Peers on the wide area network.

3. The method of claim 1, further comprising:

generating a Hash over the Concatenated Packet prior to the packet duplicating step.

4. The method of claim 3 further comprising prior to the generating the Hash step:

encrypting the Concatenated Packet; and

generating a Sequence Number of the Concatenated Packet.

5. The method of claim 1, wherein the wide area network comprises at least the Public Internet.

6. The method of claim 1, wherein the media comprises audio media, and wherein the step of formatting the media into a Formatted Media Packet comprises:

formatting the audio media within a Real-time Transport Protocol.

7. The method of claim 1, wherein the media comprises data, and wherein the step of formatting the media into a Formatted Media Packet comprises:

formatting the data within Peer to Peer Data Packets.

8. The method of claim 1, wherein the received control signaling associated with the media includes at least one of a Priority, a Destination Talkgroup, a Source Mobile Radio Identification, a Call Type, and a Transport Resource Number.

9. The method of claim 1, wherein the Internet Peer to Peer Control Signaling includes a Random Number.

10-26. -26. (canceled)

27. A method of operation of a Peer within a distributed peer to peer wide area network, the method comprising:

within an Internet Jitter Buffer Length Optimizer of the Peer;

evaluating a (99+x)% worst jitter between the Peer and all other Peers; and

setting all Internet Jitter Buffer lengths to the next highest multiple of at least the sum of the worst case serialization delay plus the (99+x)% worst jitter between itself and all other Peers where 0<

=x<
