Abstract

A method for subscriber registration and affiliation in a peer to peer wide area network is provided. The peer to peer wide area network includes at least one Subscriber and a plurality of Peers. The method includes: communicating a registration and affiliation message including a Subscriber Registration Affiliation Index from a Subscriber to a Peer of the plurality of Peers; routing a registration and affiliation update message including a Peer Registration Affiliation Index equal to the received Subscriber Registration Affiliation Index from the Peer to other Peers of the plurality of Peers; comparing the received Peer Registration Affiliation Index with one or more other received Peer Registration Affiliation Indexes by each of the plurality of Peers; and selecting by each of the plurality of Peers a Peer Registration Affiliation for the Subscriber corresponding to a highest value Peer Registration Affiliation Index.

Claims

1. A method for subscriber registration and affiliation in a peer to peer wide area network, the peer to peer wide area network comprising at least one Subscriber and a plurality of Peers, the method comprising:

communicating a registration and affiliation message including a Subscriber Registration Affiliation Index from a Subscriber to a Peer of the plurality of Peers;

routing a registration and affiliation update message including a Peer Registration Affiliation Index equal to the received Subscriber Registration Affiliation Index from the Peer to other Peers of the plurality of Peers;

comparing the received Peer Registration Affiliation Index with one or more other received Peer Registration Affiliation Indexes by each of the plurality of Peers; and

selecting by each of the plurality of Peers a Peer Registration Affiliation for the Subscriber corresponding to a highest value Peer Registration Affiliation Index.

2. A method as claimed in claim 1, wherein the registration and affiliation message further includes a Subscriber identification and a talkgroup affiliation.

3. A method as claimed in claim 1, further comprising:

communicating an acknowledgement message from the Peer to the Subscriber including the Peer Registration Affiliation Index;

comparing the Peer Registration Affiliation Index received with a current Subscriber Registration Affiliation Index of the Subscriber; and

when the Peer Registration Affiliation Index does not match the Subscriber Registration Affiliation Index, sending the current registration and affiliation index from the Subscriber to the Peer.

4. A method as claimed in claim 3, wherein the acknowledgement message further includes a Peer identification and a Subscriber identification.

5. A method as claimed in claim 1, further comprising:

detecting a personality change at the Subscriber, wherein the personality change comprises one or more of a talkgroup affiliation, a frequency of operation, and an affiliation with an identified Peer;

incrementing the Subscriber Registration Affiliation Index of the Subscriber; and

sending a registration and affiliation message including the incremented Subscriber Registration Affiliation Index to the identified Peer.

6. A method as claimed in claim 1, further comprising:

detecting an expiration of a timer requiring a renewal of a personality state of the Subscriber within the peer to peer wide area network;

incrementing the Subscriber Registration Affiliation Index of the Subscriber; and

sending a registration and affiliation message including the incremented Subscriber Registration Affiliation Index to the identified Peer.

7. A method as claimed in claim 1, further comprising:

detecting an expiration of an acknowledgement timer by the Subscriber without receipt of an acknowledgement message from the Peer; and

retransmitting the registration and affiliation message to the Peer.

8. A method for subscriber registration and affiliation in a peer to peer wide area network, the peer to peer wide area network comprising at least one Subscriber and a plurality of Peers, the method comprising:

affiliating a Subscriber with a first Peer on a first frequency and within a first talkgroup by communicating a registration and affiliation message including a registration and affiliation index from the Subscriber to the first Peer;

selecting a second Peer on a second frequency and within a second talkgroup by the Subscriber for communication;

incrementing the registration and affiliation index at the Subscriber;

affiliating the Subscriber to the second Peer on the second frequency and within the second talkgroup by communicating a second registration and affiliation message including the incremented registration and affiliation index from the Subscriber to the second Peer;

updating the plurality of Peers of the registration and affiliation of the Subscriber by the first Peer transmitting the registration and affiliation index;

updating the one or more other Peers of the registration and affiliation of the Subscriber by the second Peer transmitting the incremented registration and affiliation index; and

identifying the Subscriber as registered and affiliated with the second Peer by the plurality of Peers based on the higher value of the incremented registration and affiliation index.
