Distributed trunking mechanism for VHF networking
First Claim
1. A method of ranking connection requests in a communication network that includes a plurality of nodes communicating over a radio channel, comprising the steps of:
- (a) providing a plurality of connection requests to one of the plurality of nodes, each request identifying a destination node to be connected to;
(b) assigning a set of parameters to each connection request wherein the set of parameters assigned to each connection request further comprises;
(i) a parameter identifying the urgency of the connection request;
(ii) a parameter identifying the loss priority of transmitting the connection request; and
,(iii) a parameter identifying the importance of the connection request relative to other connection requests;
(c) monitoring the age of each connection request;
(d) ranking the each one of the plurality of the connection requests based on the values of each assigned parameter and the age of the each one of the plurality of the connection requests; and
(e) transmitting the highest ranked connection request, wherein a lower priority connection request may be transmitted before a higher priority connection request if the transmission of the lower priority request does not violate the service deadline of the higher priority packet.

Abstract
A system and method for communicating between nodes in a communications network. The network includes nodes that broadcast and receive data packets over a radio channel. The system includes a distributed trunking method that distributes the communications between the nodes over multiple channels. Voice and other data may be broadcast over data channels, while information regarding the availability of the data channels is broadcast over a control channel. Access to the control channel is controlled using a protocol that may include carrier sense multiple access with collision avoidance (CSMA/CA), time division multiple access (TDMA) or a hybrid of CSMA/TDMA.
