Abstract: A method for dynamically building and maintaining call priority information for use in emergency calls from a client device to an emergency call center is provided. The method provides a plurality of communication connections operable on at least one communication system, and each of the plurality of communication link comprises a plurality of metrics. The method further determines by the client device whether each of the plurality of communication connections is active, and evaluates each of the plurality of metrics for each of the active communication connections, and orders sequentially the plurality of active communication connections based on at least one of the plurality of evaluated metrics.

Abstract: An apparatus and method for rapidly providing activity on a vehicle network bus includes a node having a bus connection to the vehicle network bus. The node includes a Rapid Response Stack loaded with the predetermined message to respond to any network bus request before the application is up and running. A true stack is loaded with real messages from the application once it is booted up and running on the node, whereupon the application subsequently responds to network bus requests using the true stack instead of the Rapid Response Stack.
