A method for reducing call dropping rates in a multi-beam communication system. The multi-beam communication system includes a user terminal, a gateway, and a plurality of beam sources, where each beam source projects a plurality of beams, and where a communication link between the user terminal and the gateway is established on one or more beams. The method according to the present invention relies on a messaging protocol between the gateway and the user terminal. Based on messages sent from the user terminal to the gateway, preferably on a preselected periodic basis, the gateway can determine the more desirable beam(s) for transmitting data or information to the user terminal. The messages sent from the user terminal to the gateway contain values representing beam strengths as measured at the user terminal. The gateway uses the user terminal measured beam strengths to select the beams that should be used for transmitting data or information to the user terminal. The beams that should be used are the beams that if used will decrease the call dropping rates and provide a desired level of beam source diversity.

System and method for reducing call dropping rates in a multi-beam communication system

A system for communication between a fleet of vehicles and a central base station, where each of the vehicles includes one or more vehicle subsystems connected to a vehicle data link, is disclosed herein. Within each vehicle, message packets generated by vehicle subsystems are placed upon the vehicle data link. Each message packet includes header information identifying a given vehicle and subsystem thereof. The message packets are transmitted from the fleet of vehicles to the central base station, and routed within the central base station based on the header information. Control information and the like may also be transmitted by the central base station for receipt by various vehicle subsystems within selected ones of the fleet vehicles. Each message packet generated by the central base station includes header information identifying at least a particular fleet vehicle and vehicle subsystem. This allows each message packet to be retrieved by the specified vehicle subsystem by way of the vehicle data link.
