Abstract: Method for reducing call dropping rates in a multi-beam communication system that includes a user terminal, a gateway, and a plurality of beam sources projecting a plurality of beams, and where a link between the user terminal and the gateway is established on one or more beams. The method relies on a messaging protocol between the gateway and the user. Based on messages sent from the user to the gateway, preferably on a preselected periodic basis, th e gateway determines the more desirable beam(s) for transmitting to the user. The messages sent from the user to the gateway contain values representing beam strengths as measured at the user. The gateway uses the user measured beam strengths to select the beams that should be used for the user. The bea ms to be used are the beams that will decrease the call dropping rates and provide a desired level of beam source diversity.

Abstract: 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.
